Are you still using any Carbon APIs due to a lack of a Cocoa replacement?

@grynspan also just to double-check, you’re not referring to c APIs in general, just Carbon specifically, right?
Jonathan Grynspan ‏@grynspan 17 Oct 2015

@rob_rix Yup. There are plenty of C APIs on OS X that aren't part of Carbon. I'm curious who is still using properly-Carbon APIs.
Michael Tsai ‏@mjtsai 17 Oct 2015

@grynspan Some resource manager and process manager stuff. Also file manager, but I think most or all of that could be migrated.

@mjtsai You should be able to (and should!) move off the Process Manager and File Manager. There are Cocoa replacements for both.
Michael Tsai ‏@mjtsai 17 Oct 2015

@grynspan I don't think there are Cocoa APIs for mounting or unmounting volumes.
Jonathan Grynspan ‏@grynspan 17 Oct 2015

@mjtsai Disk Arbitration can be used for this stuff. DADiskMount() and DADiskUnmount().
Michael Tsai ‏@mjtsai 17 Oct 2015

@grynspan Yes, in theory those will work. Not a drop-in replacement because they're async.
Jonathan Grynspan ‏@grynspan 17 Oct 2015

@mjtsai Which is good because they do heavy I/O, and should be asynchronous. :)

@grynspan I actually had to stop calling FSUnmountVolume on 10.11 because it stopped working…
