Ever have an iOS device that won’t stay connected to your Mac? How about needing to connect your Thunderbolt 2 devices to your new Thunderbolt 3-equipped Mac? What about proving your location in the past? Or looking up phone numbers?
These are just a few of the questions John and Dave tackle this week. Of course, Cool Stuff Found and Quick Tips are healthily represented as we drive towards the end of 2019. Just make sure to avoid RISCy behavior. Or don’t, and be like Chuck Peddle!
Safari 13 is adding a CPU Timeline to Web Inspector. This lets web developers measure the CPU usage of a page, energy impact, and more.
Traditional methods to estimate power/energy usage of the processor has always been a cumbersome task that included special purpose tools or instrumentation on the platform along with third party equipment. Intel Power Gadget is supported on Windows and macOS and includes an application, driver, and libraries to monitor and estimate real-time processor package power information in watts using the energy counters in the processor. In version 3.0 there are more features that include estimation of power on multi-socket systems as well as externally callable APIs to extract power information within sections of code.
Geekbench results posted this weekend appear to show an upcoming MacBook Pro featuring the latest 6-core Intel processor and 32GB of RAM, a major upgrade over the current 4-core models limited to 16GB of RAM. This suggests that a 6-core MacBook Pro could make its debut this week at WWDC.
Dave Hamilton and John Martellaro and join Jeff Gamet to look at what’s coming in Intels next generation processors for the Mac, plus Dave explains network buffer bloat and why it matters.
macOS does this with App Nap, but only when an app window is covered by another window.
The report is attributed to unnamed sources who said the project is codenamed Kalamata, which is both a city in Greece and an olive variant.
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.
