    Unhappy Why is my MacBook's memory sporadically changing from empty to full and back?
    My MacBook has been having this problem for a couple days now.
    Before that, my hard drive had estimated that it had several GB's of memory left, and then suddenly whenever I use the internet, watch a movie, or look at youtube videos the number starts dropping rapidly.
    I deleted 3 movies and some music to try and help, but it did nothing.
    I really don't have much saved onto my computer, and certainly not enough to have filled the memory disk. I'm confused because I haven't downloaded anything lately.
    Right now it says that I have 1.02 GB of space left [which is less than I should have] but when I watch youtube for 5 minutes that drops down to 877 MB of space. Then when I closed youtube it shot up to 1,004 MB.

    what is going on?!

    It's your cache file. As you browse the web, watch online videos, etc, your computer caches the data to make it play back or browse smoothly.

    so is that something that has always been happening, and i'm just starting to notice it now?
    the problem is, lately when I've been using these programs for a while the memory reads so low that it sends me warnings about the Start Up Memory Disk being close to full. I'd never received those messages in the past.

    You really need to delete some stuff off your hard drive. You need way more than 1 or 2 gb to have it run properly.

    I have been deleting things though! I'm confused because before all of this started happening, I think I had like 7 GB of space. Then it suddenly dropped to 1 with no new downloads.
    So I started deleting large items like movies, and that made absolutely no change in the estimated storage space.
    I guess I'll just keep deleting things...

    Your memory refers to something entirely different than your available hard drive space. As they said though, cache, and not enough space left probably.

    There are people around who will tell you that you need to keep 15-20 GB free. With todays larger drives that is not hard to do. When the hard drive space gets as low as yours is and things are cached, you will run into slowdowns. How much RAM do you have in the Mac? RAM, Memory not hard drive space.
