Known Issues with Apple Silicon (M1) chipsets

  • Aromatics Analyser and POV-Ray image creation are not compatible with Apple ARM-chipsets running macOS 11 Big Sur
    The Aromatics Analyser and POV-Ray functionality in Mercury are currently not compatible with Apple ARM chipsets running macOS 11 (Big Sur) 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.
