Hi, Someone posted a quest about OS9 Bluetooth, I read this thread and am posting to save time of the apple core user base. Be advised by apple documentation about bluetooth OS9. The only known apple approved bluetooth device is the DBT-120 Dlink which appears currently out of stock in the uk as stated by dlink to me on the telephone as or the time of posting 2009 Nov. Other bluetooth adapters are in d link range, currently uncertain and untested use with os9. Os 9 forever site posts a control panel and source code is available for os9 as a driver, this pack of source is a) an unfinished project and b) requires metroworks code warrier not macintosh programmers workshop to compile, the source is not documented, no instructions are available for porting to compile with MPW, and the package ostensibly presented as is, only the control panel works as a compiled binary, and without the driver, just sits as a front end gui control panel without much else occuring. Sorry to be vague, but these are facts not fiction. Dlink 120, as apple support and sales suggest, requires the firmware update to use with mac os 9, apple support and d link support, advise me that the blue and grey unit in the preferred unit to purchase for os 9, if you can find someone who has stock and can sell. Avoid IVT bluesoile dongles as they just present driver not found, and the mac os just sits looking online for the driver to install, nothing occurs in finding it, france ivt said they will not support mac as they offer windows only solutions, that was 2006. Recently china hq at ivt said they might consider the option an put it to the board, but as yet their support people have not be able to acquire the code necessary to complete the package, ivt bluesoile for mac os 9 and above. What appears to me to be the facts is that third party product developers seem to expect apple to produce drivers for their product. I know the efforts it takes to build a driver for a product which can take even the best apple team of dev up to 6 months. On the other hand, if an apple dev team does spend time on producing a solution, they have to make some thing out of it to justify the time. Bluetooth support came with x later because apple spent time on providing the solution. This done, it appears that third party product people are content to rest on their laurels and not provide drivers themselves because, they argue, Apples solution exists already. It is an age old chicken and egg situation whereby third party companies provide only solutions offered by apple themselves, I don't think apple is in a position to offer everyone who produces a device, free development time to produce a driver for their devices. It is 3rd party developers responsibility to provide drivers for their devices, themselves, or, to pay apple their license fee to distribute the apple solutions provided by apple, as part of their product. That is the state of play of bluetooth support for os 9, in facts. The D-link bluetooth device is the solution offered by apple for os 9 people, that is what apple have posted in the past, there must be a reason for this, an that is probably the matter of licensing issues, ie dlink support apple. Don't waste your time trying to challenge the position, of find a work around yourself, when you hit a brick wall on a problem, like I have done, it is for a good reason, that reason is dlink support apple for os 9, no one else out there can be bothered. DBT-120 is the established solution. Good luck David
