It's sad the main new feature of an operating system is dark mode.
As other commenters on this forum have pointed out, users, have been asking for an operating system wide Dark Mode ever since Apple introduced the dark menu and Dock options in OS X Yosemite. Also, the iPhone X may be driving some of this, as certain apps on iOS also have a dark mode and a "black" mode, where by the user isn't seeing a grey value at all, and the pixels on the OLED are simply off to get the deepest possible blacks that an OLED screen is famous for providing. I have read many commenters on this forum who want Apple to implement Dark Mode system wide in iOS as well.
If you are ignoring the other new features in Mojave and singling out Dark Mode to continue the "Apple Sucks" narrative, you're really missing the boat.
- Stacks - I have a couple of co-workers whose Desktops are littered with icons for documents, pictures, et al. Stacks, which are WAY overdue, should help them stay a bit better organized, myself included.
- Gallery View - I have always had a love/hate relationship with the Cover Flow view, I can't be the only one. It is the least used Finder view more myself. I would love to know whether or not others here feel the same way. Gallery View looks 200% more useful for dealing with a variety of files, but time will tell.
- Complete Metadata - This beats Show Preview in the Finder any day of the week and lots more information than a Get Info window and remembering to close the window after invoking it.
- Quick Actions - I don't have an opinion as I am not sure if those things can already be accomplished with a little ingenuity.
- Quick Look - Love it! Many times I have wished I could do something quick and easy in a file I just QL'ed without opening Preview.
- Screenshots - Love it! Countless times I have wanted to make a quick movie of software issue that I have replicated to send to the developer, because screenshots just don't cut it. QuickTime Player is useful, but a lot of the time, it just seems overly cumbersome and complicated to record at the spur of the moment.
- Continuity Camera - I often take pictures on my iPhone that I want to move right over to the Mac and AirDrop is just, well, AirDrop. Which is to say, sometimes brilliant, sometimes a complete POS. I hope Apple fixes AirDrop, but for me, this will decrease quite a bit of friction for many in getting a photo over to their Mac.
- FaceTime - I don't use it much anymore, but it's nice to see they haven't forgotten it.
- News, Stocks, Home and Voice Memos - Welcome aboard! I am excited to see what Apple has in store for users and developers when it comes to moving iOS apps over to the Mac, which I think is Apple prepping us for a move to ARM and/or reaffirming a commitment to the Mac. The Mac App Store is pretty moribund, users want app parity between iOS and macOS, creating a more seamless, lower friction experience. Fingers crossed.
- Under the hood changes in Mojave - Some were discussed, but I have yet to find a comprehensive list. My main concern has been those underlying parts of macOS that have been ignored for far too long. Each successive release from 10.7 to 10.13 has seemed less stable than the one before. HFS+ is creaky and needs a replacement, but the way in which Apple has rolled out APFS on macOS does not inspire me with confidence at all. I only have it running on one MacBook Pro at this time and I really have not been impressed with the speed.
My question for you would be - What improvements to macOS would you like to see Apple make in the future? Are they outward facing features, or under the hood improvements. Is there something in macOS that just doesn't work, or could use enhancements to improve your productivity.
