For Objective-See LuLu, consider implementing full inspection of Universal/fat binaries to prevent evasion of code signing checks. For Objective-See TaskExplorer, consider implementing full inspection of Universal/fat binaries to prevent evasion of code signing checks. For Objective-See WhatsYourSign, consider implementing full inspection of Universal/fat binaries to prevent evasion of code signing checks. For Objective-See procInfo, consider implementing full inspection of Universal/fat binaries to prevent evasion of code signing checks.
