macOS (formerly called Mac OS X, then OS X) is Apple's desktop operating system. It is the second most common desktop computing platform after Windows. This page details issues specific to using ImageJ on macOS systems.- 2Troubleshooting

See also the Java 8 page for OS-X-specific issues.

ImageJ becomes very slow after running for a while
There are several reasons ImageJ can run slowly on macOS.
Java painting bug
On OS X, older versions of Java 8 (prior to 1.8.0_45)—as well as all versions of Java 7 (including 1.7.0_80)—are extremely slow at displaying images. You should either upgrade to the latest version of Java 8, or revert to Java 6 (see 'Frequently Asked Questions' below).
Window menu bar bug
There is a bug in Java 8 on MacOS which causes the application to drastically slow down as many windows are opened and closed over time. Make sure you are using the latest version of Java 8, as well as the latest version of ImageJ.
App Nap
On recent versions of OS X—10.9 'Mavericks' and later—there is an 'App Nap' feature which dramatically slows down applications that are not in the foreground. Leave ImageJ in the foreground while it is processing to avoid this issue. (There are also variousways to disable App Nap on your machine, but we have not had much success with them. https://energywashington.weebly.com/hp-officejet-6950-all-in-one-printer-user-manual.html. If you find a solution that works, allowing ImageJ to run fast in the background, please tell us on the forum!)
No title bar in file chooser dialogs
On macOS 10.11 'El Capitan' and later, the operating system no longer includes a title bar for file chooser dialogs. See e.g. this JDK bug discussing the issue.

As a workaround, you can check 'Use JFileChooser to open/save' in the Edit › Options › Input/Output.. dialog.
