MacBook Pro 15 (2.4 GHz) Loosing AirPort Connectivity
I have a MacBook Pro 15 (2.4GHz) connecting via AirPort to an AirPort Extreme base station. At least once a day, randomly, my MacBook will drop the wireless connection, and then start prompting me for a password to reconnect. If I reboot the machine, it automatically reconnects to my saved wireless connection. I cannot seem to solve this problem - has anyone seen similar symptoms, or come up with a solution?
Suggest that you also cross-post over in one of the AirPort Forums.
The next time the MBP drops connection do the following:
System Preferences>Network
Click the Assist Me button.
In the next window that pops up, click the Diagnostic button & do the necessary.
Also, run the Airport Utility app which is located inside the Utilities folder.

Macbook Pro 10.10.2 keeps loosing wifi connection.
How do I fix my connection issues with my wifi. It disconnects numerous times daily. I turn off wifi and then back on to try to reconnect...it doesn't even find my network until I turn wifi off and on about 4 or 5 times and eventually my network will pop up and sometimes it doesn't so I am forced to reboot. I have 2 PCs, 3 ipads and 3 iphones on the network with no issues. I have also noticed the internet speeds on the mac are horribly slow. Any suggestions?
Please test after taking each of the following steps that you haven't already tried. Stop when the problem is resolved. Back up all data before making any changes.
Step 1
Take the applicable steps in this support article. The Wireless Diagnostics program generates a large file of information about your system, which would be used by Apple Engineering in case of a support incident. Don't post the contents here.
Be sure to test on more than one Wi-Fi network, if at all possible. A desktop computer can be tested with a mobile hotspot, such as the hotspot created by a cell phone. If the problem only exists on one network, then the access point of that network should be the focus of your attention, not the computer.
Step 2
Disconnect all USB 3 devices. If you don't know which are USB 3, disconnect all USB devices except keyboard and mouse.
Step 3
If you're not using a wireless keyboard or trackpad, disable Bluetooth by selecting Turn Bluetooth Off from the menu with the Bluetooth icon. If you don't have that menu, open the Bluetooth preference pane in System Preferences and check the box marked Show Bluetooth in menu bar. Test. If you find that Wi-Fi works better with Bluetooth disabled, you should use the 5 GHz Wi-Fi band. Your router may not support it; in that case, you need a new router.
Step 4
Open the Energy Saver pane in System Preferences and unlock the settings, if necessary. Select the Power Adapter tab, if there is one. Uncheck the box marked
Wake for Wi-Fi network access
if it's checked.
Step 5
Open the Network pane in System Preferences and make a note of your settings in the Wi-Fi service. It may be helpful to take screenshots of the various tabs in the preference pane. If the preference pane is locked, unlock it by clicking the padlock icon and entering your administrator password. Delete Wi-Fi from the service list on the left by selecting it and clicking the minus-sign button at the bottom. Then recreate the service by clicking the plus-sign button and following the prompts.
Step 6
In the Wi-Fi settings, select
Advanced... ▹ TCP/IP ▹ Configure IPv6: Link-local only
Click OK and then Apply.
Step 7
Reset the System Management Controller.
Step 8
Reset the PRAM.
Step 9
Launch the Keychain Access application. Search for and delete all AirPort network password items that refer to the network. Make a note of the password first. Turn Wi-Fi off and then back on. You'll be prompted for the password when you reconnect. Save it in the keychain.
Step 10
Make a "Genius" appointment at an Apple Store, or go to another authorized service center. -
Macbook Pro Core Duo 2 with latest Airport Extreme?
Since I'm having disconnection issues with my older Airport Extreme G router, I am considering getting the N version. Will it solve the issues I'm currently having with the Macbook Pro? Will I be able to connect to the 5 GHz band?
The answer is that the connection of my Macbook Pro, although not perfect, is more stable with the newest Airport Extreme N Router than with my old Airport Extreme G router. In the 5 GHz band anyway, which is the one I've been using for about a week now.

I have been able to get my MacBook Pro to print wirelessly through my Airport device. How do I make it so other computers (non-Mac) can also print wirelessly as well? They are able to connect through my wireless network but can't print.
Well, you could install the drivers to the wireless printer in you other computers.

How do I use AirPort Extreme to be able print from my MacBook Pro AND a PC. If I connect printer into AirPort, I can only print on laptop. If printer is connected to PC hard drive, I can only print on desk top. How do I configure this to make both print?
If you have not already done so, your chances will really improve if you....
1) Connect the printer to the USB port on the AirPort Extreme
2) Download and install Bonjour Print Services for Windows on the PC -

