If anyone's thinking of tinkering with iOS 7, think twice as Apple warns you can NOT roll back to iOS 6. It probably has something to do with the new kill switch technology built into iOS7. Allowing a roll-back to iOS6 might provide a thief a back door to get the device in a sellable state.

I've read from (apparently ex-)beta users who were able to return to iOS 6. That backdoor you're describing won't work anyway. As soon as iOS 7 goes public, Apple will stop signing iOS 6 restore requests. As long as iOS 6 is still the latest public version of iOS, restore requests to that FW are being signed, which means you can go back to it any time you like. You might have to enter DFU or something, but it should be possible nonetheless.

It's what I hate about an OS never meant for anyone but software developers; the amount of chatter by impatient toadies who torrented it, buggered their devices and complain about it in the forums.

But if it's out in the open like this, it means someone who should have known better leaked it.

Or not, I guess all you have to do is pay $99, so you just need to have $99 in disposable income and a desire to leak it for whatever reason.

Alright - I did it.

I installed the DP of Mavericks on my system and now I can't downgrade. It's so incompatible right now and my machine is running slower.

How can I go about downgrading this?

I have Mountain Lion in the Mac App Store as well is Disk Images of Mountain Lion.

Really appreciate any help!

Question 1: Do you have a bootable installation USB drive of the Mountain Lion? If the answer to this is "yes", then restart your computer, press alt to bring up the boot menu and boot into ML's installation system on your pen. From there, bring up the disk util and wipe your entire hard drive, then go back to initial installer menu, and install ML on your HDD.

If you don't have a ML installation USB, you'll need to create one under Mavericks. You find how to do that in google (just google "creating mountain lion USB recovery).
The important thing is that you DON'T TRY TO DO ANYTHING FROM 10.9'S RECOVERY PARTITION as it will detect that whatever you're trying to install is older and it won't allow you to do it.

PM me if you need more advice.

P.S. to other OP's. If you're so bothered with people making mistakes and don't want to help them, then don't. But please refrain from being sarcastic and shoving in their faces how stupid they are and how you hold the key to the secrets of the universe. If you need to humiliate people in these forums to ascertain your skills, you're a very sad person and I feel very sorry for you. It must be difficult being stuck on a mental age of 9.

Thanks for the help! What I ended up doing just before you posted was I created a new partition, installed ML with no issue, then I am going to delete the old partition and make the new partition my main one. Do you see any issue with that and would you recommend your method of a total wipe and installing off a USB instead?

That should do it too. My thing with partitions is that I generally dislike doing them, so I avoid it whenever possible. I much prefer having a solid Time Machine backup, wipe everything and then have my computer up and running where I've left it. Especially since OS X introduced recovery partitions I started disliking them even more, especially when you have 2 copies of OSX installed and a recovery partition for each. It's my Virgo nature. I like things simple and organised.

I may just do that. I usually don't partition but I didn't think of your alternative so I didn't see any other way. I haven't really done anything on my system yet so I might just wipe it again lol. Thanks!

I have 2 questions from this thread:
1. If you restore from the Bootable installation file, does it keep your files from Mavericks?
2. If you do a internet restore (command option r when boot) , does it keep your files from Mavericks?

Regardless of the source its purpose is to provide a hardware platform for software development. It's not designed for the end user and many features are still in testing, missing or broken.

Maybe it would be to your benefit if you were a real developer rather than tormenting and living to tell us about it here.

You seem to have missed the point of my post so I'll create a separate thread. As for my not being a developer, when did I say that?

Internet Restore 2013 MacBook Air

I have found the answer, if you are using a June 2013 MacBook Air.

Today after installing the DP4, I noticed a large chunk of drive space missing (89gb free down to 50gb free). So I started nosing around and eventually found over 222k .tmp files holding almost 50gb of data in /var I didn't know what it was, but when I opened the tmp folder Finder would get really sluggish. Attempting to delete these files proved to be damn near impossible so decided I wanted to reload ML.

Anyways, I have been searching too for a way to downgrade and I accidentally found a way.

Prerequisites:

Power: Plug your ish in
WiFi: Make sure you are connected to a decent wireless network before starting

Step 1: Reboot into Recovery mode (cmd + R at boot)

Step 2: Open Disk Utility

Step 3: Select your SSD NOT the partition the OS is installed on

Step 4: Select the Partition function (its over to the right)

Step 5: Under "Volume Scheme" click on the menu where it says "Current"

Step 6: Select "1 Partition" and then hit Apply

Step 7: Exit Disk Utility

Step 8: Reboot your computer

Step 9: When the computer boots the screen will stay grey for a while and then a small white folder with a question mark on it will appear and begin to blink. (the moment I almost ***** myself)

Step 10: Hold down the power button until the machine shuts off

Step 11: Boot into recovery (command + r) and relax as Apple's servers automatically push a restore image onto your MacBook

Step 12: At some point your MacBook will reboot back into Resore Mode and that's where you will be given the option to Reinstall OS X ML

Solution! I did this myself.

Here is the link to the YouTube video i created that shows you step by step how to go from OS X Mavericks 10.9 to OS X Mountain Lion 10.8. This tutorial took me a long time to figure out so your support will be appreciated! Also, this does not use time machine. All you need is a 8gb usb. THANKS!
