Aug 7, 2015 10:30 AM in response to agasssby morleybrown,i'm trying to go from yosemite back to mountain lion on my macbook air
there was no "mfgr.'s ID and size" just an icon of a drive called Mountain lion and underneath the line 'disk 1' and underneath that OS X Base System.
I tried Disk 1, and Partition, but there is no "Volume Scheme heading"
Pictures would go a long way here : )
Thanks,

Don't see any discernible benefit to yosemite.
It has made the whole MAC experience poor.

Aug 10, 2015 12:35 PM in response to Kappyby julieta maria,Hi Kappy,
Quick question about downgrading from Yosemite to Mountain Lion:
I've read your instructions and it's all clear to me. Just wanted to confirm that it's not possible to downgrade WITHOUT having to erase the disk.
If erasing the disk is the only option, do you know if Time Machine will let me import Applications & Files only?
It's my brother's computer I'm checking about and I'm not sure which OS X version is in his latest time machine back up.
Thank you very much!
Julieta

Aug 10, 2015 12:52 PM in response to julieta mariaby Allan Eckert,That is correct that the disk drive must be erase before you can install an older version of OS X. The reason for this is the installer will fail if it detects a newer version of OS X.

Aug 17, 2015 4:46 PM in response to astrachby MacOwner40,I have a MacBook Pro (Mid-2012) running Yosemite currently. I want to downgrade to Mountain Lion, since that's what came preinstalled on the mac, but when I tried the Internet Recovery option, it said I couldn't complete the operation because I had a newer version installed. Any way around this? My time machine backups from mountain lion/mavericks were deleted... any ideas?

You would need to erase the drive and use an earlier full installer.
But why would you ever want to. 10.10.5 contains numerous security fixes and hundreds of bug fixes. AFAIK, there are no apps which were OK earlier that were broken by 10.10.5.
