Apple on Wednesday evening released another round of software updates targeting its just-released line of iMacs, the existing line of Mac Pro systems, and its Boot Camp dual-boot software.

iMac Software Update 1.0

iMac Software Update 1.0 [5.1MB] provides important bug fixes and is recommended for 20-inch and 24-inch iMac models with 2.0, 2.4, or 2.8GHz processors.

Mac Pro SMC Firmware Update 1.1

Mac Pro SMC Firmware Update 1.1 [544KB] adjusts fan behavior in the Mac Pro.

The updater application will be installed in the /Applications/Utilities folder and will launch automatically after restart.

"The SMC firmware update starts automatically. A status bar indicates the progress of the update," Apple says. "During the update your computer fans will run at full speed, but will return to normal once the update completes."

Boot Camp 1.4 beta

Boot Camp 1.4 beta [347MB] contains several updates and is intended for all new and previous Boot Camp beta users.

Among the features Apple lists for the new version are support for keyboard backlighting, Apple Remote pairing, updated graphics drivers, improved Boot Camp driver installer, improved international keyboard support, and localization fixes.

However, it should be noted that several of these fixes were listed for previous versions of Boot Camp, meaning the new version may simply employ overall stability and performance enhancements.

iMovie 6 as a standalone download

Apple on Wednesday also posted a version of iMovie 6 HD [154.6MB] for adopters of iLife '08 who'd rather use the previous version of iMovie.

"iMovie HD 6, previously distributed with iLife ’06, is available for download for those who have purchased and installed iLife ’08," Apple wrote.
