Release : 14.3 RU2 [14.3.4615.2000]
SEP 14.3 RU2 MAC Client package cannot be imported in SEPM.
With the new feature introduced in SEP 14.3 RU2, "Client patch Support" Client packages will automatically get downloaded in SEPM.
Running LiveUpdate from a pre-14.3 RU2 SEPM (like 14.3.3385.1000) will not update the 14.3 RU2 package automatically.
Upgrade SEPM to 14.3 RU2 and run LiveUpdate.
