When I apply pressure to the pedals every avatar looses bodies except for shoes and heads. When I stop pedalling, the bodies come back. This is consistent and repeatable. I’ve completely re-installed Zwift. If I quit event and completely leave Zwift and then re-start Zwift then it behaves normally (bodies are there even if I’m pedalling). But if I close out of Zwift and return the next day the problem happens again. Anyone?
That looks like MacOS, can you provide your system details?
Model type (eg Mac Pro 7,1)
RAM, MacOS version, GPU (If on an Intel Mac)
If you click on the Apple menu and choose About this Mac, click on the MacOS version and you can copy the exact details, eg:
15.0.1 (24A348)
Is your system overheating at all or do you have minimal RAM?
Thank you for your interest!
Mac mini M1 8GB Mac Sequoia 15.0.1
System is not overheating, I do have a large monitor though. It only looses people when I’m applying power. when I let off the power they come back.
Also remember that if I quit zwift and restart zwift (no system restart required) it works perfectly.
This is the normal failure mode when the system runs out of CPU capacity. Exactly why that’s happening in your case I do not know but it’s normal when the system doesn’t have enough juice to handle demand. I’ve not seen that on an M1 Mac.
See if anything else is running in the background and if so, close those applications.
It might help because this machine is obviously a lower spec one.
Ok these are good ideas. Nothing else is running. I used to run Zwift, Discord, OBS, Spotify and Chrome, recording my race with two HD webcams for YouTube on this mac. It might be old but the last few months have had this issue. I think my best next course is “Clean install” of Mac OS without anything else only Zwift. If that does not do it then I’m asking Santa for a gaming PC.

This could be worth trying because MacOS does go silly at times.
Otherwise you can go to one of the retailers like iPowerresale and get another higher spec machine if you want to remain in MacOS.
That’s where I got my second Mac Pro. They seem to have some new in box machines available at the moment as well - which should be eligible for AppleCare. I’m looking at the Mac Studios they have at the moment, those should easily handle Zwift and anything else you want to run. I don’t know what your budget is, if you intend to get another machine.
But try a MacOS re-install first: How to reinstall macOS – Apple Support (AU)

That machine is more than adequate for running Zwift and you should not be seeing that problem.
Thanks. I am fingers crossed for the next 1h20m while new install of Sequoia happens. I’m guessing that this was caused by an update of either mac or Zwift a couple months ago. Thanks @Chris_D9 for the suggestion and resource about iPowerresale and MacPro. The only thing I’m worried about no matter what direction I go is that I’m powering a 4K LG TV as well as a low spec Dell monitor and would love to have both able to run. This is not my everyday computer, just dedicated for the workout room.
Any newer Mac should be easily capable to handle a 4K screen and a second one.
The Mac Studios mentioned are good for running 5K (5120x2880) and 6K XDR screens (6016 x 3384), so your usage should be nothing for those.
Ignore Mac Pro, those are not for your use case. But I was happy with iPowerResale and how easy they were to deal with, especially considering I had a specific requirement for a machine with 28 core Xeon and a W6800X Duo GPU, the GPU which they got new from Apple. Also considering I was an overseas customer so they had to organise special shipping and that went smoothly.
I suspect your issue is a MacOS glitch. I’m not very happy with Sequoia to be honest, it was very troublesome on one of my machines in the early stages.
OK I tried the OS re-install quoted by @Chris_[quote=“Ilan, post:1, topic:637489, full:true, username:Ilan_Eyman_CRYO-GEN”]

Thanks y’all! I followed @Chris_D9 's instructions but the system did not change. Instead I tried going with a “Clean install” with a bootable USB drive using instructions I find on a macpaw web site and it worked! I have not added to the system beyond Zwift and was able to join a pen and put power down with no issue. Thanks everyone! I think I’ll be able to keep the mac mini going for another year at least!
