Designed for everyday use
From choosing to restoring, everything stays in one window.
Paletide turns a technical theming workflow into a visual one while preserving the official sidebar, composer, and task interactions.
Your own images
Import PNG, JPEG, HEIC, TIFF, or WebP files and build a personal theme entirely on your Mac without uploading the artwork.
Live crop previews
Preview home and task views separately, then adjust focus and zoom non-destructively before applying the theme.
Native macOS interface
Choose, import, apply, diagnose, pause, and restore themes from one native app window. No Terminal workflow is required.
Official apps stay intact
Themes are applied through a loopback-only local connection. Paletide does not modify the official .app, app.asar, or code signature.
Restore at any time
Pause the theme or return to the official appearance whenever you want, with a clear and reversible path.
Original bundled themes
Six atmospheres, each designed beyond a single background.
Every theme includes separate artwork for the home hero, home background, and task page, with a palette designed to keep interface content readable.
Cloud Nest Otter
A quiet riverside companion for a softer working pace.
Orbital Harbor
Send ideas outward from a still station at the edge of space.
Ring-Tide Vista
Stay focused beneath a planetary ring in deep space.
Misty Pine Valley
Morning light and quiet forest air for an unhurried workspace.
Deep-Sea Fireflies
Small lights drift through the deep and keep ideas visible.
Paper Atelier
Fold color into paper-like forms for a crisp, playful desk.
Custom themes
Use your own images to make the workspace genuinely yours.
Start with one image in all three positions or choose each one separately. Paletide analyzes brightness and focus locally so you can preview the result before applying it.
- Set the home hero, home background, and task background independently
- Adjust focus and zoom with non-destructive crop controls
- Use common image formats while keeping artwork and themes on your Mac

Read articleFrequently asked questions
What to know before you buy.
These answers describe the current macOS product. Compatibility is reviewed as the official desktop apps change.
Which systems does Paletide support?
The current commercial release supports macOS 13 or later on both Apple Silicon and Intel Macs. A Windows version is in development and is not currently sold.
Is Paletide an official OpenAI product?
No. Paletide is an independently developed third-party theme app. It is not affiliated with, sponsored by, or endorsed by OpenAI. Codex, ChatGPT, and related trademarks belong to their respective owners.
Does Paletide modify Codex or ChatGPT?
No. Paletide does not modify the official .app, app.asar, or code signature, and it does not read or rewrite API keys, Base URLs, or auth.json. Themes use a local connection bound only to 127.0.0.1.
Are custom images uploaded?
No. Imported images, crop settings, and custom themes stay on the current Mac. Theme artwork is not sent as part of license validation. Only use images you have the right to use.
Why can macOS say the developer cannot be verified?
The current package has not yet completed Apple Developer ID signing and notarization, so Gatekeeper may block the first launch. Download only from the GitHub Release linked by this site, then use Open Anyway in System Settings > Privacy & Security.
How does a purchased license work?
After purchasing through Xianyu, the seller provides a license code. Open License Management in Paletide, paste the code, and connect to the internet for first activation. The device count and license term follow the product listing.
