Hi all, My girlfriend's 1 year old MacBook has suddenly started acting up. Applications that have always been fine, are now crashing before they even start to load. Photoshop crashes during the splash screen, as does OpenOffice. I have uninstalled and re-installed both with no joy, and the moment I realised something more sinsister was up was when I tried to install LibreOffice, that crashed out too. I'm not very familiar with OSX so have no idea what to try beyond the good old uninstall/re-install method which hasn't worked. I've also just downloaded ClamXav which is running now (I just selected the hard drive and clicked run, it's taking absolutely forever, god knows why, it's a Core 2 Duo CPU fwiw and is usually quite nippy) but so far hasn't found anything wrong... I'd really appreciate any advice or suggestions, thanks!
