So true!
That's the best advice one could give about a new OS, especially when it comes with a new FS!
I'll most probably be waiting for 10.14 before I switch to 10.13...
Unless I buy a new mac which would not let me that choice.

I'll have more on this as soon as I get the blog post I'm working on done...

The blog post is up now... and, v2.9.2 is out as well.

Update appreciated and installed, but...
The error message is still the same as before: SuperDuper! cannot find source volume "Macintosh HD".

Am I doing something wrong? (I restarted the iMac, but no change.)

Is it APFS? Sounds like it is, and if you read the post at, you'll see we don't yet support APFS, along with some discussion.

Sorry, I hadn't (yet) seen the blog post -- just thought v2.9.2 might do APFS, which was done automatically as part of the High Sierra beta.

New blog post at with a beta of v3.0, with APFS support...

HFS+ Cloning with High Sierra
Dave, both my internal drive and external drive (USB 3 connected) are HFS+ volumes. My internal is now updated to High Sierra, and works well. Am I able to run a bootable backup clone to the external Sierra drive, or do I need to boot into the external, install High Sierra there, and then, boot back into the internal and run the normal SD cloning to end up with the bootable external?

Just wanting to take the minimum steps.

dnanian 09-26-2017 08:33 AM

No, you can copy to it from High Sierra (HFS+->HFS+).

So, I will back up from internal High Sierra to external Sierra, and when done the external will be updated to bootable High Sierra. If so, I am good.

dnanian 09-26-2017 02:42 PM

Yes, you can do that.

I have just downloaded the 3.0b1, and finally was able to register it (bought superduper I dunno how many years ago).

However I had not yet used superduper at all on many iterations of the High Sierra betas and GM candidate. When I launched the 3.0b1 (sure wish I didn't have to use the usual to open it, e.g. control-cmd open) and tried to register using the Register menu item, there was no place for the name and serial number.

After relaunching a couple of times with no success, I downloaded the 2.9.2 version, registered that and then the registration showed up in the 3.0b1.

I dunno, but I think this might be a bug to fix.

best regards,
Philip Noguchi:):)

That's weird - I just opened, and selected "Register..." and my window opened fully and showed my serial and name + the buttons. Does it still reproduce for you?

High Sierra backup
iMac Retina 5K, 27" Late 2014

I installed High Sierra on my internal drive, which is SSD, so the installation automatically changed it to APFS. I installed SuperDuper 3.0 B1 and tried cloning to an external USB3 drive and an external SSD, both HFS+. Smart copy would not work. Erase and then copy did work, but SuperDuper could not make either drive bootable.

But the process did convert the external drives to APFS.

To make the external SSD bootable, I installed High Sierra on it and that worked, retaining the cloned files. Too hard for routine backup though.

Is this what you expected from 3.0 B1?

dnanian 09-26-2017 09:33 PM

We know of a problem copying APFS->HFS+ (it tries to bless Preboot and fails), but if you just format as APFS it should copy with Smart Update and boot fine. It does here...
