I just installed ML/Xcode 4.5 and iOS 6. I did this on a new drive so nothing was carried over. I have my old stuff on a SuperDuper! backup. I've got everything working so far, but I'm stuck on the code signing/ cert stuff. It was so long ago, I've forgotten the process and I'm pretty sure it's all screwed up now because of several tries. Q. How do I certify the computer? I see Xcode-Organizer-Devices-My Mac - Developer Mode ... the provisioning profiles under this is empty. Q. I assume I was supposed to do this BEFORE I did a provisioning for the device, how can I reverse this? Maybe delete all profiles on the device and on the Apple developer site? Q. Is there a link to a step by step showing how to do this including using keychain access. The ones on YouTube suck, they are old and I don't see the same choices. I really need a click by click directions here, but can't find a good up to date site. Thanks.
