Problems upgrading a 2013 macbook pro retina to Big Sur (or Catalina)?
Is anyone else having an issue upgrading a late 2013 Macbook Pro Retina to Big Sur or Catalina from Mojave? Apple's site suggest indicates my model should upgrade to either but I have not had success with either, yet.
Big Sur is the only update that shows in the Software Update screen from the apple menu...I tried a combo catalina update file 10.15.7 for Catalina since it seems to be missing from the App stor. Both stops due to an error during installation after an hour or so of processing. I have tried both internet restore and downloading the installer application file and running it from an external startup disk.
Trying to upgrade because TurboTax 2021 this year. Any suggestions would be appreciated.
Thanks, Dan
