Mac OS X & macOS names. As you can see from the list above, with the exception of the first OS X beta, all versions of the Mac operating system from 2001 to 2012 were all named after big cats.

Officially, the operating system that was available on that Mac at the time that you bought it is the oldest version of macOS that can run on that Mac. It's likely that an older OS won't include.
Wouldn’t it be nice if you could have all three major operating systems (OS X, Windows, Ubuntu Linux) running on your computer! This is totally possible with a Mac. Here is how to do it.
You might be asking yourself why would someone want to be able to run three operating systems on one device. There are some programs, apps and games that are system specific. Some older PC games can only run on Windows. Some programs are only OS X compatible and vice versa. Some individuals might need run company-specific software that requires Windows or a Linux operating system but might prefer Mac’s OS X operating system for personal use and don’t want to use multiple computers or be stuck using an operating system they are not familiar with. For these individuals installing multiple operating systems on a Mac is a convenient feature.
1. In OS X, remove the Core Storage designation from your OS X partition.
2. Launch OS X Bootcamp. Create a Windows installation USB drive (I've created both Windows 8 and 10) and create a hard drive partition for Windows.
3. When the Mac reboots into the Bootcamp Windows installer, hold down the power button to shut down, then press and hold Option+Power to restart into the Mac bootloader. Select and boot the OS X partition.
4. In OS X, run Disk Utility. Reduce the size of the OS X partition, then create a new partition for Ubuntu in the empty space. File format on the Ubuntu partition shouldn't matter at this point. I used FAT.
5. Create an Ubuntu installation disk whatever way you prefer with (I believe) whatever version you prefer.
6. Shutdown again and hold Option+Power restart to get to the Mac bootloader, then select the Ubuntu install disk (should be labeled EFI, there might be two of them, either should work). Reformat the partition you created in Step 4 for Ubuntu and complete the installation process, then shutdown. (If you reboot into the Mac bootloader at this point, Ubuntu should not be visible).
7. Power (not Option+Power) restart. Your Macbook should boot into the Bootcamp installation partition. Complete the Windows installation process normally. The Macbook will reboot several times. If ever it reboots into the wrong partition (it shouldn't), then manually shutdown, Option+Power boot, and select the Bootcamp partition manually.
8. Almost done. After Windows is fully installed and you can use it normally, Option+Power reboot into OS X, then install rEFInd.
Shutdown and perform a regular boot. You will arrive at the rEFInd menu with a 20-second timer, and all three OS’s should be visible. rEFInd is a handy piece of software that allows you to easily select the OS you want to boot into whenever you restart your Mac.
Note 1:
I have had the problem, twice now, that whenever I install OS X updates, rEFInd disappears. When I power on the computer, it boots straight to OS X. This problem is fixed by simply reinstalling rEFInd from within OS X. Back to normal.
Some users might receive errors when returning to the Windows installation process. Julian Leland recommends clearing the hybrid MBR data from within OS X via this process.
Is your Mac up to date with the latest version of the Mac operating system? Is it using the version required by a product that you want to use with your Mac? Which versions are earlier (older) or later (newer, more recent)? To find out, learn which version is installed now.
If your macOS isn't up to date, you may be able to update to a later version.
From the Apple menu in the corner of your screen, choose About This Mac. You should see the macOS name, such as macOS Big Sur, followed by its version number. If you need to know the build number as well, click the version number to see it.
These are all Mac operating systems, starting with the most recent. When a major new macOS is released, it gets a new name, such as macOS Big Sur. As updates that change the macOS version number become available, this article is updated to show the latest version of that macOS.
If your Mac is using an earlier version of any Mac operating system, you should install the latest Apple software updates, which can include important security updates and updates for the apps that are installed by macOS, such as Safari, Books, Messages, Mail, Music, Calendar, and Photos.
