Hello I keep getting error codes 21:0 on my Mac to play sim4
the game will not launch and I have tried uninstalling origins many times. its been more then a month now.
@Magnificent5star Try running the Origin reset tool for Macs:
If that doesn't help, are you running an older version of macOS? Players on Yosemite have had success downloading a legacy version of Origin instead of the current one. More details are in this thread:
If that doesn't help, it would be great if you could post in that thread, listing your OS and attaching the Origin logs requested in the first post. That's the master thread, and it will be updated as soon as there's a solution.
