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]

Like last year's most popular Mac downloads, this list is based on the popularity of apps we've covered in 2009, regardless of the original release date of the app. Many were brand new this year, while others were solid updates to popular software. If you took a look at yesterday's Most Popular Free Windows Downloads of 2009, a few of the cross-platform favorites may look familiar. (I've rounded up the most popular cross-platform downloads at the bottom of the post.)

Snow Leopard: The Feisty Kitty That Could (and No, It's Not Quite Free, Either)

The release of Snow Leopard was nearly as big a deal for Mac users this year as Windows 7 for Windows folks, and while it was never strictly a download (unless you grabbed it from less reputable means), it's worth highlighting. Over the course of the year, we helped out by prepping your Mac for Snow Leopard, highlighted its biggest improvements, and held your hand while upgrading. If you didn't want to pony up for Apple hardware, we even showed you how to install Snow Leopard on your Hackintosh PC, no hacking required—and luckily for the frugal among us (no, this one's not free, but it was a big deal in the OS X world so we figured we'd include it), the $29 upgrade disc worked whether or not you were upgrading from Leopard.

2009 Was Still a Year of the Jailbreak

The iPhone hardware may be getting better and better, but Apple still hasn't gotten any better at opening up the app store to, oh, competition. As long as that's the case, jailbreaking apps like PwnageTool and QuickPwn will still be extremely popular. Read more >>

Magnifique Customizes Your OS X Theme

The release of Snow Leopard didn't do all that much to change Leopard's spots, but Magnifique certainly does. This free skinning app is full of user-generated Leopard-customizing goodies. Note: Magnifique does not support Snow Leopard, so you'll want to steer clear of it if you've upgraded. Unfortunately the Magnifique development seems to be at a standstill at the moment.

DoubleTwist May Be the Coolest Universal Media Manager Ever

People fed up with iTunes' restrictive stance on non-Apple devices (see Apple and Palms' dance, for example) were very interested in doubleTwist, a universal media manager that automatically converts files to the appropriate formats and seamlessly syncs them to your PSP, Android device, BlackBerry, and more.

Google Quick Search Like Quicksilver from Google

A lot of people were disappointed to learn about Quicksilver's grim future a while back, but many of you were heartened to learn that Quicksilver's creator had released a similar tool working with Google called Quick Search Box. Then again, it appears Quicksilver's not entirely dead just yet (see below).

Pollux Automatically Cleans and Tags Your iTunes Library

For all the access to track metadata contained in the iTunes store, iTunes is a slouch at cleaning and tagging mislabeled or poorly labeled tunes. Pollux was an absolutely killer iTunes supplement that grabbed song, artist, album, and other metadata names, along with lyrics and album art, quickly and accurately. The problem? Shortly after we highlighted it, Pollux was shut down because the APIs it accessed stopped letting it access them for free. We liked Pollux better, but if you're looking for something similar, check out TuneUp (free and pay versions available).

Picasa for Mac Beta Released, First Look

After years of Windows-only support, Google released the first Mac version of Picasa at the beginning of the year, and it didn't take long before the majority of our Mac readers preferred it to iPhoto. You go, Google.

Quicksilver Releases Update, Improves Performance

Just when we thought Quicksilver was no more, it turns out that several contributors are continuing occasional development over at social coding web site GitHub. Their latest release brought on some solid performance improvements, and it worked well (for us at least) with Snow Leopard.

Glims Turns Safari into a Browser Worth Using

Free Safari plug-in Glims adds a handful of new features to Safari, giving it the kind of features one might expect from a more, ahem, customizable browser—for those of you who still prefer Safari to its more feature-rich counterparts.

Popular Cross-Platform Apps:

Google Chrome—Dev Releases and Beta At Last

Google Chrome is just over a year old, but it's actually much younger for Mac users. We got our first glimpse at Chrome on OS X back in April, and it wasn't until last week that Google released the first beta for Macs. Be sure to check out our power user's guide to Google Chrome if you're just getting started.

Namebench Helps You Find the Fastest DNS Server for Your Computer

Google very recently announced a free DNS service they boasted as fast, but rather than take their word for it, we pointed you toward namebench (and several readers also pointed toward the excellent DNS Name Server Benchmark). It tests various popular DNS servers to find what's really going to be the fastest choice for your system.

