Reducing CPU load and energy consumption of TeXstudio on the Mac

TeXstudio is a decent and free TeX editor on the Mac. One aspect of it bothered me, though: It uses too much CPU for no obvious reason. Even when no tex documents are open, it (version 2.10.8) does *something* very CPU intensive every ~8 seconds. On a desktop computer this wouldn’t be much of a hassle, but on a laptop unnecessary mean wasted energy and less battery life. With TeXstudio on a MacBook Pro it actually means several hours less battery life.

Using the Activity Monitor I found TeXstudio to frequently scan for network interfaces and nearby Wifi networks. That is very odd for a TeX editor and I cannot think of a good reason for it to do so.

Apparently, libqcorewlanbearer.dylib is involved.ย Simple fix: Delete it.

$ rm /Applications/

TeXstudio will continue to work just fine but will use way less energy doing so. Why does this matter? Because it is spring and I want to work outside. ๐Ÿ˜€

  1. Thank you for such a useful clue. I was about to uninstall TeXstudio.

  2. Thanks, I was thinking my MBP’s battery is dying after a year of usage until I noticed that it only sucked when I was writing my thesis. Universe’s way of telling me to work less ๐Ÿ˜‰

  3. Wow! Great advise! TeXstudio is usable now! ๐Ÿ™‚

    Have you reported this as a bug?
