What You Need

• A Windows PC (Linux dudes, you already know how to do this, right?)
• A Mac
• A router to connect them

Before we get into sharing between computers directly, are you sure you don't just want a NAS?

Talk to Me, Girl

So, assuming that your PC and Mac are both sitting comfortably on your network, wirelessly or otherwise (if you haven't gotten that far, you need more help than I'll be providing right here), there are a couple of different ways for the various machines on your network to talk to each other and share files. Think of 'em sorta like languages.

• SMB (Server Message Block) aka CIFS (Common Internet File System) is Windows' preferred network file sharing protocol, and luckily, Macs speak it, so this how your computers will most likely be talking and sharing stuff. Vista and Windows 7 use SMB 2.0, which is mo' faster for file transfers.

• FTP (File Transfer Protocol) is one you know and love, if you've ever spent any time on the internet. It's one option for sharing stuff between your Mac and PC.

• NFS (Network File System) is the protocol Unix-based systems like to use for sharing files, which both Windows and Macs can understand. A lot of NASes use it.

• AFP (Apple Filing Protocol) is like a secret language for Macs, 'cause Windows sure as crap don't speak it. But from Mac-to-Mac, it's what makes sharing just work (when it does).

Things That Will Help

My goal here is to show you how to share files between your PC and Mac easily, and for the most part, without worrying about things like IP addresses or diddling with your router's settings. But! If you want to make troubleshooting easier—this kind of networking is more voodoo than science—there are a few things you could stand to know and do beforehand.

1. Know your router. Or really, know how to get into it. For most routers, punching the number soup 192.168.1.1 (Linksys, for instance) or 192.168.0.1 (D-Link, for example) into your web browser will take you to the router's settings, where you can fiddle with things (which you hopefully already did to protect your network).

2. Make everything static. If you take your computer on and off the network a lot, odds are, your router isn't going give it the same IP address every the computer jumps back on, because it hands those addresses out dynamically (you might recognize this as DHCP in action, if you're wondering what that acronym refers to). For consistency's sake, it's not a bad idea to assign your computers static IP addresses on the network, so they'll always have the same address—I at least give my desktop PC and Xbox static IP addresses—just in case something else is broken.

Look in the router settings for a reference to DHCP reservations or static DHCP, which is most likely under the general settings tab. Hit that up, like so, and you should see a list of computers on your network, along with their MAC addresses (an ID tied to the actual networking card in your computer) and currently assigned IP address (something like 192.168.1.102). If your computer's already connected to the network and listed here, it's real easy to give it an unwavering address on your network, a matter of a couple checkboxes.

If, for some reason, your computer's not on the network and you wanna give it a static address, like 192.168.0.104, you're gonna need to know its MAC address. On a Mac, just open the Network Utility app and select AirPort—it's the "hardware address." In Windows Vista and 7, go to Network & Sharing Center, and tap view status link next to your connection. Hit "details" in the pop up box and note the "physical address." On XP, bring your network connections, double click the one you want, flip to the "support" tab, and hit details. It's the physical address. Now that you have the MAC address for your computers, you can assign a set IP address to each one, that it'll have every single time it's on the network, which is a handy list to have.

Getting Ready

Okay, let's get our machines ready. We'll start with the Mac, 'cause it's a little easier.

Mac
1. Setup a user account for sharing, either under Accounts or Sharing -> File Sharing in System Preferences. (Unless you just wanna log in from Windows using your regular Mac login, then you can skip creating a sharing account.) Click the little plus sign under users, and then you pull can a name out of your address book to use for the account, or setup a whole new one.

2. Open system preferences, go to sharing if you haven't already, and check the box for file sharing. Click options, and enable AFP (if you've got other Macs you wanna share with) and SMB. Crucially, make sure the account you're gonna be logging in from Windows with has SMB enabled.

3. To pick the folders you wanna share with other users, click the little plus sign and browse to the folder you wanna give access to. Maybe it's your pictures, maybe it's your whole Home folder. You'll need to add each folder individually, especially if you wanna give different people access to different folders. (If you're logging in from Windows with your standard Mac account, you'll have access to your whole hard drive anyway.)

