Free macOS utility
24-hour screenshot filenames.
Your Mac clock stays how you like it. Mac Screenshot installs a small local helper that keeps screenshot filenames sortable without forcing your whole system into 24-hour time.

What it solves
Screenshots that sort cleanly.
macOS screenshots can be annoying when folder sorting, project capture, and local time preferences fight each other. This helper keeps screenshot filenames practical for real review folders.
Install command
Copy, paste, run, choose your setup.
There is no Apple-signed app for now. The supported path is a Terminal install command that downloads the script to a temporary location and runs it with the Python already included on macOS.
curl -fsSL https://tools.kelownafilmstudios.com/macosscreenshot/macosscreenshot.py -o /tmp/macosscreenshot.py && /usr/bin/python3 /tmp/macosscreenshot.pyWhat it changes
Screenshot name and folder.
If you choose them, the tool updates the macOS screenshot base name and screenshot folder through the normal screencapture settings.
A local helper copy.
The script is copied into your Application Support folder so the watcher can run locally without downloading itself again.
A LaunchAgent watcher.
The main mode installs a small LaunchAgent that watches new screenshots and renames them into a 24-hour sortable format.
Support limits
Small tool, honest boundaries.
Mac Screenshot is built for recent macOS versions. Re-run the same script later if you want to change the screenshot name, folder, or naming mode. By default, it does not change the system-wide Mac clock preference.

If this saves you time, support it on Ko-fi.
The tool is free. The Ko-fi support link still needs the real account URL before launch, so this page does not point people to a placeholder payment link.
