I am a big fan of BaseCamp, too, and this is news to me that it is no longer being supported. Bummer. To whomever is having MacOS problems: Are you running better than 10.10.5? Yosemite? I have no problems other than it being slooooowwww.... That said, it's just one more reason not to jump on the "technological progress" bandwagon. Pick one computer your family owns, maybe the oldest one...and stop updating your hardware and software. Keep an old computer around, running an outdated OS, that still has an optical drive to read and write CDs, DVDs etc. It may serve you well later. Not to mention this is the only way to read the service manual for my Bavarian Mechanical Wonder.
