iMac 2011 software update
Hello - I’m trying to update my mid 2011 iMac to version 11 or higher so I’m able to run an app on it. Is this possible? It’s showing that my iMac is all up to date but is currently running on MacOS High Sierra version 10.13.6.
Would really appreciate any info or suggestions on how to get my iMac to version 11 or higher.
Thank you, Joel.
