官⽅解决办法：不可恢复的错误。s...
提前告知：重装系统没⽤！重装系统没⽤！重装系统没⽤！，⼤家不要⾛弯路
最终的答案是：
r m "/Vo lumes/<yo ur disk>/va r/db/a uth.db"
lum es/r/
将这⼀⾏命令在终端输⼊，然后重启Ma c。

不着急的同学，听我讲故事哈：
----------------------------------------------------------------------------------------------------------
新买了⼀个⼆⼿的Mac mini，想体会下远程协助功能。安装了 Teamviewer。
实际来看，Teamviewer并不好⽤或者说不符合我的要求，就习惯性的⽤CleanMymac X 卸载了 Teamviewer。
结果重启之后就出现了：不可恢复的错误。securityagent⽆法创建所要求的机制teamviewerauthplugin:start  点了⼏次后发现⽆解，只能诅咒Teamviewer NDY
图⽚引⾃：My_Fuzz的简书，www.jianshu/p/6de057c6004f
然后，百度和Google了⼀通。到了⼏个看起来⽐较靠谱的办法，什么下载：TeamViewerAuthPlugin.bundle，拷⼊U盘，。。。。。尝试了⼀通之后还是没⽤。
然后，想着重新安装macOS吧，这样应该可以。
化了好⼏个⼩时装好后，重启电脑，⼜是不可恢复的错误没⽤？没⽤
只能再次诅咒  Teamviewer    CNDY CNDY
然后，想了下，应该去Teamviewer 官⽹投诉，果然发现不少⽹友有类似的问题
然后，到了官⽅的解释：
Re：在Mac OS Catalina上卸载Teamviewer后⽆法启动
可能是由于在macOS上删除了⼀个授权插件（在这种情况下为TeamViewerAuthPlugin.bundle）⽽没有先注销它⽽引起的。
我们建议始终使⽤TeamViewer中的内置卸载程序（“⾸选项”>“⾼级”）。这样可以确保在删除插件之前
已正确注销了该插件。
我们建议始终使⽤TeamViewer中的内置卸载程序（“⾸选项”>“⾼级”）。
在我的测试中，CleanMyMac X 4.4.5之前的版本似乎在删除插件⽽未注销它，因此可能导致了问题。如果您使⽤CleanMyMac X，则需要确保使⽤最新版本。
如果您⽆法还原插件，则可以删除Mac的授权数据库。您的Mac在下次启动时会重新创建丢失的数据库（使⽤⼀些适合⼤多数⽤户的默认设置）。
按住Cmd-R直到出现Apple徽标，在macOS Recovery中启动Mac。
Mac启动到macOS Recovery后，您应该会看到⼀个名为“ macOS Utilities”的窗⼝。
要删除授权数据库，需要安装Mac的硬盘，并且您需要知道其名称（通常是“ Macintosh HD”或“ macOS”之类的名称）。
打开“磁盘⼯具”，然后在左侧栏中查看磁盘名称。对于运⾏Catalina的Mac，寻不以“-数据”结尾的名称。
在侧边栏中选择磁盘。
单击⼯具栏中的“安装”（如果您仅看到“卸载”，则它已安装，您⽆需执⾏任何操作）。
退出磁盘实⽤程序。
您应该回到“ macOS Utilities”窗⼝。
从屏幕顶部的菜单栏中，打开“实⽤程序”>“终端”。
输⼊命令
rm“ /卷/ <；您的磁盘> /var/db/auth.db”
将<your disk>替换为内置硬盘的名称，
例如：rm“ /卷/ Macintosh HD / var / db / auth.db”
请确保不要忘记引号，以防您的磁盘名称包含空格。
重新启动Mac。
以上是翻译的中⽂，下⾯是英语原⽂：
teamviewerRe: Can't Boot after uninstalling Teamviewer on Mac OS Catalina
This issue can be caused by deleting an authorization plugin on macOS (in this case, TeamViewerAuthPlugin.bundle) without de-registering it first.
We recommend always using the built-in uninstaller in TeamViewer (Preferences > Advanced). This makes sure We recommend always using the built-in uninstaller in TeamViewer (Preferences > Advanced).
that the plugin is properly de-registered before deletion.
In my tests,  CleanMyMac X versions prior to 4.4.5 seem to be deleting the plugin without de-registering it, so that could have caused the issue. If you use CleanMyMac X, you'll want to make sure to use the newest version.
If you do not have the possibility to restore the plugin as described by @Mrsharifi, you may instead be able to delete your Mac's authorization database. Your Mac re-creates a missing database during the next startup (using some default settings that are fine for most users).
Start your Mac in macOS Recovery by holding down Cmd-R until the Apple logo appears.
Once your Mac has booted into macOS Recovery, you should see a window titled "macOS Utilities".
To delete the authorization database, your Mac's hard disk needs to be mounted and you will need to know its name (usually something like "Macintosh HD" or "macOS").
Open Disk Utility and check the left sidebar for the name of your disk. For Macs running Catalina, look for the name that
does not end in "- Data".
Select the disk in the sidebar.
Click "Mount" in the toolbar (if you only see "Unmount", it is already mounted and you don't need to do anything). Quit Disk Utility.
You should be back at the "macOS Utilities" window.
From the menu bar on top of the screen, open Utilities > Terminal.
Enter the command
r m "/Vo lumes/<yo ur disk>/va r/db/a uth.db"
lum es/r/
Replace with the name of your built-in hard disk, e.g.
rm "/Volumes/Macintosh HD/var/db/auth.db"
Make sure not to forget the quotes in case your disk name contains spaces.
Restart your Mac.
