Late 2008 Macbook -  10.8.5 software update - NO WIRELESS!

Hi, I'm throwing a fit. I updated to the 10.8.5 software a few days ago and it KILLED my wifi. I took my late 2008 macbook to Apple where they reinstalled the operating system. I mentioned to them that there are discussions on here about other users having their wifi killed after updating, specific to the late 2008 macbooks. The folks over at Apple clearly didn't like me telling them that. Anywho, they reinstalled the OS and it STILL doesn't work. They claim I need a new airport extreme? ***?
WHY? After I update my software and WIFI doesn't work, now I'm stuck? DID THE ENGINEERS IN CUPERTINO FORGOT TO TEST THE SOFTWARE UPDATE ON MACBOOK 2008 MODELS?
Why doesn't Apple have an official Facebook or Twitter? Oh right, so people like me can't publically complain?
Has anyone else brought their macbooks to Apple for this nonsense and actually had them fix it?

Hi all,
I have a fix!
just got off the phone with tier 2 apple tech support.
I have a mackbook 2008 and when I upgraded to 10.8.5 my wifi was completely broken.
Went through all of the typical reset PRAM, remove battery...etc.
Here is the fix:
Go to network prefs
remove the existing wifi configuration
     select wifi
     select the - (minus sign) at the bottom left of the window.
Select Shut Down from the Apple menu.
Restart the computer.
Open Network prefs and select the + (Plus sign) at the bottom left of the window
For me, WIfi connection was populated already.
Select Create
Go to the menu bar and you should now see all of your typical networks displayed.
Select your network.
Waallla! Sanity restored and your Macbook is back in action.
Have a great day!!

    How long do you leave it?
    Mine can sometimes sit for quite a while (maybe 10 minutes??) before it finally finishes.
    You could look at the relevant logs via Console (Utilities folder) to see if Software Update is complaining about anything.

  • I have a late 2008 Macbook Pro last updated to Mavericks OS.  The screen died and it's not worth replacing.  How do I remove the hard drive and use a drive sled to access info I need?

    I have a late 2008 Macbook Pro last updated to the Mavericks OS.  The screen died and I took it into an Apple store and was told replacing the screen and the hardware to repair everything would cost almost as much as buying a new laptop or a cheaper model.  I was told that I can use a drive sled to access data I need on my hard drive. How do I remove my hard drive and use a drive sled to get to the information I need?  What makes matters more complicated is I need to update my iPhone and my iTunes/App store purchases.  How can I accomplish this?
    My wife has a late 2008 Macbook Pro as well, which I am assuming I need to run my hard drive.  Is there a way to just access just my hard drive without interfering with hers?
    I know this is lengthy.  Thanks to whoever looks at this and offers advice/instruction.

    the device you need is an External enclosure for a 2.5" (laptop form factor) SATA drive.
    A USB-interface enclosure will be slow, but is adequate for this task and for re-purposing as a backup drive later.  A firewire-interface drive would be faster, but is harder to find, more expensive, and faster than needed for this purpose.
    The drive will mount as an "extra" drive on your wife's Macbook, and you can drag and drop whatever you wish. You could create a separate Account for yourself on her computer, and use Migration Assistant or just copy your stuff over to the new account. Then it would not interfere with her files.

  • How to update graphics card drivers for late 2008 macbook pro with Nvidia 9600m GT?

    Can anybody help me update the drivers for my 9600m GT graphics card for my Late 2008 Macbook pro? I am running OS X Lion 10.7.5 with a Windows 7 partition. I have tried finding support on Nvidia's website, but at least for the 9600m GT, it isn't supported for my operating system. Would I have to update it from my Windows side? And if so, would the update apply to my OS X side as well? I have a little computer knowledge, but nothing indepth.

    Welcome to Apple Support Communities
    In OS X, Apple provides the GPU drivers and you cannot update them from NVIDIA. They are updated with each OS X update, so you are running the most recent drivers for your OS X version. OS X Mountain Lion and Mavericks have got more recent GPU drivers, but it's not worth upgrading unless you need newer drivers for an app (I highly doubt this).
    However, you can update the GPU drivers in Windows, and you should do it to get the best performance. You can download them from the NVIDIA site > http://www.nvidia.com/Download/index.aspx?lang=en-us Note that drivers are only applied in the operating system you are installing them, so they will not be installed in OS X

  • I have bought a 2nd hand late 2008 macbook air and can't install iPhoto as it requires update 10.9 or higher i can't seem to update any further than 10.7.5 help???

