New motherboard (M42A) in repaired MacBook 2.0ghz?

My fiancee just sent her MacBook 2.0Ghz, purchased about two months ago, in due to a sudden and total failure... screen went black, no response to any of the usual diagnostic and recovery tricks. She shipped it in, and the repair ticket came back reporting that they'd replaced the motherboard. At least, after years of reading service-ese, that's what I gleaned... just listed an Apple part number that didn't turn up in any good searched, PCBA (printed circuit board assembly), M42A. Nosing around, this means they replaced the motherboard (they also listed replacing the heat sink, which would make sense if they put a new MB in and kept the old Core2Duo CPU).
What weirded me out was that the symptoms (sudden total failure, no response to power switch or anything else) made me think it was a failure in the power supply, but they didn't replace the internal power controller (I know this because the MagSafe connector still had the crud on it it had when it left here).
Anyway, I have to ask: even this late in the MacBook game, are machines still being produced with early motherboards, and would they still be in the channel even now that they have the 2.16ghz units out? We bought this out of stock at CompUSA in late March, seems like the MB would have been out long enough that the problems with the early motherboards wouldn't still be visible in production units now.
What was the part number on the earliest 2.0Ghz MacBook units? And is the M42A the new, good motherboard or the old, flaky one? I get conflicting information from vendors and what little info I can pick up on the nets. Some vendors are advertising 2.0Ghz units as "new good M42A".
The unit is back in my fiancee's hands (which is cool, because her endless support questions once she was forced to go back to her Windows XP Hewlett-Packard desktop were driving her -- and me -- to suicide) and I am once again pleased with Apple's ASCs, but I was just curious about it.

Hi turtle,
Apple as other pc maker are required to have part stocked for several years after they discontinued their product, so I guess they still producing the same motherboard.
Maybe they have slightly changed here and there to patch the imperfect design but not totally changed everything around, maybe they just upgrade the firmware on the new motherboard.
Good Luck.

Time Machine error message after new motherboard installed

Hi folks,
I just had a new motherboard installed on my MacBook Pro, and now whenever Time Machine tries to do a back-up (on the same external drive I'd used previously for Time Machine), I get an error message that says there isn't enough space.
It appears that the attempted back-up tries to back up the entire internal MacBook drive (rather than just the latest updates).
In other words, since the external drive already has the old data on it, attempts at back up fail.
Is there something I need to update? Or, do I need to delete all the data on the external (i.e. Time Machine) drive and let the system do a complete back-up?
Any advice would be greatly appreciated. Thanks very much.
Vic

You could try the procedure in the article linked below, but I recommend that you first start a new TM backup on another drive. You need more than one backup anyway. I haven't tested the procedure myself and I can't promise that it won't destroy your backup set, even if you do it right.

New Motherboard + trouble existing CS6

I recently needed a new motherboard in my apple macbook pro and now each time I open a program of my earlier purchased CS6 Design & Web Premium I get a pop up window that I am in a Adobe trial version and that I can license a creative cloud.
I do not want that. All I want is to continue with the earlier bought software.
What can I do to get rid of the pop up and that I can easily continue to use my CS6?

My motherboard died on hp laptop. i put my hard drive into an enclosure to access data. is it possible/how do i transfer my bookmarks from hard drive to my new computer which is a macbook pro?

hello. my name is brandon. my hp laptop motherboard died 3 days ago. i have put my hard drive into an enclosure to be able to access all my info and files. i have successfully transferred all my files, but I am not sure if, or how i can access all my mozilla bookmarks from my my old hard drive to be able to put onto my new laptop, which is an macbook pro. my bookmarks were crucial to pay bills etc, so any help would be greatly appreciated, brandon

Not familiar with the Mac file structure either but you can transfer the entire content of your Firefox profile replacing entire content of a firefox profile you created on new HD. For me copying over a few files was out of the question all of the files are updated and I wasn't about to reinstall 150+ extensions and set up configurations for everything and to do that for that 20 profiles and .ini file. Except for 3 most didn't have a lot of extensions but it would be rather impossible.
I copied everything from the Mozilla folder down in the user libraries so all my profiles were set, it did something similar for application libraries.

New refurb MacBook 2.0Ghz Intel Core 2 Duo shutting down...help!

