MacPaw CleanMyMac and reImage

This App should point out their hidden files...

EtreCheck is a simple little app to display the important details of your system configuration and allow you to copy that information to the Clipboard. It is meant to be used with Apple Support Communities to help people help you with your Mac.

Pastebin is a good place to paste the whole report if you capture the URL while there…

Workable but harder for me to work with...the Note tool on the bottom of this editor's toolbar, as shown in the image, to copy and paste the output from EtreCheck.

you need to go to their website and look for uninstall instructions.

Here are the instructions from macpaw:

As for what you said was "relmage" - is it reimage? That would probably be adware/malware. I'd download and run Malwarebyytes for Mac (free version). That should get rid of it.
