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

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.

I have had the same issue since upgrading to macOS 15.0. Mine is a MacBookPro 2018 15-inch Intel chip. The mouse and keyboard are not recognized via the KVM switch (TESmart—2 Port Dual Monitor KVM Switch HDMI 4K60Hz with USB Hub) and docking station (Plugable 14-in-1 USB-C Triple Monitor Docking Station with 100W Charging - DisplayLink Dock with 3X HDMI, Compatible with Windows, Mac, Chromebooks (Replaced by UD-3900PDZ)).

Adding my voice to the chorus. The problem I experienced today 9/22/24 seems identical though I'm using different model keyboard and mouse. No problems before update for a year. Now the Tesmart KVM switch seems to be unable to share K and M with the M2 Mac mini I just updated to Sequoia 15. The keyboard and mouse and others work fine plugged in directly. And they work fine with the Dell laptop connected to the KVM. If anyone finds a fix, please post. Thanks

For those who are curious: I have installed the Sequoia 15.0.1 update and nothing’s changed for my logitech keyboard.

Take caution when upgrading with Tesmart firmware. As mentioned in an earlier post, Tesmart sent me the wrong firmware in the beginning (HKS0401A3U_KM_SOFMUS2_V008.bin) and the 2nd (HKS0403A1U_KM_-SOFMU16-V014.bin) made things worst. The most recent (HKS0403A1U(USB20)_KM_SOFMU16-V011-APP.bin) has station 1 in control regardless of what station is selected. I've requested the original firmware that was installed during release but they are reluctant to and now are trying to upsell me to a newer model for an exchange of my KVM and 40% discount on the newer.

I have the TESmart 3 monitor / 4 machine switch (HKS0403A1U - has USB2.0 (not 3.0)) and same problem now post Sequoia 15.1 install. I contacted TESmart and received the same firmware upgrade. However, the firmware update tool (exe) requires a Windows machine to run. I am running Parallels on my MAC Studio and run a Windows 11 VM. Unfortunately, this update tool doesn't work on VMs. TESmart is aware of this issue and verified it has to be a real Windows machine. I'm going to track that down and see it if works next.

Having the same issue with an M2 Studio and no recognition of the keyboard/mouse connected to the KVM switch after upgrading to Sequoia. They work with the other systems connected to the switch. Thought about rolling back to the old OS, and discovered the changes to Time Machine that now require wiping the drive and using Migration Assistant.

Similar issue where wired keyboard through TESmart KVM did not work on Mac Studio (M1 Max) side after upgrading from Sonoma to Sequoia. (Other side of KVM is an HP laptop and that worked fine.) I reverted to Sonoma from Sequoia on the Mac Studio via a Sonoma boot disk installer (with some bumps along the way). Mac Studio side works fine now on KVM, but running Sonoma, not Sequoia. Great solution for me until the issue is fixed in Sequoia.

Is there any way we can grab this online? I have this identical problem (TESmart KVM keyboard/mouse not recognized on Mac after upgrading to Sequoia) and I've contacted their support but haven't heard back and their website isn't helpful at all.

I'm having the same issue on my MBA M3. Logitech Pop Keys and Pebble Keys keyboards are not connecting no matter what I do and I managed to connect my mouse after minutes of trying. Before this MacBook I had MBA early 2020 i5 model and both of the keyboards and the mouse connected with no issues whatsoever. I updated that old MacBook too, it's on Sequoia now. I tried to connect my keyboards to this old one and they wouldn't connect. It was when I realized the issue was Sequoia and not my MBA M3. We are used to MacBooks being incompatible with some apps etc. but not the keyboards and mouses too now... I really hope that Apple does not leave this issue unsolved. I enjoyed using my keyboards and it's upsetting that I'm no longer to use accessories that I loved.

Update: I've been working with TESmart to resolve my issue. Sadly, the first firmware update they sent me was for the wrong model and obviously didn't work. The 2nd firmware update they sent me made things worse. I haven't heard back from them for a couple days now.

Same problem here with a MacBook Pro 14" M1 Pro 2021 and Sabrent USB C KVM Switch with dual HDMI outputs.

It was working well before the last update, but now when I switch from a Windows laptop to Mac it doesn't recognize the mouse or keyboard. I have it in clamshell mode and I need to open it an close it again to be able to work on it. I'm thinking on going back to the previous Mac OS version, this is pretty annoying.

I have the same problem. I can get keyboard and mouse to work on the mac mini if I plug them into a usb hub then plug it into the usb 2.0 port on the kvm, but they only work on the HP PC if they are plugged into the dedicated ports. I have the firmware upgrade from tesmart but I am a bit nervous about installing it especially since I have a work around. However, I would like to solve the problem. Am I better off waiting to see if Apple solves the problem or install the kvm firmware? Thoughts?

Update: TESmart provided me the orignial firmware (HKS0403A1U(USB20)_KM_SOFMU16-V009_BOOT_APP.bin) and an updated firmware (HKS0403A1U(USB20)_KM_SOFMU16-V011B-APP.bin). The newer firmware resolved my issue.
