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.

A quick upgrade guide has been posted on

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.

Mid 2011 Mac Mini Os Upgrade Pack

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):

Aluminum 'Unibody' Mac mini Q&A

How do you upgrade the RAM in the Aluminum 'Unibody' Mac mini models? What type of RAM do they use? How much RAM do they actually support? Is it even possible to upgrade the RAM?

There are five different lines of Aluminum 'Unibody' Mac mini models -- the 'Mid-2010', 'Mid-2011', 'Late 2012', 'Late 2014' and 'Late 2018' -- all of which are quite different from one another in terms of memory.

Although the memory types are different, the upgrade procedure for the 'Mid-2010', 'Mid-2011' and 'Late 2012' Mac mini lines is easy and essentially the same and it is quite similar for the current 'Late 2018' models, as well. Unlike vintage polycarbonate Mac mini models, which require one to pry open the case and are not easy to upgrade, these Aluminum Mac mini models have a black plastic base on the bottom that can be removed with a quick turn to access the RAM slots.

Unfortunately, as first reported by Macminicolo and confirmed by site sponsor OWC, the now discontinued 'Late 2014' Mac mini models have soldered RAM. These models could be upgraded to as much as 16 GB of RAM at the time of system purchase, but the RAM cannot be upgraded later at all. In a pleasant surprise, Apple returned to upgradable memory for the current 'Late 2018' Mac mini models (sadly the storage is onboard, though).

Identification Help

If you're not sure which Aluminum Mac mini model you have, these models can be identified by the Model Identifier in software and externally by EMC Number for the purposes of upgrading the RAM. More details about specific identifiers are provided in EveryMac.com's extensive Mac Identification section.

To locate the model identifier in software, select 'About This Mac' under the Apple Menu on your computer and click the 'More Info..' button. If the Mac mini is running OS X 10.7 'Lion' or later, you will need to click the 'System Report' button after clicking 'More Info..' as well. EveryMac.com has carefully hand documented each model identifier for your convenience.

For the pre-Late 2014 Mac mini models, the EMC number is visible upon removing the bottom 'spin off' panel to the right of the memory slots (when the ports are facing you). It is on the bottom of the 'Late 2014' and 'Late 2018' models toward the ports. As always, EveryMac.com has hand documented the EMC numbers unique to each series, too.

These identifiers are most easily visualized as a chart:

EveryMac.com's Ultimate Mac Lookup feature -- as well as the EveryMac app -- also can identify these models by their Serial Numbers.

RAM Types & Actual Maximum RAM Capacities

The 'Mid-2010' Mac mini models have two memory slots that support 1066 MHz PC3-8500 DDR3 SO-DIMMs. Originally, they both officially and unofficially supported a maximum of 8 GB of RAM with two 4 GB memory modules. However, as discovered more recently by site sponsor Other World Computing, if these systems are running OS X 10.7.5 or higher, have been updated to use the latest EFI, and are equipped with proper specification memory modules, they can support up to 16 GB of RAM with dual 8 GB memory modules.

The 'Mid-2011' Mac mini models likewise have two memory slots but instead support faster 1333 MHz PC3-10600 DDR3 SO-DIMMs. Officially, these models only support 8 GB of RAM, but as also reported by OWC, they likewise are capable of supporting 16 GB of RAM with dual 8 GB memory modules. These models only run OS X 10.7 and later versions of the operating system.

The 'Late 2012' Mac mini models also have two memory slots but use faster still 1600 MHz PC3-12800 DDR3 SO-DIMMs. At least for now, they both officially and unofficially support 16 GB of RAM, but should this number increase in the future (Intel reports that the underlying chipset can support up to 32 GB of RAM), this EveryMac.com Q&A will be updated.

Unfortunately, the 'Late 2014' Mac mini models have soldered RAM that cannot be upgraded after the initial system purchase. By default, these models have 4 GB or 8 GB of 1600 MHz 'Low Power' LPDDR3 SDRAM onboard, and this can be upgraded to 16 GB, but only at the time of initial purchase. The RAM in these models cannot be upgraded later.

The current 'Late 2018' Mac mini models triumphantly return with two memory slots and use even faster 2666 MHz PC4-21300 DDR4 SO-DIMMs. They support as much as 64 GB of RAM with two 32 GB memory modules.

Much like the identification help, the details are most easily visualized as a chart:

* Officially, the 'Mid-2010' models support 8 GB of RAM, but they actually can support 16 GB of RAM. However, this is if and only if they are running OS X 10.7.5 or higher, have been updated to use the latest EFI, and are equipped with proper specification memory modules.

† Officially, the 'Mid-2011' line supports 8 GB of RAM, but they actually support 16 GB.

‡ The 'Late 2014' Mac models support a maximum of 16 GB of onboard 1600 MHz 'Low Power' LPDDR3 SDRAM, but only if configured with 16 GB at the time of system purchase. The RAM cannot be upgraded later.

RAM Upgrade Instructions

For polycarbonate Mac mini models, Apple does not provide instructions or recommend that users upgrade their own memory. However, for the Aluminum Mac mini, the company provides instructions on pages 31-38 and 39-46 of the 'Mid-2010' and 'Mid-2011' User's Guides, respectively. Apple does not provide instructions in the 'Quickstart Guide' for the 'Late 2012' models, but the procedure is the same. Apple likewise does not provide instructions for the current 'Late 2018' models, but it is a similar process, as well.

When available, the manuals provide installation instructions complete with drawings, which absolutely should be reviewed in their entirety before one installs memory. However, the below videos may be even better.

Mid-2010 Mac mini RAM Upgrade Videos

This video -- from YouTube user DetroitBORG -- specifically covers the optical drive-equipped 'Mid-2010' (Macmini4,1) models:

Mid-2011 & Late 2012 Mac mini RAM Upgrade Video

OWC provides an exact video covering the slotless 'Mid-2011' (Macmini5,1, Macmini5,2, Macmini5,3), and 'Late 2012' (Macmini6,1, Macmini6,2) models, too:

Late 2018 Mac mini RAM Upgrade Video

Finally, OWC provides a specific video for the current 'Late 2018' (Macmini8,1) models:

After watching these videos, it should be clear that upgrading the RAM is a simple procedure in aluminum Mac mini models released prior to and after the Mid-2014 series.

However, even though the RAM upgrade procedure is simple (when possible), if you do not feel comfortable -- or have the time -- to perform the upgrade yourself, hiring a professional always is a good option.

Mac mini RAM Purchase Options

Just because RAM meets the minimum listed criteria does not mean that it will necessarily function as intended in your Mac. Be sure to buy from a quality vendor that has tested their RAM with the Mac mini to ensure full compatibility.

In the US (and many other countries), site sponsor Other World Computing sells memory compatible with all of the Mac mini models and provides a professional upgrade service for the Mac mini, too.

In the UK and Ireland, site sponsor Flexx sells Mac mini compatible memory with free shipping. The company provides flat rate shipping to France, Germany, and Switzerland and inexpensive shipping for all of Europe, too.

In Canada, site sponsor CanadaRAM sells memory for all Mac mini models with guaranteed compatibility, fast shipping, and no customs.

In Germany, site sponsor CompuRAM sells quality memory for all Mac mini models with affordable delivery country-wide and in person pick up and professional installation service available in Munich.

In Australia, site sponsors Macfixit and Upgradeable sell Mac mini compatible memory with fast shipping, a money-back guarantee and more.

In New Zealand, site sponsor Upgradeable New Zealand sells Mac mini memory with fast delivery to all corners of the country, precise compatibility, a lifetime warranty, and a money-back guarantee.
