1. Hiding the menu bar
If you've been using Mac OS X software for a while, you no doubt know that you can hide the dock so that it doesn't get in your way until you need it. New to El Capitan is the option to hide the menu bar in much the same way: it disappears from view until you move the mouse cursor to the top of the screen. If you want as much space as possible for your applications and windows, you can find the setting on the General page of System Preferences.
2. Split the view
Like iOS 9, El Capitan includes a new Split View mode that lets you click & # 39; windows & # 39; & # 39; – you can quickly get a spreadsheet in addition to a web page for example (and yes, it looks a lot like the snapping function that Windows has had for a while). To pin a window, hold down the green zoom button and drag it to the left or right; you will then be asked to choose another window to fill the other side. Drag the central border to change the position.
3. Find the mouse cursor easier
You may see this as a small upgrade, but many people will find it very useful – if you lose sight of the mouse cursor, move around your mouse or move your fingers quickly over the trackpad and the cursor becomes larger so that you can find it again. Remember that Apple nowadays produces 5K screens, so tracking the cursor is not as easy as before. Go to System Preferences in the Apple menu to find more options for mouse and trackpad.
4. Skip the trash
Another feature that Windows users have had for years is the option to immediately delete files without temporarily staying in the Recycle Bin (useful for sensitive files that you absolutely don't want to be) restored). With El Capitan you can also do this in the Apple operating system: press Option + Cmd + Delete while the relevant files are selected or hold down the Option key, open the File menu and choose Delete Immediately. However, make sure you have marked the correct files first, because they are almost impossible to come back.
5. Keep an eye on your friends
Find My Friends is now a native app in iOS 9 and an official widget has been added to El Capitan. If you open the Notification Center on the right side of the OS X display and go to the Today tab, you will see an Edit button that you can use to add the widget. You can use it to keep track of friends, family members and just about anyone who has agreed to share their location with you from their iOS device: click on one of the listed profiles to view a map tile.
6. Customize the Notification Center layout
The Notification Center is your hub for managing every important notification and update coming in from your apps, so any way to customize it should be a welcome one. El Capitan adds the option to group your notifications by date (the new method) or by app (the old method used in Yosemite). You can switch between the two modes by going to System Preferences, opening the Notifications screen and then clicking the drop-down menu at the bottom right of the window. As before, individual app notifications can also be adjusted here.
7. Renaming files from the context menu
Another small but potentially important modification in El Capitan (depending on how you use it) is the ability to rename files from the context menu in Finder instead of pressing Enter. tap to enter a new file name: Ctrl + click on a file to go to the menu where Rename is located. It is not clear why it took Apple's development team so long to add this alternative method, but perhaps they were thinking about making life easier for anyone who switched from Windows, where a right-click is often the most intuitive one way is to rename a file.  8. Follow flights with a click
El Capitan contains a number of new functions based on the concept of automatic scanning and recognition of text in your documents and messages. One of these new features is the ability to track flights if a real flight number is spotted: if you see a highlighted box around a flight number in Notes or in Mail, you can click it to get details about where the plane is going and when it is planned to get there. Now there is even less of an excuse for not being at the airport when you need to be.
9. Perform natural searches
OS X & # 39; s comprehensive search tool Spotlight gets an upgrade in El Capitan, an upgrade that allows you to find files and information in natural language. If you want to get an idea of what we mean, search for & # 39; photos & # 39; s from last June & # 39; or & # 39; spreadsheets about money & # 39; to see what appears. You can also request weather, sports and stock information from the web and find YouTube and Vimeo videos & # 39; s alongside all the usual Spotlight tricks via the interface. To top it all off, you can now move the Spotlight panel across the screen – innovation indeed.
10. Make richer Notes
As always, the most important apps from Apple get an upgrade and OS X at the same time, and Notes get a wealth of new features to play with. For example, Notes can now include drawings, checklists, video files, and map locations, and it seems that Apple now seriously wants to record Evernote (remember that Notes also has a similar upgrade in iOS 9). After you upgrade your computer to El Capitan, Notes is also displayed on the Share menu when you call it from other apps.
11. Check the directions of public transportation in Maps
As with iOS 9, the major upgrade as far as Apple Maps is concerned is support for public transportation information, so you can plan a route from A to B with buses, trains and trams. Unfortunately, it is currently supported only in a handful of major cities in the world, including London in the UK and New York and San Francisco in the US. If it's available in your region, click the new Transit button at the top of the Directions pane on the left to view your options and click through for more information.
