Hey Guy - Mac OS 10.8, Mountain Lion is a brand new OS just released last week. It's Canon's responsibility to keep up the the OS, not Apple's. Apple had three month's of developer previews and Canon had ample time to upgrade the EOS utility to work with the new OS. And, BTW, do you think that windows 8 will work with the EOS utility out of the box? Let's keep this civil, and not throw stones at the wrong guy
I could say it's just as much Apple's responsibilty to make sure software works with a new release. What is so different in Mountain Lion that a basic program like EOS Utility needs an update to work. Ever heard of backward compatability? Or is that forgotten because it's Apple?
As far as upgrading versions of Windows and software issues, sure they happen, but just as often you can reload old software with 0 updates needed. I currently have several programs/games that I have run on Win XP, Vista 32/64 and 7 32/64 with no updates or hassles. I have old peripherals that have not had driver updates since before Win 7 was released, but they work just fine with older Vista drivers.
It can be done, Apple just chooses not to.
