What We Know About OS X Yosemite so far...OS X Yosemite is one of the biggest changes to OS X in a long time. Besides new features, redesigned icons, and a new system font, there are a few things that are functionally different this time around. Here is a partial list of things to know before attempting an update or a fresh installation.
- The location of the OS X system kernel has changed from /mach_kernel to /System/Library/Kernels/kernel.
- Any patched or unsigned drivers installed to /System/Library/Extensions/ now require a special boot flag to load: kext-dev-mode=1
- 9 Series motherboard quick fixes for audio and graphics are no longer necessary.
- Mobile HD 4600 Device IDs have been removed. Patched drivers or ID injection is necessary.
- Older systems with AWARD BIOS may need to roll back AppleACPIPlatform.kext to the 10.9.5 version. This includes all 6 Series and X58 Gigabyte motherboards.
Our tools will be available shortly- stay tuned!
