The TeamViewer remote connectivity cloud platform enables secure remote access to any device.

Use with a Mac requires a software download. Related DocumentationSanDisk SecureAccess software is supported by Windows XP, Windows Vista, Windows 7, Windows 8, and Mac OS 10.5 and up.Some Big Sur startup volumes don’t appear in the Startup Disk Preference Pane 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 make a backup of a Big Sur startup disk with CCC 5.1.23 or later, CCC will automatically use Apple's proprietary APFS replication utility (ASR) to make an 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.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".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. 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 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. 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. 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. Ie with silverlight for macChange the External Boot (or "Allowed Boot Media") setting to Allow booting from external mediaPlease do not, however, change the Secure Boot setting for the purpose of booting from a backup.

You can update now or select another startup disk.Spoiler alert: The "Update" option does not work. Booting 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. Good android emulator for xamarin on macAlso, 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. Macs with "up-to-date software" don’t automatically load Option ROM firmware, so your Mac won't see devices that have Option ROM firmware until you load that firmware. Make the Startup Manager load additional driversSome third-party external devices use Option ROM firmware. 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) 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. Detach, then reattach the backup volume's USB or Thunderbolt cable from/to your Mac and wait up to another 30 seconds.
