How laptop Apple silicon Macs help prevent attack by malicious USB and TB devices using Accessory Security, and why some of them also have liquid detectors in their USB-C ports.
How to create a custom preset to use for your display’s colour profile, how you can make use of measurements of a colorimeter, or adjust white point by eye.
Apple silicon laptops start up (if not asleep) when you open their lid or connect power. Now you can change that behaviour by setting their NVRAM.
Some services can only be run when a MacBook Air or Pro is awake and running on mains (AC) power. Here’s a list, and what you can do to ensure their work still gets done.
1989 Mac Portable, lead-acid. 1991 PowerBook 140 & 170, NiCad. 1992 PowerBooks with NiMH (3 types). 1995 lithium ion. 2006 MacBook Pro, lithium polymer.
History from Mac Portable’s lead acid to the latest lithium-polymer. But how should you manage your Mac’s battery? What about when in storage or heat?
How much faster are P cores at running the same thread as E cores, and how much more energy do they require? And how do they compare with using the GPU?
What to do with the Mac that either won’t go to sleep at all, or keeps waking up and discharging its battery? It’s pmset or Sleep Aid.
Discovering why a Mac wakes up when it should be asleep, and quietly flattens its battery overnight, has been almost impossible, until now.
