KB: You cannot install applications larger than 4 GB on a Mac by using the System Center Configuration Manager client


When you try to install an application package (.cmmac file) that is larger than 4 gigabytes (GB) on an Apple Mac by using the ConfigMgr 2007 or ConfigMgr 2012 client, the package cannot be extracted. This issue occurs because the unzip tool located in "/usr/bin/unzip" does not support extracting files that are larger than 4 GB, even though the inbox ZIP utility can create a compressed (.zip) file that is larger than 4 GB. As of 8/19/2014, this is a known issue of using the System Center Configuration Manager client on a Mac. The issue will be fixed when an updated unzip tool that supports large files is available for Mac.

For all the details and the latest information regarding this issue, please see the following:

    Perhaps use of tar/gzip or DMG would have been more appropriate?

    Thanks for the heads up.

    Still think mac support in sccm needs a bit more TLC

    Pretty big cop out to say we’re waiting for an updated unzip tool. Considering the last update to the unzip binary was in 2005, I don’t think you are going to get that update! How about you use another tool that is available that will do the job? As noted
    above -^ tar/gzip or dmg would be fine.
