1. I ran Onyx and it froze during deletion of Trash. Had to force shutdown the machine (not good for it I know). Then I ran Disk Utility and it came up "Macintosh HD volume was found corrupt" and told me to reinstall the OS from the installation disk.
I haven't got the installation disk and someone on another thread told me to download OS X Lion as it has a Recovery function that you will be able to do a fresh install after you create a bootable OS X Lion using a USB stick? Would this be the best option? How big would the stick have to be? I have an 8GB one.
2. Also when I start my machine for a while now 3 pop-ups say "/Library/StartupItems/HWNetManager","/Library/StartupItems/HWPortDetect","/Library/StartupItems/StartOuc" have not been started because they do not have the proper security settings.
I back up using Time Machine back-ups but read that to be really safe I should use SuperDuper too. But these messages never go away even though I just downloaded the 10.6.8 update and I don't know how to fix them.
3. I've been having trouble with my Airport connecting to my Thomson T585v7 router and I read on the net that OS X Lion has a few Airport problems. What should I do?
