I’ve successfully created a workflow to install macOS Mojave 10.14.4 and several software using MDS from an external LACIE portable drive connected to the Mac via thunderbolt.
I have run this MDS workflow successfully over 5 times on a Late 2013 Mac Pro (black trash can model) as well as an iMac i7 Late 2015.
When I attempted to run the same MDS workflow, from the Lacie Drive, on a straight out of the box iMac i9 2019, the workflow got past prompting for the computer name but then stopped when it attempted to run the macOS Mojave installer. Error: Your version of MacOS 10.14.4 cannot be installed on this system.
No user prompts to terminate, waited over 20 minutes and ended up Cold booting the iMac.
Now the iMac i9 2019 was purchased before the release of Mojave 10.14.5. My guess is that the iMac i9 2019 was released with 10.14.3 or 10.14.4 maybe older. My questions are:
if the macOS installer is applying the same OS version that is on the out of the box iMac, would this generate the error I got and holt the entire workflow?
Also to add, when I used the same Lacie external drive, I had to use the USB3 to connect to the iMac 2019 since there are no longer any thunderbolt ports on this model. Just USB and USBC. would that also cause the installer to fail during OS install?
Please advise. Thank you
