iMac Late 2009 - 2011

The iMac Late 2009 revision replaced the previous generation's 24" with the new big 27" display. The smaller 20" model was also upgraded a bit to 21.5". The lower end Late 2009 models still used the Intel Core 2 Duo CPU, but some of the 27" 2009 models, and all subsequent models, moved to the more advanced Core i3/i5/i7 chips. Thunderbolt was added to the iMac range with the 2011 model.

All of these machines have user accesible RAM sockets along the bottom of the screen. The drives can also be replaced without too much trouble (at least compared to the next revision) - the outer screen glass is held on magnetically and can be removed using suction cups. There is an annoying issue with the hard drive temperature reading when using third party drives, but this can be resolved with software. Replacing the hard drive with an SSD (Solid State Disk) and upgrading the RAM can make these machines still useful for lighter tasks into the 2020s (though not if you need to run the latest versions of macOS). We sell RAM and drives for these machines, and offer installation services performed by technicians with over 10 years experience with these machines.

We offer repair services for the iMacs, and can replace faulty drives and other components. The achilles heel of these iMacs has been their graphics cards. While not as common as the similar problems with some 2011 MacBook Pros, GPU failures are unfortunately a known issue. The problem is common enough that replacing a faulty graphics card is not really viable - there is simply no source of reliable cards (and plenty of sources of unreliable ones). Over the years we have had a lot of experience in doing a temporary reflow repair of these iMacs graphics cards, but this is a way of prolonging their life that does not fix the underlying fault - after some undeterminable period of time, the fault will recur. Given the age of these machines now, it makes a lot less economic sense to spend money on a temporary fix than it once did, and we sadly advise most people to consider replacing the machine these days.

All these iMacs can run versions of macOS up to and including 10.13 High Sierra.

      • Part Number 

        The MPN (Marketing Part Number), also sometimes called the model number, marketing number, order number or part number. This is the part number under which Apple sold this particular Mac model. Only base configurations have part numbers, while Macs sold with various build to order/configure to order options do not have them. What we consider a single Mac may have multiple part numbers, which may refer to different specifications of RAM, drive size, or case colour that were offered as base options. Part numbers also differ by country or region.

        In modern Macs it is usually an 8 or 9 digit code, with the last 2 characters being "/A" or occasionally "/B". The one or two characters immediately before the "/" depend on country or region - "B" is the UK, "LL" the USA, etc. We represent this portion as "xx".

      • EMC Number 

        EMC numbers cover a narrow group of Macs, or sometimes an individual machine. There are exceptions, but usually models that share an EMC number were released at the same time, and share all attributes apart from minor differences in CPU and other internal components. In a very few cases, Macs of the same model were sold with multiple different EMC numbers.

        The EMC number is usually a 4 digit numerical code, though in a few cases there are additional characters.

      • Model Identifier 

        Model Identifiers often cover a narrow range of Macs. Usually one particular type of Mac, with a specific screen size, released at a particular time. Though in some cases a later revision that is substantially similar, will carry the same Model ID.

        Staring with the Intel Macs released in 2006, Model IDs were in the format MacNameX,Y where MacName is a recognisable Mac model (iMac, MacBookPro etc.), and the X and Y are numbers.

        However in 2022, a couple of years after the ARM switchover, Apple started using the format MacX,Y - the X and Y are numbers, but the "Mac" is the same across different models.

        Old pre-Intel (PowerPC) Macs were almost all PowerMacX,Y or PowerBookX,Y (the exception being the very first iMac, which is: "iMac,1").

      • Model Number 

        Model numbers, also sometimes called family numbers, are an identifier that often cover a fairly wide range of Macs. In cases where the fundamental design of a Mac has remained mostly unchanged, but incremental upgrades have been made to internal components, a single Model Number can cover more than 20 individual Macs, released over several years. Other Model Numbers are unique to a single machine.

        It is usually a 5 character code in the format AXXXX, where the Xs are numerals. Some very old Macs have a Model Number that starts with an "M" rather than "A".

