Answer 1

Recommend CleanMyMac for updating, cleaning and repairing your Mac. It offers trash empty for your trash can or largest files, free up RAM space, uninstalling software controls and system's clean up. It costs about $34.95 for 1 license, but considering if you use it consistently that it is beyond worth the price.

And it does other things also that you can test during the trial period.
