Other crosshair programs offer a single style or color option, and often don’t allow you to reposition them. CrossOver is a small, unintrusive crosshair overlay which has plenty of configuration options to assist with aiming and vision of your crosshair. CrossOver offers a huge improvement to many games’ default crosshairs for those with colorblindness or contrast issues.

Thanks to Reddit user /u/IrisFlame for the premade library of crosshairs!


macOS 10.10+, Linux, and Windows 7+ are supported.

Download the latest version of CrossOver from the releases page

Because this app is Free and Open-Source, we cannot afford to sign our code. This means Chrome may warn about an untrusted download, this is normal. Click the arrow icon -> Keep to finish downloading. Windows Defender and Mac Gatekeeper will prevent you from running the app the first time.

Download the .exe file. (CrossOver-Setup-x.x.x.exe)

Windows protected your PC.


Download the .dmg file. (CrossOver-x.x.x.dmg)

“CrossOver” cannot be opened because the developer cannot be verified.

“CrossOver is damaged and can’t be opened…”

M1 Mac security fix: (thanks Yoyopizzacat, #207)


Download the file appropriate to your system. (.AppImage, .apk, .deb, .freebsd, .pacman, .rpm, .snap)

The AppImage needs to be made executable after download.

Certain lightweight desktop environments may require a compositor to allow CrossOver to work correctly (#230).

Further instructions for Windows and Mac


❌ marks the spot…

Position: Click and drag the crosshair to anywhere on any screen. Double-click the bullseye to center the app.

Choose Crosshair: Click the bullseye ◎ to select from tons of preloaded crosshairs. Drag an image to the window to use your own custom crosshair.

Customize settings using the “gear” icon. See Settings below.

Unlock the app to quit using Control-Alt-Shift-X, then click the close icon in the top-left corner. In Windows you can right-click on the crosshair window > Close.

Default Keyboard Shortcuts

Description Keys
Toggle the settings window and lock the crosshair in place Control-Alt-Shift-X
Move the crosshair a single pixel Control-Alt-Shift-Arrows
Quickly hide/show the application Control-Alt-Shift-H
Center the crosshair window Control-Alt-Shift-C
Move the crosshair to the next connected display Control-Alt-Shift-M
Duplicate your crosshair in a shadow window Control-Alt-Shift-D
Display the “About” window details Control-Alt-Shift-A
Reset all settings and center the window Control-Alt-Shift-R
Mac: the Option key is used instead of Alt.
Linux: Some distributions do not center on double-click.



Choose from over 100 real and fictional crosshairs, or use your own by dragging an image to the window. You can change the size and opacity.


The reticle is the small dot or cross at the center of the sight. You can select the shape and the color, or this can be turned off.

Hide on ADS

Choose a mouse button to use as your ADS button. The crosshair will be hidden while this button is held down.

Harware acceleration

A handful of users have reported FPS issues with certain games (#70), CrossOver should not add any FPS or latency so if you experience it, toggle this setting on or off and disable Hide on ADS

Start on boot

You can automatically set CrossOver to start when your system starts on your gaming PC, so you’re always ready to pop heads.

Automatic Updates

By default CrossOver will automatically keep itself updated with bug fixes and improvements. You can disable this in the settings to prevent all network requests. CrossOver will only connect to GitHub to download published releases and does not send or store any personal data. I’m a solo developer and you aren’t important to me 🙂 I just want to game.


See default keyboard shortcuts. All of the keybinds can be changed or disabled except for the bind to reset all settings. Click into the input and press your bind, or press Backspace or Delete to disable a bind.

Keep in mind that keybinds may conflict with other programs so be careful about what you choose. There’s no real mechanism for preventing you from setting two conflicting keyinds within the app, so don’t do that.

Duplicate crosshairs

Duplicate crosshair windows use the same settings as the main window and do not support all of the features of the main window. Settings for duplicate crosshairs will not be saved and all duplicate windows will be closed if the main window is closed. Duplicate crosshairs cannot follow the mouse.


