Generally I avoid OS upgrade but this time I am giving it a try in a production machine.
Upgrading from Mac OS X Leopard to Mac OS X Snow Leopard Developer Preview on my MacBook Pro.
My colleague tested the upgrade on a MacBook Core Duo and it went smoothly.
I’ll see if the upgrade went smoothly on my MacBook Pro Core Duo.
P.S. I ordered another 320GB 7200RPM SATA hard drive for the MacBook Pro. It is still much cheaper than the 500GB 7200RPM notebook hard drive.
