Update 14th March
It appears that 10.4.9 fixes GPS-CS1 support for Intel Macs, but not PPC ones. Please check the comments to see how people are getting on with different Macs.
Well Mac OS 10.4.9 has now been released. I've downloaded the software update, installed and rebooted. Plugged in my GPS-CS1 and... nothing.If anyone out there has had a different experience to me, please let me know. Perhaps it's just because I installed USB logging a while back, or something.
For those Core 2 Duo owners out there who did have GPS-CS1 support - install 10.4.9 at your own risk. It may actually break your support. Anyone in this category who has already installed 10.4.9, please let us know what happened.
Now I know Apple never said that it this work. It was just my hope that since a slightly newer version of Mac OS X 10.4.8 running on Core 2 Duo Macbooks supported the GPS-CS1, then 10.4.9 would add that support to my iMac.
However I have also tried bringing this to Apple's attention. To try to make sure 10.4.9 would fix this Mac OS X bug. I've tried raising it through Apple bug reporter. I've tried asking if it would on Apple forums, only to be told that you aren't allowed to ask questions about unreleased Apple software on their forums, and that my question would be deleted. I understand how Apple uses this secrecy in their marketing, but I'm not asking about secret Leopard features.
I just wanted to know if, six months after this device went on sale, it was ever going to "you know, just work" on my Mac. Like Apple say in their adverts.Like it does on Windows.
