I have had my Mac for a few years now and I need to know how to speed up Mac. It has been acting slow lately and it is really frustrating. I do a lot of work on my computer and I need it to run smoothly. I have heard there are a few things you can do to it to make it run better. I hope that is true. I would hate to have to get a new computer. I love owning a Mac but just need to fix this issue that I seem to be having.
