Considering the transition from HDDs to SSDs and the dollar's upward trend in recent years, I risk that a lot of Mac users have lost storage space in their most recent computer exchanges – this one that writes to you, which came out of a MacBook Pro 500GB for a 128GB MacBook Air, can be considered an example.
For these and other reasons, saving megabytes of storage is increasingly important – and sometimes your Mac simply has a portion of the space occupied by files that you don't even know how they got there. Want an example? Just talk about the infamous “iOS files”.
If you've already plugged an iPhone, iPad or iPod touch into your Mac and made a local backup of the device on it, you will certainly have a few gigabytes occupied on your computer by this type of file. To check it out, just click on the Apple in the upper left corner of your screen, then on About This Mac »Storage» Manage and check for the presence of the “iOS Files” element. In some cases, it can occupy several precious gigabytes of space.
To make it clear, the “iOS files” that take up space on your Mac are old backups of your devices saved in your computer's memory. If you are in the habit of still making local backups of your iPhone / iPad / iPod touch, their presence is inevitable and you should not delete them (or you should not delete the latest ones, at least).
Most users, however, have already chosen to do their backups on iCloud – a more flexible process that naturally takes up no space on your Mac (we have a full video talking about iOS backup options, for those who want to) . If you have already migrated your backups to iCloud, there is no need to keep “iOS Files” on your Mac.
Fortunately, it is very easy to delete these files. When you reach the screen in the image above, just click on “iOS files”, select all the backups you want to purge (see the “Last accessed” column, if necessary) and click on “Delete”, confirming the operation in then.
Ready! Magically, you have freed up some precious gigabytes of your Mac's internal space. 😉
