MacOS Sierra ditches Flash for HTML5 push

macos sierra turns off adobe flash by default flashapple
Apple
In the upcoming MacOS Sierra release, alongside the introduction of that lovable virtual assistant Siri, Apple has also made a significant change to the Safari browser: it now turns off Flash by default. With the continuing problems faced by Flash’ weak security, and as it is dropped by more and more platforms, Safari is just the latest to throw it to the wayside.

This isn’t something you can take advantage of now, but when MacOS Sierra launches in the fall with the new version of Safari (10), Flash will be switched off. Instead it will encourage the use of HTML5, which as many sites begin to move over to the standard, means that MacOS users shouldn’t notice much of a difference.

Of course there is still some content, and there are still some websites, that make use of Flash quite heavily, and in those instances, users will instead see a message asking them to install the plugin. This is because although Flash is technically installed, the browser doesn’t let on that it is — as a security check (thanks MacWorld).

Clicking to download Flash will instead direct the user to a settings page which allows them to temporarily “turn on” Flash for the duration of their visit to that site. This is something you will have to do during every visit, to prevent Flash being automatically enabled and opening up potential backdoors to your system.

While this might seem unnecessarily harsh, many other platform providers, including Google, have practically done away with Flash altogether. Major websites like YouTube and Facebook have ditched the standard too, instead opting for the much more contemporary and secure, HTML5.

But Apple isn’t just targeting Adobe software with this new auto-off system; that’s how it plans to handle most plugins in the future. In updates planned for the next year, Apple will be turning off by default plugins like Silverlight, Java, and its own Quicktime in order to shore up the browsers defenses and to reduce website load.

Don’t feel too bad for these platforms though. Most of them are old and even Adobe sees the writing on the wall — it’s been trying to help people convert Flash content to HTML5 for a while now.

Apple fixed one of my biggest macOS gripes with Sonoma — but I still want more
Federighi talking about Continuity Camera.

Apple’s macOS Sonoma update has just been launched and, let’s be honest here, it’s a pretty modest upgrade (probably thanks to the work required on the Vision Pro’s software). Still, when Apple unveiled Sonoma a few months ago, there was one feature that got me excited: Continuity Camera.

This nifty tool lets you use your iPhone as a high-quality webcam. Sure, it actually debuted with macOS Ventura, but this year we’ve got much more control over how it works. Sliders! Toggles! Yes, it’s all here.
