Archil for macOS is a menu bar app that mounts your Archil disks as native macOS volumes. Browse, edit, and copy files in Finder — your disks behave like local folders, backed by S3 durability.
Archil for macOS uses Apple’s native FSKit framework. There are no third-party kernel extensions or FUSE drivers to install.

​
Requirements

Archil for macOS requires macOS 26 (Tahoe) or later.

​
Install

Install Archil with a single command. The installer detects macOS automatically and downloads the latest signed, notarized release of Archil.app: 
curl -s https://archil.com/install | sh
The script copies Archil.app to /Applications, registers the FSKit extension, and offers to launch the app for you.
Re-run the install script at any time to upgrade. Archil.app also checks for updates in the background and prompts you when a new version is available.

​
First launch

1

Sign in

Click the Archil icon in your menu bar and choose Sign in to Archil. Enter the email address associated with your Archil account, then enter the verification code we send you. Your session persists across restarts.
2

Pick a disk

Once you’re signed in, the menu bar lists every disk you have access to — both your personal disks and any disks shared with you through an organization. Disks are grouped by region.If you don’t have a disk yet, create one in the Archil console and click Refresh Disks in the menu.
3

Mount it

Click any disk and choose Mount. Archil mounts the disk as a native macOS volume, opens it in Finder, and adds a shortcut to your Finder sidebar. From there, you can browse, edit, and copy files just like any other folder.
4

Unmount when you're done

To unmount cleanly, click the disk in the menu bar and choose Unmount. Archil waits for any pending writes to flush to your data source before disconnecting. Quitting the app unmounts every active volume automatically.

​
Latency indicators

Each mounted disk shows its current ping time in the menu, color-coded so you can tell at a glance how responsive the volume is: green for low latency, yellow as latency climbs, and red for high latency. Higher latency means slower reads and writes, so for the best performance mount disks from a Mac that’s geographically close to the disk’s region.

​
Sharing data with Linux servers

Disks mounted on your Mac are the same disks you can mount from Linux servers using the Archil CLI. Files you create or edit on macOS are immediately visible to any other client mounting the same disk, with full POSIX semantics. See shared disks for details on concurrent access from multiple clients.
