Why should I allow the access to Screen Recording when start mirror to Roku?

If you try to mirror to Roku at the first time, the system will ask you to allow to record computer's screen. That's because the app will record your screen then push the stream to your Roku device for mirroring. It don’t record your screen into files and don’t send any content to a server. It only temporarily store data in the memory of your device before it is streamed to TV. Upon streaming, the content is removed from memory.

If you choose "Deny" at the first time, to make the mirror work, you should allow screen recording manually:

1.Please open "System Preferences" and go to "Security & Privacy"

2.Select "Privacy" Tab, then choose "Screen Recording" on the left side.

3.Check the Omi Mirror app on the right table list.

4.Restart app.