Refurbished MacBook 2.0Ghz Intel Core 2 Duo, White 1GB RAM, combo arrived yesterday. Running Jaguar. Ran fine out of the box on battery power for about 3 hours till the battery ran out when it shut itself down. Now its shutting off with the button gently pulsing, every few seconds. Won't stay up long enough to get at system prefs or anything else for that matter. One very disappointed 10 year old in our house. Any known issues or fixes? Thanks

Are you sure its running Jaguar? Maybe you meant leopard?
Have you charged the battery already? Try to connect the power adapter and see if that allows you to turn on the computer longer. If the same issue persists, reset the SMC following these steps:

They both have seemed to have happened when I unplugged the mini-DVI cable while the Macbook was asleep; upon unplugging it and waking the Macbook, the screen was light-bluish and the computer was unresponsive. After I restarted using the power button, I noticed the panic.
I have attempted to replicate the problem numerous times to no avail. Called Apple Care and they were of no help (told me to reset the PMU). I haven't had the problem since the 10.4.7 update, so am hoping it fixed the issue?
Macbook 2.0ghz Mac OS X (10.4.7)

There isn't much there that points to a direct cause, but the unloaded kext was for USB, so do you have any third-party USB devices connected? If you do then disconnect them to see if it helps. If not then I would consider running the hardware diagnostics to see if there is a hardware cause.
How to run hardware diagnostics for an Intel Mac
Boot from your original OS X Installer Disc One that came with your computer. After the chime press and hold down the "D" key until the diagnostic screen appears. Run the extended tests for a minimum of two or three hours. If any error messages appear note them down as you will need to report them to the service tech when you take the computer in for repair.
Some "common" error indicators:
SNS - sensor error
MEM - memory error
HDD - hard disk drive error
MOT - fan error
Newer models no longer require the installer disc to run diagnostics. But the rest of the procedure is the same.

Start-up stumbles with new motherboard, 10.5.5

The motherboard of my MacBook Pro recently died. It came back with a new motherboard and loaded with 10.5.5. Since then, the machine has balked on start-up. Sometimes, I get the tones, then a gray screen, then a freeze. On other occasions, it tries to start, gives up, goes black, and tries it again. It happens over and over. The machine never gets beyond a the apple screen. Eventually, I have to drop the battery to make the cycling stop. And then, there are those times when I get the black "curtain" dropping and a message in several languages that I have to restart. No kidding. I have managed to get it started on several occasions by blowing the P-RAM and cursing a lot. Once It is going, I use Onyx to try and keep it going.
Below is the message I got after one of those forced restarts:

Welcome to the Apple boards:
Without question I would return the computer to Apple for re-repair.
There could be another bad component, a bad connection or cable. You should not spend any time diagnosing what is most likely a hardware problem that you cannot easily fix anyway and doing so might void the warranty.
Panics are usually caused by bad RAM.
You might unplug and replug your RAM module(s) - the socket may be dirty - but even there be very careful. Beyond the RAM, I don't think there is much for you do to.

Ill not boot. just had new motherboard (or whatever mac call it) and RAM fitted and still U/s

17inch Macbook pro has just had new motherboard (or whatever mac call it) fitted and RAM replaced at great expense and still useless. Will not boot. tried booting in safe - with shift held - no joy. Any suggestions?

Your solution lies with who ever repaired the MBP. Based on what you are describing, the repair is unsatisfactory so bring it back.
Ciao.

I need a new inverter cable for my MacBook (5.5 years old). Can I get it replaced cheaply, or should I buy a new laptop?

Hi! I have a 5.5-year-old Macbook4.1, and I've been having problems with the display. I googled the problem and found out that I've got a wonky inverter cable. Apparently, the part itself is relatively cheap, but the labor (which involves taking nearly the whole laptop apart) means that the repair is expensive. The quote I got (in Germany, where I live) is 200 euros.
My laptop has been functioning just fine besides the display problem, but since it's already so old, it seems to make sense to buy a new laptop rather than repairing this one. However, someone told me that I should contact Apple first and see if they might cut me a deal on the repair, since I'm an existing customer and they'd want to keep me happy. I tried doing this through the Apple Support site, but I'd have to pay $50 to do that, which seems to defeat the purpose. Going to an Apple store is also prohibitively expensive, since there aren't any very close to me.
So my question is this. Does anyone see any reason why I shouldn't buy a new laptop? The one I would probably end up buying is about $550 (not a Mac), so it's more money than I'd pay for the repair, but...you know. Sunk costs, and all that. I'd be appreciative of any opinions!
Sidenote: in case anyone doubts my diagnosis, here's a description of the problem. When my screen is open, I can see a very faint picture on the display, but the screen is pretty much dark. When I slowly tilt the screen as if to close it, the picture suddenly comes back. So when the laptop is open at any angle more than about 45 degrees, the display is dark.

