If you open iTunes and choose iTunes> Preferences from the menu bar at the top of the screen, you can then click on the “Devices” tab to see a list of iOS backups you’ve saved on your Mac.

These backups are important but can take up a lot of space depending on the capacity of your iDevice and the amount of data stored on it at the time the backup was made.

While I don’t basically recommend deleting your current iPhone or iPad backup, check this list to see if you have any old or unnecessary backups, for example, those from old iPhones you traded in or those made before an iOS upgrade.

If any of the upgrades in this list are no longer needed, just click to select one of them and press the Delete Backup button.

The Downloads folder is the default location for all of the files you download in Safari, Chrome, or Firefox, but thanks to the way that these browsers can automatically open or launch files once they’re downloaded, many users build up a huge quantity of old and unnecessary refuse in this folder. To check out your own Downloads folder, launch Finder and find Downloads scheduled in the sidebar.

Once that folder opens, spend a bit of time looking through it and trashing what you don’t want. Almost all disk images, for example, can be deleted.

Another helpful tip is to change to List View and sort your files by date, or size. This can help you identify which files are the oldest or largest, helpings you quickly find good candidates for deletion.

You can also empty the trash on your Mac by right-clicking on the Trash icon in your Dock and choosing Empty Trash, or by launching Finder and using the keyboard shortcut Shift-Command-Delete.

Delete Unnecessary Media From iTunes

Since its first appearance in 2001, iTunes has grown from a humble MP3 manager to massive application which handles music, movies, TV shows, podcasts, audiobooks, and iOS apps. As a result, the media stored in iTunes is often the single largest consumer of your Mac’s precious storage space.

Just Reboot!

If none of the above suggestions gives you enough free space to get by on, then it might be time to consider some more serious options.

In the absence of an internal storage upgrade, however, external options are always available, and you could think about moving your entire iTunes or Photos Library off onto an external drive.

I don’t usually recommend doing so, however, since this approach will make backups and management more cumbersome. If you absolutely have no other choice, though, you’ve gotta make room somehow.

And finally, if the “About This Mac” window doesn’t give you enough information, you can always consider using a third-party utility to see where all of your space is being taken up.

There are tons to choose from, but my favorite is OmniDiskSweeper from The Omni Group. If a first pass with OmniDiskSweeper doesn’t catch everything, try running it with superuser privileges.

The solution to “I have to free up space on mac startup disk” is definitely not “let’s go delete stuff in the System folder”.
