Unable to open program

christina jonas
Hello, I used the link for Mac OS X download and was able to successfully download onto my laptop.  When I click into the application, a notification appears that the program cannot be opened. Is there a way to resolve this issue and gain access into the program? Thank you!

Did you look at the installation notes (https://imagej.nih.gov/ij/docs/install/osx.html)?

Here a summary:

The first time you run ImageJ, you may get get an "ImageJ can't be opened because it is from an unidentified developer" message, which can be bypassed by right clicking on ImageJ.app and selecting "Open" from the drop down menu

MacOS 10.12 (Sierra) introduced a security feature called Path Randomization that can cause ImageJ to not work as expected. Path randomization is in effect if the "ImageJ home" path shown in the Image>Show Info window starts with "/private" and plugins are not installed in the Plugins menu. You can disable path randomization by dragging ImageJ.app to another folder and then (optionally) dragging it back.

If the "ImageJ" window is too small, set "GUI scale" in the Edit>Options>Appearance dialog to a value greater then 1.0.
