CCDC Software and macOS


We are pleased to confirm that the CSD Portfolio is now supported on macOS 12 Monterey, 13 Ventura and 14 Sonoma.

Note: Apple ARM-based (M1) systems are supported via emulation with Rosetta 2, but with the caveat that there are some issues with certain functionality as detailed below. We plan to improve support with subsequent releases.

To obtain the latest version, please download and use the full CSD installer. Links for this can be obtained via https://www.ccdc.cam.ac.uk/support-and-resources/csdsdownloads/

Known Issues with Apple Silicon (M1) chipsets

  • Aromatics Analyser and POV-Ray image creation are not compatible with Apple ARM-chipsets
    The Aromatics Analyser and POV-Ray functionality in Mercury are currently not compatible with Apple ARM chipsets and are not supported. All other functionality should work correctly with Apple ARM chipsets. We plan to improve support for these chipsets with subsequent releases.
  • Starting programs on Apple ARM chipsets (M1) for the first time has a delay
    When running on Apple Silicon via Rosetta 2 emulation, it is normal that the first time a program runs, it takes extra time to start, usually in the region of 15-60 seconds. This delay no longer occurs the second time you use the program.

Other Known Issues on both Intel and Apple Silicon-based macs:

  • On macOS, ConQuest may occasionally not display interface elements correctly
    On macOS, ConQuest may sometimes open an interface panel and not properly render all of its elements correctly. If this happens, closing and re-opening the element should resolve the issue.
  • ConQuest is not compatible with dark mode in macOS
    ConQuest will not change its display in macOS dark mode but will instead use the same display as found in standard display mode.
  • Labels in images saved from Mercury on macOS may be too large
    Labels in jpg or png files saved from Mercury on macOS may be too large - this issue is sometimes resolved by the use of an external monitor.
