If you use your Mac to back up your iPhone or iPad, you can delete old backups.
Also choose Mailbox > Erase Deleted Items. If you use the Mail app for your email, choose Mailbox > Erase Junk Mail from the menu bar in Mail.Delete files in your Downloads folder. Open this folder from the Dock, or by choosing Go > Downloads from the menu bar in the Finder.Delete music, films, podcasts or other media, especially if it's media that you can stream or download again as needed.You can also delete files you no longer need. Wait a few minutes for the local snapshots to delete.If you have another storage device, such as an external drive connected to your Mac, you can move files to that device. Media files such as photos and videos can use a lot of storage space, so you can take steps such as these:.Open Time Machine Preferences from the Time Machine menu in the menu bar on your Mac.To disable local snapshots in Time Machine and remove them from your internal storage: It will also stop Time Machine from creating new snapshots. You can use a Terminal command to disable Time Machine's local snapshot feature, which will delete all of the local snapshots on your internal hard drive. However, if you really need to delete those snapshots (which I don't recommend unless you desperately need that space), there is a way to purge local snapshots from your internal hard drive.

That being said, everything doesn't always work correctly, and you may find yourself out of storage space on your internal hard drive, and those snapshot backups won't go away. The program will then continue to replace the old snapshot with a new one until you free up space on your Mac's internal storage, at which point it will go back to saving weekly snapshots as long as space permits. If you then, say, download some large program and your internal hard drive plummets to below 10% (or less than 5GB of internal storage), Time Machine will delete all local snapshots except the most recent. If everything is working correctly, Time Machine will automatically delete the oldest snapshot backups as soon as your internal hard drive has less than 20% of storage space left. First, let me preface this by saying that you shouldn't worry about those backups and the space they are taking up.
