Oct 16, 2014 8:30 AM in response to Csound1by Kingoftypos,I have Yosemite installed on a 2012 Mac Mini. If I were to do Internet Recovery, it will downgrade me back to what was original installed, which was 10.8 Mt Lion.
If I do the regular recovery, it reinstalls Yosemite.
The rules are outlined in this article. Just below the graph. OS X: About OS X Recovery

Oct 16, 2014 8:48 AM in response to Ghost_Riderby Csound1,That machine may not even have Internet Recovery abilities. Machines that shipped with Lion were the first (some 10.6.7 machines may have had a retrograde firmware update to add it)
But if you keep getting Yose then I'll assume that you don't have IR and are seeing the (expected) standard Recovery partition.

Oct 16, 2014 8:39 AM in response to Loner Tby Ghost_Rider,Hi Loner T. Yes my MacBook Pro is in the list and already had the MacBook Pro EFI Firmware Update 2.5 applied years ago.

Oct 16, 2014 8:41 AM in response to Csound1by Ghost_Rider,Hi Csound1. Yes my MacBook Pro already had the MacBook Pro EFI Firmware Update 2.5 applied years ago. I do get the real Internet Recovery if I want it. You know, the spinning globe and the download before you get to the recovery screen.

Oct 16, 2014 8:42 AM in response to Csound1by Kingoftypos,Oh sorry, I purposely posted to your name because I was going to write it as if I was agreeing with you with the above. But when I read it, it didn't seem like I was. So I deleted the quote from one of your posts and forgot that the website was pointing to your name.
To ghost_rider, here's a link to a list of Macs that can accept a firmware like update to do Internet Recovery. Computers that can be upgraded to use OS X Internet Recovery
Now what does that mean for it wanting to install Yosemite? You've got me on that one.

And when you use Internet Recovery you get Yosemite?

Oct 16, 2014 9:28 AM in response to Csound1by Ghost_Rider,CSound1, FWIW my MacBook Pro is an oldie but goodie. Purchased October 20, 2010. It even has gray hair like its owner.

Oct 16, 2014 9:31 AM in response to Ghost_Riderby Csound1,How odd, and how undocumented is that. I have no Mac of that particular vintage (execpt for a MacBook) so I can't test, but I have not seen that before (and as Yose is prerelease) I am very surprised.

Oct 16, 2014 9:32 AM in response to Ghost_Riderby Csound1,That suggests that the hair has remained in place, small mercies

Oct 16, 2014 9:39 AM in response to Csound1by Ghost_Rider,I have a white MacBook running Leopard (10.5.8). Should I give it a try? heheheheh

Oct 16, 2014 9:46 AM in response to Ghost_Riderby Csound1,Mine is a 2010 MB, white, now with 16GB of Ram and a 500GB SSD, it's running that OS that we are all waiting for
It came with Snow Leopard (10.6.4) and lived in its box from new until last October (a gift never given) turned out to be quite a machine
My daily driver is an 09 MBP which fits well so I use it in preference to any of the newer machines I have (and that is a lot) but they all have jobs already.

If it shipped with 10.6.3, and you upgraded the firmware to allow Internet Recovery, then it has some weird behavior which I don’t fully understand.
I’ve heard that you can no longer boot from the original install DVD. However, I don’t know what gets installed during Internet Recovery. It didn’t ship with Lion, but that would be the logical choice. It may just install what is on the Recovery partition. I don’t know what it will do if your put in a blank hard drive.
I realize that probably created more confusion, but if you have the ability to answer some of those questions, it might be interesting trivia, and helpful to some others in your same situation.

Oct 19, 2014 2:06 PM in response to Loner Tby Justice7,LonerT,
thanks for the reply. Interestingly enough, i never had Yosemite installed. I had erased my drive to do a clean reinstall of Mavericks OS which is what i had installed, since this was a few days before Yosemite release. When I went to do internet recovery, it tried to install Yosemite....
Finally, i ended up doing a reinstall off my time capsule from about a year ago (just how far i chose to go back because i had a smaller backup back then).
This actually put me back to Mountain Lion. Once reinstalled, i erased the drive again. Also, i partitioned the drive to 2 partitions, the smallest partition being around 36 GB(couldn't get it smaller than that). I did internet recovery again and this time it again installed Yosemite. Yosemite actually installed correctly this time without the error "temporarily unavailable". Drive is clean and Yosemite installed and working great.
This was my initial goal to begin with. But, if anyone has the same issue, this method worked for me.
** I did NOT have a USB or other external drive to use for the "preferred method".
