Re: Sims 3 Problem connecting to Server on Mac

@alazee1113  That's a message we haven't seen in 2019, although it was a huge problem last year.  From the screenshot, it looks like you were online when you launched the game?  If so, this may well be the same issue as before.  There are a couple of fixes, but the most straightforward one for you may be to just go ahead and install both your packs.  Last year, adding Late Night was enough to get around this message.

You'll need to apply one small fix for LN, otherwise you'll get an unknown error message.  Just create an alias (icon) for LN in Applications\The Sims 3, alongside the alias for the base game.  This is simple:

If this doesn't work, let me know, and I'll do a test install tonight to see if I can figure out what's going on.
