My 2015 MacBook running Mojave has been acting strange lately, especially whilst browsing. Sometimes Safari will freeze up, or reload a page out of the blue. I can feel my computer struggling, so I'm quick to open Activity Monitor to try and see what's going on. Several times now, I've noticed a root process named 'phonetism' at the top, but it usually vanishes before I can read anything about it. Today, I finally managed to get a screenshot of it.
I can't find anything in the activity monitor about the process after it disappears, but I did check the console, where the only results are from ReportCrash, and look like this: However, these crash reports don't appear to have been written at times where I've noticed the CPU problems.
I've tried searching the web for anything related to this, but I'm at a complete loss. Any help or general ideas would be greatly appreciated! Thanks in advance.
