Delkin has issued a statement indicating that the CompactFlash and 5-in-1 versions of their CardBus 32 Adapters are not compatible with Mac OS X 10.4 (Tiger).
In the statement, company CEO Martin J. Wood notes that a fix is being worked on, though a firm release date has not been established:
"Delkin is aware of the driver issue for the new Apple OS X 10.4 with the CF Cardbus and our new 5in1 Cardbus adapters. We are currently working with Apple to release a new driver, but cannot set a date for release at this time. We are firmly committed to the Apple platform, and are keenly aware that a great number of our valued Cardbus customers use Apple computers everyday."
