How do I clean up minor issues on my iMac using EtreCheck?

Since we have no idea what you are seeing in the EtreCheck report, we can't really offer you any advice on what your next steps are.

If you want assistance, please post a copy of the report using the "Additional Text" tool in the forum's editor.

Another vote to post the report. What seems insignificant to a new Etrecheck user can speak volumes to those of us who have reviewed thousands of those reports over the years.

What Minor Issues are showing up in your EtreCheck Pro report...?

The ones that show up on our 2018 Mac mini are just what it states, Minor Issues:

I use multiple CarbonCopyCloner clones instead of Time Machine.

Occasionally I have a lots of App's open that exercise the RAM and CPU.

Yeah' it's a 2018 Mac mini model that can only run up to macOS 15 Sequoia.

We use File and Screen Sharing between the Mac's on our local Ethernet network.

So basically, nothing out of the ordinary there to get worry about.

If you are having other problems with your Mac, then please post your EtreCheck Pro report.

That would depend on what etrecheck detected...
