当您通过Sidecar(Sidecar)将 Mac 的显示屏扩展或镜像到 iPad 时，您的 iPad 是否会经常死机？造成这种情况的原因通常有多种，例如技术故障、通信故障和设置冲突。
本故障排除指南将揭示多种解决方案来修复iPad、iPad mini、iPad Air或 iPad Pro上的(Pro)Sidecar冻结问题。
1. 关闭和打开 Sidecar
如果Sidecar正常工作但突然不工作，请考虑断开 iPad 与Mac 的(Mac)连接，然后重新连接。这就像快速刷新一样，通常可以解决意想不到的问题。
为此，请从Mac屏幕右上角打开“屏幕镜像”(Screen Mirroring)状态菜单，然后选择 iPadOS 设备 - 这应该会结束Sidecar。然后，等待最多 10 秒并启动新会话。
如果您的 iPad通过USB物理连接到Mac ，则最好在再次调用(Mac)Sidecar之前暂时拔下电缆并重新插入。
2. 重启两台设备
如果问题仍然存在，请重新启动(iPad a fresh start by restarting them)您的 Mac(give both your Mac)和iPad，让它们重新开始。通过重新启动两个设备的Wi-Fi和蓝牙(Bluetooth)模块并刷新Handoff等底层功能，可以消除Sidecar 的(Sidecar)随机问题。
要重新启动Mac，请在Apple菜单上选择(Apple)“重新启动(Restart)”，取消选中“重新登录时重新打开窗口”框，然后再次选择(Reopen)“重新启动”(Restart)进行确认。
在 iPad 上，转到General > Shutdown，关闭设备，然后在 30 秒后按住电源(Power)按钮。
3.确保两台设备都是最新的
在深入进行更深入的故障排除之前，必须确保您的 iPad 和Mac安装了最新的操作系统更新。Apple经常发布补丁来解决Sidecar等核心功能的兼容性和性能问题。
要更新您的Mac，请打开Apple菜单并转至System Settings > General > Software Update。如果有待处理的 macOS 更新，请选择“立即更新”(Update)。
在 iPad 上，打开“设置”(Settings)应用程序并转到General > Software Update—tap Download并安装”(Install)以应用可用更新。
4. 消除连接问题
Sidecar很大程度上依赖于(Sidecar)Mac和 iPad之间的稳定连接。如果设备以无线方式相互通信，请确保它们距离很近，并且附近没有干扰源，例如非屏蔽电源线、荧光灯和厨房设备。选择(Opt)使用 USB-C 或 Lightning 线缆进行有线连接，以改善连接性并消除延迟。
5.禁用通用控制
通用控制让您可以在多台(Universal Control)Mac和 iPad 设备上使用一个键盘和鼠标/触控板。然而，它往往与Sidecar发生冲突。尝试关闭通用控制(Universal Control)以查看是否可以解决冻结问题。
要在Mac上禁用通用控制(Universal Control)，请转至System Settings > Displays > AdvancedMac或 iPad
之间移动旁边的开关。
在 iPad 上，转到Settings > General > AirPlay和切换”(Handoff)，然后关闭光标(Cursor)和键盘(Keyboard)开关。
6. 更新您的 Mac 应用程序
如果Sidecar仅在您将特定(Sidecar)Mac应用程序移动到 iPad 屏幕上时才起作用，请考虑更新该应用程序。如果您是从Mac App Store(Mac App Store)获取的，则可以通过店面的“更新”(Updates)选项卡进行更新。如果没有，请在应用程序中查找“检查(Check)更新”(Updates)等选项，以确保您拥有最新版本。了解有关更新 Mac 上的应用程序(updating apps on the Mac)的更多信息。
7. 禁用自动锁定
论坛讨论(Forum chatter)表明禁用iPad 上的自动锁定(Auto Lock on the iPad)作为解决Sidecar冻结问题的潜在解决方案。要尝试此操作，请打开“设置”(Settings)应用，点击“显示(Display)和Brightness > Auto-Lock，然后选择“从不”(Never)。使用完Sidecar后，(Sidecar)请记住(Remember)重新激活“自动锁定”(Auto Lock)。
8. 禁用面容 ID

请(Feel)随时重新启用Face ID 。
9.禁用后台应用程序
在Mac(Mac)和 iPad后台运行的第三方应用程序和服务可能会干扰Sidecar，因此检查并禁用任何不必要的内容是个好主意。
在Mac上转至System Settings > General > Login Items“登录(Login)时打开(Open)”下的列表中删除不需要的登录项目。接下来(Next)，向下滚动到“允许(Allow)在后台”(Background)部分，然后关闭您不需要的应用程序旁边的开关。
在 iPad 上，转到Settings > General > Background App Refresh，以阻止应用程序在您不经常使用时自行更新。
完美的边车
由于影响因素很多，Sidecar 冻结问题的排查可能会很困难。如果您确实解决了问题，请保持 iPad 和Mac上的系统软件为最新版本，以尽量减少今后遇到类似问题。如果上述修复均无效，请联系 Apple 支持(contact Apple Support)。
iPad Sidecar Keeps Freezing? 9 Fixes to Try
Does your iPad cоnstantly frеeze when you extend or mirror your Mac’s display to it via Sidecar? Various reasons—such as technical glitches, communication breakdowns, and settings conflicts—often cause that.
