We attempted to upload a .dmg for Xcode 12.5.1 (approx 14GB) and hit an error:

<Error><Code>EntityTooLarge</Code>
<ProposedSize>13988766834</ProposedSize>.
<MaxSizeAllowed>5368709120</MaxSizeAllowed>
</Error>

The .xip file was downloaded from the Developer portal and unpacked in terminal using xip --expand.

Could the upload size be increased to 20GB to allow larger .dmgs to be delivered by SimpleMDM using Munki ?

Performance delivering Xcode from Apps & Books is patchy, and does not allow the running of a post install script to accept the licence and install the embedded packages.

This could be for a test instance initially to check performance.

Non-integrated munki and local mirrors may be the only reliable option.

We have other installers from Apple (Logic Loops) and Maxon (C4D) that may be over the current limits too.
