Would appreciate help -
I have an old MBP mid-2009 shipped originally with 10.5.7 Leopard, currently running 10.6.8. I restarted recently and found a kernel panic on startup. I have tried booting in safe mode (unsuccessful), recovery mode (unsuccessful), reset NV-RAM (unsuccessful startup) and from an OSX install disc ("unable to install OSX on this computer"). The last option yielded an actual startup screen ith language options and a box offering the option of restoring from a TM backup (I don't have one as I did not have any important data on this machine). So broadly the machine works but never gets past the grey screen with the apple logo and the time wheel.
I have another 2 newer MBPs at home and considered using target mode to resuscitate the oldest malfunctioning mac. BTW I can't eject the OSX disc from the bad mac.
Any advice on how to revive my old Mac? I'd like to keep using it as it was fine yesterday.
