Resing MAX will not connect no matter what - AI Engine Unreachable

Hi. I’ve figured out a more reliable method, so I’ll share that with you.

(Preparation)

(1) First, open the most recent log file in the /Users/Library/Application Support/IK Multimedia/ReSing/ReSingEngine/logs folder to see which port your Mac(ReSing) is attempting to use. In my setup, it was port 50000, but I think it’s probably the same for everyone.
By the way, since the Library folder is hidden, if you can’t find it in Finder, you’ll need to press Command+Shift+. (period) to make it visible .

(2) Next, make sure to have the Terminal window open. Launch ReSing, and when you see the “Starting AI Engine” screen, switch to the Terminal window to perform the operation .

(Practical Step s)

(3) Launch ReSing and, while waiting for the AI Engine to start, run the following command in the termin al:

sudo lsof -P -i :50 000

* If the port number is not 50000, please change it to match your environm ent.

This should list the components currently using port 50000.

Pay attention to the component name in the far left column and the PID immediately next to it. (The PID is usually a 2- to 4-digi t number.)

Next, use the following command to stop every component except Resing one by one:

sudo kill -9 PID

(4) If you can close all components other than Resing while Resing is searching for the AI Engine, Resing should launc h shortly.

(5) In my environment, port 50000 is frequently accessed by printer-related software, which causes interference. Therefore, the steps described above are not a one-time fix; if Resing fails to start, you have to repeat the same procedure (using `lsof` and `kill`) each time.

I hope this helps more people get Resing up a nd running.

Thank you so much for taking the time to write such a detailed explanation and workaround!

I have exactly the same issue on one of my MacBook Pros, so your findings are extremely valuable. I haven’t had the chance to test your method yet, but I definitely will as soon as possible.

It’s also very interesting to know that other software, such as printer-related services, can interfere with port 50000. Hopefully IK Multimedia will address this properly in a future update, but in the meantime your workaround could be a real lifesaver.

Thanks again for sharing your research and helping the community!
