Ever since I updated to Mac OS Catalina, Origin will not open

@hurricanyounot  What does the error message say?  If it's something to the effect that it be opened because Apple can't check it for malicious software, you just need to manually override the security setting.  Click the Apple icon in the upper left corner of your screen and select System Preferences, then Security & Privacy.  (For me, it's in the top row, third from the right.)  Under General, you should see a notification about any recently blocked app or download.  Click "open anyway," and you should be fine.  You may need to click the lock icon and input your computer password to make changes.

If the error message is different, please post a screenshot of it.

Haven't been able to sims in weeks.... I hope they're all ok. :P

I have the same problem, and once I click open it starts to load but is just a white screen...

@khoegler00  Try running the Origin reset tool for macOS:

And make sure you don't have any proxies enabled.  Here's how:

If these steps don't help, please list your version of macOS.

@deaashkea  If Origin doesn't open at all, click on the Apple icon in the upper left corner of your screen and select System Preferences.  Under Security & Privacy, you should see a notice about Origin being blocked.  (If it's not there, quit System Preferences, try to open Origin again, and then go back and look.)  Click the lock icon in the lower left corner of the window, enter your password to make changes, then click the option to allow Origin to open anyway.

If Origin does open but doesn't work normally, there are a few other steps you can try, even after the reset and disabling proxies didn't work.  Sign into Origin using your full email address or just your username, whichever you haven't been doing.

Please also temporarily disconnect any USB devices, just to see whether it helps.

If these steps don't work, you can try the others in this Origin troubleshooting thread:

If nothing else makes a difference, create a new admin user account on your Mac (make sure the name uses only letters and numbers, no special characters), and try to login using that account.
