One of the best ways is to clear cache files, old iOS backups, log files, and unused downloads, as these often take up a lot of System Data space. I’ve also found that removing large attachments from Messages and restarting the Mac after cleaning can help. If the storage still looks unusually high, checking for Time Machine local snapshots is worth it since they can consume a surprising amount of space.

1 month agoThe best ways to reduce System Data on a Mac are to clear system caches, remove old iPhone or iPad backups, delete temporary files and logs, uninstall unused apps, empty the Trash, and restart your Mac regularly. You can also use Storage Management to identify and remove large, unnecessary files safely.

1 month agoOne thing that helped me reduce System Data on my Mac was clearing old caches and deleting unnecessary backups. I also checked the Downloads folder, removed unused apps, emptied the Trash, and restarted the Mac to let it recalculate storage. If it's still taking up too much space, a storage analyzer can help identify what's actually using the space.
