If Multilogin will not install on macOS, first check your macOS version and download the installer that matches your Mac processor.

To fix macOS security warning, use “System Settings” → “Privacy & Security” → “Open Anyway”.

If the installer itself shows “The installation failed”, do not disable macOS security immediately. Check the installer package and system requirements first, then use the advanced troubleshooting steps below.

Getting started

• OS version: make sure your OS is Sonoma (14) or newer – if your OS is Ventura (12) or older, consider upgrading, as at this moment it is not supported
• Chip or processor type: when downloading the app, select “M-series” for M1, M2, M3 chips, and “Intel” for other models

Installation issues

macOS error: “Apple could not verify Multilogin is free of malware”

When trying to install Multilogin on macOS, you might see this message: “Apple could not verify Multilogin is free of malware”.

Don’t worry! This happens when you install software not available in the App Store – it’s macOS being cautious.

1. Click “Done”
2. Go to “System Settings” → “Privacy & Security”
3. Scroll down to the “Security” section

Step 2: unblock Multilogin

1. Click “Open anyway” next to “Multilogin was blocked to protect your Mac”

macOS error: “The installation failed”

When trying to install Multilogin app on macOS, you might see this message: “The installation failed”. 

Your Mac’s security settings might be blocking the app installation. But don’t stress – it’s just Gatekeeper being extra cautious. Let’s work around it!

Step 1: disable Gatekeeper temporarily

Gatekeeper is a macOS security feature, but we’ll turn it off just for the installation.

1. Open “Terminal” (search for it in “Spotlight” or find it in “Applications” → “Utilities”)
2. Type this command and hit “Enter”: sudo spctl --master-disable

Step 2: install the app

In Terminal, run this command (replace mlx-arm64.pkg with the actual file name): 

sudo installer -pkg mlx-arm64.pkg -target /

Step 3: re-enable Gatekeeper (optional)

In Terminal, type this command and hit “Enter”: sudo spctl --master-enable
