I'm implementing an urgent fix for Karabiner-Elements on macOS 26.1. (The work is mostly complete.)
November 7, 2025 at 2:24 PM
I've released Karabiner-Elements 15.6.0.
Updates include improved macOS 26 support, lower CPU load, and expression support in Complex Modification rules.

My favorite feature is the ability to temporarily disable all device rules in EventViewer.

There are plenty of features I want to implement, but without proper Liquid Glass support the UI breaks, so I've been focusing on full macOS 26 support.
October 8, 2025 at 11:06 PM
It is a small thing, but in the beta I improved the UI overall: removed unnecessary padding, standardized inconsistent spacing, and increased the number of items visible at once.

I released TrueWidget 2.4.0. This release is primarily focused on code maintenance.

I got a bunch of unexpected freebies with my switch spring order from RNDKBD, it almost feels too generous.

I've released Karabiner-Elements v15.5.0 with minor bug fixes and new warnings to help users avoid common issues.
karabiner-elements.pqrs.org/docs/release...

The highlight for me is a new menu bar option that lets you enable beta updates. Honestly, I wish I had added it much sooner!
July 29, 2025 at 2:36 PM
I've confirmed Karabiner-Elements and my other apps work well on macOS 26 Tahoe.
June 29, 2025 at 1:51 PM
I released Karabiner-Elements v15.4.0.
It includes a number of improvements, most notably, I've removed all the old UI code, which has led to more stable and consistent behavior.

My favorite small new feature is the ability to temporarily pause event capturing in EventViewer 🥰

The beta version of Karabiner-Elements brought major improvements, and I've now completed two of the most important goals: migrating to the SwiftUI life cycle and upgrading to Swift 6. With that done, development has reached a key milestone, and I'll start shifting focus to preparing for release.
June 22, 2025 at 2:44 PM
Got a new keyboard, back to mechanical switches.
I was using 20g optical switches before, so 35g feels a bit heavy. Still deciding whether to swap the springs.
June 14, 2025 at 12:10 AM
Since the C++ package manager cget is no longer usable, I'm transitioning to conan.

I've finally been able to make some time, so I released TrueWidget 2.2.0.
Among the new features, my favorite is the Auto Compact mode, which automatically switches to compact mode when there's only one display.

I haven't had much time to work on software lately, but I still managed to update the Thunderbird extension for Thunderbird 136.
Just updating the strict_max_version in manifest.json wasn't enough, I also had to switch from ChromeUtils.import to ChromeUtils.importESModule.

I added Auto-compact-mode in the beta version of TrueWidget.
This mode displays the widget in normal mode only when an external display is connected.
February 20, 2025 at 2:26 PM
The latest beta version of Karabiner-Elements includes several significant updates, including headset support. This allows you to customize volume buttons and other controls.
February 17, 2025 at 11:54 PM
The awake ratio I added to the TrueWidget beta turned out to be surprisingly interesting. I thought I kept my Mac running much longer, but it was only around 60%.
February 9, 2025 at 4:07 AM
I've spent the past few days optimizing my setup for the Xreal One.
The level of freedom it offers, especially in terms of posture, is incredible. I don't think I can go back to a regular monitor now.
February 4, 2025 at 1:55 PM
I added awake time to TrueWidget in addition to uptime. It also displays the awake ratio.
