A security issue building behind the scenes for weeks has bubbled to the surface, and could lead to performance hits on Macs, Windows PCs, and Linux devices.
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.
The High Sierra firmware also indicates support for Intel’s “Basin Falls” processors, which are high-end desktop CPUs that could power future non-Pro iMacs and Mac minis.
It’s easy to get hardware information about your Mac from “About This Mac.” But the command line data can provide some extra tidbits that the GUI leaves out. John shows you how to reveal detail of your CPU from the Terminal app.
