I Basicly have 2 questions. 1. I have a slightly lighter patch in the bottom left area of my iMac screen that is mainly visible when there is a black but still backlit screen. Also about 3 "shiny" pixels, i am not sure if they are dead but they change colour from different angles. Is this worth talking to apple about (Replacement/Fixing). It is an 07 Aluminium iMac, i havn't done anything as i hoped the problem would just go away but it is really annoying. 2.My iMac is also getting slower and slower to boot up and shut down, now it takes about 40 Seconds when befor it was much faster. I have used Onyx to try to clear this up but it is still slow i also have lots of Hard Drive space so that shouldn't affect it. Is there anything i can do. Thanks.
