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:

  • macOS (Intel cpu): ZS-MacOSX-SA-T2021-05-05-1700-beta.zip, downloads as a .zip file that automatically expands into an application bundle named ZereneStacker (.app).
    This is the recommended bundle for modern Intel Macs running macOS 10.14 or above. It is self-contained and includes its own Java 11 runtime environment.
    Length 45,910,024 bytes
    MD5 checksum 955d15ed811f66261e6824ed4f711c8d
    SHA-1 checksum 68f041432db5be0b0b20f774b7a5ed3cc310d392
  • macOS (M-series ARM cpu): ZS-MacOSX-ARM-SA-T2021-05-05-1700-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 with ARM cpu (“Apple silicon”). It is self-contained and includes its own ARM-native Java 11 runtime environment. Rosetta is required for the launch program and a few helper programs – so macOS will report the package as “Intel” – but all the heavy computation runs ARM-native.
    Length 45,018,154 bytes
    MD5 checksum 352af0f4bd5cafc95de0f352c5731d60
    SHA-1 checksum b6d65b46448ac1a4ce35fbf8eb020c1928ee9881
  • macOS (interim): ZS-MacOSXinterim-SA-T2021-05-05-1700-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 runtime environment.
    Length 52,529,252 bytes
    MD5 checksum 78030e1dd79fa511495f4fd667a5a275
    SHA-1 checksum 7f0b1275044ae85c70aaaca08200e1670ff9d805
  • Mac OS X (old): ZS-MacOSXold-SA-T2021-05-05-1700-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 8,650,073 bytes
    MD5 checksum e69024c312d210fdd77c089c6c50996b
    SHA-1 checksum ab8e9a05c3152f5e4b162bfba1a22e9abe2b207c

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.
