It’s been a while since the last DejalNews newsletter (over a year!), so I expect I’ll get several unsubscribes from people who forgot they signed up, or are no longer interested, or were added by spammers (I just spent an hour clearing out about a thousand obvious junk emails). I really should publish these a little more often. Lots of updates coming this year, so I probably will.
Time Out 3.0 released
The big news is that Time Out version 3.0 is now available! This major update to my popular break reminder app for Mac includes several huge improvements:
Time Out now requires a minimum of macOS Tahoe (26.0), and has been updated to support Liquid Glass, modern icons, and other recent technologies.
New theme editor, making it easier than ever to add custom themes.
New YouTube, Images, and Text theme types, joining the existing Local HTML and remote Website types.
Exclusions are now Rules, and more powerful, including enhancements to app rules, new fullscreen rule, customizable script-based rules including detecting when in a meeting, and more.
Added a Duplicate Break command.
Enhanced the postpone/skip control limits option to per break, hour, or day.
Improved data format, to support syncing in a future update.
Prior to the Time Out 3.0 release, I had updated several break themes, including updating and adding several YouTube-based themes, and adding a checklist theme. These are bundled with Time Out 3.0, so no need to download them manually if you update to that version… but if you have to remain on version 2.9.7 due to using an older OS version, you can download those themes from the Time Out Extras page.
Simon tip: How can I look for changes in a large binary file on a site?
I previously published a Simon tip, based on a customer query. They wanted to detect when a large binary file like an app changes on a website. While Simon could download the file, I came up with a better solution.
I’m pleased to announce the release of version 3.0 of Time Out, my popular break reminder app for Mac. 🎉
This update includes several huge improvements:
Time Out now requires a minimum of macOS Tahoe (26.0), and has been updated to support Liquid Glass, modern icons, and other recent technologies.
New theme editor, making it easier than ever to add custom themes.
New YouTube, Images, and Text theme types, joining the existing Local HTML and remote Website types.
Exclusions are now Rules, and more powerful, including enhancements to app rules, new fullscreen rule, customizable script-based rules including detecting when in a meeting, and more.
Added a Duplicate Break command.
Enhanced the postpone/skip control limits option to per break, hour, or day.
Improved data format, to support syncing in a future update.
Plus many other changes. Read on for full details.
macOS Tahoe support
Time Out now requires a minimum of macOS Tahoe (26.0).
The buttons at the top of the window now use the modern Liquid Glass style.
Replaced the sidebar and Action icons with modern SF Symbols.
Added icons to menus for macOS 26.
But also respects the defaults write -g NSMenuEnableActionImages -bool NO global setting; if used, icons are hidden from Time Out menus.
Modernized the color pickers.
Updated Break Actions like notifications and the speech synthesizer to the latest technology.
Added a theme editor
Added an Options menu button before Preview on the Break Appearance page.
This menu includes commands to add a new theme, duplicate the selected theme, edit it, reveal it in the Finder, or delete it.
Built-in themes can’t be edited or deleted; duplicate them first to make changes.
The theme editor sheet includes fields for the theme name and comments, author information, credits information, and a pop-up menu to choose the type of theme (see below).
At the bottom is some info text, and buttons to Contribute, Preview, Cancel, or Save the theme.
The Contribute button will attach the theme to an email; you can review the email before sending it to Dejal for consideration to bundle with a future version of the app, and/or list on the Time Out Extras page.
The editor sheet can be resized if desired.
Edit local themes
In the new Theme Editor, choose Local HTML to add or edit a theme that uses HTML within the theme folder. This kind of theme works offline.
It includes a field for the root document name (the main HTML file to display).
It also includes buttons to open the HTML file in an editor of your choosing (which is remembered), or reveal it in the Finder.
Edit website themes
In the new editor, choose Website to add or edit remote themes, that simply show a web page.
It includes a field for the website URL.
Edit YouTube themes
Themes that play YouTube videos can be added or edited via the YouTube Video option in the editor.
It includes fields for the video ID and playlist ID.
To add a YouTube video, simply copy the URL from your browser and paste it into the URL field, and it’ll extract the video ID and playlist ID (if any).
It also includes a field for the video title.
A slider controls the playback volume; drag to zero to mute.
A checkbox lets you start at a random point in the video or a random video in the playlist; if unchecked, there’s a field for the start offset.
Edit image themes
A new kind of theme is Images; you can add any number of images or photos to show during a break.
You can choose to show the images in sequential order or randomly.
Also choose the transition between images.
Specify how many seconds to show each image; set to zero to have only one image per break.
Scale options include Fit to display each full image, with space on sides as necessary, Fill to fill the screen, cutting off edges as needed, or Percent to use a specified percentage of the screen.
Buttons enable adding images from files, or from your photo library (note that the photo library picker may take a long time to load if you have a lot of photos).
The app won’t see any photos other than the ones you choose to add.
Thumbnails of the chosen images are listed; drag to change the order if showing sequentially.
Trash buttons next to each image will remove them from the collection.
Edit text themes
Another new kind of theme is Text; you can add any number of text items to show during a break.
Like for Images, you can choose sequential or random order, and how many seconds to show each one (or enter zero to show one per break).
Choose the text font and color.
Scale the text to use a percentage of the screen (the text will resize to fit).
A vertical offset slider lets you position the text to avoid the control panel.
A button enables adding text.
Enter the text to display; drag the rows to change the order, or remove via the trash button.
New and updated themes
The Sinclair Trails, Dejus Chickens, Dejus Ducks & Fish, and Tropical Rain themes now use the new YouTube theme type.
Added new Coral World and Fireplace YouTube themes.
Added a new Checklist theme, that enables you to add things to remember and check them off.
