Sorry about that. (iPhone auto correct did me wrong, and not re-reading)
Let's start from the beginning.
I have an old [MacBook Pro Version (Not Sure] It won't let me see "About this Mac" Option and when I turn on has a file with a question mark. Only when I press command+r before turning on will it take me to utilities. The update it says I can update but doesn't is Lion OS X. At first I didn't want to delete everything inside the MacBook Pro but being that I can't afford to fix it and have a MacBook Air now, I figured I'd do a factory reset. An apple rep followed me through some steps to try an updated and erase everything in the MacBook Pro through Disk Utilities by deleting the current disk and then being able to download the update. (An apple rep told me to delete the current disk on it, to be able to update to OS Lion.) However, that was a fail.
It didn't work. So, then we tried to use my MacBook Air with macOS Catalina Version 10.15.4 (works perfectly fine) to create a bootable disk with a 16g Usb drive that we were able to format to accept the update (That worked fine). Then, we tried to download El Captitan on my MacAir but it wouldn't download (Said it wasn't compatible to download with my Mac) Even though we prepared the USB and did all the steps (Also it says my computer is compatible to download El Capitan on on the forums, so I am not sure what went wrong.
Now when I turn on the MacBook Pro it has the file with the question mark, unless I use command+r or command+shift+r which takes me to internet recovery with the moving globe, makes me input my internet connection credentials and then takes me to disk utilities. Not sure what to do from here. Thanks for the help in advance. Sorry for the mix-up.
I know this is not apple support, I spent 5 hours on apple support yesterday and 3 different reps. I thought maybe someone in the community had a similar problem. The first two apple support techs helped me greatly and were positive it would work, the last just didn't really help and kept pushing me to go to a store. (Even though everything is closed due to covid-19)