After you've picked the folder you wanna share, then you just pick the user you want to share with, and how much access you want them to have. Read-only, write-only or read and write.

4. Note your computer's name on the local network. It's sitting on top of the main file sharing setting page. And, if you've got AFP turned off, you'll get this dialog, noting the IP address Windows users can access your stuff.

5. Go back to the main system preferences page, then click on Network. Go to the main connection you'll be using, like AirPort, and click advanced. Go to WINS, and set your Workgroup to the same one as your Windows PCs (probably either WORKGROUP, on newer Windows machines or MSHOME on XP).

Windows 7 and Windows Vista
In Windows 7 and Vista, the Network and Sharing Center is where we'll be spending our time. (Here's Microsoft's own guide, if you wanna check it out.)

1. First, make sure in your little path to the internet up top, you've got a picture of a house sitting between your computer the internet globe at the top. That means you've got it set to private network, so stuff's a little more exposed to other computers on the network. If not, click customize to the right of the network name, and set it to private network.

2. In Vista, you'll notice the big ol' Sharing and Discovery section up front and center. In Windows 7, it's under advanced sharing settings. Go in there, and you'll want to enable network discovery, and make note of your Workgroup (so you can make sure your Mac is on the same one) which is listed here. Also, you have the option to turn off password-protected sharing, so that you don't need an account on the machine set up for sharing. Obviously, it's less secure, but if you prefer convenience, that's up to you.

3. Now for some voodoo that's not required, but it'll make life easier and might be something you need to come back to if stuff isn't working, because OS X and Windows shake hands like goons (really it's about tweaking the LAN Manager Authentication Level, so OS X has an easier time connecting to Windows). If you have Windows 7 or Vista Ultimate, go to the Control Panel, then Administration Tools, then local security policy. Hit local policies, then security options, and look for Network Security LAN Manager Authentication Level. There, you want to switch it to "send LM & NTLM, use NTLMv2 session if negotiated."

If you're in Windows 7 or Vista Home Premium, you don't have access to that, so you'll need to registry hack it up. Open up regedit, and look for this:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\LSA\

Double click on LmCompatibilityLevel, and set the value to 1.

For more on this, just Google "vista mac NTVLM2." (Sans period.)

4. Now, we'll need to set up an account to share with. (Again, you can skip this if you're just going to use your regular Windows login from your Mac, though you'll need to have a password on the account for it to work best in Vista.) Go to User Accounts in Control Panel, then to Manage Accounts. Create a new account.

5. If you're going to be logging in with your main administrator account, you can skip this step, since you'll have access to everything anyway. For all other accounts, go to the folder you want to share, right-click on it and hit properties. Click the sharing tab, hit "share," and then you can add users to the share list, along with their permissions. Windows will share it, and give you the network path where you can access it. Alternatively, go to Computer, right-click, and check out the system properties and note your computer's name on the network and its Workgroup (make sure the Workgroup is the same as your other computers, it makes life easier).

Windows XP
XP's interface feels pretty damn ancient when it comes to Networking. Anyways, it's mostly the same stuff, just with a slightly uglier interface. I found this guide helpful when I was trying to remember where everything was.

1. Like before, you'll need a user account and password setup. Go to control panel, user accounts and create a new one, if you need to.

2. Make sure you're on the same workgroup as everything else—XP Home defaults to MSHOME, so if you need to change it, right-click on My Computer, hit properties, then go to Computer Name, and go to "Change" if you need to switch up the Workgroup.

3. Go to the folder you wanna share, right-click, hit properties, and switch over to sharing. Allow it to be shared over the network, and allow users to change files.

Sharing Stuff

Okay, if you've done everything correctly, and the gods are pleased, what you should see on your Mac in your Finder Sidebar under the Shared tab is your Windows computer. (Make sure Shared is enabled in your Finder sidebar preferences, or you won't see it.) Then, you should be able to just click on it, enter your user account and password, and voila, you can get right at everything just like you hoped.

