General troubleshooting tips

If you have a problem with KeyCue, we suggest that you first try the following steps:

  • Make sure you have the latest version of Mac OS X and all system updates: Launch "App Store" and install all available updates. If you need to restart your Mac after the update, repeat this step until no further updates are available.
  • Verify that you are using the most recent version of KeyCue. Check the "About KeyCue" tab in KeyCue's Settings window and click the "Now" button to perform an immediate online check for a newer version.
  • If there is a problem with KeyCue in combination with a particular application, make sure you have the latest version of that application. If you have a problem with any part of MS Office, run Microsoft AutoUpdate to install the latest updates.
  • Restart your Mac (unless you already did that during the software update).

In many cases, these steps help to fix software-related problems. If this does not help, check if any of the following questions apply to your problem. If not, contact our technical support for help.

Questions and answers

Is KeyCue compatible with macOS Mojave?

Yes, but you need KeyCue 9.1 or newer for full compatibility with Mojave, including support for dark mode. For more information, please see our compatibility page.

Why does KeyCue fail to work after upgrading to Mojave?

There is a bug in Mojave’s handling of application permissions, which can prevent some applications (such as KeyCue) to work properly. Follow the steps below to work around the problem:

  • Open System Preferences / Security & Privacy.
  • Click the Privacy tab and select “Accessibility” in the list to the left. KeyCue should be listed in the System Preferences window as shown in the picture below.
  • To make any changes, you will need to open the padlock at the bottom of the window (requires an administrator password).
  • First try turning KeyCue off and back on in the list. This already helped for some users.
  • If toggling the checkbox did not help, select KeyCue in the list and click the “–“ button to remove KeyCue.
  • Click the “+” button and select KeyCue from the Applications folder to add it back to the list.

Accessibility MojaveKeyCue will appear in the list with the checkbox turned on as shown in the picture to the right. From now on, it should be back to normal.

If this does not help immediately, restart your computer.

Hint: This trick may also work for other applications that do not work as expected.

Is KeyCue compatible with macOS High Sierra?

Yes, but you need KeyCue 8.5 or newer for macOS High Sierra. For more information, please see our compatibility page.

Is KeyCue compatible with macOS Sierra?

Yes. We recommend using KeyCue 8.4 or newer for macOS Sierra. For more information, please see our compatibility page.

Is KeyCue compatible with older system versions?

Yes, we take special care not to leave our long-time users behind. The latest version of KeyCue is compatible with El Capitan, Yosemite, Mavericks, and even OS X versions back to 10.6. For more information, please see our compatibility page.

Pressing the command key just brings up a message telling me that I need to change a setting before I can use KeyCue. Why?

OS X contains an option that allows utility applications like KeyCue to interact with your computer on your behalf. By default, this option is disabled, so you need to turn it on. KeyCue can help you with this: The message window contains a button that opens System Preferences and selects the pane that contains the required option. The actual result depends on the current version of OS X. On Mavericks and newer (including Yosemite), enable KeyCue in the “Accessibility” section; on older versions of OS X, activate the option "Enable access for assistive devices".

Why do some menu titles appear blank?

Some menus appear with an icon instead of text in the menu bar. For example, the script menus of some applications have a script icon as the menu title. KeyCue currently cannot display the proper symbols and shows a blank menu header instead.

Can I use KeyCue to type command-"]" on a German keyboard?

You cannot. Unfortunately, some applications have shortcuts that will work only with a US keyboard. The problem is that the developers of these applications did not consider that keyboards for other languages may have other layouts and symbols.

For example, a German keyboard does not have keys labeled with “[” and “]”. If an application uses these characters for menu shortcuts (such as command-"]”), KeyCue will include them in the shortcut table, although you cannot type these shortcuts.

However, you can activate all shortcuts by clicking – even those you cannot type.

Can I use KeyCue to define my own shortcuts for menu items that do not have shortcuts?

No, but you can do that with System Preferences -> Keyboard: Click the "Shortcuts" tab and define your own shortcuts.

How can I change my preferences for KeyCue?

When the shortcut table is currently visible, type the "KeyCue Settings" shortcut at the end of the list or click this item. If this does not work, locate the KeyCue application icon in the Finder and double-click it. This will launch KeyCue if it is not yet running; the KeyCue icon will briefly appear on the screen. When KeyCue was already active in the background, double-clicking its icon opens the settings window instead. With KeyCue 8.0 or newer, you can also define a custom trigger for quickly opening the settings window.


With KeyCue 8.0 or newer, you can also define a custom trigger fro quickly opening the settings window.

The "KeyCue Settings" shortcut does not work. Why?

By default, KeyCue uses command-option-K as the shortcut for opening the Settings window, but this shortcut is active only as long as the shortcut table is visible on the screen. The reason for this is that KeyCue switches to a different shortcut when command-option-K is already in use by the current application. To see which shortcut opens the Settings window, you therefore must open the shortcut table and type the "KeyCue Settings" shortcut while the shortcut table is visible.

What is the best procedure to install or update KeyCue?

KeyCue uses a "smart self installation" technique that makes installing and updating a breeze. Just mount the downloaded disk image and double-click the KeyCue icon inside. KeyCue will quit an older copy that may be running, copy itself to the Applications folder and launch the newly installed copy. There is no magic involved: You could do all this by hand as well; KeyCue just simplifies and automates the process and gets you up and running in seconds.
