Original GitHub issue: https://github.com/keycastr/keycastr/issues/95

I've just installed Keycastr v0.9.4 on a Mac with OS Sierra 10.12.6.

When I try to run the application I get a "Catastrophic Error Encountered - Could not create event tap" message.

I tried clicking on "Grant Access" and type in my password, but the message keeps showing.

I've tried to install Keycastr via homebrew and by downloading the .app file, error pops up either way.
