A computer problem starting right after a Windows or macOS update, a new peripheral or a software install should be checked against that specific change before a factory reset. For Mac unexpected restart or kernel panic, first record the panic string, disconnect peripherals and test in safe mode.
What this covers
- Mac unexpected restart or kernel panic with this exact failure state
- Diagnosis across third-party extension/peripheral versus macOS, memory, storage and logic board

0 of 4 completedCapture the exact failure state
ReversibleNote the exact update version or newly installed software, and confirm the prior working state. Expected behavior: remain stable under normal workload without a panic report.
Isolate the component boundary
ReversibleRecord the panic string, disconnect peripherals and test in safe mode. Uninstall the new software or roll back the update in a controlled test, where the OS supports it. Boundary to separate: third-party extension/peripheral versus macOS, memory, storage and logic board.
Correct only the proven cause
ReversibleUpdate/remove the proven software or run Apple Diagnostics for hardware. Apply the vendor's fix for the update, or reconfigure the setting the new software changed.
Verify and stop safely
ReversibleConfirm stable operation with the update or new software present for one full session. Back up immediately after repeated panics, heat, liquid or storage errors.
