Bluetooth LE Adapters Do Enable OS X Yosemite’s ‘Handoff’ on Older Macs

Sometimes macrumors aren’t completely right

Bluetooth LE Adapters Don’t Enable OS X Yosemite’s ‘Handoff’ on Older Macs

My 2008 MacPro (so old) has a wifi card from some new imacs/mbp installed with adapter to mini-pcie slot. It gives me 802.11ac AND bluetooth 4.0, no need to remove old bt card, as new one is preferred over old one.

Continuity is supported:

P.S. got this nice things from MacVidCards.

Little Teaser

go here

OSX 10.10 adds support for Radeon R290X

R9 290X works out of box, R9 290 will need few dev-id injections, to AMD8000Controller and AMDRadeonX4000.kext

You can enable it partially in OSX 10.9, 2d only mode, with output and res change but without acceleration/3d

copy these kexts from 10.10 to 10.9

AMD2400Controller.kext
AMD2600Controller.kext
AMD3800Controller.kext
AMD4600Controller.kext
AMD4800Controller.kext
AMD5000Controller.kext
AMD6000Controller.kext
AMD7000Controller.kext
AMD8000Controller.kext
AMD9000Controller.kext
AMDFramebuffer.kext
AMDSupport.kext

For OSX 10.10 on hacks

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/
