您的Mac(Mac)上没有打开Steam客户端吗？这是一个烦人的问题，新旧安装都可能发生。许多原因（例如权限不足、与软件相关的错误和损坏的文件）通常会导致它。值得庆幸的是，它很容易修复（至少在大多数情况下是这样）。
通过接下来的修复工作，您应该能够让Steam快速启动并运行。
注意：(Note:) 您(Are)使用的是 PC 而不是Mac？如果 Steam 无法在 Windows 上打开，(fix Steam if it doesn’t open on Windows)您必须执行以下操作来修复它。
1. 强制退出并重启 Steam如果Steam刚在启动时死机（发生这种情况时，您可能会看到Steam图标在 Mac 的(Steam)Dock上反复弹跳），请尝试强制退出该应用程序。这可以帮助消除问题背后的任何随机故障。
为此，请打开Apple菜单并选择Force Quit。在随后出现的Force Quit Applications框中，选择Steam并选择Force Quit。最多等待 10 秒，然后重新启动 Steam。
或者，您可以通过活动监视器退出卡住的(Activity Monitor)Steam实例，然后再重新打开它。
首先(Start)通过Spotlight Search搜索并打开活动监视器(Activity Monitor)（按Command + Space来调用它）。然后，在CPU选项卡下，选择Steam进程并选择窗口顶部的停止按钮。(Stop )
在重新启动 Steam 之前，您还应该扫描列表中的其他 Steam 相关进程（例如Steam Helper）。
3.重启Mac如果Steam仍然无法打开，您必须重新启动Mac。这是解决 macOS 中出现的最常见错误和故障的一种非常有效的方法。只需(Just)在选择Restart之前取消选中重新登录时重新打开窗口(Reopen windows when logging back in)选项即可。
服务器端问题也可能会阻止 Steam 在您的Mac上打开。要检查是否是这种情况，请访问非官方的 Steam 服务器状态页面(unofficial Steam Server Status page)。
如果您看到列出的任何问题，您必须等到Valve修复它们。只要(Just)记住在一切恢复在线后重新启动它之前强制退出Steam 。
5. 提供无障碍权限(Accessibility Permissions)Steam应用程序需要访问权限才能在您的Mac上(Mac)正确运行。如果您刚刚安装它，您应该会自动收到一个提示，要求您安装它。但是，如果您错过或忽略了它，这就是您必须做的。
首先打开Apple菜单，然后转到System Preferences > Privacy & Security > Privacy。然后，选择侧边栏上的辅助功能(Accessibility)，选择单击锁进行更改，然后选中(Click the lock to make changes)Steam旁边的框。
如果您在应用程序列表中没有看到Steam，请选择加(Plus )号按钮并从 Mac 的应用程序(Applications )文件夹中添加它。
6. 删除 Steam 偏好损坏的 Steam首选项还可以阻止应用程序在(Corrupt Steam)Mac上打开。尝试(Try)删除它们。为此，请打开Finder，按Command + Shift + G调出 Go to Folder框，然后访问以下文件夹：
~/Library/Preferences~/Library/Application Support/Steam然后，删除每个目录中的PLIST（属性列表(Property List)）文件。通过重新启动Steam(Steam)来遵循这一点。
如果您在Mac上设置了错误的日期和时间，Steam 可能无法启动。转到系统偏好设置(System Preferences)>日期和时间(Date & Time)以配置您的日期和时间设置。
让您的Mac自动为您设置正确的时间，或者确保它们与您居住的时区相匹配。如果您在正确设置日期和时间时遇到任何问题，您必须重置 Mac 的 NVRAM(reset your Mac’s NVRAM)。
8.禁用防病毒软件防病毒软件还可以阻止 Steam 在(Antivirus)Mac上打开。如果您确实使用了第三方安全实用程序，请尝试禁用它。
如果提示Steam正常加载，请访问防病毒实用程序的配置窗格并将Steam添加为例外。
9. 强制更新 Steam更新 Steam 有助于修复阻止程序在您的Mac上启动的已知错误。但由于您无法打开 Steam 来执行此操作，因此您必须改用变通方法。
首先强制退出Steam（如果它在启动时显示冻结）。然后，打开Finder应用程序并选择侧边栏上的应用程序(Applications )。接下来，按住 Control 单击Steam，选择Show Package Contents，然后导航到Contents > MacOS文件夹。
最后，运行标有 steam_osx(steam_osx)的文件。终端(Terminal)窗口应该会自动启动并更新Steam。
如果之前的方法没有更新Steam ，您可以尝试在(Steam)终端(Terminal)中运行特定命令来应用挂起的更新。
首先前往Finder > Applications > Utilities > Terminal。然后，复制并粘贴以下命令并按Enter：
/Applications/Steam.app/Contents/MacOS/steam.sh
