1.6GHz or faster processor with SSE2 support; 64-bit versions of Microsoft Windows 10 (recommended with version 1607 or later), Windows 8.1, or Windows 7 with Service Pack 1.
Adobe has discovered the compatibility issues listed below with running Lightroom CC 2015 or Lightroom 6 with Mac OS 10.11 (El Capitan).
We recommend that customers do their own testing on a nonproduction partition to ensure that new operating systems work with their current hardware and drivers.
If you do encounter issues not already documented, feel free to report them on our feedback site.
Tethering Nikon cameras is supported in El Capitan as of Lightroom CC 2015.4 and Lightroom 6.4.
Direct tethering of most Leica cameras using Lightroom CC 2015 and Lightroom 6 is not currently supported on El Capitan.
Tethering Leica S (Typ 007) cameras is supported on El Capitan through the 'Leica Tethered Plug-in' which can be downloaded from the Leica Owners' Area.
Adobe recommends that customers who rely on Lightroom for tethering Leica cameras, other than the Leica S (Typ 007), do not upgrade to El Capitan at this time.
Update Mac OS X (El Capitan) to version 10.11.4 correct this issue.
If Lightroom is put in native Mac OS X full screen mode, there are some inconsistent behaviors:
To exit native full screen mode, move the cursor near the top of the screen so the application bar with minimize/maxize buttons are visible. Click the green button (the button on the right of the three buttons) to exit native full screen mode
If you cmd + tab away from Lightroom to another app and come back to Lightroom using cmd + tab while a dialog is open in native full screen mode, the main Lightroom app window is active instead of the dialog. To access the dialog window, use the 3-finger gesture to swipe up and select the space/window with the dialog you want to access to commit or cancel it.

I have installed El Capitan 10.11.6 on three computers. The install was tedious but not difficult. Most of the new features were things I didn't want.
El Capitan was replaced by macOS Sierra in September 2016. The latest version of Mac OS X is version 10.15, 'Catalina', released in 07 Oct 2019.
Graham Needham's MacStrategy Article on El Capitan describes many of the user interface changes.
El Capitan has user interface refinements and a new system font, San Francisco. There are also application improvements to Mail, Notes, Safari, Maps, Disk Utility, Photos, Spotlight, and Maps. There is more emphasis on full-screen mode and on iOS integration.
Apple says El Capitan contains performance improvements over Yosemite and earlier versions. My computer does seem a little faster.
Tighter security protections are included: 'rootless' System Integrity Protection protects the core OS from changes by malware or mistakes. Also, Apple fixed 101 security bugs, and subsequent updates fixed even more.
For more info, see this Apple page. Ars Technica has posted a long review.
I installed El Capitan 10.11.5 on two computers, and encountered only two programs that broke as a result: Adobe Illustrator CS5 and Photoshop CS5.
Apple software: Some Mail.app users reported corrupted data, corrupted or missing accounts, failing connections, reappearance of deleted messages, and crashes. If you use IMAP accounts in Mail, you may be able to get them working by deleting and re-creating them. (Don't do this for POP accounts; it will delete all the mail. Many people report trouble with POP accounts.) My POP and Gmail IMAP accounts worked fine after upgrading. Not all mail servers implement mail protocols the same way, though, and some of the problems people report sound to me like the result of using a mail server that does operations in ways that Apple's mail client does not expect.
Third party apps:Microsoft Outlook 2011 requires a patch from Microsoft, available 2015-10-07 as 'Office for Mac 2011 14.5.6,' to cure an application hang. Some people report that it doesn't keep Outlook from crashing immediately. Microsoft Office 2016 is also encountering multiple issues. Users report that they cannot install Microsoft Office 2008 or Microsoft Office 2011 (out of date) on El Capitan. If Office was already installed on Yosemite and you upgrade to El Capitan, it will work. Adobe Illustrator CS5 has problems. See 'Bugs/Gotchas' below. Adobe Photoshop CS5 has problems with type. See 'Bugs/Gotchas' below.
