Mac OS Tahoe (26)

It looked like the log you posted in post #12 was from a Terminal window. Thanks for clarifying.

I suggest you power the Mac off and on to make sure you are starting from a clean state.

After this, you should be able to launch MinimWatch from the Applications window. If this works and you see the MinimWatch icon in the menu bar, select Show log. You should see lines similar to the following:

MinimWatch 2.2 update 119, Copyright © 2012-2025 Simon Nash. All rights reserved.
Java™ SE Runtime Environment (build 21.0.8+12-LTS-250)
Java HotSpot™ 64-Bit Server VM (build 21.0.8+12-LTS-250, mixed mode, sharing)

This shows that MinimWatch is running on JDK 21.0.8.

The Java control panel is a Java 8 thing and doesn't know about JDK 21. If you are running JDK 21, you should not use the Java control panel.

I tried adding MinimWatch to startup applications. When I click it, I don't get an error message about the file not being found. It launched on startup but showed an error message about local network access being disabled. I was able to fix this by going to Privacy & Security / Local Network and disabling and enabling MinimWatch. This problem does not occur with macOS Sequoia and does not occur if MinimWatch is not added to startup applications.

I have not had any problems with starting MinimWatch from the applications folder. To fix this, I suggest you try dragging MinimWatch to the Trash/Bin and reinstalling it.

All the above testing was done on Tahoe Beta 26.1.

The Mac has a reputation for being simple but the reality is very different for application developers. My experience is that every new version has changes under the covers that break existing applications and need significant effort to diagnose and work around.
