Mac users get new software updates and versions more frequently than the other operating systems. That's both the blessing and curse for the Mac users. The latest software makes your Mac device compatible with the new technological developments. Still, it also makes the existing OS obsolete. That's why most Mac users with old devices try to update their Mac to OS X El Capitan. However, you can't update your Mac to El Capitan 10.11 if your Mac runs on software later than Mac OS X 10.6 Snow Leopard.
Is OS X El Capitan Still Available for Your Mac?
OS X El Capitan (10.11) was launched on 25 September 2015, and it is an improved version of OS X Yosemite (10.10). Improved window management, quick and responsive interface, spotlight search, and enhanced graphics were the prerequisites of El Capitan OS. However, if you are planning to update your Mac to OS X El Capitan, your device must fulfill the following requirements.
Space Requirements
You can't install OS X El Capitan unless your Mac has a free space of 8.8 GB. However, that's the space you need to install El Capitan on your Mac. You might have to free more space to run your Mac more smoothly because low space slows down system performance.
Hardware Compatibility
Most of the Mac models can install and run OS X El Capitan, but in some devices, you can't use full features of this OS due to hardware limitations. For instance, you can't use AirDrop on your Mac if you don't have a WiFi network compatible with PAN. The followings are devices that are compatible with OS X El Capitan.
- MacBook introduced in 2009 or later, plus MacBook (13-inch, Aluminum, Late 2008)
- MacBook Air introduced in late 2008 or later
- MacBook Pro introduced in mid-2007 or later
- Mac mini introduced in early 2009 or later
- iMac introduced in mid-2007 or later
- Mac Pro introduced in early 2008 or later
- Xserve models introduced in early 2009
RAM Compatibility
RAM is the temporary memory that supports the system to run apps and programs efficiently. Without enough RAM, trust me, you can't even run your native operating system smoothly. Similarly, you can't install El Capitan unless you have 2 GB RAM on your Mac.
Operating System Compatibility
Operating systems play a critical role in creating an operational environment for both the software and the hardware. If you have decided to update your Mac PC, you have to make sure that your device doesn't run the OS later than Mac OS X Snow Leopard 10. 6. 8.

After you are done with checking the compatibility of your Mac device, it's time to follow some pre rituals to prepare your device for Mac OS X El Capitan 10.11. These steps are mandatory for the successful installation of El Capitan OS into your Mac, and Apple also suggests them.
Get Your Mac Ready for El Capitan Update
Unprepared installation of a new operating system can result in disappointment. Remember that you are going to get a relatively new OS for your older Mac. To increase the hardware compatibility of your Mac, you must go through a checklist for successful installation of OS X El Capitan.
Space in your Mac: This includes freeing space both on RAM and Disk drive. 2 GB RAM and 8.8 GB of disk space are mandatory because the installer would not proceed without the fulfillment of these hardware requirements.
Minimum battery requirement: During the OS update, a computer consumes battery quicker than the regular operations. Your Mac needs to have at least 45% battery to pass through the El Capitan installation.
Active Internet Connection: You can't proceed with any OS installation without an active internet connection. Along with the installation package, your Mac would also need some side installations throughout the update. Without the support of these plugins and drivers, you would be back to square one. So, an active connection is a must.
Update Apps: Outdated apps can halt the process of updating your Mac. As soon as the installation of Mac OS X El Capitan completes, you face a software crisis. Most of your apps would stop working, leaving you with a headache. That's why don't forget to update your apps before starting the update.
Backup Your Data: There's a high chance that you would lose your data during Mac OS X EI Capitan update because the new OS makes changes in every nook and corner of your PC. To prevent the possible data loss, make a double back up—one in the Time Machine and other in the external storage device. If there is any file missing after the El Capitan update, check how to recover files after OS X update.
Begin Update Process
Your device is ready to embrace Mac OS X El Capitan 10.11 after going through the steps mentioned earlier. Now it's time for some real action.
Step 1Visit the official Mac App Store and search for Mac OS X El Capitan. Your search result would Stake you to the El Capitan page. You can also download El Capitan without the App Store by the following links.
Step 2From the official El Capitan page, you can download your required version.
Step 3Once the download is done, the El Capitan installer will pop up on your screen.
