Hello guys,

I'm running Chemdraw 16 on my MB Pro 15" Late 2016 and I noticed several performance issues. For example the drawing of molecules is very slow and laggy. In addition to that, CD crashes sometimes. I think the problem occurs, when I change the page setup to a bigger format, for instance from A4 to A3. Other bigger formats than A4 are also affected by this issues.

Has anyone any idea, how I can solve this issue?

I tried several things, which did not solve this issues:

-reinstall CD

-restart the Mac

-disable the switch between integrated and dedicated graphics in the system settings.

-disable antialianising

Are there other things I can try?

Thanks for your help!

I have been experiencing the same. ChemDraw is super slow on my MacBook Pr 13-inch, 2016 (macOS Sierra). I tried everything that you did but none could resolve the issue. Any help will be greatly appreciated.

Thanks,

Puuuh, thanks, I'm not the only one with that issues.

I got an answer from the customer support and the guy there told me, that this is a known issue and is only related to the newest Macs. An Update should solve this problems. So please hold the lion and stay tuned.

I observe the same issue on my MacBook 13" late 2016. Prette bad performance in larger documents, no way of productive work. Reply of the Support Team said I should zoom to 75 %. Obviously drawing molcecules at that zoom is preety difficult. Contact to support already 4 weeks ago and still no fix! Cant imagine that the issue is too difficult to solve, they just dont take it sirious enough because it just relates to some newer mac mashines. For such expensive product definetly unworthy!

Preety bad service CambridgeSoft!!!

That's exactly what they told me to do and as you I don't want to draw at a zoom of 75%. Actually I prefer to draw at 150%. In my case the support gave me version 15.1 where the drawing itself is almost ok now, but I don't have access to several menus for example the document settings. I'll report this to the support and stay in contact to them for updates.

It even does not work faster with the highend late 2016 MB Pros. Just sad.

Same problems with me. I found that when I changed document type to Poster (doc settings > layout, I could edit faster even at 150%. Maybe playing with bond lengths and widths and other settings would help - then the structures could be shrunk in whatever document they're destined for.
