Does anyone know what the original OEM SSD hard drive for a mid 2015 15-inch Retina MacBook Pro (model identifier MacBookPro11,4) is, and how I can buy a used one, and/or how to fix the error in Terminal I'm getting while trying to manually upgrade the firmware?
I'm trying to upgrade from Mac OS Catalina to Monetery because GoodNotes on my Macbook stopped synching with it on my iPad because the version on my Macbook is too old, and I can't update it because Catalina is too old. I can't currently can't upgrade to Monterey because the person who we bought the computer from swapped out the original OEM SSD hard drive for a third-party SSD drive, so the OS won't update the system firmware and install Monetery. We do not have the original hard drive. I tried this workaround here to update the firmware despite the third-party drive, but haven't been able to get it to work. I am attaching the readout from Terminal I am getting currently when I try to update it in case anyone here can decipher why the firmware is still not updating.
If I can't get the firmware to upgrade manually, then my next step is to try to buy a used "original" OEM hard drive for the laptop and reinstall that temporarily so that I can update the firmware. Does anyone know what the original OEM SSD hard drive for a mid 2015 15-inch Retina MacBook Pro is, and how I could find one that the system will recognize as the original, without paying an arm and a leg?
