Is there a current version of Klayout that can run on my Intel 2015 MacBook Pro running macOS Monterey?
I tried HW-klayout-0.29.11-macOS-Sonoma-1-qt5MP-RsysPhb311.dmg but this doesn't open - it only crashes when run (crash report window appears)
Next I tried ST-klayout-0.29.11-macOS-Ventura-1-qt5MP-RsysPsys.dmg but nothing happens when I try to open this version of Klayout.
There are a vast number of *dmg files to pick from. I have no idea what would run on my laptop.

Hi @SRF,
I was able to reproduce the issue with Monterey 12.7.6. It's a bad news.

The reason is simple: the required libraries are not up-to-date in Monterey.
It will work if you don't mind using an older version of KLayout 0.29.6.

Specifically, one of these two is a candidate.
Note that to use option 2, you need to install the Mac command line tools.
If you want to use the latest KLayout 0.29.11, build it from the source.
I have already deleted my Monterey development environment.
Here are the steps: https://github.com/KLayout/klayout/tree/master/macbuild#readme.
The current macOS
build4mac.py
build system does not officially support Monterey.However, I hope it still works.
One important note is that Homebrew should not be your choice, as it no longer supports Monterey.
So, installing Qt5 and other packages from MacPorts is a reasonable choice.

P.S. My machine is an Intel 2019 MacBook Pro.
Edit 2025-02-23:
If you want to use the

./build4mac.py -q qt5macports -r mp33 -p mp312
build command (Fully MacPorts-flavored build), editmacbuild/build4mac_env.py
as below.Hi @SRF,
To reconfirm that the source code build in Monterey is still possible, I set up my Monterey development environment with Xcode 14.2 and the latest MacPorts packages.
Then, I attempted the two builds for KLayout 0.29.11:
Attempt No.1 failed initially with compilation errors.
See https://github.com/Kazzz-S/klayout/issues/46#issuecomment-1370488269 for how to fix the problems.
The attempt No.2 went through without any problems.
I uploaded two DMGs here for your reference.
Please note that I have already stopped providing DMGs for Monterey.
If you want to keep using your legacy machine with the latest KLayout, build it from the source.

Hi @SRF,
I recently upgraded my development environment to
Sequoia 15.5 + Xcode 16.4 + VMware Fusion 13.6.3
. See this ticket.I also noticed that the view count of this post increases gradually.
To reconfirm again that the source code build in Monterey is still possible, I attempted the two builds for
KLayout 0.30.2
with the latest MacPorts packages.I uploaded two DMGs here for your reference.
Please note that I have officially stopped providing DMGs for Monterey.
If you want to continue using your legacy machine with the latest version of KLayout, you can build it from source.

If you want to continue using your legacy machine with the latest version of KLayout (at least up to version 0.30.3) + Monterey, you can build it from source.

I have made another attempt to build version
0.30.4
on macOS Monterey (Intel).I have uploaded two DMGs for the community's reference, which you can find here.

Unfortunately, the latest macOS version,
Tahoe
, no longer supports my 13" Intel MacBook Pro (2019 model).The machine's life is also nearing its end. :-(
