Hi Oli, Unfortunately it is a bug in Catalina itself, as discussed in this previous post and links therein... <http://www.cgl.ucsf.edu/pipermail/chimera-users/2020-June/016910.html> The only suggestion is to use ChimeraX instead, if possible for your specific workflow.

Hi, After upgrading to Mac OS X Catalina, Chimera now launches a new instance of the application every time I open a new file. Previously, if I for example double-clicked an MRC or PDB file, it would open in the existing instance of Chimera; Now, it launches a new instance each time, which pretty quickly leads to me having 20+ copies of Chimera running simultaneously. Has anyone else encountered this and found a way to revert to the original behavior? Cheers Oli
