In How to open time machine progress bar window I asked a question regarding the version of OS X I had installed at that time, namely Lion. I got an answer matching that version, indicating that what I wanted was not possible. I accepted that answer, ticking the check mark.
Recently (or perhaps not that recently) there have been some answers indicating that what I wanted is possible these days. But I'm pretty confident that all those recent reports are for a newer version of OS X. And since I'm not running Lion myself any more, I cannot verify whether those answers do in fact apply to Lion.
So my question is this: should I change the accepted answer in order to keep the page up to date? If I do, should I remove the version tag as well? Or is it enough that the other answers are there (a bit down the page) for those who search, and leave tag and check mark where they are as an indication of the history of this question and its answers? I tend to do the latter, but the more new answers come in, the more I doubt whether ignoring them because they ignore the version tag is really the right choice.
