A gentle introduction to Mac OS X. A manual for beginners with some todo tasks at the end. I've done it for a school presentation while in Erasmus at Poland (Technical University of Lodz), and I hope you find it useful:). OS X El Capitan: The smart person's guide. Apple will issue periodic updates to OS X El Capitan through the Mac App Store. It includes several user and enterprise features, and it improves. To automatically install macOS updates in the future, including apps downloaded from the App Store, select âAutomatically keep my Mac up to dateâ from Software Update in System Preferences. I am a seasoned Mac user, but Gary never ceases to amaze me with great little tidbits to make life easier. This is an excellent course for any Mac user, nicely paced, and comprehensive even for someone who is brand new to the OS. I liked that I could airplay it to my apple tv and try the features of El Capitan out by following along.
OS X El Capitan supports two methods of installation. The default method is an upgrade install, which will upgrade your Mac to El Capitan while preserving all of your user data and apps. This is the most common means of upgrading the operating system and is recommended when your Mac is in good shape and having no problems.
The other installation process is known as the clean install. It replaces the contents of a selected volume with a new, pristine version of OS X El Capitan that does not include any previous versions of the operating system, applications, or data files that may have been present on the selected drive. The clean install method is a good choice for testing a new OS on a dedicated drive or partition, or when you have been experiencing software related issues with your Mac that you have not been able to fix. When the problems are severe enough you may be willing to trade keeping all of your apps and data for starting with a clean slate.
It's the second option, a clean install of OS X El Capitan, which we'll address in this guide.
What You Need Before Installing OS X El Capitan
Before proceeding, you should first verify that your Mac is capable of running OS X El Capitan; you can do this by visiting:
Once you've checked out the requirements, come back here for the next, extremely essential, step:
Back Up Your Existing Version of OS X and Your User Data
If you're going to install OS X El Capitan on your current startup drive using the clean install method, then you will by definition erase everything on the startup drive as part of the process. Thatâs everything: OS X, your user data, anything and everything you have on the startup drive will be gone.
No matter why you're undertaking a clean install, you should have a current backup of the existing startup drive's contents. You can use Time Machine to perform this backup, or one of the many cloning apps, such as Carbon Copy Cloner, SuperDuper, or Mac Backup Guru; you can even use Disk Utility. The choice is up to you, but whatever you choose, it's important to take the time to create a current backup before you start the installation.
Types of Clean Installs
There are actually two types of clean installs you can perform.
Clean Install on Empty Volume: The first option is the easiest: installing OS X El Capitan onto an empty volume, or at least one whose contents you donât mind removing. The key point is that you're not targeting your current startup volume as the destination for the clean install.
This type of clean installation is easy because, since the startup drive isn't involved, you can perform the clean install while booted from the current startup drive. No special, custom-made startup environment needed; just start up the installer and go.
Clean Install on Startup Volume: The second option, and perhaps the more common of the two, is to perform a clean install on the current startup drive. Because the clean install process erases the contents of the destination drive, it's obvious that you can't boot from the startup drive and then try to erase it. The result, if it were possible, would be a crashed Mac.
Thatâs why if you choose to clean install OS X El Capitan on your startup drive, there's an extra set of steps involved: creating a bootable USB flash drive that contains the OS X El Capitan installer, erasing the startup drive, and then starting the clean install process.
Check the Target Drive for Errors
Before you start any installation process, it is a good idea to check the target drive for problems. Disk Utility can verify a disk, as well as perform minor repairs if a problem is found. Using Disk Utilities First Aid feature is a good idea before you start the install process.
Perform the steps outlined above, when completed return here to begin the installation process.
Let's Get Started
If you haven't yet downloaded a copy of OS X El Capitan from the Mac App Store, you'll find instructions for how to do this in our article: How to Upgrade Install OS X El Capitan on Your Mac. Once the download completes, come on back here to continue the clean install process.
If you decided to perform the clean install on an empty volume (not your startup drive), you can jump ahead to Step 3 of this guide.
If youâre going to perform the clean install on your Mac's current startup drive, continue on to Step 2.
Erase Your Mac's Startup Drive Before Installing OS X El Capitan
To perform a clean install of OS X El Capitan on your Mac's current startup drive, you'll first need to create a bootable version of the OS X El Capitan installer. You can find instructions in the guide:
Once you finish making the bootable USB flash drive, we're ready to continue.
