We have discouraged the use of thumb drives in the past due to performance and reliability issues related to making these devices bootable. Specific hard drive recommendations Mount issues render USB thumb drives unsuitable for bootable backups WD My Passport enclosures with a rotational HDD should be avoided. Please note that the WD My Passport SSD is NOT included among these reports. Due to the number of cases of confirmed failed bootability, however, we discourage users from purchasing new WD My Passport HDD enclosures if your intent is to create a bootable macOS Catalina backup. In other cases the system transparently boots to the internal disk, and in other cases (probably most) the enclosure boots fine. The results are inconsistent - in some cases the system proceeds approximately 75% into the startup process, then shuts down. In all cases the end user was able to confirm that the macOS Installer was also unable to make the device bootable. We have received several reports now of Western Digital My Passport hard drive enclosures failing to function as a startup disk with macOS Catalina. Emerging issue: Higher incident rate of macOS Catalina failure to boot from Western Digital My Passport enclosures We offer specific hard drive recommendations here. If you prefer to maintain bootable backups, you should purchase an enclosure that will be bootable with macOS Catalina. If you need to restore data from this backup, you can either place the external hard drive into a different hard drive enclosure, or you can migrate the data to a fresh installation of macOS Catalina via the Migration Assistant application. Workaround: If your external device does not have a USB interface, you can continue to make backups to that device, but they will not be bootable while that device is attached via Firewire.

Solution: If your external device also has a USB interface, attach the device to your Mac using a USB cable instead. The macOS Catalina Installer will explicitly disallow installation onto a FireWire-attached device, and if you attempt to boot macOS Catalina from a FireWire-attached device, the startup process will fail with the universal 'no entry' symbol.

macOS Catalina will not boot from a FireWire deviceĪpple has dropped support for booting from FireWire devices. We have reported this issue to Apple (FB7433465) and we are currently awaiting a response. 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 We also recommend disabling support for extended attributes (via the Advanced Settings). your home folder) directly to the NAS volume (i.e. Workaround B: If connecting to your NAS volume via AFP is not an option, then you can back up user data (e.g. Choose 'New disk image.' from CCC's Destination selector and specify a new disk image on the AFP-mounted NAS volume.Type in 'afp://' to connect to the NAS volume via AFP.Choose 'Connect to Server' from the Finder's Go menu.Eject the NAS volume if it's currently mounted.Workaround A: Several users are reporting that connecting to the network volume via AFP rather than SMB resolved the problem: Time Machine also uses sparse disk images on NAS volumes, so its requirements for the NAS file sharing service would be the same as those required for generic sparse disk image support. Solution: Several users have reported that adjusting the SMB configuration on the NAS to support Time Machine can resolve the problem. After months of investigation, we have concluded that macOS Catalina has more stringent requirements for sparse disk images than previous OSes. If you attempt to create the disk image in Disk Utility (for example), Disk Utility reports an 'RPC Error'. We have received several reports that macOS is unable to create disk images on SMB volumes hosted by various NAS devices.

Some SMB volumes can't support macOS sparse disk images We cite known problems that Apple introduced in the new OS below. CCC 5.1.10 (and all versions of CCC 6), published in August 2019, is fully compatible with macOS Catalina. Apple published macOS Catalina in September 2019.
