What Topics Does the Michel Fortin Blog Cover?

Updated

The Michel Fortin blog at michelf.ca is a developer's journal tied to his Mac and iOS apps. Based on the posts listed on the site, it covers four main areas: app release announcements, Mac display and color technology, macOS and hardware transitions, and app bug fixes. It is not a general tech news blog — each post connects back to Fortin's own software, such as Black Light, Gamma Control, or Sim Daltonism.

App Release and Feature Announcements

The most visible category is new-version announcements for his apps. The site lists "Introducing Black Light 3" (December 15, 2023) and "More Hot Keys in Black Light Pro" (February 13). These posts explain what changed in a release and what new capabilities users get.

If you use Black Light or Black Light Pro, this is where you learn about major version changes and feature additions like expanded hot-key support.

Mac Display and Color Technology

A second thread is technical writing about how Macs handle displays and color. Two examples appear on the page:

  • "Brighter than White — EDR on Macs" (December 5, 2020) — covers Extended Dynamic Range on Mac hardware.
  • "Sim Daltonism's purple bug" (June 19) — a defect write-up tied to his color-blindness simulation app.

This category suits readers interested in display calibration, HDR/EDR behavior, and color perception tools — the same territory as his Gamma Control app, described on the site as a way to "calibrate your screen."

macOS and Hardware Transitions

The blog also tracks platform shifts that affect his apps. "macOS Big Sur and M1 Macs" (November 11) is an example: a post about adapting software to a new macOS release and Apple's move to Apple silicon. Expect this kind of post around major OS updates or hardware changes.

Bug Fixes and Developer Notes

Shorter posts document specific defects and their fixes, such as the Sim Daltonism purple bug entry. These are useful if you hit an issue in one of his apps and want to know whether it is known and resolved.

How to Use the Blog

If you want to… Look for posts about…
Track new app versions Black Light 3, Black Light Pro hot keys
Understand Mac display/color behavior EDR on Macs, Gamma Control, Sim Daltonism
Prepare for an OS or hardware upgrade macOS Big Sur and M1 Macs
Check whether a bug is fixed App-specific bug posts

The blog archive is linked from the site's main navigation, alongside Services, Contact, and the app list. Posts are infrequent and event-driven — published when an app ships, a platform changes, or a notable bug is resolved — so checking the archive periodically is more useful than expecting a regular schedule.
