Thank you for helping me solve the problems caused by the system upgrade.
After Mac pro 5.1 (MD770) is upgraded from Sonoma to Sequoia15.1.1, there is no keyboard and mouse at boot, no boot disk can be selected independently, and no Bluetooth after entering the system. The system displays that Bluetooth is disabled and cannot be turned on.
Also, system Bluetooth cannot be turned on when upgrading Sonoma. After resetting the PRAM, Bluetooth is turned on automatically. No keyboard on now. PRAM cannot be remastered.
The OCLP is 2.1.2
