Should be a no-brainer on most machines. Should work OOB on C2D/C2Q/Arrandale systems. Sandy/Ivy Bridge systems will need to re-instate 10.10.3 patched AICPUPM kext to avoid KP (or use null CPUPM). Haswell systems will need the patched kernel. As usual, this applies to Chameleon-based Hackintoshes, Clover-based models being able to call on built-in on-the-fly patches.

 

Great news for SSD owners: 10.10.4 introduces a feature to enable trimming on non-Apple SSD, at last!

sudo trimforce enable

That's it, that's all, SSD trim patch can now be considered a thing of the past.  :)

It's been totally safe to update through AppStore for quite some time.

 

Now, bear in mind the eventual and/or usual safety measures:

  • on Sandy/Ivy Bridge platforms with Chameleon, reinstate NullCPUPM before reboot as AICPUPM will need rematching to avoid KP
  • on Haswell platforms with Chameleon, patched kernel will be required to avoid KP/reset
