JetBrains products not showing FN keys on touchbar

I wanted to list the simplest way I've found. It is based on Rob's related, helpful answer to this question, but I've tried to make it simpler and clearer, without unnecessary steps.

• Go to System Preferences > Keyboard > Shortcuts (tab).

• Click "Functions Keys" from the pane on the left.

• Click "+". A file picker will pop up.

• Select your application; e.g. CLion or IntelliJ.

That's it. Now, when you open up your application, you will see function keys in the touch bar.

JetBrains has implementation in IDE preferences to fix this. Open your IDE and go to

Preferences (⌘-,) > Keymap

Then check "Always show function keys (F1-F12) on the Touch Bar."

Restart the IDE and you should see function keys.

If you are using ToolBox App to install your JetBrains products then please have a look at the comments in IDEA-167332 ticket -- you will have to locate your apps in ~/Library/Application Support/JetBrains/Toolbox/apps/ folder.

Downside -- you need to repeat this to every new build of such app that you will install as the path to actual app will be different every time.

UPDATE: the aforementioned ticket has been marked as fixed for 2018.2.x version version. You now have an option on Preferences | Keymap screen.

By default it is not possible to select inside of an app folder. So in order to be able to get the function keys configured, follow the following steps:

go to: System preferences -> Keyboard -> Shortcuts -> Functions keys

Click the + icon

Then press CMD+SHIFT+G to open up a path window. Enter: ~/Library/Application Support/JetBrains/Toolbox/apps

Select the correct application and version to make the function keys work again.

Repeat for every application you use.
