The Apple Magic Mouse has never worked on the login screen on iMac 2017 in OS Catalina. For example if there is more than one user (which luckily there isn't most of the time) you cannot choose which user, or you cannot choose to shut down. Also Magic keyboard has delay when starting to type password. Seems like the mouse does not connect to Bluetooth before logged in to an account and the keyboard doesn't connect right away.
The following will require any USB keyboard and mouse. If you don’t have them, borrow or buy them, they are inexpensive!
1. Connect the USB keyboard and mouse to the computer.
2. Open System Preferences – Bluetooth
3. Un-pair the wireless keyboard and mouse.
4. Turn off Bluetooth
5. Restart the computer in Safe Mode per the directions in https://support.apple.com/en-us/HT201262
6. Restart the computer normally.
7. Open System Preferences – Bluetooth
8. Turn on Bluetooth
9. Re-Pair the wireless keyboard and mouse.
10. Unplug the USB keyboard and mouse and begin testing the wireless devices again.
What is EtreCheck? I googled it but not sure if I got what you meant. Is it Canadian?
Do you need the actual text?
I need to be able to read the complete report in order to be of any value.
OWC RAM is high quality assuming you bought it directly from OWC. Yes, I would recommend physically removing it to test it.
Hi,
I reinstalled the Catalina OS today, but it did NOT solve the problem of the wireless mouse not working on login page. I've enclosed new etrecheck report. Thanks!
This is one of the first things I did, but it did not help.
You followed those EXACT steps, if you did not, please do.
Yes the EXACT instructions, and I just did it again with the reinstalled Catalina. No help.
(By the way the mouse works perfectly on login screen on an older iMac running High Sierra!)
All of a sudden, today it is working!!!!! I didn't even see this suggestion until just now, but apparently didn't need to do it. Thank goodness. Thanks for all your help.
Actually, I spoke too soon. Some of the time it works, not all.
