is a way to get rid of incompetible or CCs ?

Welcome to the game and to these forums!  I love meeting new players.

I don't have a MAC, and I don't use a lot of CC, but most players who do use the 50/50 method when they have issues after a patch.  

First, save a copy of your current game's save file to your desktop.  JUST IN CASE.  (You'll see why.)

Then, put half of what's in your /Sims4/Mods folders on your Desktop (somewhere the game can't see them).  The only file that HAS to stay in /Mods is your Resource.cfg file.  Don't move that anywhere.

With half the files in place, start your game.

If everything works, your problem files (could be either mods or cc, it pays to check EVERYTHING after an EA patch) are in the other half.  

If you have problems with THIS half, the trick is to exit without saving (but the COPY is for in case you forget, because saving in this state will trash what cc on sims is NOT in /Mods for now).  Then, you'll need to cut that batch of files in half again, and keep drilling down after each test, until you find the offending file(s).

Some people do it by taking everything out and putting things back together one folder at a time, and testing between.  It just depends on how much you have to go through, and how you have it organized.  Either way is a good process.

When you figure out what isn't working, go back to its site and see if there's an update for it.  That's something we all end up doing after each patch, updating our mods and cc for new goodies from EA.  And if you'd let us know what you find out, that would be wonderful.

It's a little bit time-consuming, post-patch mod/cc maintenance, but the payoff is a working (prettier!) game.  So, I'd say it's worth it.

Hope this helps!
