My macbook pro has been acting up recently. It told me that I have no more space left on my start-up disk. Upon investigation I saw that I had filled my hard drive with 100 Gb of "other" data. (I only have around 20Gb of music, movies, photos, and apps.) This was yesterday. I then decided to fix the problem by removing the partition on my hard drive that bootcamp was using because I rarely used windows in the fist place. I figured that the new space would be sufficient, but today when I logged onto my computer it informed me that is was still low on start up space. It had gathered 40 more Gb of "other" data!! So now, I only have around 300Mb of space. What is going on!?!?! Performance isn't terrible. I mean it is slowing but not to a crawl. Problem is that I can't have more than one or two applications open at once. So I guess I will rephrase. Performance is pretty terrible. As you might be able to tell I am not the most tech savvy guy. I don't really know much about all the details of my computer, but it is a standard macbook pro purchased in 2009. I am also not a heavy user of my computer. All I really use it for is searching the web, writing papers, and some other stuff. No major downloading or photo/ video editing. Please help. I hope there is some easy way to make it all go away, because I just started a semester long travel abroad on an island. No local mac retailer here... Oh yeah, now it is showing that 100% of my hard drive is full of "other" no music movies photos or apps. Thank you in advance for any help you can provide me.
