iMac late 2015 running Mac os 10.15.4: Connection Logging file is to big to delete iMac late 2015 running Mac os 10.15.4: Connection Logging file is to big to delete - not enough storage available. It is 53GB. Available storage is 43GB. I have moved as much user data as possible to external drives. How do I get round this?
If all you want is to delete the file you can open a terminal window by launching Applications -> Utilities -> terminal , typing rm into the terminal followed by a single space, then drag the file into the terminal window (it should copy the name &amp; full path into terminal) and finally hitting enter.

That location looks like it could possibly require admin privileges to modify files. This would be for a good reason: don't modify any files unless you're completely certain that it's safe to do so. If you do run into access issues, it's possible to proceed by typing sudo followed by a space, followed by the line you would have generated in the previous paragraph. Proceed with caution and make sure you have an up to date backup before trying this method.
