Jiggler "Zen mode" not functioning on MacOS 26.0 (Tahoe)

[steventrotter]

The app is not preventing my Mac from sleeping while running 26.0 Beta (25A5316i).

Usually this turns out to be an error in preferences settings, or Jiggler is not active (no checkmark next to "Jiggler Enabled" in its menu, and a dimmed icon in the menu bar, meaning that it is not enabled). But maybe Apple has actually broken Jiggler; always possible. I don't have any cycles to look into it for a while, and I'm not on this macOS version anyway so I can't look into it anyway, sorry.

Hi @sonoptik. Did you check the above things? Preferences settings, and that there is a checkmark next to "Jiggler Enabled" in its menu? I'd like to know with some certainty whether it is really broken on Tahoe or not. Thanks.

Also, to folks encountering this issue: note that since Jiggler is open-source on GitHub, if you're a developer you could fix the problem and submit a pull request. That would be quite helpful, as I don't have the cycles to devote to Jiggler these days. I'd be happy to add your name to the credits if you do the work to keep it limping along. :-O

It looks like Zen mode no longer works with macOS Tahoe. Standard mode continues to work as usual.

Hello, I’ve noticed that the Jiggler (1.9) app is no longer functioning properly. No matter how I adjust the settings, Zen mode doesn’t work as it used to. It stopped working after I updated my software to MacOS Tahoe (version 26). I am not using a beta OS. I've tried disabling and enabling Jiggler on the Jiggler menu, turning Jiggler on and off in system preferences/privacy and security/Jiggler to permit the app to use my machine, deleting the app and adding back. Nothing works to enable Zen mode. Standard Jiggle appears to work fine but Zen mode is what I use and so do many others. Id be so grateful to get this fixed.

I tested this on 26.0.1 and it is working. The only thing which is not working is Zenclick - resetting system idle time. Other options like click or wiggle are still functional.
Please update for the zen click too, it's by far the best option. Don't hesitate to contact me if you have questions from my testing.
Many thanks.

I updated the title to reflect what appears to be the situation. "Zen mode" jiggle depends upon APIs provided by macOS that tell the system to stay awake. Apple appears to have broken those calls, and I don't have the cycles to figure out why, or how to fix it (and I'm not on Tahoe anyway, and won't be for some time). It would be great to get a pull request from somebody to fix this problem.

Just opened a PR #36 and as luck would have it, I didn't check that PR #35 was already opened... Sorry @MarinSavca

I did do a few different fixes:

• Overlay appeared off to the right in Sequoia and Tahoe
• Accessibility constantly being requested in Tahoe even when already allowed in System Preferences during Debug and such
• Took a little bit of a different approach to fix Zen jiggle in Tahoe
• Added logic to #define NSLog differently in production builds so no one has to comment/uncomment them

Thanks @kumichou! This sounds great. I'll get to these PRs as soon as I can; I apologize for the delay, I'm really swamped and stressed right now. :-<

@bhaller Tahoe was still blanking the screen eventually so I incorporated the fix from @MarinSavca which fixes the eventual sleep issue I was encountering after my original fix

Hello, any updates on getting Zen jiggle working with MacOS Tahoe 26? Looks like the last post was from October 22. I'd greatly appreciate it. @bhaller

This issue was fixed by @MarinSavca and @kumichou; thanks very much to both of them for their work! The Jiggler 1.10 release is now available on the Releases tab (https://github.com/bhaller/Jiggler/releases/tag/v1.10), and you can download it directly from there. It'll be up on the Stick Software website soon. Sorry that it took so long to get a fix out; I'm not on Tahoe myself yet so I couldn't reproduce it or test it, and life is quite busy lately. Please comment and reopen if it appears that the new version doesn't fix the problem. Thanks for the helpful comments above.
