A small EFI update for the MacBook Pro is available from last night (firmware update 1.5.1, 4.9 MB).
The narrative is exactly the same as the previous 1.5 update dated 15 days ago, with fixes of various problems and offering greater stability, as well as the same ROM versions (the support page of the 1.5 version has been deleted) .
This update fixes various problems and improves the stability of MacBook Pro computers.
Once the program is applied to your Mac, your BootROM version will be as follows:
MBP21.00A5.B08 or MBP31.0070.B07
You can confirm the BootROM version installed on your computer using System Information.
The CD restoration program to reinstall the original firmware moves to version 1.7 (22.5 MB).
