I expected this to reset the MacBook Air and get storage back to at least 80% of its prime. I removed all the files after backup (DID NOT USE TIMEMACHINE for backup), and factory reset my computer. Went through every file I had and organised and cleansed it. I went through my computer this weekend and deleted files I do not need anymore and made backup of files of the ones I do. This weekend I decided lets try fix this problem I ended up only have a fraction of the applications I used to be able to have, as there was something that kept taking up more and more space. Very quickly something would use up this space and I would have to go through the process again trying to free up more. I kept deleting apps, restarting MacBook and constantly running cleanmymac to free up space. It would then only take a few days and then that storage would be used up by something else. I then bought cleanmymac (I think that's what it called) to clean my computer and deleted an app I hardly used. Suddenly the storage was completely filled, after just using it and not downloading anything. A month ago it started getting really weird though. I started getting the problem of limited space, and had to change what applications where on my computer as needed. I needed a ton of applications for school and work and I am very limited with the 128GB.

This problem started occurring a few months ago. I was starting to get problems with my MacBook Air regarding available space.