        In modern Macs it is usually an 8 or 9 digit code, with the last 2 characters being "/A" or occasionally "/B". The one or two characters immediately before the "/" depend on country or region - "B" is the UK, "LL" the USA, etc. We represent this portion as "xx".

      • EMC Number 

        EMC numbers cover a narrow group of Macs, or sometimes an individual machine. There are exceptions, but usually models that share an EMC number were released at the same time, and share all attributes apart from minor differences in CPU and other internal components. In a very few cases, Macs of the same model were sold with multiple different EMC numbers.

        The EMC number is usually a 4 digit numerical code, though in a few cases there are additional characters.

      • Model Identifier 

        Model Identifiers often cover a narrow range of Macs. Usually one particular type of Mac, with a specific screen size, released at a particular time. Though in some cases a later revision that is substantially similar, will carry the same Model ID.

        Staring with the Intel Macs released in 2006, Model IDs were in the format MacNameX,Y where MacName is a recognisable Mac model (iMac, MacBookPro etc.), and the X and Y are numbers.

        However in 2022, a couple of years after the ARM switchover, Apple started using the format MacX,Y - the X and Y are numbers, but the "Mac" is the same across different models.

        Old pre-Intel (PowerPC) Macs were almost all PowerMacX,Y or PowerBookX,Y (the exception being the very first iMac, which is: "iMac,1").

      • Model Number 

        Model numbers, also sometimes called family numbers, are an identifier that often cover a fairly wide range of Macs. In cases where the fundamental design of a Mac has remained mostly unchanged, but incremental upgrades have been made to internal components, a single Model Number can cover more than 20 individual Macs, released over several years. Other Model Numbers are unique to a single machine.

        It is usually a 5 character code in the format AXXXX, where the Xs are numerals. Some very old Macs have a Model Number that starts with an "M" rather than "A".

        It is usually a 5 character code in the format AXXXX, where the Xs are numerals. Some very old Macs have a Model Number that starts with an "M" rather than "A".

      • Part Number 

        The MPN (Marketing Part Number), also sometimes called the model number, marketing number, order number or part number. This is the part number under which Apple sold this particular Mac model. Only base configurations have part numbers, while Macs sold with various build to order/configure to order options do not have them. What we consider a single Mac may have multiple part numbers, which may refer to different specifications of RAM, drive size, or case colour that were offered as base options. Part numbers also differ by country or region.

        In modern Macs it is usually an 8 or 9 digit code, with the last 2 characters being "/A" or occasionally "/B". The one or two characters immediately before the "/" depend on country or region - "B" is the UK, "LL" the USA, etc. We represent this portion as "xx".

      • EMC Number 

        EMC numbers cover a narrow group of Macs, or sometimes an individual machine. There are exceptions, but usually models that share an EMC number were released at the same time, and share all attributes apart from minor differences in CPU and other internal components. In a very few cases, Macs of the same model were sold with multiple different EMC numbers.

        The EMC number is usually a 4 digit numerical code, though in a few cases there are additional characters.

      • Model Identifier 

        Model Identifiers often cover a narrow range of Macs. Usually one particular type of Mac, with a specific screen size, released at a particular time. Though in some cases a later revision that is substantially similar, will carry the same Model ID.

        Staring with the Intel Macs released in 2006, Model IDs were in the format MacNameX,Y where MacName is a recognisable Mac model (iMac, MacBookPro etc.), and the X and Y are numbers.

        However in 2022, a couple of years after the ARM switchover, Apple started using the format MacX,Y - the X and Y are numbers, but the "Mac" is the same across different models.

        Old pre-Intel (PowerPC) Macs were almost all PowerMacX,Y or PowerBookX,Y (the exception being the very first iMac, which is: "iMac,1").

      • Model Number 

        Model numbers, also sometimes called family numbers, are an identifier that often cover a fairly wide range of Macs. In cases where the fundamental design of a Mac has remained mostly unchanged, but incremental upgrades have been made to internal components, a single Model Number can cover more than 20 individual Macs, released over several years. Other Model Numbers are unique to a single machine.

        It is usually a 5 character code in the format AXXXX, where the Xs are numerals. Some very old Macs have a Model Number that starts with an "M" rather than "A".
