See my post above -- same thing happened to me and I had to do an archive and reinstall using system disks.daliscar55 said:ive just downloaded the new version of tiger, 10.4.7 and my mac wont go past the grey apple screen. just hanging on the logo, nothing happening for about 1 hour. it wont let me start up with the tiger install dvd by holding down c whilst dvd in drive (has to be in external dvd dive as internal is on the blink). i havent had any problems with an OS before so any help would be greatly recieved...........
I tried booting into secure mode -- that is, doing a hard shut down, power up and holding shift when chime sounded. I held it for about 5 minutes and no go. But someone on another board said that he held for 10 minutes and eventually it booted into secure mode.
This is what I did and it worked but took forever:
!. Find system disks -- you need both.
2. Get disk one ready in drive.
3 Power up, insert disk and hold C when chime sounds. It will boot off system disk.
4. First go to disk utility and then verify your hard drive, repair if needed.
5. Then go to installer and do an archive and reinstall -- this takes a long time and you need both disks.
6. After this completes and restarts you should arrive at login screen.
7. Log in and then immediately do a repair permissions and restart.
8. Now download 10.4.7 combo updater from apple website -- Do not use software update. Go to apple website and find combo updater. Install. REstart.
9. Repair Permissions again and restart.
10. Run software update to get updates to mac programs.
11. REstart, repair permissions again and restart.
If you use OnyX, run maintenance which includes repair permisssions, rather than simply repairing permissions above.
This worked for me but took over 2 hours. Things are running fine today. No problems
