I think I might have a solution to this problem. I used to have the Sims 3 Seasons crash all the time, even after the 1.47 update. But reading the crash logs showed "Access Violation", which I think meant that it ran out of allocated RAM and used some of the remaining RAM that it was not allowed to use, forcing Windows to terminate the program.
Anyway, the solution is to allocate more RAM to the Sims 3, which is easiest done with RUN AS ADMINISTRATOR!!! If you run the Sims program as an administrator you automatically have access to all of the RAM. This is a solution to Windows (I have Windows 8). I'm not sure how Macs work. And I'm not sure that this is guaranteed to work for everyone as I haven't tested anyone else, but after doing this I haven't crashed once.
To run as Administrator right click on the icon to open Sims 3 and choose Run As Administrator. To keep the setting and have it run as administrator automatically every time the SIms is opened, right click the icon and go to Properties. Go to the Compatibility tab and at Privilege level tick the box that says Run this program as an administrator.
If the 1.47 update hasn't fixed your game crashing, I hope this helps. I know this problem is very annoying and can make the game practically unplayable.
