Sorry if this is not the right area. However I would like to purchase Snow Leopard when it comes out of course. I currently have Mac OS X Leopard. I wanted to know if I could do an Upgrade of Snow Leopard rather then a complete/fresh install of Snow Leopard.

If an Upgrade is available, Will it be as good as a fresh install? And will it still minimize the amount of space of the operating system?(as I heard snow leopard would do this), And will the improvements to the speed and architecture of the system be as good?

If possible, explain what an upgrade actually does? (Does it remove the old operating system and put the new one on keeping user folders intact and applications intact? Or does it indeed just change files)
PS: I am tech-savvy. So explain in detail if you want!!
Thanks!

If you are on a Mac, then definitely. Pop the disc in, open the installer, follow the instructions. It selects the upgrade option automatically and will save your apps and all of your data. Once you are booted into Snow Leopard, everything should be the same except the OS you're running

I have a MacBook Pro Late 2008 Model..

Thanks for the quick reply! Wasn't expecting one that fast.

Will it run as well as it would as a clean/fresh install?

Oh and just adding onto this:
Has anyone used the Developer Preview to test this? I know it can change from developer-retail but still

If possible screenshot the installer option to upgrade? I'm just curious atm.

Best way IMO is to install to an external drive, copy all the files you want over, format main drive and then use CarbonCloneCopy to copy the External install to the internal

I ever upgraded my installs directly, there are upgrade options to use your actual instalation, do a new one preserving the Apps, and the Erase and Install.

i am currently using a macbook 13' bought in feb 2008. i would love to buy snow leopard but my only concern is losing my applications.. does the install keep the current applications..?? especially as they are all 32 bit..

Your applications are retained if you do an Upgrade.
Everything is lost if you do an Erase & Install.
If you do an Archive & Install, than you will still have all of your old data stored in a "Previous System" folder, which you can drag your apps and data back into your main hierarchy.

thanks a lot..

is there any difference between the snow leopard upgrade and a standard install of snow leopard? one of the things that i'm excited about in snow leopard is the smaller memory footprint... will this actually be the case if i simply upgrade from leopard or will i need to get a full version of snow leopard.

also, will it be possible to install directly from the upgrade disc or will i absolutely need to have leopard (which i already own) installed first?

thanks

What about with hackintosh, fresh install, does it totally screw up the kernel/kexts?

On a hackintosh, if you did a erase then install, then all your kexts should be wiped?

But what about with an upgrade? Would I be able to just buy the disk (its not that expensive), and upgrade a hackintosh without screwing it too much if it is a vanilla install?

Has anyone tried upgrading yet? Are all the kexts retained? Or have you had to reload them?
Are there any kexts that do not work due to 64-bit issues or other issues?

SRY, thats what i meant.

id like to know too if you could upgrade rather then erase and install! that would make everything alot easier ha

Hey please for fast replay. I can update without recodring it on dvd.?? i don't have DL-DVD-R and 8 gb pendrive so can i just mout install dvd on leopard and start update?? or i need real dvd??

All you can do is try and mount the image and try to install =D

I have a powerbook pro 2.16ghz intel core 2 duo. I also have an installation disk for snow leopard. I want to install snow leopard over leopard (what I'm currently running) - If I archive and install, will the archive take up extra space? Is there a way to just install snow leopard as an upgrade and keep all data and apps? I don't have the disks for my apps anymore, I've had them for so long on my computer and I've moved overseas twice!! I have no idea where they are and can't afford to lose the installed apps.

I haven't done an upgrade since leopard and that was ages ago.

My MacBook came with the Snow Leopard disc, but had Leopard preinstalled.

I just booted into 10.5, inserted the Snow Leopard disc, and did an upgrade, no problem.
