Let your Android / HarmonyOS tablet be a smooth second display at up to 120Hz and 10-bit HDR — and drive your Mac from it. Plug the cable in and it runs: no developer settings to switch on, no ADB to install. Wi-Fi works too.
Open test — anyone can install it, and it’s free during the test. Start from the Download section.
Hardware makers’ own second-screen features stay inside their own ecosystems — each one works only with that maker’s devices.
For someone holding a Mac and an Android / HarmonyOS tablet, none of them applies. Codeyzer Screen was written for exactly that gap.
It uses the whole panel you already own, sets up by plugging in a cable, and lets you drive the Mac from over there.
Hardware-accelerated HEVC at up to 2.8K, 120Hz and 10-bit HDR color — as far as your panel goes.
Setup is plugging in a cable: no Developer Options to enable, no ADB to install, no menus to dig through.
The tablet does more than receive a picture. Touchpad, keyboard, your finger and your pen all land on the Mac.
All of it is shipping and verified on real devices.
The tablet attaches as a virtual display, so it doesn’t count toward your Mac’s external monitor limit. Even on a MacBook that supports one monitor, it is added next to it.
Your Mac’s audio goes to the tablet; each tablet shows up as its own output device in macOS, and the volume can be set from the tablet too.
The stream comes up even when the tablet is on mobile data or another Wi-Fi — through your own Tailscale account. Smoothness depends on the link in between.
More than one tablet can attach to the same Mac — each as an independent display, with its preferences stored on that device.
Turn the tablet and the stream rotates to portrait without dropping. Ideal for reading code and documents.
The stream keeps running while the Mac is locked or its lid is shut; wake it from the tablet and carry on where you left off.
The Mac pointer extends one-to-one; relative mouse movement works in games, and when the Mac hides the cursor it is hidden on the tablet too.
Pin the tablet to the stream while it runs — one click from the Mac when you step away from the desk.
No account, no analytics, no tracking SDK. The picture flows straight between your Mac and your tablet.
The same app, three different desks.
Put the tablet next to your MacBook: docs, terminal and messages live there while the main screen stays on the work. Since the tablet is outside the external monitor limit, it is added even when a monitor is already attached.
Put the desktop Mac on the network and run it from the tablet — screen, touchpad and keyboard — without carrying a separate monitor, mouse or keyboard. It connects even while the Mac is locked.
Connect from the sofa, from another room or from the road. Turn the tablet into a portrait reading screen; away from home it works the same way through your own encrypted tunnel.
Codeyzer Screen is two apps: one on the Mac, one on the tablet.
Download the DMG, move Codeyzer Screen into your Applications folder and open it.
Join the open test on Google Play or Huawei AppGallery and install it.
Plug in the USB cable, or open both on the same Wi-Fi network — the tablet appears on the Mac as a new display.
On the first connection Codeyzer Screen measures the smoothest settings for your device and saves them; later sessions start straight from there.
Put your Mac mini or Studio on Ethernet and run it from the tablet — screen, touchpad and keyboard — without carrying a separate monitor, mouse or keyboard.
Install it on your computer and on your tablet, then connect over a USB cable (or on the same Wi-Fi).
Codeyzer Screen is two apps — Mac + tablet, and you need both. The tablet app is offered as an open test on Google Play and Huawei AppGallery — anyone can join, and it is free during the test.
