Hi there, Ive got a Mac mini with a bit of an issue. Its an intel version 2.0ghz. I picked it up from a friend who used it mainly for surfing the net. It has a wireless mouse and keyboard. When I started connecting things (ipod and HTC phone) via the USB ports they worked fine for a while (maybe 10-15 mins) but then the mac acts like they are not connected. It takes a reboot for them to be recognised again. Before I go the mac my mate updated the OS for me, would this be the source of the problem or is it likely to be something much more problematic? I have now realised that the install discs are scratched as well. So I am going to buy a new OS disc. Do you reckon if I bought a new disc it would solve this or could it be a hardware problem? Thanks In advance. Mky.
