ok, just a quick run down of what i did...(im deploying to iSO) not sure if its different exporting to mac store over iOS? would assume its the same
1. Create a cert on apple mac, upload it to apple to get my dev and distribution certs..
2. Download both dev and distribution files and run them on my mac.
3. export the distribution one and set a password.
4. then create a provision profile for my app (distribution)
5. Create a provision profile (dev + UAD device) dev not adhoc
setup the ios details in stencyl to be the exported file in step 3 + added the password
set the distribution file to the file in step 4.
set the adhoc to file in step 5.
I hope that helps
also, i needed to open xcode, and goto preferences, select my apple id and download the provisioning profiles that i had made in steps 4 and 5
