2008 Aluminum MacBook 2.4 Recv Errors Cisco Switch

Something odd I recently encountered with my wife's 2008 Aluminum MacBook. Since it was purchased several years ago, it has almost exclusively been used on wireless. This model uses the NVIDIA MCP79-1 chipset with 9400m graphics.
While waiting for some large files to transfer, I opened up Network Utility and noticed that it is showing Recv Errors between 5% and 10%. There was no issue transferring multi-GB files and there was no packet loss when an IP address on my internal LAN was ping'ed for several hours. It is almost as if Network Utility sees something bad with the packet, but the packet doesn't drop.
The MacBook is running 10.8.2 and is plugged in to a Cisco Small Business SG200-26 managed switch at Gig speed.
Things I have tried:
• New cables, shorter and longer cables. Cat5e/Cat6
• Multiple ports on the switch
• Hard coded both the switch and the Mac to 100Mbps Full Duplex
• Disabled all QoS and special routing (basically everything can talk to everything all on one VLAN now)
• Stole cable from my iMac and plugged in the MacBook...still has receive errors. iMac had 1.5 million packets transferred with none lost.
• Safe Boot
• Zapped PRAM and reset SMC
• Enabled firewall with only key ports open (DHCP, DNS, ICMP, etc)
• Tried both enabling and disabling flow control on the switch
One thing worked, but doesn't make sense.
• Daisy chained an old Fore Systems ES2810 10/100 managed switch to the Cisco Small Business SG200-26 and plugged the MacBook into the Fore switch. The MacBook no longer shows receive errors.
None of my other Macs experience this issue (Mid 2007 iMac, 2009 Mac mini, PowerBook G3/500)
iMac is on 10.8.2, Mac mini on 10.6.8 (Rosetta support) and PowerBook G3 on 10.4.11.
I guess I'm beginning to wonder if there is some kind of broadcast traffic that the other NICs in the Macs are able to properly process. Anyone else have a strange issue with this model and certain switches?

Same thing just happened to me again. My aluminum Macbook was hibernated all morning. I took it to Starbucks for lunch, and when it came out of hibernation, the trackpad was working just fine. However, about 20-25 minutes later, while typing in a online form textbox (in Firefox), the trackpad's tap-to-click stopped working and I could not move the mouse pointer for a few seconds. I even tried to physically click on the trackpad, but that didn't work either. A few seconds later, everything started working again. It seems as though there's some kind of process running that interferes with the trackpad's operation. Or, perhaps, this has something to do with the heat factor - the trackpad stops operating when it reaches a certain temperature, and as the temperature passes that mark, it starts working again.
Please post to this thread if you have similar problems. There are reports about the same issue on Macrumors.com. At this point, Apple needs to know about this problem and should start working on addressing it. Hopefully, this is a software problem and can be corrected with a software update.
Thanks!

Late 2008 aluminum Macbook Pro (15in 2.4GHz) using 8GB of RAM

Hi everyone,
I have a quick question to ask, What I'd like to know is why the Late 2008 aluminum Macbook Pro motherboard has a chipset (Nvidia) that can support up to 8GB of RAM but Apple are stating that the system can do only 4GB?
According to NVidia, The motherboard is fully capable of using 8GB of RAM but has been limited to 4GB by Apple and that this can be resolved by a simple EFI update.
The links below show a well known Apple parts dealer running tests on the system using 8GB RAM and claims that the OS X can read it perfectly but the programs will not use more then 4GB of the RAM.
I really don't understand why Apple would limit the system to use only 4GB of RAM and if Apple have any plans on releasing an EFI update.
Thanks for reading guys

Economics 101: So if you want 8GB, you have to go buy a new MBP and pay another grand for the memory. After all, they are in the hardware business, right?

Cover/Case for 13" Late 2008 Aluminum MacBook?

I have a 13" late 2008 aluminum MacBook and am trying to find a cover/case (preferably the hard shell) that will fit it. I read that they are no longer made for this model so it will be hard to find. The websites I found that offer cases for this model were not able to say that it would be a guaranteed fit. After seeing so many reviews about how they don't fit this model, I am hoping that someone on here could direct me to a website that sells ones that will for sure fit.

Go to OWC's site,
You'll see the selections on that page. Great company. No hassle returns and great support.

Can I replace my 250Gb SATA HD in my 2008 aluminum MacBook with a new SATA3 Solid State Drive?

