Raising the Bar on Security and Privacy

Last Friday, Apple announced plans to improve how requests to grant Full Disk Access are made. Initially I was a bit wary about how that might affect the CCC installation workflow; I still remember the challenge of coaching users through the initial rollout of privacy controls in macOS Mojave. After having some time to digest Apple's words, I'm now enthusiastic about changes to the procedure of granting Full Disk Access – primarily as a user, but also as a developer. Asking the user to grant Full Disk Access to CCC is a huge responsibility. That's a responsibility that we take very seriously, and it's something that I think some companies have been far too casual about. Apps or businesses that have an economic interest in your private data should never "need" Full Disk Access.

Apple's announcement seems likely to be related to the rise of AI agents, and recent reports of agents gaining access to private user data, and other malfeasances. If you're not familiar with AI agents, these are AI models that go beyond answering questions in a web browser; they live on your Mac and can do real things on your Mac at your behest....

Bootable backups have been deprecated for several years

Update Sept. 10, 2026:

Well, it's almost 2 years later and we are pleasantly surprised to see that Apple hasn't completely sunken support for bootable copies. Apple's solution hasn't been drama-free, but we keep finding workarounds to make it work. We'll continue to support that functionality as long as we can keep it working.

With all that said, Apple hasn't revised its stance that this capability could be dropped or broken in any future update. So, if you have an Apple Silicon Mac, we recommend that you treat bootable backups as a redundancy strategy. Take advantage of it while it's around, but don't put all your your eggs in that basket.

While some developers seem surprised by a change in macOS 15.2, we've known for several years that making bootable backups would eventually become impossible. We shifted CCC's strategy away from relying on External Boot so our users wouldn't be affected by this inevitable result.


I took a few days off last week to help a family member, and returned to find the Mac community all aflutter with comments about bootable backups not working after the 15.2...
