Apple Seeds Ninth Beta of macOS Mojave to Developers

Apple today seeded the ninth beta of an upcoming macOS Mojave update to developers for testing purposes, one week after releasing the eighth beta and more than two months after introducing the software at the Worldwide Developers Conference.

macOS Mojave introduces a new method of installing software updates, so after you've installed the initial beta using the appropriate profile from the Developer Center, additional betas can be downloaded through opening up System Preferences and choosing the "Software Update" icon.


Apple's macOS Mojave update introduces a systemwide Dark Mode, with Mojave users able to choose between a light theme or the new dark theme, which changes the color of the dock, menu bar, apps, and other elements. Dark Mode is accompanied by Dynamic Desktops, aka wallpapers that subtly change throughout the day. Additional wallpapers were introduced in the fourth and fifth betas.

Stacks, a new desktop organization system, keeps all of your desktop files neat and organized, while Finder has been enhanced with a Gallery View, a Sidebar, a revamped Quick Look option and Quick Actions, so you can do more in the Finder window than ever before.

Screenshots can now be edited using Markup tools and a new management options that also allow for easy screen recording, while Continuity camera, a new feature, allows you to import photos and document scans directly from an iPhone or iPad to the Mac.

The Apple News, Stocks, Home, and Voice Memos apps have been ported from iOS to macOS as part of a multiyear project Apple is working on to make it easier to bring iOS apps to Macs, and Apple has introduced several new privacy protections to keep your data safer than ever.

Apple is also making it harder for websites to track you with a range of new Safari tools, and it's also easier to make and store secure, hard-to-guess passwords for each and every website.

Apple has added an entirely revamped Mac App Store to macOS Mojave that makes it easier to discover apps with a featured section and specific categories for games, creative apps, productivity apps, apps for developers, and more.

macOS Mojave was initially supposed to include a Group FaceTime feature that includes support for chatting with up to 32 people at one time, but it was removed in macOS Mojave beta 7 and the feature won't be available until later in the year.

macOS Mojave is available to developers and public beta testers to work out bugs and other issues ahead of an upcoming fall public release.

Apple has temporarily removed Keynote, Pages, and Numbers from the App Store, just after releasing an update that added iPhone Duo support and a new Intelligent Assistant. It is not clear if the apps were removed intentionally, or if it is a bug. Apple has not said when the apps will be reinstated, but if it was in error, they should return soon.

RIP, MacBook Ultra

Apple today sent out invites for an experience in Los Angeles on Wednesday, October 28, and the "Pro and tell" tagline on the invitation likely means that the rumored MacBook models with touch-enabled OLED displays will stick with MacBook Pro branding instead of the once-rumored "MacBook Ultra" name. The long-rumored "iPhone Ultra" ended up being named iPhone Duo, so speculation that Apple...

Anyone using Mojave on a space grey 12” MacBook? I just wondered how the dark mode mixed with the space grey looks:)

Also those that have downloaded it, how are you finding dark mode? It’s something I’m looking forward to.

Dark mode is fine, I've been using it all of the time since the latest several beta versions.

heres an oldie from feb 2007. its a variation of a theme called v23 I created. Mac theming was pretty popular after OS X first appeared and sadly died out with the release of snow leopard and apple making it difficult to get to the gui parts.
the current os gui resembles a guikit I created in 2006. and v23 even had disappearing scroll bars.
