您是否无法让第一排按键在 Apple 的 Mac 无线妙控(Mac)键盘(Magic Keyboard)上工作？无论(Whether)您主要使用它们来控制 macOS 中的亮度、播放和音量，还是用作应用程序特定功能的标准功能键，(standard function keys for app-specific features)如果出现问题，您肯定会注意到。
在大多数情况下，妙控键盘(Magic Keyboard)上的功能键会因与软件相关的错误、冲突设置或损坏的输入设备首选项而出现故障（并非双关语）。
在排除妙控键盘的功能键与硬件相关的问题之前，下面的故障排除提示和修复列表可以很好地帮助您让它们再次正常工作。
关闭/打开妙控键盘
如果妙控键盘(Magic Keyboard)上的功能键刚刚工作正常，那么关闭(OFF)设备，等待几秒钟，然后重新打开，可以解决任何小的技术问题。您可以在妙控键盘(Magic Keyboard)的背面找到一个ON/OFF滑动开关。
重新启动你的 Mac
重新启动Mac是解决系统相关问题的另一种快速方法，这些问题会阻止蓝牙(Bluetooth)设备正常运行。在继续进行其他修复之前先试一试。

记得按 Fn
默认情况下，妙控键盘(Magic Keyboard)上的顶行键会触发蚀刻在其上的特殊 macOS 功能 - Mission Control、Launchpad、Mute等。但是，如果要将它们用作标准功能键，则必须将它们与Fn（功能）键。
您可以在标准妙(Magic Keyboard)控键盘和带数字小键盘(Numeric Keypad)的全尺寸妙(Magic Keyboard)控键盘上找到Fn键。
禁用键盘设置
假设妙控键盘的第一行不控制任何 macOS 功能，而是用作标准功能键。在这种情况下，如果您希望它们以相反的方式工作，您必须禁用特定的键盘设置（您可能在之前的某个时候打开过该设置）。
1.在您的 Mac 上打开系统偏好设置应用程序。(System Preferences)
2. 选择键盘(Keyboard)。
3. 在键盘选项卡下，取消选中(Keyboard )使用 F1、F2 等键作为标准功能键(Use F1, F2, etc. keys as standard function keys)旁边的框。
然后，您可以使用妙控键盘的顶行键再次控制 macOS 功能。如果要将它们用作标准功能键，则必须按住Fn。
检查 Fn 键绑定
如果您可以使用第一行按键来毫无问题地控制 macOS 中的系统功能，但您无法将它们注册为标准功能键，则您可能已将不同的操作绑定到Fn键。换回来试试。
1. 打开系统偏好设置(System Preferences)并选择键盘(Keyboard)。
2. 在键盘(Keyboard )选项卡下，选择修改键(Modifier Keys)。
3. 打开功能 (fn) 键(Function (fn) Key)旁边的下拉菜单并选择fn 功能(fn Function)。
更新 Mac 的系统软件
如果您使用主要 macOS 版本的早期版本，则必须立即应用任何挂起的系统软件更新。如果没有，由于操作系统的普遍不稳定，通常会遇到与键盘相关的问题和其他问题。转到系统偏好设置(System Preferences)>软件更新以应用适用于您的(Software Update)Mac的最新更新。
(Connect)通过闪电(Lightning)连接并断开连接(Disconnect)
(Briefly)通过USB将(USB)妙控键盘(Magic Keyboard)简单地连接到Mac也可以解决顶行的问题，尤其是在最近的系统软件更新后出现的问题。现在尝试这样做。
当您使用它时，您还应该为妙控键盘的电池（如果电量太低）充电，以防止出现任何不稳定的行为。
重置蓝牙模块
如果妙控键盘(Magic Keyboard)上的第一行功能键继续导致问题，您应该重置Mac上的(Mac)蓝牙(Bluetooth)模块。
1. 按住Shift和Control键。然后，选择蓝牙(Bluetooth )状态图标或Mac 控制中心(the Mac’s Control Center)内的蓝牙(Bluetooth )控件。
2. 选择重置蓝牙模块(Reset the Bluetooth module)。
3. 选择确定(OK)。
这应该会提示您的Mac重置其蓝牙(Bluetooth)模块。您的蓝牙(Bluetooth)设备应在此期间断开连接，但不久后会自动重新连接。
出厂重置设备
如果重置 Mac 的蓝牙(Bluetooth)模块没有帮助，您必须将妙控键盘(Magic Keyboard)重置为出厂设置。
在继续之前，您必须断开通过蓝牙连接的任何其他(Bluetooth)Apple设备，因为重置过程会影响所有设备。如果您使用蓝牙(Bluetooth)鼠标或触控板，您还应该准备好有线/无线USB鼠标（或激活鼠标键(activate Mouse Keys)）以重新连接您的设备。
1. 按住Shift和Control键并选择蓝牙(Bluetooth )状态图标或控制中心内 的蓝牙控件。(Bluetooth )
2. 选择出厂重置所有连接的 Apple 设备(Factory reset all connected Apple devices)。
3. 选择确定(OK)。

5. 将妙控键盘（包括(Magic Keyboard—including)任何其他Apple设备）重新连接到Mac。
用压缩空气清洁钥匙
灰尘也会在妙控键盘(Magic Keyboard)的按键下方蔓延，导致功能键无法使用。在问题仅限于几个功能键的情况下，可以安全地假设是这种情况。
由于在不损坏其中的剪刀式开关的情况下撬出妙控键盘(Magic Keyboard)上的按键很棘手，因此，如果您周围有罐子，则吹几下压缩空气可以提供最佳的清洁机会。