Hardware support: Some printer brands do not have updated drivers for 10.11, and some fail to print. USB audio with asynchronous clocks was not working until 10.11.4. Time Machine automatic backups are not starting if a UPS control panel is connected via USB.
Security: Updating to El Capitan will remove non-Apple files from the core system, and prevent modification of the core system. These changes may break some third-party software that attempts to modify the core system.
Not everyone can use the new OS version.
When you decide to install El Capitan, do it carefully. You may find that there are issues that affect you: do your homework. Check MacInTouch to see if there are problems with OS X 10.11 that affect you.
Make sure you back up your entire disk before starting to install El Capitan.
Make a list of the hardware you depend on, and search the web to check that each device will work. Older printers and scanners can have issues.
Best calendar app for mac blotter. Leave yourself enough time. Upgrading will tie up your computer for a big part of a day. Installing takes an hour or two, but then your computer will be very slow until it re-does the Spotlight index and backs up to Time Machine.
PowerPC-only programs on your computer will not run on El Capitan. (System Profiler no longer lists the 'Kind' of program in its Applications report.) To list these programs, open a Terminal window and type
Many of these programs are not problems: they are leftovers from old software installers or previous versions of software. For example /Library/Application Support/Adobe/AdobePDF.app. If you have questions, contact the manufacturer.
Here is a partial list of minimum program versions needed for El Capitan. For other programs, check product websites, or RoaringApps.

|Apple OS X Server||5.0.4||$19.99, free upgrade for Yosemite|
I installed El Capitan 10.11.5 on two computers in May-June 2016. It took most of a day for each machine, not including testing each feature.
Once you are satisfied that your computer works acceptably, and you are going to stay on El Capitan, you can make some adjustments.
You will probably want to set up per-user customizations, such as your desktop background and screensaver. After each new OS generation this is something of an adventure; functions get renamed and moved around. Most of my customizations from Yosemite were still there on El Capitan. but you have to check.
A big feature of El Capitan is System Integrity Protection (SIP). It prevents any user, even root, from modifying certain files and directories. This is good. Unfortunately some applications can't be installed while SIP is enabled.
Under El Capitan, Spotlight 'shows suggestions from the Internet, iTunes, App Store, movie showtimes, locations nearby, and more.' To do this, it sends your location and query to Apple servers. You may wish to change this if you are required to keep some information private. Change it in two places: uncheck 'allow Spotlight Suggestions' in ► System Preferences.. ► Spotlight ► Search Results and uncheck 'Safari & Spotlight Suggestions' in ► System Preferences.. ► Security&Privacy ► Privacy ► Location Services ► Privacy ► System Services ► Details.
While I was installing programming tools, I disabled System Integrity Protection (SIP). To do this, shut down your computer and restart it holding down Command and P. Then choose Utilities ► Terminal to open a Terminal window, and type csrutil disable to turn off SIP. Then type reboot to restart OSX. After all installations are done, re-enable SIP.
After all installations are done, re-enable SIP by booting into the recovery environment and typing csrutil enable .
There is a new preference in ► System Preferences.. ► General called 'Allow Handoff between this Mac and your iCloud devices'. It lets you start writing an email on the Mac and then finish it on an iPhone, or look at something in Maps on the phone and explore more on the Mac. It works over Bluetooth. For more info, see 'OS X El Capitan: Features enabled when your Mac and devices are nearby'. This sounds like a recipe for confusion, interference, and non-intuitive behavior. I turned it off.
I noticed that my Mac knew about a lot of WiFi networks that it had never connected to. They were listed in ► System Preferences.. ► Network ► WiFi ► Advanced. These networks were ones that my iPhone had connected to at some time in the past. years ago, in some cases. I guess this was a result of 'iCloud Keychain.' After installing El Capitan, My Mac connected to one of these networks rather than my preferred home network, and it made things very slow. I deleted the unwanted networks, a tedious process.
