MacMini M1 2020 doesn't work with wired Apple A1243 keyboard

My A1243 keyboard became very intermittent after 11.2 update when plugged into standard USB on Mac Mini M1, and acts the same when plugged in via powered USB hubs. Surprisingly, it works fine when plugged into LG monitor that is connected to mini via Thunderbolt 3.0/display port. This very frustrating, I had been successfully using this keyboard for about a month before it started flaking out.

MacOs 11.2 - Wired cheap chinese keyboard acts as if it is wireless since a few days, losing connection every 3 to 5 seconds for 3 minutes, then it is over for 15 minutes and it repeats again. OK, i got a lot usb hubs all with power, but I am longing for my already sold 2018 mac mini with the Logitech Master MX 2s, never had a problem.

Hi, I finaly get my Mac mini M1 and apple keyboard A1243 is working flawlesly, also the USB ports on keyboard working also.

No problem with that keyboard. It was working on 11.1 as I setup mini and after update to 11.2 it is also workig.

I have a Belkin USB-C multimedia hub that worked occasionally with my Apple A1234 USB keyboard. After latest update it won’t work at all. I was forced into buying an Apple pass-through adapter and everything now works, every time. But I wasted over $100 bucks on the Belkin that has more ports. And I really wanted the second USB port.

From the first day I use this old keyboard without any problems at all, i use both usb on keyboard and even plug old philips dvd external recorder to this keyboard and successfully burned several dvd-s. It is pluged without any adapters directly on mac mini m1. Also have magic mouse first generation and he is also working without any problems at at all. I also tryed to pair logitech mouse on bluetooth and worked with it several days without any issues at all. Monitor is dell s2721d and it is also working witout any display issues other have and wakes from sleep like imac-s do every time on mouse or keyboard. Final cut works withot any problems or audio dropouts. I connected crucial x8 1tb external drive and no problems at all. Am I just lucky or I dont know but from first day mini is working without any problems.

I am on 11.2.1 and keyborad is working fine without any issues on typing or usb ports. Also buyed apple magic trackpad first gen and paired it and it is working without any glitches or hickups with magic mouse first gen on bluetooth. Tryed to pair bluetooth headset and not problems at all working all together.

A1243 keyboard doesn't work at all unless passed through a hub.

From your description this is most likely a voltage issue at the USB port. Try using a quality powered hub to get around this.

Some people are fixed this issue with extension keyboard cable on older mac-s as this keyboard was not recognized by mac. I have the same keyboard and I can run DVD burner trough keyboard usb so I think mini has good voltage on this ports. Also connecting old hdd enclosures and USB sticks are working normally trough keyboard USB ports without any hub. If someone has problems with this old keyboards just sell it and buy new

Having the exact same issue as you on a brand new M1 Mac mini 16GB. I twisted my parents arms to upgrade their 2012 Mac mini so they’d continue to receive software/security updates, and this machine has been nothing short of torture for them. I should note that this keyboard is working perfectly fine on my mid-2015 MBP and my 16” MBP via USB-C adapter. This should be fixable in software, but this issue really needs to be escalated up the chain to make sure Apple is aware of what’s happening here. There’s no reason a USB HID device with a built-in hub should be flaky on a new machine.

Updated today and keyboard is working like before. I had a strange situation yesterday when I resteted the bluetooth module, after restart the keyboard does not respond on password screen but after connecting the mouse to usb hub on keyboard mouse moved but then suddenly disconnect and reconnect but I cannot type because the keyboard does not respond. After I disconnect the mouse the keyboard is recognized and then it worked like before.

I do not recommend doing the bluetooth reset because when you dont have mouse laging with bluetooth you will have it after the reset! My mouse then laging when i click on audio button on menu bar and in music app for about 6 sec and then works like normal. But it starts laging again when I click again on audio button in menu bar or open music app after quiting it.

I manage this problem disconnecting my usb 3.0 hub and shuttdow mac and pluged it out for 15sec then plug it back in and wait another 10 sec and then power it on. After all that procedure it now works like before without any laging or keyboard issues.

All in all, the Mac Mini is not as reliable as my Mini 2018. Now i have sudden spontanious restarts (4 times already), usb problems with keyboard and mouse, bluetooth problems with mouse and even a wired mouse act as a wireles mouse .... I wonder if that all can be fixed with updates.

I think it is not mac mini hardware that has problems, i think it is software related. I have conected monitor over hdmi and it has audio trough hdmi but sometimes it is not shown on menu bar when you click on audio button but it is showing in system preferences under sound. I thing apple did not polish big sur release for new chip.

Having the same issue and I'm signed up for the beta testing with Apple. I've had these issues intermittently. On a good USB hub switch that is powered. It doesn't matter if is powered or not some times it works and some time not. I'm typing right now on the via the hub with it unpowered and with a 2.4Ghz wireless mouse plugged into the A1243 usb slot and working fine at the moment. I've report to Apple via beta feedback -hopefully it will be fixed.

My Logitech Master S2 wireless mouse has never worked on the M1.

This is not an Apple issue. It's an Logitech issue. They have announced that they are no longer going to support Big Sur.

I believe Logitech Options has replaced Logitech Control Center.

My Logitech MX Master 2S works perfectly under Big Sur using Logitech Options.