Google Earth 5.0 Released, Looks Incredible

We're sort of junkies for maps and 3D, so when Google Earth 5 was released, we were pleased as punch. The update featured historical imagery, ocean maps, and improved world touring capabilities. Maybe we just like saving ourselves some dough in these tough economic times with a little Google Earth sightseeing.

And Then There Was Firefox

The notorious Firefox memory slow-downs may have some of us down on the reliable old 'fox, but that doesn't mean we aren't all still eager to grab the latest and greatest releases and stick with it as our default browser—whether it's the big Firefox 3.5 release or the Firefox 3.6 beta (1, 2, 3, or 4). We're looking forward to more great Firefox'ing in 2010.

Thunderbird 3 Officially Released with New Features, Improved Look

Sure it was two years since Thunderbird's 2.0 release, but at least they didn't disappoint. Thunderbird 3.0 comes with solid new search and filtering tools, better looks, and a great new tabbed interface.

HandBrake Updates to 0.9.4 with Over 1,000 Changes, 64-Bit Support

Free, open-source DVD ripping and encoding tool HandBrake released a pretty saucy update last month with a ton of fixes and improvements. It's no coincidence that it's always been our readers' favorite video encoder, and this year's big-ish (but still not 1.0) update should only help keep it there—even though several users aren't thrilled that the HandBrake devs have dropped AVI/XviD.

Now, because we like a good polling:

Airlock is a system preferences pane. Double-click to install it, associate it with your iPhone or iPod touch, set the security range, and that's it. I tried with my iMac 24 and my iPhone and it worked perfectly. You can even see a radar screen showing the distance between the two devices. The moment I stepped out of the limit, the screen locked. And then, as soon as I came into the perimeter, it unlocked automagically.

There is only one problem: If you use a wireless mouse or keyboard, it won't work due to a Bluetooth bug in Mac OS X. Otherwise, this thing will make you feel like James Bond.

Without the Aston Martin. And the Martini. And the laser watch. And the Scottish accent. And the hot girls. OK, so it won't really make you feel like James Bond, but come on, get on with the program here. [Airlock via Unplggd]

Teo en Ming, the ChromiumOS64 project lead, says of the download:

"The original Chromium OS project does not support 64-bit platforms. This is because the majority of the netbooks in the market are based on Intel Atom processors, which are mostly 32-bit."

With Chrome OS launching properly at the tail-end of 2010, we've got a full year to wait before we see anything more solid become available. And even then, it'll only be available on Google-branded devices, with Acer hoping to launch the first official netbook running it.

Let us know how you get on with the 64-bit Chromium browser below. [ChromiumOS64 via TechRadar]

Supposedly the pop up prompt (which apparently doesn't do anything) was seen by the fellow's coworker who explained the situation:

He believed he was in a temp-to-hire position, and after three months of extra hours and butt-kissing, turns out it's just a temp position. He was a good worker too. I'd have recommended him. Too bad he burned his bridges... Obviously he had contemplated quitting long enough to make this thing, but still refused to speak to anyone about his feelings. Ironically, he complained about the 'divas' at his last job.

Well, who'd want to keep him if he makes an app with prompts that don't even have functional buttons? If nothing else, one of the buttons should've opened an email app with a pre-written apology note. [Method Shop via Cult of Mac]

Microsoft may have backed out of the show's live special, but Family Guy definitely has the geek cred thing down. [Nick McGlynn]

It's a painting replica, painted with acrylic on top to make it look half-baked, then fitted with an electromechanical rotor that spins the infamous Mac OS X beach ball on top of it. Oh you clever James Theophane you. [Painting Crash via Make]

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:

I hate to say this about one of our own, but his comments were inaccurate and uninformed.

Youch. That's gonna be a fun day at work tomorrow for ya, Simon. [Windows Blog]

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]

You can download the Orb application right here. You'll have to look for porn to stream on your own. [Orb via Engadget]

Of course, you can argue that Windows is not as optimized as Mac OS X in that machine. On the other side, Apple's Intel-based hardware is really not that special. This shows in the gaming test, where Call of Duty 4 squeezes 5 more frames per second in Windows 7:

In other tests, however, Snow Leopard consistently beats Windows 7 running on this machine. Especially painful is the battery life test:

This one, however, can really be attributed to bad drivers, since the author of the tests says that he "was able to get just around an hour and a half with Windows 7 with general usage on the same machine" running Boot Camp 2.1 instead of the 3.0 version he used for the test. [CNET]

Documentation on the problem is still thin, and Apple hasn't issued any kind of response, but until this gets sussed out, you should probably cut back on the guest logins, lest you lose everything you've ever saved to your Mac, ever. Any new operating system has bugs, but if real—and it's starting to look that way—this one is pretty atrocious.

We'll keep an eye on this, since the more exposure it gets, the more likely people are to come forward with their own personal horror stories. Post 'em if you got 'em, in the comments. [ITWire via Neowin]

As a result of the individual motions by both companies, two hearings have been set for November 12 to determine whether there'll be a January trial. I'm not-so-secretly hoping that Judge William Alsup will look at the "user license agreements for both Mac OS X 10.5 and Mac OS X 10.6," arguments about Digital Millennium Copyright Act, and the whole disc protection circumvention mess and make Apple and Psystar duke it out in court. Hell, I'll volunteer to transcribe the case for everyone's entertainment, stupid argument by stupid argument. Just make it happen. [AppleInsider via Crunch Gear]

The Dock may not be perfect, but with the new Exposé in Snow Leopard, I think it is quite better than the task bar. And even while both are clumsy, I don't think paying $15 for uBar—which is 32-bits, and crashes badly in Mac OS X 10.6—is the solution. However, if you are into bondage, domination, sadomasochism, and the whole "Start" menu thingie, this is your funeral, kiddos. [Brawersoft]

Kahney argues that the "new" virtual keyboard, and Exposé in the Dock are signs of preparation for an Apple tablet:

The more I play with Snow Leopard, the more it looks like it's designed to run Apple's upcoming tablet.

However, there are simpler explanations than these conspiracy theories (without even entering into the debate of iPhone OS—the most likely candidate for a 10-inch tablet—vs Mac OS X. Clumsy desktop operating systems don't translate well to slates, as Windows has demonstrated many times).

The virtual keyboard has been in Mac OS X forever, as part of the input system. In fact, it was part of the old Mac OS as well, and was incorporated as part of the input menu system in Mac OS X. In Snow Leopard, you can activate it using the Keyboard panel in System Preferences. Go there and check "Show Keyboard & Character Viewer in menu bar."

Before, the keyboard window used to be so tiny—as you can see in the top image—that it even made people whine about it in Apple support forums. Fortunately, Apple changed this, and now you can resize the window as much as you want.

There's no magic here. It's just a vector-based app that can be scaled at any size you want. The same happens with the Character Viewer.

So, if this is not a sign of the tablet, what could it be? Apple has been working on a fully resolution independent display model since Mac OS X 10.4. During every Worldwide Developers Conference, Apple has been preparing developers to ready their apps for the jump. Mac OS X 10.5 Leopard implemented a system wide resolution independent model (unfortunately, it was systemwide, and not on a per-screen basis).

The objective: To be able to use ultra-dense resolution displays without making everything on the screen tiny. As a user, if Apple decided to turn on this feature, you would see that menus, icons, and buttons use the same physical space now matter what display you use. Things would have the same size but would look sharper on a display with more pixels per inch. Example: A button will be one inch wide in a 24-inch 1080 pixel-wide display, and a 24-inch 2160 pixel-wide display. However, it will look a lot sharper on the 2160 pixel-wide display because it will be made of more dots.

If you have the developer tools installed in your Mac, you can check the scalability of the user interface using Quartz Debug. This tool allows you to zoom in and out the user interface, seeing how everything—except bitmap elements—scales in real time, with no pixelation.

What about Exposé on the Dock? I'm a believer in Occam's razor theory: The simpler theory is always the better. In this case, Exposé on the Dock is just a more convenient way to see your open application's windows. More intuitive and easier to use for the normal user than hot corners or function keys.

Bottom line: I've no doubt that touch interfaces will come to Apple devices, but these two functions are not any indication of it.

Gallery haters take note, clicking here will take you to a giant list of the tips.

