Intel Based Macs Failing to Update
Apple Silicon devices update without issue, but all Intel Based throw the following error using v4.0.3 of super
Software update command failed with an error: 2023-12-22 10:51:52.835 softwareupdate[54885:457369] XType: Using static font registry.
That is an error in softwareupdate not super
To be clear super can't "make softwareupdate fail less"... super can only try again later when softwareupdate does fail.
Unless you can provide more context, there isn't anything to fix here. Just another day where the Apple softwareupdate process breaks.
Please try the latest release of super as it may resolve this issue: https://github.com/Macjutsu/super/releases/tag/v4.1.0-beta1
There are many updates in https://github.com/Macjutsu/super/releases/tag/v5.0.0-beta2 that may resolve this behavior. Please try it out.
