Your desktop version installer is downloading!
Getting YuvinOS Desktop ready for your computer…
If you don't see it, click the download button next to this text.
Checking…once it lands
- Open the file you just downloaded.
- Drag YuvinOS Desktop into your Applications folder.
- Open it. The first time, macOS will warn you about the app — see below.
Neither is true. Apple only vouches for apps whose makers pay Apple for a developer certificate — Yuvin's Test Services is a free hobby project and doesn't — so macOS warns about this app exactly like it warns about many free and open-source apps. Two ways past it:
The quick way. Open Terminal, paste this line and press Return, then open the app normally:
xattr -dr com.apple.quarantine "/Applications/YuvinOS Desktop.app"
Or without Terminal. Try to open the app, click Done on the warning, then go to System Settings → Privacy & Security, scroll down to Security, and click Open Anyway next to YuvinOS Desktop.
- If Edge says the file "isn't commonly downloaded", click the ⋯ next to it → Keep → Show more → Keep anyway. (Chrome may ask you to Keep it too.)
- Open the installer you just downloaded (it's in your Downloads folder).
- Windows will probably show a blue box saying "Windows protected your PC". Click More info, then Run anyway.
- Follow the installer — Next, Install, Finish. YuvinOS Desktop then lives in your Start menu.
Got an ARM laptop, like a Snapdragon Surface? That needs a different build — get the ARM version here.
Microsoft SmartScreen warns about any app whose maker hasn't paid for a Microsoft code-signing certificate. Yuvin's Test Services is a free hobby project, so nearly every new free app you install looks exactly like this the first time — it isn't a sign that anything is wrong.
You'll only see it once. Updates install from inside the app, and Windows doesn't warn about those.
- Right-click the zip you just downloaded → Extract All… → Extract. Keep it somewhere permanent, like your Documents folder.
- Open the extracted folder and double-click YuvinOS Desktop.exe.
- Right-click it in the taskbar → Pin to taskbar so it's easy to find next time.
This is the version built for ARM laptops like Snapdragon Surfaces. Installers are unreliable on ARM Windows, so YuvinOS Desktop comes as a plain folder instead — it runs exactly the same, and updates still install themselves from inside the app.
Windows may warn you the first time you open it, because the app isn't signed with a paid certificate. Click More info → Run anyway; you'll only see it once.
- Open Terminal (press Ctrl + Alt + T) and type these two lines, pressing Enter after each. It will ask for your password — the letters stay invisible while you type, that's normal.
cd ~/Downloads
sudo apt install ./YuvinOS-Desktop.deb
Tip: type ./Yuv and press Tab — Terminal fills in the long filename for you.
- Open YuvinOS Desktop from your app menu.
Prefer clicking? You can also double-click the downloaded file to install it with App Center — but the Terminal way shows you exactly what's happening if anything goes wrong.
That's normal whenever you install a file from your own Downloads folder — apt's safety helper isn't allowed into personal folders, so it reads the file itself instead. Nothing is wrong.
App Center says "Potentially unsafe"?It says that about every app installed from outside App Center, and shows the publisher as "Unknown" for the same reason — it isn't a sign that anything is wrong.
Why does it ask for my password?Installing a system app on Linux always needs your administrator password — updates will ask for it too, once each time. That's normal.
Every YuvinOS Desktop download has a fingerprint (a SHA-256 checksum). If even one byte of the file were changed, the fingerprint would be completely different. Run this on your computer:
It should print exactly this fingerprint:
