It's not the first time my Macbook wakes up and I find it very slow because
suggestd took 6-10 Gb of memory out of 16. Only
kill -9 helps.
I have the latest 10.14.6 Mojave. I am not willing to upgrade to 10.15.
In Spotlight settings, only "Applications" and "Settings" are enabled. There is a very limited amount of them, so it doesn't look like
suggestd is functioning properly.
Can I fix it? If there's no known fix, how do I diagnose what is going wrong?
