Jan 31, 2020  This wikiHow shows you how to enable Flash Player on in Safari and Chrome for macOS. If you're using Safari, you'll need to download and install Adobe Flash Player from Adobe's website. If you're using Chrome, there's no need to install additional apps. Support for Adobe Flash.

Before you start, check the version of Safari running on your Mac. To display the version number, choose Safari > About Safari.

• If your Safari version is 11.0 or later, follow the steps in For Mac OS X 10.11, macOS 10.12, and later.
  
• If your Safari version is 10.0 or later, follow the steps in For Mac OS X 10.10.

Click the Websites tab and scroll down to the Plug-ins section. Locate the Adobe Flash Player entry.


Select a setting to use for Flash Player when you visit other websites.


You can configure Flash for individual websites (domains). Select a website listed in this window, and choose Ask, Off, or On.


Exit Preferences after you finish configuring Flash Player.

Note:

If you are viewing Safari in full-screen mode, mouse over the top of the browser screen to see the menu.

Click the Security tab. Ensure that Enable JavaScript and Allow Plug-ins are selected. Click Plug-in Settings.




From the When visiting other websites menu, choose On, and then click Done.

Check compatibility

You can upgrade to OS Yosemite on any of the following Mac models. Your Mac also needs at least 2GB of memory and 8GB of available storage space.

MacBook introduced in 2009 or later, plus MacBook (13-inch, Aluminum, Late 2008)
MacBook Air introduced in late 2008 or later
MacBook Pro introduced in mid 2007 or later
Mac mini introduced in early 2009 or later
iMac introduced in mid 2007 or later
Mac Pro introduced in early 2008 or later
Xserve models introduced in early 2009

To find your Mac model, memory, storage space, and macOS version, choose About This Mac from the Apple menu . If your Mac isn't compatible with OS X Yosemite, the installer will let you know.

Make a backup

Before installing any upgrade, it’s a good idea to back up your Mac. Time Machine makes it simple, and other backup methods are also available. Learn how to back up your Mac.
