I have a Macbook Pro 11,1 (MBP 13" - 2013 with retina display), which is used by my father for simple tasks. It was working with Ventura for a long time and later I've updated it to 15.6.1. Somehow the computer is slower than my expectation, even though the device has 16 GB RAM unda 512 GB SSD. I have performed the root patches maybe 3 times.
While I was checking it with SilentKnight, I realized the firmware version is older than the most actual one:
Mac model MacBookPro11,1
EFI version found 432.60.3.0.0
expected 478.0.0.0.0
❌ Need to update EFI firmware.
I don't know why I missed this, because I updated it before to highest version, but I cannot remember in detail.
Long story short: Is there any way of upgrading the firmware without installing High Sierra once more? I always carry my OCLP harddrive with me, but this time I have no stick or HD to install this. Or do you have any recommendation for the OCLP settings?
