Upgrade feasibility?
I have a 2017 iMac with 16 GB memory, now on OS High Sierra 10.13.6. Would like to upgrade, but am concerned about the large jump in upgrades. Can I upgrade in 2 or more steps to make it less of a change? Is it safe to just go ahead and upgrade? I've never had problems in the past, but have never let things go so far without an upgrade?
