I have the 2.0GHz 1GB Macbook, and Id like to upgrade to 2GB. Ive heard of memory upgrades voiding the warranty, if you use the wrong sort I have the 3yr applecare plan, so Id rather not void it. Will this memory from Kingston be ok? http://www.ec.kingston.com/ecom/con...fo.asp?root=&LinkBack=&ktcpartno=KTA-MB667/1G I can source it for pretty cheap (especially compared to AppleStore). Can I install it myself without ruining my warranty? Has anyone else upgraded memory themselves in a Macbook? I build PCs at work, and have worked on a couple of laptops the Macbook looks a bit tricky to get into but Im sure Id manage. Id just like to know if its okay to do a memory upgrade? (I think Ive heard of people removing the memory again if they ever send the Mac back for repair). Cheers.
