I have a 250GB SSD hard drive on my Mac.
Last time I checked the remaining space was about a week ago when I removed Bootcamp and free'd up an extra 50GB of space. This left me with around 150GB space remaining.
I've just checked today and only have 60GB free!
I've also instealled 'Clean my Mac' and checked for junk files, but it only found 9GB worth.
The only real folders I can think of that take up room are my Dropbox folder (which contains all of my files, at least all those that I'm aware of) and my Applications folder.
Both of those folders combined only take up 50GB amount of space according to Finder.
I read that the 'Library/Caches' folder can take up a lot of space there, but only found 10GB (possibly what was found my CleanMyMac)
I've also emptied my trash.
Also I read on another forum about running the following command in Terminal:
~ % sudo rm -r /System/Library/Caches
But I just get the following error:
rm: /System/Library/Caches: Read-only file system
I can't even think of where else to look for what could be taking up all this room?
