Fidelity Active Trader Pro

The reality is that Fidelity is responsible for their ATP application working correctly on Ventura 13.3.1, just as it did on prior versions. This is why Apple provides vendors with software development kits (SDKs) for each beta point release of macOS, so they can compile, debug, and test their software against any changes Apple may introduce.

If Fidelity failed to do that beta testing with ATP, then there is every chance that Apple updates that would have been caught in the point release betas are now breaking ATP. Don't assume that ATP is automatically using .NET v7 either, or that Fidelity has kept current with any inherent Microsoft changes to .NET. It is questionable if your installing the current .NET v7 release into Ventura 13.3.1 will resolve the problem or further compound it.

Why not talk to Fidelity about their application? They should be able to advise you on whether Active Trader Pro is even workable on Ventura and by what means. Look before you leap… The latest .NET for macOS Ventura is v7 and if the Active Trader Application is expecting an older version of .NET, it may not work on Ventura even if you did install .NET 7.

Did you try to boot into Safe Mode according to How to use safe mode on your Mac and install from there?

Note:  if you have a wireless keyboard with rechargeable batteries connect it with its charging cable before booting into Safe Mode.  This makes it act as a wired keyboard as will assure a successful boot into Safe Mode.

This problem is some incompatibility issue with NET Framework 8.0 and Active Trader Pro; ATP works fine with NET 4.0. I raised a first research inquiry on May 27 2024; however, tech team is OOTO due to the Memorial Day Holiday. New Trouble Ticket will be raised in the morning.

ATP never worked fine on a Mac. It always hung and crashed. It's terrible. It runs a Windows application under the Wine emulation, and it's horrible. Not only that, it hangs under Windows as well running on a Windows Intel-based computer. Join the investment classes that Fidelity teaches online, and you will see how the instructors struggle with this monster of an application. It hangs and crashes for them during classes, and they run it under Windows. It's been like this for years and years.

I moved all my investments to TDAmeritrade back into n 2020 because of how bad ATP was running on the Max. That was before the first M1 Mac was even released. ATP ran horrible on Intel Macs and it runs horrible on Apple Silicon Macs.

ATO even is issues on Windows, as you can witness if you join any Fidelity trading classes, as the instructors constantly struggle with ATP and have run it on two computers concurrently so that if one of them hangs, they can share the other one into the web conference platform.

ATP is hopeless. It’s been years since I reported these issues to their developers, and nothing has improved. If you want to trade with trading software, switch to another brokerage. Schwab bought TDAmeritrade and they are migrating accounts from Ameritrade over to Schwab, but Schwab decided to keep the Ameritrade trading software - Thinkirswim, because it’s superior to the software that Schwab had before the acquisition.

I am running Sonoma on the M1 Macbook. Active Trader Pro will not even load up properly now. It is the only trading software I can not get to work. The problem is now worse after OS updates. I just uninstalled it and gave up.
