I have a USB Stick with Ubuntu Server 22.04 for Raspberry Pi (aarch64) installed on it. I am trying to back it up, and shrink the drive from a 128GB Drive to a much smaller file. I have the shrink option set properly in ApplePi Baker and when I start the cloning, It seems to shrink the partition and image filesize by barely anything. I have tried to shrink with both the stable version as well as the beta version of ApplePi Baker, and the cloned image just doesn't shrink. NOTE: I am saving the clone as a

.img

file, NOT a

.zip

file.

Could you help me figure out why ApplePi Baker is not shrinking it's clones?

Here is the output log from my most recent "unshrunken" image using ApplePi-Baker v2.3.0 (Build2), (Helper Tool version 1.9.2), on MacOS Version 15.3.2 (Build 24D81):
