I’ve tried repairing the permissions. Limiting desktop icons. Removing Safari’s support for ICO icons. Clearing more hard drive space. Nothing. Frickin’. Worked. I have been so frustrated by how slow my Mac Pro has been. I have 2 2.66GHz dual-core processors, 2 GB of memory, and still I was getting spinning beach balls, crunching hard drives and slow menus…and nothing seemed to fix it. I decided to take action. I was fed up! And you know what? It’s really quite simple.
