- 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.
- Mac OSX El Capitan 10.11.1 is a worthy upgrade from Mac OS X 10.10.5 Yosemite. So glad Apple fixed the bug with Microsoft Office 2016 for Mac! After and initial install process, the computer was slow for about 5 minutes due to optimizing but after a reboot everything was well. Nice and snappy.

Chrome on windows 10s. Mac OS X El Capitan can be downloaded directly from the Apple website. The Beta version of the OS is available but the final version will be made available towards the Autumn season of 2015 as speculated by many Apple users. You can use your older Mac OS with the new El Capitan, all you have to do is to create a different partition for the new El Capitan if you have the Yosemite already installed. There are few steps you should consider in downloading the latest El Capitan and these are as follow.
Part 1. Preparing Mac Device for the Installation of Mac OS X El Capitan
Both Mavericks and Yosemite are easier to download and install on Mac devices, however, this is not the case with Mac OS X El Capitan. Just before you install the new Mac OS X El Capitan, you must perform few tasks to ensure that your Mac will be ready for the installation of the software:
The OS X El Capitan v10.11.6 Update improves the stability, compatibility, and security of your Mac, and is recommended for all users.
- Check Your Mac - Check whether your Mac will be able to run the new OS X 10.11. Apple has provided a list of the Mac supported by the new Mac OS X El Capitan and if you are already running the Mavericks or Yosemite, the same lists may also apply to the El Capitan. You can also check this list on the 'Will your Mac run Mac OS X' article on Apple website.
- Create Enough Space - Check that your Mac has sufficient RAM to run the software. You wouldn't run into any hitches if your Mac device is listed on the acceptable Mac devices for Mac OS X El Capitan. Apple recommend that you have a minimum RAM of 2G, however, a minimum of 4G space of RAM is highly recommended. You will also need to delete some unnecessary files to create more space for the installation of El Capitan.
- Check Hard Drive Space - Make sure you have sufficient hard drive space for the installation of Mac OS X El Capitan. Yosemite will normally require a Hard drive space of up to 5GB , but the new El Capitan will require between 15g and 20gb of space on your hard drive for successful download and installation.
- Register - Register to access the Mac Apple store. You need to upgrade your Mac and get access to Mac Apple store for a small fee in order to get the most out of your Mac OS X El Capitan.
- Updates - Make sure your third party Apps are updated before installing Mac OS X El Capitan. You can simply launch App store and click on 'Updates' on the tool bar if you want to update the apps you bought from Apple store. For other third party apps, you may need some manual updates from manufacturer websites to complete such updates.
- Backup Your Mac - Perform a backup before downloading and installing Mac OS X El Capitan- you need to protect your important documents and files, thus you may have to back them up somewhere before starting the download and installation process.
Part 2. Installing Mac OS X El Capitan Safely on Your Mac Device
You can install or upgrade to Mac OS X El Capitan as a dual boot partition. You may be able to download a test version if you register for the OS X Seed program from Apple, and you can also provide a feedback to Apple in order for the company to update the software before it is finally released. You can follow these instructions to install the Beta version of Mac OS X El Capitan. It is strictly recommended that you perform a backup before you begin this process. It is important you keep in mind that Mac OS X El Capitan is still in a Beta format, thus , not all your apps or programs will work on it.
- Visit the Apple Beta software program page and log unto the page using your Apple ID. Simply click on 'Enroll your Mac'.
- Click on the download link that shows up, and enter the personal redemption code given to you.
- Open the downloaded Mac OS X El Capitan software and preview the file in the Applications folder. Click 'Continue' and then select 'Agree'.
- Click on 'Install' and then enter your admin password. You're all set!
Part 3. Installing Mac OS X El Capitan Safely on an External Drive
You don't have to install Mac OS X El Capitan on your Mac device, you can also install it on an external hard drive, most especially when you want to access the OS quickly. You can consider Thunderbolt drives which are similar to the internal drives on Mac, or you can simply use the USB 3.0 external drive if you don't have the Thunderbolt on your Mac. You will have to format an external drive before installing Mac OS X El Capitan, this will help to install the Mac OS X El Capitan safely on the hard drive and at the same time the configuration of your device will not be changed.
Step 1. Launch Disk UtilityConnect the external drive to your Mac device and make sure it is detected. Launch the Disk Utility tool ( go to 'Utilities' and you will find it there). Choose the drive- it is located at the side bar.
Step 2. PartitionSimply click on 'Partition'. Make sure the partition layout reads '1 partition'. Name the partition. You can use a name like 'Mac OS X El Capitan'. Click on 'Options' and ensure that the Guide partition table is chosen, and then click on 'Ok'.
Step 3. OptionsClick 'Apply'. Open the preview file from your Mac's application folder. Click on 'Continue'. Click on the 'Agree' button.
Step 4. OpenClick on 'Show all disks'. Simply highlight the 'External Hard Drive' on which you have just install the Mac OS X El Capitan
Step 5. InstallClick on 'Install', and enter the admin password.

