This is why the XML parser fails to read it, as it expects an XML format. Unity's build process and the code attempting to parse the Info.plist might not be equipped to handle binary plist formats directly, hence the error. To resolve this issue, you will need to convert the binary plist file to an XML format that Unity and its XML parser can understand. macOS provides a command-line tool called plutil that can convert binary plist files to XML format. if facing this issue, do the following: in Terminal, run : plutil -convert xml1 YOUR_PROJECT_FOLDER/Library/PackageCache/com.meta.xr.sdk.audio@60.0.0/Runtime/Plugins/MetaXRAudioUnity.bundle/Contents/Info.plist Now builds sucessfully.
