There's a step, or at least note, missing from the Test Scenarios for
ZENworks Patch Management doc in the SP2 Beta 1 Scenarios zip file when
it comes to Installing the Mac Agent.

Page 3, Test Scenario #2.

Step 4 should be done as root otherwise you'll get

Exiting with error code -1.
Exiting with error code 255.

FYI if you try installing the 32-bit agent on 64-bit Mac OS X you get

Package intended for 32 bit architecture
Exiting with error code 237.
