I (foolishly) attempted to upgrade directly from Success' href='/2020/12/install-macos-mojave-on-supported-pc.html'>Mojave to Success' href='/2020/12/install-macos-catalina-on-supported-pc.html'>Catalina using the App Store. When the download finished, system attempted to reboot. System shows error messages and is not booting anymore.I was running the current version of Success' href='/2020/12/install-macos-mojave-on-supported-pc.html'>Mojave and upgraded to the current version of Success' href='/2020/12/install-macos-catalina-on-supported-pc.html'>Catalina as of May 15, 2020.
Someone suggested that I change a bios settings, did so but still having the issue.
Suggestion:
(Serial ports (SuperIO) should be disabled in the BIOS settings.)
I am currently seeing the following error message when trying to load the system.
thank you for your help.
