Desperately trying to remove CamTwist

[sadakxp]

I've read every post I could find, and none of the solutions help me. They all seem to be from a few years ago, and maybe that's why those solutions don't work anymore.

I've installed CamTwist long time ago and now that I've deleted it, I was expecting to only have the built-in camera available for selection. But CamTwist is still there and it doesn't allow me to change to the built-in camera in any browser. I'm desperate.

Does anyone have any ideas how I can solve this? I'm on macOS Big Sur.

Remove the CamTwist Plugin and delete the app from Application folder.

sudo rm -rf /Library/CoreMediaIO/Plug-Ins/DAL/CamTwist.plugin

Works for me in Big Sur. If it still shows up in your browser, it's cached somewhere there.

The plugin is not in that folder though. The CoreMediaI0 folder doesn't seem to exist, not even when I go there manually.

Well, that is odd. It's there on Big Sur for me, not sure if they relocated it for fresh installs, but upgrading from previous versions that's where it should be and I can't see why it wouldn't be there on Big Sur. Do a system wide search for the plugin and remove it where it shows up.

Try pasting this exact command line into a Terminal window:

ls -ld {/Library,/System/Library,~/Library}/Core*

This looks for any subdir with a name starting with "Core", in each of 3 different places:
/Library
/System/Library
your user Library

If it finds one in any of those locations, it lists it out, but doesn't list its contents. I suggest pasting the complete output here, so others can see it.

The idea here is simply to find if any of the 3 locations even has a directory with the correct name. If one does, then you can go there and see what's in it. If none do, then it will at least clarify whether the expected dir even exists.

I used "EasyFind" to search and found this:

Easyfind is a small FREE utility and you can get it here:

DEVONtechnologies | Needful Things

A little collection of free utilities for the Mac to make your life easier.

You can ignore the "alias" files above, I made those.
But the rest seem to have been installed by the CamTwist app, and if you really want to "be rid of it", you need to delete each one.

Thank you, this has been very helpful and I finally managed to get rid of it. Apparently the plugin was also in another directory and the command you gave me helped me find it. I'm very thankful. Thanks a lot!

OP:

If all you did was remove that one file, remnants of CamTwist are "still there".
See my reply 6 on how to find and get rid of them...
