OSX 10.10 DP3 and handoff

After installing OS X Yeti DP3 one may notice information about handoff&continuity is now missing from sys profiler.
However it appears in sys preferences app now. Still enabled here on mp3,1.

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

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/

Slow Radeons 7xxx+ on MacPro3,1

It’s known for a while that GCN radeons are low performers on 2008 MacPro using OSX 10.9

And the reason for this is…..

AppleIntelCPUPowerManagement.kext

Apple fucked up some CPU power management resulting in videocard not running properly. plz fix.

Just remove AppleIntelCPUPowerManagement.kext and AppleIntelCPUPowerManagementClient.kext if you like to workaround it, speedstepping still works, cpu isn’t hot/cosuming a lot, still drops the clocks.

 

Fuck you AMD!

Wanna use AMD and nvidia card in one system, AMD says no.
wanna use radeon 2600xt (uses legacy driver) and modern videocard in one system? AMD says no

AMD has the worst driver programmers I ever saw. To be able to have two different display drivers running in one system is just too hard for their small retarded minds. Every driver release gets worse. fuck you AMD!

Efi bootloader for 32-bit efi macs and osx mavericks.

Hello. It’s a bit old, but still awesome news. An osx bootloader for old macs with 64-bit cpu but 32-bit efi (like macpro 1,1/2,1). Can boot osx mavericks, supports efi in osx, so nvram, firevault and other things depending on efi runtime calls will work.