Booting From the OS X El Capitan Installer
The following process will erase all of the data on your startup drive. This can include all your user data, music, movies, and pictures, as well as the current version of OS X installed. Make sure you have a current backup before proceeding.
You will be returned to the OS X Utilities window.
Start the OS X El Capitan Installation Process
With the startup volume erased, you're now ready to begin the installation of OS X El Capitan.
Launch the El Capitan Installer to Perform a Clean Install
At this point in the clean install of OS X El Capitan, the two supported methods of performing a clean install are about to merge. If you chose to perform a clean install on your current startup drive, as defined in the beginning of this guide, you then performed all of the tasks on Step 1 and have erased your startup drive and started up the installer.
If you chose to perform a clean install on a new or empty volume (not your startup drive) as described earlier in the guide, then you're ready to start the installer, which you'll find in the /Applications folder. The file is labeled Install OS X El Capitan.
With that step performed, we have unified the two installation processes; going forward, all steps are the same for both clean install methods.

OS X El Capitan Setup Includes Creating Your Administrator Account
When the installation process is complete, your Mac will reboot, and the OS X El Capitan setup assistant will automatically start. The assistant will help you through the process of configuring your Mac and OS X El Capitan for use.
If you remember when you first got your Mac, you went through a similar process. Because you used the clean install process, your Mac, or at least the drive on which you chose to clean install OS X El Capitan, now looks and acts just like the day you first turned it on.
OS X El Capitan Setup Process
The setup process is complete. After a few moments, you'll see the OS X El Capitan desktop, which means you're ready to start exploring the clean installation of your new OS.
OS X El Capitan (/ÉlËkæpɪËtÉËn/el-KAP-i-TAHN) (version 10.11) is the twelfth major release of OS X (now named macOS), Apple Inc.'s desktop and server operating system for Macintosh computers. It is the successor to OS X Yosemite and focuses mainly on performance, stability and security.[3] Following the Northern California landmark-based naming scheme introduced with OS X Mavericks, El Capitan was named after a rock formation in Yosemite National Park, signifying its goal to be a refined version of Yosemite.[citation needed] El Capitan is the final version to be released under the name OS X; its successor, Sierra, was announced as macOS Sierra. El Capitan received far superior reviews when compared to Yosemite.
The first beta of OS X El Capitan was released to developers shortly following the WWDC keynote on June 8, 2015.[4] The first public beta was made available on July 9, 2015.[5] There were multiple betas released after the keynote. OS X El Capitan was released to end users on September 30, 2015, as a free upgrade through the Mac App Store.[6]
System requirements[edit]
All Macintosh computers that can run Mountain Lion, Mavericks, or Yosemite can run El Capitan,[7] although not all of its features will work on older computers.[8] For example, Apple notes that the newly available Metal API is available on 'all Macs since 2012'.[9]
These computers can run El Capitan, provided they have at least 2GB of RAM:[10]
Of these computers, the following models were equipped with 1GB RAM as the standard option on the base model when they were shipped originally. They can only run OS X El Capitan if they have at least 2GB of RAM.
The following computers support features such as Handoff, Instant Hotspot, AirDrop between Mac computers and iOS devices, as well as the new Metal API:[11]

The upgrade varies in size depending upon which Apple Mac computer it is being installed on, in most scenarios it will require about 6 GB of disk space.[12]
Features[edit]
OS X El Capitan includes features to improve the security, performance, design and usability of OS X. Compared to OS X Yosemite, Apple says that opening PDFs is four times faster, app switching and viewing messages in Mail is twice as fast and launching apps is 40% faster.[13][14] The maximum amount of memory that could be allocated to the graphics processor has been increased from 1024 MB to 1536 MB on Macs with an Intel HD 4000GPU.[15] OS X El Capitan supports Metal, Apple's graphics API introduced in iOS 8 to speed up performance in games and professional applications.[16] Apple's typeface San Francisco replaces Helvetica Neue as the system typeface.[17] OS X El Capitan also adopts LibreSSL in replacement of OpenSSL used in previous versions.[18]
Window management[edit]
An example of the split screen view in OS X El Capitan
OS X El Capitan introduces new window management features such as creating a full-screen split screen limited to two app windows side-by-side in full screen[19] by pressing the green button on left upper corner of the window or Control+Cmd+F keyboard shortcut, then snapping any supported other window to that full screen application. This feature is slightly similar to, although less extensive than, the snap-assist feature in Windows 7 (and later) and several Linuxdesktop environments, such as GNOME.[20] OS X El Capitan improves Mission Control to incorporate this feature across multiple spaces. It also enables users to spot the pointer more easily by enlarging it by shaking the mouse or swiping a finger back and forth on the trackpad.[21]
Applications[edit]Messages and Mail[edit]
OS X El Capitan adds multi-touch gestures to applications like Mail and Messages that allow a user to delete or mark emails or conversations by swiping a finger on a multi-touch device, such as a trackpad. OS X also analyzes the contents of individual emails in Mail and uses the gathered information in other applications, such as Calendar. For example, an invitation in Mail can automatically be added as a Calendar event.
