My MacBook gets stuck but still has 44 GB of storage left My MacBook has 125 GB storage space (other 125 GB is for Windows). It still has more than 44 GB available but it gets stuck every two hours. I have tried all the methods I can find and have deleted what I can delete. But it still doesn't work! Now I can't write my final paper in Word!


When it starts up it still has 44 GB available


Less than 2 hours later it would be like that

And then all the application paused and I have to re-start.
You have  memory leak somewhere and it's causing your system to essentially supplement ram with hard drive. 

Open activity monitor, go to the memory tab, and sort by usage. See if you can figure out what program or combination of programs is gobbling up all your memory. 
Also that same tab will show you used memory, swap space, etc.
