LTSPICE MAC standard files replacement

hi All

I installed LTSPICE on a MAC with Mojave and i would like to replace the standard models in the /lib/cmp directory by the improved version from here http://ltwiki.org/files/Standard.zip

unfortunately when i replace the files or even delete them, only the old models content appear in LTPICE (just like if they were built in the binary !!!)

for example i wish to simulate with a BFR193 model, but the default standard.bjt file does not contains such a device.

the replacement of these files works perfectely on a PC but the MAC it seems not to work as expected.

any idea ?

Best regards
