Thanks for joining SSD community.
I understand you are trying to update SSD firmware using a Mac Mini computer.
This is definitely an issue with your computer model. If your computer does not detect USB keyboard then I recommend updating SSD firmware using another computer with USB 3.0 support.
A new version of the Firmware Update Tool (FUT) is finally available. You can download it at:
This version of the tool resolves issues with the Mac Mini USB keyboard and mouse.
I want to be clear that this is really only a change to the FUT tool itself. I can't say that this will address the reports of periodic high activity or slow response on these systems.
We have not been able to find satisfactory solutions to these reported issues.
I can confirm the keyboard, and mouse are functional on the Apple Mac with USB 3.0 ports.
The firmware is able to fully access the intel SSD hard drive installed.
Thanks for the update!
