# Install OpenTabletDriver on MacOS

## Introduction

This document will walk you through the installation of OpenTabletDriver (OTD) on MacOS.

If you want the windows instructions, go here: [Install OpenTabletDriver on Windows](/drawtab/guides/drivers/opentabletdriver/otd-windows-install.md).

The official OTD installation guide for MacOS is here: <https://opentabletdriver.net/Wiki/Install/MacOS> This document is s more detailed walkthrough for those who are not familiar with OTD.

<mark style="color:red;">**This document is IN PROGRESS and going through some significant edits. You might encounter incomplete sections.**</mark>

### MacOS

These instructions are shown for MacOS Tahoe. They should be similar to the steps needed on earlier versions of MacOS such as Sequoia but I have not confirmed this.

### CPU architecture

OTD runs on both Intel x86 and Apple Silicon macs.

### OTD versions

* This document shows the steps for OTD version 0.66
* I recommend you use at least version OTD version 0.6.5 or higher. Before version 0.6.5 - OTD does not support pressure and tilt on MacOS

## STEP 1: make sure your tablet is supported.

Check if your tablet is on this list: <https://opentabletdriver.net/Tablets>

## STEP 2: Uninstall any currently installed tablet drivers

* If you have a Wacom, Huion, XP-Pen, etc driver. Uninstall it now.
* Once you are finished uninstalling, I recommend restarting your MacOS computer.

## STEP 3: Download OTD

* Click in this link to download [latest release](https://github.com/OpenTabletDriver/OpenTabletDriver/releases/latest/download/OpenTabletDriver-0.6.6.2_osx-x64.tar.gz)
* This downloads a file called `OpenTabletDriver-0.6.6.2_osx-x64.tar.gz` to your Downloads folder.
* Double-click on the tar.gz file that was downloaded.
* You'll see a brief progress bar indicating it is being extracted into a folder
* When the extraction is done in your Downloads folder you will see

* Extract it and drag `OpenTabletDriver` into your **Applications** folder

## STEP 4 Installing

* Run the OpenTabletDriver app.

* If you see this - this is normal. MacOS is trying to protect you. Click **Done**, do NOT click **Move to Trash**
* To fix the "Apple could not verify is free of malware" warning on macOS, go to **System Settings > Privacy & Security**, scroll down, and click **"Open Anyway"** under the security section.

## STEP 5 Launching OTD

Launch OTD from Applications

If no tablet is connected, you'll see this

<div align="left"><figure><img src="/files/n0zKLwlJ9ED7dVdkFLre" alt="" width="563"><figcaption></figcaption></figure></div>

Once a tablet is plugged in the UI will change

<div align="left"><figure><img src="/files/Yaa4MDOAtkKySrIMICRh" alt="" width="375"><figcaption></figcaption></figure></div>

At the bottom left you'll see

the Outout mode set to Absolute Mode

The Tablet identified (the screenshot shows Wacom PTH-660 which is the Wacom Intuos Pro 2017 Medium)

The very vetical looking shape on top is a the "virtual desktop" that contains two monitors stacked on top of each other.

Right click on one of the monitors and select which one the tablet should be mapped to.

Now it will look like this

Now right click on the bottom are and select **Lock Aspect Ratio**

Once you do you'll see a slight change in the bottom area

This setting is important because it will stop distortion of strokes

## STEP 6 Configure the Pen

Under Pen Settings, you'll see this as ghe default settings.

Leave it alone for now.
