Hi, I know this question has been posted many times but I don`t find any solution for me in the old threads. I have a 1 year-old macbook, 2GB memory, 160GB disk space of which 30 are free. Since a while everything slowed down, start up when I switch it on, starting programs, loading of webpages etc. I cannot identify when this started and what I installed or changed to trigger this. I performed "repair disk permissions", which changed nothing. I want my old, beautifully performing macbook back, what can I do???
