Is InstallESD.dmg machine dependent?

[dvdborn]

Hi,

I’m making the necessary preparations to create my first InstaUp2date Lion 10.7.3 image. I’ve already created some 10.6.8 test images before learning to use InstaUp2Date.

I’ve now downloaded the Install Mac OS X Lion.app from the App Store on an iMac12,2 model.

Does Apple take into account the computer model from which you download the installer and provide you with an installer specific for this model?
Or, can I just download the installer from, let’s say an old MacBook Pro, create an InstaUp2date image with it and assume that it will also work on the latest iMac model?

Best,
David

In a word, yes. New hardware will probably be forked, and there are some reports of older hardware wanting particular builds, but I haven’t confirmed those symptoms.

Hi Allister,

Thanks for the quick reply.

That’s what I suspected but I was hoping I’d be wrong.
Too bad that we don’t have a list of all the different versions that Apple supplies.

(oops, I was saying yes to your second question). 10.7.3 is universal, even if you download it from Internet recovery(as described in a post here on AFP548 from last year), as long as the hardware is not recognized by apple as one that shipped with Lion server. There is also a knowledge base article listing what build shipped with what machine, but as of this moment no other hardware requires a special build, and InstallESD.dmg can be acquired from any channel.
Sorry about the mixup,

Allister

Allister,

Thanks for the clarification.

Cheers,
David
