Hi I am totally new to Mac OS, could like to check with you guys. I planning to buy a MBP, as i look at the specs, MBP can support up to 8GB of ram (2 x 4GB), the question is, i knew that that for MS windows, only 64bit can support anything above 3 GB, how about Mac OS X? say if i do purchase 2 x 4GB, can OS X detect 8GB? or are there an 64bit version instead? As i am planning to use VMware Fusion to have a VM running windows concurrently, therefore if OS X can support up to 8GB of memory that will be great!. Appreciated you guys replies. Thanks!