Photos has reorganized its content to be more like the iPhone. It is now possible to use third-party extensions to Photos; a few are available in the App Store. I am interested in Pixelmator and Polarr.
Dashboard is now off by default: I rarely used it. The setting for this is in Mission Control, which has many new features. If you use multiple monitors, check the 'Displays have separate spaces' switch in Mission Control to see if it does what you want.
Calendar now searches your mail for appointments by default. You can turn this off.
Spotlight will search in a lot of new places, unless you turn off these features.
Burning a CD-ROM from the Finder works differently. Insert a blank disc, put the data you want in a folder, right-click, and select 'Burn to disc.' Nothing will appear to happen for a long time, possibly several MINUTES, especially if you are trying to burn a large folder. Then a popup will appear asking you to insert a blank disc, and then another asking for the disc title, and then a progress popup.
Split View is a way to split the screen between two apps. I tried it out. Maybe I will think of a use for it someday.
Mail worked fine for me. I did not observe a long archive conversion process; my old mail appears to be present; I can send and retrieve messages. The Activity window is now always in front of all other windows.
Third party apps that appear to work OK: Firefox, Photoshop CS5, Office 2011, Quicken (Lion), Cisco VPN, Cloak.
OSX Install was slow on a non-SSD machine and appeared to be hung at '31 minutes remaining' for a long time. I waited, and it finally finished. On an SSD machine it was pretty quick.
I upgraded a late 2013 Macbook Pro to El Capitan from Yosemite, But my venerable wired USB Logitech mouse did not work right. When I tried to select text, the highlight region would select by words instead of characters, or after I finished selecting and released the mouse, the selection region would vanish. I would try to single-click the title bar of a window to bring it to the front, and the window would minimize as if double clicked. It was very difficult to do simple selections in Photoshop, or cut and paste text.
I searched the web, and some people were having trouble with wireless mice, while others seemed to have problems similar to mine, but there was no clear match. I tried a USB mouse that came with an Acer computer. It had the same problems. (Its manufacturer ID says 'Lite-on.') Then I tried a Kensington 'Mouse-in-a-Box' wired USB mouse. Everything worked fine.
There seems to be some incompatibility between certain USB wired mice and the USB 3.0 ports on my MBP, under El Capitan. (USB support was changed in El Capitan and there were USB problems in releases before 10.11.5.) If you have this problem, try a different mouse.
On two computers upgrading from Yosemite, Photos said it had to convert my library. It took a long time before the progress bar vanished, and then it locked up, using 270% CPU, for over an hour. On a third computer upgrading from Yosemite, with a much smaller Photos library, there was no conversion message or delay.
When I installed iPhone iOS 10.2, my Photos library synced from my Mac via iTunes was messed up: pictures appeared in the wrong folders or were missing or misordered. Google had the solution: delete Pictures/iPod Photo Cache and re-sync.
On two computers, my Sharing preferences were preserved when upgrading from Yosemite. A computer that was upgraded from Mavericks to El Capitan had all Sharing preferences reset to OFF.
Safari 9.1.2 did not work correctly on a computer that was upgraded from Mavericks to El Capitan. Firefox settings such as whether the Favorites bar should be shown were lost. Dropdown menus did not work on a web page, and a Flash applet did not run in the page. Worked OK in Chrome. Safari would freeze solid and would not exit, had to be killed. This was repeatable. (Reinstalled latest Flash. Downloaded and installed the 10.11.6 Combo updater. Didn't help.)
My patch to make the slideshow screensaver hold a picture for 30 seconds was undone, as I expected. I had to boot into recovery mode and disable SIP in order to patch it.
I tried several times to restart holding down command-R to enter recovery mode. It didn't work: the computer started up regular OS X. Finally I shut down the computer and pressed the boot button while holding command-R, and it worked.
