First... Safe Boot from the HD, (holding Shift key down at startup).


Safe mode attempts to repair Disks & clears lots of caches, so if Safe Mode works try again in regular boot.


Don't use Firefox for this link...

If you get a corrupted message...


Naw, not damaged, it's just that you have an old copy already in Applications, there are 2 cures...


Disconnect from the Internet & set the Date back to 2014, then you can run the Install MacsOS High Sierra App in Applications, so expired Certificates are not expired.


Or... trash the Install MacsOS High Sierra.app in Applications then a new copy more recent version can be downloaded.
