macOS

macOS is a series of Unix oriented operating systems developed by Apple Inc.. Huygens 25.10 supports macOS 13 or newer.

Installation

1. We are exporting two versions for Mac OS: one for the Apple silicon CPUs (*M1.pkg) and one for Intel CPUs (*.x86_64.pkg). It is essential to download the version that corresponds to the CPU type of your Mac.
2. If macOS blocks starting the installer, select on your Mac: System Settings → Privacy & Security and then click "open anyway". See also "Steps when MacOS blocks installation" below.
3. If you encounter problems to acces files or folders from Huygens on your Mac: System Preferences → Security & Privacy → 'Privacy' Tab → Full Disk access → add new → select your Huygens application.

Older Huygens versions (25.04 and earlier)

Before the 25.10 release, Huygens did not release a native MacOS application, but an X11 based application. In this case, you need to install XQuartz to be able to run Huygens. After OS upgrades, it sometimes is necessary to reinstall Xquartz or to restart the computer.

Steps when MacOS blocks installation

Before the 25.10.0p1 release, Huygens MacOS installers were not yet notarized by Apple. This could cause MacOS to block the installation of Huygens. When this happens, you can use the following steps to still install Huygens:

1. Open your System settings;
2. Select Privacy & Security;
3. Click on "Open anyway".

On other macOS versions these steps might be different, see this article for other versions: Install software from unknown developers