Note: The Days column reflects the number of days between releases.
Some entries may appear out of chronological order (i.e. 10.5 is shown on Oct 26, but above Nov 14 for 10.4.11). This is to keep the version numbers in the proper order, even when an older OS received an update after a major new release came out. This has happened a few times over the years.
Some random notes, updated from the original post:
- Starting with the Public Beta and up through 11.2.2, there have been 146 macOS releases, both major and minor. This figure includes the one odd macOS X release: 10.2.7. This version was only for the then-new PowerMac G5 and the flat panel iMac G4, and was never generally released.
- As of February 25th, 2021 (11.2.2's release date), it's been 7,470 days since the Public Beta was released. So on average, we've seen some sort of update every 51.2 days.
- The shortest time period between any two releases is six days, which is how quickly the 10.15.5 Supplemental Update 1 came out after the 10.15.5 release.
- The longest time period between any two minor releases is 165 days, which was how long we waited for the 10.4.9 update. (Tecnically, it's actually the 192 day interval between the Mac OS X Public Beta and version 10.0, but I'm counting from the official 10.0 release.)
- The smallest update was 10.3.1, at only 1.5MB. The largest (non-combo, non-main OS release) update was 10.15.1 at 5.3GB.
- The '???' entry for Size on a given release indicates I was unable to find the size. Feel free to contact me if you can help replace any of the '???' entries.

Note: The Days column reflects the number of days between releases.
Some entries may appear out of chronological order (i.e. 10.5 is shown on Oct 26, but above Nov 14 for 10.4.11). This is to keep the version numbers in the proper order, even when an older OS received an update after a major new release came out. This has happened a few times over the years.
Some random notes, updated from the original post:
- Starting with the Public Beta and up through 11.2.2, there have been 146 macOS releases, both major and minor. This figure includes the one odd macOS X release: 10.2.7. This version was only for the then-new PowerMac G5 and the flat panel iMac G4, and was never generally released.
- As of February 25th, 2021 (11.2.2's release date), it's been 7,470 days since the Public Beta was released. So on average, we've seen some sort of update every 51.2 days.
- The shortest time period between any two releases is six days, which is how quickly the 10.15.5 Supplemental Update 1 came out after the 10.15.5 release.
- The longest time period between any two minor releases is 165 days, which was how long we waited for the 10.4.9 update. (Tecnically, it's actually the 192 day interval between the Mac OS X Public Beta and version 10.0, but I'm counting from the official 10.0 release.)
- The smallest update was 10.3.1, at only 1.5MB. The largest (non-combo, non-main OS release) update was 10.15.1 at 5.3GB.
- The '???' entry for Size on a given release indicates I was unable to find the size. Feel free to contact me if you can help replace any of the '???' entries.

A special 'thank you!' goes to Mr. Ziebell (for providing some size values on very-old minor updates), and to Benton Quest (for providing size info on all the major releases up through Snow Leopard). See Benton's comment below if you want a nicely detailed history of those early releases.
