If I leave USB-powered devices plugged into my MacBook while it’s charging, will it degrade the battery? What I’m trying to figure out is if the USB devices will drain the battery and then the charger recharges the MacBook repeatedly, or do the USB devices consume power directly from the MacBook...

Hello, I when I walk away from Mac, it appears to disconnect networking, how do I fix this bug? There is no way Apple or any company would actually program it that way on purpose, that would be the worst feature I have ever seen in any operating system including Win 3.1. I only use ethernet...

Anker’s 120W GaN Charger Disappoints with Type-A Port Hey everyone, I did not purchase the 120W USB-C Charger, Anker 737 Charger (GaNPrime), and 3-Port from Anker, because I was disappointed to find out that it has a Type-A port instead of a 3 Type-C port. If you want to learn more about this...

Curious as to whether the position of HD/SSD sleds makes any difference between slots one, two, three or four? The presence of a non-bootable—and also unrecognised 8TB HD—in the left-most position, on start-up appeared to prevent the machine from advancing beyond the chime, despite the presence...
