Hello,
I have lost the ability to boot into Mac OS X.
This is a 2009 (?, used) MacBook Pro running OS 10.10, 11, or 12 (sorry) and Windows 10. (There are probably going to be a lot of palm-hits-forehead moments reading this post.) I've had it partitioned for four or five years. Yesterday I found I was no longer able to boot into Mac OS X at all.
The computer has always booted into Windows by default for reasons I can't fathom, but plays the Mac startup sound and presents the Mac blank grey screen before starting to boot into Windows. Naturally, I just hold Option to get into OS X. This no longer works. Neither Option nor any of the other startup key combinations (Cmd-R ...) I've tried has any effect, I'm not presented with a choice of drives to boot from, and the computer boots into Windows from the Mac blank screen as if I'd let it be without pressing Option.
Windows auto-updated yesterday and I didn't download, install, or do anything else unusual, so I believe the update must have broken this functionality somehow. I tried to revert the updates, but Windows wouldn't give me the option to revert three of them, and reverting the others didn't have any effect.
I tried resetting Windows (deleting programs, but not files), but that had no effect.
I plugged in an Apple USB keyboard to see if the keyboard was malfunctioning, but that had no effect.
I can't boot from an install disk because my disk drive is broken (has been since I bought it used). I don't own an external disk drive and am too broke to buy one (seriously). If the best option involves buying an external disk drive, please still let me know so I can follow up on that when I have money again.
This is not a perfect dual-boot installation. I partitioned my drive (with Windows 7) after Boot Camp was no longer supported, and had to follow some online instructions to access the utility. Because of either this or a failure to follow instructions, Windows has always run a little wonkily--as I said, it decided it would be the default OS, I can't change the screen brightness, the speakers sometimes can't find their drivers, the microphone often doesn't work. But I've never had a problem as severe as being locked out of Mac OS before.
Thank you for any insight you're able to provide.
THH
