You can now sort your documents in Finder even when you have the grouping feature turned on. (For example you group the download folder by filetype and files inside the group are sorted by name)


Safari tells you when a tab crashed

Whilst Safari has always been able to restart crashed tabs, now it tells you when it's done so:

  • Now that is both cool and useful to have.

Now you can see which all apps are using your location. And you will also a new Privacy tab in Security & Privacy in System Preferences :

Messages (iMessages) can be created quickly in Notification Center


Using Speakable Items and Automator To Command Your Mac By Voice:

The Unofficial Apple Weblog (TUAW) uses an automator script and the new "Speakable Items" option in Mavericks to achieve this:

System Preferences > Accessibility > Speakable Items to launch apps.

When it's set up, you simply hit a key on your keyboard, speak a phrase, and that launches the apps you choose.

Their example is a simple "Good morning" to start your day.

There is a list of preprogrammed things you can say to command your Mac as well.

They have a video tutorial which takes you through the various steps.


Fairly certain that System Preferences has had some visual tweaks, including larger text and icons. There's a new iCloud icon too.

Edit: As per comments, the category titles have been removed.

    They removed the category titles from each section, too.

LinkedIn and few others are now supported in Internet Accounts :

Automatically Installs Updates

My favorite feature is the ability to have updates install automatically in the background just like they do in iOS 7.


Charging state of an iPad is notified to the user

Because of insufficient current on some Macs, especially older ones or because of USB multipliers, iPads can't get charged or they only get charged when their screen is idle.

Of course, Mavericks can't fix this situation, it's basically an electrical problem but it seems that Apple now made it a little bit more manageable by notifying the user through a Notification Center message if their iPad is not being charged when plugged to their Mac.

enter image description here

  • I had no idea that some Macs could charge iPads - charging works with Retina Macbook Pro late 2013.

Activity Monitor tells you what pages a Safari process has open

If you mouseover any Safari subprocess in Activity Monitor you can see what pages are loaded in the process in the tooltip.


Full screen finder:

Pretty simple, but really nice.

  • … and apparently no hotkeys for switching between tabs? I thought the whole point of tabs here was that they behave exactly as in Safari … Commented Oct 26, 2013 at 14:26

    @KonradRudolph cmd + shift + { works for me

  • @fuadksd So it does. I could have sworn that Safari has a different combination. Still kind of annoying that there’s no agreed-on standard, so that all other application use different keys (in particular Firefox, Chrome, Opera using ⌘+⌥+arrow keys (EDIT: I just realise that they also support Safari’s style). Commented Oct 28, 2013 at 13:50
  • It supports both cmd + {|} and ctrl + shift + tab. Those are supported by safari, and I think, they're like, Cocoa standards.

Finder Tabs

Safari Style

  • Command + T opens a new tab (as it does in Safari)
  • Right click (or control + click) a file or folder within a finder window > "open in Tab"
  • Control + Tab to cycle through each
  • Bunch of open Finder windows? Window > "Merge all Windows" to neatly arrange into one Finder window with tabs.

The Mail.app for Mavericks supports exporting emails now as PDF files, which is useful. Although if attempting to export multiple emails as PDF, it will simply generate multiple PDF's rather than appending one large PDF file.


Disable Mavericks Spelling Autocorrection:

If you get frustrated when OS X 10.9 attempts to autocorrect the multiple technology words that it doesn’t recognize. You should be able to disable the autocorrection feature either globally or on a per application basis.

In theory you should be able to disable it globally or disable it only in certain applications. I have not found that the global disable actually seems to turn off the corrections in all applications though. this is most probably a bug that will be fixed in future Mavericks updates. It is helpful to disable it only in specific applications anyway.

Disable Spelling Autocorrection in all Applications:

  • Select Keyboards under System Preferences.
  • Under the Text tab uncheck correct spelling automatically.

Disable Autocorrection for a Specific Application:

  • Open the Apple application that you want autocorrection disabled.

