Apple Seeds Fourth Beta of macOS 10.14 Mojave to Developers

Apple today seeded the fourth beta of an upcoming macOS Mojave update to developers for testing purposes, two weeks after releasing the third beta and more than a month 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 appropriate profile from the Apple Developer Center, additional betas can be downloaded clicking on the Apple in the menu bar, choosing "About This Mac" and clicking "Software Update." Alternatively, open System Preferences and choose the "Software Update" icon.


Today's beta is available for the 2018 MacBook Pro, so those who have purchased one of Apple's machines can now try it with macOS Mojave.

The macOS Mojave update brings a long-awaited 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.

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

Update: macOS Mojave fixes the bug that prevented Dynamic Desktop from working while in Dark Mode, and it introduces a new Solar Gradient dynamic wallpaper option.

I hope this fixes a couple of bugs I am experiencing related to Dynamic Desktop and Login.
Dynamic Desktop seems to be fixed for me with this new version! Now gives you the capability to set Dark mode and use the Dynamic Desktop PLUS Solar Gradients

let me see if I understood correctly. you said that you are going back because dark mode is awful
not only you are the first and only person so far that I seen mentioning that
but I think your case is more that you can't install it yet
dark mode is not an obstacle because you can use the normal regular mode
but for that you have to be able to install it

have you seen Mojave dark mode in any of your systems?
i'm not saying seeing dark mode in youtube videos
how you can judge something that you still haven't seen personally in your own system

me personally, I like many new features that Mojave is going to bring
but my favorite one is dark mode
I installed the betas and i saw it personally on my system
it looks beautiful
at least in my own opinion, you are free to disagree
cheers
I think you may have misread: "going BACK from Dark Mode is awful" - he has a new 15 in pro, unable to install mojave just yet and is missing dark mode running the beta. ;)

It's so good to have the software update at the System Preferences, isn't it?

Always hated the software update at the MAS. That was a mess!

I don't care for dark mode as it's incomplete in my view. I'll stay away from it until all apps including Safari adopt it system wide. You get blinded switching from dark mode to Safari or another app.
fair enough, I understand not everybody like the same thing, we are all different and we have different taste
no problem
:)

thanks for clear things up, I did misunderstood, now is clear thanks to you
:D

Do us all a favour, first read the comment you are about to go on a rant on
o_O
I misunderstood the comment
made a mistake at least I'm man enough to admit it
another user was kind enough to help me understand
you talk about rant and that is exactly what you doing
you said go read the comment
I guess you should do the same thing
go back to my comment and read it again
I wasn't sure if I understood correctly, so basically I asked
"if I understood correctly"
but is obvious that I didn't, I took it the wrong way
another user explain to me what toptekjon meant or tried to say
now is all clear
and it wasn't a rant either
anyway no problem
all good
:)

Hopefully this means public beta update soon. I just got the new MacBook Pro 15, and it says I can't install Mojave on it. Guessing the drivers are not updated yet? Going back from dark mode is really awful :)
sorry man I was so busy today and I came here to get a little break and see what's new
I guess I got all mix up, but now after reading your post again
now that I'm more relax I understood what you wrote
and I do agree going back from dark mode is really awful
sorry I misunderstood your post
I thought you meant you were going back because dark mode was awful
and is really the other way around
next time I will drink some coffee first before posting anything
to make sure I'm reading everything right
regards
