A. Metal is supported with the following Mac models:
  • MacBook (Early 2015 or newer)

Specific third-party†† video cards that might support Metal:
  • AMD Radeon RX 560

  • AMD Radeon Pro WX 7100
  • AMD Radeon RX Vega 56
  • AMD Radeon RX Vega 64
  • AMD Radeon Pro WX 9100
  • AMD Radeon Frontier Edition
†† Third-party graphics cards vary, so you should check with the vendor of your specific graphics card for compatibility details - please check first before purchasing.
We at MacStrategy personally believe, and predict, that Apple will drop support for cheese-grater Mac Pros completely in macOS 10.16 or even as early as macOS 10.15 (due autumn/fall 2019), so you may want to watch spending large amounts of money to get a Metal supported video card for 10.14 Mojave, just to find Apple drops support for your actual Mac within 18 months!
Q. I've heard El Capitan includes something called System Integrity Protection (SIP). Will this stop me installing and using older software?
A. Possibly. See our separate article all about System Integrity Protection (SIP).
Q. I've heard El Capitan includes something called Gatekeeper. Will this stop me installing and using older software?
Install Os 10.11A. No. You can configure Gatekeeper in one of three different ways:
  1. Mac App Store = only software downloaded and installed from the Mac App Store will run (highest security)
  2. Mac App Store and identified developers = only software downloaded and installed from the Mac App Store or that have been digitally signed by an authorised developer will run (medium security - default)
  3. Anywhere = no security and will let you install any software
Q. Does El Capitan have Rosetta? Does it run PowerPC applications/software?
A. Just like OS X 10.7 Lion and later, El Capitan does not include Rosetta.
Q. Does El Capitan include X11?
A. No. X11 on El Capitan now uses install on demand. When you first launch an app that requires X11 libraries, you are directed to a download location for the most up-to-date version of X11 for Mac e.g. XQuartz.
Q. Does El Capitan include Personal Web Sharing?
A. Sort of. Apple have removed the easy configuration of this feature (from System Preferences > Sharing) but the underlying software needed (Apache) is still included in macOS. You can either purchase Apple's own OS X Server (£14.99), install/purchase third party products e.g. MAMP, or get jiggy with Terminal commands for free.
Q. Does El Capitan include Xgrid Sharing?
A. No. Just like OS X 10.8 Mountain Lion and later it has been removed.
Q. Does El Capitan include Java?
A. No. Java is available to download from Oracle - see our Java article for more information and download links to obtain the latest free Java software.
Q. If I install OS X 10.11 El Capitan and don't like it can I easily downgrade back to 10.10./10.9/10.8/10.7/10.6?
A. Unfortunately, depending on your Mac model it may not be very easy. We're working on an article about that - check back soon.
Q. What should I do to prepare for El Capitan?
A. See this article.

Jul 05, 2021 • Filed to: Solve Mac Problems • Proven solutions

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.

How to Update My Mac to OS X 10.11.6/10.11.4?

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.
