Microsoft announced this week that Service Pack 1 for SCCM 2012 would be released in Q3. In addition to the expected support for Windows 8, they've added support for Mac OS X and Linux. Yes, really.
The announcement was at TechEd America 2012, but I found out about it at the Best of MMS event in Edinburgh being run by Charteris. The Microsoft guy I spoke to confirmed that Endpoint Protection is part of this support. Yes, that's a Microsoft antimalware solution for your Mac and Linux machines!
