I just downloaded the education version of ArchiCAD 21 on my Mac and it won't open - with El Capitan or Sierra OS. It crashes every time - I've uninstalled, and reinstalled with no luck. I've also run updates. I previously ran the education version of ArchiCAD 19 on El Capitan with no problems for nearly a year. <BR /><BR />Any help is appreciated!</DIV> Wed, 06 Mar 2024 09:53:39 GMT Anonymous 2024-03-06T09:53:39Z https://community.graphisoft.com/t5/Installation-update/ArchiCAD-21-won-t-open-El-Capitan-and-Sierra-OS/m-p/257554#M26913 <DIV class="actalk-migrated-content">Hi all - I'm a new forum member, but have used Archicad on and off for a few years.
