To check what’s taking up space on your mac, you can choose “Manage” on the startup disk warning notification. This means keeping your disk clean is extremely important for daily operations. You’ll get a message from Apple when your disk is almost full, and if it fills all the way up you won’t be able to download new files, open attachments, or install new programs.Īn overfilled startup disk will also cause your MacBook to run slower since it won’t be able to use RAM as effectively. Most MacBook users will have just one disk named “Macintosh HD” by default, power users may have two or more. However, as time goes on the files and apps you add to the MacBook drive will begin to accumulate and limit the space remaining on that disk. Please, also read how to safely and efficiently locate the real space wasters.You can’t get rid of that disk because it’s what your Mac uses to function. If you find an unknown large file that doesn’t appear normal, search online or ask us whether it’s safe to delete.Īnd of course, make sure your Time Machine is always up and running! In this case even if you delete something accidentally, you will always be able to roll back. If you need to trim the content of one of Apple’s application libraries such as iTunes or Photos, or remove some Time Machine backups, use their own corresponding UIs. Typically, it is your own files that take up the most disk space, not the system files, so there is no real need to touch the latter.

So the recommended rule is the following: only delete the files that you can recognize (by location, file name and preview of content) as those you have created or downloaded yourself, such as videos, games, music, downloaded programs etc. That said, it is still not impossible to break normal operation of some apps by mindlessly deleting files that you are not sure, or have no idea about. Fortunately, this cannot happen with DaisyDisk, because the app is smart enough to not let you even put such files to the Collector:Īnd we keep on working hard to make DaisyDisk even more safe to delete stuff with. It’s a common worry to not accidentally delete some critical files, which could break your system’s operation. How do you know what should be deleted, and what should better not be messed with? So, you have scanned your disk and got its sunburst map.
