i doubt it...it's a very small patch.
this is what it says on the steam update log:
For the recent Mac OS update 10.9.5, we have released a hotfix that solves signature issues.
We seized this opportunity to also fix the combat log disappearing for some of you, and fix jumping journal entries.
If you load a savegame in which the combat log was gone, you may have to drag it above the skillbar to be able to resize it again.
On the Mac version, the GodRays effect was distorted and this was fixed as well.
Have a good weekend!
