I just updated my operatine system to Big Sur. My ChemDraw 15 can not be opened. Any advise on updating the ChemDraw 15? Thanks.

ChemDraw 15.0 not compatible on macOS Big Sur 11.x.

The highest compatible Mac OSX for our v15.0 is Mac OSX 10.10 and for v15.1 is Mac OSX 10.11.x.

Please note versions prior to 20.x are not supported with macOS Big Sur 11.x and above. Also from November 2020, version 16.0 as well as versions prior to 16.0 are in the End of Life phase and no longer supported.

You will find the compatibility information of our products and system requirements from the following FAQ.

So we recommend to upgrade to the current version. You can obtain a fully functional 2 week evaluation version of the latest version of our products from our web site at:

You can try this trial version and confirm yourself before opting to purchase.
