原因是主程序对 libonigwrap.dylib 的引用是 裸库名（没有路径前缀） 解决方法在最后

经终端输入find /Applications/Steam++.app -name "*.dylib" | grep onig
和手动查找包文件内确认含有libonigwrap.dylib后，
检查文件完整是否损坏
file /Applications/Steam++.app/Contents/MonoBundle/libonigwrap.dylib
正常应该输出类似 Mach-O 64-bit dynamically linked shared library x86_64
于是验证文件完整，输入
##1. 查看主程序如何引用 libonigwrap.dylib
otool -L /Applications/Steam++.app/Contents/MacOS/Steam++ | grep onig
##2. 查看 libonigwrap.dylib 自身的安装名称
otool -D /Applications/Steam++.app/Contents/MonoBundle/libonigwrap.dylib
##3. 查看 libonigwrap.dylib 依赖的其他库
otool -L /Applications/Steam++.app/Contents/MonoBundle/libonigwrap.dylib
##4. 检查主程序所有的 LC_LOAD_DYLIB 和 LC_RPATH 信息
otool -l /Applications/Steam++.app/Contents/MacOS/Steam++ | grep -E "(LC_LOAD_DYLIB|LC_RPATH)" -A2
从输出可以看到otool -L 显示主程序对 libonigwrap.dylib 的引用是 libonigwrap.dylib（没有路径前缀）。
而 otool -l 的输出显示，主程序有多个 LC_LOAD_DYLIB，其中一条是 name libonigwrap.dylib (offset 24)，确实没有 @rpath/ 或 @executable_path 前缀。
同时，输出中也显示了两个 LC_RPATH 条目，路径分别是 @executable_path/../MonoBundle/ 和 @executable_path/../MonoBundle（带和不带斜杠）。这两个路径都正确指向了 MonoBundle。
问题关键： 主程序对 libonigwrap.dylib 的加载命令是裸库名（无路径），而 dyld 对于这种裸库名，不会使用 @rpath。它只会搜索默认路径（如 /usr/lib、/usr/local/lib 等），而不会搜索 @rpath 指定的路径。这就是为什么即使添加了 rpath，dyld 仍然尝试空路径（即默认路径）而找不到。
解决方案：修改主程序对 libonigwrap.dylib 的加载命令，将其改为 @rpath/libonigwrap.dylib。
输入
install_name_tool -change libonigwrap.dylib @rpath/libonigwrap.dylib /Applications/Steam++.app/Contents/MacOS/Steam++
然后再重新签名（因为二进制被修改过）：
codesign --force --deep --sign - /Applications/Steam++.app
双击启动 Steam++，应该可以正常打开了
在 macOS 中，裸库名的查找规则是只在默认系统库路径（如 /usr/lib、/usr/local/lib）中搜索，而不会使用 @rpath 指定的路径（即使你已经添加了正确的 rpath）。
原因是主程序对 libonigwrap.dylib 的引用是 裸库名（没有路径前缀） 解决方法在最后

经终端输入find /Applications/Steam++.app -name "*.dylib" | grep onig
和手动查找包文件内确认含有libonigwrap.dylib后，
检查文件完整是否损坏
file /Applications/Steam++.app/Contents/MonoBundle/libonigwrap.dylib
正常应该输出类似 Mach-O 64-bit dynamically linked shared library x86_64
于是验证文件完整，输入
##1. 查看主程序如何引用 libonigwrap.dylib
otool -L /Applications/Steam++.app/Contents/MacOS/Steam++ | grep onig
##2. 查看 libonigwrap.dylib 自身的安装名称
otool -D /Applications/Steam++.app/Contents/MonoBundle/libonigwrap.dylib
##3. 查看 libonigwrap.dylib 依赖的其他库
otool -L /Applications/Steam++.app/Contents/MonoBundle/libonigwrap.dylib
##4. 检查主程序所有的 LC_LOAD_DYLIB 和 LC_RPATH 信息
otool -l /Applications/Steam++.app/Contents/MacOS/Steam++ | grep -E "(LC_LOAD_DYLIB|LC_RPATH)" -A2
从输出可以看到otool -L 显示主程序对 libonigwrap.dylib 的引用是 libonigwrap.dylib（没有路径前缀）。
而 otool -l 的输出显示，主程序有多个 LC_LOAD_DYLIB，其中一条是 name libonigwrap.dylib (offset 24)，确实没有 @rpath/ 或 @executable_path 前缀。
同时，输出中也显示了两个 LC_RPATH 条目，路径分别是 @executable_path/../MonoBundle/ 和 @executable_path/../MonoBundle（带和不带斜杠）。这两个路径都正确指向了 MonoBundle。
问题关键： 主程序对 libonigwrap.dylib 的加载命令是裸库名（无路径），而 dyld 对于这种裸库名，不会使用 @rpath。它只会搜索默认路径（如 /usr/lib、/usr/local/lib 等），而不会搜索 @rpath 指定的路径。这就是为什么即使添加了 rpath，dyld 仍然尝试空路径（即默认路径）而找不到。
解决方案：修改主程序对 libonigwrap.dylib 的加载命令，将其改为 @rpath/libonigwrap.dylib。
输入
install_name_tool -change libonigwrap.dylib @rpath/libonigwrap.dylib /Applications/Steam++.app/Contents/MacOS/Steam++
然后再重新签名（因为二进制被修改过）：
codesign --force --deep --sign - /Applications/Steam++.app
双击启动 Steam++，应该可以正常打开了
在 macOS 中，裸库名的查找规则是只在默认系统库路径（如 /usr/lib、/usr/local/lib）中搜索，而不会使用 @rpath 指定的路径（即使你已经添加了正确的 rpath）。
