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

The new Mac mini M1 has two main issues currently, bluetooth and the USB port is not providing enough power.

Hopefully Apple will address these growing pains in the next update.

You should be able to get around the USB issue with an Apple USB-C to USB adapter (MJ1M2AM/A) or by using a high quality active USB hub (cheap simply hubs will not work).

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.

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

Purchased a Mac mini with Big Sur. First time I restarted from a shutdown it would not recognize either my Apple A1243 wired keyboard or my Apple bluetooth A1314 keyboard. I tried stopping and starting a couple times with no success. I removed power cable from the MacMini for a couple minutes and then plugged it back in. Started computer with the wired A1243 keyboard plugged into the Mac mini USB port and it worked as designed. Have received two system updates (currently 11.2.2) since purchasing the mini and each time I have to unplug the computer before a restart for the keyboard to be recognized. Not the most technical fix but "keeping it simple" worked this time. Apple needs to sort this.

It should work.... When your mini is off then plug the keyboard and mouse to usb ports without hub and then power on your mini... if the keyboard did not get recognized just instantly just tap a few keys and it should be recognized. After you do initial setup and all is working then connect your bluetooth peripherials but not to manny because you cann experience lagging. If you plug in some usb hubs on usb A connector just wait a little, it did not work just from the start, I think some drivers must be installed and mac is doing it in background. I have also a usb A 3.0 hub and it is working ok but my keyboard is connected strait to minis port the one that is at nearest to corner and it works.

I've had luck using a powered USB hub with the keyboard. Every once in a while it will have issues, unplugging/plugging USB connection to Mini sometimes corrects it.

I am on 11.2.1 and the issue remains for me, A1243 keyboard doesn't work at all unless passed through a hub.

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.

I've been having the same problems - A1243 keyboard was working with my M1 Mac Mini when plugged directly into the USB A socket.

Then today it completely stopped working through the USB A socket, but does work when plugged in to an adapter on the USB C one. Have upgraded to Big Sur 11.2.2. Made no difference and keyboard still didn't work when plugged into the USB A socket.

I've just run a 3rd party piece of software 'CleanMyMac' on the computer, and the keyboard is now working fine. Didn't read the report of what it did in detail but whatever it did seemed to make a difference.

At this moment buy a cheap chinese keyboard.

If you cann return this unit and get new one, maybe you have got faulty unit.

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.

On M1 Mac mini, Apple USB keyboard shows up only as "Keyboard Hub" in system report and keyboard doesn't work. Hub has works; connects to iPhone. Keyboard works on iMac in house. Cheap PC USB keyboard works fine on mini.

Have tried USB A and USB C hubs. Still only a Keyboard Hub.

My old wired apple extended keyboard worked fine on Mac Mini M1, but after update to macos 11.1 it stopped working. So now I am using a $10.- chinese keyboard, that works fine. My Logitech Master S2 wireless mouse has never worked on the M1.

Apple is becoming the greatest **** since it only should work with their own expensive ****. Firewire is no longer working unless you buy 2 expesive apple cable adapters $130.-, firewire to minidisplayport and minidisplayport to thunderbolt 3.0. USB 3.0 had a very late integration. USB C is not Apples Thunderbolt 3, so if don't buy the expensive apple cables you are in very deep ****. APPLE IS ****!!!

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
