Is it safe to delete caches?+
Yes. Caches are temporary data that apps rebuild when they need it. An app may feel a little slower the first time you open it after cleaning.
Can I get my files back?+
Cleaned files go to the Trash by default, so you can put them back from there. If you turn off “Move to Trash instead of deleting”, or choose to empty the Trash, that part is permanent and Tidy warns you first.
Why does macOS say Tidy can’t be opened?+
Tidy isn’t notarized by Apple yet. Right-click the app, choose Open, and confirm. You only need to do this once.
Do I need to give it Full Disk Access?+
No. Most of Tidy works without it. Full Disk Access only lets it scan a few protected places, such as Safari’s cache and the Trash.
What does the Health tab check?+
Heat, the apps using the most CPU, temperatures and fans where available, battery health, disk SMART status and free space, memory pressure and swap, and kernel panics in the last 30 days. Each gets a Good, Check or Problem. It looks for warning signs; it doesn’t diagnose hardware faults. For that, it explains how to run Apple Diagnostics.
Why don’t I see temperatures or fan speed?+
Not every Mac reports them to apps. When yours doesn’t, that card says so and the rest of Health works as usual, including the heat level.
Why isn’t Tidy in the App Store?+
App Store apps run in a sandbox that can’t reach other apps’ caches and leftovers, which is exactly what a cleaner needs to do.
Does Tidy collect any data?+
No. Tidy has no account, no analytics and doesn’t send anything anywhere. It only looks at files on your Mac.
