No sound in Windows on a MacBook Pro after a UEFI install: how to fix it

Windows has no sound on a MacBook Pro when Apple's Boot Camp drivers are missing, and on a 2011 or older MacBook Pro installed in UEFI mode Apple offers no supported audio driver at all.

This guide shows how to tell which case you have, how to install or repair the Boot Camp audio drivers, and how to get sound back on a 2011 model.

How to fix MacBook Pro UEFI Windows sound

Match the Mac to Apple's Windows support list first, because the fix depends on the model year.

  1. In macOS, choose Apple menu > About This Mac and note the model name, such as MacBook Pro (13-inch, Early 2011).
  2. If the MacBook Pro is from 2012 or later, start up in Windows and open the BootCamp folder on the OSXRESERVED partition, usually the D: drive.
  3. Open Setup from that folder, click Yes when Boot Camp asks to make changes, then click Repair.
  4. Click Finish, then click Yes to restart the Mac.
  5. If the MacBook Pro is from 2011 or earlier and Windows 10 was installed in UEFI mode, reinstall Windows with Boot Camp Assistant using a Windows version Apple lists for that model.
  6. After the restart, open Settings > System > Sound and select the built-in speakers under Output.

Which MacBook Pro models support Windows 10 with Boot Camp

Apple publishes a separate support list for each Windows version. Windows 10 support starts with the 2012 MacBook Pro, while the 2011 models stop at Windows 8.1.

Windows version MacBook Pro models Apple supports Boot Camp support software
Windows 10 2012 to 2020, excluding MacBook Pro (13-inch, M1, 2020) Installed by the Boot Camp installer after setup
Windows 8.1 15-inch and 17-inch Mid 2010 through Retina Mid 2015, including all 2011 models Boot Camp 6 adds support for some Mac features
Windows 7 64-bit All 2011 MacBook Pro models (13-inch, 15-inch and 17-inch, Early and Late 2011) Version 5
Windows 7 32-bit All 2011 MacBook Pro models Version 4

Windows 7 reached end of support on January 14, 2020, and Windows 8.1 on January 10, 2023. Neither receives security updates from Microsoft now.

How to find your MacBook Pro model year

The model name decides which Boot Camp drivers exist for the Mac. Apple pairs every model name with a model identifier, which Windows also shows as the System Model when you find the computer model in Windows.

  1. Start up the Mac in macOS.
  2. Choose Apple menu > About This Mac.
  3. Read the model name, for example MacBook Pro (15-inch, Late 2011).
  4. Compare the year with the Windows support table above.
  5. If you see the identifier instead of the name, MacBookPro8,1, MacBookPro8,2 and MacBookPro8,3 are the 13-inch, 15-inch and 17-inch 2011 models.
  6. MacBookPro9,1 and MacBookPro9,2 are the 15-inch and 13-inch Mid 2012 models, the oldest MacBook Pro models on Apple's Windows 10 list.

How to check if Windows is installed in UEFI mode on a MacBook Pro

System Information in Windows shows the firmware mode Windows started in.

  1. Select Start and type msinfo32 in the search box.
  2. Open System Information from the results.
  3. Select System Summary in the left pane.
  4. Read the BIOS Mode value on the right.
  5. UEFI means Windows was installed in UEFI mode; Legacy means it started in legacy BIOS mode.

On a 2011 MacBook Pro running Windows 10, a UEFI value confirms a setup that sits outside Apple's support list. Community workarounds that patch the firmware tables for audio are not supported by Apple.

Install Boot Camp drivers to fix MacBook Pro sound

The Boot Camp installer puts Apple's Windows support software, including the drivers, on the Mac. Running it again with Repair restores a missing audio driver.

Connect a USB mouse or keyboard first, because Bluetooth input may not work until the drivers are installed.

  1. Start up the Mac in Windows.
  2. Open File Explorer and open the OSXRESERVED partition, usually drive D:.
  3. Open the BootCamp folder and run Setup from that folder.
  4. Click Yes when Boot Camp asks to make changes to your device.
  5. Click Repair to start the installation.
  6. Click Finish, then click Yes to restart the Mac.

From Command Prompt, the same installer runs with D:\BootCamp\setup.exe. The package also restores the keyboard keys, so it can fix Boot Camp brightness control at the same time.

Download Windows support software for MacBook Pro sound

Use this route when the Mac has no OSXRESERVED partition. Apple lists no audio from the built-in speakers in Windows as one of the problems it fixes.

  1. In macOS, install the latest macOS updates.
  2. Open Disk Utility from Applications > Utilities, choose View > Show All Devices, and select a USB flash drive of 16GB or more.
  3. Click Erase, choose MS-DOS (FAT) as the format and Master Boot Record as the scheme, then erase the drive.
  4. Open Boot Camp Assistant from Applications > Utilities.
  5. From the Action menu, choose Download Windows Support Software and save it to the USB drive.
  6. Start up in Windows with the USB drive connected, then open Setup in the WindowsSupport or BootCamp folder on the drive.
  7. Click Repair, then click Finish and restart the Mac.

If Windows warns that the software has not passed Windows Logo testing, choose Continue Anyway.

Update Boot Camp audio drivers in Windows 10

Boot Camp support software updates come from both Windows Update and Apple Software Update, so install what each one offers before you reinstall the audio driver by hand.

  1. Open the Start menu, choose Settings, then select Update & Security.
  2. Click Check for updates and install the updates Windows offers.
  3. Open the Start menu and choose Apple Software Update.
  4. Select the available updates and click Install.
  5. Follow the onscreen instructions, then restart the Mac.

Apple Software Update checks once a week by default. Change that in Edit > Preferences.

Reinstall Windows on a 2011 MacBook Pro with Boot Camp Assistant

A 2011 MacBook Pro gets Apple audio drivers only through a Boot Camp Assistant install of Windows 7 or Windows 8.1. Back up the Windows files you want to keep before you start.

  1. In macOS, install the latest updates available for the Mac.
  2. Open Boot Camp Assistant from the Utilities folder in Applications.
  3. Follow the onscreen instructions and choose a size for the Windows partition.
  4. Let the Mac restart into Windows Setup and install Windows on the BOOTCAMP partition.
  5. When Windows starts, let the Boot Camp installer add the Windows support software, then restart.
  6. To switch between macOS and Windows, restart and hold the Option key.

Both Windows versions Apple supports on 2011 models are past end of support, so weigh that before relying on this setup.

MacBook Pro UEFI Windows sound FAQ

Why is there no sound in Windows on my MacBook Pro?

The usual cause is a missing Boot Camp audio driver. Run Setup from the BootCamp folder and click Repair. On a 2011 or older MacBook Pro with Windows 10 in UEFI mode, Apple provides no supported driver, so reinstall Windows with Boot Camp Assistant.

No. Apple's Windows 10 list for MacBook Pro starts with the 2012 models. The 2011 MacBook Pro models are supported with Windows 7 and Windows 8.1, both of which are now past Microsoft's end of support.

Where are the Boot Camp drivers on a Mac?

After a Boot Camp Assistant install, the drivers sit in the BootCamp folder on the OSXRESERVED partition, usually drive D: in Windows. Without that partition, download Windows Support Software to a USB drive from the Action menu in Boot Camp Assistant.

On a UEFI PC, bcdboot C:\Windows copies fresh boot files from the Windows folder to the EFI system partition and adds a Windows Boot Manager entry to the firmware boot list. On a Mac, Boot Camp Assistant manages the Windows partition.

Not officially. Microsoft does not support MBR2GPT conversion of disks with Windows 7, 8 or 8.1 installed. It recommends upgrading to a supported Windows version first, then converting the disk.
