On macOS, you may find that it is not possible to type a decimal comma — when attempting to enter a comma, a period is entered instead.
To resolve this issue, you need to open the Info.plist file located at /Applications/FlexiBee.app/Contents/Info.plist
(To open FlexiBee.app, right-click it — or use Ctrl + left mouse button — and select "Show Package Contents")
and add the following parameters to it:
<string>-Duser.country=CZ</string>
<string>-Duser.language=cs</string>
Add the parameters below the -Xmx800m parameter near the bottom of the file (if you have previously adjusted the memory allocated to Java, the value 800m may differ).
