A message thread in Apple’s official forums suggest this has been happening since October.
Apple’s macOS High Sierra introduced enough performance enhancements that my dual-core, 2011 MacBook Air felt like it had new life breathed into it. Occasionally, though – and more and more frequently recently – events would cascade such that my CPU would run at full tilt for 5-10 minutes before finally settling in. When that was happening, Activity Monitor and/or iStat Menus would show two system processes chewing up CPU: tailspind and spindump. Thankfully, we now know how to stop that.
No guide can cover every single issue though, and if the problem keeps persisting you’ll want to bring it to Apple’s support team.
Ah, printers. How we hate them; how we sometimes need them. In this Quick Tip, Melissa Holt’s going to wade into the printing morass with a great troubleshooting tip for misbehaving devices. You’ll learn how to visit your printer’s local webpage, and this just might get you out of a (paper) jam. Har har har.
