Apple MacBook "Core 2 Duo" 2.4 13" (Black-08)
Early 2008 - MB404LL/A - MacBook4,1 - A1181 - 2242
This machine is in beautiful shape, dropped an SSD in it and maxed the RAM to 6 GB & new battery..
I thought I could upgrade the system beyond 10.7.5 but all the updating procedures seem to be for the MacBook Pros.
Does anyone know if it can be done? I’d like to get it to El Captain.
Это хороший вопрос?

Hi Mayer,
Here is an excerpt of an answer to a similar question which I believe answers yours.
“All MacBook generations after the original MacBook1,1 Core Duo 1.83-2GHz one will run OS X 10.7 (the original MacBook will only run 10.6.8). The three generations shipping in 2007 top out at OS X 10.7.5. The only A1181 MacBooks that will run 10.8 or later are the Early and Mid 2009.”
What is the highest OS X I can run?
Hi Mayer,
Some research into this problem has clarified the issue and potentially solved it?
Lets break down what would prevent you upgrading an old MacBook:
The limiting factor for upgrading an old MacBook is its processors system architecture. Specifically the lack of support for SSE4.1. MacBook Models with a Merom intel core do not support this and as such are structurally incompatible with operating systems past 10.8+.
Luckily, some research into the model of computer you have (MB404LL/A) states that it was one of the few early 2008 MacBook laptops with a Penryn CPU!
However, keep this in mind:
Penryn CPU models T8100, T8300, T9300, T9500 are Penryn processors designed for Santa Rosa Refresh platforms with maximum FSB of 800 MT/s, whereas the rest of the Penryn processors are designed for Montevina platforms that can go up to maximum FSB of 1066 MT/s.
I do not know if this will be an issue when trying to run a newer operating system.
It is also worth noting that the later versions of MacBooks with Penryn CPUs which are “Unofficially” updatable do not use these processors:
Not “Unofficially” Compatible
“Unofficially” Compatible
However, according to LowEndMac.com These MacBook Pro's released in 2008 are also supported, and if you notice, one of them is also running the T8300!
Therefore, you might be able to update your MacBook by following LowEndMac.com’s tutorial even though your MacBook is not “Unofficially” included.
I hope this revised answer was helpful

@dukedave What I am looking for are the types of system upgrades like the ones put out by DosDude that allow system upgrades on unsupported Macs. There are many for the MacBook Pros, Mac Pros and iMacs, but I am looking for ones for the MacBook. I've successfully upgraded many of these machines.
@mayer - I don't think you can use a DosDude like patcher as this series is not 64bit clean.
@dukedave - Apple's EFI was only 32bit in the earlier systems. Thats independent of the CPU as you noted the MacBook Pro model uses the same CPU yet it supports newer OS-X releases.
@danj Thats a good point Dan, however based on the spec sheet for his computer on everymac.com, his model does come with a 64 bit EFI architecture.
@dukedave - From EveryMac:
*This system can run the last version of OS X 10.7 "Lion." It is not supported booting into 64-bit mode when running Mac OS X 10.6 "Snow Leopard."
The clue is - 64-bit mode when running Mac OS X 10.6
That tells me its the logic board logic is 32bit i.e. EFI (BIOS)

El Capitan can run on these A1181s, but they're only supported for the 2009-2011 A1181s (MacBook 5,2).
It's a shame that the 5,2s are quite hard to find (in my experience). I still use a 2007 A1181 and that keyboard is a joy to type on, a far cry from the god awful butterfly keyboards.
