10.10.3 brings better support for 5k

Before 10.10.3, to get 5k dell display to work one needed to have nvidia videocard with two display-port outputs, special boot option and powercycling of display after bootup was needed.

since 10.10.3 there is no more need for last step (powercycling display). Your 5k display will boot straight into 5k desktop.

10.10.3 brings 5k support to 2013 MacPro, there is no bootscreen tho. No special bootoptions needed, just plug and play, just no bootscreen.

As for nvidia, you can have bootscreen there, mac edition of gtx9x0 needed (or titan x, gta v is coming).

Dell 5k’s display have two inputs, one is single DP link for 4k output, another one is double DP link for 5k. Connect all three into card, you will have bootscreen in 4k and desktop in 5k.

If OSX 10.10 update fails for you…

With next message:

“This partition map modification would make a windows partition unbeatable”

It means that some Apple programmers are lazy dumbasses.

Here is how to fix it: you need to backup current mbr on your OSX drive, remove any partitions in mbr except the first one with type EE (so disk will look like pure gpt disk). Install osx update. Then restore mbr from backup. Then show middle finger to Apple (it’s not that hard to fix for lazy apple programmers)

you can do it with gptsync or with fdisk and dd.

It happens because of missing recovery volume. I miss recovery volume because I had to restore osx partition from TM backup. HFS+ isn’t that great and can be easily crashed with few resets.
P.S. it’s all for MAC, not HACK (even tho hacks ccan use that way too). Owners of genuine Macs have to mess with it. It’s shame !

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.

OSX 10.10 adds support for Radeon R290X

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/
