<p>I?d been happily and successfully using OpenSolver in Excel 2016
for Mac OS for about a week and a half. Now whenever I attempt to
solve my model using the same method I had successfully done in
the past, Excel stops responding and the model does not solve or
report an infeasible solution. I attempted reinstalling the Mac OS
package, but OpenSolver is still unresponsive whenever I attempt
to solve my model (or view an error log, or change the engine).
Any ideas? <br>

<p>This is a known problem that we have now noted on the
<a class="moz-txt-link-freetext" href="http://opensolver.org">http://opensolver.org</a> download pages. (Sorry, it was buried in the
comments before.) Specifically, the late 2018 release of Excel
16.16.7 has broken OpenSolver; if any Mac users can help us debug
this, please email us at <a href="mailto:help@opensolver.org">help@opensolver.org</a>.