Maps[edit]
Apple Maps in El Capitan shows public transit information similar to Maps in iOS 9.[13] This feature was limited to a handful of cities upon launch: Baltimore, Berlin, Chicago, London, Los Angeles, Mexico City, New York City, Paris, Philadelphia, San Francisco, Shanghai, Toronto and Washington D.C.
Notes[edit]
The Notes application receives an overhaul, similar to Notes in iOS 9. Both applications have more powerful text-processing capabilities, such as to-do lists (like in the Reminders application), inline webpage previews, photos and videos, digital sketches, map locations and other documents and media types. Notes replaces traditional IMAP-based syncing with iCloud, which offers better end-to-end encryption and faster syncing.[22]
Safari[edit]
Safari in El Capitan lets users pin tabs for frequently accessed websites to the tab bar, similar to Firefox and Google Chrome. Users are able to quickly identify and mute tabs that play audio without having to search for individual tabs. Power mac 320 chainsaw manual. Safari supports AirPlay video streaming to an Apple TV without the need to broadcast the entire webpage. Safari extensions are now hosted and signed by Apple as part of the updated Apple Developer program and they received native support for content blocking, allowing developers to block website components (such as advertisements) without JavaScript injection.[23] The app also allows the user to customize the font and background of the Reader mode.[24]
Spotlight[edit]
Spotlight is improved with more contextual information such as the weather, stocks, news and sports scores. It is also able to process queries in natural language. For example, users can type 'Show me pictures that I took in Yosemite National Park in July 2014' and Spotlight will use that request to bring up the corresponding info.[25] The app can now be resized and moved across the screen.[26]
Photos[edit]
Photos introduced editing extensions which allows Photos to use editing tools from other apps.[27]
System Integrity Protection[edit]
OS X El Capitan has a new security feature called System Integrity Protection (SIP,[28] sometimes referred to as 'rootless'[29][30]) that protects certain system processes, files and folders from being modified or tampered with by other processes even when executed by the root user or by a user with root privileges (sudo). Apple says that the root user can be a significant risk factor to the system's security, especially on systems with a single user account on which that user is also the administrator. System Integrity Protection is enabled by default, but can be disabled.[31][32]

Reception[edit]
Upon release, OS X El Capitan was met with positive reception from both users and critics, with praise mostly going towards the overall functionality of the new features and improved stability. Dieter Bohn of The Verge awarded the operating system a score of 8.5 out of 10;[33] while Jason Snell of Macworld was also positive, rating it 4.5 out of 5.[34]
Issues[edit]
After the 10.11.4 update, many users started reporting that their MacBooks were freezing, requiring a hard reboot.[35] This issue mostly affects Early 2015 MacBook Pro computers, although many others have reported freezes in other models.[36] Several users created videos on YouTube which showed the freezes.[37][38][39] Soon after this, Apple released the 10.11.5 update, which contained stability improvements. Ge mac 1200 operator's manual. Apple later acknowledged these problems, recommending their users to update to the last point release.[40]
After the December 13, 2016 release of Security Update 2016-003, users reported problems with the WindowServer process becoming unresponsive, causing the GUI to freeze and sometimes necessitating a hard reboot to fix.[41] In response, on January 17, 2017, Apple released Security Update 2016-003 Supplemental (10.11.6) to fix 'a kernel issue that may cause your Mac to occasionally become unresponsive' and at the same time released an updated version of Security Update 2016-003 which includes the fix released in the supplemental.[42] Users who have not previously installed Security Update 2016-003 are advised to install the updated version to reach build 15G1217, while users who have already installed the December 13, 2016 Security Update 2016-003 only need to install the supplemental update.
