Updates

• Check OS updates
  • Don't inadvertently upgrade the OS, though!
• Firefox browser (under "About Firefox") --> Updates automatically without prompts
  • To switch to ESR version: 
    • http://www.mozilla.org/en-US/firefox/organizations/all/
  • Browser plug ins (Silverlight, flash, etc.)
    • http://www.mozilla.org/en-US/plugincheck/
• Microsoft Office
• Adobe Flash Player
• MS Silverlight. If still not signed, you might have to run it from the System Preferences => Security and Privacy => "Click the lock to make changes." => Allow apps downloaded from: Anywhere.
  • No need to revert to: Allow apps downloaded from: Mac App Store and identified developers. Just keep it as "Anywhere". (June 6, 2015.)
• And possibly other software
  • Adobe Acrobat, full version. (N.B. Almost no reason to have the read-only Acrobat installed (much less updated) since Mac OS comes with competent PDF reader, Preview.)
  • If Java installed, use Java Control Panel, available through the Java control panel in System Preferences (opens in a separate window).
