It is our intention to discontinue all official support for OS X 10.3 in the near future. When this happens, while we will not intentionally break our products on that platform, if it is not possible (even via CDMaker) to use them we will not consider this to be a bug and instead will ask customers to upgrade to a newer release of Mac OS X. Additionally the system requirements on our website will be updated to reflect this change.

We welcome feedback from any affected customers on this issue, though we do note that the reason for dropping 10.3 support is that it is a significant extra testing and maintenance burden and we believe that relatively few customers will be adversely affected by the change.

Note that, of course, anyone already using our software on a system with 10.3 will be able to continue to use the versions that they are presently using; the change will only apply to new releases.
