SavvyCAN on OSX with PCAN-USB supported???

I believe you are correct, PCAN should be supported across all platforms in QT. However, SavvyCAN doesn't attempt to support PCAN so you won't find it on the list of connections. This should be corrected but so far nobody has had the time or desire to do so. I can't promise any timeline for this feature.

Unfortunately, no, no news. I essentially never use OSX myself nor do I have a PCAN device so it's fairly difficult for me to add support for two things I don't use. I'd love it if someone who did have those things could code up support. But, I unfortunately also don't really know of anyone with the knowledge and hardware to do this. So, I still have no timeline for when support might happen.
