Assets Scan - MAC OS X 10.11.6

Hello everyone

I have problem with assets scan.
Problem is related with specific version os, exactly MAC OS X 10.11.6 (but I haven't get any problem for example with MAC OS 10.6.8, MAC OS 10.9.5, MAC OS 10.12.6). It looks like it can scan machine but there is not software listed...
Credentials are OK.
Does anyone have meet with thiss issue ?
