Support

Arc is a radial menu for macOS. Hold or double press a key and a wheel appears with the commands for whichever app you are in. If something is not behaving, start here. Most questions have a one line answer below.

Arc stopped responding to the trigger key

This is the most common report, and it is almost always the same cause. macOS revokes Accessibility permission whenever the app binary changes, which includes every update from the App Store. Arc is still running, it just can no longer see the trigger key.

Toggling the switch off and on again does not always clear it. Remove the entry and add it back:

• Open System Settings, then Privacy & Security, then Accessibility.
• Select Arc in the list and click the minus button to remove it entirely.
• Quit Arc and launch it again. It will ask for the permission, so grant it.

If the wheel still will not open, check that Arc is actually running. It lives in the menu bar rather than the Dock, so it is easy to miss when it has quit.

The wheel opens when I did not ask for it

Open Triggers in Arc's settings and raise the activation delay. That is the time you have to hold the key before the wheel appears, and a slightly longer delay stops it firing while you are typing.

If a modifier you use constantly is the problem, switch to double pressing it instead of holding it, pick a different key, or move to a hot corner or your own global shortcut. All of those are in the same pane.

My app is not in the list

About twenty five apps are configured out of the box. For anything else, check Gallery first, which has more profiles you can install in one click.

If it is not there either, open My Menus and build one. Add an app, then fill the eight slices with menu commands, keyboard shortcuts or anything else. It takes a couple of minutes and the wheel will switch to it automatically whenever that app is in front.

One slice does nothing in a particular app

Arc runs real menu items rather than faking keystrokes, which is why it works where an app has no shortcut for something. The trade off is that if the app renames or moves a menu item, the slice pointing at the old path stops matching.

Open My Menus, select that slice, and point it at the current menu path. If you find one of the built in profiles has gone stale after an app update, email us and we will fix it for everyone in the next release.

Trial, purchase and restoring

Arc is free for the first seven days with every feature unlocked and no card required. After that you can unlock it permanently with a single purchase, or take the weekly plan if you are still deciding.

On a new Mac, or after reinstalling, open Upgrade & Purchases and choose restore. Make sure you are signed in to the same Apple Account that made the original purchase. Purchases are handled entirely by Apple, so we cannot see or refund them. For a refund, use reportaproblem.apple.com.

Profiles are not syncing

Profiles sync through your own iCloud account. If a change on one device is not showing up on another, check that both are signed in to the same Apple Account, that iCloud Drive is on, and that Arc is allowed to use iCloud. Sync is not instant, so give it a moment on a slow connection.

Arc Mirror will not pair

Arc Mirror lets a paired iPhone fire a Mac shortcut over your local network, so both devices have to be on the same Wi-Fi network. Corporate and public networks often block devices from seeing each other, which prevents pairing.

Also confirm you granted the local network prompt on both devices. If you dismissed it, you can turn it back on in Privacy & Security, then Local Network, on each device. Then try pairing again from the Arc Mirror pane.

System requirements

Requirement	Detail
macOS	macOS 26 (Tahoe) or later. Arc uses APIs that are not available on earlier versions, so it will not install on them.
Accessibility	Required. Arc uses it to detect your trigger key and to invoke menu commands in the app you are using. It never reads your screen or what you type. See the Privacy Policy.
iCloud (optional)	Only needed if you want profiles to sync between devices.

Reporting a bug

Email shubham_iosdev@outlook.com. The more of this you can include, the faster it gets fixed:

• Your macOS version, and the Arc version from the About Arc pane.
• Which app was in front when it happened.
• What you expected the slice to do, and what it did instead.
• Whether it happens every time or only sometimes.
• A screenshot or short screen recording, if the problem is something you can see.

Feature requests

Send them to the same address. If you want a profile for an app Arc does not cover yet, say which app and which commands you reach for most, and it may well end up built in.