I would like to replace my 250Gb SATA HD in my 2008 aluminum MacBook with a 500Gb SATA3 SSD. I want to do it because of the age and to increase capacity, access speed and reliability. Is SATA3 backwards compatible to SATA? Should I save some money and just stick to a regular SATA higher capacity HD and forget about a SSD?

I replaced the hard drive in my early 2009 model with a Samsung 840 ssd. My book has the same sata interface as yours and accepted the newer drive without a hitch. It's the best $160 I've ever spent on a computer upgrade. My macbook feels like a new machine. I would highly recommend it.

2008 aluminum macbook keys stopped working

my late 2008 aluminum macbook keys suddenly stopped working, it is keys 1qaz backspace and two volume buttons. i neved spilled water on it, has this ever happen to somebody else and if so what was the problem.

This sounds like a hardware fault. Contact Apple using www.apple.com/support/contact if you are in a country that supports it or call the appropriate phone number on this page. Alternatively carry the MacBook in to an Apple retail store or service provider to ask for an estimate.
Best of luck.

MX200 won't boot 2008 Aluminum Macbook, except after PRAM reset.

Hello all, Can anyone confirm if the MX200 SSD works in a late 2008 Aluminum Macbook? I formatted and installed Yosemite 10.10.4 onto an MX200 and put it into the Macbook. I can boot the Macbook from the disk only when I zap the PRAM. Once the Macbook is running OS X, I can "Restart..." the Macbook with no problem. But if I "Shut Down..." the Macbook, I can't boot past the grey screen with the Apple logo and an empty progress bar below it. It just sits there, for hours, with no progress. Then, if I kill the Macbook and zap the PRAM, the Macbook will boot up quickly without any problems. Anyone else experiencing this? I would like to be able to shut the computer down and start it again when I please, without having to reset the PRAM everytime. Are the MX200 and the 2008 Aluminum Macbook simply not compatible in this regard?

Which imacs and apple displays connect to late 2008 aluminum macbook 13 inch for use as external display?

I have a late 2008 13 inch aluminum macbook and want to purchase an iMac computer or apple display to use as an external display for it while I'm at my desk.
I can afford up to $700 for sure, maybe up to $1000 and would like one that has built in camera and audio if possible.
I'd like to know what my options are as it seems not all are compatible.
I'll mostly be doing web browsing and photo editing in Aperture.
Also wondering if it's possible to sync 2 computers so that when you make changes on one it reflects the changes in the other. Like you can with certain apps like Evernote.
Thank you for your help!

Yes he is right, Snow Leopard is your first step. Once you have that you can upgrade directly to Mountain Lion if memory serves me correct. Some people were saying that Lion was a little sluggish with the aluminum MacBook but that Mountain Lion was great. Personally I had Lion on it also and didn't think it ran badly. 10.6 was still with Rosetta (the program that ran power pc apps) but this is dropped on 10.7 and up. Up until just the other day I still had the stock 2 gb of ram. The firmware update happens with Snow Leopard and up so it should come up as a software update. If not, it can be done manually as well. The ram I purchased was 60 bucks for the 8 gb. For Lion and Mountain Lion I have to agree with the above reply, that it would run alot better with at least 4 gb. If you run that many apps at once then you are going to want as much ram as you can get. If you add a solid state drive you will be amazed at the difference it will make too.

2008 Aluminum Macbook OSX Upgrade

Hi,
I have the first aluminum macbook that was released around December 2008 (2GHz Intel Core 2 Duo, 2GB 1067 MHz DDR3). I'm running 10.5.8 and I wanted to upgrade my osx but I wasn't sure if I should do Snow Leopard, Lion, or Mountain Lion. I'm mainly doing it because I find that I can't download and run a lot of programs (my osx is too old). However, I'm afraid that if I upgraded, it wouldn't run as smoothly because I don't have a lot of RAM. I was just wondering which osx you reccommend, if I can leave my RAM alone, and if not, how much more I would need to install. Thanks!

