@cstross I had an older mac in which i ran adobe cloud for all of a month (to touch up one file in illustrator) and I could not get rid of it. I uninstalled it and it was still there. I deleted all the files including the sneaky ones and they all came back. Occasionally it would go nuts and eat the disk or all the memory. I ended up having to wipe the whole machine to get rid of it. I used illustrator for 30 years. Never ever, ever ever ever again.
