When a user encounters an online video on a Mac or browses to some Web site, it always shows that Flash is out of date and needs to download a new version, but you don't see any updates on the Adobe website. Originally for security concerns, Apple has shielded all versions of Adobe Flash player plug-ins remotely from the Mac OS x system. Including the newly released 16.0.0.235, as well as older versions of 13.0.0.259, are in the screened list. When users access Flash content using Safari browsers, they will receive prompt information such as blocked plug-ins, flash security warnings, flash expiration, and so on.
This means that users cannot view Flash content through Safari. When users use the Safari browser to access Flash content, they will see the plugin blocked, flash security warning, flash expiration and other prompts. Of course, many users do need to use flash plug-ins, such as micro-trust public platform upload Pictures, see Youku and so on, download other browsers can use, but I am accustomed to safari, in fact, simple settings can still be used. Apple will also require users to download a new version of Flash Player, but in fact Adobe has not released any updates, so users either give up watching flash or risk security.
Because the Web page running Flash can cause many problems with Macs, such as: Fever, wind speed, security, etc., so you want to see in Flash must accept these, this is the reason Apple abandoned flash. So if you want to continue using Flash on the Mac, you can use other browsers, and of course Safari's loyal users can also be set using, how to set:
1, when I was looking at Youku or the public platform to add pictures, the page shows that Flash has expired:
2, open Safari's preferences:
3, find the Security menu under the Internet plugin, allow the plugin default are tick, click to open the Site settings.
4, look to the left of the figure below to find the plug-in class purpose Adobe Flash play:
5, to find the site you want to use flash, for example, I want to add a picture in the micro-trust public platform, that in the right-hand option bar select Always run, and then click on the bottom right corner of the finish.
