Deploy Wallpaper to M1 Macs

[SebastianH]

I've been trying to distribute backgrounds to the M1 Macs for days. but unfortunately these M1s behave completely opposite to the Intels.

Log says "Completed" but on the M1 is only a blue background instead of the distributed background.

all Intel Macs have the new background loaded.

I have tried both ways as PKG & DMG both are successful on the Intels, but not on the M1.

what am i doing wrong ?

Since M1, is your installer from composer universal? or do you have Rosseta 2 installed? that can cause it to fail.

We were running into similar issues with M1 Macs. I decided to venture out and and go with a command line tool called Desktoppr discussed in the thread below:

It has been rock solid for Mojave, Catalina and Big Sur and works for both Intel and Apple Silicon. https://github.com/scriptingosx/desktoppr

Otherwise I think @SmilieK 's suggestion on making sure the PKG is universal is a good one.

thanks guys tried both ways. just repacked the Wallpaper to PKG -> Works (dont know why, but now it works)
desktoppr also works.

Thanks for your help
