Fix iGlasses virtual camera on Zoom (OSX)
Let's make app for Mac to accept iGlasses or any other virtual camera again on a Mac.

First, make sure you have Xcode installed, then just open a Terminal window and run the following:
sudo codesign --remove-signature /Applications/
Restart Zoom andyou should have any of your virtual cameras available again.
Install Git completion on Mac OSX
If you're like me and use the command line for everything Git, then you are missing the autocompletion when on a Mac. So, if you are using zsh, and you should, it's super simple, just install ohmyzsh:
sh -c "$(curl -fsSL"
Otherwise, if you are still using bash (goodie but oldie), then let's add autocompletion via Homebrew:
brew install bash-completion
Then add the following to ~/.bash_profile
if [ -f `brew --prefix`/etc/bash_completion.d/git-completion.bash ]; then
  . `brew --prefix`/etc/bash_completion.d/git-completion.bash
Restart your terminal and try to type git checkout or git branch, then hit the TAB to have a list of available branches. It’s very similar to the built in bash autocomplete for files and folders.
Git branch: create and checkout at once
Step by step requires two commands, therefore a lot of typing involved:
git branch new-branch
git checkout new-branch
You can do it way simpler, by switching to it immediately after creation
git checkout -b new-branch
What's not to love about Git?
