don't you think i't would be great a pinned post with all the known issues of every os release and update, it could save us a lot of time!!
Perhaps, but it takes a lot of time and effort to maintain it
Every version of OS X brings tons of errors for the x86 scene. To pin the known issues, we would have 14 pages of pinned topics, people needing different information, need to go through it.
We prefer encourage to learn and to understand. We have the search feature who's a pretty good tool. For most problems, there is an answer, and if not, you can open a topic for your problem.
