Archicad 28 laggy and slow to response with updated macOS Tahoe

Rolla1702 — Sun, 26 Oct 2025 23:25:26 GMT

Archicad 28 is experiencing significant performance issues on macOS Tahoe (on M1 Apple silicon iMac) with constant lags and very slow response times. The software worked without any issues on the previous macOS version.

Could you please inform us about when we can expect an update or fix to address this compatibility issue?

Thank you

Operating system used: Mac Apple Silicon Tahoe

I’m running Archicad 28 and 29 on Tahoe and haven’t noticed any performance issues. Is your Archicad 28 fully up to date? How long ago did you update to Tahoe?

Hi Lee

Yes Archicad is up to date, version 28.3.0 (6003), I updated to Tahoe about 2-3 weeks ago and since then Archicad have been very slow in response times.

Thanks for your response

/AC/29/SPA/Archicad-29.0.0-SPA.exe not found

This is what I get when I want to download ArchiCAD 28 and 29. But I already installed ArchiCAD 28 before.

This has nothing to do with Archicad running slow in Tahoe.

Please create a new post or find one similar to discuss this issue.

I assume it’s slow across all projects you open and not just one?

Yes, that is correct. I have tried multiple files, and they are all slow to respond.

Do all the files use the same Libraries or anything loaded in from network shares or anything like that? Any Libraries other than those out of the box?

There could be something different to how Tahoe is dealing with network shares upsetting Archicad.

please tell me, do your visualizations work in Archicad 28 in the Tahoe system?

Do you mean Cinerender?

@Rolla1702 is there any chance that you accidentally installed the Intel version of 28 on your Apple Silicon Mac?

Yes, that's right! I have Archicad 28 and macos Sequoia 15.7.2 installed, but the Cineware Maxon visualization does not work, I want to try updating macos to Tahoe, I'm worried if the Cineware Maxon visualization will work? If she works for you, she should work for me too. I make visualizations directly in Archicad.

I know nothing about MAC OS, but maybe this will help.

I also encountered this especially if I have several archicad versions opened eg. 27,28,29 reason is working with different projects simultaneously. Working with a master plan project but am only using slabs and wall and zones not going into details yet but really zooming in zooming out it will take an amount of time that shouldn't happen.

Wondering if something is not working right or am I doing something wrong... 😒

This might have something to do with Electron in Tahoe, see here:

This little utility showed the following apps as potential sources of slow-downs:

❌️ BIMcloud Server Configurator.app (24.3.0)