首先(Start)以一定角度握住妙控键盘(Magic Keyboard)。然后，用压缩空气以之字形方式在按键下方吹气。重复操作，将键盘放在右侧，然后放在左侧。完成后，检查密钥是否正确注册。
删除蓝牙 PLIST 文件
损坏(corrupted Bluetooth Property List (PLIST) file)的蓝牙属性列表 (PLIST) 文件（存储蓝牙(Bluetooth)设备首选项）是可能导致妙(Magic) 控键盘相关(Keyboard-related)问题的另一个原因。尝试从您的Mac(Mac)中删除它。
1. 打开 Finder 并选择前往(Go)>前往文件夹(Go to Folder)。
2. 输入下面的路径并选择Go：
/Library/Preferences/
3. 按住 Control 并单击具有以下名称的PLIST文件并将其移至 Mac 的垃圾箱：
com.apple.Bluetooth.plist
重新启动(Reboot)您的Mac，然后检查妙控键盘的功能键是否正常工作。
仍有问题？
如果以上修复都没有使妙控键盘(Magic Keyboard)的第一行正常工作，则应重置 Mac 的 NVRAM 和 SMC(reset the Mac’s NVRAM and SMC)。如果它也不能做任何事情，您可能正在处理有缺陷的设备。通过将妙控键盘(Magic Keyboard)连接到另一台 Mac （如果可能）来(Mac)确认(Confirm)这一点，然后将其取出进行维修或更换。
How to Fix Function Keys Not Working on Apple Magic Wireless Keyboard
Do you have trouble getting the top row of keys to work on Apple’s wireleѕs Magic Keyboard for the Mаc? Whether you use them mаinly to control the brightness, playback, and volume in macOS or as standard function keys for app-specific features, you’ll definitely notice if something goes awry.
In most cases, the function keys on the Magic Keyboard malfunction—no pun intended—due to software-related bugs, conflicting settings, or corrupt input device preferences.
Before ruling out issues with the Magic Keyboard’s function keys not working as being hardware-related, the list of troubleshooting tips and fixes below could very well help you get them working correctly again.
Turn Magic Keyboard OFF/ON
If the function keys on the Magic Keyboard worked fine just a moment ago, then switching the device OFF, waiting for a few seconds, and turning it back ON can get rid of any minor technical problems. You can find an ON/OFF slide switch at the back edge of your Magic Keyboard.
Restart Your Mac
Restarting your Mac is another quick way to resolve system-related problems that prevent Bluetooth devices from functioning as they normally should. Give that a shot before moving on with the rest of the fixes.
Unpair and Reconnect Magic Keyboard
If the function keys are not working only occasionally, or if some of the keys don’t appear to register at all, remove Apple’s wireless Magic Keyboard and reconnect it to your Mac.
1. Open the Apple menu and select System Preferences.
2. Select Bluetooth.
3. Pick your Magic Keyboard and select the x-shaped icon next to it.
4. Select Remove to unpair the device.
5. Wait for a few seconds until the Magic Keyboard shows up within the list of Bluetooth devices again. Then, select Connect to reconnect it to your Mac.
