Can Macbook 4,1 (early 2008) 2.4 GHz Intel Core 2 Duo be upgraded to Mountain Lion?

I just upgraded to 4GB of memory after reading somewhere that the Macbook Model Identifier "4,1" can be upgraded to Mountain Lion. I was surprised to read under 'how to upgrade to Mountain Lion' that Macbook's (Late 2008) are upgradable. Aside from this upgrade being less expensive than buying a new Mac, my current Macbook runs perfectly after five years, or I wouldn't be considering an upgrade to the OS. I've been told that Snow Leopard is the last truly solid OS from Apple, and I just got an iPhone 5 that would be more compatible with Mountain Lion. Final note, the site that stated "4,1" is upgradable also stated that while Apple states maximum memory is 4GB, that in fact it can be maxed out at 6GB. Optimistic until advised otherwise.
Any input is much appreciated.
Thanks.

Welcome to the Apple Support Communities
OS X Mountain Lion requires a Late 2008 Aluminum or Early 2009 MacBook or later, so you can't install Mountain Lion in your Mac. Read > http://www.apple.com/osx/specs
It doesn't mind that your computer is useless, because Snow Leopard is still supported and Apple updates Snow Leopard, so if you are happy with Snow Leopard, continue using that version. A lot of people say that Lion doesn't work properly with old computers, but Mountain Lion fixed most of its issues. Apart from that, the iPhone 5 is compatible with Snow Leopard in the same way as with Mountain Lion, so don't worry about that

Have MacBook Pro (ancient) has 2.16 Ghz Intel Core Duo with 1 GB 667 MHz RAM using OS 10.4.11. Can I upgrade OS? If so, how far? And can I add more memory? I realize this is an old laptop but I need to wait to upgrade to new.

iOS 5 is for iDevices, not OS X. Your iDevice would only require 10.5.8 or later. If you have a Mac with a Core Duo processor then you cannot install Lion but you can install Snow Leopard provided you have at least 1 GB of RAM installed.

My thanks to you and all other respondents. In backing up "theVault" App I thought that my ancient version of Stuffit was inadequate to unzip the backup file. I attempted to download the latest Zipit version which only works with Lion. After upgrading to Stuffit 9 I realized that theVault backup file was encrypted so as to not open on the backup Mac. One must restore to the iPhone where is does open.
My apologies for the imprecise post. I am finding limitations with not being able to install Lion on my early MacBook Pro. I can recommend theVault to those looking for a password App with secure backup.

Is installation on 2.16 GHz Intel Core Duo (MacBook Pro)really not possible and why?

I would like to buy OS X Lion and install it on my MacBook Pro with 2.16 GHz Intel Core Duo, but this processor is not in the list of the specifications (Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7 or Xeon processor).
Is it really true that I can't install Lion on my Mac? If so, what is the reason?

It has to be a Core 2 Duo. Those are the requirements for Lion.
Requires a newer Mac.
Lion requires an Intel-based Mac with a Core 2 Duo, i3, i5, i7 or Xeon processor and 2GB of RAM.

Open the Mac App Store and try downloading Yosemite. If you get told it's incompatible, choose About this Mac from the Apple menu, check if the computer has at least a Xeon or Core 2 Duo(not Core Duo) CPU and 2GB of RAM, and if it does, click here and order a download code for Lion 10.7.
Back up your data and check your applications for compatibility before upgrading. In particular, Mac OS X 10.7 and newer don't support PowerPC programs such as versions of Microsoft Office prior to 2008.

I am running 10.6.8 but can't upgrade to Lion. 1.83 GHz Intel Core Duo processor 1.83 GB memory. What should I do?

My MacBook software is 10.6.8 but I can't upgrade to Lion. 1.83 GHz Intel Core Duo with 2GB memory. What to do?

Lion/101.7 System requirements
    •    x86-64 processor (Macs with an Intel Core 2 Duo, Intel Core i3, Intel Core i5, Intel Core i7, or Xeon processor.)
    •    At least 2GB of memory, (I say 4GB)
    •    Latest version of Mac OS X Snow Leopard (10.6.8), with the Mac App Store installed
    •    At least 4GB of disk space for downloading, (I say 40GB at least)
Like Snow Leopard, Lion does not support PowerPC-based Macs (e.g., Power Macs, PowerBooks, iBooks, iMacs (G3-G5), eMacs).
Lion also does not support 32-bit Intel Core Duo or Core Solo based Macs. Rosetta is no longer available in Lion, which means Lion no longer supports PowerPC applications.

Please describe the problem in as much relevant detail as possible. The "etrecheck" fad hasn't made that step any less necessary. The usual results of posting etrecheck output on this site without a full description of the problem are very poor.
The many "failed" warnings that etrecheck sometimes spews mean nothing. Those warnings are not a reason to reinstall the OS, or to do anything else at all. They should be ignored.
The better your description of the problem, the better the chance of a solution.
For example, if the computer is slow, which specific actions are slow? Is it slow all the time, or only sometimes? What changes did you make, if any, just before it became slow? Have you seen any alerts or error messages? Have you done anything to try to fix it? Most importantly, do you have a current backup of all data? If the answer to the last question is "no," back up now. Ask if you need guidance. Do nothing else until you have a backup.

I have a mac book pro, 2006 with an 2.16 GHz Intel Core Duo processor, can I update to Lion? to use icloud.

Apple keep telling me I need to update to icloud but I'm not sure if Lion will work on my Mac. I've upgraded to snow leopard which seems to have knackered my .me or .mac account (whatever it's called now), so I don't seem to have any option but to upgrade to Lion if I every want to see my emails again.
Apple say I must have a Intel Core 2 processor for Lion to work...... at least I think that's what they say.
I have a mac book pro, 2006 with an 2.16 GHz Intel Core Duo processor, can I update to Lion?

Lion System Requirements
Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7, or Xeon processor
2GB of memory
OS X v10.6.6 or later (v10.6.8 recommended)
7GB of available space
Some features require an Apple ID; terms apply.
If you have a Core Duo model then you cannot upgrade to Lion. You can upgrade to Snow Leopard, but iCloud is not available for Snow Leopard.
Open System Profiler in the Utilities folder. Look for the Model ID in the displayed information. If you have a MacBookPro 2,1 or later then you have a Core 2 Duo model and can upgrade to Lion.

It's wrong for you to assume that they don't care about what they are about to lose, even if it's one PPC program.
It's not uncommon for people to keep their software up to date.
It's wrong for you to assume that all software is being updated or that there are Intel versions available.
I have a mid/late-2007 MacBook Pro 3.1 with 6 Gigs of RAM and a 750 Gig 7200rpm hybrid hard drive that is running Mountain Lion just fine. Performance benchmarks with Geekbench are equal between SL and ML, and the Mac runs about 20 F degrees cooler than it did with SL.
You took extremely good care of your almost 7 year old machine and judiciously used it, you added more RAM and a faster cooler hybrid drive to make up for the more feature rich yet slower performing Mountain Lion.
Congratulations, your a conservative.
It would be nice to have some empathy for the people you advise that they also also don't get suddenly ambused by a OS X upgrade that's going to disable software they care about using still.