On your Windows 7 or Vista machine, you should be able to click Network, and see all of your connected computers, including your Macs. To login, as Ross McKillop points out, your username is the name of the Mac followed by the OS X username, like this, minus the quotes and period: "MATTBOOK-PRO/matt." In XP, you'll go to My Network Places or Workgroup, and it should be the same deal, though you can just stick to the actual Mac username and password. Life's good.

Update: BTW, if you have Apple's Bonjour—Apple's zero configuration networking dealio, which powers music sharing in iTunes—installed on your Windows machines (it comes with iTunes), the discovery part of the guide above—the parts pertaining to locating the other machines on your network, should just work. That is, your Windows machines should just show up in your Finder sidebar and your Mac in your PC's Networking page, though you still need the accounts setup properly to actually share stuff.

Sometimes, things don't work like that. PCs don't show up in the Finder automagically, you can't login easily from your PC. Network discovery just isn't always that reliable. In that case we go all manual mode. Remember earlier, when I had you note your computer's name on the network and setup a static IP? That's where this comes in handy. So, know either your computers names, or their IP addresses on your network.

On a Mac, it's pretty simple. Go to Finder, tap command+k and punch in:

smb://computername or smb://192.168.X.XXX

The latter is the PC's IP address, which should be something like 192.168.0.105—unless you have a weird setup—though the last two numbers of it will obviously vary. The computer name is easier and usually better, especially if you don't have a static IP address set up.

It'll ask you what volume to mount (what folder you want stuck on your Finder Sidebar under shared, essentially), and a login, and then you're good to go. If prefer the cmd+k approach, you can add computers you tap a lot as a favorite, so you don't have to type it in every time.

It's pretty simple in Windows too, actually. Either in the Windows Explorer address bar, or the Run command type:

\\MACNAME\Folder or \\192.168.X.XXX\Folder

And it should give you the option to login there, giving you access to all of your stuff. Using the full address of the folder you're trying to get to will help with making sure the authentication pop-up appears—otherwise you might just see automatically what's publicly shared and not the stuff you're trying to log into.

Shortcuts

Logging in every single time would be a pain in the dick, but luckily you can make shortcuts to this stuff. On a Mac, as Gina points out here, under Accounts, you can add a network share to login items, so it'll connect every time you start up your computer. In Windows, you can either create a shortcut by right-clicking on the share, or you can add your Mac's shared folder as a mapped network drive, so it'll connect to the folder every time you fire up your computer.

Apparently Psystar has until the final second of this year, midnight on December 31, to cease all of these activities:

• Copying, selling, offering to sell, distributing or creating derivative works of Mac OS X without authorization from Apple.
• Intentionally inducing, aiding, assisting, abetting or encouraging any other person or entity to infringe Apple's copyrighted Mac OS X software.
• Circumventing any technological measure that effectively controls access Mac OS X, including, but not limited to, the technological measure used by Apple to prevent unauthorized copying of Mac OS X on non-Apple computers.
• Playing any part in a product intended to circumvent Apple's methods for controlling Mac OS X, such as the methods used to prevent unauthorized copying of Mac OS X on non-Apple computers.
• Doing anything to circumvent the rights held by Apple under the Copyright Act with respect to Mac OS X.

It's noted that those rules laid down by judge William Alsup may not apply to "Psystar's Rebel EFI software, a $50 application that allows certain Intel-powered PCs to run Mac OS X 10.6 Snow Leopard," so this may not be the last we hear of the company. For now though, we can enjoy a few moments of quiet after this legal knockout. [Apple Insider]

Pastebot's core functionality is to act as a basic clipboard, collecting your various copied snippets and photos into a browsable archive. It can handle anything that the iPhone can natively, meaning text, photos and HTML content copy fine, while videos, audio, or browser plugin content don't. Once the data is collected, Pastebot can process it—photos can be run through filters, HTML can be parsed, text can be converted to uppercase or lowercase, etc. To put a clipping back onto the iPhone's main clipboard, you just select the item, and it's ready for pasting.

