How to Diagnose Touch ID data gets erased after a long shutdown After an OCLP macOS Upgrade
Power, battery, Touch ID and trackpad behaviour after OCLP upgrades is usually firmware, SMC or root-patch related.
Step-by-Step Fix:
- Back up first: Make a Time Machine backup or clone before changing OpenCore, EFI, root patches, or macOS versions.
- Reset low-level state: Reset NVRAM/PRAM, then perform the correct SMC reset for the Mac model.
- Re-apply patches: Open OpenCore Legacy Patcher, run Post-Install Root Patch, reboot, then test again.
- Check hardware health: Review cycle count, battery service status, trackpad settings and Apple Diagnostics before blaming macOS.
- Compare with a supported OS: If the issue is critical, test Monterey or the last officially supported macOS to rule out failing hardware.
Final check: Change one thing at a time, reboot, and keep a copy of the last working EFI before the next test.
Original Question: "Touch ID data gets erased after a long shutdown."
Hey. Im facing a specific issue and was wondering if anybody has a solution for this. I just recently updated my MBP 2017 15’ to macOS 14.8.7 and when i start it after a good few hours my registered fingerprint is gone and i have to register it again and it works fine again before the same thing happens.
