I recently upgraded to Catalina but realised a few apps don’t work as they are 32-bit.
I have heard of dual boot system and did some googling. However I couldn’t find any help with what I wanted to do which is – have Catalina as my main OS but create a bootable Mojave on the same MacBook. So that I can switch between OS if I want to use 32-bit apps.
Can this be done?
