In OSX Yosemite I used to have a bottom row of third party preference applets that contained Java, Flash, Air Display etc in System Preferences. This is no longer showing. How do I turn it back on? (I've spent ages googling but not found an answer).

thanks!bottom row missing

  • You used to be able to toggle certain pref panes on and off in System Preferences' preferences (yeah, I know). Check to see if they have been toggled off some how.

    Try Cmd/L [show all] or View menu > Customize… & a Pro Tip - if you use cmd/shift/4 to take pic, then tap space, you can capture an entire window by clicking it, with a nice drop-shadow… sweet… but it will also stop us wondering whether that dark line at the bottom is a poor crop, or potentially a hidden panel ;)

I installed homebrew http://brew.sh/ and osquery https://osquery.io/. Then did

select * from preferences where domain like "%system%";

which showed a list of preference settings that might be interesting. ThirdPartyCount was 0, which I thought was wrong. So I backed up ~Library/Preferences/com.apple.systempreferences.plist and used XCode to edit the value to 3 (which is the value I expected). After a reboot it went back to zero.

After more googling, I found /Library/PreferencePanes contains third party preference panes. The aliases in there were all broken: because I'd manually deleted browser plugins from "/Library/Internet Plug-ins". So i deleted the really-dead aliases, re-installed Java and now the bottom row is displaying as expected. Thanks for all your help.

(footnote: AirDisplay used to have a prefpane i think but the latest version not longer has it)
