Yes. I use ATP on a Mac. I had a lot of trouble with it crashing. I got on chat with the Fidelity helpdesk today, and he said part of the SPP was corrupted. He walked me through a process to delete the app and activity in the library, then reinstall. It works great now.

I feel it’s kind of slow. I’m on 16 GB ram. What do you have? It should run it. Does it just have the Icon on the dashboard and never opens? Try closing everything before opening or uninstalling it. ATP always opens for me but takes some time.

Steve R:

I have a Macbook Pro and a custom built Windows PC. Active Trader barely opens on the Macbook because it takes up so much of its drive. The custom PC works great.

John A:

I’d use another trading platform, but I was hoping to use Active Trader Pro because most of my trading is on Fidelity, but I really want/need to learn hot keys.

Juan G:

It has issues with the latest operating system update, you should call customer support.

John S:

I cannot get mine to install or open, I tried everything multiple times, and it will NOT work! I googled this, and there are many known issues with Active Trader Pro and Mac compatibility.

  1. Spend two hours with Fidelity ATP support without any luck to install the ATP software. After entering system password to allow outside software to install on MacOs, as soon as it begins to install, it crashes the install and says “Installation failed”. MacOs Ventura 13.3.1. Uninstalled security software, and also granted permission to install applications from outside Appstore in a security setting. Nothing works.

  2. The problem with the installer is it fails to download DotNet 4.6.2. You can see this in the install log file on macOS here: ~/Library/Application\ Support/Active\ Trader\ Pro/Bottles/ActiveTraderPro64/drive_c/atp_install_progress.txt

    An error occured downloading Microsoft .NET 4.6.2!

    The correct download link is

    They need to modify their installer to pull the correct link. Also they need to spellcheck occurred in their error log. It has two r’s ¯\_(ツ)_/¯
