<p style="color: rgb(0, 0, 0); font-family: arial;" class="">Firstly, several users have reported a bug related to our pyqtgraph plotter, that ends up crashing with e.g.</p>

<p style="color: rgb(0, 0, 0); font-family: arial;" class="">If you are in this situation, replace your plotfuncs.py with this new version: <a class=""></a></p>

Secondly, if are on a Mac and upgrade to macOS 13 Ventura (intel/x86_64), your already installed Python tools of McStas/McXtrace and /Application bundles may not work after the upgrade.
<p></p>
<p style="color: rgb(0, 0, 0); font-family: arial;" class="">A workaround is to:</p>
<ul style="color: rgb(0, 0, 0);" class="">
<li style="font-family: arial;" class="">In a terminal, start your “McStas or McXtrace shell" (e.g. run mcstas-3.1-environment, /Applications/McXtrace-1.7-environment.command or /Applications/McXtrace-3.0.app/Contents/Resources/mcxtrace/3.0/environment)</li><li style="font-family: arial;" class="">Issue the command
<pre class="">export PATH=$MCSTAS/miniconda3/bin:$PATH</pre>
