I’m having problems deploying Mojave/Catalina on older MacBook Pros and iMacs (2013-2014 model).
CMD +R = boots into ElCaptain’s recovery, which is too old for MDS.
Option + CMD + R = boots into Big Sur recovery, and does not allow me to install anything other than Big Sur (“startosinstall failed with return code 108”).
Any suggestions on how to get Mojave or Catalina on these units? I rather not use Time Capsules or DeployStudio.
