Had a great amount of help from my last message post (having installed 10.2.5 earlier in the summer, not using it and coming back to it a week ago, nothing just a grey screen with the apple icon - no rotating icon) and I've tried all suggestions helpfully given below ...
Run disk utility. When the installer comes up, click on the "installer" menu, and select run disk utility. then verify both the disk and permissions. repair as needed.If this doesn't work, try using the single user start up mode. hold down apple and "s" after hearing the startup sound. it will start you up on a black screen with lots of white type. when you get to the prompt, type in: fsck -y press enter, let it check the directory. when it finishes, type: reboot
... still no luck, can't even get into single user mode, just the grey screen and icon again, no rotating icon.
Has anyone got any more suggestions besides reformatting the hard drive. Can I reinstall OSX?
On another OSX issue - I was having problems with my Mac at work and was told that you have to leave between 15 and 20% of your hard drive space free for UNIX to operate fully!!! Greedy or what!
Anyway any and all help would be much appreciated ...
