Hi everyone,
I'm hoping someone here can help – I've been running into a frustrating issue since updating to the latest version of OpenCore Legacy Patcher (OCLP). Since the update:
- My MacBook (Model: MacBook Pro - Retina, 15", Mid 2014) is overheating
- The battery is draining rapidly
- I wanted to apply the new root patches, but the patching process fails with:
Failed to mount root volume
Error 75 – "mount_apfs: volume could not be mounted: Resource busy"
What I’ve tried:
- Tried applying patches via OCLP GUI – failed.
- Manually tried
sudo diskutil mountDisk disk1s4– says Success , but nothing actually mounts in Disk Utility. - Verified patching capability – OCLP confirms it's possible.
- Full log output below.
Full error log:
- Starting Patch Process - Determining Required Patch set for Darwin 24 Pulling metallib list from MetallibSupportPkg API No direct match found for 24C101, falling back to closest match Closest Match: 24C100 (15.2) metallib already installed (15.2-24C100), skipping - Verifying whether Root Patching possible - Patcher is capable of patching - Mounted Universal-Binaries.dmg Failed to mount root volume Subprocess failed. Command: ['/Library/PrivilegedHelperTools/com.Dortania.OpenCore-legacy-patcher.privileged-helper', '/sbin/mount', '-o', 'nobrowse', '-t', 'apfs', '/dev/disk1s4', '/System/Volumes/Update/mnt1'] Return Code: 75 Standard Output: mount_apfs: volume could not be mounted: Resource busy mount: /System/Volumes/Update/mnt1 failed with 75 Standard Error: None Failed to mount root volume - Failed to mount root volume, cannot continue with patching!!! My questions:
- Has anyone else experienced this exact error when trying to patch the root volume?
- Could downgrading to OCLP 2.3.2 and reverting root patches work as a last resort?
- Any known workarounds to resolve this "resource busy" issue?
Thanks so much for reading – I’d really appreciate any advice 🙏🏼
