You need iOS software update files in order to update the software of your iPhone, iPad or iPod via iTunes. But those files are quite large and you don’t really need them after the update is done installing. Let’s free up some space by deleting them.
Manually removing old iOS firmware files from your Mac
You can find update files at ~/Library/iTunes, in which “~” is your Home folder. Keep in mind that software updates may diffe: iPad firmware files will be kept at ~/Library/iTunes/iPad Software Updates. You can find the same files for iPhone in ~/Library/iTunes/iPhone Software Updates.
Automatically removing old iOS firmware files from your Mac
Remember the CleanMyMac 3 app we wrote about this week? Well, good news is it can also remove old firmware files for you.
To do that, launch CleanMyMac 3, hit “Scan” and then “Clean”. The app will clear out all the junk in your computer, including old update files.
You can also delete only the update files by opening the iTunes Junk feature of CleanMyMac 3, hitting “Scan”, clicking “Review Details” and then selecting the iOS software updates for cleaning.
