I am also having the same problem with the gallery crashing 100% of the time I have tried all the above suggestions. I have a macbook air. Please help!! I have also noticed that I do not have a file/ thread that says EAWebKit.so (I have searched for hours).
Recently, whenever I click on the gallery it doesn't open and the game crashes, instantly taking me out of the game. I've seen other older threads about it but nothing has resolved my issue. Is there anybody who is able to help?
That is the Sims 4 folder, not the app. You're not looking in the right location, please follow the instructions to find the file then repair your game.
