[QUOTE="rubaiyat, post: 1626880, member: 240393"] OSX likes 20% of the hard drive to be free. If you have less than this the amount of paging and rewriting to disk increases to the point your Mac can grind to a crawl. Simply back up as many non-essential files to an external WD Passport hard drive, or replace the internal HDD with a much larger one. Swapping them in all but the very latest Macs is a simple procedure, you just need some small screwdrivers for the tiny screws. A SSD drive is just as easy and doable, just the capacity will be much smaller for your money and if your HDD is too small now, an SSD will be even smaller so still be paging, just paging faster, not a solution. You can determine the S.M.A.R.T. status of your selected internal hard drive at the foot of Disk Utility. This is no guarantee of predicted failure however, it just may give some warning. [/QUOTE]
