RoaringApps.com is reporting problems with running TS3 in the new OS which is due for release imminently. Apparently a 3rd party program is needed in order for it to run smoothly. Don’t expect a patch from EA over this anytime soon, or ever.
I’ll be updating to Lion as soon as it comes out so I’ll keep you all informed. Sod The Sims 3, I’m not sacrificing a great new operating system for a game 😉