    I have bought a 2nd hand late 2008 macbook air and can't install iPhoto as it says it requires update 10.9 or higher i can't seem to update any further than 10.7.5 can anyone help please???

    Thankyou for your response... being new to this i have had a look and it says the following
    This system can run the last version of OS X 10.8 "Mountain Lion" as well as the current version of OS X 10.9 "Mavericks," but does not support the AirDrop, AirPlay Mirroring, or Power Nap features. It is not supported booting into 64-bit mode when running Mac OS X 10.6 "Snow Leopard." It does support "OpenCL" and Grand Central Dispatch introduced with Mac OS X 10.6 "Snow Leopard."
    Please note that OS X "Lion" 10.7 and subsequent versions of OS X, like Mountain Lion and Mavericks, are not capable of running Mac OS X apps originally written for the PowerPC processor as these operating systems do not support the "Rosetta" environment. To run PowerPC applications on this Mac, it will be necessary to use Mac OS X 10.6 "Snow Leopard" or earlier
    what do i do next
    Thankyou once again for your reply

  • Just updated from a late 2008 Macbook Pro and I am getting a blink on my external screen

    I just upgraded from a late 2008 Macbook Pro with a  AMD Radeon HD 6770M 1024 MB graphics card and I am now getting a blink (black screen) every few seconds.
    Anyone know a fix.
    Thanks

    You could always give it a shot - the only problem that you might run into is that the the early 2011 might not boot when the hard drive is swapped from the 2008 hard drive. Some versions of OS X are simply not compatible between different models.
    But it's worth a try...

  • Late 2008 Macbook Freezes 5 Minutes into use with newly upgraded Mavericks, works on safe mode; help troubleshooting?

    Hi, I have a late 2008 Macbook - I upgraded it from Leopard to Snow Leopard a year ago and things ran relatively smoothly. A friend suggested I try Mavericks after I have been getting a few error messages with snow leopard and was forced to hard restart. I upgraded to Mavericks last night - the installation went smoothly, however Macbook has since begun freezing every time I am using it for more than 5 minutes. I checked some other discussion forums and I wasn't having the same problems as others - Chrome is updated; I don't use Apple Mail; don't have a lot of third party software (I think). I downloaded EtreCheck and ran on both safe mode and normal mode - things seemed relatively normal except I hadn't backed up my time machine (woops). I saw that Sophos was running a lot on start up - I don't use it so I uninstalled it using the developers instructions (Library/Sophos/Uninstall_Sophos) and than trashed the Launch Daemons that were com.sophos...
    So far nothing has solved my problem. My macbook will start in both modes - but only functions in safe mode. It will run smoothly in normal mode for 5 minutes or so - and I am honestly not sure what triggers the freeze. I copied numerous log files to see if someone could help identify the problem (they run through 2 hard shut downs and finally a restart in safe mode) as well as the safe mode EtreCheck report. I can get a non-safe mode EtreCheck if that will be helpful, just let me know.
    Anyone have any advice on what my problem is? Thanks!

    Hi Carolyn,
    Went through step 1 - macbook froze. Went through the second internet plugins trashing - and it froze. It's almost as if it begins processing super slow at some point and then the cursor goes beach ball and eventually I can't do anything. I did another EtraCheck run when I had it started in normal after I erased the internet plugins and I also have the log files that start exactly when it froze up again. See Below:

  • Airplay/Airparrot on Late 2008 Macbook pro with Yosemite

    Hi all,
    I am going to update my Late 2008 MacBook with Yosemite and for that purpose I am going to upgrade my laptop memory to 8GB.
    Nevertheless, I read that it is not sufficient to upgrade the OS in order to use Airplay with the Apple TV (that I am going to buy as well), but a newer hardware is required. On the other hand, there is Airparrot which seems to work with older hardware, but at the Apple store they told me that it that you lose quality and that it is not comparable with Airplay, which is much more better. So, I get a bit doubtful about Airparrot... Any suggestion/experience on that?
    Many thanks,
    /Ubaldo

    Airparrot is 3rd party program, that attempts to mimic AirPlay mirroring via software solution. Results will vary, there is a trial that can be used before purchasing. The newer hardware is required for native mirroring as it uses the newer processor to do video encoding.

