We are tracking an issue where the current version of Skype, version 8.60, does not load virtual camera devices on macOS 10.14 or macOS 10.5. While we are investigating this issue, there are two options to work around this:
Option 1: Use An Old Older Version of Skype
Older versions of Skype, such as version 8.59 will still load iGlasses:
Open Skype 8.59 directly from its disk image rather than from your Applications folder to prevent Skype from automatically updating to newer version.
(When you see this window above, double-click the Skype icon rather than dragging it to the Applications folder.)
Option 2: Remove Skype's Code Signature
Removing Skype's code signature is another way to re-enable virtual cameras. To do this:
1) Quit Skype.
2) Open the Terminal app, found in Applications -> Utilities.
3) Copy and paste this command into Terminal and then press return:
codesign --remove-signature "/Applications/Skype.app/Contents/Frameworks/Skype Helper (Renderer).app"
4) Re-open Skype.
Still Not Showing Up?
