Prepare a bootable installer flash drive for MacOS Monterey completely on Windows? Hi,
I still have the old flash storage in hand I it will help. I don't mind doing restore to my Mac if necessary, I already did that a couple weeks ago and reinstalled macOS so he pretty much wiped out.Ģ. I attached screenshots of anything that I could come up with to help you help me😉:ĭiskutil list commend, Hardware system report, Software system report, disk utility, about this mac.ġ. Running FirstAid on my SSD (on all the sub disks) was successful and didn't come up with anything. I saw a way of doing a firmware restoration/restore with Apple Configurator 2 (not even sure if that what I need), but I don't have access to another Mac to try doing that.
#Macbook pro retina efi update update
When I clicked the about on the macOS update assistant it says OS X Mountain Lion/ Lion, which make no sense because my MacBook shipped with El Capitan/Sierra.įrom a little research that I did, I think (but I am surly not an expert) it has something to do with me having no Recovery partition + no EFI Boot ROM, after replacing my SSD. In the beginning its seams ok, turn on and off doing the apple logo loading time bar, but a the end it failed saying my internal storage is not compatible. Then, I tried update via the recovery mode (which I only have the internet one), but he wanted me to reinstall macOS Big Sur, not updating to Monterey.Īnd finally, I tried via USB bootable installation.