Step 4Press the 'Continue' button and wait for the installation to begin. You can proceed with the installation by following the instructions of the installer.
Step 5The installation process does not take a long time. Once the installation is done, you can restore your data from Time Machine or external drive.
Recover Lost Files After OS X El Capitan Update
Do you remember those pre-installation steps? Those steps were taken to minimize the chances of data loss during the Mac OS X El Capitan installation. Despite these precautions, you are still at the risk of unprecedented data loss. You can lose data due to the following reasons.
Data loss due to corrupted files: If your Mac contains corrupted files, you will lose your data. During installation, the new OS tries to fix or delete corrupted files. These overwritten or deleted files would not appear after installation.
Nature of Mac OS X El Capitan's update: You will replace your older OS with a new version that is not tailor-made for your Mac. That's a significant shift in the environment of your Mac. Such kinds of major updates come with uncertainty, and you can't predict whether you are going to lose your data or not.
Hardware specifications: 2 GB RAM and 8.8 GB disk space is a standard requirement for El Capitan's update. But it takes a lot more from a Mac device to adapt to a newly enforced environment. A slight incompatibility can make you lose your data without any notice.

Wacom does not recommend upgrading to OS 10.11 (“El Capitan”) if using a Cintiq 27QHD or Cintiq 27QHD Touch until an updated driver is released. Wacom expects the driver to be available within one week of Apple’s release of OS 10.11
Wacom continually monitors the compatibility of our products with current operating systems. We have discovered that the Cintiq 27QHD (DTK2700) and the Cintiq 27QHD touch (DTH2700) will not function correctly on the upcoming Apple Mac OS (OS 10.11 El Capitan). Due to a change in the way Apple handles drivers that communicate with the Cintiq27 QHD scalar, an upgrade to OS 10.11 will cause you to lose the ability to use the Wacom Display Settings software to adjust brightness and contrast, or to adjust color profiles. You will also lose the ability to use the Wacom Color Manager software for color calibration of your Cintiq 27QHD.
When available the updated driver can be downloaded from this site.
We apologize for any inconvenience and appreciate your patience and support.
Note that this issue only affects the Cintiq 27QHD and Cintiq QHD Touch on Mac OS 10.11. Other Cintiqs not affected. Windows operating system is not affected.
Why does the Cintiq 27QHD or Cintiq 27 QHD Touch Not Work with Mac OS 10.11 (El Capitan)?
The Cintiq 27QHD and Cintiq 27QHD Touch uses a sophisticated scalar for color management and other display settings. A special chip is used to communicate with the scalar which requires a driver. Apple’s OS contains a native driver but this does not have all the functions required to communicate with the scalar. As a result, the chip manufacturer provides a custom driver that replaces the stock Apple driver. With the release of Mac OS 10.11 Apple now prevents replacing the stock, driver and therefore communication to the scalar does not function.
Why do other Cintiqs not have this problem?
Only the Cintiq 27QHD and Cintiq 27QHD have the sophisticated scalar for advanced hardware color management.
What are the symptoms?
If you upgrade or install the Mac OS 10.11 the following will occur:
El Capitan Installer Usb
- When trying to use Wacom Display Settings to adjust brightness, contrast or color options, a warning will appear asking you to restart your computer in order to load a driver. A reboot will not load the driver.
- When trying to use Wacom Color Manager to color calibrate your Cintiq 27QHD, the software will be unable to establish connection with your display. Pressing “Retry” will not establish the connection.
What workarounds exist for this issue?
There are no simple workarounds at this time.
Advanced users may consider the following. The Cintiq 27QHD and Cintiq 27QHD Touch maintain their settings in hardware, enabling you to change settings in one environment but use the Cintiq in another.
El Capitan Installer Apple
Since the communication issue is not present in older Mac OS versions, you might load Mac OS 10.11 into a separate partition and keep the older partition for running color calibration and/or changing display settings. Since these functions are only done periodically your ability to work in Mac OS 10.11 would be preserved.
El Capitan Installer Boot Usb
A further option would be to change settings on the Cintiq using a Windows OS computer then to re-attach the computer to the Mac running OS 10.11 Neither of these options are ideal but they would work in an emergency to allow adjustments to the Cintiq’s display settings.