go on give it a go! what have you got to lose;

Windows PC User Making The Big Switch To Mac OS X & MacBook 2.0GHz

I'm from the Philippines. I've been a Windows PC user for around 10 years. I figured it's time to replace my old Pentium III 500MHz/Win98SE with a newer system to keep up with highter system requirements set forth by newer applications.
The features I looked for include portability, performance, connectivity (built-in WiFi & Bluetooth) and value (not too expensive). I'm initially leaning towards getting another Windows XP-based platform because Windows-based apps are readily available here and getting tech support for the Mac would be a little prob. Also, I just can't afford to leave behind some applications that are somehoew inexistent in the Mac world, but the mere thought that the PC world would soon be shifting to Vista kinda turned me off. Nobody wants to buy a new notebook that would suddenly become obsolete in just a few months or so.
However, everything changed when online research led me to Apple's homepage (www.apple.com), where I discovered Mac's latest wonder: the Macbook. I heared about the Mac OS X's reputation for stability and performance. They say Macs are less prone to worms & viruses too since most of these things were designed specificically to infect Windows-based platforms. Looks like this is it for me. I'll be getting a MacBook 2.0GHz soon.
I must admit that what primarily attracted me to the Intel-powered Macbook is the fact that it could now run two operating systems thru "Boot Camp" or Parallels For Mac. Two applications that would give me the capability to run Mac OS X and Windows XP on a single platform. It's like having the best of both worlds.
For me, this is really great news but I still have questions though. The Macbook is a new release, so I'm still iffy about purchasing it as new technology is notorious for having many annoying quirks and kinks that need to be smoothed out.
My question is... What are the PROS and CONS of using BootCamp and Parallels respectively? Is Parallels better than the other? Which one would you recommend? Should I decide to install both, will there be any hitches?
I won't be upgrading for the next 5 years or so. The notebook will likely see some heavy use for Medical Transcription work and maybe occasional gaming (mostly flight sims). This would be my first Mac purchase so I better do it right the first time. So if you have any comments, feedbacks, suggestions... kindly post it here.
I'll be making the big switch soon.
Rich

I'm running Parallels on an iMac 2.0 GHz, and I absolutely love it! I expected all sorts of glitches and found virtually none. The only drawback I know if is that it treats your USB 2.0 ports like USB 1.1. Otherwise, my Windows XP virtual machine inside of Parallels doesn't seem to know it's not on a PC; it runs smoothly and much faster than on my previous 1.5GHz PC with 1.0 GB RAM. I've loaded Quicken for Windows, MS Office, Norton Anti-Virus, Adobe Acrobat, and several other Windows Apps with no troubles at all. I'm telling you, this software (Parallels) is amazing. I feel like I literally have two computers now.
I would recommend that you have 2.0 GB of RAM, because while you're running Parallels, you have 2 OS's operating at the same time. But the ability to switch back and forth between the two OS's, share files, cut and paste - well, it's simply awesome, and well worth any extra cost.

How can i get a new motherboard?

I have an iMac and it doesn't work!
My technical advisor said, it needs a new motherboard.
Anyone who knows how can I get one from Apple Store?
(I couldn't see this option on the website)

You cannot order a motherboard or any such parts from Apple. You'll need to take your iMac to an Apple Store or authorized Apple service center for repair. You can search the web for independent parts providers if you want to do the repair yourself, though that will void your warranty should your Mac have any remaining.

How can I use new apps on an old macbook?

Hi all.
I've been using macs since September now, and there are a number of things I've found infuriating about working on my Macbook...
My Macbook is an old, mid 2007 model, Version 10.6.8, with a 2.16Ghz Intel Core 2 Duo Processor and 4GB.
Unfortunately, this model of Macbook will not update to any later version. This means there are a lot of apps I cannot use on it.
I'm a filmmaking student, so editing is a huge part of my course. When downloading the newest version of any editing software (such as Premiere Pro or Avid Media Composer), the Macbook will simply refuse to install it, because it requires a newer version of OS X. This is just one example of the many things I cannot do due to the OS X version on here.
How can I get around using newer apps such as Premiere Pro with version 10.6.8? Baring in mind I'm a student so I cannot afford to spend money on a new hard drive or anything.
Also, if I have bought various games on Steam, but some of them are seemingly only playable on PC, can anyone tell me how I can get around playing those games on a Mac?
Any help is greatly appreciated.
Thank you in advance.
Steve

