My computer OS just updated to Tahoe 26.1. After the update,

I cannot cast my entire screen from Google Chrome web browser on the a Google Chromecast.

I can cast the tab, but I cannot cast the entire screen anymore. Whenever I try, it tries to connect and gives me a black screen and never connects. I don't think it's the Mac Privacy / Security Permissions or the Hardware Acceleration issue. I've seen previous users deal with similar things on different OS. I've tried their solutions and it still is not working. This appears to be new thing specially with Tahoe 26.1.

For your third party app—if in doubt search the developers website or contact their: Support/Help/FAQ/Known issues/compatibility/updates…

Contact a third-party vendor - Apple Support

Unfortunately, I do not think it's a third party issue. I cannot share my screen in Zoom or other similar type platforms.

google chrome and chromecast are BOTH third party solutions.
