For many years, I used iTerm2 as my main terminal emulator and probably spent hundreds of hours in it. Overall, I was satisfied with it, despite some strange recent updates like adding AI features, KeyChain integration, and security vulnerabilities.

macmon
🦀⚙️ Sudoless performance monitoring for Apple Silicon processors. CPU / GPU / RAM usage, power consumption & temperature 🌡️
In recent years, new terminal emulators have appeared. I tried using them mainly for testing macmon. A couple of years ago, I tried switching to kitty, which was faster due to GPU acceleration. However, it required too much customization and still looked very non-native for macOS. GPU acceleration was added to iTerm as well, so I stayed with it.

I also tried Alacritty, but it is very basic and lacks the features I need. Recently, I tested Ghostty, which has gained huge attention – it has nice defaults, but its RAM usage is concerning (around 250MB per empty tab). Currently, it also lacks buffer search, which makes the terminal useless for me.

ghostty
👻 Ghostty is a fast, feature-rich, and cross-platform terminal emulator that uses platform-native UI and GPU acceleration.

wezterm
A GPU-accelerated cross-platform terminal emulator and multiplexer written by @wez and implemented in Rust

WezTerm does not have a graphical interface for configuration, and the setup is done through a Lua file (this is unusual for me, but Vim users are familiar with it). The configuration file can be located at ~/.wezterm.lua or ~/.config/wezterm/wezterm.lua. I prefer the second path because it is where Fish and starship store configs too.

Nutrient
Nutrient – The #1 PDF SDK Library, trusted by 10K+ developers. Other PDF SDKs promise a lot - then break. Laggy scrolling, poor mobile UX, tons of bugs, and lack of support cost you endless frustrations. Nutrient’s SDK handles billion-page workloads - so you don’t have to debug PDFs. Used by ~1 billion end users in more than 150 different countries.

Next, I want to change the theme and set it to follow the current system theme automatically. For the past year, I have been using Catppuccin themes, and I am very happy with them. They rarely have issues where some text colors blend with the background. To make the theme switch automatically based on the current system theme, we need to write a small Lua function (I copied it from the documentation):
