Problem with newer Mac-OS versions

Even when it is reported on the Webpage and in the forums that the version 16.0.1 is working with MacOS 10.12.x, there's often the experience that it is slowing down the Mac and issues with print, saving etc. are reported.
Here is a comment on that directly from PerkinElmer –informatics:
"There seems to be a compatibility issue with newer models of MacBook.  The issue seems to occur specifically on machines equipped with an Intel Iris video controller, but we have also seen a couple of cases with different adapters.
Our developers are already aware of the situation and we hope to have the issue corrected in a future release of the software.
So far the only workaround seems to be, in those cases, to set the zoom level to 75%, but this option is not very comfortable to work with in some cases.
The second alternative for site license customers is to install version 15.1 instead.."

If you already have installed the ver. 16.0.1, then you should uninstall it and get the version 15.1 here:

Please write to Thomas Breitenbach (  to get the serial and the registration number.