Pastebot's real victory is its free sync app, available for Mac. When this is running on a computer in the same wireless network as the iPhone, which is also running Pastebot, anything copied on the computer is immediately synced to the iPhone, and anything copied on the iPhone can be synced to the desktop, where it replaces whatever is currently in the OS X clipboard. Watching whatever you copy pour onto your iPhone is a joy, not least because the interface on this thing is beautiful.

My one gripe: Since apps can't run in the background, in order for Pastebot to collect what you've copy, it needs to be started. That's each time you copy something—if you couple more than one thing in a row and then open Pastebot, only the latest will show up. Still though, this is some tremendous utility for $2. [Pastebot]

Apple's decision to buy the ousted Jobs' NeXT Software was a last minute one. They were in fact looking to buy BeOS (now defunct), but the asking price was too high, and they went with NeXT for $400 million. Apple needed to buy the foundation for a new operating system, as their own OS development efforts at the time were, in a word, screwed. NeXTSTEP became the basis for OS X.

I say almost, because there was still some noticeable frame dropping. But still, I could actually watch HD flash video (windowed and full-screen) without it stuttering like a slideshow. One issue with YouTube: the CPU pretty much went into overload once the video was playing, and on the third viewing I had to Force Quit Firefox to wrestle back control.

But this is good news for hackintoshes, and netbooks in general. This is not hardware GPU acceleration (limited to Windows right now), it just seems to be better CPU usage. Earlier today I also posted about AnandTech's Flash 10.1 CPU-utilization tests: they still noticed improvements under OS X, too. If you've given Flash 10.1 a try, post a comment here so other readers can see what sort of netbook you have, and if it's worth trying.

For the record, my MSI Wind U100 has 2GB of memory, a 1.6GHz Atom N270 processor, and integrated Intel 945 graphics. (Pic above is of the Dell Mini 9).

All of Psystar's motions for summary judgment were denied, while all of Apple's were granted. That means that Apple got exactly what they wanted, while Psystar got exactly what they didn't want.

Don't worry, there will be a trial. According to Groklaw, the court still needs to determine (*deep breath*):

Apple's allegations of breach of contract; induced breach of contract, trademark infringement; trademark dilution; trade dress infringement; and state unfair competition under California Business and Professions Code § 17200; and common law unfair competition.

Phew! So yeah, at this point it's looking less like a trial to determine Psystar's legitimacy, more like a trial to decide how much they owe Apple.

Now, I'm no lawyer, but from where I'm standing this case is looking pretty grim for Psystar. I'll leave it to you legal eagles to explain exactly what all this means in the comments, because all I know is that it can't be good. [Groklaw via 9 to 5 Mac, image via walknboston]

A post on the Windows Blog entitled " How we really designed the look and feel of Windows 7" renounces Simon's quotes with a curt, yet harsh line:

Update: There appears to be some confusion regarding which sort of Hackintosh set up is affected by 10.6.2. If you are running something other than an Intel Atom-based netbook, you should be just fine, it's those relying on Atom-support who are in trouble with this one. [OS X Daily]

The video above shows what happens if you try to boot the latest 10.6.2 developer build on a Hackintosh. As you can see, not much. So if you're running OS X on Atom hardware, hold off on any updates until this whole mess gets sorted out. [OS X Daily]

The hidden tweaks are a mix of features that didn't quite make the final cut or were deemed too slight to deserve their own tick-box, and deep system changes that normally call for terrifying terminal commands. And they don't stop at Snow Leopard: Secrets, which has been around in one form or another for a while now, has collected a huge library of "gray" settings for other apps too, from Apple's various software suites to civilian apps like Skype and NetNewsWire. The app is free, and installs as a PrefPane. [Secrets via TUAW]

While CrunchGear was able to get Rebel EFI working, it is important to point out that we tried several times get the software up and running with no success on the same exact computer. Then we got this email from a frustrated reader:

2 weeks ago, I purchased Psystar's RebelEFI software. While I own several Macs, I also have a fairly new PC with a Core 2 Duo and Intel motherboard that I thought would be a perfect specimen.

