Am I able to install Lion from 2011 macbook Air?

No. You'll have to buy it from the Mac App Store. It's £20.99

 

Awww boo. So I've got a licensed copy of Lion on my new Air, but I have to buy a licensed copy of Lion if I want to install it anywhere else.

Boooooooo, squeezing them til the pips squeak

 

The copy of OS X that comes with Macs is licensed for that machine only. This has always been the case--the restore media only worked with that particular model.

 

ok thanks

 

The above is the way it used to be, but I do not believe that is the way it is now. Supposedly, Lion comes with an authorization for all your macs.

It was discussed during the Keynote.

I do not know if that means you can take the version off of your Air and install it to others. This may only be for the version downloaded off the apps store. I would look further into it.

 

So you're buying a $1000+ laptop, but you can't spare $30 for a family license for an OS? /firstworldproblems

 

Want to spunk another $30 up a corporation's chuff for something you've already got, go for it fellah. Not for me. ps this isn't twitter, you look like a fanny.

 

There is a distinct possibility that the MBA may come with a USB key version.

 

Which will be a restore drive for that MacBook Air only. The OP will still have to buy Lion to put it on his other Macs.
