If you're not using Catalina already, then do some research on all the problems associated with that. YMMV: this also depends on your reliance on third party software vs Apple walled garden app store; in my experience also depends on drives /data that may be migrated (permissions and security can be problematic - 1st, turn off all the T2 rubbish, then you may need to set drive permissions etc); finally also be aware that 10.15.4 is bricking some machines and this requires another mac to fix the firmware etc - having said this, this particular issue does not yet seem to effect the MP 7,1. In sum: Catalina is a real dog, so be careful and circumspect in your setup. Like odd Apple practice in the recent past: machine cannot go backwards in OS & so we are forced to use that; OS also drops much 3rd party app support (again, YMMV depending) but mostly, if so, then we are forced to buy updates for many apps.
