If a software manufacturer CHOOSES to design something for any processing system, they can select the version of IOS (MAC) or DOS (MSFT). If the manufacturer makes that choice because of HELP support on either MAC or MSFT is no longer supported, that is their choice, they could have designed it for an older version. By doing so I feel they support the obsolescence its monetizing profitability for software providers. Soon we will work only to satisfy them.
