Hi there, I've found an issue with the xcode project compiling for mac. Here are the details (I've submitted a repro project for this, issue id: 1276317): Please note this is not a duplicate bug report either. It's a development on a previous issue that was reported as fixed in 2019.4.8 Steps: 1. Create a new project in 2019.4.9, the only modification I've done is to add a plugin .bundle for Mac 2. In Build Settings make sure the standalone mac platform is active, enable Create Xcode Project and Build out an xcode project 3. Trying to then compile results in code sign error: CodeSign /Users/jason/Library/Developer/Xcode/DerivedData/MacXcode-ddporllwmsqitcfnqhidpczffuop/Build/Intermediates.noindex/ArchiveIntermediates/MacXcode/InstallationBuildProductsLocation/Applications/MacXcode.app/Contents/PlugIns cd /Users/jason/Desktop/MacXcode/Build export CODESIGN_ALLOCATE=/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/codesign_allocate Signing Identity: "-" /usr/bin/codesign --force --sign - --preserve-metadata=identifier,entitlements,flags --timestamp=none /Users/jason/Library/Developer/Xcode/DerivedData/MacXcode-ddporllwmsqitcfnqhidpczffuop/Build/Intermediates.noindex/ArchiveIntermediates/MacXcode/InstallationBuildProductsLocation/Applications/MacXcode.app/Contents/PlugIns A copy files phase was added for the Plugins in 2019.4.8, but this change is not sufficient at adding bundle plugins into a generated xcode project despite this issue being declared as fixed: https://issuetracker.unity3d.com/issues/macos-bundle-plugins-are-not-linked-on-xcode-project-export This is the result from 2019.4.8: https://www.dropbox.com/s/6fru063gzat5mny/MacCompileError1.png?dl=0 But this is the result that it should be which matches the xcode projects generated in iOS and allows bundles to be correctly signed: https://www.dropbox.com/s/n75h69p32zkryq9/MacCompileError2.png?dl=0 Note that the correct copy phase is set to PlugIns and has 'Code Sign on Copy' enabled per bundle. The copy phase set to Wrapper that was added in 2019.4.8 does not allow this setting to be set on the static plugins folder and makes it impossible to compile at the moment using the mac Xcode project option. The change that addds a static plugins copy phase needs to be removed again is not correct. The solution for this should match what iOS project creation does. We have taken a copy of the PBXProject api and modified this to properly add the bundles, please reach out if it would help to get a copy of how we did this if it speeds up implementation, but as it stand this is the single biggest blocker for Unity developers that want to use the Xcode project option for Mac and because it's a extremely technical process to modify the PBXProject properly many developers we know have given up on trying to use the xcode project for mac option because of this.
