Mac Patch? Unable to update & install Pets.

I'm at the stage where I have the .dmg file of Pets and ready to install, only problem is when I am half way through the installation it fails as I haven't updated my game (base game), I need the 1.2.7 patch for Mac, any help?

Did you keep any of the original files before patching them?
I always recommend that you keep a copy of the original files and not just replace them with the cracks.

This topic is a few weeks old so I have no idea if you solved your problem or not but anyway:

I don't think the 1.2.7 patch for Mac is available anymore. I was looking for it at some point as well. Try installing Town Life Stuff or Generations, I think it updates the game through installation. Then download the latest patch (1.27.5 I think). And try installing Pets again.
