Anybody know anything about this? I have some troubleshooting questions.
Late 2011 Macbook Pro 15-inch, Identifier 8,2. It has had the discreet (AMD) gpu disabled (dosdude1 did it). It had Catalina (unsupported) on it (up until 30mins ago), and I don’t even remember what method I used for that. Maybe a Catalina patcher (dosdude? don’t remember).
I heard about Open Core Legacy Patcher several months ago. Decided I’d try it out today.
I got pretty far into the process. But then got a window and error “an error occurred preparing the software update”. Only option was to click “OK”. Then I’m at “Choose startup disk” window - but I erased my SSD during the prep/earlier stages (the main drive, the one that had my Catalina OS on it). So there’s nothing to choose, and nowhere to go, haha.
Well, I had a “High Sierra” installer usb - that I was smart enough to save. High Sierra being the most recent “natively supported” OS for my model if I remember correctly (that’s why I kept it).
I closed the “choose startup disk”, inserted a my High Sierra installer usb into a usb hub and connected it, then used the apple icon to restart in top left to choose “restart”. Then I used the installer, and just successfully installed High Sierra.
Wondering how I should retry this OCLP process again to install either Sequoia or Sonoma. I remember one guide I was watching said to "update to highest OS supported by your machine (high sierra for me…?) first. But I was on Catalina (unsupported), so I decided to try it without being on high sierra first.
I downloaded discord because I read somewhere there’s a server there for OCLP help, but I don’t know how to use discord, hah. So a simple 1-2 hour thing becomes several days of reading, vid watching, joining forums, waiting for answers, etc. etc.
EDIT 1: High Sierra 10.13.6 running on MBP. Downloaded OCLP again, and currently downloading macOS Sonoma 14.7.6 (not Sequoia). I will try and make a Sonoma installer when this is finished. Then I’ll try installing it.
