Shift key not working while caps lock is on.

PSS Here is a link to download the "US with PC Shift" keyboard file. You put the .keylayout file in Library/Keyboard Layouts and then go to system preferences/keyboard/input sources and use the plus button to add it (it should be in the Others category), and then select it in the "flag" menu at the top right of the screen.

PS I gather using shift to produce lower case letters when caps lock is on is something you can do in Windows, but normally not in Mac. Is Windows what you are used to?

Someone made a custom layout to deal with this issue:

There is also an app called Karabiner which probably can do what you want.

As far as I can tell, "shift" has no function while caps-lock is on

With the US keyboard layout, when caps lock is on, shift just changes the number and punctuation keys to produce their upper case values (otherwise they remain as they were). Are you expecting to be able to type lower case letters? It never does that on my machine. Has it done so on yours in the past?

To trouble shoot further you can:

Try a SafeBoot https://support.apple.com/en-us/HT201262

Takes noticeable longer to get to the login screen as certain system caches, dynamic loader cache etc get cleared and

rebuilt. This test will tell you if third party inference; extensions etc are not loaded in safe boot mode.

Test issue in another user (or guest user) account https://support.apple.com/en-us/HT204443

This will tell you if it a universal issue or isolated to your user/admin account.

Just because it hasn't done so in the past, doesn't mean that's best. I'd prefer to be given the option to type in the same way that most of the world does.

In the meantime, try the custom layout I gave you link to.