  • Late 2008 Macbook shut-down installation pop up

    Lately when I shut down my late-2008 Macbook a pop-up asks "Continue the Installation?" and it gives me the option to "Abort" or "Yes". How do I find out what program this is for? The pop up does not give any information as to what program this is for.
    I do not click any of the options, and the pop up quickly disappears and my Macbook continues to shut down without issue.
    I just want to know how to find out which program is trying to be installed.

    You will find out if you click on "Yes." Whatever it is it's for software you have decided to set for automatic update or you started an installation already but never finished it. Perhaps a firmware update or an OS X update, for example.

  • I have a late 2008 Macbook Pro, I am trying to run MW3 but it will not work without crashing a few minuets into the game. The general specs on my computer are a dual processor 2.53 ghz. 4 gb ram and a NVIDIA geforce 9400 (9600 is the alternate card)

    I have a late 2008 Macbook Pro, I am trying to run MW3 but it will not work without crashing a few minuets into the game. The general specs on my computer are a dual processor 2.53 ghz. 4 gb ram and a NVIDIA geforce 9400 (9600 is the alternate card).
    Things to note:
    I have been unable to update firmware on this computer for about a year now. Im not sure why.
    I am running a bootleg copy of Windows XP on this computer, I would not like to spend $149 to get Windows 7 if possible.
    any thoughts on the matter would be greatly appreciated, thank you.

    Why don't you take your 'old' MBP into your local Apple Store and have them check out everything that's wrong with it - and I mean everything? Then, when you get an estimate about how much it would cost to get the machine completely repaired, ask about the Apple flat-rate repair pricing?
    It's worth a shot - and with what you may save, you can put in the bank for a new MBP.

  • Renewing a Late 2008 MacBook Pro: hard drive and battery substitution

    Hi all,
    I am an happy user of a late 2008 MacBook pro.
    However, with the passing of time, it became slow and the battery also deteriorate (it still quite OK, but it is not like at the beginning).
    But let's start from the beginning: the hard drive
    By googling for a while, I noticed that several people experienced very slow performance of their late 2008 MacBook Pro. That is also my case. Apparently, this is due to the hard disk which is dying, and then I considering to change it. However, I haven't found answers to these questions:
    - Is it possible to mirror all the containt of the current disk to the new one?
    - I only have the original installation disks of the first Leopard. I made all the updates through the network. Moreover, since it passed lot of time, I am afraid that some sector of the installation disks may be damaged. This means that I may fail in the installation of Mac Os X on the new hard drive. If I have to reinstall everything from scratch with the new hard drive and without installation disks, how should I do?
    - If I go a Mac Reseller shop, will do they perform this operation? And how much does it costs to make it? Or I may also go to some generic computer reparation guy?
    - Is it convenient to save all the data (movies, documents, pictures, emails, etc) somewhere (e.g. external HD) and then perform a completely new installation?
    Next, let's consider the battery.
    Here is a screenshot taken with iStat Pro:
    Do you think it is worth changing it? From System Profile I have those other info:
      Full charge capacity (mAh):          3386
           Current (mA):          846
           Voltage (mV):          12029
      Condition:          Replace soon
    What do you suggest to do then? How much does it cost a new battery? Actually, I think that also the processor performance deteriorate (it often becomes very hot, especially when watching Flash or Silverlight stuff), but, unfortunately I cannot change it.

    Hi!
    Thanks for all the answer. Please let me to resume this old and interesting discussion.
    After having evaluated several solutions (including NAS, different ways of backup, etc) I bought an external firewire HDD, since I believe it nicely fits my necessities. Next, after these holidays, I will finally replace my old HDD with a SSD one. I think 120 GB are ok. I just need the apps and small-sized documents (rather LaTeX, Matlab, word, pages or excel documents, etc. - no movies or mp3 (I have Spotify, for that) ). Large files (e.g. movies, pictures, etc) may end up in external firewire HDD.
    Now, let's consider the OS. I currently have 10.6.8 and I am very satisfied of that. I find it very stable, and all the apps I need are still well supported. On the other hand, given that there are like 5 years that I have the same installation, I may have a lot of obsolete files and setting that I can safely remove. This means that once I will have performed a backup of my documents, my email, my pictures etc. I can safely throw away all the rest. Hence, I may perform a brand-new installation of the OS. Although I am happy with 10.6.8, I was wondering if it is worth to upgrade it (I have a 2.53 Ghz Intel Core 2 Duo - 4 GB 1067 Mhz DDR3 RAM) to Lion, Mountain Lion or Mavricks. In that case, which would be the real benefits? And what about the cons?
    Finally consider that I only have the Leopard installation disks from 2008 (not even Snow Leopard) and I will bring my laptop to a techician to change the HDD (I know, it is simple but I don't have all the screws etc. and I will not buy them only for this purpose). Once he will have replaced the HDD, will he re-install the OS also? Or I have to reinstall the OS through my original DVD (5 years old, I don't even know if they still work) and upgrade to Snow Leopard again by myself? I would exclude the carbon copy solution since I may want to throw away a lot of garbage and perform a brand new instalation of the OS. How to proceed? Thanks again!

