Could be due to slow download speed from the distribution server, this is a known error and is due to Apple ASR apparently. I had this problem when I used a USB to Ethernet adapter but when I swapped to a Thunderbolt to Ethernet (or just used the Ethernet port) it worked fine. So make sure you have a fast connection between distribution server and the machine running casper imaging.

So this has started happening to me now. 10.10.3, JSS (et al) 9.65...

Everything happens normally, but the 'please wait whilst I install' splash screen just stays up for far too long, more than an hour (normally we're done in 20 minutes max). I quit it and restart the Mac and it boots back into the Temporary Adobe Installer (TAI). But it's already enrolled and everything, which means the FirstRun stuff is gone, which also means whatever is supposed to remove the TAI is gone.

Now that I think about this, I should start a new discussion, since this is not really the same issue as the OP.

I am experiencing this problem now using 10.10.5 and 9.8.1. It just hangs here.

Are you using Casper Imaging 9.8.1 also? I had that happen when we upgraded the JSS but hadn't upgraded out imaging netboot image yet.

This was happening to us when we upgraded from 9.72 to 9.81. We were still using the 9.72 imaging in our netboot, and spinning up a new nbi with 9.81 Imaging solved it.

Yes, in retrospect almost all of the instances that we had where this happened was because someone was using a version of Casper Imaging that didn't match the version of the JSS. As soon as they upgraded and re-imaged, it was all good.

@jhbush1973 I appreciate your post and script. I'm getting this a lot with OS X 10.11.6 and Casper 9.96. I created the package but where in the chain do I place it to install and also to make sure I set it up right, what type of script am I putting in the package, Preflight, etc?

Thank you for the great advice. Have a great day!

@skinford It's a postinstall script

@aporlebeke Thank you!

Just chiming in here.

We found that fixing the TimeZone in the Netboot image resolved this and also brought back the "The imaging process is finishing installing software" background during the OS deployment.

This happens when re-imaging ... If the entry isn't deleted from the JSS before re-Imaging, the above will occur..

my tuppence worth :-)

There is also a bug that causes this when Casper Imaging tries to create the management user via the settings in the Casper Admin config.

@jhuhmann Is there anyway to create the management account other than as part of the configuration image? I'm experiencing the same issue.

@rqomsiya Yes. You can set the configuration to specify the account but don't tell it to create the account, then use something like this: https://github.com/MagerValp/CreateUserPkg to create your user account.

It's been a bug since 9.72, which came out 2 years ago. I wouldn't hold your breath on it getting fixed.

So I realize this is an older thread but I am still having this issue of the JAMF temporary account being logged into and shown instead of showing the JAMF Imaging screen. I have tried the following:

1) Created an empty package except for a post flight script per:
[https://www.jamf.com/jamf-nation/discussions/5600/inconsistent-the-imaging-process-is-finishing-installing-software-at-imaging#responseChild30922](link URL)
2) Created that same package but with a postinstall script
3) Following @jhuhmann suggestion, I set my configuration to specify the management account but don't tell it to create the account and then I used CreateUserPkg to create the management account.
4) Even tried the above management settings but create the user with a script.
5) I don't feel like removing the entry from the JSS will work because then that would delete the AutoRun Settings which I use to image with.

I'm not sure what else to try. Imaging still finishes fine but surely there is a way to get this to stop showing the JAMF Temporary login and start showing the JAMF Imaging Splash Screen.
