[MAC] Sims 3 Toddler won't grow up using cake or cheats.

Stuff like that is usually due to some kind of corruption.

Could be clothing or something else.

Try the following tips

• Reset the toddler with resetsim firstname lastname
• Move the toddler (with a parent) out and back in
• Change their clothing beforehand.

I don't know how to reset the toddler... Is it a cheat? 

I can't change the clothes of the toddler either, it just keeps loading.

I moved the toddler and Dad out of the house, but that's when I remembered another thing, on the family picture thing, when you click on your household, the toddler doesn't show up, the other family members are there, but not her.

Any other suggestions? Thanks.

Yes, it's a cheat.

open the cheat console with ctl-shift-c, then type the cheat as mentioned above.

If your CAS doesn't load, you might have bad cc though.

Try resttetting your user files as described in the factory reset described in this post: http://answers.ea.com/t5/The-Sims-3/FAQ-Troubleshooting-Steps/td-p/714/

You won't loose anything. Just make sure to not delete any files  and make a backup.

Gotcha, so I type the whole thing in for the cheat?

Hello, yesterday I was trying to solve this same problem and this is what worked for me:

I had tried EVERYTHING suggested by every possible post I could find. All the cheats for aging and even the ones for resetting. I had tried the cake many many times and editing the town, moving my family out using the phone or the town editor. Evicting the family and even edit the sim itself (a toddler who was also a girl werewolf). Some solutions did nothing, some others made my game freeze.

Finally, I did the resetting of the game as it IS mentioned above, but that gave me much more problems than what it solved, so I put the files back (even the custom content). My main problem for this was, perhaps, that my game was in Drago Valley (and this is an extension that is connected to the CC). So, while I was copying my content back I noticed 2 folders for my saved games (saves folder). The first one had the Bridgeport.sims3 (I think this depends on the kind of city you save your game) and the other was bridgeport.sims3. backup. I checked those folders before copying them back and I noticed they had very similar files with different last saving dates. They seem to be in pairs staring with the name of the city you've ever played. So you have a couple of files starting with the name Frace, for instance, if your Sims have ever been to France and I noticed there were a couple of files starting with the name Dragon Valley but with a previous date as the last modification. I immediately assumed this was my previously saved game and I thought accessing the game through this previously saved position, would give me a chance to prevent what had gone wrong. So I replaced the 2 files in the bridgeport.sims3 folder and I opened the game.

I was quite happy to discover that, by doing this, I not only was back in a previus saving point as I had thought, but I also was able to see my toddler in the pictures again and I could see her face when selecting her to do an action. I was able, even, to edit her using the mirror (all these actions were troublesome before). So I played for a while and I bought her a cake and I had the same problem again. I signed out without saving and I tried many things so, this is what really worked:

*I removed the custom content in my baby (it was just hair) using the mirror.
*I made sure she knew how to talk, walk and was potty trined (just in case)
*I used the cheat to age her instead

And voila! I have a lovely girl now! I edited her in the mirror just to see what hapenned if I gave her custom content (I used a different hair this time) and I discovered, her hair changed from custom to a regular kind of hair for no apparent reason. So I think there's something strange with her so from now on I won't use CC on her.

I hope this helps somebody with this same problem, since I think maybe you gave up or solved it in a different way (so share if you did, please!).

Hello! I have a mac too, and I am having the same problem! It was my twin toddler's birthday, so I bought two cakes and set them on the dining room table. I aged up Abigail using the cake and was moving on to Alaska but that's when it happened. I clicked on the cake with the mom, selected "Blow Out Candles" and  selected Alaska to age up. She blew out the candles- nothing. I tried again. Nothing. At this point I made the dad drive to the grocer's and buy a new cake. I blew out the cake again- didn't work! I tried to use the "Trigger Age Transition" cheat, but to no avail. I reset her twice.. Still didn't work! She is using cc, and we live in a Sims Resource house in Sunset Valley. But after I did Trigger Age Transition for the last time and clicked on the doors to the room she was in to lock them, something crazy happened. My headphones repeated something in a robotic voice that sounded like 'Setting'.. What? The game then said to debug something and I clicked debug. Um.. help?

When I had twins on the sims 3, one aged up a few days after her twin. Hope it helps!!

I was looking for a fix to think myself. I found a similar solution. If you happen to already have the nrass master controller mod installed you can just click on the sim and then select nrass, then master controller, advanced, and finally reset sim. I had already tried resetSim [firstname] [lastname] and it didn't seem to solve anything. After I reset my toddler sim with master controller I was able to customise her with a mirror and age her up. If you don't have nrass master controller i highly recommend it. It doesn't have any viruses and it cant be VERY helpful!
