Download Valo

macOS

Installing on a Mac

The disk image ships with a small helper called Open Valo. It exists because macOS stamps every downloaded app with a hidden “came from the internet” mark, and on an unsigned app that mark produces the damaged message — which on recent macOS has no Open Anyway button at all. The helper removes the stamp and re-signs Valo on the spot. It never asks for your password.

1. 1

   Open the downloaded .dmg file

   A window opens with the Valo app, an Applications shortcut, and the Open Valo helper.
2. 2

   Drag Valo onto the Applications folder

   Same as installing any Mac app. Wait for the copy to finish.
3. 3

   Double-click “Open Valo” in that same window

   Not the Valo app itself — the helper. It cleans up the download mark, re-signs Valo, and launches it.
4. 4

   If macOS blocks the helper too, right-click it and choose Open

   Right-click (or Control-click) Open Valo → Open → Open again in the dialog. On macOS Sequoia and later you may instead need System Settings → Privacy & Security, scroll to the bottom, and click Open Anyway.
5. 5

   That’s it — Valo opens

   From now on launch Valo normally, from Applications or Spotlight. You will not need the helper again; updates repair the signature themselves.

Windows

Installing on Windows

One installer, no choices to make. It installs into your own user folder, so Windows does not ask for an administrator password.

1. 1

   Run the downloaded installer

   The file is named Valo-Setup-1.2.53.exe.
2. 2

   A blue window appears saying “Windows protected your PC”

   This is SmartScreen. It is the unknown-publisher warning described above, not a virus alert.
3. 3

   Click “More info”, then “Run anyway”

   More info is small text under the message. Clicking it reveals the Run anyway button. Without that first click there is no way forward — which is exactly where most people give up.
4. 4

   Valo installs and opens itself

   No restart needed. If your antivirus quarantines the file instead, verify the checksum below and then allow it — antivirus tools frequently flag unsigned installers by default.

Linux

Installing on Linux

Debian and Ubuntu (64-bit) have a package. Fedora and Arch are not built yet — if you want one, say so in Discord and it can be added to the build.

1. 1

   Install the package

   Use apt rather than dpkg so any missing dependencies get pulled in automatically.

   sudo apt install ./valo_1.2.53_amd64.deb

2. 2

   Launch Valo from your applications menu

   Or run valo in a terminal.

Don’t trust — check

Verify the file yourself

A checksum is a fingerprint of the file. If the fingerprint you calculate matches the one published here, the file you downloaded is byte-for-byte the file that came out of the build — nothing was swapped or tampered with in between.

SHA-512 for Valo-Setup-1.2.53.exe:

nY6oiv29hfjnz52TaGWaWJna6ARJBBf7zKdSjUgl26zT82BVDnNz0prv4uMkUTKyut/IawpnXFRsK8yoP0/hfA==

Calculate it on Windows, in PowerShell:

$bytes = [IO.File]::ReadAllBytes("Valo-Setup-1.2.53.exe")
[Convert]::ToBase64String([Security.Cryptography.SHA512]::Create().ComputeHash($bytes))

On a Mac or Linux:

openssl dgst -sha512 -binary "Valo-Setup-1.2.53.exe" | openssl base64 -A

Honest limitation: only the Windows installer publishes a checksum today. The Mac and Linux packages do not yet — that is a gap in the build pipeline, not a judgement about those files. Until it is closed, the strongest check on any platform is to upload the downloaded file to VirusTotal, which scans it with about seventy antivirus engines at once.