[Back to our Complete Guide to Snow Leopard]

Sync Contacts with Gmail and Yahoo: No longer just for syncing with the iPhone and Mobile Me, the Contacts app can now talk to your Yahoo and Gmail address books, and pull down your contact info. It's as simple as going into Contacts preferences and hitting the Accounts tab.

Show Date In Menu Bar: If, like me, you're too lazy to click on the clock, or launch widgets, or just make use of your God-gifted memory, you can now set the clock to display full date in the Menu Bar, just go into Date and Time Preferences and adjust.

Smart Text Formatting and Correcting on the Fly: Snow Leopard has a number of text-based enhancement for apps like Text Edit, iChat and Mail including spelling auto-correct, and text substitution, which lets you use shorter macros in place of longer words and phrases. The spell corrector is limited to commonly misspelled words, but the text substitution is yours to define. Just control-click in the text entry field for any of the aforementioned apps to toggle the features on or off, and visit the Text section of the Language & Text system pref for tweaking.

Password Log-In Delay: If you have password protection enabled for when your computer goes to sleep, you can now choose how long your computer snoozes before the password requirement actually kicks in. This means you can more easily have the privacy of a darkened monitor without the pain of having to key in your password every time you step away. These settings are under the Security preference pane.

Google and Yahoo Support in iCal: iCal is now much easier to add calendars from Google and Yahoo. No hacks or third-party software necessary. You just add a new account under preferences and select your service of choice. (Suit-wearers take note: Exchange support is here as well.)

Edit Videos in QuickTime X: QuickTime Pro users have long been able to edit and convert videos without launching the heavier movie apps. With QuickTime X, Apple has done away with that nasty fee. Yep, Pro is dead. Now everyone can trim and save, with a visual navigation timeline for easy edits, not to mention that other pro perk, viewing movies in full-screen.

Upload to YouTube From QuickTime X: Now you can upload directly to YouTube from QuickTime X. Just open any video file then go up to the menu bar and click Share. That same menu lets you upload movies directly to MobileMe, and convert movies to iProduct-friendly formats to send to iTunes.

QuickTime X Video Capture: How much do we love QuickTime X? It now also has video capture direct from the iSight camera, any FireWire video camera or any audio input. Better still, it can record the action happening on your screen, and save that as a movie too. A riveting one, to be sure.

Smarter Drive Eject: Half bug fix, half user enhancement, Snow Leopard now tells you exactly why it can't eject a drive that's in use. Instead of saying it's just busy, it tells you what app is using it. Apple also promises ejecting in general is just "more reliable."

Recover Trashed Files: If you accidentally sent an item to the trash that you want to replace, you don't have to go in and then drag it to wherever you had it before (if you even remember). Now you just control-click on the trashed item and select "Put Back." Problem solved.

Airport Signal Strength: Windows users have long been accustomed to this, but when you're looking for free wi-fi to steal and wanna get an idea of what's most reliable, you can now get an idea before you connect. It really took Apple this long to add this?

Automatic Time-Zone Detection: If you're jet setting around the world with regularity, you can allow Snow Leopard to detect your location using Wi-Fi hotspots, and adjust the time zone—and clock's time—accordingly.

Preview a File Inside Its Icon: If hitting the space bar for a "quick look" is too much for you, try the in-icon previews. Just roll your cursor over a video or audio file and a play button will appear. PDFs show arrows, letting you leaf through their pages. In most folders, there's a slider that lets you scale icons up to a massive 512x512 pixels, presumably to make this file preview seem in any way rational.

Annotate This!: The increasingly useful Preview now has a bar at the bottom of the window full of various annotation tools, such as shapes, highlighter, memos, underline, strikeout and hyperlink. Useful for the bookworms out there who are deal with texts in digital formats. Perhaps it also hints at the Apple Tablet's Preview app, because a device that goes up against a Kindle would need something like this (along with, you know, a five-day battery life).

Chinese Character Input: This isn't really a feature the majority of us will use, but rather a demo of what's possible with Apple input technology. You can use the trackpad to write Chinese characters and have them appear as computer text, just hit Ctrl-Shift-Space Bar. Pretty neat idea, and perhaps something else that might come in handy with a tablet.

There are, of course, even more tricks and new features. If you have any good ones you want to share, you know how to do it.
