This tip replaces version 2126 originally released on the Discussions Feedback forum.
Boot Camp needs Mac OS X 10.5 or later on Intel Macs. Note other virtualization tools are available for Mac OS X 10.4.11 or earlier on Intel Macs. Mac OS X 10.7.3 is needed for the latest Java and minimum iCloud. The same minimum system requirements exist for Mac OS X 10.8, 10.9, 10.10, and 10.11. Step 2: To confirm the layout, OS X will ask you to press certain keys Step 3: So that all the characters can be correctly identified, OS X will ask you the layout type. Once OS X has configured the keyboard, it’s ready to go. What you’ll find is that you might want to remap those Alt and Windows keys. You’ll find accents associated with the following keys: e, y, u, i, o, a, s, l, z, c, n. Typing emoji on a Mac. You might think that emoji are restricted to iPhones and iPads, but they aren't. This operating system allows you to use the special characters which are not on your keyboard. Following are the three ways which will enable you to write special characters in Mac OS X. Holding down of Keys: If you are looking to type some characters which are modified versions of common letters you can use the holding down key approach.
Find the serial number on:
Plug your serial number in at this link:
Do not use third party links as they may not be secure.
Do not post the serial number on this board, as that is your key to any support you may have left.
Use this tip also to help figure out which portion of the Support Community to post in, as this tip explains:
When you have no serial number, use one of these third party sites to find your model, production year, time in year
(early, middle, late, summer, fall, winter, spring):
Note:
PowerMac, PowerPC, eMac, iMac PPC, iBook (Apple recycled the name iBook for its eBook application on new Macs and iOS devices), Powerbook, Classic all refer to Macs that are older than the present series
of Macs. Posting in those forums about a current Mac, shows you have not researched your Mac sufficiently to get a succinct answer to your query. Apple menu -> About This Mac will tell you the Mac OS version or System version you are running. The X in the version is important, and so is the preceding 10 in the version if it exists.
Questions saying X.1 could refer to Mac OS X 10.13.1, 10.1. Don't truncate the version you see.
There are no iOS forums specific to the operating system found on iPads, iPod Touch, AppleTV, Apple Watch, and iPhones. Figure out the type of portable device you are running to ask a question about that device specifically.
Apple has these identifying articles as well:

Macs generally will not run an older Mac OS X operating system than shipped with them.
The one exception is virtualizing 10.6 Server on 10.7 or later, which is described later.
Also important to note is that the Apple App Store only has 10.7, 10.8, and 10.12, except for those who purchased in between systems, and have a Mac that shipped with in between systems. For all others if you need an in between system, and your Mac is older, contact the App Store tech support.

The oldest MacBook Air and iMac that can run Mac OS 10.14 after installing 10.11.
• MacBook Air 5,1
• iMac 12,1

July 20, 2011 will only run 10.7 or later. The model IDs (x,x) and EMC that fit this description until June 25, 2012 release of 10.8 (excluding the ones which will run only 10.8 or later earlier mentioned) :
iMac of an EMC of 2496; 13,x and later.
Mac Mini 5,x and later.
Macbook Air 4,x and later.
MacBook 8,x and later (no Pro no Air in the name)
Mac Pro 5,1 with EMC 2629 - the oldest that can be have Mac OS 10.14 installed after installing 10.11 or later, those without that EMC number came with 10.6 and can also be updated to 10.14 the same manner; 6,x and later.
MacBook Pro with EMC 2555, 2563; 9,x and later.
Note all the Macs that can only run 10.7 and later, may be able to run 10.6 Server with Parallels, if you need compatibility with an older operating system:
Beyond this point Macs released during certain date ranges also have a maximum operating system, and/or
minimum retail operating system and system specific operating system requirement (when I say up to 10.9 that includes all incremental updates):
Note: images shown below for retail operating system are those that have no 'Update, Dropin, or OEM' wording on them.
March 15, 2010-July 19, 2011 will only run prebundled 10.6 installer disc, and not retail, but also able to be upgraded to 10.9. Note this tip
if upgrading to 10.7 or later: https://discussions.apple.com/docs/DOC-6271
August 28, 2009-March 14, 2010 will only 10.6 or later up to 10.9. And will at minimum be able to use
10.6.3 retailto install 10.6. Note this tip if upgrading to 10.7 or later: https://discussions.apple.com/docs/DOC-6271
During 2000 to 2009, the serial number also made it easier to identify the Macs, as the 3rd, 4th, and 5th character of the serial number referred to the week
and year of the shipment date. Thus for serial numbers where x can be any letter or number, xxABCxxxxx serial numbers would refer to an A which is the last digit of the year, and BC=week of the year. xx905xxxx is the fifth week of 2009. You can then use Wikipedia to figure out what date the release was, and if it was after a specific retail release of an operating system to determine which pre bundled disc it came with, and which later retail discs the Mac could work with.
December 15, 2008-August 28, 2009 will only run prebundled 10.5 installer disc, and 10.6 retail https://discussions.apple.com/content/attachment/43236040snow.jpg, and if on https://discussions.apple.com/docs/DOC-3761
will also run up to Mac OS X 10.11 if you follow this tip: https://discussions.apple.com/docs/DOC-6271
October 28, 2007 -December 14, 2008 will at minimum be able to use the 10.5.6 retail, and install up to 10.9 if included on https://discussions.apple.com/docs/DOC-3761 if you follow this tip https://discussions.apple.com/docs/DOC-6271
January 10, 2006-October 27, 2007 will at minimum be able to 10.5 retail, and if
on Which 10.5 systems can upgrade to 10.8 or 10.9?or Are there 10.4 systems that can upgrade to 10.8 or 10.9? are
able to run 10.9. Core2Duo and Xeon can upgrade to a minimum of 10.7.5. Otherwise if they only have a CoreDuo, CoreSolo Intel
processor only be able to upgrade to Mac OS X 10.6.8. G5, G4, and G3 processors are not Intel.
Earlier dates are covered on this tip:Can I download my Mac OS upgrade?
Using the dates from the above documents, and the dates according to Wikipedia when specific retail
operating system systems were released, you can find which retail releases were newer than the Macs and the ones immediately older.
i.e.:
An October 24, 2011 Macbook Pro will only run 10.8 retail, and 10.9 retail downloads, but needs an
AppleCare requested 10.7 installer to install 10.7. An exception exists in 10.6 Server, as indicated here:
A pre-October 26, 2007 MacBook Pro will only run the system specific Mac OS X 10.4 installer
that shipped with it, which can be ordered from AppleCare, or newer retail installer versions
of 10.5, 10.6 compatible with its hardware, and 10.7 if it is at least a Core2Duo.
CoreDuo, nor is CoreSolo is not compatible with 10.7.
For PowerPC Macs, Mac OS X 10.4.11 and earlier offer Classic compatibility, and on certain 2003 and earlier Macs dual booting on Mac OS X 10.5 & Mac OS 9:
No Mac may run an older version of Mac OS 9 than was prebundled with it.
A more precise timeline of Mac OS X follows (in U.S. date notation. Links to relevant articles up to 10.7 are included, as 10.7 drops PowerPC applications on Intel):
