thanks for your prompt reply.
what about full version? if i bought a full version of mac os 10.(?) then i could upgrade my old mac? where can i find a mac os x? i don't need a most updated 10.5 as it might be too much for my hardware. and any site of reference for step-to-step upgrade procedure?
thanks again from liza, sheila or whatever. hehe
p.s. my old mac is at least 6-7 yrs old? how can i check the hardware of it? i am an absolute idiot when it comes to mac. sigh
