Sequoia Problem: Logitech wireless keyboard and mouse via KVM not working M1 Mac Mini

Here's my setup:


M1 Mac Mini

TESmart Dual Monitor KVM

Logitech Keyboard: Ergo K860, Logitech Mouse: M525

-- Both connected using Logitech Receiver in the KVM


I have been using this setup for years, with the Logitech USB receiver plugged into the keyboard/mouse port of the KVM switch. Works great switching between my MacBook Pro and my M1 Mac Mini.


Yesterday, I installed Sequoia on my Mini, and now when I switch back to the M1, the keyboard/mouse are unrecognized and I cannot access the Mini.


A couple of times a forced hard reboot of the Mini (via the power switch) will get the Mini to see the keyboard/mouse, but not all the time. I'm stuck having to shutdown the Mini, detach a USB device to free up a direct port, then move the Logitech Receiver directly into the Mini, and THEN it will see the keyboard.


Bug in Sequoia?

Mac mini, macOS 15.0

You have to reach out to TESmart technical support. They have a firmware binary but they have to give it you. It's not available for public download without their assistance. Makes sense, because if someone puts the wrong firmware on the wrong device it will break the device.

Fill out the form and submit.


At the bottom of the page is their phone number in China. You could call if you had to.

Confirmed @james brickley post worked for me.


I had just upgraded to 15.1 sequoia and this issue happend to me. Before upgrading my set up was 2 MacBook Pros on Sonoma.


Then I reached out to TESmart team, and they gave me a hex file, and a .exe tool to update the kvm. They gave steps on the email, and a video demo. It was pretty easy to follow, and I was able to get it working again.


Attached is the link to download the TESmart software tool. However, for the hex file, you will need to reach out to them.