Added a new Desk Exercises theme, that uses the new Text theme kind, with some simple exercises that you can do while sitting or standing near your desk.
Exclusions are now Rules, and more powerful
The Exclusions page has been renamed Rules, since they are now much more flexible.
The Add (+) button is now in the top-right corner, and shows a menu of the different kinds of rules that can be added.
The Add menu also includes script management items like More…, Reveal Scripts, and Get More, similar to Break Actions.
Each rule now includes a checkbox to enable or disable it, so you can turn one off without removing it.
Application rules now show the path under the app name; if it isn’t all visible, hover over the path to reveal the full location (or make the window wider).
App rules also now support “is” / “isn’t”, to reverse the “open” / “frontmost” option, e.g. to skip a break if some app isn’t being used.
Calendar Events rules now group your calendars by account, if you have multiple accounts. And yes, you can now have more than one calendar rule.
A new built-in rule is Fullscreen Active, to detect when the frontmost app is fullscreen. Useful when watching videos.
Script-based rules are now supported too. Time Out can look in the Rules folder inside its Application Scripts folder, and any scripts there can be added as rules.
Four script-based rules are included initially: FaceTime Meeting, Teams Meeting, and Zoom Meeting to detect when actively in a meeting via FaceTime, Teams, or Zoom, and Valve Game to detect when using a Valve / Steam game, since they don’t always appear as normal apps. More scripts will be added over time, and you are welcome to add and/or contribute your own.
Script rules support “is true” / “is false”, so the script result can be used normally or reversed.
All rules include a menu for what to do when the rule matches, including “automatically skip”, “postpone” by several amounts, and two new actions as follows.
A new action is “ignore natural break”. If selected, when a natural break is detected (the Mac is idle), and this rule matches, the natural break will not be taken. Useful when you’re passively watching a video, to make sure you still get breaks.
Another new action is “treat as natural break”. If selected, when this rule matches, the app will act as though it is idle, even if you’re actively using it. Useful when you’re doing something that is equivalent to a break, like playing a relaxing game instead of working.
The new Fullscreen Active and script-based rules, conditions, and natural break actions are all available as new rewards for recent supporters.
The status messages in the sidebar are now clearer, e.g. showing reasons like “skipped due to Teams Meeting” or “skipped due to fullscreen rule”.
Added a Duplicate Break command
The File menu now includes a Duplicate Break command, along with the existing New Break command.
The Duplicate Break command is only available if a break is selected, and if adding breaks is allowed.
The break Options menu also includes a Duplicate Break command, as pictured above.
The + button in the window will now duplicate a selected break, or add a new one if none selected.
Enhanced the postpone/skip control limits option to per break, hour, or day
Added pop-up menus after the existing options to limit postponing or skipping a break (on the Break Appearance page).
Options now include per break and per hour, in addition to the existing per day.
So for example you can choose to limit yourself to postponing a break only twice before having to take it, to encourage yourself to have more breaks.
Perhaps one of the most popular requests!
Adjusted Reset behavior when From Last Done
The original description for the From: Last Done scheduler option was “Last Done will reset the break after it is completed, so the next break will occur the frequency interval after that. For example, a 10 minute break every 30 minutes will next occur 30 minutes after the break finishes, instead of 30 minutes after it starts (as with the Last Due option).”
But a reset has always set the due date to the break frequency minus the break duration, which didn’t match that description.
So now when From is Last Done, reset will only use the break frequency.
The “work for” label will also be hidden when From is Last Done, since the work interval will match the frequency.
Clarified the supporter trial to reduce confusion
When showing any settings page with supporter rewards being trialed, the info will automatically appear as a reminder.
During a supporter trial, the Support Time Out page has a message clarifying the trial, and lists the supporter rewards being tried.
You might (randomly) be offered a longer supporter trial period and/or a different number of trials, as an experiment.
After the trial ends, the Support Time Out page lists all of the supporter rewards that have been tried.
Now only automatically shows the Support Time Out page once after a trial.
Modernized the in-app purchase view in the direct edition.
But wait, there’s more!
The app data has been modernized in preparation for syncing, coming in a future update.
Fixed a shortcut becoming unavailable when deleting a break that used it.
If the Event Monitor idle detector is not available, now automatically falls back to Event Source.
Improved the reliability of resetting breaks when waking from sleep.
Fixed some issues with the Updates page.
Now shows a red badge next to the Updates item in the sidebar after the app has been updated.
Fixed a rare crasher with the Statistics page.
Numerous other minor improvements.
Want to try it?
Note that Time Out now requires a minimum of macOS Tahoe (26.0). If you are still using an older OS version, you can continue to use version 2.9.7 until you’re ready to upgrade your OS.
If you are using the Mac App Store edition, you can update via the App Store app.
Similarly, if you are using the Setapp edition, it will handle that update for you.
If you are using the direct edition, you can use the Check for Updates feature in the app to update.
Time Out is still free; you can use it for as long as you like without paying anything. But people who contribute to ongoing development by becoming supporters get the advanced features as a reward. You can become a supporter for 3, 6 or 12 months; these one-time payments do not auto-renew, but you can extend your support if you wish. The features will remain available permanently. You can become a supporter in the app, or via the Dejal Store.
I hope you enjoy the many improvements in Time Out!
Time Out 3.0 is now available for download directly from the Dejal website. It will be rolled out to the Mac App Store and Setapp starting on Monday. (I felt it safer to roll out slowly, just in case some issue turns up.)
Version 3.0 includes:
macOS Tahoe support
Exclusions are now Rules, and more powerful
A new theme editor, and image and text theme types
Added a Duplicate Break command
Enhanced the postpone/skip control limits option to per break, hour, or day

