What happened?

Hi, I'm having an issue trying run 2.4.0 (I haven't tried earlier builds). I first installed via Homebrew, then tried from the DMG. Same results. When running the app from my /Applications folder nothing happens. The screen has a brief flash; I see the icon momentarily in the Dock. Then nothing. I cannot see any mention of Barrier in the logs.

I've also tried this from the command line: open -n -F -a Barrier. No difference. I checked and it's not being blocked in the Security & Privacy settings (I may have gotten a dialog box initially asking if I wanted to allow it, but I don't recall).

Version

v2.4.0

I don't know if this will help you, but you may have better luck with 2.3.3:

I recently upgraded to Monterey 12.1 from Big Sur. An existing configuration with 2.3.3 survived the upgrade and was working fine. Then I upgraded to 2.4.0 and it broke my setup across all clients. Windows 10 is my server and Monterey and another Windows 10 box are clients. Mousing to clients would capture my mouse, the mouse cursor would disappear from all machines, and attempting to mouse back to the server would never release the mouse and keyboard from the client. Clicks would have effects on whichever client captured the input, but they happened at some fixed locations and moving the mouse would not change that location.

I downgraded back to 2.3.3 and everything is working again.

Thanks for the suggestion @chuckrector. Unfortunately 2.3.3 does the same thing. (I completely uninstalled Barrier using AppCleaner first).

Using 2.4.0 without any issues. You just need to make sure to create a SSL certificate (whether you activate SSL or not!):

cd ~/Library/Application\ Support/barrier/SSL/             # should exist..if not create it
openssl req -x509 -nodes -days 365 -subj /CN=Barrier -newkey rsa:4096 -keyout Barrier.pem -out Barrier.pem

( source https://github.com/debauchee/barrier/issues/231#issuecomment-962421337 )

I use this script to install Barrier:

#!/bin/bash

set -e
set -x

if ! brew list --cask barrier > /dev/null; then
  brew install barrier
fi

if [ ! -f "$HOME/Library/Application Support/barrier/SSL/Barrier.pem" ]; then
  mkdir -p "$HOME/Library/Application Support/barrier/SSL/"
  cd "$HOME/Library/Application Support/barrier/SSL/"
  openssl req -x509 -nodes -days 365 -subj /CN=Barrier -newkey rsa:4096 -keyout Barrier.pem -out Barrier.pem
fi

@hacfi Thank you, this saved my day!

Is this a bug with Barrier or with the homebrew bundling of Barrier?

This is what worked for me but i did some searchings and found another post where it was mentioned that 2.3.2 will generate the pem files and ssl fingerprints then we can upgrade to higher version. So i installed 2.3.2 first and then replaced what with 2.3.3 and now everything works fine. Whoever facing a lag in mac os, they can use 2.3.3 and its working. I am using big sur in one mac and monterey in another.

Hi, I have trouble on Monterey, it started of working with my first windows 11 as client, then when I added windows 10 client it seems like it crashed, and now my Mac Monterey kinda restarts all the time, how can I completely remove and reinstall Barrier on the Mac? I use the mac as the main "server" for the Mouse. Thank you in advance.