  • How do I install Mavericks onto a new SSD HD in my late 2008 MacBook Pro?

    How do I install Mavericks onto a new SSD HD in my late 2008 Macbook Pro, and then I  hopefully can reinstall my data from my Time Machine backup?
    I presume the SSD will need some type of formatting, before I can install Mavericks from the internet? Then can I use my Time Machine backup to reinstall all my other software and settings?

  • Replacement hard drive for late 2008 Macbook Pro

    I need to replace my drive in a late 2008 Macbook Pro 15".  I can access the battery and what looks like the hard drive from the underside, if this helps.  Would this be a good replacement choice?
    http://www.newegg.com/Product/Product.aspx?Item=N82E16822136279
    Finding exact specs for the drive has been tricky, or maybe I just need to have the physical size verified.  What I know/have found is:
    5400rpm       (would a 7200rpm improve performance, or am I limited by hardware?)
    SATA II        (does this matter tese days?)
    2.5" drive   (needs verification)
    open drive?  (do I need this or not?)
    Any other options or advice?  I'd like to spend a small amount since this is an older computer and won't be around a whole lot longer anyway.  Thanks in advance!

    The link you posted above is for a WD drive,....dont get it.   WD drives (some) have SMS sensor coflicts with Mac, and the consumer grade western digital HD are the worst you can buy.
    Same as used by Apple below, best option, cheapest price.

    I will need to clone the current drive before it fails; is there an article in this forum on that?
    Easy, 3 clicks and sit back and let Superduper CLONE your HD.....about 40 mins average.
    Superduper is free and most of the pros use it (or carbon copy cloner)

  • How do I revert to Snow Leopard from Yosemite on late 2008 MacBook with no optical drive?

    Late 2008 MacBook. I don't need to back up, just to go back from Yosemite to Snow Leopard without a working optical drive.
    Thank you.

    If you have a Time Machine backup from Snow Leopard, then use it to restore from. Other than that, you will need to get an optical drive and run your install disks that came with your computer. Of course, you will need your Snow Leopard updater if you still have it since you can't get it from the App Store.
    I may be wrong about it not being available. I found a like from apple where you can still purchase it. It may still work.

  • Upgrading my Late 2008 MacBook Pro running 10.5.8 to Yosemite

    I just received a Late 2008 Macbook from a friend that he factory reset. I'm currently running 10.5.8 (very sluggishly) and would like to upgrade to Yosemite. I know I need to buy 10.6.8 before I can make the upgrade, but will my current hardware even be able to support the new software? I don't want to buy anything if I'm going to be running software too powerful for my mac.
    Product name: Late 2008 Macbook
    Processor Speed: 2 GHz Intel Core 2 Duo
    Memory: 2 GB 1067 MHz DDR3

    It should.
    Check that your computer is compatible with Mountain Lion/Mavericks/Yosemite.
    To check the model number hold down the option/alt key, go to the Apple menu and select System Information.
    iMac (Mid 2007 or newer) model number 7,1 or higher
    Your Mac needs:
    OS X v10.6.8 or OS X Lion already installed
    2 GB or more of memory (More is better - 4 GB minimum seems to be the consensus)
    8 GB or more of available space
    Check to make sure your applications are compatible. PowerPC applications are no longer supported after 10.6.

    Do a backup before installing.
    The 2 places I’ve seen recommended most to buy reliable RAM are below. I have purchased RAM several times from Other World Computing and have always been very satisfied with the product and service. They have on-line instructions on how to replace the RAM. OWC has also tested RAM above what Apple states is the maximum. I now have 6GB installed on a machine supposedly limited to 4 GB and noticed an improvement (2008 iMac).

    One option is to create a new partition (~30- 50 GB), install the new OS, and ‘test drive’ it. If you like/don’t like it it, you can then remove the partition. Do a backup before you do anything. By doing this, if you don’t like it you won’t have to go though the revert process.