If you experience any issues, or have any suggestions for improvements, please contact me.
The data format has changed, but updating will leave the old data intact, so you can freely switch back to the previous release if you wish; any changes you make in version 3 won’t affect version 2.
Want to try it?
Note that it requires macOS Tahoe (26.0 or later). If you are still using an older OS version, you can continue using version 2.9.7 until you’re ready to upgrade.

I’m pleased to announce the first pre-release TestFlight for version 3.0 of Time Out, my popular break reminder app for Mac. 🎉
I have been working on this big update off and on for the past couple of years, and it is finally approaching readiness for general release, though I do plan to add a few more features before that.
This update includes several huge improvements:
macOS Tahoe support
Exclusions are now Rules, and more powerful

Replaced the sidebar and Action icons with modern SF Symbols.
Added icons to menus for macOS 26.
The buttons at the top of the window now use the modern Liquid Glass style.
Modernized the color pickers.
Updated Break Actions like notifications and the speech synthesizer to the latest technology.

If you create new script-based rules that others might find useful, please share them, and I’ll probably bundle them with the app!

A little while ago YouTube changed the requirements for embedding videos in web pages, which broke the YouTube-based themes for Time Out.
I recently came up with a solution for this problem, and have updated the themes on the Time Out Extras page.
I also added a new theme for the Sinclair Trails travels in 2025, plus a couple new scenic ones, of underwater coral and tropical fish, and of a burning fireplace (from the same creator as the Tropical Rain video, which was also updated).
Here are direct download links for the new and updated themes:
I’ll bundle the updates with the next update of the app, but that’ll be a while off, so if you want to use any of these themes, download them from those links.
To install these themes:
Go to the Break Appearance page within Time Out.
Choose Reveal Themes from the Theme menu to open the Themes folder in the Finder.
Decompress the downloaded archive(s), if your browser didn’t do it for you.
Drag the resulting folder(s) into the revealed Themes folder.
That’s it; the new theme(s) will then appear in Time Out’s themes pop-up menu.
Hey! Long time user and supporter of TimeOut. Is there a way we can add a checklist to pop up for the break theme?
I just LOVE checklists, its so satisfying to click off a task such as exercises during breaks. I know there are other solutions, like I could just customize the text and put an X there, but checklist is just so much more satisfying.
I replied that such a theme would be beyond my HTML skills, but I could try asking ChatGPT to write it for me… which I did. After a number of refinements, we came up with something that works quite well:
You can add, edit, remove rows, and toggle the checkmark. They are only saved on your local Mac, and are specific to the break, so two breaks using the Checklist theme will have separate lists.
If you want to use Simon to detect when a large binary file like an app changes, one option would be to use a Web Page test with the download URL. But that would end up storing the entire download in the test, slowing it down and possibly causing loading or saving failures, as that large amount of data is encoded in JSON.
A better option is to just get a checksum of the file. That would only need to store a small amount of data, and would still result in a change when combined with a filter like Any Change.
Here’s a custom script-based service to assist with this; you can download it from the Simon Extras page:
