macOS High Sierra InstructionsIf you are deploying Parallels Desktop on macOS High Sierra (version 10.13), you will need to take additional steps before or after the deployment in order for Parallels Desktop to launch. macOS High Sierra requires user consent in order to load kernel extensions. This is known as User Approved Kernel Extension Loading. Parallels Desktop needs to load kernel extensions (drivers) in order to deliver core functions, such as hypervisor virtualization, shared and bridged networking, and USB connectivity in a virtual machine. macOS High Sierra will not load these extensions unless the Mac user approves them. When mass deploying Parallels Desktop, you have two options to approve Parallels Desktop kernel extensions on a Mac, which are described below. Note: Please note that if Parallels Desktop was already installed on a Mac at the time of upgrading to macOS High Sierra, its kernel extensions will be automatically approved and will not require any user action, so the steps described below are not necessary. Disable user approval requirement before the deployment You can disable the user approval requirement for Parallels Desktop kernel extensions (KEXTs) on a Mac computer before you deploy Parallels Desktop on it. This can be done either via booting into macOS Recovery or while preparing NetBoot/NetInstall/NetRestore images. The command to disable the approval requirement for Parallels Desktop KEXTs is as follows: spctl kext-consent add 4C6364ACXT After executing the command above, you can successfully deploy Parallels Desktop on this Mac. For more information, please see the following Apple Support article: https://support.apple.com/en-gb/HT208019 Alternatively, if you are using mobile device management (MDM) service, all systems with a valid MDM profile installed will not require user approval to load any properly-signed kernel extension. Approve Parallels Desktop extensions after the deployment You can also deploy Parallels Desktop first and approve its kernel extensions on a Mac computer after the deployment is complete. Note: You can only use the instructions described here if you are deploying Parallels Desktop version 13.2.0 or later. If you have an earlier version (e.g. 13.0.0 or 12.x.x) and want to deploy it on macOS High Sierra, you can only use the first option described above (i.e. using the To approve Parallels Desktop kernel extensions on a Mac:
Parallels Desktop will now start normally. Please note that this has to be done only once when you start Parallels Desktop for the first time. |