Before I purchased the software, I downloaded the trial version of RebelEFI. Sure enough, I was able to boot and install OS X 10.6. I installed the RebelEFI utility in OS X and because it was a trial, the hardware compatibility feature was disabled. (Why this feature would be disabled in a trial version?) I called Psystar with several questions and asked what would happen if some of my hardware was not compatible? The sales person told me that they would be able to access the software's hardware compatibility list and be able to supply me with drivers for the incompatible hardware.

I purchased the software and ran the hardware compatibility test. It showed me lack of compatibility for my video, audio and USB 2.0, however there was no way to send them the results of this test. When I questioned this, I sent Psystar a tech support ticket through the software's Customer Support feature. I was told in a reply that I would have to fill out a DCR form. I asked what a DCR form is and where I could find it. (They assumed I would automatically know this information).

After not hearing anything for a week, I tried calling Customer Support and was greeted with a message that support is only handled via email. I again asked the same question via email and 3 days later I received a PDF file in response. It basically says I have to send Psystar my computer for them to make it completely compatible. WHAT???? At no point during the purchase was I told I may have to send them my computer. I am now in the process of trying to get my money back.

Mac OS X on any computer? FAIL

Send your computer to a shady hackintosh company that refuses to accept any responsibility for devices shipped to their lab? Yeah...I don't think so. But here's the proof (click and select "Full Size" to enlarge):

As the days have worn on, Psystar's response to this customer's issue has deteriorated to the point that they are no longer responding to his attempts to email for a refund. In fact, they stopped taking customer-support calls entirely, and have switched to a far less personal (and helpful) email-based help program.

In other words, a $50 solution to run OS X on a PC sounded too good to be true, and it looks like it is. So, I'm inclined to go with a flat out DO NOT BUY on this one. However, let me put the question to you—have you purchased this software? Did you experience a similar problem? [Thanks Brian!]

Like Fusion, Parallels supports OpenGL 2.1 and DirectX 9 Shader Model 3.0 for the full Aero 3D interface and 7x better graphics performance than before. It also has a migration tool to move a PC's info to your virtual machine. Overall performance-wise, it's three times faster than before, supports 8 virtual CPUs and automatically pauses the virtual machine whenever no Windows apps are running. Update: The Parallels guys point out that Fusion supports OpenGL 2.1 just in XP, but only 1.4 in Vista and Windows 7, while Parallels supports 2.1 in every version, which they say means games will run better in Parallels. We'll definitely be checking that out.

The new Crystal mode promises to make "Windows completely disappear" so apps run feel completely native, with full support for multitouch trackpad gestures and the Apple Remote, with a persistent Windows apps folder in the Dock. Parallels 5 is out today for $80 for the full version or $50 for the upgrade, though we don't blame you if you can't tell it apart from Fusion 3, so we'll be checking them out head to head soon. [Parallels]

The current recommendation is to stick with 10.6.1 if you're running Snow Leopard, or 10.5.8 if your Hackintosh has Leopard. You could also try upgrading to 10.6.2 using an older or modified kernel.

If this is a conscious strike by Apple, it's likely the Hackintosh community will find a work around, but it's definitely something to watch before your next update. [OS X Daily]

Before you answer the poll, keep this in mind: work machines don't count. Presumably, you made a personal choice between a Mac or a PC for your private computer—and that is the one we want to know about.

It now supports OpenGL 2.1 and DirectX 9 Shader Model 3.0, giving you some more graphics powah in Windows, so you can run Windows' Aero interface with Flip3D (and play games, if you're daring). The more integrated Windows apps respond to commands like cmd+q and yes, work with Dock Expose. It's $80 for a fresh copy or $40 for an upgrade. [VMWare via AppleInsider]
