Installing L'Math on MacOS

L'Math can be installed on Windows, macOS and Linux systems. This guide will help you on installing L'Math on macOS.


System requirements

  • macOS 11 Big Sur or newer (Intel or Apple Silicon)
  • At least 2 gigabytes of free space
  • Administrator privileges

This tutorial only works for the free private version

This guide page instructs you to install the free private version of L'Math. You shouldn't follow this guide page if you are installing the organizational version.

Guide for Apple Silicon based Macs

1. Allow installing apps from outside the App Store

Find "Privacy and Security" in the settings. Scroll down and ensure that under "Security" you have chosen to allow applications from "App Store & Known Developers".

2. Download the installation package

Go to the downloads page and pick the right package. If your Mac is newer, it probably has an Apple Silicon processor (like M1 or M3). Then, download the Apple Silicon version.

3. Open the dmg file and move L'Math to Applications

Click the downloaded file to open it. Drag and drop the L'Math app icon to the Applications folder by holding your mouse button down. Wait until the copying finishes.

If you already have L'Math installed, you may update it by choosing to "Replace" the old file, if prompted.

Wait patiently for the app file to be fully copied.

4. Remove the quarantine flag from the app

On new Macs, Apple requires all apps to be signed and notarized (checked) on Apple's paid services. Currently we do not have a paid developer account, causing MacOS to tell you that "L'Math is damaged and cannot be opened". Here is the workaround: remove the quarantine flag from the file.

4.1. Open Terminal

Find "Terminal" in the "Utilities" folder inside Applications. Open it.

4.2. Type in the command!

Copy or type the following command into the terminal: xattr -d com.apple.quarantine /Applications/LMath.app

After this, press Enter. Ta-da: the file is now magically working.

5. Get Mathin'

The app should now work properly.

Step by step

0. Allow apps from outside the App Store

Open the security and privacy tab from macOS settings. Ensure that 'App Store and identified developers' is the selected option under 'Allow apps downloaded from:'. Click on the lock icon if necessary to make changes.

1. Download the installer

Start by downloading the latest program package from the download page. After this, open the installer by clicking on it.

2. Read and accept the license terms

The installer will ask you to read and agree to the license terms (EULA).

3. Drag and drop L'Math into your applications folder

A notice about changing the install location

Please do not pick an installation directory or change the app name to anything with special symbols or letters (or scandinavian åäö) in the path. It could cause issues with some 3rd party libraries.

Copy L'Math into your applications folder by dragging and dropping it over to the folder icon

4. Wait for a moment...

Now you'll have to wait for the application package to be copied over.

5. Open L'Math for the first time

Since L'Math isn't verified by Apple, macOS will not open the application by default.

Open macOS settings and find 'Security and privacy'

Ensure that your system allows opening apps downloaded from other places than the app store. After this, click on the 'Open Anyway' button to open L'Math.

MacOS wants to verify your choice once more. Click on the 'Open' button to verify that you want to open the application.

6. All done!

You are now ready to use L'Math!