Adobe Illustrator CS5 can open files, do some editing operations, and save. It crashes on quit. There is a fix for this: rename /Library/Application Support/Adobe/CS5ServiceManager to CS5ServiceManager.old and similarly rename ~/Library/Application Support/Adobe/CS5ServiceManager to CS5ServiceManager.old. This seems to fix the crashes. There are also online postings saying that using the Eyedropper tool on a gradient will also cause the program to crash; haven't tried it. Illustrator also has the same issues with fonts activated by Suitcase as Photoshop does: see below.
The more I use Illustator CS5 on El Capitan the worse it looks. On one machine, scrolling the Font menu crashes Illustrator: on another, it doesn't. A different computer running El Capitan won't let me copy an object to the clipboard in Illustrator and paste into Photoshop.
I guess the long-run solution that preserves the most function is to replace Illustrator CS5 with an up-to-date program. Unfortunately, Adobe no longer supports CS5 with patches, and no longer sells CS6; my options are to subscribe to Illustrator CC ($20/mo), or buy an alternate product, like Affinity Designer (which lacks some Illustrator features).
Adobe Photoshop CS5 can open files, do some editing operations, and save. I thought it worked until I tried to edit a file that used a font already activated by Suitcase Fusion 7 (see below). Photoshop could not see the font. It complained and substituted another font. The font was not visible in the font menus.
Again, the 'official' solution is to buy a subscription to Photoshop CC for another $20/mo, or buy an alternate product, like Affinity Photo and learn how to use it.
Extensis Suitcase Fusion 7 is recommended for use with El Capitan. Unfortunately, it does not support Illustrator or Photoshop CS5. The old font activation plugins for these programs don't work with Fusion 7: they produce an error message. No new font activation plugins are provided for CS5 by Extensis. It looks like I bought Fusion 7 but it is worthless to me unless I buy the Adobe CC versions of Photoshop and Illustator.
Getting Contacts correct after installing El Capitan took me many hours of work. A family member's computer is still on Mavericks. Its Contacts preferences point to two iCloud contacts, mine and another. Opening Contacts on the Mavericks machine seemed to duplicate almost every contact and every group on both computers and my iCloud account.
I saved my contacts to a VCF file. Then I disabled my iCloud account in Contacts, expecting to see my 'On My Mac' copy. Instead I saw no contacts at all. I tried to import the VCF file, but only the first 70 contacts were imported. I noticed some very strange data items in one contact in the VCF file, such as X-MS-CARDPICTURE, X-MS-OL-DEFAULT-POSTAL-ADDRESS and X-MS-OL-DESIGN; and this contact contained repeated identical fields and data full of NUL characters, looked like Unicode. That was about contact number 70. I think the import silently aborted on it. (The contact resulted from importing address data from an Outlook mail message under Mavericks, won't do that any more.) The format of VCF contacts seems to have changed slightly since the previous version: multi-line addresses sometimes have a newline instead of two fields.
Under Yosemite, my Mac would wake up silently in the night and download mail. It doesn't do this under El Capitan, even though Power Nap is enabled in the Energy Saver control panel.
Secure Erase has been removed from the Finder. There is no way to securely erase files from a Solid State Disk (because of the way SSD deletion works), and Apple apparently chose not to have a feature that would only work sometimes. (If you have files that you know are stored on a magnetic hard drive, you can enter Terminal and delete them with the srm command.)
Disk Utility in El Capitan cannot set up a RAID configuration, according to MacInTouch. If you have set one up in Yosemite, it will still work. Disk Utility in El Capitan no longer has the ability to burn a CD or DVD: you can still do it from the Finder.
Keep a list of the software and devices you use and depend on, so you can check that they are supported.
The next version of what will now be called 'macOS', version 10.12 'Sierra', will release in Fall 2016. Beta versions are available now. It will feature further integration with the iPhone and the iWatch. Macs older than 2009 will not be able to upgrade.
