After the EFI security update and firmware update, I get an occasional spinning ball when scrolling.
Yesterday I installed the MAC EFI security firmware update and the 2015-005 security update. Now, when I'm scrolling up and down a page or put my curser on a link I get a momentary spinning ball. It's annoying, not locking up or anything. And when scrolling, it can cause the page to overshoot where I was scrolling to... This only seems to be an issue in Safari and particularly with Facebook. There seems to be an issue with the updates. This didn't happen before the updates yesterday. I use Mavericks 10.9.5 on a 2012 MAC mini. Lots of RAM; 16 gigs. A 240GB SSD. Anyone have any ideas what is the issue? Or if this is something I'll have to wait for Apple to address on the next update? Thanks.
