Mac Screen Sharing Permissions
When your presenter is on a Mac, and when he/she shared the screen, sometimes, it may not appear. The indications are as follows.
- The preview is not appearing in the AV Controls panel for him/herself
- Others are seeing a blank/white screen
This guide helps to fix the problem.
This problem arises due to Mac OS Permissions
