I have a late 2013 MacBook Pro, and I installed OCLP so I could install macOS sequoia. I managed to install Sequoia, but got greedy and I updated to macOS 26 from the system settings. I restarted the computer and I can see it’s macOS 26 but my mouse is locked in position in the upper left corner of my screen, and I cannot type my password because the keyboard is blocked as well. I tried, to reinstall macOS sequoia using the EFI, but after he accepts my request to install macOS Sequoia, he asks me where do I want to install it, and I cannot install it on the disk because of an error (photo). I’ve tried with Internet recovery, but it won’t install macOS X, so I can’t go back. Is there a way to save my Mac or do I have to erase the disk and try again (I really would not want that unless strictly necessary). Is there a way to save the disc? Is there a way to unblock my mouse and keyboard in the macOS 26 loading password page?
