HI, I have a 13in macbook pro 2011 (i7) 500gb, 8gb ram.. Ive had it for about a year, i purchased it while deployed in afghanistan. Up until recently i have always only used about 250 gb of my hard drive, while using external hard drives for movie and music files. In the past two weeks I have started to get a message saying my startup disk is full; when i opened up my disk utility it shows roughly 269gb being used up for audio, movies, photos, and apps, while over 228gb of memory is filled labeled under the category of other. I can not account for any of the memory thats labeled under other, while holding down the "option" key and selecting go in my finder i have searched every file that's in my hard drive and still i can only account for 270gb or so being used. I had forgotten that i had mackeeper installed which i have been told is a type of malware so i have uninstalled it but it did not help. Anytime i delete any files to try to free up space it is instantaneously filled up and categorized under the other category. Yesterday the other category was at 201gb and then trying to free up space i deleted 27gb of movies on my hard drive now the memory has been taken up by "other". Somebody please help. Ive tried calling applecare and had no luck. I dont have enough space on an external hard drive and do not want to fork out another 100 dollars so that i can make a time machine backup and reformat my macbook. Thank you for your help. -tim cordial
