Hi There! I have a little question, i am trying DP3 right now and want to upgrade to DP4. I Downloaded the DP4 img from the Developer portal but i don't get the second installer to start. First the installers fixes some files and then it needs to restart, after a restart the installer hase to install DP4 but at my MBP it just come's back in DP3. (i am on a Late 2011 MBP 15" so i sould be fine) Is there anyone with the same issue? Or is there maybe someone with a solution? Please let me know.
