Windows 10 Boot Camp USB boots but throws 0xc0000225 before being able to install anything 1 How to install Windows 10 into a 2013 MacBook Air with or without using the Boot Camp Assistant? Follow these steps for a crappy work around. Disconnect the egpu (By the thunderbolt plug, not the power switch). Start up the mac and wait a few minutes for windows to boot (USB devices with light should light up once as the mac boots, then turn off, then light up again as windows boots). Set up the mac to boot into windows by default.

tl;dr:

  1. Download and extract the Apple Boot Camp drivers I repackaged: BootCamp-061-51481.zip
  2. Right-click BootCamp/Drivers/Apple/AppleKeyboardMagic2/Keymagic2.inf (or BootCamp/Drivers/Apple/AppleKeyboard/Keymagic64.inf or appropriate driver) and then 'Install'.
  3. Unplug and re-plugin your keyboard.
  4. If you want to reverse the fn key behavior, change HKEY_LOCAL_MACHINESYSTEMControlSet001ServicesKeyMagicOSXFnBehavior and HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesKeyMagicOSXFnBehavior from 01 to 00. Restart for registry changes to take effect.

If those drivers don't work, try getting latest from the source:

  1. Download latest exe from Brigadier release page.
  2. Find the latest or a current Mac model (ex: MacBookPro16,3).
  3. Run brigadier.exe -m MacBookPro16,3 to download Apple Boot Camp drivers.

If you can't or don't want to use Brigadier, see the bottom of this post.

Note: I have not tested this over Bluetooth. I keep my keyboard connected via the supplied lightning to USB cable.

I recently acquired an Apple Magic Keyboard and wanted to use it on my PC. It worked when I plugged it in but I could not access any of the media keys/fn keys (ex: volume up and down). This is because Windows was using the default keyboard drivers.

When I first started looking for solutions I found hacky, unsigned drivers and key mappers. These were not ideal.

Keymagic.sys Error Boot Camp Error Code

Apple actually does supply Windows drivers for Apple Keyboards, Apple Magic Keyboards, and apparently other Apple Mouse and Trackpad devices. Apple created these for Boot Camp (a program that allows you to run Windows in a virtual machine in OSX). However, there is not an easy way to access them. Normally, Apple wants you to download and install a large suite of software and drivers meant for Boot Camp which will do all kinds of nasty things to your PC. Thankfully, the keyboard and other drivers can be isolated and installed independently.

Download Boot Camp Drivers

If you want to skip this section, you can download the drivers I extracted from the bellow process and see if they work for you: BootCamp-061-51481.zip

Error

Because we are not going through Boot Camp, the first challenge is getting access to the Boot Camp drivers. The easiest way to do so is to use the Brigadier program. This automatically locates the URL for a given Mac model and downloads and extracts the appropriate Boot Camp drivers. If you can't or don't want to use this program, see the bottom of this post.

Download the latest exe from the releases page and run it like so:

Boot

MacBookPro16,3 is the model of the latest MacBook Pro (at the time of writing) which I got from this page. I used this model because I wanted to ensure I got the latest drivers.

This will create a folder next to brigadier.exe named something like BootCamp-061-51481. The numbers in the name will be whatever version of Boot Camp drivers were downloaded.

Install Drivers

Navigate to BootCampDriversAppleAppleKeyboardMagic2 for Apple Magic Keyboard drivers. I have not tested this, but I assume you would use BootCampDriversAppleAppleKeyboard for other Apple Keyboards. Or, $WinPEDriver$AppleMultiTouchTrackPadPro for Apple Magic Trackpad 2, etc. I don't think there is any harm in installing more drivers than you need as only the appropriate ones will be used, but that is also untested.

Right-click Keymagic2.inf (or whichever .inf file exists for your driver) and then 'Install' to install the driver.

After installation is complete, unplug and re-plugin your keyboard. If everything worked, you should be able to use the Volume Up/F12 (without holding the fn key) and the Volume will change. To debug, check in device manager; 'Apple Keyboard' should be listed under 'Human Interface Devices'.

Change fn Key Behavior

By default, when the fn key is not held, the media keys will be activated. When the fn keys is held the F1-12 keys will be activated.

To reverse the fn key behavior, open RegEdit and navigate to HKEY_LOCAL_MACHINESYSTEMControlSet001ServicesKeyMagic and update OSXFnBehavior key from 01 to 00 (in the binary editor this will update from 00000000 01 . to 00000000 00 .).

Not sure if this is necessary, but also navigate to HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesKeyMagic and make sure the OSXFnBehavior key has the same value.

Restart your PC for the registry changes to take effect.

