Custom localization strings ClientUI on Mac

I have been able to customize the ClientUI for windows by replacing strings in the en.xlat file. But when I try to do the same for the Macintosh OS I get no changes.

Has anybody been able to customize the strings used in the ClientUI for Macs? Or is this only an option in Windows?

The Mac has the file that should allow the changes, but it is in a totally different spot than the Windows counterpart. I am looking to change the title that comes up on the ClientUI to something besides “IBM BigFix Support Center”.

Thank you.
