If the payment terminal cannot be connected and the debug logs show the error:
"The payment terminal could not be initialized (pos.xml)", the problem is usually with the location or permissions of the configuration file.
How to resolve the issue:
verify that the file
pos.xmlis located in the folder:/Library/Application Support/Flexi/Default
make sure this is the system-level (root) Library folder, not the user folder (e.g. /Users/name/Library)
check the permissions for both the folder and the file (they must be readable by the application)
if the folders do not exist, create:
/Library/Application Support/Flexi//Library/Application Support/Flexi/Default
