@e93to Have you submitted a support request/ticket to Feral Interactive for this issue? They are really good about responding to such reports.
I think the game doesn't work because my iMac is old... It requires at least 1gb vram (2gb recommended). My iMac has 512mb or so..
Sometimes system requirements are more of a suggestion. I have an iMac of the same vintage as you, and I can run the Metro Redux games. Now, that's at about 10-15 fps, but they're playable.
I don't know if Alien Isolation has similar flexibility or not.
If you get killed you start over? Or can you revert to a previous save?I first played it on novice difficulty. The atmosphere was great but I found the game too long and repetitive. Restarting after being killed gets annoying.
To enjoy the atmosphere without being bothered by the alien, I replayed it with a mod that makes the alien ignore you.
Of course you don't start all over, since the alien kills you in one hit. But the last save (at a checkpoint) can be be a long time ago. You may also die a lot in difficult areas.If you get killed you start over? Or can you revert to a previous save?
