Game freezing up
I just bought the Mac version of the game through Steam, and the game went fairly smoothly for the first 300 turns or so, but lately I can barely play for 10 minutes before the game just freezes up and I have to hold the power button on my computer to turn it off. The game doesn't freeze up at any particular place in the game.
My system specs (the better version of the new 2011 Macbook Pro 13")
2.8 GHz Intel Core i7
Memory: 4 GB 1333 MHz DDR3
OS: Mac Lion 10.7.2
Graphics: Intel HD Graphics 3000 384 MB
I am playing on a standard sized map with graphics settings set as low as I can put them. I'm aware that this isn't exactly a gaming computer, but I more than meet the minimum requirements for the game and there is no reason that this should be happening.
I am considering asking for a refund from Steam if this issue cannot be resolved.
Support for the mac version is provided at www.aspyr.com
Have you verified that your Intel graphics are fully compatible with the game? Integrated Intel graphics and shared video memory have both been shown to be an issue and may not be supported. You might be able to play a minimum game but could crash when the game gets more complex. Lots of prior posts on this subject.
So not a Steam or 2k issue, its likely your laptop.
Try playing in Strategic Mode which uses far less graphics and also has no flashing lights which could disturb some folks over time. That's the only mode I use it with Resource colors displayed to easily locate Luxury and other resources.
To be clear, you meet the minimum requirements and do no better. Your video chipset, while officially supported by Aspyr, is not impressive. You should seek support from Aspyr, using the link QuantumTarantino provided.
It's worth noting however, that with both MacOS and Vista/7, a non-responsive computer hints at hardware failure. Perhaps that is caused by game stress, perhaps it is some other issue. Either way, it is not the sort of behavior that a game can initiate on its own. You should ensure that your CPU is not overheating and that your overall system temperature hasn't risen too far. Macs are normally pretty good about this, but I don't have enough experience (anymore) to say how the 2011 systems are set up.
