I want to go from 10.8.3 to 10.6. How do I do this?

I erased the HD in Disk Utility (tried to erase the one with all the numbers but got the message "unable to unmount") and then used a disk to intall 10.6 but this didn't work, forgot the message I got but it wasn't allowed. My goal is to go to 10.7 wich I purchased in the Appel store. Does anyone know how to do this?

iMac, OS X Mountain Lion (10.8.3)

No, it's from 2011.

You need to determine which version of Lion was installed on the iMac at the time of purchase.

Thanks. My computer was shipped with 10.6.2. So I guess that explaines why the 10.6 disk didn't work.

I understand your confusion. Since I have a 10.6 disk I wanted to use that and from there upgrade tot 10.7 (which is my goal). 10.7 is still in the App store but I don't know how to download it again. I erased my HD and when I want to reinstall I never get the option to go to the App store and download 10.7.

So I ended up downloading 10.8.3 again (my only option). Mail problem is fixed but now my pc won't go to sleep anymore.

I'm still motivated to go back to 10.7 and still need help -)

If it the Mac was from 2011, and if it had Snow Leopard, it would have come with 10.6.7 and you can't use the Retail DVD, which is 10.6.3. You would have to call Apple and ask for replacement discs.


And if you are trying to use the DVD that came with another Mac, that might be why it's not installing.

I have no idea why you want to revert to Lion, and this is getting very confusing since the information you keep giving is very unclear. I'm tempted not to post anything more, but I'll give this one more shot. This would be to get back to 10.8, which you appear to have been running before you erased the drive.

Getting back to Lion from Mountain Lion is either impossible or extremely complicated. I don't have an answer for that one.


But you can get to Lion from Snow. If your Mac is from 2009, then the 10.6.3 retail disc or the disc that came with the computer should install. And then, maybe, you can find the Lion you originally purchased registered to your Apple ID at the Mac App Store. But you should know that if you go this route, you will lose all your user data, since the drive will need to be completely erased before installing Snow. You should make a backup on an external drive before doing this, that is if you haven't already lost all your user data.


That's all I know. Perhaps if you bring your Mac in to an Apple Store they will help you out there.

Thanks for you help so far and I'm sorry if I'm being unclear. Recap:


I was running on 10.8.3 and got all kind of problems, therefor I want to go back to Lion. Lion I purchased in the app store and I don't know how to run it since the install window (DU) (after erasing my HD) doesn't allow me to download Lion from the app store. So now I'm back on 10.8.3 again, this time with different problems than I had.

I either didn't use the original disk to reistall or the system is really working bad. My pc is from late 2009 (not 2011 as I posted earlier).

I can't go to an Apple store because I live on Bonaire (Dutch Caribbean), even getting an appointment with a genius is hard since my phonenumber is not accepted.


Hope this clarifies a bit.


Thanks again.

You will see from reading this rather long thread that downgrading back to Lion if you didn't make a backup before the upgrade is either impossible or very difficult.


https://discussions.apple.com/thread/4177831?start=0&tstart=0


I've already given you a link to instructions for downgrading back to Snow Leopard, but maybe it would be best for you to try to address the problems with Mountain Lion, since that might prove to be the least difficult approach to this.


I think you should post a new topic directly in the Mountain Lion forum. You should give full details of your Mac, including how much RAM you have installed and the problems you have been experiencing. Do not include your serial #. If you can get ML to work properly, it may be a superior OS to Lion.
