Glad you got it to work. I think if a ChimeraX plugin says it requires ChimeraX version 12.0 then it will not be allowed to install on an older ChimeraX version like the 12.0 release candidates. Tom

Hi Tom,
I just reinstalled the latest version of ChimeraX and it's working now. What a mystery!
Thanks for your help.
Have a good day,

Hi Jean-François,
I don't know why the Install button for ISOLDE using ChimeraX menu Tools / More Tools... does nothing for you. I suggest updating to the current ChimeraX 1.12 release. You are using a 1.12 release candidate and the ISOLDE 1.12.0 version is for the ChimeraX 1.12 release. If that does not help you could download the ISOLDE distribution outside ChimeraX using a web browser from https://cxtoolshed.rbvi.ucsf.edu/apps/chimeraxisolde and then in ChimeraX use the toolshed install command to install the downloaded .whl file.
toolshed install ~/Downloads/chimerax_isolde-1.12.0-cp311-cp311-macosx_11_0_universal2.whl

Dear Sir,
I am having trouble downloading version 1.12.0 of ISOLDE from the ChimeraX "toolshed" (using version 1.12rc202606020412 (2026-06-02), installed on an Intel-based MacBook Pro running Sequoia 15.7.7).
When I click the "install" button, nothing happens.
Is this a bug, or have I missed something?
Thank you for developing the ISOLDE software and for your assistance.
Best regards,
Jean-François Gaucher
