Hi, I appreciate this might seem an odd request, but do you have a public download location for ChimeraX software? There exists a widely used system by which administrators of Apple computers distribute software to their users by means of applications known as Munki and Autopkgr. Software which can be downloaded from public websites can be managed in such a way that new releases and updates are automatically added to the software repository Apple administrators curate for their users. Without making this publicly available, admins will only update your software when users request the admins to do so. Looking back on the Loupe Browser instances that have been made available to my users, they have only had access to versions: 0.8.0 0.9.0 0.9.1 0.93.0 1.1.1 1.7.1 and today they will have 1.9.0 If your software was made available via public download by a predictable URL, then they would have had access to every version released on the day it was added to your website since it was first requested by users. If you are concerned about the acceptance of terms of conditions then perhaps this could be incorporated into the URL string. Regards
