Hi All, Okay had my first 'glitch' today, but being a mac n00b i realised I didnt actually know what to do when things go wrong (unlike with a pc). Basically I was watching a vid in VLC and a vid in Quicktime player. Afterwards I deleted the vid but couldnt empty it from trash as it said it was still in use. I had completely closed both players so I was confused as to why it was saying this. I decided to reboot the mini but on doing so I was faced with a white screen. I turned the mac off via the power at the back and then on again. Same thing, white screen. I started searching websites via the iPad in a bit of a panic, but while doing this the mac eventually showed the apple logo and it began booting up normally. Its now running okay (havent rebooted it again though), but can anyone offer some basic tips on what to do should this happen again but not boot at all. Thanks in advance! EDIT: Hmmm just rebooted again, seems I am getting a white screen for an extended amount of time before the apple logo shows each time now.
