If you don’t feel like spending a bunch of time to find and clean things up manually, you can use CleanMyMac 3 to get rid of temporary files, clean up extra language files, uninstall applications, get rid of extra files left behind by application uninstallations, find and get rid of big attachments stored in Mail, and a whole lot more. If you fail to keep your Mac’s hard drive clean, you’re eventually going to get the dreaded “Your disk is almost full” error, so you may as well start now and clear up some space. Most of the wasted space on your Mac is only going to be reclaimed if you look at lot deeper-cleaning out language files, removing duplicate files, deleting attachments, clearing temporary files, or emptying all of the Trash cans. You can obviously free up disk space by simply doing a cursory find-and-delete for big files and other things that you’ve downloaded, but realistically that’s only going to get you so far. Here’s how to clean up your Mac and reclaim some drive space. Luckily there are quick and easy ways to free up space on your hard drive. Even these days, MacBooks still have tiny hard drives that fill up quickly.
