Sims 3 64-bit "quit unexpectedly' Mac

@jadasimsxox  The issue here may unfortunately be the Pets expansion.  Sometimes it's enough to play without any pets the active household, and sometimes the entire pack needs to be removed.  But it's obvious from the many reports that the content doesn't work well on Macs with your category of hardware.

If you'd like to try intermediate steps, e.g. removing pets from your save and using mods to prevent them from spawning, let me know.  Otherwise, your only move may be to uninstall Pets, which you can do by simply deleting the EP05 folder from the Sims 3 Packs folder, which will be in either Applications or Users > your username > Applications.

@jadasimsxox  Playing a save without all its expansions usually doesn't work, as in, the save will crash, fail to load, or maybe just run very poorly.  So if you can't play with Pets installed, you'll need to start a new save.

If you really want to try to recover this save, there are mod-related ways to move out the dog or even remove all animals from the world.  But it kind of defeats the purpose of playing with the expansion at all.  Let me know what you'd like to do.

@jadasimsxox  NRaas MasterController can remove any sim, including pets, from the world; the command is called "Total Annihilation" and can be applied to any subset of sims you want.  NRaas Register controls the stray population and can set it to zero for each type of stray or wild animal.  NRaas Overwatch can shut down the neighborhood pet adoption scenario, which may also be a problem.

So this is more a piecemeal attempt to control things rather than one sweeping fix.  I don't even know if it's possible to completely prevent the crashing due to animals that many players are seeing, other than uninstalling Pets entirely.  But those are the mods you'd use to try.  If you want help adjusting their settings, feel free to ask here or on the NRaas site.

Hi! im having this issue too☹️ I also have the Pets expansion pack, but is there any way, I can play the game without the need to uninstall the Pets expansion pack. I really love that pack and it's basically the center of my gameplay. I don't know if it would be possible, but I just have to ask🙂

@Sarah_Ulmer  I honestly don't know whether it's possible for people getting this kind of crashing to play with the Pets EP.  So far, I haven't been able to come up with any suggestions that helped, and it's pretty clear in a lot of cases that the presence of one or more pets is the problem, in that removing them is an immediate fix.  A few people have reported that they can't move in a household that already includes a pet but can adopt one later without issues.  It seems to be hit or miss.

If you're willing to use mods and to experiment a bit, you could install NRaas Register, along with MasterController (for its useful commands), and ErrorTrap and Overwatch (for maintenance and error cleanup).  Start a new save, use Register to set all the stray pet pools to zero, use Overwatch to shut down the neighborhood pet adoption scenario, and use MasterController to remove ("Total Annihilation") the existing animals in town.  Unfortunately, the only way to stop inactives from adopting pets entirely is with StoryProgression, which is a heavy mod, both in terms of impact on performance and in terms of its effect on the game.  But you could set it to the slowest pace and shut down most forms of progression for inactives to limit the extra resources it needs.

I don't know for sure that this will help, and it does take a little work to set up, so I'd understand if you don't want to try.  But if you do, and you need more specific guidance, let me know.

It's also still possible that EA will identify the issue and patch it at some point, although I have no idea how likely that is.  And of course if you get a different computer in the future, the pack will still be available to download from your Origin game library.