除了更新之外，您还可以尝试重新下载Steam以解决安装文件损坏的问题。为此，请打开Finder并按Command + Shift + G。然后，访问以下目录并删除其中的Steam.AppBundle文件夹：
~/Library/Application Support/Steam
通过重新启动Steam(Steam)来遵循这一点。该程序应自动下载并重新安装。
Mac的系统软件问题也会导致 Steam 在Mac上无法正常打开。因此，如果您最近没有更新它，您现在应该这样做。
打开Apple菜单并转到系统偏好设置(System Preferences )>软件更新(Software Update)。然后，选择立即(Now )更新(Update) 以应用任何挂起的系统软件更新。
如果您的Mac在安装系统软件更新时遇到问题，您可以采取以下措施来解决此问题(here’s what you can do to fix that)。
13.删除并重新安装Steam如果上述修复均无效，则应从头开始在Mac上重新安装(Mac)Steam 。但请放心，您可以选择保持游戏数据完好无损。
为此，请在Finder中打开转到(Finder)文件夹(Folder)框并打开以下目录：
~Library/Application Support/Steam
然后，删除除steamapps文件夹（包含您下载的游戏数据）之外的所有文件和文件夹。
然后将Steam(Steam )从 Mac 的Applications文件夹拖到Trash。
然后，下载适用于 macOS(Steam installer for macOS)的最新版Steam 安装程序并重新安装Steam。希望(Hopefully)该程序随后应该可以毫无问题地打开。
Steam 已在 Mac 上修复上面的修复肯定会帮助您修复Mac上的 Steam 。如果强制退出和重新启动应用程序不起作用，其余的解决方案很可能让它再次正确加载。但是，如果您继续遇到问题，您必须联系 Steam 支持(contact Steam Support)。他们可能会提供特定于您的 Mac 配置的其他解决方案，有望永久解决问题。
Steam Not Opening on Mac? 13 Ways to FixIs the Steam client not opening on your Mac? Іt’s an annoying isѕue that can occur with both new and old installations. Many reаsons—such as insufficient permissions, software-related bugs, and сorrupted files—often сause іt. Thankfully, it’s easily fixable (at least it is most of the time).
Work your way through the fixes that follow, and you should be able to get Steam up and running quickly.
Note: Are you using a PC instead of a Mac? Here’s what you must do to fix Steam if it doesn’t open on Windows.
1. Force-Quit and Restart SteamIf Steam just froze at launch (you may see the Steam icon repeatedly bouncing on the Mac’s Dock when that happens), try force-quitting the app. That can help get rid of any random glitches behind the issue.
To do that, open the Apple menu and select Force Quit. On the Force Quit Applications box that then shows up, choose Steam and select Force Quit. Wait for up to 10 seconds before relaunching Steam.
Alternatively, you can quit a stuck instance of Steam via the Activity Monitor before going for another shot at reopening it.
Start by searching for and opening the Activity Monitor via Spotlight Search (press Command + Space to invoke it). Then, under the CPU tab, pick the Steam process and select the Stop button at the top of the window.
You should also scan the list for other Steam-related processes (such as Steam Helper) before relaunching Steam.
