2011-09-24: New Mac OS X package for version 1.5.0: Steve sent in a better (more user-friendly) Mac OS X package for uHexen2 version 1.5.0: updated on the downloads page. 2011-09-19: Hammer of Thyrion version 1.5.0 is released. Update your Mac (OS and hardware) Typically, Macs take care of themselves. Having the latest software from Apple makes speeding up your Mac simple. To check your version of the operating system, click the Apple icon in the top left corner of your screen and then About This Mac. The Power Mac G4 Cube models can run MacOS X as well up to MacOS X 10.4.11 'Tiger' as supported by Apple. Is there a 'hack' to make MacOS X 10.5 'Leopard' run on the Power Mac G4 Cube? Officially, the Power Mac G4 Cube is only capable of running MacOS X 10.4.11 'Tiger' and lower. We'd like to update you on the development and certification process regarding Mac OS X 10.11 (El Capitan) for current Steinberg products. You can find a list of Steinberg applications that we have tested for Mac OS X 10.11 below. For newer products, check the corresponding product pages and the system requirements on supported operating systems. The maximum version of Mac OS X, OS X, or macOS supported by each G3 and later Mac follows. For complete specs on a particular system, click the name of the Mac. For all Macs that are compatible with a specifc maximum supported version of Mac OS X - courtesy of EveryMac.com's Ultimate Mac Sort- click the OS of interest. Systems with 'Current.
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.

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):

Which Mac operating system is the best is a topic of numerous debates among Apple fans. 
Since the mission of this blog is to refute myths and legends around Macs, it's time for me to provide my 2 cents about the issue on hand. While everything below is just my opinion, as a long-time Mac user and veteran software engineer, I hope my opinion worth something.
The best Mac OS version is the one that your Mac is eligible to upgrade to. In 2021 it is macOS Big Sur. However, for users that need to run 32-bit apps on Mac, the best macOS is Mojave. Also, older Macs would benefit if upgraded at least to macOS Sierra for which Apple still releases security patches.
How to Tell Which macOS You Are RunningTo find out which macOS is currently running on your Mac, follow these steps:
Click on Apple logo in the top left corner of the menubar
In the dropdown click on the first item: About This Mac
The first line in the Overview tab is the name of the current OS.
What Version of OS Can My Mac Run?Not all Macs can be upgraded to the latest OS version. For instance, old Macs powered by PowerPC CPUs cannot run OS intended for Intel-based computers. Also, some versions have hardware limitations. 
For instance, Mojave cannot be installed on MacBook Pro earlier than Mid 2012 model.
Check below to know exactly what version of OS your Mac can run.
Which OS is Best for my Mac Anytime someone asks me which OS is best for them I always suggested going with the latest. Things have changed recently, however. 
Should I Upgrade to macOS Catalina or Big Sur?While personally I like macOS Big Sur and have it installed on my MacBook Pro, it comes with serious breaking changes. 
The first issue is compatibility.
Big Sur is a transition OS which is designed to help Apple to move from Intel processors to their own chips on ARM. 
After I installed Big Sur on my MacBook Pro mid 2020 (pre-Silicon), most of my apps, including Microsoft Office, were working as expected. 
However, my VMWare Fusion 11 does not start anymore, so I have to purchase a new license if I want to keep using it (or roll back to Catalina). Luckily, I took a full backup before the upgrade.
The second breaking issue is the lack of 32-bit app support.
macOS Catalina and Big Sur can only run 64-bit apps. 
If you wondering whether you should upgrade to macOS Catalina or Big Sur, first verify that you don't have any 32-bit apps. But first, take a back up, so you can go back in case something breaks after the upgrade.
For instance, I had to remove uTorrent after upgrade. And I didn't know that uTorrent is 32-bit!
How to Know If App is 32-bit or 64-bitTo find out whether the app on your Mac is 32-bit or 64-bit follow these steps:
Click on Apple logo in the top left corner of the Mac screen
Click on About This Mac option
Click on System Report button in Overview tab (first one)
Scroll down to Software -> Applications
Find the app and check Kind
Which macOS Should I UseIf you have an older Mac which is not eligible to upgrade with some latest software or hardware, I'd suggest upgrading at least to Sierra (or better High Sierra) for the following reasons:
Sierra is still supported by Apple, and it gets security updates
APFS file system is available
It supports Siri
Significant security improvements
The most important point when choosing the best OS is the ability to get security updates. While Apple generally does not announce the OS end of life dates, it is possible to know when they stop releasing security updates from this page. 
For instance, according to the page, the last security update for OS X Yosemite was released on September 12, 2017. The last update for OS X El Capitan was in July 2018, and Carnegie Mellon University confirmed that El Capitan's end of life date was August 2018. 
Snow Leopard MythI know that some users on forums believe that the best OS version for Macs was Snow Leopard. But that is a myth. And I know how such myths get created.
Once I worked in the company, which was selling a 20-year old product. And customers were still using and didn't want to switch to new versions, because the old one was rock solid. 
I then talked to the engineer who worked on the project, and he revealed that the product was a total disaster when it was first deployed. Engineers had to work on-site for almost a year in order to fix all bugs. 
After five or so years of polishing the product, it becomes virtually bug-free, and nobody now remembers how bad it was when it was first rolled out. A similar thing happened Snow Leopard, and it was recognized as best mac os version after some time.
How to Update to the Latest VersionThere are two ways to update to the latest OS version on Mac:
From the Software Update section in System Preferences
Use a download link
Using Software UpdateThis is by far the best option, but it only available if you have Yosemite, or later OS installed already. If you enabled automatic updates, then Mac will inform you that the next macOS is available.
Just open System Preferences, go to Software Update and click on the Upgrade Now button.
This method is also best if wondering how to check if you have the latest version of OS installed on your Mac. Only the version compatible with your hardware will appear here. 
For instance, my the latest version for Mac Mini 2012 is Mojave, I can't install anything newer than that.
If you are having problems with updates or having issues post-upgrade check my post about troubleshooting macOS.
Using download linksFor older systems or in case you need to downgrade, you have to download a standalone installer in DMG format. DMG stands for disk image, similar to ISO, just different formats.
After downloading the installer, just double click on it and follow instructions. Again, do not forget to take a backup before the upgrade.
Mac OS Comparisons: Requirements, Features, Compatibility, Download LinksFollowing is a high-level description of all Mac operating systems as early as Mountain Lion. 
You can refer to those descriptions when deciding which operating system is best for your iMac, Mac Pro, Mac mini, or MacBook.
With each OS description, I included a list of Macs supported. However, you can use Mac OS compatibility checker for more detailed information.
