We're on the eve of World Backup Day – March 31st (because you're an April Fool if you didn't back up on March 31), so now is a great time to revisit some Backup Best Practices. If you're already using CCC for your backups, you've got a great leg up! If you haven't given it a whirl yet, today is a great day to try it out.

We've had so many new features in the oven for a while, and now we're finally ready to share it with the world! CCC 6 offers unprecedented accountability for your backups and insight into what's changing on your Mac, plus a brand new file copier that's faster, smarter, and designed to adapt to Apple's fast pace of OS and filesystem innovation.

Take a look at what's new in CCC 6:

CCC 5.1.27 and CCC 6 can make bootable copies of the system on Intel and Apple Silicon Macs (11.3+) right now, and we'll continue to support that functionality as long as macOS supports it.

CCC 5.1.23+ can make bootable backups of Big Sur on Intel and Apple Silicon Macs.

Update May 13, 2021: CCC 5.1.27 can now make bootable backups of a Big Sur startup disk on all Macs.

We posted our Catalina-certified build of CCC way back in August, so the last few weeks have been eerily calm. Now that Apple has made the OS release schedule so consistent, we find this time of year to be a lot less stressful by simply being ready for it, on time. Since about Catalina Beta 9, the OS has been feeling pretty polished and ready for prime time. I think I have just one gripe with Catalina — Spotlight is so persistently annoying when it prevents volume unmount requests!

In a delightfully predictable manner, Apple announced last Wednesday that macOS Mojave will be available on the Mac App Store on September 24. From the moment that Apple introduced Mojave to developers in June, we've been putting it through its paces to see what we can expect when Mac users apply the upgrade this Fall, and to get CCC 5 qualified on this new OS. We're happy to announce that CCC 5.1.5, available today, is fully qualified on macOS Mojave.

On the eve of World Backup Day and with stories like the Atlanta ransomware attack still in the news, now is a great time to revisit your backup strategy. It's also a great time for us to announce some great new features that we're getting ready to deliver as a free update to CCC 5 users – features that will help you improve your defenses against ransomware and malware.

Well, I did it. I know that I've told many people I'd be waiting until Thanksgiving to apply the High Sierra upgrade to my own production machine, but after some reflection this week, I decided that High Sierra was ready for me, and that I was ready for High Sierra. I've always been decidedly anti-upgrade when it comes to my own production system. Upgrades tend to break things, and I just can't afford downtime on my laptop. High Sierra and the APFS transition, to me, was a potential double-whammy for breaking things, so I was bearish on this upgrade in particular.

The time for betas is over! High Sierra is here. APFS is here. We're ready for both, and we've got you covered. APFS, HFS, encrypted, not encrypted, FileVault – whatever your source or destination, we support all of these combinations in CCC 5. We've tested so many different scenarios, we put the results into a chart to keep track of them.
