To upgrade our clients to High Sierra we used to
- push High Sierra.app via VPP to all eligible clients
- have a smart group that monitors if a device has the installer
- a policy scoped on that group that runs the installer.
Since last week the policy failed.
The cause: sometime last week Apple started pushing a 19.6mb Install High Sierra.app that, upon launch caches the InstallESD to /MacintoshHD/Install Data, instead of an Install app that contains the InstallESD.dmg.
Any workarounds that still leverage local caching servers to cache Install High Sierra or InstallESD to clients that do not require me to manually upload the ESD to our Amazon Distribution Point? I'd like to leverage local caching to reduce bandwidth and improve speed.
