The upcoming version of "OS X", which is macOS 10.12 Sierra, changes the canonical name of the operating system series from "OS X" to "macOS".

Therefore, I suggest that either to move the tag to and leave a synonym for , or make be the synonym of .

Here's a related discussion on Ask Different Meta:

    Given all tag names are lower-cased, if we go ahead with this I would recommend [mac-os] over [macos] for readability.

  • @fredley Uhh, never mind the deleted comment if you got a notification, but a quick look on Ask Different (apple.stackexchange.com) revealed that they have different tag conventions, (e. g. [osx] while ours is [os-x]), so we could go ahead with [mac-os] even if other sites use [macos]. Jun 29 '16 at 8:08

    Can't this wait for Sierra to go golden?

Done. I've mapped and to . Since Sierra isn't even out yet it doesn't make much sense to switch away from until then, provided we do that at all. Despite the name change I suspect most folks are going to call it OS X anyways, so we'll probably just want to stick with that even after fall rolls around.
