There is a glitch that makes the Mac OS X menubar appear whenever I move the (hidden) mouse cursor over it. When the menubar appears the game lags heavily and if i'm pushing a movement key (w, a, s or d) when this happens the key will "stick" until pressed again.

Typical scenario:
I'm playing the game and want to look "north" while walking in that direction so I move my mouse upwards, the Mac OS X menubar appears everything lags for a short while and my dude is now walking north without me pushing anything. Of course the basic reflex is to counter the movement by literally pressing everything but "w" (the direction he's already walking in) to make him stop walking. Usually it is too late to stop him from walking unless i'm lucky and he's just hitting a wall instead of running into a dog or a shotgun barrel.

Also when playing on a multiple monitor setup the mouse is not exclusive to the game so if i have a website open on the other monitor I will be accidentally clicking and right-clicking that website during gameplay. Even worse if I just have the desktop visible on the other monitor. Then my right-clicking will be having the system compressing random stuff to a zip archive and attempting to burn stuff to CDs and DVDs.

I hope this will be fixed someday. Going to attempt playing using a controller or keyboard only until then.

I noticed this too, but if you play it in original mode (not updated) it fixes this issue.

Yep, this happens to me too. Pretty miffed about the general quality of the Mac version. Crashes and bugs out the wazoo.

I've been playing on the MacBook Pro and apart from the achievement crash that has now been fixed, I've had no other issues. What version of OS X are you running? Yosemite?

Yosemite 10.10.2. I'm also crashing at the end of level 11 Dead Ahead. So I can't progress at this point. I've also noticed frame rate issues since the last update.

Strange... I'm running same OS X and game versions as you and no further issues. Wonder if it has something to do with hardware...
