I've been using the MONIT app to check my usage of RAM and storage and etc. Nowadays it seems really awkward for me. My Mac says I have 100 GB free space but MONIT says only 40 GB is free. I checked their FAQ and it says there should be cached files which apple's not showing on the storage. I tried everything and couldn't find the difference between them. What could be the 60 GB file difference ? How can I find them ?