Remember to Press Fn
By default, the top row keys on the Magic Keyboard triggers the special macOS features etched onto them—Mission Control, Launchpad, Mute, etc. If you want to use them as standard function keys, however, you must use them in conjunction with the Fn (Function) key.
You can find an Fn key on the standard Magic Keyboard and the full-sized Magic Keyboard with Numeric Keypad.
Disable Keyboard Setting
Suppose the Magic Keyboard’s top row doesn’t control any macOS features but instead works as standard function keys. In that case, you must disable a specific keyboard setting—which you may have turned on sometime earlier—if you prefer them to work the other way around.
1. Open the System Preferences app on your Mac.
2. Select Keyboard.
3. Under the Keyboard tab, uncheck the box next to Use F1, F2, etc. keys as standard function keys.
You can then use the Magic Keyboard’s top row keys to control macOS features again. If you want to use them as standard function keys, you must hold down Fn.
Check Fn Key Binding
If you can use the top row of keys to control system features in macOS without issues, but you can’t register them as standard function keys, you’ve likely bound a different action to the Fn key. Try changing it back.
1. Open System Preferences and select Keyboard.
2. Under the Keyboard tab, choose Modifier Keys.
3. Open the pull-down menu next to Function (fn) Key and select fn Function.
Update the Mac’s System Software
If you use an early release of a major macOS version, you must immediately apply any pending system software updates. If not, it’s typical to experience keyboard-related and other issues due to the operating system’s general instability. Go to System Preferences > Software Update to apply the latest updates for your Mac.
Connect via Lightning and Disconnect
Briefly connecting your Magic Keyboard to the Mac via USB can also fix problems with the top row, especially if they showed up after a recent system software update. Try doing that now.
While you’re at it, you should also top up the Magic Keyboard’s battery—if it’s too low—to prevent any erratic behavior.
Reset Bluetooth Module
If the top row of function keys on the Magic Keyboard continues to cause issues, you should reset the Bluetooth module on your Mac.
1. Hold down the Shift and Control keys. Then, select the Bluetooth status icon or the Bluetooth control inside the Mac’s Control Center.
2. Select Reset the Bluetooth module.
3. Select OK.
That should prompt your Mac to reset its Bluetooth module. Your Bluetooth devices should disconnect in the meantime but reconnect automatically soon after.
Factory Reset Device
If resetting the Mac’s Bluetooth module didn’t help, you must reset your Magic Keyboard to factory settings.
Before continuing, you must disconnect any other Apple devices connected over Bluetooth since the reset procedure affects them all. In case you use a Bluetooth mouse or trackpad, you should also have a wired/wireless USB mouse at the ready (or activate Mouse Keys) to reconnect your devices.
1. Hold down the Shift and Control keys and select the Bluetooth status icon or the Bluetooth control inside the Control Center.
2. Select Factory reset all connected Apple devices.
3. Select OK.
4. Wait for a few seconds. Then, open System Preferences and select Bluetooth.
5. Reconnect the Magic Keyboard—including any other Apple devices—to the Mac.
Clean Keys With Compressed Air
Dust can also creep underneath the keys on your Magic Keyboard and lead to function keys not working. In instances where the issue is limited to a few function keys, it’s safe to assume that that’s the case.
Since it’s tricky to pry out the keys on your Magic Keyboard without damaging the scissor switches inside them, a few blasts of compressed air—if you’ve got a can laying around—offer the best chance at cleaning them out.
Start by holding the Magic Keyboard at an angle. Then, blow underneath the keys with compressed air in a zig-zag fashion. Repeat by holding the keyboard to its right side and then the left side. Once you’ve done that, check if the keys register correctly.
Delete Bluetooth PLIST File
A corrupted Bluetooth Property List (PLIST) file—which stores Bluetooth device preferences—is another reason that can cause Magic Keyboard-related issues. Try deleting it from your Mac.
1. Open Finder and select Go > Go to Folder.
2. Type the path below and select Go:
/Library/Preferences/
3. Control-click the PLIST file with the following name and move it to the Mac’s Trash:
com.apple.Bluetooth.plist
Reboot your Mac and check if the Magic Keyboard’s function keys are working correctly after that.
Still Having Issues?
If none of the fixes above got the top row on your Magic Keyboard in working order, you should reset the Mac’s NVRAM and SMC. In case that fails to do anything as well, you’re likely dealing with a defective device. Confirm that by connecting the Magic Keyboard to another Mac (if possible) and take it out for repairs or replace it.
