The important thing to do is make the backup before you upgrade, and understand your downgrade options before proceeding with the upgrade. Having a bootable backup gives you an additional recovery option, but you can downgrade your Mac from a CCC backup whether that backup is bootable or not. Until you are ready to commit to the newer OS, you don't want the backup disk to be upgraded automatically by a scheduled backup task.Дowngrading from a bootable backup requires fewer steps, but the reliability of Apple's External Boot solution has waned in the past several years.

Detach your backup disk from your Mac and set it aside.

Intel Mac running Big Sur+ (optional)вЂ : Click on the Destination selector and choose 'Legacy Bootable Backup Assistant', then click the button to allow CCC to erase the destination.

Choose your backup volume in the Destination selector.

Choose your startup disk in the Source selector.

Prepare your backup volume for the backup.

If you would like a recommendation, we offer some here in CCC's documentation. Early adopters inevitably find some shortcomings and bugs which are resolved in minor OS updates. The early releases are exciting, but that excitement involves risk. Lastly, we recommend that any users that rely heavily upon the availability of their Mac for work or other productivity consider waiting for several OS updates before making a major upgrade. These sorts of procedures require time and effort, though, so you should weigh that potential hassle against the potential gain of the OS upgrade.

What software will no longer work after applying the upgrade?.Does the upgrade fix a problem that is preventing me from effectively using my Mac?.Will this upgrade improve the performance of my Mac, or degrade performance?.Does the upgrade offer any compelling features?.Major system upgrades are often disruptive, so we have always recommended a very conservative approach to applying them. Unless, that is, you have a CCC backup of your Mac made before you upgrade. If you upgrade your OS only to discover that a critical third-party application or peripheral doesn't work right, you could be really lost when you discover that it's impossible to downgrade to a previous OS. So Apple has shipped the next major operating system, and you're excited to upgrade! But are you ready? OS upgrades offer the thrill of new features, better performance and bug fixes, but they can come at a price - your time and potentially your productivity.
