This problem does not appear to be specific to any particular enclosure, rather it appears to be specific to the 2012 models of Mac mini and MacBook Pro. This issue is not specific to CCC, we have confirmation that this occurs when installing Catalina directly onto an external device as well.

We have received several reports that the 2012 Mac mini and the 2012 MacBook Pro can initially boot from a non-encrypted external USB device, but then will fail to boot from that device when FileVault is enabled on the external device. 2012-vintage Macs can't boot macOS Catalina from an encrypted USB device If your Mac does not have a Firewire port, but has Thunderbolt ports, you can use the Apple Thunderbolt to Firewire adapter. Possible workaround: If your external device has a Firewire interface, and your Mac is running an OS that is older than Catalina, then you can attach the device to your Mac via Firewire and boot from any size of volume. Note that when partitioning a disk in Disk Utility, the top of the pie chart is the beginning of the disk in other words, the first partition starts at 'noon'.

If you have an older Mac and you're having trouble booting it from a USB device that is larger than 2TB, try creating a 2TB partition at the beginning of the disk and make your backup to that partition. Some Macs, especially those produced prior to 2014, cannot 'see' the content of a volume that lies past the 2TB mark on the disk at boot. Some Macs may not boot from USB devices larger than 2TB If CCC's Task Plan didn't report any configuration concerns for your backup volume and you are having trouble booting from it, try the Firmware Discoverability Troubleshooting steps below. Ordinarily, a CCC bootable backup volume will appear in this list, but occasionally your Mac's firmware may have difficulty discovering the hardware that hosts your backup.

Using only device drivers that are stored on your Mac's firmware chip, the firmware will scan all of your SATA, PCI, USB, and Thunderbolt busses for hard drive devices, then read those hard drive volume headers to determine if a macOS system is available on each volume. When you boot your Mac while holding down the Option key (Intel Macs) or the Power button (Apple Silicon Macs), the Mac Startup Manager will display a list of available startup devices. Sometimes the Mac's firmware cannot detect your backup device Creating legacy bootable copies of macOS Big Sur.Some Big Sur startup volumes don’t appear in the Startup Disk Preference Pane.Our support for system copying and bootability on Big Sur and later OSes is limited to the suggestions noted above. If that does not produce a bootable device, then the device is not suitable for functioning as a bootable device on your Mac.

If that does not produce a bootable volume, and if you have exhausted the Firmware Discoverability Troubleshooting steps below, then we recommend that you install macOS onto the backup. When you configure a CCC backup task using the Legacy Bootable Copy Assistant, CCC will automatically use Apple's proprietary APFS replication utility (ASR) to make a block-for-block exact copy of the source. This volume is cryptographically sealed, and that seal can only be applied by Apple ordinary copies of the System volume are non-bootable without Apple's seal. Starting in macOS Big Sur, the system now resides on a 'Signed System Volume'.

Can I restore my Mac's backup to another computer?.

If you're trying to migrate content to a new Mac, use Migration Assistant for that purpose - do not attempt to restore an older Mac's backup onto a new Mac. No Mac will ever boot from an OS that is older than what it shipped withĪpple has never supported booting a new Mac from an OS that is older than what it shipped with. Only Apple can make an external device bootable with macOS Big Sur, however, so our support for external boot on Big Sur and later OSes is limited to the suggestions offered below. We're happy to help you troubleshoot bootability problems affecting macOS Catalina.
