Why Is My Mac System Storage So Big?

Mac users often freak out when they look at the Storage settings in About This Mac and find that System storage takes up way more space than they think it should. However, if they wait a bit the storage meter will continue to calculate what takes up space and allocate it to iCloud Drive and other things. Even once this is done, a fairly large System storage amount can be accounted for by looking at your System folder, system Library folder, and user Library folders.

    Good topic but no mention of indexing which is also relevant. Apple recommend indexing to clarify

    Peter: Not sure how indexing applies to this. Can you clarify?

    Large files could be caused by indexing issues. Snapshot first aid then re indexing the drive. My system file was 537 Gigs system crawling. Many coloured balls. Combination of your advice and apples sorted problem system now 33.4 Gigs cheers Garry
