When I see the PC equivalent to that error, my machine has either run out of resources or my OS is unhappy. This goes for any game not just Sims.
What to do about it is where I run out of suggestions. It's been too many years since I worked on a mac to be of any real help.
So I'll throw out what I'd do if it where my PC and maybe you or some Mac expert will know what the Mac equivalent is.
I'd start by cleaning up the hard drive. Getting rid of temporary internet files, etc. Next I'd defragment the hard drive.
If it was still happening, I'd run a scan disk to make sure that I didn't have any bad sectors on the hard drive.
If I was still having issues, I'd haul my PC off to a tech and have him check to make sure all the RAM was functioning properly, reformat the hard drive and re-install the OS and updated all the drivers.
