Ever end up with a lot of Finder windows floating around your Mac screen? In previous versions of Mac OS X, the choice was to close them all with a keyboard shortcut, Option-Command-W, which will end all your Finder suffering in one short tap.

In Mavericks beta, that still works. Yet Apple has also added another way to deal with multiple Finder windows: merging them. Here’s how.

We’re still finding some great new features and tricks in OS X Mavericks beta, and while it’s not a huge overhaul like the more populare iOS 7 update, Mavericks has plenty of great things going on under the hood. And some of it even on top of the hood.

Here are five more interesting tips and tricks about the latest iteration of Apple’s Mac operating system, OS X Mavericks beta.

Are you a registered developer with Apple? Do you want to try out Mavericks without risking your entire Mac to a potentially wonky version of OS X? I haven’t seen any major issues, yet, but that doesn’t mean that mission critical softaware you rely on will work in Mavericks beta.

So, here’s the solution. Boot up from a USB stick that has been configured as a bootable OS X Mavericks drive. Here’s how.

OS X Mavericks beta, while not quite an overhaul as iOS 7, still carries quite a few new enhancements and features that you might not necessarily see at first glance. There are plenty of hidden features, which we’ve already detailed here on Cult of Mac, but more continue to be found. Lucky you, we’re here to help put them all together in one place.

Here are five of those hidden features for OS X Mavericks beta, each perhaps surprising in their own, special way.

AutoFill has been a part of OS X and Apple’s browser, Safari, for a while now. When you fill out forms on the web, Safari will prompt you to use your contact info to fill in the form, or to use the form data you entered as your AutoFill information. This is helpful as you fill out a lot of web forms, of course.

Now, in OS X Mavericks beta, Safari has a new trick up its sleeve, with the ability to suggest secure passwords to you, and then saving them for you when you go back to that site. It’s called iCloud Keychain, and here’s how to set it up.

Calendar, previously iCal, has had Time Zone support for a while now. The Mac I’m using that runs OS X Mountain Lion let’s my turn on Time Zone Support in the Advanced tab of the Calendar preferences, so I can be sure to be on time for meetings when I travel away from my current timezone (AKDT).

However, when using Time Zone support in Mountain Lion, calendar events that I scheduled in one time zone wouldn’t ever show me visually that they were. OS X Mavericks takes care of this problem with a small visual cue–now events scheduled in one time zone will show that time zone in their title in Calendar. Here’s how to make that happen.

When you’re galavanting about with your MacBook Air or Pro, it’s important to manage you battery power. It just wouldn’t do to show up for an important meeting or interview with a dead battery, let alone not being able to watch a movie on the airplane, now would it?

Knowing which apps are sucking up the most juice is key to this effort, of course, and OS Mavericks beta makes it severely easy to know which ones are the most power-hungry. That way, you can quit the apps that are using up too much battery in order to leave enough power for the important stuff.

Here’s how it works.

One of the lesser talked-about features of the upcoming OS X Mavericks system is that of Mac App Store subscriptions. In iOS, developers are able to charge users on a recurring basis, like a subscription. Magazines in Newsstand do this fairly easily, and I have several subscriptions to magazines there.

This wasn’t available to OS X apps until the release of OS X Mavericks, and you can manage your subscriptions from the Mac App Store right now if you’re running the new Mavericks beta on your Mac right now. Here’s how.

In the OS X Calendar, at least up to OS X Mountain Lion, the way to move from month to month, or week to week, is to hit the right or left arrows near the top of the calendar window, a fairly typical mechanic among calendar apps, really.

In OS X Mavericks beta, however, you can move through them much more intuitively. Here’s how.

One of the features I’ve been most looking forward to in OS X Mavericks is the ability to send directions from my Mac to my iPhone, to be able to take my directions on the go, even when I’m searching on my Mac. I hate having to go to my iPhone (or iPad) and re-enter the starting and ending addresses again; I just did that on my Mac!

While you still can’t do that with Google directions, you can now send directions from OS X Mavericks Maps right to your iOS Maps. Here’s how.
