Hi guys,

I have an early 2009 iMac (iMac9,1 20" C2D 2.66MHz) and I've been trying to install Mountain Lion. I've made a USB Key with the image and I'm installing on to a empty partition. The installer runs fine, however the time remaining is never higher than 4 minutes, usually switching between 2 and 3 minutes. The progress bar reaches the end and it'll keep alternation between 1 and 2 minutes remaining. The bad thing is it always pops up and error stating:

"Can't download additional components needed to install OS X"

The only option available to me is Restart. The iMac is online as it's wired and I can use Safari from the Help option to visit any site. I've also connected to my WiFi network with no joy.

Any ideas?


Andy

Use this (http://forums.macrumors.com/showthread.php?t=1401529) guide for creating an installer with the components that are missing.
However it wont create a recovery partition. This (http://musings.silvertooth.us/2012/03/restoring-a-lost-recovery-partition-in-lion/) guide has a script that will create one for you.

Hey. First time poster on MacRumors.

I was struggling with this problem for an hour or so, and managed to solve it by simply reformating my USB drive using Disk Utility and running Lion Diskmaker (http://blog.gete.net/lion-diskmaker-us/) again.

Hope this helps someone.
