Failed update from 14.3.1 to 14.4

Hi there, I have an issue with my hackintosh but honestly I don't even know if it's an issue with my build or an issue with macOS itself in general.

I've tried updating from macOS 14.3.1 to 14.4 via OTA but when it restarted into the macOS Installer, it just rebooted after still on 14.3.1, I've tried installing the update via full installer pkg but same result.

Not only it didn't update, but now I have the "macOS Installer" on my Opencore bootloader and can't get rid of it.

I didn't have any kernel panics or errors, it just rebooted back to the previous version.

Do you know how to "clean" all the update files without resetting the whole pc? I do have backups in case anything happens but it would be a pain to reinstall everything...

The plist of that the update left says this:

<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>BootUUID</key> <string>EE57FC15-6128-474E-81D2-9BE82466B3E9</string> <key>PreviousRestoreDate</key> <date>2024-02-02T12:25:06Z</date> <key>PreviousUpdateDate</key> <date>2024-03-08T18:37:09Z</date> <key>PreviousUpdateState</key> <integer>2</integer> <key>ota-failure-reason</key> <string>MSU 1130 (Failed to verify against canonical metadata);NSPOSIXErrorDomain 13 (img4_firmware_execute failed);;1</string> <key>ota-result</key> <string>MSU 1130;exited</string> </dict> </plist>
