Question

Answer 1

Thanks for all the replies.
I've now installed the ad blocker, thrown away the unwanted files, and thrown away a copy of Firefox that Adware said had a problematic extension.
Things are better, but still slow.
Activity Monitor shows that with just Mail, Chrome and Excel running, 2.9GB of my 4GB RAM is used. Opening InDesign (always slow) increase that to 3.2GB. But the graph stays green.
Console shows several potential problems but I don't know if any are significant. In any case I will call my Mac store tomorrow to ask their advice about RAM.
