Ventura 13.2 very slow and unresponsive
I'm finding everything is slow to unresponsive since updating. Safari 16.3 takes a minute to load a page, changing between applications or open documents takes a minute or more, some apps I have to force quit, wireless mouse lags and works unpredictably. Has anyone got suggestions or similar experiences? I've just upgraded from a 2009 iMac and gone backwards. Any help gratefully received
iMac, OS X 10.11
