Hi all,

I have a problem with Mac OS X deployment. I captured ASR image from a master I created and when I try to deploy this ASR image I have an error "Checksum failed."...

Have someone a little bit experience with Mac OS X deployment ? I made 3 trials but just the second one successed... I just use the pre-install task "Create a simple HFS+ partition on disk0" but the deployment process failed during "Apply image" task. Here is the log file:

Wed Jun  8 04:21:05 PDT 2016
Start of image deployment via ASR.
ls -l /Volumes prior to ASR invocation ...

Deployment failed with err=1

Has someone an idea to resolve or maybe identfy the problem?

Thank you in advance for your help...!

  • I am working with Dell Kace on this now. I am having a similar problem deploying to iMacs with fusion drives. I can capture ASR and K images without issue, but I have not been able to successfully deploy any of them. What amazes me, is that the Apple online re-installation of Yosemite works flawlessly. I am also amazed at how difficult it is to find documentation, or at least a simple step-wise process to do this.
  • I completely erase disk and reinstall OS X manually to make my master image and I don't have this problem anymore. The problems was probably due the recovery partition.
    I also have a problem with fusion drive... Impossible to capture image from it but I don't have problem to deploy on it.
