This article describes an ongoing issue with a functionality that is out of CloudTalk's control. In the event that this issue is resolved by the relevant parties, this article will be updated and fixes for users (if necessary) will be provided.
When using certain versions of Apple's Macbook, the built-in microphone disables itself when the lid is closed. It should be noted that this is intended functionality according to Apple. See below for further information.
Due to the nature of the issue, this will only cause problems for users who work with their Macbook connected to an alternative screen and keep their Macbook itself closed.
Note: If you try to use an alternative primary input device instead of the Mac microphone, this will also be automatically disabled upon closing the lid of an affected Macbook.
Which Macbooks are affected by this?
This is an issue impacting any Macbooks with T2 security chips. To check if your Macbook has the T2 security chip, please refer to the following link: Mac models with T2 security chip.
Information from Apple regarding the intended functionality behind this behaviour
The following quote is taken from Apple's website and a link to the full page is provided below:
'The disconnect is designed to prevent any software — even with root or kernel privileges in macOS, and even the software on the T2 chip or other firmware — from engaging the microphone when the lid is closed.'
For more information directly from Apple, please refer to the following support page: Hardware microphone disconnect.
This only affects Macbooks, not Windows laptops.
We do not know if this behaviour will be changed by Apple due to it being an intended security-based functionality.
