After resetting the Mac I just bought from someone else, I could not install the macOS Monterey. I tried the normal recovery route and downloaded from internet and it failed. Then I created a bootable USB using a second Intel Mac I own, and it still fails with the same error: Mar 16 23:22:38 macbook-pro osinstallersetupd[217]: Apply failed: Error Domain=SUMacControllerError Code=7760 "[SUMacControllerErrorApplyFailed=7760] Failed to perform Apply operation: [MobileSoftwareUpdateErrorDomain(MSU):1041_1_RamrodErrorDomain:1014_2_MSUFirmwareUpdaterErrorDomain:3_3_MSUFirmwareUpdaterErrorDomain:3_4_MSUFirmwareUpdaterErrorDomain:3_5_MSUFirmwareUpdaterErrorDomain:-536870198]" UserInfo={NSLocalizedDescription=Failed to apply the software update.
