So I downloaded the installer that was available as a code in the iOS 8 beta 4 developer center. (which took 25 mins for 5gb when running Mavericks) It downloaded the installer and game me the release notes of the dev preview 4. I installed the beta on a separate partition but it seemed to install the 1st developer preview. I then went to the app store and found an update.... then another one when I woke up the next day and another one (All called OS X Developer Preview Update 1). Finally it said developer preview 2 and installed that after a few hours. Now I'm trying to install developer preview 3 and it's giving me an estimate of 7 hours to download just 1 gigabyte of data! Is there any away to download the 4th developer preview without having to waste my time with the ridiculously slow downloads?
