What OS system can my MacBookPro handle
I have a MacBook Pro from 2012 running Mojave 10.14.6. What OS system upgrade can I safely run?
MacBook
If you are considering upgrading to Catalina be warned that it does not support 32bit apps.
Your Mac is probably running 32bit apps and these will need to be updated to 64bit apps,
some updates may be free, some may be paid. Use this app to discover which apps you have
are 32bit, https://www.stclairsoft.com/Go64/. Once the list has been created you can then
contact the developers of the apps to see if they provide 64bit updates.
Before upgrading make a full back up of your mac, in case you want to go back to Mojave.
