Sign in

Open the OneLake menu bar icon and choose Add Account…. Your browser opens at Microsoft sign-in. After you authenticate, pick a short alias for the account (for example work, client-a).

That alias becomes the Finder entry OneLake — <alias> (on disk: ~/Library/CloudStorage/OneLake-<alias>/). Pick something memorable.

Add another account

Choose Add Account… again from the menu. You can add accounts from different tenants. Each gets its own alias and its own folder in Finder.

Listing and switching

Every signed-in account appears in the menu bar with its own submenu. The default account is marked with a check; switch the default from an account's submenu with Set as Default. There is no "active" account to switch between — each one is mounted in Finder side by side.

Signing out

Open the account's submenu in the menu bar and choose Sign Out…. Your data in OneLake is untouched.

If sign-in expires

After a long idle period your tenant may require re-authentication. The menu bar header shows a warning when that happens. Sign the account out and add it again to refresh the token.
