MAC上非常经典的系统工具Alfred下载后一直无法打开，通过CleanApp发现有崩溃报告，通过记事本打开后提示如下：
Dyld Error Message: Library not loaded: @rpath/Alfred Framework.framework/Versions/A/Alfred Framework Referenced from: /Applications/Alfred 3.app/Contents/MacOS/Alfred 3 Reason: no suitable image found. Did find: /Applications/Alfred 3.app/Contents/MacOS/../Frameworks/Alfred Framework.framework/Versions/A/Alfred Framework: code signature in (/Applications/Alfred 3.app/Contents/MacOS/../Frameworks/Alfred Framework.framework/Versions/A/Alfred Framework) not valid for use in process using Library Validation: mapped file has no Team ID and is not a platform binary (signed with custom identity or adhoc?) /Applications/Alfred 3.app/Contents/MacOS/../Frameworks/Alfred Framework.framework/Versions/A/Alfred Framework: stat() failed with errno=1
通过Google搜索其中一段代码：
Reason: no suitable image found. Did find: /Applications/Alfred 3.app/Contents/MacOS/../Frameworks/Alfred
找到一个网页https://www.reddit.com/r/techsupport/comments/avrq2u/cannot_open_an_application/
有个网友在最后回复
Oh I know that. We should disable SIP protection in mac, which will solve this problem.
然后我在百度搜索 ：MAC SIP
找到：https://www.jianshu.com/p/fe78d2036192（Mac开启关闭SIP（系统完整性保护））
根据该办法关闭了SIP后，Alfred可以成功使用，谨在此把解决问题的思路和方法记录一下，希望能帮助到有需要的人，以及给自己备用。
注：在关闭SIP之前，我已经设置了“允许任何来源下载的应用”。至于如何更改这个设置，https://blog.csdn.net/xuefujin/article/details/80264471 有解决方案。
至于Alfred最新版我就不共享了，网上一大堆，这个软件用惯了还真的有依赖性，非常好用哦。
