Hello,

I am running a Pharo 6 image (Latest update: #60498) on a mac sierra machine (10.12.1).

I loaded version 4.6.4 of OSProcess (which is the one loaded with stable version of CommandShell project).

I expected these methods to tell that I am running on a "mac unix" system:

OSProcess class >> isNonUnixMac

OSProcess class >> isUnix

OSProcess class >> isUnixMac

But they all answer that i am running on a "non unix mac" system.

Problem seems to come from the following check to decide if a mac platform is "unix mac" :

(self platformName = 'Mac OS') and: [numericOsVersion >= 1000]

In my case, numericOsVersion is '10.12.1' asInteger, which gives 10 => "non unix"

I broke this last week by changing getSystemAttribute: 1002 to answer e.g. '10.12.1' instead of '1095' which the old code (Mac call Gestalt IIRC) always returned.

I fixed it today by changing getSystemAttribute: 1002 to answer e.g. '1012.1' instead of '10.12.1', so '1012.1' asNumber >= 1000 once again. Apologies for the inconvenience. The next VMs which are built automatically should be fixed.
