Ironically, SMART is one of the dumbest, least likeable tech companies around, but unfortunately I’m responsible for quite a few of their interactive whiteboards.
So when they decided to force everyone to upgrade to their not-smart subscription-licensed “SMART Notebook 14” by leaving the previous version broken on OS X Yosemite, I was in a bit of a pickle.
Thankfully, a bit of determination (a.k.a. trawling through crash reports and Google results for “yosemite ruby 1.8 HALP PLZ”) was all it took to figure out that getting Notebook 11.4 working on Yosemite is as easy as copying Ruby 1.8 from a Mavericks machine over to Yosemite.
/System/Library/Frameworks/Ruby.framework/Versions/. I just tar’d the 1.8 folder up and copied it over.
