If i purchase a new mac mini,can i download a image of mountain lion from online store and then make either a dvd (using external dvd) or flash thumb drive...for free?

Yes i know it has built in recovery using Command-R...just would like to make my own media copy so don't have to wait on internet dl if needed in future.
 
I had this same question for my MBA, I came to the conclusion that no, you can't make a boot disk. As luck would have it I had to buy the ML upgrade for my MBP that I'm passing onto a family member. I made two boot disks, problem solved.
 
If you can get the file from the App store, you can.

Find the file Mac OS X Mountain Lion Install ESD from the App Store.

Right-mouse click, choose 'Show Package Contents'

Inside the package contents you will find the dmg file, copy that and mount it using disk manager, from there you can burn a DVD.
 
I know how to make file...what I'm wondering is...if i go to online store and use my id from mac mini purchase will i be able to dl mountain lion for free,or will i have to pay for copy???
 
if it's a brand new 2012 mac mini you have to do it this way: http://hints.macworld.com/article.php?story=20110831105634716

i would recommend this for all new 2012 mac mini owners - internet recovery takes forever

& yes it works for mountain lion too (article says lion), & rumor has it os x 10.8.3 will be a unified installer that should work for all ml-capable macs, once available you can just do this: http://arstechnica.com/apple/2012/07/how-to-create-a-bootable-backup-mountain-lion-install-disk/ like you can for other/older macs

been there done it myself, you're welcome

If you purchased ml through the App Store then yes you can sign in to any mac and download it.

You can't download it if it was on your purchased mini.

Easiest way to tell is click the purchased tab in macappstore

until ml 10.8.3 is released that method won't work on 2012 mac minis or new mac book pros - the app store download is 10.8.1 or 2 & if you boot from it on a newer machine you will get a grey stop sign when you try to install.. the only way to install from usb on newer machines 'today' is in my post above (i spent 2 days last week going through this myself)

And do you have any idea why that is? Some way Apple has to avoid you from downgrading the OS?

Thank god I found this. I was gonna format my new Mini (waiting for it, it's "Out for delivery" now) when I got it. I was gonna do it because I'm swapping the 4GB memory installed for 16GB I bought yesterday. Do you think it's needed?
 
my assumption is it's not necessarily intentional - it's just the app store versions of os x don't always have the latest hardware patches/firmware/drivers as the mac os is on a different release schedule from the mac hardware

& just to clarify the instructions posted above in this link http://hints.macworld.com/article.php?story=20110831105634716 allow you to extract the installesd.dmg (actually from the same files used for internet recovery) to create a local usb installer (using the usual manual method for creating a usb or lion disk maker)

you can of course always do internet recovery on any new mac... but, if you want the flexibility to perform quick rebuilds/re-installs without taking 2+ hours each time a local installer is the way to go
