The Lion Recovery Disk Assistant lets you create Lion Recovery on an external drive that has all of the same capabilities as the built-in Lion Recovery: reinstall Lion, repair the disk using Disk Utility, restore from a Time Machine backup, or browse the Web with Safari.

Note: In order to create an external Lion Recovery using the Lion Recovery Assistant, the Mac must have an existing Recovery HD.

To create an external Lion Recovery, download the Lion Recovery Disk Assistant application. Insert an external drive, launch the Lion Recovery Disk Assistant, select the drive where you would like more...


  • OS X 10.7 or later
  • An external USB hard drive or thumb drive with at least 1GB of free space

Version 1.0

This version works perfectly with Mountain Lion. Used it today.


We haven't had any luck on 10.8.2 (12C60).

I have a new MacBook Pro 13" 2.9 GHz that came with Lion. When the GM for Mountain Lion was released to developers I installed it on a separate partition I created.

Since Mountain Lion is so much more stable for me than Lion, I wanted to get the DMG to make my own USB key for a Mountain Lion-only installation. Good luck with that.

I had to use Apple's Lion Recovery Disk Assistant to create a copy of the Mountain Lion Recovery HD, so I could boot with it and wipe the entire HD. Before I did that though, just in case, I made one of the Lion Recovery HD.

It worked and I am running only Mountain Lion now.

I suspect that when Apple releases Mountain Lion in the App Store I may be able to get the DMG file. If I still had Lion, Apple would have to release an update to Lion to download the new installer to get to the DMG file.

I have a 500 GB portable USB/Firewire drive that I partitioned into 2 volumes: 1) A 25 GB emergency partition with a full installation of Lion and every disk utility I own (DiskWarrior, TechTool Pro, iPartition, iDefrag, etc.); and 2) a 475 GB partition containing my Time Machine backups and copies of all my software, including the Mac OS 10.7 Installer and 10.7.2 Combo Update.

So, how would an external Lion recovery disk made with this app compare with mine? Can you put any other disk utilities on it, like Drive Genius, etc.? If not, you’d be far, far better off to make one like mine so you’re not restricted to just Disk Utility to fix your Mac’s main drive!

Seems to work with only USB connected disks. This means is not very friendly with MacPros which have four internal drives.

Lion Recovery DIsk Assistant requires an internet connection to use. Which, IMNSHO is BS.

Apple, you're really pissing me off lately.

Because Lion is being downloaded from Apple servers. If you need offline installer there are many guides who tech you how to do it.

Worth mentioning this doesn't create a Lion disk out of your installer, but just creates a recovery partition that allows Lion to be downloaded for re-install.

Question: So if one was needing to reinstall from scratch (such as upgrading the Hard Drive, etc), this would work?


Not sure if you can also reinstall Lion with this but I was able to create a boot disk (Jump Drive) to reinstall should I need to using Lion DiskMaker and it works perfectly. Not sure if I can use Disk Utilities from the Lion DiskMaker one, I'll have to check although you should be able to since all the files are there. However, I was able to upgrade one of my laptops with it.


Yes you can reinstall Lion from scratch. What it does is verify that you are authorized to install it and then downloads a fresh copy to your newly installed hard drive and then installs it from there.


Moral of the story, just save that 10.7 DMG!



You can't use the DMG install method for new Macs that ship with Lion. Their UDIDs are registered with Apple and trying to install from the DMG will spit out a generic error "Lion cannot be installed on this system". You HAVE to use either this recovery utility, the online recovery method, or the recovery partition. When selected, it connects with Apple's servers and checks if you are authorized to install Lion.

I had a hell of a time swapping out the default hardrive on my new Mini with an SSD and getting Lion on it. After some trial and error, I finally got it.

Called today to verify this was the case with Apple, and yep. All new machines that ship with Lion are registered and that registration is checked at install. Apple isn't using CD-Keys, but a much more advanced system of protection inline with the MAS.

Older systems may likely have the DMG loophole plugged and also require some form of verification (so you can't just share your install DMG).


@cksum Please don’t pass off unverified statements as facts – in my case it made me vow off Apple products and sent me researching your statements. After all FreeBSD is my only alternative left after Microsoft went the activation route and Apple, according to you, won’t even let you load a local copy of the OS. So here is the lowdown:
It is possible to load the OS from a local copy on a new MBA.


that's funny ....posting a link to a warez torrent on MU


@cksum: I wonder if you completely reformat the hard drive, including any hidden partitions, if this is still the case. I bet someone wrote an article detailing this new approach of Apple's...
