To use Deep Data Recovery for Mac to retrieve lost files on a Mac with M1 or M2 chip, you'll need to enable system extensions in the Recovery environment. Save your work, shut down your Mac, and press the Touch ID or Power button while booting to enter Recovery mode. From there, select Utilities, then Startup Security Utilities, and choose the drive where Deep Data Recovery is installed. Select Reduced Security, allow kernel extensions from identified developers, and restart your Mac. After restarting, run Deep Data Recovery, and it will prompt you to allow kernel extensions. Click Allow, restart your Mac again, and you'll be able to use the software to retrieve lost files. If you have any further questions, contact Qiling Technical Support at support@idiskhome.com.
