If you see an error message when using Lightroom Classic saying your Loupedeck needs access to TCP ports but failed to make a connection, here’s what you can do.
Note! Before you proceed with the following steps, we recommend creating a backup of your current host's file.
- You can find your hosts file from the following path:
- Open Finder and click ‘Go’ from the Mac menu bar
- Select ‘Go to folder’
- Type /etc and click enter
- The hosts file should be in the /etc/ folder under the name 'hosts'; nothosts-orig, and notequiv.
- Find the new hosts file from this link
- Download and store it on your Desktop.
- Important! Please make sure there is NO file extension at the end of the file, for example, hosts.txt.
- Secondary clicking/right-clicking the hosts file
- Select 'Get info'
- Check under the 'name & extension' subheading whether there is any extension
- Make sure the 'Hide extension' box is unchecked
- Drag and drop the hosts file from the Desktop to the /etc/ folder
- You probably have to enter an admin password at this point. Please do it
- Your Mac will ask to replace the 'hosts' file already in the /etc/ folder. Please replace it
- You might need to reboot Mac if Loupedeck does not work instantaneously
