Hello, I'm new to the forums here. Today this window saying "Your Mac OS X startup disk has no more space available for application memory. To avoid problems with your computer, quit any applications you are not using. Closing windows and removing files from your startup disk will also help." I checked the Info on my startup disk and it says it still has 371.55 GB available out of 499.76 GB. I think 350GB+ is enough storage. What's wrong with my computer? Which files could be taking up this space and what can I do about it?