12. Editing photo metadata
Metadata is the semi-hidden information that is stored alongside your mobile photos when they are taken: for example, the date and time of the photo, and usually the GPS location wherever you were. El Capitan gives you the option to edit this metadata if needed (many photo management tools use it to keep your photos in order) – click the info button from the Photos & # 39; s app (a & # 39; i & # 39; in a circle) then double-click the date and time to make changes. You can also drag the red thumbtack around to edit the corresponding location.
13. Installing photo extensions
With El Capitan you can install third-party photo applications as extensions in the main photo app. This basically means that you can access their editing tools and other options from within Photos without ever having to switch apps. To start, you must install a compatible app that supports photo extensions (such as Macphun & # 39; s Tonality or BeFunky Express) and then go to the Extensions panel of System Preferences to enable it. Open an image in Photos, click on Edit and then on Extensions to find your newly installed app and the available functions.
14. Use gestures in Mail
The Mail app bundled with El Capitan offers new support for gestures that allow you to navigate through your inbox faster than ever. With a two-finger swipe on the trackpad, you can mark messages as read or unread (go to the right) or discard them (go to the left). Another useful new feature that is worth mentioning is the ability to minimize draft emails with a click of the yellow button – that means you can finally go back to your inbox in the Mail app without the email. mail you are preparing to leave.  15. Add events and contacts from emails
The Mail app from El Capitan is smarter than the one in Yosemite: it can recognize names and events in your messages and add them automatically if necessary to your Contacts or Calendar apps. You do not need to do anything to enable this function, just click on the Add button at the top of emails or open the pop-up menu next to the relevant info; if you don't want to add it to your other apps, just ignore it. The usefulness of this feature ultimately depends on how intelligent Mail can scan your messages for data.
16. Transfer online video & # 39; s to an Apple TV
A small but important new feature in El Capitan, if you are going to use something: the ability to transfer a specific online video via AirPlay Stream Apple TV instead of having to stream the entire browser window. If you start Safari and open a compatible video page (a YouTube clip works fine), you should see an AirPlay button on the playback toolbar. Click on it and then choose your Apple TV from the list. Quicktime video & # 39; s also work, but you must use Safari as your browser application.
17. Pin tabs in Safari
If you have used a different browser in addition to Safari on your Mac, you know how pinned tabs work, but El Capitan updates Apple's own browser to offer the same function . Click and hold a tab in Safari and drag it to the left to pin it – pinned tabs will stay in place on the left side of the screen even after you close the browser and restart. They are useful for windows to which you must refer a lot, such as your e-mail client or a Twitter feed. Drag a tab to the right to release it.
18. Muting tabs in Safari
Few browsing experiences are more frustrating than letting audio from an unknown tab somewhere in your open windows, but the El Capitan version of Safari relieves the pain somewhat through a small speaker. places icon on the tab that is to blame. In addition, you can click once on this icon to mute the tab so that you can continue browsing without further interruption. You will also see a speaker icon in the address bar: you can click it to mute the current tab (if audio is playing) or to mute all background tabs (if not).
19. Adjust the Reader View of Safari
Did you know that the Apple web browser had a Reader View that cuts the ads and other derivations of a page so that you can focus on the text? The feature – which is accessible by clicking on the icon with the horizontal lines to the left of the address bar – is not new in El Capitan, but new is the way you can adjust this view to your taste: click the An icon to the right of the address bar in Reader View to change fonts, colors and text size as desired.
20. Switch between window formats with a double click on
Another of the small but useful functions of El Capitan is double clicking on the title bar of the window. In earlier versions of the operating system, this would cause the window to the Dock to be kept to a minimum, but in El Capitan it switches between a larger and smaller window size. To change which setting the software uses, open System Preferences and click on the Dock icon: in the next screen, open the drop-down menu next to Double-click on the title of a window and make your choice. The two window sizes can be set manually by dragging the edges of the window as normal.
21. Enjoy faster gaming performance
With the arrival of Mac OS X El Capitan, OS X gets the same Metal technology available in iOS 9 – it gives game developers the option to write low-level code which gives access to the graphics chip directly, which reduces unnecessary bloat and (in theory) gives you a faster, smoother gaming experience. This is not a tip that you can actually put action on or on and off, but it is something else to look forward to while using third-party software on Apple's latest desktop operating system, especially visually intensive apps.
