"hidden" backup files on the internal drive, but it says they are on the external drive. in /Volumes/.timemachine/B0E8FC8F-C206-4778-88DA-B1119BD2E320/ apparently dated for backups but if I do a du -sh on them it's the external backup that has "activity" not the internal drive. It reminds me of a song... "Where has all my disk space gone long time passing, it's gone to apple every one..." I'm also trying du from cron & getting this... du: /Volumes/JohnD/johnd/Library/Containers/com.apple.mediaanalysisd/Data: Operation not permitted  44K /Volumes/JohnD/johnd/Library/Containers/com.apple.mediaanalysisd du: /Volumes/JohnD/johnd/Library/Application Support/MobileSync/Backup/: Operation not permitted Needless to say /Volumes/JohnD/johnd/Library/Containers/com.apple.mediaanalysisd/Data is full of crap I really don't want happening on this machine!!!
