F.lux is installed on an iMac (OS X 10.6.8, snow leopard) and the location has been set up correctly but the programme won't open. When I open Activity Monitor, f.lux shows up as a running programme and appears to be using a small % of CPU, but in my dock there is no dot underneath the app icon, which implies that the programme is not currently running. When I right click on the app icon it shows me the option to open the app even though Activity Monitor thinks it is already open. When I select 'open' nothing happens.

QUESTION: I need to use Mac OS X 10.6.8 in order to run software not supported in later versions of OSX. I cannot succeed in installing the new versions of Flash Player in the Mac mini I need to use for this work. I have successfully installed the version 14 flashplayer on 10.9.3 systems running. A word of caution based on my recent experience. I've been using a Canon MF4200 series on my MacBookPro with system 10.6.8 since forever. The Canon Mac URFII driver is required to make this multifunction printer work. And it does, quite nicely. I recently reinstalled Mac OS X on my iMac to Mac OS X 10.6.3 then updated to Mac OS X 10.6.8 and now I am trying to update to OS X El Capitan but when I go to the App Store to download, I click the 'GET' button and nothing happens. Nothing also happens when I try to do this with any other apps.
