In a pie chart, the arc length of each sector and consequently its central angle and area, is proportional to the quantity it represents.

Some Macs may not boot from USB devices larger than 2TBSome 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. 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.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. 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. Cloning macOS System volumes with Apple Software RestoreSometimes the Mac's firmware cannot detect your backup deviceWhen you boot your Mac while holding down the Option key, the Mac Startup Manager will display a list of available startup devices. Some Big Sur startup volumes don’t appear in the Startup Disk Preference Pane 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. 2012-vintage Macs can't boot macOS Catalina from an encrypted USB deviceWe 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. If your Mac does not have a Firewire port, but has Thunderbolt ports, you can use the Apple Thunderbolt to Firewire adapter. How much for mac os sierraA 2018 MacBook Pro or an iMac Pro) from your CCC bootable backup, be sure to change your Mac's External Boot policy to allow booting from an external hard drive. Enable "External Boot" on T2 Macs (this is not required on M1 Macs)If you are attempting to boot a Mac with an Apple T2 controller chip (e.g. Some people have found that cloning Mojave to a RAID array can work, however this is not a supported configuration, and does not appear to be a viable option for macOS Catalina. Apple no longer supports booting Macs from RAID devicesStarting in macOS Mojave, Apple no longer supports installing macOS onto a RAID device. Click the Enter macOS Password button, then choose an administrator account and enter its password. Choose Startup Security Utility from the Utilities menu in the menu bar ( see this screenshot for clarification) Restart your Mac while holding down Command(⌘) and the "R" keys. Be sure to select a language that matches your keyboard, otherwise the Startup Security Utility may not accept your password. Do note the exception to this when attempting to boot one of these Macs from a different Mac's backup.Note for users with non-QWERTY keyboards: When you initially boot into Recovery mode, you'll be prompted to select a language. "Full Security" is the default setting, and that setting is compatible with booting a T2 from its own backup. Find Pie Chart For Hard Drive Use On 2018 Update Is RequiredBooting from an external volume works fine in general, but if your external disk is formatted using Apple's legacy HFS+, "Mac OS Extended" format, enabling FileVault on that volume will render it non-bootable, producing an error message like this on startup:A software update is required to use this startup disk. When a firmware password is applied, your Mac will require a password to load the Startup Manager on startup.Apple Kbase HT204455: How to set a firmware password on your Mac T2-based Macs can't boot from encrypted HFS+ volumesOur testing has confirmed that Macs with Apple's T2 controller chip cannot boot from an encrypted, "Mac OS Extended"-formatted, external volume. Because the primary purpose of a CCC bootable backup is to function as a rescue disk in the event that your Mac's startup disk fails or otherwise becomes non-functional, we recommend leaving your Mac configured to allow booting from external devices.For additional startup security, you can apply a firmware password. If your Mac's startup disk were to fail, it would be impossible to change the startup security settings. Changing settings in the Startup Security Utility requires a functional user account on the internal disk of your Mac. Make the Startup Manager load additional driversSome third-party external devices use Option ROM firmware. In either case, if you want to encrypt your external, bootable backup of a T2-based Mac, we recommend formatting that backup volume as APFS. This may be a bug in the firmware of the T2 Macs, or it may be a limitation that Apple does not intend to address. Also, for good measure, use Disk Utility's "First Aid" utility to verify and repair any filesystem problems that may be present on the destination volume. Here's a partial list of devices we've received reports of that use Option ROM firmware:Rule out generally incompatible configurations and filesystem anomaliesIf you are using an external hard drive enclosure or adapter, see whether your enclosure is listed at the bottom of this page as an enclosure that we've seen problems with in the past. Press Option-Shift-Command-Period at the Startup Manager window to load Option ROM firmware from any currently-attached hard drive enclosures. Press Option-Shift-Command-Period at the Startup Manager window to load any Option ROM firmware that is present and required for an external hard drive enclosure. If your backup volume appears at this step and the boot process proceeds past the Apple logo, skip to the section below. Wait about 30 seconds to see if the backup volume appears. Start up your Mac while holding down the Option key. Attach the backup disk directly to a USB or Thunderbolt port on your Mac ( no hubs, no adapters, no monitor ports, no daisy chaining, no third-party USB cards) Detach all peripherals from your Mac except for the keyboard and mouse (including any secondary displays) Then start it up holding down the Option key, waiting another 30 seconds for the volume to appear. If the backup volume still does not appear as an option, shut down your Mac completely. If your backup volume appears, select it and proceed with the startup process.
