Boot Camp will add a partition on-the-fly to your system drive, but there are some things that can stand in the way of that process. AppleInsider explains how to fix most of the issues preventing you from setting up that partition, if the assistant throws you the failure to partition error.


Pre-step. Get a backup with something other than Time Machine. For this task, we recommend Carbon Copy Cloner, SuperDuper, or ChronoSync to make a fully bootable, fully clone-able backup volume.
We've spoken about Carbon Copy Cloner and ChronoSync in the past. Before we go any further, it might be worth taking a look again.

Disable FileVault

FileVault can, in some cases interfere with the partitioning process. Why, we're not sure, but the best and least destructive, way around it is to turn off Filevault, if it is on. If it isn't, then go to the next step.
Select System Preferences, and click Security and Privacy.

Click on the FileVault tab. Unlock the pane, validate your credentials, and click Turn Off FileVault.

This isn't an immediate process. Decryption of your drive happens when the Mac is awake and plugged in. So, either use your Mac for a few hours doing things other than making a Boot Camp partition, or tell your Mac to never sleep in the Energy Saver control panel and walk away for a while.

Turn off Time Machine, un-associate any backup drives

You've got a backup, right? Don't proceed any further unless you have a backup that doesn't depend on Time Machine.
First, disassociate any backup drives with Time Machine. Select System Preferences, and click Time Machine.

Click Select Disk

Click on the drive being used as your Time Machine backup, and click Remove Disk. The Mac will pop up a dialog asking you to confirm that you want to do so.

Try to use Boot Camp assistant to partition the drive again. Should it still fail, you may need to remove Time Machine local snapshots as well.

Purge Time Machine local snapshots

For the tech saavy, the procedure to do this is different in High Sierra than it used to be. Apple killed a one-step, easy, Terminal process to turn off the feature, and automatically delete all local snapshots.
The procedure is still in the Terminal, though. Open the Terminal.

Enter tmutil thinlocalsnapshots / 9999999999999999
Depending on how many you have, and the speed of your drive, it may take a few moments to eradicate all the snapshots.

The above steps deal with most of the obstacles to a successful Boot Camp Assistant partitioning of your system drive. Once more, try to use Boot Camp Assistant to make the partition.
If all that still doesn't allow the partition to be created, then...

Format your hard drive

If you've gotten this far, we're pretty confident of your ability to do this step. First, make sure you have a backup! Reformat your drive either by booting from your restore clone, or rebooting in recovery mode, and set up an APFS partition for your macOS install, and a macOS Extended (journaled) partition for what will become your Boot Camp partition later in the process.
Restore your backup to the APFS partition, run the Boot Camp Assistant again, and all should be well.

Boot Camp Assistant User Guide

Newer Mac computers use a streamlined method to install Windows on your Mac. To find out whether your Mac uses this method, see the Apple Support article Install Windows 10 on your Mac with Boot Camp Assistant. If your Mac is an older model, follow the instructions in Install Windows on your older Mac using Boot Camp instead.

What you need

• The keyboard and mouse or trackpad that came with your Mac. If they aren’t available, use a USB keyboard and mouse.

• A full-installation, 64-bit version of Windows 10 on a disk image (ISO file) or other installation media.

  You can download a Windows 10 Disc Image (ISO File) from Microsoft.

• Sufficient free storage space on your startup drive. For information about the amount of free space needed, see the Apple Support Article Install Windows 10 on your Mac with Boot Camp Assistant.

Before you begin

Before you install Windows, make sure you back up important files.

You can use Time Machine or any other method to back up your files. For information about backing up files, see Back up your files with Time Machine and Ways to back up or protect your files.

Perform the installation

On your Mac, do the following steps in order.

Step 1: Check for software updates

Before you install Windows, install all macOS updates.

1. On your Mac, log in as an administrator, quit all open apps, then log out any other users.

2. Choose Apple menu > System Preferences, click Software Update, then install all available macOS updates.

   If your Mac restarts after installing an update, open Software Update again to install any additional updates.

Step 2: Prepare your Mac for Windows

Boot Camp Assistant prepares your Mac by creating a new partition for Windows named BOOTCAMP and downloading the Boot Camp support software.

Important: If you’re using a portable Mac, connect it to a power source before continuing.

1. On your Mac, open Boot Camp Assistant , located in /Applications/Utilities.

2. At the Introduction screen, click Continue.

   The system is checked for total available disk space. Older Time Machine snapshots and cached iCloud files are removed to make space for Boot Camp. This process may take a long time to complete (you can click the Stop button to skip this process).

3. At the Install Windows step, click Choose, then select the Windows ISO image.

4. Specify a partition size by dragging the divider between the macOS and Windows partitions.

5. Click Install.

When this step is complete, the Windows installer starts.

Step 3: Install Windows

1. In the Windows installer, follow the onscreen instructions.

   When the installation is finished, your Mac automatically restarts using Windows.

2. Follow the onscreen instructions to set up Windows.

Step 4: Install Boot Camp on Windows

Mac Os High Sierra Apfs Boot Camp

After installing Windows, Boot Camp drivers that support your Mac hardware start installing.

Note: If the support software doesn’t install automatically, you need to install it manually. For instructions, see the Apple Support article If the Boot Camp installer doesn't open after using Boot Camp Assistant.

1. In the Boot Camp installer in Windows, follow the onscreen instructions.

   Important: Do not click the Cancel button in any of the installer dialogs.

   If a message appears that says the software you’re installing has not passed Windows Logo testing, click Continue Anyway.

   You don’t need to respond to installer dialogs that appear only briefly during installation, but if a dialog asks you to install device software, click Install.

   If nothing appears to be happening, there may be a hidden window that you must respond to. Look behind open windows.

2. When the installation is complete, click Finish.

3. After your Mac restarts, follow the instructions for any other installers that appear.