To reset all settings and binds to default, press Control-Alt-Shift-R

Built with Electron. Simple HTML and Javascript, no framework.

Start developing in src/main.js and src/renderer.js. index.html contains the layout and index.scss contains the styles for the main app BrowserWindow


You will need node.js v14.x.x installed. If you have nvm installed, run nvm install && nvm use to switch to the correct node version.
$ yarn && yarn start


Build steps optimized for Mac, see electron.builder for help customizing builds.

wine and mono must be installed for Windows builds (macOS) multipass must be installed for Snap builds (macOS)

$ yarn build

Or yarn build:all

Build issues

Test CI builds on Mac and PC before releasing

'CrossOver' is damaged and can't be opened.

CI builds do not seem to work correctly for Mac. Try using a real Mac to build.

Test closing via the traffic lights on Mac

Calling process.exit() before the app is done “quitting” will cause the app to crash on Mac.

i386 architecture deprecated in MacOS

Newer versions of OSX cannot build for 32-bit apps, use CircleCI to build those.

gyp: name 'openssl_fips' is not defined while evaluating condition 'openssl_fips != ""' in binding.gyp while trying to load binding.gyp


Using Node@16 worked.

To build rpm, executable rpmbuild is required, please install: brew install rpm

Continuous Integration (CI)

We use GitHub Actions, CircleCI and Appveyor to build and test CrossOver on every commit. Circle and GitHub build for all targets, Appveyor builds for Windows.

CircleCI builds are published to the Snap Store and GitHub Releases while Appveyor builds are published to the Windows App Store.

CircleCI needs the following environment variables:

As of v7, use the SNAPCRAFT_STORE_CREDENTIALS environment variable instead of the following

To install snapcraft on a Mac:


$ yarn release

Then edit the automatically created GitHub Releases draft and publish.


Hidden by fullscreen apps

Currently CrossOver only works with windowed applications, use Windowed Fullscreen mode if your game or application supports it. (Windows)

Fullscreen for MacOS may have better results.

Workaround using AutoHotKey (Windows)

via @girkovarpa

If you absolutely need to use Fullscreen mode, or your game is not supported by crossover, there is a workaround using AutoHotKey.

Doesn’t work with some games #47, and causes FPS issues in other cases

Install AutoHotKey and run this script with it (save it as script.ahk and double-click it):

Home::Winset, Alwaysontop, , CrossOver

Once in-game, pressing space should put the crosshair over the screen, even in fullscreen mode.

Performance Issues

There are reports of stuttering when using V-SYNC, G-SYNC, or similar Adaptive Sync (#330). Disabling these may improve performance. s

Graphical issues on Linux

Check your desktop environment. CrossOver may not work on KDE, try GNOME if you experience issues.

CrossOver behaves weirdly if your desktop is missing a compositor (#230). Try installing one to see if that resolves the issue.

Hidden by fullscreen apps on Linux

Some compositors, such as KDE Plasma’s KWin, can’t keep a window (CrossOver) over a full-screen window, so in such cases another compositor needs to be run that has this option.

GNOME’s Mutter is one of those compositors that can do this.

In Lutris, for example, this can be automated with shell scripts that will run when the game is launched and quit.

Lutris->Right click on game’s banner->Configure->System options:

Pre-launch script: /path/to/

mutter --replace # or: gnome-shell --replace

Post-launch script: /path/to/

kwin_x11 --replace
plasmashell --replace


You can run CrossOver from the command line to see debug output. Open a terminal and navigate to the CrossOver app, run ./CrossOver to see output:

(Mac, Linux)

╭─  lacymorrow in /Applications/ using
╰─○ $ ./CrossOver --debug
09:45:16.023 › CrossOver 2.7.4 Development
09:45:16.030 › Setting: Enable GPU
09:45:16.487 › App ready

Command-line lags


alias -d

Start CrossOver in debug mode, with Chrome DevTools open.


alias -r

Reset all app preferences to default, in case you get into a broken state.


alias -v

Print the app version to stdout (Good for CI).


An extra big thanks to the crosshair providers, as this wouldn’t be possible without them:
