To compress use 'Convert' in Disk Utility to remove the excess bloat.

Side note: I had success in the next step with using either as-is or a compressed final image. Now, using that image one can then restore to either a whole SSD, or a volume in a select APFS container on a your target SSD.This two step process replaces the previous and far simpler one step process to make an image of a volume. Select that image at the bottom left column of Disk Utility and restore with your source volume (in my case was a test OS install from my externally connected SSD).For settings: single partition, read/write In Disk Utility (Monterey restore mode), make a blank APFS image with approx 20-30GB padding with respect to the size of your source volume, and save to your MBP.The clone and restore process went like this: Perhaps there is a more elegant way to do this using terminal. It appears one can deliberately boot into Monterey's restore mode (as appose to Mojave's) by restarting while in Monterey, then instantly holding down cmd-r, and continue to do so well after the chime and until the darker UI appears. I only used Monterey for the purposes of cloning/eventual restoring a volume with Mojave installed, which unlike Monterey gets along fine with my 5,1). I connected my 5,1 SSD using a USB3 external case. I could only do this on my 2015 MBP (presumably any other Monterey compatible MBP would suffice, I didn't try this on one patched to accomodate Monterey). The solution that worked for me was to use the newest version of Disk Utility (v21) within Restore mode of Monterey - so if Mojave is installed, establish a partition on a MBP with a fresh, legit install of Monterey. No amount of trial and error in Mojave's restore mode worked reliably. Or.inapropriate ioctl for device, blah blah (OSStatus error 206.) Errors looking like this:ĪPFS inverter failed to invert the volume - Invalid argument Problem: persistent errors cloning and restoring APFS bootable partition for Mac Pro 5,1 (but could also be just as applicable to MBPs running Mojave 10.14.x?). This took me hours of trial and error to accomplish through use of a 2015 MBP.no idea why so problematic with Mojave's restore mode in order to save a fully configured OS installation as a disk image for future restores (for say, an SSD failure or capacity upgrade), who wants to do that all over again? For me a clone is more straight forward and trustworthy than using Time Machine, and faster then a file duplication approach. A response and potential solution to a previous post with a similar header.
