[Game Downloaded from Apple Store, Serial Code for Steam Activation?]

I downloaded the game from the Ap Store, where can I find the serial code to sync with Steam or did I have to download it through them? Using Mac OSX Yosemite.

[Sudden lag in middle of play through?]

Hello everyone,

 

So in the middle of my second play-through (thief on PoD) my game suddenly hits a huge amount of lag and runs choppy from there on out. No amount of reloading other saves or the game helps, but waiting a few days seems to. Except it ran smoothly for about 20 minutes before returning to THE SUCK. From what I've seen online it's either blamed on the system or the 3D characters, but these don't make sense to me because I ran a entire play-through without a single graphics incident. Is it just a matter of waiting for a patch, or can I do anything?

 

Specs:

 

Running the game on low graphics

Mac OS X Yosemite 

2.66 GHz Intel Core i7

4 GB 1067 MHz DDR3

NVIDIA GeForce GT 330M 512 MB

 

Thanks guys and gals,

Kyle
