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
Apple “Feedback” #12149675. Some netmasks returned by getifaddrs have family of AF_INET yet a length less than sizeof(sockaddr_in), e.g. 5, 6, 7, or 8. On macOS Ventura 13.3.1, at least. It looks like it’s actually allocating only eight bytes for the ifa_netmask (not the 16 that is the size of sockaddr_in per MacOSX13.3.sdk/usr/include/netinet/in.h), as it … Read more
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
A diskutil bug unceremoniously erased an entire hard drive of mine a few weeks back. While I was able to successfully (AFAICT) restore the drive’s contents to it from various backups, the erasure gave the drive a new identity (UUID, specifically). The next time Time Machine ran, it compounded the diskutil bug by also unceremoniously … Read more
This was a fun one. Mail started crashing on launch for absolutely no apparent reason – nothing had changed to its config or similar in a long time. The crash logs were all fingering an identical culprit – -[IMAPTaskManager secondaryIdleMailboxName] called on the wrong GCD queue: Process: Mail [19884] Path: /Applications/Mail.app/Contents/MacOS/Mail Identifier: com.apple.mail Version: 11.3 … Read more
I hate this dialog with the fire of a thousand suns. When this appears, it basically means one (or both) of two things: Some application went nuts and chewed through all your memory and/or disk space. macOS got itself into a darkly comical & embarrassing deadlock. Quitting any of the listed applications is rarely the correct … Read more
I run Einstein@Home, using both CPU cores & my GPU. Other than a few month period where Einstein@Home was issuing broken GPU work units, I’ve been successfully doing this for years, I think. Longer than I can really remember, in any case. It appears, however, that 10.12.2 has introduced some serious issues impacting those GPU … Read more
