问题 If I have a 32-bit integer BSD device number dev_t (e.g. 0x1000004) on macOS (Darwin), how can I get the corresponding filesystem path for this device (e.g. "/dev/disk1s4")? 回答1: You have to enumerate the mounted file systems and look for one who's device ID matches. You can use getfsstat() for the enumeration. That fills in struct statfs structures. Compare the field f_fsid.val[0] of each structure to the dev_t you're looking for. If they match, then that struct statfs is the one for the

I used nettop on Mac and I see that Docker uses my en0 wireless interface. But, I’m not sure if Docker and xhyve are using the same interface.

问题 We want to make it for users of our (Java) application as easy as possible to send bug-logs to us. First, we imagined to open a bug-report page of our website and prefill an up-load-input field with the path of the file to upload, but this does not work for security reasons. Is it possible on OS X (command line call, Apple Script, what ever) to open a new e-mail in the default e-mail client and add a certain file as attachment? 回答1: Unfortunately there's no standard way to attach a file; you
