MacOS – Does macOS show battery health for third-party replacement batteries

Sidecar is a nice product for windows and they have a Mac version, but seems outdated (and in fact I found the Mac version via Google, not through their product page). You might want to contact them in case they have something not shown there.

In any case, the graphic card (and CPU power) in the MBAir will have a “hard” time driving “two large monitors”.

If you still want to try, this guy over here is using not two, but three displays (plus the macbook’s display) for a total of four. He has a Macbook Pro tho.

He basically tried the Matrox solution and didn’t like it for various reasons he outlines in the post, so he tried the Diamond BVU195 USB-DVI adapter (he brought two).

Go ahead and read his post, he posts his impressions, problems and even links where to buy the things and their prices. You will surely need a couple of USB Hubs for that.

UPDATE: New products are now available for Mac as Matrox Introduces New Mac-Friendly DualHead2Go DP and TripleHead2Go DP Multi-Monitor Adapters.

The battery cycle is exactly what it says, a cycle. This means that it will count charge and discharge cycles as a whole.

An couple of apple genius guys I talk to recommend at least 2 charge cycles per month, and trying not to leave it plugged in at all times will keep it relatively healthy.

You don't need to completely drain a battery before you charge it either, but the more complete the cycles are, the better accuracy will be on the battery meter.

It's a hotly debated subject, but apple do have information on their website.
