Press the icon in top left of screen Click RestartWe're happy to help you troubleshoot your bootability problems. The first step in our USB port troubleshooting is the easiest one: a simple reset of the Mac. And just like those applications, a reboot or a reset can fix a problem like a USB port. Sometimes, just like applications can act unresponsive and buggy, hardware ports can have similar problems.To identify the USB device in a Mac operating system: Open the apple manager: Click the Apple icon, then About This Mac.

Apple Kbase #HT2186: Don't install older versions of Mac OS than what comes with your computer In this 2-part series, we'll take a look at how to check your Can I back up one computer and use the clone to restore another computer?Your computer consists of both hardware and software and a number of things can go wrong. 1) Click the Apple icon in the upper right-hand corner and then click System Preferences. 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. 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. If your Mac does not have a Firewire port, but has Thunderbolt ports, you can use the Apple Thunderbolt to Firewire adapter. 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. If you require an encrypted backup, we recommend that you erase your destination as APFS or HFS+ encrypted, then create a data-only backup to that volume.We reported this issue to Apple (FB7433465) in November 2019 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. Physics body editor for macA 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. "Full Security" is the default setting, and that setting is compatible with booting a T2 from its own backup. Change 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. 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. 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. Can I leave this setting unchanged and change it only in the future when I actually need to boot from my backup?Generally no. Be sure to select a language that matches your keyboard, otherwise the Startup Security Utility may not accept your password. ![]() ![]() 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) 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.
