Desktop Mac not recognizing any input devices

When I tried to start my Mac this morning, it wouldn't recognize my keyboard or mouse so I couldn't type in a password. I tried turning off then on. Now, my mac keeps flashing pictures of a mouse and keyboard showing how to turn them on; however, it still won't recognize any keyboard. I have tried the magic keyboard both bluetooth and via USB connect; still no luck.

I have a desktop Mac, but I am not sure which version.

Any ideas on how to get a mac to boot up if it won't take any inputs?

iMac Pro (2017)

What was on the screen before the alternating keyboard and mouse screen..?

Have you tried restarting the iMac..?

If the iMac seems frozen or unresponsive, press and hold the power button for 10 seconds or until it shuts down, then press the power button again to turn it back on.

Then if the keyboard and mouse fail to reconnect...?

When was the last time you recharged or replaced the batteries of the keyboard and the mouse?

If these have rechargeable non-removable batteries, plug the device into the computer by its USB port for 30 minutes or so. Then try again.

I had tried restarting my Mac a couple of times and that didn't seem to work. However, I tried it again and this time it worked (maybe I wasn't holding the power button down long enough?). Regardless, I am in, and my mouse and both keyboards are working fine.

Thank you for the reply.

The batteries were fully charged. I even tried connecting my magic keyboard directly to a USB port on my Mac, and that didn't work. However, I did finally get in. Thank you for taking the time to reply.
