MacBook Pro will only start in 'safe' mode, why is this?
2007 MacBook Pro Intel 2.33GHz 17in 3GB RAM
I have a 2007 MacBook Pro that will start normally with the chime and Apple logo. I also get the gear wheel underneath but then that screen just goes to a blank grey screen and nothing further happens.
I tried to reinstall using a retail Snow Leopard from DVD but starting up using the 'C' key ends up with the same result.
I then used my iMac to install 'Lion' onto another hard drive I have and installed that into the MacBook Pro. Yet again the machine displays the same behaviour.
The only way this machine will boot is in 'safe' mode (starting while holding down 'Shift') Once it had booted I used Disk Utility to repair Permissions and noted that it appeared to repair lots of files relating to the display.
I also plugged in an external display and that worked fine, so I rebooted normally with this also connected and again got to the white/grey screen.
I have two RAM chips - a 1GB Samsung and another 2GB Kingston. I removed the Kingston and tried just with the Samsung - no change. I swapped out the chips - no change.
I have again tried to boot from another installer DVD - this time 'Snow Leopard' and I just cannot get the machine to complete start up.
It's doing my head in!!!
Это хороший вопрос?
