I've installed macOS sierra public beta on my secondary mac, an 21 inch late 2009 iMac. Beta 1 didnt have any significant problems, general performance (opening applications, browsing, itunes, etc) was satisfactory but since i've installed the public beta 2, i've had a significant drop in overall performance (finder taking 3-4 mins to open after boot-up, safari ultra slow, some apps won't opening at all).
Anyone else having this performance issue? I wonder if it's an issue specific to the late-2009 iMac
