My Mac is Early 2008 and can't upgrade to High Sierra. I am running OS X El Capitan, Version 10.11.6
Model Name: iMac (24-inch, Early 2008)
Processor Name: Intel Core 2 Duo
Processor Speed: 2.8 GHz
ATI Radeon HD 2600 Pro 256 MB
My trash keeps filling up with folders called "Database" and contain Database.sqlite3 and Database.sqlite3-journal
I've seen other threads that have been closed that all refer to Norton as the cause because the problem goes away when Norton is removed. I don't use Safari for web browsing.
