Best MacOS for Mac Mini

[kona0197]

So I recently picked up a low milage 2018 Mac Mini. Currently has MacOS Sequoia 15.5 installed on it. The system is quite laggy, probably due to the 8GB of RAM. I am curious what version of MacOS would work better on the system. I know I can grab Ventura or Sonoma from the app store. Not sure where to get official earlier systems.

And how do you turn off the notifications to upgrade to the latest MacOS after installing an older version?

Leave it on Sequoia and put more RAM into it. My 2018 MacBook Pro is fine running Sequoia with 16Gb RAM.

RAM upgrade would be nice, just not feasible at this time.

I sympathize with you on the upgrade not at this time, how ever the reason your system is "laggy" is due to the 8GB. Downgrading to an earlier ver., probably won't make your system any speedier. I'm not sure how involved the upgrade would be, but that maybe the only the option for less beachballs. Maybe check out iFixit just to see how involved an upgrade actually is.

You could try Mojave. I have it running on a 2014 mini with 8 gb ram and do not experience it as laggy.
