site_archiver@lists.apple.com Delivered-To: installer-dev@lists.apple.com Hi Stephane, I'm seeing similar problems with pkg files that contain background on Mojave & Catalina: Installer[5550]: Package Authoring Error: <background> has an unsupported MIME type: image/data Installer[5550]: Package Authoring Error: <background_alignment> has an unsupported MIME type: X-NSObject/NSNumber Installer[5550]: Package Authoring Error: <background_scaling> has an unsupported MIME type: X-NSObject/NSNumber Installer[5550]: Package Authoring Error: <layout-direction> has an unsupported MIME type: X-NSObject/NSNumber I don't get where these errors are coming from, background in Distribution XML file is defined as: <background file="background.tiff" alignment="bottomleft" scaling="none" mime-type="image/tiff"/> I've tried to generate new pkg file on 10.15.2 with pkgbuild, still same Package Authoring Errors. Same errors appear on pkg files downloaded from Apple website, so I assume it's an Installer bug rather than pkg problem.

o Installer complains about Package Authoring Errors:

"Installer[881]: Package Authoring Error: <background_scaling> has an unsupported MIME type: X-NSObject/NSNumber"

The issue is that there are no background elements inside the installer-gui-script element of this distribution. Which is perfectly OK according to the official documentation (*)
