My mac has ghost storage space

Ah yes, the "system" taking up all your freaking gigs. I've had this issue before, and another way to see exactly what's taking up all the space is when you click on the Apple, then About This Mac, and then Storage, you'll see it change if you just wait for a few minutes. It takes some time to assess what is eating your computer alive. Once you can figure out what that is all about, just look for those files themselves in your hard disk. In your main screen, try holding the option key down, and click on go, which then pulls up the Library option. That should provide you more options to find out where those pesky files are. Apple really needs to change this. Let me know if you're still having a problem!

Nope, you're good! I understand. It could be a number of issues. I'm not in your computer so I can't see how you've utilized that space. It could be other users on your computer, it could be virtual machines that you've made. It could be cookies, and "system" are often times files that you can delete manually. Try going to your library from the option key trick I mentioned, and then look for application support folder. Mine takes up 3 gb, and it's showing apps that I thought I already deleted, sooo going to that now xD If you just right click on a folder it will tell you how much space it's taking up by clicking on "get info" and from that you can begin to determine what folders are fatties, and which are skinny on the kilo diet. Let me know if doing that doesn't help. You definitely don't need to buy extra storage, you need to push Apple for answers, because it's a very very common issue. Also, try this. Go to your main screen, click on "go" then click "computer" click on "Macintosh hd" and THAT should show you all the stuff you've got.

Don't delete one's that you don't know about, that could cause you to have to take it into the store to have them factory reset. Don't fear taking control of your computer, just look in those folders for potential videos that you've made and no longer use, or snippets or whatever, and just delete them manually. It should be simple enough to navigate once you start from the folder I told you about, because they branch out like a tree.

(PS I tried messaging you right away, but because Apple is a little club apparently that I'm not in, even though I have their products, I can't message you right away when I see a response LOL. What a petty club to be in, I'm only lvl 1, so I am not special enough to help you yet. Terribly sorry)

EDIT: you can try to narrow it down by clicking on the first few folders it shows from the HD Macintosh part, and seeing which take up the most space. Click on that one, then see all the new folders it shows. Do the same "get info" on them and then follow that folder. When you keep digging, you'll start to see folders that you potentially recognize and can delete. Hope that helps!

hahahahaha you're welcome!!! I'm so happy to help, your reaction was priceless and now I have a dumb smile on my face. xD Just keep investigating, storage is a strange business :P Have a great day!!!!!

Hi: Use Disk Utility check on your total free storage, etc. Here is what I show.
