Micro-Manager versions

Micro-Manager 2.0 is the actively developed, current, version of Micro-Manager that you should use unless there is functionality in 1.4 that you need. 1.4 is no longer developed (except for the ASI diSPIM plugin). Nightly builds are usually fine to use, and have the latest features and bug fixes. If you encounter a bug in a release version, always test with the latest nightly build to see if the bug has been fixed already.

Micro-Manager 2.0.0 (July 13, 2021)

It is highly, highly recommended to use the latest nightly build instead of the release build. These have 3 more years of development and bug fixes and have proven to be very stable. For historic purposes we leave the release build up here.

Due to security features of macOS 10.12 and later, Micro-Manager may not start when opening ImageJ.app. To circumvent this, within the Micro-Manager folder in Applications, hold command and drag ImageJ onto the desktop. Then hold command and drag it back in. Then try running again. In addition, you need to CTRL-click or right-click and select Open (instead of simply double-clicking) the first time you open it. See Installation Notes.

Partial list of differences with 1.4

  • Completely re-designed API
  • Better looking User Interface with Day/Night skins
  • Pycro-Manager
  • User Profiles (settings can be saved per user)
  • Image Inspector with overlays (time stamps, Size bar)
  • Versatile viewer with build-in Projection
  • ClearVolume 3D viewer integration
  • Export as displayed to ImageJ

Nightly Builds

Nightly builds are almost always stable and a better choice for most users than the latest official release.

Older nightly builds:

Micro-Manager 1.4.23 (June 30, 2021)

Requires Windows 7-10. Windows 10 recommended. Device drivers may have other requirements.

Requires Mac OS X 10.5 or greater. Device drivers may have other requirements.
(if the application does not open when double-clicked for the first time, try ctrl-click or right click, then select “Open”.)

Micro-Manager 1.4.22 (August 14, 2015)

Read the Known Issues.

Requires Windows XP, or 7-10. Windows 7 recommended. Device drivers may have other requirements.

Requires Mac OS X 10.5-10.10. 10.11 (El Capitan) is not yet supported. Device drivers may have other requirements.
(OS X 10.8 and later: if the application does not open when double-clicked for the first time, try ctrl-click or right click, then select “Open”.)

Known issues in 1.4.22

  • If you use AndorSDK3 (Andor sCMOS cameras) and experience a crash upon starting Micro-Manager (or loading a hardware configuration), please upgrade to the 20150820 nightly build (Windows 64-bit, Windows 32-bit)
