Use your iPad as your Mac mini’s display. Automatically.

SideMini creates the display a headless Mac needs, starts Sidecar at login and reconnects after sleep or a dropped link. Set it up once with a monitor attached; after that, power on and use your iPad.

Why it works

Sidecar needs a screen before it can become one.

A headless Mac has no real framebuffer, so a normal Sidecar connection starts and then disappears. SideMini gives macOS a display first, then hands that display to your iPad.

Set up once

Three steps. The first two happen once.

Keep a monitor attached for the initial setup and test. Once the automatic behavior works, the monitor can go.

01

Install and choose your iPad

The welcome guide checks Sidecar, Wi‑Fi, Bluetooth and your Apple Account, then runs a test connection.

Once
02

Turn on iPad Only

One switch enables start-at-login, automatic connection and reconnect. Startup security remains your decision.

Once
03

Unplug the monitor

Restart, wake or reconnect. SideMini waits for the iPad and restores the display without Control Center.

Automatic

The useful six

Everything needed for the connection to stay boring.

The uncommon controls remain available in Settings. These are the features that matter every day.

Starts at login

Connects as early as macOS allows, without opening Control Center.

Waits for the iPad

If the iPad is asleep, SideMini retries in bursts and connects when it becomes reachable.

Reconnects after drops

The first retry fires in about two seconds, then backs off and keeps watching.

Remembers the display

Resolution, HiDPI, mirror or extend are reapplied to every connection.

Replaces a dummy plug

A local virtual display gives Screen Sharing a sharp desktop with nothing in a port.

No account or tracking

Activation and revocation use one-way license identifiers. No analytics, usage data or crash reports leave the app.

The app itself

A tab per setup, a switch per tab.

Everything lives in the menu bar and one settings window. The switch at the top of each tab configures the whole setup; the details underneath are there when you want them and ignorable when you do not.

Before you download

What you need, and the honest trade-off.

The trial is the right place to test the complete boot with your own Mac and iPad.

What you need

  • macOS 14 Sonoma or later and a Sidecar-compatible iPad.
  • The same Apple Account with two-factor authentication.
  • Wi‑Fi and Bluetooth on; USB is optional and recommended.
  • A monitor for the first pairing and restart test.

The startup trade-off

A fully unattended cold boot requires FileVault off and automatic login on, because no app can run before macOS reaches the desktop. Prefer encryption? Keep FileVault and use the documented planned-restart or blind-login options.

Good to know

SideMini is signed and notarized, but it cannot be distributed through the Mac App Store. It uses private Sidecar interfaces that Apple may change in a major macOS update.

Five useful answers

Before you rely on it.

More specific fixes live in Help.

Does it work with no monitor attached?

Yes. That is the primary setup. SideMini creates a virtual display before connecting the iPad, then removes it when a real monitor returns.

What if the iPad is asleep at boot?

SideMini retries in short bursts and then watches quietly. Wake the iPad and the connection resumes within seconds.

Do I have to turn off FileVault?

Only for a completely unattended cold boot. Planned restarts and manual blind login let you keep FileVault on.

Does the app send any data?

There is no account, analytics, crash reporting or usage tracking. Activation registers one-way license and device identifiers; a one-way license identifier is checked periodically for revocation. The app keeps working when offline. See the privacy policy.

Could a macOS update break Sidecar automation?

Yes. SideMini uses private Sidecar interfaces that Apple can change. The app reports the problem instead of failing silently, and fixes ship as free 1.x updates.
