Anyone purchasing an Accusys DAS solution at this time must follow the procedure outlined in these links:


Configure Mac Security Policy


Since Apple deprecated the use of Kernel Extensions (kexts), it is now necessary to alter the factory set Security Policy on all T2-based and M1-based Macs. This process is valid for all T2 and M1 based Macs running macOS Catalina (10.15.x) and higher, macOS Big Sur, (11.x).


For Intel-based T2-enabled Macs:

For Apple Silicon (ARM / M1) Macs:

Only once the steps above have been completed should you move on to the Accusys software/driver installation instructions. Skipping the steps above will result in an inability to complete the Accusys installation.


Accusys Software/Drive Installation


Download the latest version of the Accusys Installer from:

https://www.accusys.com.tw/Support/Download/

Follow the folder structure for the Gamma Carry: Download_file > Gamma > GammaCarry > Installer Package > Mac Installer > (For Intel Macs): Accusys_IP_Mac_x.x.x.zip, (For M1 Macs): Accusys_IP_Mac_x.x.x_M1.zip


Extract the downloaded ZIP file by double-clicking it.


Double-click the installer package (Accusys_IP_Mac_x.x.x.mpkg), you will see a dialog warning you that the package "cannot be opened because it is from an unidentified developer."

Click the "OK" button, then open System Preferences > Security & Privacy preference pane, select the General tab

In order to run the installation, click on the Open Anyway button, this will cause macOS to display a further confirmation/warning dialog

You'll have to click Open in order to successfully launch the Installer utility and complete the software/driver installation

Now walk through the installer as normal, accepting the default options

Upon completion of the installation you will be requested to Restart your Mac. Once restarted your GammaCarry should either mount and be available for use, or if requested the disk will be available in Disk Utility to be formatted ready for use.