Extra Drivers

Poking around in the Boot Camp package, I noticed several other drivers of note. BootCampDriversAppleAppleKeyboardInternalUSB may be related to the USB ports on Apple keyboards. There are also some drivers that looked to be related to Apple Mice, Trackpads, Cameras, Displays, etc:

  • BootCampDriversAppleAppleCamera
  • BootCampDriversAppleAppleKeyboard
  • BootCampDriversAppleAppleKeyboardInternalUSB
  • BootCampDriversAppleAppleKeyboardMagic2
  • BootCampDriversAppleAppleKeyManager
  • $WinPEDriver$AppleMultiTouchTrackPad
  • $WinPEDriver$AppleMultiTouchTrackPadPro
  • $WinPEDriver$AppleWirelessMouse
  • $WinPEDriver$AppleWirelessTrackpad

This is not a full list of drivers. Just the ones I found interesting. I have not tested any of these. Again. I don't think there is any harm in installing more drivers than you need as only the appropriate ones will be used, but that is also untested.

Brigadier Alternative

If you can't or don't want to use Brigadier, you can manually find, download, and extract the Boot Camp drivers. Brigadier uses this XML file (at the time of writing, subject to change) to locate the correct package. You can do this manually by downloading the XML file, opening it with a text editor, and searching for the BootCampESD.pkg URL with the latest PostDate. Downlad the .pkg file and extract the contents using 7-Zip, WinZip, WinRAR, or any other utility capable of unpacking .pkg and .dmg files:

  1. Extract Payload~ from BootCampESD.pkg
  2. Extract .LibraryApplication SupportBootCampWindowsSupport.dmg from Payload~ (this file is actually an archive).
  3. Extract the contents of WindowsSupport.dmg

Here are the 7-Zip commands used to accomplish the above:

Apple releases major Mac operating system updates annually, while minor system updates happen every two or three months. A new Mac OS is designed to improve user experience. However, many mac users found that a macOS update made their Mac not boot up. It could be really annoying when you urgently run your Mac, be it an iMac or a MacBook. This post will provide you with three steps. When your Mac doesn’t boot up, let’s keep on reading.

Solutions to fix Mac not turning on after macOS update

Let’s go straight to the point; you are suggested to troubleshoot this issue by the following steps:

  1. Check if the Mac hard drive is corrupted.
  2. Check if any program is not compatible with your macOS
  3. Check for a hardware incompatibility.

Now you can take a look at each of the steps.

Step 1: Boot into macOS Recovery mode to check the Mac hard drive

If your Mac has problems booting up after the macOS update, it’s possible your Mac computer ran out of power, and the APFS reformatting process was interrupted, or the startup disk was corrupted. To rescue it, you are advised to check and repair the disk with Apple’s built-in disk repair tool, Disk Utility, under macOS recovery mode. Grab your attention to see how it works.

  1. Hold Command + R and start your Mac into macOS Recovery mode.
  2. Select Disk Utility from the macOS ‘Utilities’ window and click Continue.
  3. Click on View and choose Show All Devices to list all detected disks and volumes.
  4. Select the drive or volume that you want to repair in the left sidebar; here, it should be Macintosh HD.
  5. Click First Aid on the top menu of Disk Utility.
  6. Click Run to check and repair errors in this drive. Wait for the process.

If Disk Utility reports operation successful or repaired, you’re free to restart your computer. Nevertheless, another situation is no disk error is found by Disk Utility. It turns out the hard drive is not responsible for Mac not booting up, then what is the reason behind Mac not turning on? You can find the answer under Safe mode.

Step 2: Boot your Mac into Safe Mode

Safe mode can determine whether an issue is caused by software that loads when your Mac starts up since it will only launch some basic necessary programs. That means it can isolate incompatibility software that makes your Mac unbootable. Really helpful, right? Here’s what you should do:

  1. Press and hold the power button until the Mac forcibly shuts down.
  2. Restart this Mac with the Shift key pressed and held to start the Mac up in Safe Mode.
  3. Release the key when you see the progress bar.

Once you boot into Safe Mode successfully, you’ll see Safe Boot at the right top. And it indicates that the unbootable Mac is caused by third-party software incompatibility. You must be wondering who’s the culprit, don’t worry, Verbose mode can help you out.

You need to reboot the Mac, then hold Command + V at startup. What catches your eye is a live report, but it will stop at the misbehaving software that prevents the Mac from booting up. Now you have caught the culprit, and all you need to do is uninstalling it in Safe Mode.

Keymagic.sys Error Boot Camp Error 3

Unfortunately, if you fail to boot into Safe Mode, it means it’s a macOS update failure. It would help if you reinstalled the macOS in Recovery mode, and reinstallation can place your data in danger. Therefore, before making any movement, you are strongly advised to restore your data with iBoysoft Data Recovery for Mac from an unbootable Mac first.

Step 3: Go to the Apple store for help.

You are here because your hard drive is safe and sound, and there’s no software incompatibility found in Verbose Mode. What else can you do to get rid of the trouble? Check the hardware inside your Mac. Please don’t be nervous; you are not required to do it yourself. Apple has many bricks-and-mortar stores, and you can easily get help there.
