I saved about 21GB of space. Boot-up time is about 8 seconds faster, shutdown time went from 12 seconds to 4 seconds. Most all applications only launch a second or two faster than they did under 10.5.8.

With the exception of 1Password not working until I download/installed the beta of version 3.0, and a loss of license info for Snapz Pro, all apps worked perfectly.

The only thing I did after the upgrade was to turn on the 64-bit kernel. You can download any number of apps from MacUpdate to do it, or just type the command in the terminal.

I thought I read somewhere that holding down the numbers 6 and 4 while booting up would enable 64 bit.

Still so far, so good.

Looks like BootCamp got upgraded to 3.0, so those using it may want to update your drivers ... it took me a couple tries for everything to take in Windows 7, but the HFS+ support alone is worth the effort. Now you can access Mac volumes "natively" w/o any third parties -- nice!

Also, it looks like Flip4Mac still works with QT, although I have to drag the .wmv to the QT icon in order for it to work -- just double-clicking a .wmv file generates an error claiming you have to have QuickTime installed ... so a little buggy there, but nothing crippling =)

open up your terminal and type this:

ioreg -l -p IODeviceTree | grep firmware-abi

it'll tell you whether you're using 32 bit or 64 bit Mac. and this is how that would read in the terminal app if you can enable the 64 bit side of snow leopard:

"firmware-abi" = <"EFI64">

I tried that on my 2 yr old MacBook and got nothing.. what gives ??
I expected EFI32 to come back, I'm pretty positive it's not 64...

Thanks all for your comments... guess I need to bite the bullet and play in the snow.

check about this Mac
core 2 duo is 64 bit for Macbooks
core duo is not.

i believe.

actually, the more i read up on this, the more i think that staying in the default 32 is the right way to go about things for now. until apps are really ready for 64-bit, many still use the 32-bit kernel extensions (or kexts). having your make switch to 64-bit means that the 32-bit kexts will not work in 64 bit mode. i think developers should probably be the only folks going with 64-bit for now (and folks who are just sure the apps he/she uses are not using 32-bit kexts). for example VMware Fusion uses 32-bit kexts.

Thanks FSM, I will.

Wha! That might not sound like much to some peeps, but . . . .

I just fired up NeoOffice (yes, I have to work on a Saturday, sucks) ~ So, how's NO working for you Snow Leopard types? Any problems? It was on the list that Swatty linked us up with, granted with the caveat that only one user had reported a problem.

'K. Back to the trenches. [heavy sigh][/heavy sigh]
