NOTE: Casper Imaging 9.65 addresses this & as such the workaround is no longer needed.
Unfortunately, we have discovered an issue with Casper Imaging & Yosemite shipped Macs as these Macs come with CoreStorage enabled “Macintosh HD”. This has been logged with JAMF as D-008217 & this post will be updated once resolved.
To get around this defect, I’ve written a little AppleScript app called “CoreStorage Revert” that you can get via a PKG from here. (NOTE: This is for CoreStorage volumes & not Fusion drives).
The PKG is meant to be added to an AutoCasperNBI created NBI, as it removes the com.AutoCasperNBI.CasperImaging.plist as “CoreStorage Revert” launches Casper Imaging itself.
For more details on the app, the why & some rambling findings, see below.
