getifaddrs never specifies broadcast addresses

Apple “Feedback” #12149764. According to man 3 getifaddrs: The ifa_dstaddr field references the destination address on a P2P interface, if one exists, otherwise it contains the broadcast address. In my testing the ifa_dstaddr field is never non-null. I’m not sure I have any suitably configured P2P interfaces, but I definitely have interfaces with broadcast capabilities … Read more

In any from that day. Where I was outdoors for hours in a flat grass field. I then discovered that … Read more

iCloud ‘Optimize Mac Storage’ breaks the Mojave installer

Yet another example of a really bizarre macOS bug that’s pretty inexcusable as a test escape, given it occurs with the default installation settings on a completely clean OS install. In short, the Mojave update installer does not work (on High Sierra at least) if you have ‘Optimize Mac Storage’ enabled for iCloud Drive (System … Read more