3. Restart MacIf Steam still fails to open, you must restart your Mac. That’s an incredibly effective way to resolve most common bugs and glitches that crop up in macOS. Just uncheck the Reopen windows when logging back in option before selecting Restart.
Server-side issues can also stop Steam from opening on your Mac. To check if that’s the case, visit the unofficial Steam Server Status page.
If you see any issues listed, you must wait until Valve fixes them. Just remember to force-quit Steam before relaunching it once everything’s back online.
5. Provide Accessibility PermissionsThe Steam app requires accessibility permissions to run correctly on your Mac. If you just installed it, you should automatically receive a prompt asking you for that. But if you missed or ignored it, here’s what you must do.
Start by opening the Apple menu and go to System Preferences > Privacy & Security > Privacy. Then, choose Accessibility on the sidebar, select Click the lock to make changes, and check the box next to Steam.
If you don’t see Steam among the list of apps, select the Plus button and add it from the Mac’s Applications folder.
6. Delete Steam PreferencesCorrupt Steam preferences can also prevent the app from opening on the Mac. Try deleting them. To do that, open Finder, press Command + Shift + G to bring up the Go to Folder box, and visit the following folders:
~/Library/Preferences~/Library/Application Support/SteamThen, delete the PLIST (Property List) files inside each directory. Follow that by relaunching Steam.
Steam may fail to launch if you have the incorrect date and time set up on your Mac. Go to System Preferences > Date & Time to configure your date and time settings.
Let your Mac set the correct time for you automatically, or make sure that they match the time zone where you live. If you have any trouble setting up the date and time correctly, you must reset your Mac’s NVRAM.
8. Disable Antivirus SoftwareAntivirus software can also stop Steam from opening on a Mac. If you do use a third-party security utility, try disabling it.
If that prompts Steam to load normally, visit the anti-virus utility’s configuration pane and add Steam as an exception.
9. Force-Update SteamUpdating Steam can help patch out known bugs preventing the program from launching on your Mac. But since you can’t open Steam to do that, you must use a workaround method instead.
Begin by force-quitting Steam (if it appears frozen at startup). Then, open the Finder app and select Applications on the sidebar. Next, control-click Steam, select Show Package Contents, and navigate into the Contents > MacOS folders.
Finally, run the file labeled steam_osx. A Terminal window should launch and update Steam automatically.
If the previous method didn’t update Steam, you could try running a specific command in Terminal to apply pending updates.
Start by heading over to Finder > Applications > Utilities > Terminal. Then, copy and paste the following command and press Enter:
/Applications/Steam.app/Contents/MacOS/steam.sh
Updating aside, you can also try redownloading Steam to patch out issues with corrupt installation files. To do that, open Finder and press Command + Shift + G. Then, visit the following directory and delete the Steam.AppBundle folder inside it:
~/Library/Application Support/Steam
Follow that by relaunching Steam. The program should download and reinstall automatically.
Issues with the Mac’s system software can also prevent Steam from opening on Mac normally. So if you haven’t updated it recently, you should do that now.
Open the Apple menu and go to System Preferences > Software Update. Then, select Update Now to apply any pending system software updates.
If your Mac runs into trouble installing system software updates, here’s what you can do to fix that.
13. Delete and Reinstall SteamIf none of the fixes above worked, you should reinstall Steam on your Mac from scratch. But don’t worry—you can choose to keep your game data intact.
To do that, open the Go to Folder box in Finder and open the following directory:
~Library/Application Support/Steam
Then, delete all the files and folders inside except for the steamapps folder (which contains your downloaded game data).
Follow by dragging Steam from Mac’s Applications folder to the Trash.
Then, download the latest version of the Steam installer for macOS and reinstall Steam. Hopefully, the program should then open without issues afterward.
Steam Fixed on MacThe fixes above should’ve surely helped you fix Steam on the Mac. If force-quitting and relaunching the app didn’t work, the rest of the solutions most likely got it to load correctly again. However, if you continue to experience issues, you must contact Steam Support. They may provide additional solutions specific to your Mac’s configuration that could hopefully address the problem for good.
