How to completely remove camtwist?

Hi,

The .dmg you download should either have an Uninstaller included or the Installer should have an Uninstaller option if there is not a separate one.

Some people download it to be able to switch between two cameras in apps like Messages or Photo Booth or even FaceTime

I am not sure which app has the choice of Camera above the preview as you have posted.

Many people find AppZapper useful if they have lost the Uninstaller

You may find that some apps still show the option in camera choice drop downs as it will be referenced in the .plists

Hi,

At one point there were several Add-ons for iChat.

Chax was one but has not made it past Snow Leopard.

There used to be ShowMacster (did what iChat Theatre Did later) and some others.

These may be still listed in the Com.apple.ichat.plist that Messages still uses.

To access open an Finder window.

Use the Go Menu whilst holding down the ALT key.

Select the Library that appears in the list.

Navigate to Preferences.

Find the .plist and Drag it to the Trash.

Restart the app and the .plist will be recreated.

However first I would restart the Mac after removing Camtwist.

How dis you remove Camtwist ?

Just dragging the item from Applications to the Trash probably will not cut it.

Hi,

I added this as an Edit earlier.

Ok as the effected app is Skype find the Skype .plist

As it is not an Apple it will not start com.apple

I don't use Skype so I can't tell you the precise name.

It is also late where I am and it is going to be some time before I pick up on replies.

Hi,

Do you happen to still have the .dmg ?

You could open this so it show the white Drive like icon on the Desktop and the window and see if it lists an Uninstaller.

Example for Little Snitch

Flip4Mac on the other hand needs the Installer to be run but in the Folder it creates in the Application foler there is an Uninstaller

I have never downloaded Camtwist to see if I have the .dmg to find out.

Camtwist installs a command in the same folder as the application which removes the app and the driver completely.

Open the Camtwist folder inside the Applications folder and double click on the uninstall command. It will get rid of it.

>> "Camtwist installs a command in the same folder as the application which removes the app and the driver completely."

If only that would be the case. It doesn't uninstall completely and Skype still crashes upon launch after using the uninstaller.

You can uninstall it and make Skype start again by first using the uninstaller, then

opening a Terminal and running

cd /Library/CoreMediaIO/Plug-Ins/DAL

sudo rm -r CamTwist.plugin/

Skype works again after that on my machine.

Hi,

It is more likely that such an Add-on would place a Plugin where it could be linked to the use of the Camera rather than every app that has access to the camera.

There are two possibles when this sort of thing happens.

1) the .plist for the app still carries a references to using the removed item in such a way that the process collapses.

2) the Plugin is not removed by the Installer.

There is a third in that an Upgrade may move the contents of a Folder or rename a folder used by these apps and the Add-On loses track of that and looks in the wrong place for the plugin.

As your post has been edited I see you have found a solution.

Step 1: open CamTwist

Step 2: right click on CamTwist (in Dock) and click Options, Show in Finder

Step 3: open the uninstall terminal window and enter your password (password dosen't show up, but still is getting typed)

Step 4: Done!
