Zerene Stacker Beta Testing Downloads

Looking for an explanation of how our “beta channel” works? See HERE for an explanation.

Note: Because these beta versions are downloaded relatively few times, they are sometimes not recognized as known good software by anti-malware packages. You may have to override your anti-malware's behavior of refusing to run unrecognized software.

If you have other security concerns about the beta installers, please see How To Validate A Download.

Current beta is:

  • Mac OS X (newest): ZS-MacOSX-SA-T2020-03-22-2054-beta.zip, downloads as a .zip file that automatically expands into an application bundle named ZereneStacker (.app).
    This is the recommended bundle for modern Macs running macOS 10.14 or above. It is self-contained and includes its own Java 12 runtime environment.
    Length 52,887,773 bytes
    MD5 checksum d255ed813212a52799bb9ad744ecf023
    SHA-1 checksum d86ec1277266e12e041e4a499bfbaf5a47141e9e
  • Mac OS X (interim): ZS-MacOSXinterim-SA-T2020-03-22-2054-beta.zip, downloads as a .zip file that automatically expands into an application bundle named ZereneStacker (.app).
    This bundle is suitable for Macs running macOS 10.9 through 10.14. It is self-contained and includes its own Java 12 runtime environment.
    Length 52,332,831 bytes
    MD5 checksum d709f0a6c2f85066fce149416fac3942

  • Mac OS X (old): ZS-MacOSXold-SA-T2020-03-22-2054-beta.zip, downloads as an application bundle named ZereneStacker (.app).
    This bundle is not self-contained. It requires a Java runtime environment installed by Apple, and will prompt for installation of Java if one is not already installed. It runs as 64-bit where the processor and operating system support it, and as 32-bit otherwise.
    Length 8,605,299 bytes
    MD5 checksum 3e8b09f7e1131146744b7e87be7e8fdf
    SHA-1 checksum d8cc2f4083654591e33b9f034386b5637efa17ba

Note: On Macintosh and Linux, if you already have Zerene Stacker installed and are downloading a new version to update it, then you need to manually move the old version to trash, and move or rename the new version to replace it. Otherwise both versions will continue to be available, and you will run whichever one you happen to click on. For further information, see the FAQS on “Installing and Updating”. On Mac, when trashing out the old version, do NOT allow any third party uninstaller or cleanup applications like “AppCleaner” to run. In their enthusiasm to eliminate files that they think are not used, they're likely to also delete files you really do need, like your license key and Zerene Stacker configuration files.
