Firmware update broke my original Clamsheel iBook Mac OS 8.6 compatibility.


Recommended Posts

Dear 68KMLA users,

 

First time poster, long time lurker (10 yrs).

 

i have a original orange iBook g3 clamshell computer that used to boot to Mac OS 8.6 just fine, yesterday I found out that there is a firmware update available.

I did the update and it broke the Mac OS 8.6 compatibility. whenever I boot to 8.6 it just shuts down right when the desktop loads, even when I boot from the original restore disk witch worked just fine before the update.

mac OS 9 has no trouble booting...

 

anyone know how to downgrade the firmware?

 

Thanks!
