SO I have this iMac spawning threadage as you see! Latest news is it needs the DDR2700 with 184 pins I think,.... and for that max I can get is 512, also 256 is available still. Will either be enough with the 512 onboard already for OSX - just Geffy recommended I took Panther and I am wondering. Also there remains the question of if it will take ANY to add to the 512 and also boot to the install.... It is not playing with 9.2 and there's no password access fro admin - I do not want to mess with guidelines but password recover looks the next avenue - anyone know anything on that score?
