For OSX 10.10 on hacks

June 02nd 2014 Posted to OSX 10.10

Few notes from release  notes.

In Developer Preview 1 unsigned or improperly signed kexts will not be loaded. To use unsigned kexts during development, this strict check can be disabled by adding a “kext-dev-mode=1” boot arg.

Installing kernel extensions on systems running Developer Preview 1 may make your system un-bootable. To fix the issue, boot into the Recovery Partition and run the following:

touch /Volumes/OSX10.10/System/Library/Extensions
kextcache -u /Volumes/

    Hello,

    I tried your boot arg using clover but same result, i can’t reach install screen, stuck on grey/white screen with mouse

    Maybe my hack is badly made ?

    I cannot find mach_kernel in the Yosemite install app. Tried to create install USB without it but the installation would stop complaining that can’t find mash_kernel. At the same time I noticed that Yosemite on a genuine iMac does not have mash_kernel in the root directory while Mavericks has it!?

    Misha, use Clover, it doesn’t require kernel file, and will let you to install and use Yosemite. The only problem is that FakeSMC kext can’t be loaded within installation, and it’s required to load it manually from console.
