Part 2. How to Clear System Storage on Mac
To ensure the system runs successfully on the computer, the macOS system and its system files CANNOT be deleted, but the rest on the list can be erased to free up the system storage. Most of the system storage files are hard to locate and the amount of this kind file are enormous. We might even delete some important files by mistake. So here recommending the program FonePaw MacMaster to clear up the files mentioned above, and it won’t accidentally delete the important files.
1. Delete System Cache and Log Files
System logs record the activity of system applications and services which take up lots of space on your Mac. They are useful to the developer for the purpose of debugging but are usually useless for regular users.
To delete files first is to access/locate system log files on macOS. It usually involves the steps of typing the code on Mac, then manually removing those files into trash. It might become too complicated for users who are not familiar with macOS system. But now you can use FonePaw MacMaster to clear them up with just one click. The steps by using MacMaster to clean log files as well as the system cache are as followed:
- Download MacMaster on your MacBook or iMac, the program is totally easy to use and free to download;
- Open the program, choose System Junk and click Scan;
- Choose System Logs and System Cache in which the files have been presented in the right column;
- Click Clean to selectively delete some of the log files and cache or you might delete them all in once.
2. Delete Mail Attachments
Every email and its attachment will be cached on your mac when you received them for reviewing offline. The accumulation of the mail attachments will put great pressure on the system storage. To reduce system storage on Mac, you need to get rid of the attachements that you need no more. If there are too many attachments needed to be deleted as well as the cache generated by Mail, MacMaster is very helpful to speed up the process.
- After scanning in the program, select the Mail Junk or Mail Attachment that will be presented in the right column;
- You can selectively delete some of attachments or delete them once for all by clicking on the Clean button.
Remind you that the mail attachments deleted by FonePaw MacMaster will not be removed permanently. You are still able to re-download the files from the mail server if you want to.
3. Delete Useless Files from iTunes
Some of you might use MacBook or iMac to backup iPhone’s or iPad’s data by iTunes. The updates of the iOS system can also be completed through iTunes, and the updated files as well as iTunes backup could make system storage huge. The iPhone backups and iOS updates files can deplete the storage up to 10+GB on Mac without knowing it. So removing iTunes files is a great to clean up system storage on Mac.
The backup files can be removed through iTunes, while the update files are a little bit tricky to locate. But with the help of MacMaster, it will become much easier to remove.
- In FonePaw MacMaster, choose scanning ‘iTunes Junk’ to scan out the unwanted backups and updates.
- The filtered files will be presented in the right column. Click Clean to remove them easily.
4. Empty Trash
Dragging the files you don’t need into the Trash doesn’t mean the complete deletion from you Mac, but emptying the Trash does. We usually forget the files in Trash, and it’s very easy to pile up, thus becoming a large part of system storage. So if you clear System storage, follow the steps below to empty your Trash:
- Click and hold the Trash icon on the Dock (or pressing the right bottom with your mouse).
- A pop-up will appear that says Empty Trash. Choose it.
- Or you can also empty the Trash by opening ‘Finder’ by holding down the Command and Shift, then selecting Delete.
5. Manage Time Machine Backup
Time Machine works through using both remote storage devices and the local disk for backups if you are making a backup via Wi-Fi. And the local backups will increase your computer’s system storage anyway. Although macOS will automatically purge the local Time Machine backup if there is ‘not enough storage disk’ on Mac, the deletion sometimes lags behind the storage change.
Therefore, it’s critical to manage Time Machine backup. Here we will recommend a workaroung to help you delete the Time Machine backup files on Mac manually. But note that, though this method can help you remove the backup files on Mac and release more system storage space, if you are afraid of deleting some important backups on your own, you can also choose to wait for the macOS to delete them.
- Launch Terminal from the Spotlight.In terminal, type in tmutil listlocalsnapshotdates. And then hit the Enter key.
- Here you can check the list of all the Time Machine backup files stored on the local disk. You are free to delete anyone of them according to the date.
- Back to the terminal and type in tmutil deletelocalsnapshots.The backup files will be presents by the snapshot dates. Delete them by hitting the Enter key.
- Repeat the same steps till the system storage space is acceptable to you. (Tip: During the process, you can check the System Information to see whether the disk space is large enough.)
