Sofware programs not compatible with Mac's or Window's 7

What is it with all these glucose meter, pump manufacurer and cgm companies and their refusal to use the latest operating systems for downloading info into our computers?  I can understand a bit  not being able to use them with Windows 7 because it came out in October/November(?) but not being compatible with Mac's is inexcusable!  Do we as end users have any way of letting them know of our dissatisfaction with their delay's in not providing updated software for us to use in aiding control of our disease?  Is is because they don't make enough profit?  COME ON! 

I am a bit miffed by this!!!
