Hi, I'm running a Macbook 13", 2 Ghz, Core Duo, 1 G Ram. Since installing 10.4.10 I began experiencing two unpleasant things: 1) My computer seems slower - apps take forever to load, more colour wheels, etc; 2) My comp has unexpectedly restarted several times. Is anyone else experiencing this?
Also - as part of the 10.4.10 upgrade was a superdrive upgrade. This didn't work - it said it found nothing to upgrade - at the time, and has since appeared every time I restart to tell me there is nothing to upgrade. This is nuisance - should I be worried about it? What can I do to get rid of it?
Many thanks.
