Apple Seeds Tenth Beta of macOS Mojave to Developers [Update: Public Beta Available]

Apple today seeded the tenth beta of an upcoming macOS Mojave update to developers for testing purposes, one week after releasing the ninth 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 the initial beta has been installed using the appropriate profile from the Developer Center, additional betas can be downloaded through opening up System Preferences and choosing the "Software Update" option.

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.

Update: Apple has also seeded a new beta of macOS Mojave to public beta testers.

Shame it won't run on my seven year old laptop or desktop. Obsolescence is coming too quickly.

Can’t tell if serious

For all those whining about MacRumors posting this every time there's an update, being on the Public Beta myself, I appreciate the notification because without it I wouldn't know there was an update until sometimes 24 hours after it was released.

I've been using Mojave and for me, its flagship feature isn't Dark Mode, but how polished everything is.

I was able to compare a clean install of High Sierra with a clean install of Mojave and Mojave is definitely noticeably faster on the same iMac. I would usually attribute that to a new install being fresh but both of these were installed on a wiped drive and on the same iMac so it's definitely the OS that performs better. And it's still in beta!

I like most of Dark Mode but I can't live with the dark Finder windows. App icons were designed for a light backdrop don't work really well on a dark screen.

Unfortunately most of the apps I have to use for work like PowerPoint crash upon startup in Mojave.

Check logs. Reproduce issue with new user. Office apps run fine everywhere else.

Does Mojave support AFS for Fusion Drives ?

Yes it does support APFS for Fusion drives. Running it on my iMac 5K. macOS Mojave makes a very polished impression already, everything super smooth so far.

How's the stability of this thing? Thinking of downloading from High Sierra but don't know if I want to risk it yet.


I won't lie... for usual daily driver use, it's solid. You can tell it's nearly ready to release and should be final in a couple weeks. If you have a very specific set of workflows and get weird about the way certain things moved in the past and don't like any change at all, well, any update isn't for you. However, I follow these boards and betas very closely and virtually none of the problems I hear about are something I would normally find unless I made it a point to look for it.

Agreed. High Sierra was a hot mess from the beginning and still is, in many ways. Password prompts lose window focus, contacts syncing doesn't work properly with iCloud despite countless reinstalls/resetting PLIST files on my part, and the entire OS has just been a mess from the get-go. I remember installation (clean install) taking about 40 minutes on my rMBP 2015, while Mojave's installer took 20 minutes (clean install).

IMHO, High Sierra, along with Mavericks, were among Apple's historic worst releases, along with 10.0 Cheetah and 10.0 DP2, as well as System 6 (I think?). I remember the initial release of 10.5.0 (Leopard) not being too hot, either, as well as the infamous hosed 10.2.8 update (Firewire).

Seriously hoping Mojave will bring back the stability of Sierra, Yosemite, Snow Leopard, and Tiger. So far, in the betas, it does seem to be.

GMs are riddled with bugs. The first beta of 10.14.1 is probably more stable.


If you’re worried about stability I’d wait until the actual 10.14.1 is released and avoid betas and the initial release altogether.

Font rendering looks a bit worse to me though, even on Retina displays... Somewhat disappointing that they had to remove subpixel anti-aliasing ('https://news.ycombinator.com/item?id=17477526') :/


I've been turning off 'Use font smoothing when available' in System Preferences / General -- seems to look better imo when in Dark Mode...

According to this, it seems that they should rename macOS Mojave to macOS Vista:
