I never had any wasted space with OS X, not with Xslimmer. It did remove PPC code and everything else not needed. So this reduction in HDD space with 10.6 did not happen on my Macbook.

Another thing, how can you tell if 10.6 is running in 64bits?

Well what's your mouse? It'd help to know

And maybe it has to do with another topic rather than Snow Leopard itself

I have a Logitech G5. The way OS X handles the mouse curve acceleration is ridiculous. And I know I'm not alone: http://db.tidbits.com/article/8893 <- For a technical explanation. It's the only thing I loathe about OS X.

Using OSX on a 1920 x 1200 screen is bad enough, I can't IMAGINE using it with a higher resolution (amazingly, the Mighty Mouse is not as bad, but it's a crappy mouse tbh) .

I have a Logitech G7 and I rely on USB Overdrive too. So if I pickup a $29 upgrade, it will not let me do a clean install, so the best thing is re-install 10.5 off my original discs and then do a upgrade right after?

You can do a clean install buddy, no problem there.

Huh? Saving 7GB has NOTHING to do with counting files in base 10 instead of base 2, where did you guys get that?

Because my HDD was seen as 111GB for a 120GB HDD I had 79.9 free when I installed.

Now the HDD is seen as 119.6 and I have 90.77GB free

so

90.77

-79.9

=10.87

119.6

-111

=8.6

10.87

-8.6

=2.27

So really it saved me 2.27 GB installing Snow Leopard.

Meh I don't mind just saying.

This is an incorrect way of calculating the difference. You can't mix and match base 10 with base 2 like that.

10.5 (base 2): 79.9 GiB = 85791971737 bytes

10.6 (base 10): 90.77 GB = 90770000000 bytes

You saved 4.97GB or 4.63GiB.

Thanks. ;)

Just by looking at his calculation I knew something was wrong, but didn't feel like calculating the whole thing in-depth at this time of the day.

Edit : Found another way. Just calculate the % of free space for both situations. Then do the difference of the % and compare it to 120 GB or 111GiB. You'll see that you gain much more than 2GB. Of course giga's way is more accurate.

this little app is easy it ltells you what your kernel mode is, what your EFI is and can swith your 32bit or 64bit mode, it is made specificly for SL

I just ran the app and it still says that my kernel is running in 32-bit. It's set the startup in 64, and the right 3 boxes are 64, so I'm not sure what's going on.

Although! After I set it to start in 64, I restarted and Safari would launch instantly. It would usually take a few seconds, but it's now really really snappy. Haven't tested anything besides that, but it's an improvement. So maybe it did make a difference. I'm impressed:):)

click the about this mac to bring up your version window then click the more info button

that brings up the system profiler, click "Software" from the menu on the left, now near the bottom of the right it should say 64bit kernel and extensions YES

aarons-mac-mini:~ aaron$ systemsetup -getkernelbootarchitecturesetting

kernel architecture is set to: x86_64

aarons-mac-mini:~ aaron$ system_profiler | grep Extensions

64-bit Kernel and Extensions: No

:(

the older mini's won't work, what revision is yours?

Same thing on my Macbook Pro: Model Identifier: MacBookPro2,2

Mini is: Model Identifier: Macmini3,1

Which is the most current model

Macbook I can kinda understand but the mini not really.

this is the extent of the list for 64-bit kernel mode, the others can run 64-bit apps just not kernel or extensions

altho forcing it is supposed to work, maybe you need the hackintosh trick

So if Apple were to sell a 250GB iMac do you get a full 250GB then, or does it say 232GB and everyone argues about it.

it'll people much say 250GB except for minus the boot stuff so like 249.*

yay! My Santa Rosa MBP (MacbookPro 3,1) will boot to 64bit by default because it supports the 64-bit EFI :D

Mine doesn't in 64bit and it has 64 bit EFI

MacMini:

aarons-mac-mini:~ aaron$ ioreg -p IODeviceTree -b -n efi | grep EFI64

| | "firmware-abi" = <"EFI64">

Macbook Pro:

| | "firmware-abi" = <"EFI32">

i assume it would be 250

It won't boot it by default, but you can force it, only xserves boot by default in 64

that list also says MacPro 3,1 not MacBook Pro 3,1

Well, then I will enter the terminal command to make it default then if that's the case.

Point is I have entered the command as you can see by my top quote!

I asked this a little while back but don't think anyone responded... so making my question simpler... :D

1. Is there any downside/negative aspect to going full 64 bit? I'm on the latest Macbook Pro 17" so I'm 'capable'. How do you know if software doesn't work in x64... it just doesn't launch?

2. Is there a way to do a clean install, but also grab my iLife 09 installation from my system restore/installation disks? It came with the Macbook but I've heard upgrades are bad (that said, might just do it anyway).

Cheers guys :D

1. Yes and no, just like the Windows early transition you will most likely have to wait for the correct kext's to be written in order for some of the stuff you need to work in 64-bit kernel mode

However, because this is SL and it is a Hybrid OS you can just switch to 32-bit kernel mode do what you need to do and then switch back if need be , unlike Windows where you be re-installing the OS from scratch.

2. You can most certainly install ilife'09 from your second install disc from Leopard or time machine backup using the migration assistant, i would suggest re-installing it from the disc instead of time machine though.

just another reminder in this ever growing topic here are two app compatibility lists
