Option command does not work without Fn

lxdr wrote:

Whenever I want to use a keyboard shortcut that requires Option + Command (like Option + Command + V to paste a file) I also have to press the fn key. This is true for any shortcut using Option + Command in any app (for example Option + Command + R in JetBrains IntelliJ also requires using fn). How can I configure my system to not require the fn key anytime I want to use an Option + Command shortcut?

Thank you.

Old issue, new issue, what changed?

You can >System Preferences>Keyboard >Shortcuts, here you can "restore defaults" if there is a conflict.

if no resolve or insight—

Try resetting the SMC https://support.apple.com/en-us/HT201295

Try resetting NVRAM/PRAM http://support.apple.com/kb/ht1379

(get at least two-three rounds of the chimes when holding the NRAM Reset)

@leroydouglas it's a new computer. Been this way since I got it. I have another MacBook where this isn't an issue. I've tried restoring defaults for Keyboard > Shortcuts and there are no conflicts, but the problem persists. I'll try resetting the SMC and NVRMA/PRAM.

On a new purchase you have a limited 14-days for a full refund or exchange for one that works as expected out of the box.

After that if it is hardware issue—it falls under a warranty repair.

This catches my eye in your OP "JetBrains IntelliJ"... as a possible conflict(?)

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, does a 5 minute disk repair before it fully boots up, and certain system caches get cleared and rebuilt, including dynamic loader cache,  etc. 

Login and test. Reboot  as normal and test.  Caches get rebuilt automatically.

In Safe mode third party system modifications and system accelerations are disabled, it removes malware, etc hampering smooth operation, however a  reboot will put it back to normal mode.

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

 —Test issue in another user (or guest user) account https://support.apple.com/guide/mac-help/set-up-other-users-on-your-mac-mtusr001/mac

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

Uninstall all third party apps that are Cleaners/Optimizers/VPN/Anti-Virus
