A system restore CD then from about 10.4 a restore DVD. One thing that made it easier from around os 8.6 onwards (maybe higher) was the inclusion with each machine of a circle of plastic worth about 12c. I haven’t tried it, but will when the (re) download stops.Īpple: I’ve been maintaining your various Power/Mac Books at various universities since 1995. I’m thinking: for Frank’s DVD solution (thanks Frank), should we/can we format the single partition in the ‘GUID’ Bootable format option available in disk utility? I’ve not tried this but: When I bought this MacBook Pro about 2 weeks before the Retina and new version were released (my lack of research), I made a Lion bootable USB Flash using the App for this from the Apple web site. So I’m currently redownloading it and going to try to make a bootable disk.

Safari is driving me nuts and a minor niggle is it constantly loses the link between the dock icons for Aperture (another genuine recent purchase), Mail, Contacts/Address book and one more I forget. (If the author here doesn’t like that I link to another site, please feel free to simply delete this) You can see that everything was able to fit 😉 This will copy all the content of the apple install dmg into your new image. So Disk Utility see only the total capacity of the dmg (4.75) and tell you you cant burn it to a normal dvd.Ĭp -Rv /Volumes/Mac OS X Install ESD/* /Volumes/OSX Lion Mountain DVD Now, the problem is Apple did a dmg of 4.75gb and the used space in it is only 4.3gb. You should have 2 drives on your desktop. If you have a normal DVD, you can create an empty image of a single partion dvd with Disk Utility, name it OSX Lion Mountain DVD. Someone posted the following on another site in the comments: That said, it’s always nice to have a disc or flash drive handy in the event you need to perform a clean install. When you install Mountain Lion, you’ll have a recovery partition on your drive in case something goes wrong.

Click the Options button and choose “GUID Partition Table” - this will make the drive bootable and formatted correctly for the Mac.Select the Partition tab, select “1 Partition” from the dropdown menu and choose “Mac OS Extended (Journaled)” for the format type. Insert the disk and select it in the sidebar in Disk Utility.


If you’re burning to DVD: insert your disc, select the DMG file in the sidebar, and click on “Burn”.Open up Disk Utility from your Applications > Utilities folder and drag the DMG file into the sidebar on the left.Head to Contents > SharedSupport and look for the file called “InstallESD.dmg” Find the installer in your Applications folder and right-click on it then select “Show Package Contents”.Download Lion from the Mac App Store - but don’t install it yet (because of the disappearing installer issue noted above).The steps for burning Mountain Lion to disk are essentially the same as the ones used for Lion:
