Prior versions did a permissions check and told you if there was anything found and whether it was fixed. "First Aid" has never "found a thing" even when the problem stopped after it! Why no feedback and how do I ever know what was wrong with it?!

Apple introduced SIP a long time ago, System Integrity Protection, which effectively meant that permissions could no longer be changed on System files, therefore it was no longer necessary to include it with Disk Utility.

Disk Utility since then has NEVER turned up ANYTHING wrong with my system or disk when I strongly suspected it due to really slow processing time or frequent freezes. Didn't it used to tell you when something was found wrong and that it was corrected or that I would have to do something else to correct that problem? I just get the feeling I'm being placated with a do-nothing system check.
Disk Utility> First Aid only checks the directories on your Mac not the entire disk.
If you are experiencing regular system freezes and slow processing this could be
a physical problem with the disk rather than the OS on it. Is your MBP quite old
does it have a spinning disk?
It will still tell you about problems, but in some instances if using APFS it'll be unable to repair them & Reformat is the only cure for that so far.
