SuperDisplay for Mac? Here's what exists.

SuperDisplay is a Windows app. If you have a Mac and a Galaxy with an S Pen, here's a fair look at the difference — and where PenCast fits (and where it doesn't). Facts checked 4 Oct 2026.

The short version

SuperDisplay is a Windows-only app. Its own help page lists a Mac port as "none planned for the time being" (checked 4 Oct 2026). So if you have a Mac and a Galaxy with an S Pen, you need a different tool.

PenCast is one option, but it works differently: it's a pen tablet, not a second screen. Your Mac screen stays the canvas, and your Galaxy is the surface you draw on. It won't show your canvas on the tablet.

Pick SuperDisplay if you're on Windows and want to draw directly on the picture on your tablet.
Pick PenCast if you use a Mac, or you're happy to look at your monitor while drawing on a tablet — like a classic pen tablet — and want a free tier and no ads.

Honest limits

Your tablet won't show your canvas. PenCast is a pen tablet, not a screen mirror: you look at your computer and draw on your Galaxy.
WiFi mode isn't encrypted yet. Use USB, Bluetooth (Pro) or a network you trust.
Installers aren't signed yet. The Mac app isn't notarized and the Windows installer isn't code-signed, so each asks for one extra click.
Apps differ. Compatibility depends on your drawing app and its pen settings. I haven't published a tested-apps list yet — try the free version first and tell me what works.
The Android app is coming to Google Play. The desktop app pairs with it; until it's live there's nothing to pair with.

Questions

Is there an official SuperDisplay for Mac?

Not as of 4 Oct 2026. SuperDisplay's own FAQ says ports to Linux, Mac OS or Windows tablets are "not completely out of the question, but none are planned for the time being." Check its help page for updates.

Is PenCast the same kind of app as SuperDisplay?

No. SuperDisplay turns your Android device into a second display plus pen input (it streams your Windows screen to the device). PenCast is a pen tablet: it sends only pen data to your computer and does not show your canvas on the tablet.

Which should I pick?

If you're on Windows and want to see and draw directly on the picture on your tablet, SuperDisplay is built for that. If you're on a Mac, or want a light pen tablet with no screen mirroring, no ads and a pay-once Pro, PenCast is built for that.

Which Mac alternatives exist besides PenCast?

Options I found on 4 Oct 2026: Duet Display (Mac and Windows, screen mirroring/pen display), Tab Display (Android as a Mac monitor, free with ads), Weylus (open source, browser-based), Tuval (early version for macOS/Linux/Windows), and a spacedesk Mac driver beta announced in September 2026. Features and prices change, so check each product's own page.
