Codex Account Switcher 3.0

Version 3.0 is a ground-up redesign for macOS 27, with a much lighter app underneath.

A new Liquid Glass design

One glass panel. The panel is now a single Liquid Glass sheet with a standard toolbar. On macOS 26 and later it uses Apple’s native glass, so it follows your transparency setting.
Tabs instead of back buttons. Move between Accounts, Resets and Settings with one tab control. The Resets tab shows how many credits you have.
Limits you can read at a glance. The account you’re using shows two rings, one for the 5-hour window and one for the week. Other accounts show slim meters, and the one with the most room left is marked “Best next”.
Calmer menu bar. The menu bar item is now a small usage ring next to the account letter. The text stays plain until you’re nearly out, then turns red. A spinner shows while you switch or use a reset.
Clearer confirmations. With “Confirm before switching” on, the account row asks “Relaunch ChatGPT as B?” with Cancel and Confirm, right where you clicked. Accounts that need signing in again show a Sign In button.
Settings that feel like macOS. Grouped lists with real switches and pop-up menus, a live preview of the menu bar item, Rename and Log Out for each account, and a compact health summary.
A better Resets view. A summary of how many credits you have, when the next one expires and how many are urgent, then every credit by account with colour-coded days left.
Light and dark. Every screen is designed for both.

Switching finishes several seconds sooner. The app now watches for ChatGPT to quit and reopen instead of waiting a fixed time.
The panel opens instantly. It no longer runs a codex-auth check on the main thread every time it draws, and no longer re-downloads every reset credit each time you open it.
The open panel only redraws when something it shows has changed, instead of every few seconds.
Background work is lighter: no hidden menu rebuilt on every refresh, no 20 ms polling while commands run, saved sign-ins indexed once, and timer wake-ups that macOS can group together.
Usage checks use their own cache-free connection, so figures are always current and responses containing sign-in tokens are never written to disk.
About 2,400 lines of old code are gone, including the retired API mode.

Download Codex-Account-Switcher-v3.0.zip below and move the app to Applications.
The app isn’t notarised yet, so the first time, right-click it and choose Open.
If you’re new, install codex-auth and run codex-auth login once for each account.

Upgrading from 1.8? Replace the old app. Your accounts, labels and settings carry over.

Needs macOS 14 or later. Designed for macOS 27.