This troubleshooting guide will reveal multiple solutions to fix Sidecar freezes on your iPad, iPad mini, iPad Air, or iPad Pro.
1. Toggle Sidecar Off and On
If Sidecar was working but suddenly isn’t, consider disconnecting your iPad from your Mac and reconnecting it. That acts like a quick refresh, often resolving unexpected issues.
To do that, open the Screen Mirroring status menu from the top right of the Mac screen and select the iPadOS device—this should end Sidecar. Then, wait up to 10 seconds and initiate a fresh session.
If your iPad is physically connected to your Mac via USB, it’s also best to briefly remove the cable and plug it back in before invoking Sidecar again.
2. Restart Both Devices
If the problem persists, give both your Mac and iPad a fresh start by restarting them. That could clear random hiccups with Sidecar by rebooting both devices’ Wi-Fi and Bluetooth modules and refreshing underlying features like Handoff.
To restart your Mac, select Restart on the Apple menu, uncheck the Reopen windows when logging back in box, and select Restart again to confirm.
On your iPad, go to General > Shutdown, turn off the device, and hold down the Power button after 30 seconds.
3. Ensure Both Devices Are Up-to-Date
Before diving into more in-depth troubleshooting, it’s essential to ensure your iPad and Mac have the latest operating system updates installed. Apple frequently releases patches to address compatibility and performance issues with core functionalities like Sidecar.
To update your Mac, open the Apple menu and go to System Settings > General > Software Update. If there’s a pending macOS update, select Update Now.
On the iPad, open the Settings app and go to General > Software Update—tap Download & Install to apply available updates.
4. Eliminate Connectivity Issues
Sidecar relies heavily on a stable connection between your Mac and iPad. If the devices talk to each other wirelessly, ensure they are close, and there are no sources of interference nearby—e.g., unshielded power cables, fluorescent lights, and kitchen equipment. Opt for a wired connection with a USB-C or Lightning cable to improve connectivity and eliminate lag.
5. Disable Universal Control
Universal Control lets you use one keyboard and mouse/trackpad across multiple Mac and iPad devices. However, it tends to clash with Sidecar. Try turning off Universal Control to see if it fixes the freezing problems.
To disable Universal Control on a Mac, go to System Settings > Displays > Advanced and disable the switch next to Allow your pointer and keyboard to move between any nearby Mac or iPad.
On your iPad, go to Settings > General > AirPlay & Handoff and turn off the Cursor and Keyboard switch.
6. Update Your Mac Apps
If Sidecar acts up only when you move a particular Mac app to your iPad’s screen, consider updating that app. If you got it off the Mac App Store, you can update it via the storefront’s Updates tab. If not, look within the app for an option like Check for Updates to ensure you have the latest version. Learn more about updating apps on the Mac.
7. Disable Auto Lock
Forum chatter indicates disabling Auto Lock on the iPad as a potential fix for resolving freezes with Sidecar. To try that out, open the Settings app, tap Display & Brightness > Auto-Lock, and choose Never. Remember to re-activate Auto Lock once you’ve finished using Sidecar.
8. Disable Face ID
Another helpful—albeit less convenient—option involves disabling Face ID on your iPad’s Lock Screen. If you don’t mind having to punch in your passcode, go to Settings > Face ID & Passcode and turn off the switch next to iPad Unlock. Feel free to re-enable Face ID after completing your Sidecar session.
9. Disable Background Apps
Third-party apps and services running in the background of your Mac and iPad can interfere with Sidecar, so reviewing and disabling anything unnecessary is a good idea.
Go to System Settings > General > Login Items on your Mac and remove unwanted login items from the list under Open at Login. Next, scroll down to the Allow in the Background section and turn off the switches next to the apps you do not want.
On your iPad, go to Settings > General > Background App Refresh to stop apps from updating themselves when you aren’t actively using them.
The Perfect Sidecar
Sidecar freezes can be challenging to troubleshoot due to the number of potential factors at play. If you do manage to fix the problem, keep the system software on your iPad and Mac up to date to minimize running into similar issues going forward. If none of the fixes above helped, it’s time to contact Apple Support.
