Boot to new laptop with SuperDuper

[thekaratehero]

I can't figure this out - thanks in advance.

I have a mid-2014 MBP and a newer macbook air (both have old school USB ports). Each has a USB hard drive that I superduper clone to. I can take one hard drive and boot it on another machine. THis is just my way to back up. If a machine dies or needs fixed - I can take its USB disk and boot the other laptop on it.

I got a brandy new MBP 13" a few weeks ago. I used the apple USB-C to USB adapter (with HDMI) to boot my mid-2014 MBP image on it. It sees it as a bootable image, but during boot fails and recovery says the disk is invalid.

I can boot the USB disk on my older MBP and my macbook air so its a good image.

I did turn on 'allow USB disk boot' on the new MBP. That at least let me get that far.

Is there something I need to do to get the new machine to boot the old USB image? Are the new machines incompatible with the old image or something?

Some key information is missing to make an evaluation.
What macOS is on the external SuperDuper! USB clone?
Is your new 13" MBP a 2019 (minimum macOS is Mojave)?

My WAG, is that the external SuperDuper! USB clone has an old macOS not supported by the new MBP.

The version of the OS may be too old to boot the new MacBook Pro.

The new MBP has a t2 chip, right?
Have you taken the necessary steps to DISABLE the t2 protection and permit booting from an external drive?
If not, boot to the recovery partition, go to Startup Security, and make the necessary changes.

I helped a friend get a new MBP. but it has to be compatible with his studio hardware, and that means High Sierra for him. He was told by Apple that the 2019 MBP was no good for anything before Mojave! I think it has something to do with part of the OS being in ROM. Take a look at Catalina and see that there are two major folders, but only visible in DU. I have tested Super Duper and CCC for clones up through Catalina, and both work fine in their latest versions. Here's a thought. In most cases, you cannot make a clone for an OS different from your working boot disk. You all probable knew that a long time before I did, but I never gave it much thought until I had to be using different OSs at different times. I will also say the Epson has done an excellent job with printer and scanner drivers. They finally had to replace EpsonScan as it used 32bit files. I know my 4990 works with Catalina, and it looks like my old 4870 will be brought back from the dead for the third time. Most of that equipment is on my cMP anyway and that can't go past Mojave.

Sorry for the slow reply - I had a thing. My bad.

My old MBP is on 10.14. I could try to update it and see if that works? I see I'm able to upgrade it. I didn't becuase I wasn't sure if my quickbooks would still work - but I think it will.

Yes Fishrrman - I did turn that on. Before I did that, it told me it couldn't boot because of the setting. I turned it off and it gave me the error that the disk couldn't be verified.

Let me update it and try again. I'll let you know - and sorry for the slow reply!

Again -- I reckon the version of the OS on the external drive is too old or otherwise incompatible to boot the NEW MBP 16".

If your new 13" MBP is a 2019 (sure wish I knew so I could quit guessing), then the SuperDuper! USB clone will need to be 10.14.6. The .6 is important information not included in your reply nor was the information about the new 13" MBP (year?). The minimum macOS for a 2019 13" MBP is 10.14.5 (and even then it is probably a special 10.14.5 OS to support the new model).
