Hi everyone,
I’m trying to apply root patches using OpenCore Legacy Patcher, but I’m running into the following error and can’t proceed:
vbnetCopyEdit- Running sanity checks before patching - SystemVersion.plist build version mismatch: found 15.3.2 (24D81), expected 15.4 (24E248) An update is in progress on your machine and patching cannot continue until it is cancelled or finished - Unmounting root volume - Failed sanity checks, cannot continue with patching Please ensure that you do not have any updates...
What I’ve tried:
- Restarted the Mac – no change.
- Checked Software Update – it says there are no available updates, but apparently an update is still “in progress.”
- I’m not sure how to cancel or finish this pending update that’s blocking the patcher.
System info:
- macOS Sonoma 15.3.2
- Build: 24D81
- I’m trying to patch for better support on an older Mac (GPU-related issue).
- Using OpenCore Legacy Patcher.
Question: Has anyone encountered this error before? Is there a way to cancel or clean up the pending update so I can proceed with patching?
