Buy the game Monochroma some time ago and no one achievement has earned until I passed it. Already trying to get help in steam forum, but nothing. Maybe anyone have this kind of problem on mac platform with steam games? Thanks for watching!

    How is that a Mac problem?, what Mac do you have? – Ruskes Dec 18 '14 at 18:30
  • Yeah, only in my MBP latest 2013. – k1r8r0wn Dec 19 '14 at 4:03
  • Any more variants? – k1r8r0wn Apr 4 '15 at 12:59

Steam uses OS X's Accessibility API for the Steam Overlay (Shift+Tab screen) and to communicate between the game and Steam.app. You probably enabled it when you installed Steam. Unfortunately, every time you update Steam (this is a bug in OS X) you must uncheck and re-check the box in System Preferences. If you're having this issue on your Mac but not Windows, that's the reason.

Just go to System Preferences > Security & Privacy > Privacy > Accessibility, unlock using the icon in the bottom left, and uncheck and re-check Steam.

  • Thanks, but not helping for me. Trying it for many times - but no changes. – k1r8r0wn Dec 19 '14 at 4:22

I'd try:

  1. Make sure all your OSX updates are installed
  2. Follow 0942v8653's suggestion and toggle off the Accessibility API for steam
  3. Completely remove Steam
  4. Reboot
  5. Reinstall Steam
  6. Toggle back on the Accessibility API
  7. Reboot

There may well be better ways, but this is my hip-shot guess on this one.

  • Unfortunately, not help too. I think it's a game issue. – k1r8r0wn Dec 23 '14 at 7:04

You need to give Steam access in the accessibility settings and then you may need to restart Steam and or reinstall. I have had a similar issue where Steam does not detect that it has been given permission in the settings and it was fixed by a quick reinstallation of Steam.

  • Already try this kind of variant - not help. Anyway, thanks for the answer! – k1r8r0wn Dec 28 '14 at 11:51
  • Weird! Whenever I have had this issue that has worked. Wait, that was on Mavericks! Let me try now! – user106403 Dec 28 '14 at 11:53
  • Now, I am experiencing a similar issue. – user106403 Dec 28 '14 at 12:00
  • As i said above, I think it's all about this game - "Monochroma", other games achievements work fine. – k1r8r0wn Dec 28 '14 at 12:02
  • Weird, I experienced it on other games to. – user106403 Dec 28 '14 at 12:04
