Downloaded the Assistant from DJI.com for Mac.

As soon as the installer tries to open Apple chucks it out as it's from an unknown developer and may contain malware.

Any ideas ??

My mavic keeps warning me that my IMU / Camera needs attention through the assistant so it looks like I need it to work at some stage.

Hi there. Thank you for reaching out. The anti-virus software is reporting false positives. If the installation file is downloaded from the official website or obtained through regular channels, you can disable the anti-virus software on your PC to install the DJI Assistant 2 software. After the installation process is done, you can now enable the anti-virus again. Hope this helps. Thank you for your understanding and support.

You need to tell the MAC to allow apps from ALL developers/sources, and that should allow it to run the installer.
