Why Should We Clean System Storage

Most wasteful space on your Mac will be recovered by addressing deeper elements such as duplicate files, language files, attachments, temporary or empty files of your Mac repository.

It is better to know the system storage on Mac before we get to the solution. On Mac and in storage, we can see that Mac storage is divided into several groups, such as photos, apps, iOS files, audio, system, etc. And the storage in the system is confusing and it's difficult to know what is in the system. In general, system files cannot be categorized in the system storage.

Updates of the iOS system may even be done by iTunes, which can make system storage very important for updated files and for iTunes backup. The iPhone backups and iOS updates can deplete stock on Mac to gigabytes without any knowledge. Deleting iTunes is a great way to clean up Mac system storage.

Time Machine Backup Deletion

Time Machine operates both with remote and local backup storage devices when backups are done via Wi-Fi. And the local backups will still increase the system storage of your computer.

But be aware, although this method can help to delete Mac backup files and to free up more system storage space, you can also wait for the MacOS to delete them in case you are afraid of deleting some important backups alone.
