Apple has released new MacBook Pros, with the new Sandy Bridge processors and Thunderbolt connectivity. Early reports indicate that they are much faster than the previous generation machines -- to the point where the new baseline 13" model matches or betters the old 17" model on many speed and performance tests.

It has been revealed that Mac OS X Lion will drop Rosetta, a software abstraction layer which provides support for PowerPC binaries on Intel machines. This is an interesting move that some are labelling premature, as, on the one hand, it forces developers to get their code up to modern standards, but, on the other, it breaks compatibility with some professional software still actively in use. Some of the other features slated for Lion are looking promising, though.

At a media event on Wednesday, Apple announced a second-generation iPad, complete with a processor upgrade (the iPad 2 sports a 1GHz dual-core A5 processor), front- and rear-facing cameras, Smart Covers, and an option to get it in white colour. The new iPad models will be available in the US from March 11, and in other countries over the following weeks. In the meantime, you can pick up the first-generation iPad at a discount.

Also announced at the event was iOS 4.3, which features some useful enhancements to AirPlay, allows iTunes Home Sharing, improves performance in Safari, and offers the long-demanded iPad side-switch preference (rotation lock or mute). It will be available from March 11, and is compatible with iPhone 3GS, iPhone 4 GSM, 3rd-gen iPod Touch, 4th-gen iPod Touch, iPad, and iPad 2 (I guess that means iPhone 3 and 2nd-gen iPod Touch owners should upgrade now).

We've had a quiet month in Mac emulation news, but there were notable updates to VICE, Dapplegrey, and gbpablog, amongst others. Hit the jump for details on these and other minor emulator updates, as well as a couple of Mac gaming tidbits.

Parallels Desktop 6 for Mac is now available. The new version boasts enhanced performance, remote access via iPhone/iPad/iPod Touch, easier setup, up to 80% faster 3D graphics performance, and Surround Sound 5.1 support, amongst a wealth of other features. Check out the official website for more information.

Java-based PSP emulator JPCSP has made considerable progress in recent months, with the latest release (0.6) offering a host of new features and major improvements. The developers boast compatibility with more than 70 games (commercial and homebrew). See the release notes for full details on the update, and the homepage for more information about the emulator.

Quickfire updates have been released for DOSBOX front-end Dapplegrey, which is now at version 2.16. Changes include more freedom to choose which DOS executable file to use when starting a game, in addition to a few related tweaks to the interface and behaviour.

An alpha build has been released for Macintosh Plus emulator Mini vMac’s upcoming 3.2.1 update. Described by the developer as the “netbook edition,” the update promises more accurate timing in CPU emulation, while a new feature called “AutoSlow” allows users to conserve battery power by reducing the emulation speed to 1x when no input or output occurs for two seconds. See the Mini vMac website for more information.

More updates after the break.

Apple has released the Magic Trackpad, a multi-touch trackpad designed for use on desktop computers. It has a size and profile that matches Apple’s most recent keyboards. Priced at US$69, many have labelled the device too expensive, while others wonder if it is the beginning of a paradigm shift away from mouse input. Check out the MacScene forum thread for the community’s take, and see the official product page for more information.

Valve plans to give away some of their code for OpenGL on the Mac in order to accelerate and motivate further development of Mac versions of Steam games. They claim that this will eliminate the “real hard work” in putting games on the Mac.

Apple announced an update to the iMac line, with speed bumps and a move to discrete graphics cards across all models. They also introduced a new Mac Pro line that promises “up to 50 percent greater performance,” and a 27-inch LED Cinema Display, which will replace the existing 24-inch and 30-inch models. The new Mac Pros will be available “in August” while the Cinema Display is set for a September release.

Apple’s Q3 earnings revealed that the Mac is growing in popularity, despite the recent focus on iOS devices. The iPad has already sold more than 3 million units. The iPhone 4 sold over 8 million units despite its much-publicised antenna problems and limited international release.

Emulator updates after the break.

Leading digital distribution platform Steam finally made its way to the Mac on May 12, with around 50 launch games. The Mac Steam library now includes 96 titles, including newly released ports of Half-Life 2, Torchlight, and Portal. Check out the MacScene community’s reaction here, here, and here, in addition to a Portal-specific thread here.

As proof of a drastically changing tech landscape, Apple’s market capitalisation surpassed that of Microsoft last week, making it the largest technology company in the world. This marks one of the most incredible turnarounds in any company’s history, with Apple having been all but dead back in 1997, when Steve Jobs returned as CEO. Don’t celebrate too soon, though, because the happy folks at Microsoft are still way ahead on revenue.

In exciting news for Amiga fans, a new emulator called PUAE has been released. PUAE merges Richard Drummond’s E-UAE 0.8.29 with the latest version of WinUAE, and is available for Unix-based platforms. You can download the latest version from here, or check out Ultimate Amiga for more information.
