Error [135dec40:90f690cf:00000075:495f32a0] (HELP!!)

@lehoeven Try this:

Change the language to something other than English
Do a "repair game"
See if it launches with the foreign language

@dzm06 I actually got my game to run again, but thank you for your reply!

@lehoeven Fantastic! Glad to hear it. Would you mind summarizing what steps eventually worked for you?

@dzm06 In the end I decided to disable SIP. I know it is a risk and I enable it again once I’m done playing. I wouldn’t necessarily recommend it because it makes your Mac no longer secure, but it worked haha.

@lehoeven Disabling SIP somehow fixed this? That's really interesting! How did you come to this solution? Do you have any idea why it might have helped? Anything you can tell me about this solution would be REALLY interesting. (Plus, also, I'd encourage you not to do it and to try the language-changing-dance above just to be sure 🙂 )

@dzm06 I found something online on an Apple related website that this fixed an issue about updating to MacOS Mojave, so I figured I’d give it a try. I believe it is similar to a solution I found for Windows when a security check program blocked Origin for some reason. I will try the language change thing next time I play and will come back to you! 🙂

@lehoeven Thanks!

@dzm06 Hi! I’ve enabled SIP and I changed my game language to English and the game is running! No initialization issues this time. Thank you for the suggestion. 🙂

@lehoeven Fantastic! Though honestly I'm still really curious why disabling SIP helped. That's ... odd.

I believe a better workaround has also been provided here: https://answers.ea.com/t5/Technical-Issues-Mac/Re-Sims-4-Initialization-error-at-startup-Legacy-Edition/m-p/8431767#M23545 if you'd like to play in your preferred language again.
