Check Mac’s Battery Capacity

By ET

When the battery is fully charged, do this in the terminal:

ioreg -l | grep -i LegacyBatteryInfo

If the number following capacity is below 2000, then the battery is quite wasted. Normally, it should be more than 4000.

    I see that a great advantage of Mac is that the hardware and software are integrated together. You probably can write some simple shell scripts to adjust a lot of hardware settings. A lot of cool stuffs can be done. :)

    In US universities, students can get great offers on Mac machines. But I will never choose Mac because Mac OS is one of the worst operating system for software development. A lot of cutting edge software engineering tools are not available on Mac. Whereas software engineering will always be one of my jobs and hobbies. :)

    I choose Thinkpad T-series, Dell desktop computer, and Microsoft Windows. That’s my current taste for computer. :)

    Got an IBM T already. It’s not bad. Apple just has that kind of glamor about it. I bought it for the coolness associate with it.

    It has LaTeX, Perl, MySQL, that’s what I use most, and they are better in Mac than in WinTel. Mac OSX inherited many things from Linux/Unix, so a lot of things are easier to me. Besides the superb UI, it allows me to do a lot of tweaks (not just scripts, the Unix/Linux commands that I’m familiar with).

    Actually, my Mac is based on Intel chips. When you said hardware/software integrated, that was history for a while. With a software called Parallel Desktops, I can run windows on this machine locally. That is: it is not a virtual desktop or simulator. The programs are as fast as they are in WinTel. I use Matlab and SAS a lot, they work perfect on this machine :-)
