Is anyone having strange behaviour with Leopard? I have 1.8G SP G5. The fans occasionally ramp up then back down. This never occurred in Tiger. On my mini (1.25 G4) it keeps dropping my wireless link. Tiger would occasionally drop it, but Leopard ever half hour or so. Every time from wake up. I just got (and returned) a MacBook. Very similar to the mini on dropping the wifi. It came with Tiger and I installed Leopard so I could see the before and after. Anyone else with issues?
