I am using a mac mini.
After having issues after upgrading to Mojave, I found info on TechRadar and checked for 32 bit software on my mac.
I was surprised to find that I have iMovie 9 as well as 10.10, and old and new versions of Word, Excel, Powerpoint for mac as well.
Can I delete these old 32 bit versions, or are they somehow underlying the new versions? I can see they are in a folder called Office 2011.
My microsoft apps are part of an Office 365 subscription.
