Is there a technical solution to fix this?
No. Apple wants users to purposely enable access to the microphone or camera.
What device and operating system does this effect?
This issue affects ANY mac computers that run macOS Mojave
How do we fix it?
Crowdsourcing. I volunteer to help but teachers and students can grant the necessary access with guidance.
How?
Go to System Preferences --> Security & Privacy --> Privacy --> Microphone.
Check the OaksSecureBrowser option, if it is AVAILABLE.
I do NOT see the OaksSecureBrowser option, what to do next?
The option only becomes available after the microphone access is being triggered once.
Launch the OaksSecureBrowser app --> Go to the Sample Test Site --> Run Diagnostics --> Recording and Playback Check --> Click the Speaker icon to do the speaker check --> Click the Recording icon to do microphone check --> Click OK to grant permission when OaksSecureBrowser asks to access the microphone.
I'm putting together a KB article. Please look through and distribute to teachers.
NOTE:
- This issue only affects Mac computers that run on Mojave.
- The microphone access option should get enabled by default if the users click OK when being prompt
