WindowServer and Kernel Panics and Graphics Issues on macOS Sonoma - Need Help Diagnosing
Device and macOS Details:
MacBook Pro 2019 (Model: MacBookPro15,1)
macOS Version: Sonoma 14.7.1
GPU Details: Intel UHD Graphics 630 and Radeon Pro 555X
The Problem:
Frequent WindowServer & Kernel Panics: Occur during active use or after waking from sleep.
Screen completely freezes, cursor moves but no key combination achieves anything.
Have to restart.
WindowServer High CPU Usage: WindowServer often consumes significant CPU resources.
Graphics Issues: Suspected conflicts between Intel and AMD GPUs.
Current Observations:
Runs fine in Safe Mode (extensions and login items not loaded).
Crashes frequently in Normal Mode.
High CPU usage from processes like WindowServer, VTDecoderXPCService, and apfsd.
Steps Taken So Far:
- Two thorough visits at the Genius Bar within the last 10 months have not fixed the problem.
- All diagnostics do not report any hardware problems.
- Fresh installation of macOS Sonoma.
- Reset the PRAM
- Reset the SMC - HOWEVER unusual behavior: computer restarts when pressing just the three keys (Shift + Control + Option). It shouldn't. Those 3 keys alone should just prepare the system for the reset when combined with the power button.
- Observed behavior in Safe Mode versus Normal Mode.
- Ran EtreCheck reports to identify problematic extensions and processes.
EtreCheck Summary:
Reports unsigned files, high CPU usage, and kernel panics.
Identifies residual extensions and system modifications.
Request for Help:
Am running out of things to try.
