My 8100 is playing up...... again! I installed Mac OS 7.5.3 on my mac and had to install the powerpc enabler for some reason although apple say that it doesnt need one for 7.5.3. Wierd. Anyway, Everytime i go into the Monitors control panel it says it isnt compatible with my macintosh, why?? I need to change the res and colour depth. Help me!
