Make sure to issue the following command, otherwise ibtool will likely fail during build: sudo xcode-select -s /Applications/Xcode.app/Contents/Developer I’ve successfully built the latest Dolphin with these steps.įirst, make sure that you have Xcode installed (free download from the AppStore) and have Xcode command line tools installed: xcode-select -install There are many ways to do this, but for me none of them worked as most of the time I simply ended up with an app bundle that crashes on start.
