Updating TrueWidget’s app icon.
November 16, 2025 at 2:33 PM
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
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.

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 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.

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!

The ComboStick is designed to support attachable keyboard holders, so whenever I switch keyboards, I also create a new holder to keep the keyboard fixed in exactly the same position.

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.

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.

The latest beta version of Karabiner-Elements includes several significant updates, including headset support. This allows you to customize volume buttons and other controls.

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%.

A throwback to the monitor days. The ComboStick wasn't in its optimized shape yet, brings back memories.
February 4, 2025 at 11:13 PM
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.

I added awake time to TrueWidget in addition to uptime. It also displays the awake ratio.
January 31, 2025 at 2:07 PM
I bought the Xreal One, so I'm going to experiment to see how well I can integrate it into my daily use.
At the very least, its standalone 3DoF is fantastic.

The beta version of TrueWidget now supports displaying uptime.
At first, I assumed that ProcessInfo.processInfo.systemUptime would be an easy way to retrieve uptime, but since it doesn't account for time spent in sleep, I had to fetch the boot time using sysctl and calculate it manually.

I updated the page with information about key codes to make it more understandable.
The core process can only process HID Usages, so the key codes in the configuration are also based on it. However, these don't always correspond to the actual key letters.

I’ve released ShowyEdge 6.0.0 after over a year. The main update is the migration to the SwiftUI Life Cycle.
Additionally, the color settings have been improved for better visibility.

When I tried similar in the past, my hands often collided with the cover. Now, the devices are optimized, so I can keep my hands in the home position, so operate without any collisions 😄
(Switching the pointing device to ComboStick made a big improvement.)

My cats jumped onto the keyboard several times while I was working in the terminal, so I created a cat-proof barrier using an acrylic board to prevent any serious mishaps.

With test environments spanning various macOS versions on both Apple silicon and Intel, TrueWidget is an essential tool for visualizing environmental information.
In these environments, Apple Account also differs as well, so I added a display feature in TrueWidget v2.1.0.
January 18, 2025 at 1:01 AM
I adjusted the room layout so my cat can sit next to me. Otherwise, they always end up on my keyboard.
January 14, 2025 at 10:17 AM
I've added the ability to display the application version in the beta version of TrueWidget. This makes it easier to verify whether the expected version of the app is installed, especially in test environments.
January 8, 2025 at 1:14 PM
Previously, I attached fixtures directly to the desk to keep the ComboStick and keyboard in place. However, this setup was not portable.
To solve this issue, I designed a keyboard holder that connects to the ComboStick, allowing me to stabilize its position. It's been working perfectly.

As I've mentioned repeatedly, one of the things I truly appreciate about macOS is how it requests approval or provides notifications for actions that apps could potentially misuse. I especially commend macOS for notifying users about screen capturing, even when it involves Apple's own apps.
