Clean Install Lion...
Hi,
Is going from SL to Lion an "upgrade"?
Can I "clean" Install Lion without SL?
Thanks.

As far as everyone is aware, currently, the only way to upgrade/update to Lion is via the Mac App Store and this will need OS X 10.6.8 to do this.
Lion upgrade questions and answers...: Apple Support Communities
Apple - OS X Lion - Sign up to be notified when Lion is available.
Can I "clean" Install Lion without SL?
Not according to Apple. The latest version of Snow Leopard is required.
Apple - OS X Lion - Get Lion in July. Only from the Mac App Store. Lion requires an Intel-based Mac with a Core 2 Duo, i3, i5, i7 or Xeon processor and 2GB of RAM. The Lion upgrade can be installed on all your authorized personal Macs.
Is that why it says '... corrupted or tempered during download' when I tried to install in my Air, 10.6.7.
You should be upgraded to 10.6.8 before upgrading.
Oh no... Now I've removed the Lion install icon from the Dock. Can't seems to click install in App store as it appears as 'Installed'...
Has done the upgrade to 10.6.8.. still same problem can't install prompted '...error and tempered during download...' Thnx for suggestions.
Performing a clean install of Lion is easy once you create a Lion Boot Disc. How do I create a Lion Boot Disc, you ask? That's easy too! Just follow these instructions: http://www.macrumors.com/2011/07/18/make-an-os-x-lion-boot-disc/
The fact is that the Lion installer is packaged around a bootable disk image that can easily be burned to a standard 4.7GB DVD. With the boot disk you can run disk utility to erase your Mac, and then clean install just like you could with every other version of Mac OS X. Just don't forget to backup all your data!!! 😉

hi
I've got some questions and I'll be really pleased if someone can clean up my mind about them.
I've heard about a way to 'jump' the Snow Leopard 10.6.x version from Leopard 10.5.8. I mean passing from Leopard to Lion modifying a file located in /System/Library/CoreServices, it's only to change from 10.5.8 to 10.6.x
or whatever in the file 'SystemVersion.plist' (I think that's the name of the file). But my question is if the files I've got in my Macbook 10.5.8 (all the files, photos, applications, music, programmes... definitely EVERYTHING) are compatible with the new OS X Lion. Is that true? Are there any problems with that?
I know the better way to do it, is to create an USB or a DVD with the OS X Lion Installer, then to restore the computer (delete everything), and start the computer pressing Alt and selecting the USB where you have the Lion.
