A Fresh Start I had been happily using Oh My Zsh with iTerm2 for years, specifically with the Powerlevel10k theme. It looked gorgeous with its segmented, color-coded design—everything I could want from a prompt. But when my old Mac died unexpectedly, I saw it as an opportunity: instead of simply cloning my dotfiles to a new machine, why not take a fresh look at what's available in 2026? I discovered that the terminal ecosystem had evolved significantly.
