macOS (Apple silicon)

ChemDraft now runs on Windows, and large drawings are much faster to edit, save and reopen.

  • ChemDraft for Windows. The first Windows release, for Windows 10 and 11 (x64). It installs per user with no administrator rights and updates itself after asking you first. Everything you know from the Mac version is there, with Ctrl-based shortcuts.
  • Large drawings stay responsive. Rotating, moving, aligning or deleting thousands of selected objects now takes about as long per object as editing a few, rather than slowing down sharply as the selection grows. Saving is faster, undo history no longer grows without limit, and very large files open again after saving.
  • More of CDXML comes through. Groups and dative bonds in CDXML files are kept, and a file that cannot be opened says why. Damaged or hostile CDXML files are refused safely instead of stalling the app.
  • Keyboard shortcuts fixed. Group, Bring to Front, Bring Forward, Send Backward and Send to Back work from the keyboard again.
  • Plugins read labels as drawn. Condensed labels such as OH and NH2 reach plugins (the NMR predictor included) the way they appear on the page.
  • Faster toolbars at launch. The toolbars appear sooner after opening the app.

Automatic updates are delivered via Sparkle (File ▸ Check for Updates…).

Windows

The first Windows release of ChemDraft.

  • Windows 10 and 11, x64. Installs for your user account only; no administrator rights needed.
  • The installer is not yet code-signed. The first time you run it, Windows SmartScreen warns you. Choose More info, then Run anyway.
  • Updates itself, after asking. ChemDraft checks for a new version at most once a day and asks before installing. File ▸ Check for Updates… checks at any time. Your open drawing is saved and restored across the update.
  • Large drawings stay responsive. Editing, saving and reopening drawings with thousands of objects is much faster.
  • More of CDXML comes through. Groups and dative bonds are kept, and damaged files are refused safely with a reason.
  • Known quirk: the Redo menu item shows Ctrl+Shift+Z; Ctrl+Y works as well.
