Carbon Copy Cloner For Windows
I have a 13' 2017 macbook pro, running High Sierra. I'm trying to boot a cloned Snow Leopard OS (Carbon Copy Cloner backup) from an external drive, but keep getting the 'Prohibited' / 'No Access' icon (see attached image) after I choose the drive in Startup Manager. I've tried this. Both APFS and HFS are valid destination formats when using Carbon Copy Cloner 5 on High Sierra and Mojave. When making a backup of a macOS Catalina system volume, CCC will automatically convert the destination volume from HFS+ to APFS, but only after your explicit approval of the action.
CCC 5: Support for macOS 11 Big Sur
CCC 5.1.22 (and later) is qualified for macOS 11 Big Sur. Open CCC and choose 'Check for updates...' from the Carbon Copy Cloner to get the update, or click the 'Download CCC 5' button above. Please take a moment to review the following resources prior to upgrading to macOS Big Sur:
Carbon Copy Cloner 4.1.24 is compatible with Mountain Lion (10.8), Mavericks (10.9), Yosemite (10.10), El Capitan(10.11), Sierra (10.12) and High Sierra (10.13). Note that while this version of CCC may work on El Capitan and newer OSes, we recommend that El Capitan+ users upgrade to CCC 5. We offer technical support for CCC 4, but we are no longer actively developing it. If you are having trouble downloading CCC from the link above, try this alternate download location.
CCC 4 and Mojave+: CCC 4 is qualified up to macOS High Sierra. CCC 4 license holders are welcome to continue using CCC 4 on later OSes with the understanding that this is an untested and unsupported configuration. CCC 5 is fully qualified on macOS Mojave and offers extensive support for APFS, including support for point-in-time restores via APFS filesystem snapshots.
