I am constantly getting the dreaded beachball. I have done all the usual things to try and speed up my computer. I have deleted my cashe, cookies, shut down all things "running in the background", I have even resorted to PC strategies such as restarting my computer or some form of "defragmenting." I have run memory apps to free up memory and have plenty of extra memory space and storage. What can I do to get my MBP to stop freezing? Help!!