  • Right-click (or ctrl-click) into any text field. From the context menu that appears, under Spelling and Grammar uncheck Correct Spelling Automatically.

enter image description here

Remember that various applications can handle spelling correction in multiple different ways. Many applications will maintain the consistency of OS X and have this option available when right-clicking (ctrl-clicking) a text field. Disabling autocorrection in Chrome, for example, is handled this way.

Other applications such as Firefox may require you hunting through the Preferences to disable the autocorrection feature.


iCloud Sync:

Automator and AppleScript Editor, both apps have been updated with iCloud compatibility. AppleScripts that you've created or Automator workflows can now be moved into the cloud and synced to all of your Macs that are running OS X Mavericks.

It's useful if you're creating and updating scripts or workflows that need to be deployed to a handful of Macs automatically.


Show Twitter feed in Safari's Sidebar

Update: It's not the complete feed, just messages with URLs embedded in them.

Being able to see your twitter feed in a Safari Sidebar is pretty cool, and definitely under documented.

  1. Add your Twitter credentials to the "Internet Accounts" panel of "System Preferences."
  2. Click on the "open book" icon in the new Safari bookmark bar.
  3. Select "Shared Links" or use the keyboard shortcut ^⌘3 to toggle "Shared Links".

I believe that this is all that I did to be able to see my twitter feed in the safari sidebar.


Messages now has a color setting called auto, which will color the messages of the person you're talking to in the way that they color their own messages.

  • This has existed for ages, right? I'm sure I used that back in Snow Leopard, and possibly before?… (At least with iChat)

  • Oh yup, you're right, I just checked my mountain lion machine. Maybe it just defaulted to that setting when I upgraded and I never noticed. So then it's just a cool under-documented feature of OSX hahah

This not exactly a useful feature, Java seems to be not installed by default and when you try to check java version in terminal, it takes you to the download page. Run this in terminal : java -version

enter image description here

as a feature, I find this quickest way to install Java :P

    This was also the case in Lion and Mountain Lion, I believe.

Hidden Dock won’t appear in fullscreen apps:

You may find that the Dock won’t show up from the bottom or right/left side (depending on where you put it) when apps are in fullscreen, and when you fast-move the cursor to where your Dock is hidden or when you pause right there and let the cursor hover. No Dock.

Here’s the trick:

You need to move the cursor very slowly. That’s all you need to do. If you move it too fast to the edge of your screen, the Dock won’t show up.


Side dock has new UI

It now looks like this (I really like the light that indicates which apps are open, it's a lot more clearer than the bottom dock):

enter image description here


Event reminders based on travel time

When you create an event in Calendar, you can specify a location. If the address is recognized, it'll insert a map right in the event details (and even give you the current weather conditions!).

But it goes even further. Calendar can also determine your current location, so you can tell it to calculate the travel time to the event based on where you currently are. If you do, that gives you a new alert option: "when I need to leave."

This is so much better than the old fixed-time options (1 hour before, 30 minutes before, etc.) because it's dynamic based on where you are and how far you need to drive.


Did someone noticed that the Remove from Dock option on the Trash icon's context menu in the Dock is gone. I clicked that a couple of times accidentally and then had to bring it back in Mountain Lion.


iBooks (for Mac) stinks (can't edit any metadata, kinda flakey about syncing with my iPad, you now have to interact with two programs to manage your books, etc.), but if you were unfortunate enough to have it suck all of your books out of iTunes and into its universe before you knew what was going on then here are a couple of tips.

To delete a book or PDF select the book and hit the Delete key. (There was something in iTunes that worked in that same non-intuitive way, wasn't there?)

To reduce the the flakiness of the sync I had to double-home-button-kill iBooks on my iPad, then try syncing again. It helped.

If out of habit you drag a PDF into iTunes it will be gladly accepted, but you won't be able to see it anymore, because the Books category is gone and there's no Library category anymore. It will show up as Music and you can delete it from there.

UPDATE: 9:30pm: NOW there's a "Delete" item showing up when you right-click on a book in the popup menu. That hasn't been there all day. Have no idea what made it start showing up. This program needs some work. It should have been iBooks beta.

    This might work better as a stand-alone question where you state the issues you have and how you have tried to solve them.
