On December 31, 2014, Mac Rhino will not run on OS 10.7.5.
All installations of Mac Rhino will stop running on OS 10.7.5 on December 31, 2014. To continue using Mac Rhino, please upgrade to OS 10.8.5 or newer (OS 10.10 Yosemite is recommended).
We are working towards a commercial release of Rhinoceros for Mac and completing a number of unfinished tasks. One of those is completing the localization of the application. We are switching to using Apple’s native localization tools and those tools only work on OS X 10.8 and later. Our current translation tools use ad-hoc techniques that I cobbled together to use the translated strings from Rhino for Windows. It does not provide a complete solution, since it leaves all strings that are specific to the Mac in English, regardless of the language setting.
I tried very hard to find a workaround that would allow us to use Apple’s robust localization tools and also continue supporting 10.7.5, but I was unsuccessful.
Also, supporting all OS X versions back to 10.7 means that we are at this point supporting four different versions of OS X, and this has added to our testing load. We’ve missed a number of bugs recently that are specific to 10.7.5 because of inadequate testing resources.
We looked at how dropping support for 10.7.5 would impact our users. In the general OS X user base, about 4% are running 10.7 and almost 90% are running 10.8 or higher. Some users are running 10.7 even though their computer is supported by 10.8 or newer. Anyone who can run 10.8 can also run OS X Mavericks or OS X Yosemite, and these are free upgrades. The rest of the users running OS X 10.7.5 are running on hardware that is not supported by newer versions of OS X. Those computers are at least 5+ years old, and typically older than that.
We regret discontinuing support for any of our users, but we need to provide a great product for the large majority of Rhino for Mac users, and this requires using relatively recent software tools from Apple.
I apologize for this inconvenience (and big problem for those with older hardware). I did search for a way around this problem but could not find one.
We will create one more version of Rhino for OS X 10.7 users, and will set the expiration date of that release to December 31, 2014. This will allow you time to upgrade your OS X version if that is an option for you, or to otherwise decide if and how you want to continue with Rhino for Mac.
If you visit the download page for Rhino for Mac and are running OS X 10.7, you will be redirected to a different web page for downloading this special 10.7 version.
