M1 tip to improve performance
Something I've been noticing is that if you go into the Simulation Property and change the Number of CPU in Use from the default (12 in my case) to something like 1, performance improves hugely. I've been finding that values between 1 and 5 work well, but this might be specific to my hardware, so try out different values for yourself. I only wish that this parameter was saved with either the document or as an application preference. It seems to change back to the default of 12 every new session.

good to know thanks, this for the V6 or the beta V7?
I ordered an M1 max CPU 10-core, GPU 32-core - RAM 32GB in order to use CLO in Mac enviromet and I'll try the beta. I hope I made the right choice0 -
multimago I've found that changing the number of CPUs can alter performance in both 6 and 7 and also MD… I really don't know what the rule is here, only that I've noticed better performance when using a lower amount of CPUs – might be good to get someone else try that too to verify.
I'm very far from being an expert in Clo and MD, but I did immediately notice an improvement in viewport and UI performance in the open beta 7.0 which is very good to see. At the default UI layout, I currently find MD unusable on all my Mac systems, but the Clo 7.0 open beta seems to be really nice and fluid – how things should be. So personally I don't see any reason why you will be disappointed with the Mac Studio for Clo. I have experienced a few problems with the Mac Studio in general, but hopefully these are things that will get fixed further down the line with OS updates, I don't know … it's still early days for me with the Mac Studio too.

thanks for the comprehensive answer! that's what I wanted to know.
Probably the development on mac is still in progress, I hope that the performance can at least be similar to a mid-range PC with NVIDIA RTX card.

multimago I don't think that Clo utilises any of the Mac's GPU capabilities, ie. you can't do any simulation on the GPU. I've been using Redshift (GPU renderer) on my Studio Ultra and I would say that the GPU performance is very approximately 70-80% of what I was experiencing using a single AMD 6900XT in eGPU enclosure.

I just wanted to add something to this after running a few tests today…
Running an animation sim on my Mac Studio Ultra at different 'Number of CPU in Use' values, I noticed that I got the fastest simulation time at a value of 7. The default when I open Clo is 10 which seems to give abysmal performance.
I also ran the same animation sim through my iMac 10 core i9 and noticed a similar thing, ie. that Clo's default 'Number of CPU in Use' value doesn't give the best simulation performance. I found that lowering from the default of 12 to something like 9 gave better performance. I also noticed that the simulation time was more or less equal to what I was getting on my Mac Studio Ultra, so I'm wondering just how optimised Clo 7.0 Beta actually is for M1 at this point, because I'm not really seeing any simulation speed gains over my Intel Macs.
Another thing worth mentioning with regards to the Clo 7.0 Beta is that when running an animation quality sim, I'm finding that I can't stop the simulation, Clo doesn't respond. The only way I can stop an animation quality simulation is to either force quit the application or make sure to set my frame range to something low if running an animation so that it stops when it reaches the final frame.

sorry my delay, but I took the computer yesterday and did some tests (M1 max CPU 10-core, GPU 32-core - RAM 32GB).
I confirm what you said about the CORE number, this is so strange; Moreover, If the data load grows (more clothes) or with small particle distance the comptuer fizzes (worse than on an intel mac), but this is a beta problem I think.
The performance is better with the BETA 7 and this is awesome!! but we are still far from a PC with an RTX 3000 series (with lower price)
Can we hope for more? I hope so, this is a beta of course. Running Clo in OSX enviroment is what I need.
