My first generation (Rev. A) MacBook Pro (Core Duo 2.0 GHz Intel 32 bit Yonah) has starting to slow a little. The 100GB hard disk is full and I can’t add any more RAM (2GB’s maxed out) but swapping in a bigger faster 7200 RPM laptop HD drive (say like a Seagate Momentus 7200.3 320 GB) and upgrading the mini-PCI wireless LAN card to 802.11n will get me by. As I recall, Apple took about a year and a half to upgrade to the Core 2 Duo chipset with 64 bit capabilities and even then Leopard didn’t come out until Fall 2007. I was an early adopter and I’ve been pretty happy with this machine. So now I’m looking to either stay with OS X 10.4.11 or possibly go the whole hog to 10.5.5, either way I’ll need XP Pro SP3 for CAD software using either BootCamp or rEFIt as a bootloader.
In Leopard with Time Machine data backups should be seamless, my only concern now is application compatibility and system stability. Z’s white MacBook 2.2 Core 2 Duo came loaded with Leopard 10.5.1 and seems to have stabilized in 10.5.4 (though I think it does need more RAM). From what I’ve read, somewhat like Vista, Leopard has a basic “footprint” of 512MB, so really 2GB is the minimum you need in practice with multiple applications running. Tiger apparently has something like a 128MB starting point.
I took my first 3D rendering class in SolidWorks today at NYU. It seems pretty cool. NYU sells an educational copy that should work under XP and the MacBook Pro supposedly works alright with it. We’re going back to Jimmy’s No. 43, I’m excited.
