Hey guys I need help please. I went to so much trouble just fixing my MacBook. I restored my mid 2012 MacBook pro that has already Catalina, but then I encountered plenty of errors while trying to reinstall. So I ended up reinstalling to it's original OS X Mountain Lion. Now, I'm not sure what's next after this.. I am really hoping that I can still reinstall Catalina. Is it possible?
Hi there, if you got a time, can I please ask you again? Start from the beginning, these are all the things I did.
I restored my MacBook to factory settings then reinstall El Capitan, now I'm waiting for the macOS Catalina to finish installing. Oh by the way all the macOS updates were installed on my external drive as there wasn't an option earlier for me to do that in my main internal drive (can't see it). Now as I'm finishing installing mac OS Catalina, internal drive is not visible when I looked up in start up disk. When I checked disk utility and click on first aid, it doesn't mention problems just scanned and all done. The "Mount" option is not clickable. I looked up on web and it's kind of confusing. Is there a simple way to do this? Thanks for your time.
You're welcome. First, you need to click on the El Capitan link in the article. Once that is installed, You can search for Catalina in the App Store. This will take awhile.
You will need to install El Capitan first.
I see, do I see that in software update or is that the one I need to get from app store? I really appreciate your help. Thank you so much
Once again, thank you so much. I hope you don't mind if ever later I have a follow up question. Have a great day!
No Problem. You're welcome.
Never mind about this. It fixed itself. Now my only question is... since I installed macOS using my external drive, will my MacBook still works once I disconnected my external drive from it?
