In macOS 10.14, 10.15, and MacOS 11, iGlasses will not show up in certain applications. Apple has introduced the concept of a Hardened Runtime and Library Validation. This prevents hardened apps, from loading any 3rd-party add-ons such as iGlasses.
Apps that currently do not load virtual cameras include:
Safari (Use Chrome instead.)
FaceTime
Skype (See Skype workarounds.)
MS Teams (See Teams workarounds.)
Webex
Quicktime (Does not support iGlasses, or other virtual cameras, on MacOS 11)
We are not able to update iGlasses for compatibility with the Apple applications mentioned above.
