How to launch an offline inventory on MAC

Hello everyone

So here is my problem : I don't know how to create an offline inventory  log file (.OCS)on a Mac OS X supported machine .

There is no option for offline installation (unlike the Windows Agent).

On this site I have found this thread(https://ask.ocsinventory-ng.org/2400/macos-x-agent-offline-installation?show=2400#q2400 )but the answer is not working (or lack more instruction on how or where to do it )

So any help would be gladly accepted

Thanks
