The model and year of your Mac will determine which macOS you can upgrade to, as you have a 2017

iMac you can upgrade directly to the latest OS Catalina, but Mojave and High Sierra are still available,

read the following links.


How to upgrade to macOS Mojave - Apple Support

How to upgrade to macOS High Sierra - Apple Support


Before upgrading make a full back up of your Mac.


Check that third party apps you use have updates available for the new OS.

Check that your printers/ scanners etc have updated drivers and software available for the new OS.


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.
