If the payment terminal cannot be connected and the debug logs show the error:
"Payment terminal could not be initialized (pos.xml)", the issue is usually related to the location or permissions of the configuration file.
How to resolve the issue:
verify that the
pos.xmlfile is located in the following folder:/Library/Application Support/Flexi/Default
make sure this is the system-level (root) Library folder, not the user library 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 them:
/Library/Application Support/Flexi//Library/Application Support/Flexi/Default
