On Saturday, I'll be heading up to New Boston, NH to participate in the first group ride I've done in, well, years.

I'm both looking forward to it and dreading it, because like a lot of others I'm pandemic portly, out of shape, and out of practice.

But the only way to get out of that particular rut is to start riding in some other, muddier ones...so we'll see how that goes.

What better time, then, to release SuperDuper! v3.5 B3?

This new beta is another relatively minor update that polishes the experience a bit, deals with some common situations better, and fixes a few bugs.

  1. Under Big Sur and later, When you copy from a source volume group to a destination with Smart Update, we don't convert the result into a volume group with only a Data volume. This ensures the result is readily visible in Finder.

  2. We've added additional information to the What's Going to Happen? section to clarify, well, what's going to happen in your particular situation (and to suggest changes if needed).

  3. We've fixed a rare situation where, with certain disk configurations, the copy would fail before getting started with a "Can't obtain volume capacity" exception.

  4. An old error about metadata copying failures actually said it was copying "HFS+ metadata", but it could also be APFS metadata, so now it's just...metadata. Yes, we regressed this one carefully, to ensure it didn't start saying "exFAT" or "5.25-inch floppy disk", not to mention "disk pack".


One thing we've definitely noticed is that Apple silicon systems tend to sleep even when many individual processes are saying, quite explicitly, that they should not.

For example, on a scheduled copy, our schedule driver, interface and copy process all hold assertions that are supposed to prevent sleep. asr, when used, holds one itself. And yet, for some reason...

So, if you're seeing "Resource busy" errors after about, say, 10 minutes of copying, and you weren't actively using the system at the time, try setting the screen so that it "never" sleeps...

So, see? Not much to say, because the beta has been working well, other than to ask you to

Have at it, and thanks, as always!
