Running Mac OS from a USB or external drive | Dr. Sachin Dev Duggal
Hello Everyone,
Myself Dr. Sachin Dev Duggal, This is my first post!
I have two older (2017), 15" Macbook Pro devices with Monterey as the OS.
Is it possible to make an image of device#1 and run that image from a USB or external drive on device#2?
I've tried a couple tutorials online but no love (likely me not understanding instructions). After imaging 500GB stick from device#1 and attempting to boot from it on device#2, I can select the USB device from the startup options screen but the OS on the USB will not boot.
Basically, it goes:
For some more detail, when I boot device#2, I hold the option key till I see the boot device selection screen. The USB is seen by the device and is shown as a separate icon on screen. After selecting the 500GBDrive, the device will only show a black screen with a circled "X" and an address for what I'm assuming is Apple's official "how to boot" page.

Basically, it goes:
- Format USB as Mac OS Extended (Journaled) + GUID Partition.
- Create Monterey bootable USB installer (sudo /Applications/Install\ macOS\ Monterey.app/Contents/Resources/createinstallmedia --volume /Volumes/500GBDrive)
- Clone internal drive to USB (using Carbon Copy with changes only being cloned).
- Attempt boot from USB on device#2.
For some more detail, when I boot device#2, I hold the option key till I see the boot device selection screen. The USB is seen by the device and is shown as a separate icon on screen. After selecting the 500GBDrive, the device will only show a black screen with a circled "X" and an address for what I'm assuming is Apple's official "how to boot" page.
I'm know I'm doing something wrong, but can't seem to see it. Am I trying to do something that's not possible?
Please Help Me Out..
