Sierra Installation through Self Service

Uploading the installer and using it directly stopped working around 10.12.4. Try using a script.

I'm using the babodee one @hkabik mentioned. It is working on 10.12.6 too.

the normal 2 stage 1/ osx cache process and 2/ deployment using self service still works for me

Can confirm that the method that @cbrewer mentioned works well for us.

@cbrewer & @mark.mahabir I tried the script on a mac that had 10.11 and let it sit over night. I came back the next day and there was no change; it was stuck on the wait for 5-10 minutes for the computer to reboot.

I have a question in regards to the script. https://github.com/kc9wwh/macOSUpgrade/blob/master/macOSUpgrade.sh

Under the user variables, there's a section to link to a policy that will download the installer if it's missing. How do you get the name of a policy to pass with Jamf Pro? As in, how do I FIND the name of a policy that the script would understand?

Secondly, I had no idea we could do this in scripts.... That could be very powerful and allow me to create policies that daisy chain off one another...

@tnielsen If you're referring to $6 in the script, that isn't for the name of the policy. Use the policy ID or a custom trigger to call it. For example, say your "OSX-Sierra-Cache" policy has a custom trigger called "cache-Sierra" Enter that and the command that ends up being run is something like /usr/local/bin/jamf policy -trigger cache-Sierra As long as the machine is properly in scope, the script will call that policy and cache the installer, and then move on to the rest of the install.

Yes I am referring to $6. Can you tell me if this line of thought is accurate?

1. I create a policy that is set to execute upon a custom trigger, called "cache-Sierra". The policy is scoped to all computers for simplicity.
2. Computer "X" runs a script that executes a: jamf policy -event cache-Sierra command.
3. Computer "X" then runs the policy.

Is that an accurate line of thinking or am I missing anything?

Thank you @mm2270

Yes, that is essentially it. And to go a step further, in the above script that installs Sierra, it can call that policy with /usr/local/bin/jamf policy -trigger cache-Sierra so it will run that policy, complete it, then continue running the rest of the policy that installs Sierra.

Keep in mind though that that is only provided as a method for correcting anomalies. The Sierra installer should be cached using a separate regular policy on eligible devices or devices enrolled in your upgrade plan, so when they run the "Upgrade to Sierra" policy from Self Service, it just works.

@cbrewer I use the https://github.com/kc9wwh/macOSUpgrade also to install High Sierra via Self Service, but is there anyway to remove the popup that notifies the user that the OS has to be downloaded and the user has to click OK??? I don't want them to have to click anything, just download it, going straight to the custom event.

I probably would think just remove the 3 lines of code above

Run policy to cache installer

here is that section of code in the script

##Download OS installer if needed if [ $downloadOS = "Yes" ]; then /Library/Application Support/JAMF/bin/jamfHelper.app/Contents/MacOS/jamfHelper -windowType utility -title "$title" -alignHeading center -alignDescription left -description "$dldescription" -button1 Ok -defaultButton 1 -icon "/System/Library/CoreServices/CoreTypes.bundle/Contents/Resources/SidebarDownloadsFolder.icns" -iconSize 100 ##Run policy to cache installer /usr/local/jamf/bin/jamf policy -event $download_trigger else /bin/echo "$macOSname installer with $version was already present, continuing..." fi

I have tried the macOSUpgrade but it has not worked in my tests. I have stripped out everything to make it really simple (and maybe easier to see where the problem is)

I have a package that places 'Install macOS Sierra.app' (10.12.6) in the applications folder

That package is cached on a machine

A smart group is made of 'Computers with Install macOS Sierra' cached

Then I have a policy that installs the cached package and then runs the script.

I get the dialog boxes for about 5 minutes then nothing ... it goes back to self service

Does this script look correct? Any assistance would be greatly appreciated.
