Adobe Flash is used for certain content on websites—usually video or web apps. While it’s slowly being phased out in favor of HTML5, occasionally a website still requires you to have the Flash player installed. It’s not installed by default on macOS anymore, but you can still download it.

Adobe Flash用于网站上的某些内容，通常是视频或Web应用程序。 尽管它逐渐被HTML5淘汰，但有时网站仍然需要您安装Flash Player。 默认情况下，它不再安装在macOS上，但是您仍然可以下载它。

Warning: Do not download Flash from anywhere except Adobe. It’s a common phishing tactic for a malicious website to claim your Flash player is “out of date” and direct you to a fake download. You should only download Flash from Adobe’s official download page.

警告： 请勿从Adobe以外的任何地方下载Flash 。 恶意网站声称您的Flash Player是“过时的”并将您定向到虚假下载是一种常见的网络钓鱼策略。 您只能从Adobe的官方下载页面下载Flash。

安装Flash (Installing Flash)

Flash comes packaged in a DMG, and they have separate versions for different browsers. Choose the browser you use, download Flash, and open it up. There should be a single installer to run, and all you’ll have to do is agree to the Terms and Conditions and enter your Mac password to allow the installation.

Flash打包在DMG中，并且为不同的浏览器提供了单独的版本。 选择您使用的浏览器，下载Flash，然后将其打开。 应该只有一个安装程序可以运行，并且您要做的就是同意条款和条件并输入Mac密码以允许安装。

The Flash installer will ask you how you’d like the program to update—automatically, manually, or with a pop-up like most App Store apps use. Since Flash is known to have had a rough history with quite a few vulnerabilities, it’s probably best to update automatically.

Flash安装程序将询问您如何自动，手动或像大多数App Store应用程序一样使用弹出窗口来更新程序。 由于已知Flash的历史悠久且具有许多漏洞 ，因此最好自动更新。

手动更新Flash (Updating Flash Manually)

Flash will add a new preferences pane in the System Preferences, from where you can configure the local storage and camera settings, as well as manually check for updates. Under “Updates,” you’ll be able to reconfigure the options you selected when installing, as well as manually check for updates by clicking “Check Now.”

Flash将在“系统偏好设置”中添加一个新的偏好设置窗格，您可以在其中配置本地存储和相机设置，以及手动检查更新。 在“更新”下，您将能够重新配置安装时选择的选项，以及通过单击“立即检查”手动检查更新。

If Flash is out of date, it will automatically download an up-to-date version.

如果Flash已过期，它将自动下载最新版本。

After everything is installed, you’ll still want to make sure Flash is configured properly in your browser, particularly where security is concerned, because running any random Flash app (usually found in malicious advertisements) can subject you to malware. We also recommend enabling click-to-play, which will only run Flash apps that you manually approve. You can read our guide on click-to-play for each browser to protect yourself.

安装完所有内容后，您仍然要确保在浏览器中正确配置了Flash，尤其是在涉及安全性的情况下，因为运行任何随机Flash应用程序(通常在恶意广告中发现)都可能使您遭受恶意软件的攻击。 我们还建议您启用点击播放功能，该功能将仅运行您手动批准的Flash应用程序。 您可以阅读每种浏览器的点击播放指南，以保护自己。
