@ahmedmohammed See this guide on software repair using PC Companion.

Android Device Manager is only able to reset screen lock patterns for device's running Android 4.4 or below, this is mentioned on Google's Help site for Android.

In this case you will unfortunately have to use PC Companion or Bridge for Mac to perform a software repair using PC Companion as @uliwooly and @alexdon mentioned.

Connect your device to PC Companion & reset your lock screen...
