Actually, though, Safari won't let me access the Developer's website. So how do I download it manually? Safari has been messed up ever since I got DB1.There are direct links in apple's developer forum. You can download them in a browser and install DP2 manually thereby circumventing the mac app store altogether.
You have to be a registered developer to access them (which you should be anyway since so far el capitan has only officially been released to registered developers).
We can't post the links here on macrumors though because that breaches macrumors rules.
I don't have any other browser downloaded on my Mac and it won't let me download any others, because of the same error that constantly shows up. I'm lost.You could try another browser (or even a different operating system).
I actually find that they download quickest via google chrome in windows 7!
Sounds like something is going on with your SSL, I have no issues with the developer.apple.com link though the computer I'm on currently is running Mavericks.it sounds like something is broken on your Mac preventing SSL connections to work. try getting Firefox or Chrome and seeing if you can download it.
I installed it for a quick second because I got malware on my Mac from streaming a third-party movie and forgot to take it off afterwards. It won't be back on though!you should never install that stuff, especially on a dev release system (but in general don't bother with antivirus on OSX, it will cause more trouble).
