I have an old Macbook Air. Why does HD only allow access to 30 GB when the drive is 121 GB? (See screenshot inside.)
As the title mentions, I have an older (Early 2014 MacBook Air OS X Yosemite). I'm not very knowledgeable on Macs but I know some basics.
The 'About this Mac' window shows the hard drive should be 121 GB, but looking at the storage, it appears I only have 30 GB available to me (I can't even explore the other 90 GB to see what is using the space). I am aware that a chunk will be system files, but 90 GB seems like a lot, and it seems like I should at least be able to access/look at those files or to see what is taking up so much space.
I have attached a screenshot showing some information that will hopefully be useful.
Any help that can be provided in figuring out how to access the mystery 90 GB would be greatly appreciated.
