OS preference

Upgrading from Sierra due to 3rd party software requirements. Need to have High Sierra or Mojave or Catalina. What say you ?

nwyaker,

If you're totally done with 32-bit applications and/or everything you use is compatible with Catalina, considering going with it. If you're in my situation and still require apps that are 32-bit and/or are incompatible with Catalina (and newer), go for Mojave. This assumes everything you're using is compatible with Mojave. The usual precautions apply.

Backup prior to moving to the new OS.I always perform a full clone backup prior to upgrading the OS. That way, if something goes wrong, it's super easy to restore the machine to its pre-upgrade configuration. I moved to Mojave quite a while go. I have a clone backup of my current configuration and still have clone backups of High Sierra, Sierra and El Capitan. 'course, the older clones are on platter drives which I stopped using some time ago. Still have them, though.

What Mac? SSD? How much RAM?

Do you use lots of older software? MS Office? Adobe CS apps? Quicken/Quickbooks?

How do you feel about change?

New Mac in the near future?

High Sierra at least.

Thanks Robert. Install will be on USB3 external, so not mucking up other OS.
This drive dedicated to one application.

I prefer Ubuntu anymore.

Must be a pretty special app.

The latest I am using is High Sierra. Still using mainly Sierra on my Mac Pro.

Catalina has been great for me, no issues. I should point out I don’t use mail and all my apps are approved for it.

cMP & MBP (nr), all on Mojave. cMPs also have Sierra & HS on seperate
SSDs.

I say it depends entirely on the computer model, the hardware installed and the software want to use.
