Sequoia 15.2 and Carbon copy cloner

Thanks, @ALWeir!

Have you run a CCC clone which definitely included 'either the Preboot or Recovery'?

I remember SuperDuper! originally had difficulties cloning Apple's new architecture, while CCC did it immediately.

I'm nervous about upgrading from 15.1.1. to 15.2 if there's any chance that a CCC clone would fail.

Thank you, @tbirdvet - seems promising, doesn't it.

When you installed Sequoia, was that 15.2 from an earlier version of Sequoia, or from macOS 14 or earlier?

I still have an Intel iMac… waiting for M4's (next year, now, presumably).

From that post by Shirt Pocket, do you think I'd be unlikely to need or miss the partitions that are failing for SuperDuper! on 15.2?

Could I just run CCC per this page?

It's the fact that SuperDuper! seems to abort no matter what that worries me.

Thanks very much, @PRP_53. That's re-assuring, isn't it.

Also that Mike seems to have added that paragraph in red at the top 11 days ago - presumably when he might have been testing 15.2 beta.

Since I want to 'follow the rules' and not try to create legacy boot clones, the more I read from posters here (thanks, everyone!) the safer I feel :-)

Great. Thanks, Steve!

I'm now 99% sure that I can safely upgrade from 15.1.1 to 15.2. Shall wait to hear from Mike, I hope tomorrow.

But as a by-product of all the information posters have kindly offered here, I obviously need to adjust my expectations for bootable clones (to not doing them).

I've obviously lived with CCC doing what it does so well for years now. But to read Dave's description of SuperDuper! aborting was disturbing.

Again, appreciated…

Thanks, Matti!

(Like many here, I'm sure, I'm fanatical about keeping my Macs tidy and - hopefully - every likely to be compromised.)

Hence my extra hesitation. Your re-assuring reply much appreciated.

@PRP_53,

The futility (if that's not too strong a word) of trying to make a bootable clone on either Intel (which I still have: am waiting for an M3/M4 desktop… in 2025 now) or Silicon machine (soon :-) ) is one of the things I have learnt here; thank you!

My real concern, I guess, was that CCC 7.0.4 would simply not complete under 15.2 (and so I'd have no usable non-bootable clone) - in the way that SuperDuper! seems not to complete under certain circumstances. Dave writes (emphasis (bold) mine):

Apple broke the replicator. Towards the end of replicating the Data volume, seemingly when it's about to copy either Preboot or Recovery, it fails with a Resource Busy error.

I have probably been being over-cautious!

I have an inquiry in with Mike at Bombrich; Yes.

I've looked elsewhere - in all the usual places - including on their site… no mention of anything with CCC - yet :-) ?

Thanks.

Thanks very much, @den.thed!

If an older version than the latest of CCC works, then there are surely very good chances that v.7 will.

Much appreciated… most encouraging :-)

Thanks, @Old Toad!

That's good news.

I have a funny feeling I can stop being concerned now and - perhaps subject to what Mike says on Monday - just upgrade and expect to be able to clone.

Thanks again, @tbirdvet!

I now think I shall have no problems. I agree: Legacy boot is not crucial (or always reliable). For CCC to complete the clone is parity with what I have now.

Appreciated… :-)
