System Compatibility and Requirements for Snooz

Snooz has been developed and validated exclusively on Windows 11.

Snooz supports both Intel-based Macs (including those with the T2 security chip) and Apple Silicon Macs (M1 and newer). Supported macOS versions: 14.3 (Sonoma) through 15.2 (Sequoia).

  2. Double click on the zip file downloaded.

  3. Double click on the SnoozSetup.exe included in the zip file.

  4. Follow the instructions (make sure the previous version of Snooz is closed).

Alternative text

If you encounter issues, see the requirements in System Compatibility and Requirements for Snooz.

On macOS platforms

  1. Download the Installer using the link provided in the Snooz email after submitting your profile.

  2. Double-click on the downloaded file to install.

  3. Drag and drop the Snooz application in the Applications folder.

  4. Since Snooz is not signed yet, you need to mark it as an exception (see the note lower).

Note

To mark Snooz as an exception:
Open a terminal and type either :
find /Applications/Snooz.app -exec xattr -c {} \; or
xattr -cr /Applications/Snooz.app, depending on your environment.

Warning

Ensure that Snooz has full disk access to launch it from the Launchpad by following these steps:

  1. Open System Settings.

  2. Navigate to Privacy & Security.

  3. Click on Full Disk Access.

  4. If Snooz is not listed, click the + (plus) icon, then select Snooz from the Applications folder.

  5. Click Quit & Reopen when prompted.

  6. Relaunch Snooz.

If Snooz does not have full disk access, it may hang when loading a file chosen via the Snooz interface. Launching Snooz from the terminal provides broader disk access than the Launchpad, so using the terminal is recommended if you prefer not to change the settings.

If you encounter issues, see the requirements in System Compatibility and Requirements for Snooz.

On Linux platforms

  1. Download the Installer using the link provided in the Snooz email after submitting your profile.

    • Two files are available: a .deb file and a .zip file.

  2. Recommended - Install Snooz via the .deb file.

    • Open the installer via the Ubuntu Software Center (or Software Install) and click Install.

      • using dpkg (simple direct installation): sudo dpkg -i Snooz-Linux-xxx.deb

  3. Alternative - Install Snooz via the .zip file.

    • Open a terminal in your Downloads folder and run:
