I know this is an old mac and is expected to have problems but I have a mid 2009 MacBook Pro and whenever I start it up it will most of the time go to login, I will put in my password, then it goes to my desktop. Now, there a variety of things that happen, it could not even load my desktop at all and it will just freeze at login, or it will go to my desktop, show my background but not load the bar on the top of the screen or my apps or the bar on the bottom of the screen, (I forget its name). Or, it will start up everything fine but when I try to start or click anything it will freeze up and show the spinning pinwheel for FOREVER. Or it could load everything great and i can start up google chrome and start watching markiplier and it will eventually freeze google chrome, spinning pinwheel, try to quit google chrome, and that doesn't work, try to force quit, and then force quit freezes and then the finder freezes, and everything goes to sh*t. Also it reacts the same way during safe boot. I just tried safe boot and now the MacBook won't continue on from the screen with the apple logo...please help...it worked fine before....
