How do I clean up after Apple migration Assistant on my new iMac?
I just set up a new 2021 M1 iMac, replacing a 2015 21-inch iMac. The Migration Assistant appeared to hang during the setup, so I cancelled it and re-ran it standalone after setup had completed. I now have 168GB of my storage listed as 'Other' taking up far more drive space than on my old iMac. Is there a way to identify duplicate or other unnecessary files created during the data migration that I can safely delete or will I need to erase the drive, reinstall MacOS and restore from a Time Machine backup?
