CCC: Support for macOS High Sierra and APFS

Apple introduced macOS "High Sierra" this week, and along with many other developers, we've eagerly started dissecting the new operating system to see what's new. Like in past years, those living on the bleeding edge are wondering, "Will CCC work with this new OS?". Or perhaps "when" prepended to that same question. The short answer is that we have already posted a CCC v4 beta that offers preliminary support for High Sierra just a day after the new OS was announced.

CCC 4: Support for macOS Sierra

Update September 16: CCC 4.1.10 qualified on macOS Sierra

Choose "Check for Updates" from the Carbon Copy Cloner menu to download the latest update. And be sure to update your backup before upgrading to Sierra!

Protect yourself from ransomware with a Carbon Copy Cloner backup

Recently Palo Alto Networks reported a "ransomware" threat to Mac users named "KeRanger". After reading their analysis I found myself deeply concerned. Ransomware threats are nothing new, but I realized that this is probably the closest I've felt to the seedy world of cyber terrorism. Up until now all of that seemed to be aimed at governments, defense departments, big corporations... Windows users!

CCC is not affected by the recently-reported Sparkle vulnerability

A security vulnerability was recently reported on the Sparkle framework that many applications, including CCC, use to manage application updates. The report indicates that applications using non-secure (e.g. http rather than https) URLs to retrieve application update information could be vulnerable to a "man in the middle" attack.

Will I be able to use the current version of CCC on Apple's next OS upgrade?

We hear this concern frequently:

"I'm considering buying CCC, but I am concerned that a new OS will come out and I will be asked to purchase a new license to continue using CCC."

CCC updated for El Capitan

We released CCC 4.1.4 last week with a handful of minor bug fixes, as well as some enhancements and a stamp of approval for use with OS X 10.11 "El Capitan". This update is free for CCC 4 license holders, and recommended for anyone currently running CCC 4.

Status update: CCC beta testing on El Capitan beta

We posted a beta of CCC for El Capitan beta testers back in June and I'm happy to report that our testing of CCC 4.1.4 (beta) has been going well on the new OS. So far we haven't found any significant problems. We've made a couple adjustments to how the Recovery HD partition is cloned, but that change was relatively minor. Backups are bootable, scheduled tasks are running on schedule, smart updating is updating smartly, backups to network volumes are working great. On the whole, this appears to be a low-impact OS change.

Will CCC 4 work with the next major OS?

We're on the cusp of Apple's next Worldwide Developer Conference, and like many other developers, we've started to expect a new OS announcement during the Keynote. That inevitably raises the question, "Will CCC work with that new OS?"? The short answer is yes — by the time Apple ships that OS, we'll have CCC completely qualified and running on that OS. I posted a much longer explanation last year, however, that explains why the current version of CCC will not open on that new OS:

Will CCC work with [insert Apple's pre-release OS here]?

Another year has passed, and Apple has announced another operating system. Moments after the announcement, people started asking if CCC would "work" on the Developer Preview of the OS. The short answer is "No", but I think my fellow developers deserve a longer answer, and one that should address these questions for years to come as well.
