On November 13th Apple released a handful of updates, most having to do with Boot Camp, sleep and wake-from-sleep issues with its Intel-based Macs.
According to Apple, the EFI Firmware updates “fix several Boot Camp, start up, and wake-from-sleep issues” for the Mac Mini, MacBook, MacBook Pro, and iMac.
The EFI Firmware update for the Mac Pro “This EFI Firmware Update fixes several Boot Camp and start up issues.”
Please read Apple’s instructions carefully for the EFI update that corresponds to your computer, and also prepare yourself with a Firmware Restoration CD in case you have issues while updating your firmware.
Apple also released Digital Camera RAW support & fixes for both PPC and Intel-based Macintosh computers running Mac OS X Tiger Client or Server, and an update to it’s X11 package, X11 Update 2006 1.1.3, which “addresses several issues in the X11 for Mac OS X package, enabling it to better handle GLX stereo visuals and offscreen rendering to GLX Pbuffers and Pixmaps.”
As with any update for your computer, backup all important data prior to the update, and remove any third-party devices connected to your computer. Make sure your Mac is connected to a power source, and do not interrupt, restart, or shut down your computer while the update is being applied.
