Had my 4530s running smooth for nearly 2 years now.
Since 10.10.5 I am having graphic glitches and sometimes a freeze.
Already used latest PBI 6.4.2, repatched my DSDT, reinstalled Kexts, rebuilt cache, did EC resets.
Glitches keep coming back after few hours and I'm at my wit's end.:confused:
Any ideas where to look?
Thanks a lot!

Double check everything. Post EFI/Clover and ioreg if you need help.

Finally it turned out that updating the BIOS to F60 did it.
I still was running on F50 and didn't want to fiddle around on the system when it was running fine.

Thanx Rehab.

It was probably the ACPI re-patch after updating BIOS that fixed things.

Patched ACPI must always be in sync with native ACPI.
