Install Question

[Maclver]

If I download mavericks on my MacBook Air can I use that same install for my MacBook Pro retina? Or does it require a download from the specific machine?

You can use that same download. Just make sure you keep a copy before you install on the first machine because the installer app deletes itself once it's done.

Or better still, make a bootable USB first and use it to install on both machines:
