While I don’t know what your problem is, I can provide some simple guidelines and explain how and when to use each fix.
I want to teach you the proper way to troubleshoot computer slowness so the next time you know how to tackle similar problems. I assume you understand that I was joking. The fix won’t work of course, because you will forget to mention that the RAM was upgraded before wiping the screen. So everyone should try the same solution. Then whenever someone complains about the slowness of her Macs, you can authoritatively claim that once you wiped the screen, your Mac stopped freezing. If you are lucky, after trying ten various things, one will eventually work and get everything fixed. You can go over the entire list and keep trying all suggestions hoping that one of them will be a silver bullet. If you spend enough time on forums, you will find at least 25 different hacks which people will suggest you should try. Back then we always complained that our computers were slow, but even today I still hear the similar complains. I’ve been developing software professionally for more than 20 years. It keeps freezing! My Mom called me about her MacBook Pro, which was running very slow and she asked me to help.
