Newer iMac booting to circle with slash through it

Trying to boot to USB DeployRuntime on new 27” iMac with Retina 5k display, but after I select the DeployRuntime drive, it goes straight to a circle with a slash through it.

-    The DS server is on 1.7.5 and running Sierra
-    I can image new USB-C MacBooks without any issues

Re: Newer iMac booting to circle with slash through it

did you create the deploystudio boot disk on a 10.12.5 system? The circle with line means it does not have the drivers for that model. You'll need to create a new boot disk on the correct hardware.

Re: Newer iMac booting to circle with slash through it

Just checked the server and it's on 10.12.3.  I'm in the process of updating now.  Thanks

Re: Newer iMac booting to circle with slash through it

If you're partitioning the drive and laying down a DMG in your deploystudio workflow with something like AutoDMG .... more than likely you're also dealing with a different build of sierra since you mentioned a new iMac. I just got 70 new iMac's with 5k screens. Made a new netboot set and after they run through deploy studio and reboot, they come right back to the circle with a slash and never get to the deploystudio install process. The build of sierra from the App store is 10.12.5 (16F73). These new iMacs are are newer and you can't download the build specific version of sierra, even if you have a paid developer account.

You have a couple choices based on your workflow. After it reboots to the circle/slash. Shutdown and then boot into recovery mode. Then re-install Sierra from the recovery mode. It won't erase the DS workflow and after Sierra installs it will finish the workflow. Wait for Apple to release 10.12.6 to unify all the builds. Or, modify your DS workflow so that new machines don't get the drives erased and partitioned and you only install packages.

Re: Newer iMac booting to circle with slash through it

I upgraded the server to 10.12.5 and the iMac and Server now match.  Created a new USB, but still get the error.  We don't use Netboot or AutoDMG.  When we create a new image or update, we just create a new master image via deploy studio.  This server was configured prior to me taking it over.  We create USB DeployRuntime USB drives instead of using NetBoot.  I had the same issue when we first go the USB-C MacBooks.  After I upgraded the server to Sierra and also updated the recovery partition, I was able to boot to the deploystudioruntime usb and create a master image.

16F2073 is the same build for ALL the new macs. If you build the the Deploystudio boot disk/Netboot on one of them they will work on all the macs that support sierra (including the new ones)

Re: Newer iMac booting to circle with slash through it

Thanks for the info.  Our server is for sure an older build, so that's the issue. Typically when we image or create images, we create an external DeployRuntime usb, boot up to that, type the server IP and credentials and select our current image to pull down or to create a master and it uploads it to the server.  Since the iMac is the newer model, I'm unable to create a master, because it can't boot to it.

Re: Newer iMac booting to circle with slash through it

Any ideas how can get create an image for the hardware model since the DS external drive doesn't boot up to the point where I can create a new master?

Re: Newer iMac booting to circle with slash through it

This method that generally works (but I did read that 10.12.6 generic does not always boot the 2017 iMac).

1-Use AutoDMG to create a dmg for the latest OS.
2-On the server (to have same version of DeployStudio, preferably latest): mount this dmg (check that your local HD is NOT called " Macintosh HD" to prevent confusion with the mounted image)
3-run the Assistant to create an USB drive, but take the mounted image (usually named Macintosh HD) as source.

(reason: this image has always the same version os of the Recovery HD, and DeployStudio takes files from the recovery HD)

I used this method to make Netboot sets, but I guess it works for USB too.

Let us know how it works out for you.

Re: Newer iMac booting to circle with slash through it

Thanks that worked, but now I'm running it to where it's telling me I need a critical update to run. I was able to run the critical update and everything went through.  I was able to create a master image and image the new mac book with it, but when I try the second time to test, it prompts for the critical idea, but I created the image after that update was done.

Re: Newer iMac booting to circle with slash through it

that message is the embedded OS for the touchbar that wants to activate.
If you do not erase the disk but restore to partition (leave the EFI partition in place) it may help to avoid this message of the critical update.
But like firmware, the embedded OS must be updated for security reasons,so is not avoidable.
You can try to do this during deployment so the end-user does not have to do them (for now, untill new updates arrive)

Re: Newer iMac booting to circle with slash through it

Just want to say thanks again on you assist.  Doing the update during the image process isn't a big deal, I'm just glad I can image them.
