Set the following changes:
1: Frequency - 44100hz and don't bother any higher, you don't need anything more than that
set latency to 256 and test with full note range, if glitchy, try 512 samples and that should do fine,
final setting is this. polyphony limit, set this to 512 notes max,

these are the settings I use on any test mode, I never change polyphony limit below this but if there's a glitch, it's usually to do with the audio interface.

Now, MacOS is a bit of a fickle beast and there's things you can do to handle how MacOS behaves, one tool I swear by is Onyx for mac, you need to use specific versions for each OS as they're tailored.

If you're running Organteq on an older mac, ram upgrade would help you especially if you've upgraded the OS to the max it can support, because each MacOS changes it's needs for systems and sometimes you might find it choking.

thank yourself lucky you're not runnning hauptwerk.

For me, when ever I set up a mac as a clean mac, the first thing I do after running updates and configuring the OS, I install Onyx, then I go through, customise the UI to remove certain processes, etc, then do a full disk clean to remove any rubbish, etc, reboot it, pram flash it, then it's ready to go, that's coming from a former apple engineer.

When I play my organ and use a lot of stops it looks like my laptop isn't capable to process all the notes and stops. I own a Macbook Pro (2010) and a E-Mu Midi 2x2 Midi-interface in which 2 midi-signals come in.
Should I upgrade to a newer laptop or should I use any kind of soundcart?

Yes, Organteq seems to be very resource hungry. I’m on Mac too, 2020  model with i5 processor and 16GB of RAM and Organteq used to be almost unusable when used with some multiple stops. However, it has improved greatly with Organteq 2 so now it’s working quite satisfactory, and as long as I don’t play 10 voices at the same time for an extended amount time in tutti it works just fine.

Another option is to increase the internal latency, even a slight increase of a few milliseconds will take a lot of load off the cpu.  Also, cpu-heavy background tasks can interfere consistently with playback, so those are considerations as well.

Thank you for your reply!
I will try it!

Hello RonaldB3 and welcome to the forum

I have the same problem with a Mac mini late -14, too small ram 8mega. Should get a new mac with new m1 or M2 chip and lots of ram.

I have solved the problem by reducing the number of stops when I record a song, but then before rendering to mp3, I add all the stops I wanted for the powerful sound. Rendering, saving to mp3 works fine, there is no problem for the computer. Have used almost all stops for Bach Toccata and fugue in D minor BWV 565 and G F Handel Hallelujah/Messiah