You're welcome. I would recommend snow leopard and upgrading your RAM to 4 GB for comfortable use. If you are a student, you are probably using MS Office, or atleast word, as well (just an assumption). I would not go beyond snow leopard. Snow leopard was a major leap forward (introduction of the App store, for example) for OSX, and your machine will have no problem running it. Lion is currently 30$ and unavailable through the App store, and Mountain Lion would slow down your machine's performance. I would see no benefit in upgrading beyond SL for your purposes. If you decide to increase your RAM as well, I recommend using OWC. They provide 1 year warranty on all modules:

My Late 2008 Aluminum MacBook keeps crashing on new OS X 10.8.1

I recently upgraded my Late 2008 Macbook to Mountain lion. Since doing so, my computer is running really slow and constantly crashes. I cant have more than two programs running at the same time, otherwise the computer will freeze up and i get the "rainbow pinwheel of Death". I also experience issues with my internet crashing as well as quicktime player issues.
Please help me if you can. I am Seriusly thinking about finding a way to go back to lion, cause i never had an issue before!

While we all have MacBooks in this forum most of us don’t run Mountain Lion. There's a Mountain Lion Support Community where everybody has Mountain Lion. You should also post this question there to increase your chances of getting an answer. https://discussions.apple.com/community/mac_os/os_x_mountain_lion

Why did my ethernet stop working on 2008 Aluminum MacBook after upgrading to Mavericks?

At home (using an AirPort Extreme) my ethernet works, but anywhere else I go it will not recognize. I have tried manually setting the IP and removing, adding the ethernet connection. No matter what I do it still says "Not Connected" it states that either the cable is unplugged (which it isn't) or the connected device isn't responding. I am assuming it is a driver/firmware issue in Mavericks that doesn't support the DHCP discovery. Can someone please shed some light on the situation?

I already did that and still nothing. My 2012 Retina MacBook Pro running Mavericks works fine, so I am confused as to what is causing this on the 2008 MacBook.

Late 2008 Aluminum Macbook is starting to give me trouble.

Issue #1: Sometimes, when I'm typing something, the cursor will just randomly select another position to go to unexpectdly, and I would have to correct that error and then move the cursor back to where I was typing before.
Issue #2: Lately, whenever I'm watching videos on YouTube, my computer will temporarly freeze and then give up a flicker (like the screen itself is beginning to fail). After the flicker I can move the mouse for a brief second or two until it repeats the same process and I am forced to shut down the computer.
Does anyone have any ideas on how to correct either one of these problems that I'm facing?

Just to be clear, there's drives, and there's the enclosures holding the drives. I don't know that Iomega actually makes drives. They are probably like many other backup drive vendors who make an enclosure, then buy drives from Seagate or Western Digital or Toshiba and put them in their enclosure. I opened a LaCie "drive" recently and found a Western Digital hard drive inside.
I usually don't buy a drive package, or if I do I make sure I get one with a known good brand drive inside a known good brand enclosure. You might want to check what www.macsales.com has.
Of course the OP may be some issue that isn't really related to the drive quality but some other issue such as drive corruption which andy quality drive can have.

Late 2008 aluminum MacBook running extremely slow to the point where I can't open or close applications/windows. What is wrong with it?

It was working just fine. I had just downloaded a 130 mb album. A few minutes after my MacBook basically stopped working. I could not open applications or close them. I decided to restart my computer and this did not help. I am able to turn my computer on and off but that is it.

Boot in Safe Mode so you can see how much free space there is on the startup disk.
Startup your Mac in Safe Mode
A Safe Mode boot takes longer than a normal boot so be patient.
Once you are in Safe Mode, click your Apple menu icon top left in your screen. From the drop down menu click About This Mac > More Info > Storage
Make sure there's at least 15% free disk space.
If there's less than 15% available disk space, you need to delete files to free up space. You can do that in Safe Mode.
Then click Restart from your Apple menu .

I have 2008 aluminum macbook with OS X Lion. It does not recognize my canon sd1000. Finder does not show the camera.

My macbook does not recognize Canon SD1000. Camera goes to transfer mode and it looks like the problem is the computer. Finder do not show the camera at all. (I am not using any programs, iphoto etc...).

Instead GarageBand recognize my keyboard and i can play normally, also, if it can help, those are the Audio and Midi Logic Preferences and the Controller Surfaces Setup with the keyboard connected :

7 u j m keys not working after 10.8.1 upgrade, late 2008 aluminum Macbook

That's all, these keys do not work after update/upgrade today. They were working fine right before i did the update and are not working now. If I hit the M ket a few times i do get some garbage. Help?

Thanks, but still the same. It boot normally only if there isn't any usb device attach to the computer. I'm using usb mouse instead of bluetooth mouse and it happens not to boot normally like usual.
The technician said it would be okay if any usb devices attach to the computer during the boot apparently it won't boot normally.
Any alternative sir?
