Since I installed XCode 4.6, it keeps on downloading the Doc Set each and every time I open it. I've seen a lot of threads talking about this topic, so I tried to manually install the doc set in the Developper/Shared/Documenation/Docsets folder. But even with that, I opened XCode this morning and.... it started downloading the thing again. What can I do to make it stop ?
Click the link under Xcode->Preferences Click on Xcode 4.6 doc set you will see an installed location. click on that link and delete the file. In my case there was another Xcode 4.6 file I think it was called Xcode 4.6 Documentation set I deleted that as well.
I closed XCode and opened up again the told it to download it again and it took.
You should only have one Xcode 4.6 file in your list I had two and I don't know why. Might be something left over from the 4.6 beta.
Hope it help