The Core2Duo MacBook (13-inch mid 2007) is rather dated, and to run a certain type
of software on that model you'd have to get the version which was current when the
computer model and the OS X versions it could run were prevailing. So an old version
of something you need (used, new-old-stock, etc) may do the job for a time.
Also, the Core2Duo series of early MacBook can run Lion 10.7.5 and that is about $20.
as a download with code you buy from the Apple Store online. There are a few updates
to the Lion version 10.7 once you went that far. Some older 10.6.8 capable applications
for Intel based Macs would probably still work OK in 10.7.5, but none of the PPC coded
third party applications would run without the Rosetta feature installed in Snow Leopard.
According to MacTracker database, your old Core2Duo is one of those which can run
Lion 10.7.5 at the latest, and a slight upgrade in RAM to 3GB total, is possible. Not sure
if any advantage of using two 2-GB chips would be seen as functional in there, but that
is an easy way to round off what is written as the higher supported amount of RAM. With
two of the 2 GB chips. Otherwise: one - 1 GB + one - 2 GB = 3GB lists as total.
A good repaired MacBook or MacBook Pro of earlier vintage isn't very expensive; some
companies offer the versions older than those available at the Apple Store refurbished
page, that still may be capable, yet not run the latest applications. And several of them
probably should not run Yosemite since their hardware may be marginal. Models that
cannot have their hardware upgraded to run a later OS X, should not be chanced.
Sites such as macsales.com sometimes offer used Macs, wegenermedia.com has a
few different models, since they repair computers and offer excess on their site. The
powermax company has some. Not sure who actually repairs what they sell, with an
exception to wegenermedia who does repair on-site and will accept repair orders.
The everymac.com site is helpful in comparing various build year model specifications
as is the downloadable database of update upgrade specs from http://mactracker.ca .
So, you can upgrade past Snow Leopard 10.6.8, but that may or may not break other
applications you may still be able to use from the preceding era of Mac software. Lion
also would probably prefer more RAM than SL 10.6.8, so you're max-ed out there.
The MacBook series has been discontinued for nearly 5 years (2006 to 2010) so their
last model was among the better ones. MacBook/Pro 13-inch Late 2012 remains good
since you could add RAM and possibly upgrade the hard disk drive. It's a non-retina.
Hopefully you can find a deal on some good condition later model MacBook or Pro.
Good luck & happy computing!

Installing 10.6 on a new hard drive in 13" MacBook

Last night, I dropped my (13", 2007) Macbook and damaged the hard drive beyond repair. I have no bootable back-up. I had upgraded this Macbook to 10.6 a few months ago, using the Snow Leopard Family Pack.
So now I am about to install a new hard drive in the MacBook (it's coming tomorrow.) What I am wondering is whether I will actually be able to install 10.6 on this new drive, using the Family Pack DVD. When I installed it on the Macbook earlier, I believe I did an erase and install, but I thought it required having 10.5 installed on the computer.
Any insights or advice would be welcome (other than "keep a bootable back-up" hahaha!)

You can install OS X on the new drive but first you have to prep the new drive:
Extended Hard Drive Preparation
1. Boot from your OS X Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger, Leopard or Snow Leopard.)
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID (for Intel Macs) or APM (for PPC Macs) then click on the OK button. Click on the Partition button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
Once formatting is completed you can quit DU and install OS X.

Asking for 16-digit serial number after installing new motherboard

Hi, my computer's motherboard died and I got a new one installed. I own Creative Suite 6 Design and Web Premium and it is installed on this machine. Since I got the new motherboard, if I start up an Adobe application the Adobe Application Manager pops up and asks me for a 16-digit (all numerals) serial number. But the CS6 serial number is NOT all numerals and is NOT 16 digits, so it won't let me type it in. I have no other serial number. How can I fix this? Currently my apps are still working, but I think they think they are a trial version that expires in 30 days. I'm using it on a MacBook Pro running OSX 10.9.3. Thanks.

YOu are wrong. Serial numbers are always only numbers. What you have is an eligibility code. Since you obviously already activated it a nd exchanged it for a final serial number, it must be somewhere on your account or your archived e- mails. If not, contact support directly by web chat.