Problem:
Over the last few months I've had constant problems with freezing, shut downs. This might be in the form of I'll be working in iMovie editing some video and then mouse down into the corner to switch Spaces, the screen will half zoom out then just hang. Mouse won't respond, everything just sits there. I usually have to fix this by holding down the power button until the MBP turns off, then just reboot.
Other times I'll leave the computer on at night, wake up in the morning and it will either be off and as such, I just have to press the power button and it boots up again. Or the screen will be off, metal above the Function keys will be cooking, but the computer isn't responding, just a blank screen. I hold down the power button until it turns off and then reboot again.
These problems were getting worse. It has gotten to the stage where it might freeze a couple of times a day.
Seems the problem only occurs when the MBP is working. I might leave it rendering at night and wake in the morning to find it off etc.
Will also sometimes get horizontial lines in apps. I shut them down and start them up again and it's fine. But it's like the graphics card is struggling big time.
Actions to Fix:
- Started with repairing the permissions, but I always found that it had lots of items to repair, would repair then, but then if I verified again, the same things would come up as needing to be repaired. I also tried booting from the OS X DVD and repairing from that version of Disk Utility, but same result.
- Created new admin user account, to see if problem was just limited to my account. Same problem.
- Ran AHT from the MBP DVD that came with the MBP and it passed the hardware test. Though I couldn't find anywhere to make it run an extended test. The test I could run would only take about 10 minutes I believe.
- Erased the HD and fresh install of 10.6.3 from DVD, then software updates to 10.6.7 (yesterday). Repaired permissions after each step. After the OS upgrade I got a decent list of items that needed to be repaired, and after repair, would still show as needing repair. I checked the KB and it listed a lot of files that might get this error, but that it was ok to ignore them.
- Was editing video this morning in iMovie again, running Disk Utility on an external drive and boom, the MBP locked up again
I've gone through the /logs/crashlog in both the root and home user folders. After nearly all crashes these are empty, so it's not even reporting it anywhere.
Can anyone shed any light on whhat might be causing the problem?
<Serial Number Edited by Host>Actually, when I was at the Apple Store I had both laptops flat, with the screens at 90 degrees. Pushing the screen forward and back with my fingers (via the top of the screen of course), the 15" easily has twice the hinge resistance. With that kind of test, weight isn't a significant factor -- that 17" hinge on a 15" laptop would probably cause the screen to come crashing down, too.
There were a few people in these forums who said their 17" was actually too tight (wish I had that problem!). It seems like a quality/consistency problem that could easily be fixed by A) measuring the force required to move the screen back and forth before screwing the case together, and B) making the hinge tension adjustable. -
Which Intel CPU is used for MacBook Pro 13" 2.26 GHz
Hello,
I want to buy the above-mentioned MacBook Pro, however, I don't know which CPU model is used (P7550 or P8400), since I need the CPU feature "IVT" (Intel® Virtualization Technology) which is only available in P8400.
In some German discussions I got the information that both CPU models have been sold in Germany (checked with the tool CPU-X)
The MacBook Pro with 2.53 GHz (P8700) has also the IVT feature.
Does anybody know which CPU model is currently used in the MacBook 13" (MMB990*/A)?
Thanks for your feedback.
MichaelHello Rod,
Today I was in the apple store in munich and checked some mbp 13" 2,26 GHz systems. All had the 8400 inside. I shortly spoke with a saleman, however, he didn't know about different models inside the systems and told me, that I can't test the system locally, but I can check it @home and if i'm not happy with the system I could bring it back within 14 days.
My result from the mbp:
machdep.cpu.brand_string: Intel(R) Core(TM)2 Duo CPU P8400 @ 2.26GHz
machdep.cpu.features: FPU VME DE PSE TSC MSR PAE MCE CX8 APIC SEP MTRR PGE MCA CMOV PAT PSE36 CLFSH DS ACPI MMX FXSR SSE SSE2 SS HTT TM SSE3 MON DSCPL VMX SMX EST TM2 SSSE3 CX16 TPR PDCM SSE4.1
I compared it with your results and the only difference I found was an additional feature "SMX" (Safer Mode Extensions). I couldn't find out for what exactly this is used, but I seems independ of the IVT.
I believe that you are right, and the VMX corresponds to the "IVT" feature. If this is true, I could take any MBP 13"
What do you mean?
Thx

I recently updated? to Lion from 10.6.8(snow leopard), and things seem to be running slower. Has anyone had similar problems? I have Feb 2011 Macbook pro 13" 2.3 Ghz.
As Shootist pointed out, the system uses more power.
However, initially it will reindex the hard drive for spotlight, which will slow things down temporarily.
It also must rebuild caches that eventually will speed things up.
If it has completed indexing the hard drive (no dot pulsing in the spyglass), then there might be something wrong.
Start by booting into the Recovery HD (a partition created with Lion that has Disk Utility and reinstallation options) by holding down cmd-r when you restart. You can let go when the gray screen appears.
When it boots, select Disk Utility and Repair the drive.
If that doesn't speed things up, try re-installing the OS from the same Recovery HD. It won't delete any of your files, but it has helped some people whose Macs ran slow after installing Lion.
Also, how much memory do you have? Lion needs RAM so maxing your Mac out might also help. -
Ist mein MacBook Pro, 15", 2,53 GHz, Mitte 2009, mit der CS6 kompatibel? Welche Probleme gibt es dabei?
Du bist wahrscheinlich mit dem Problem, dass so viele von uns mit 2011 Maschinen werden mit - ein Defekt im Löten von der GPU, die erste wird allgemeine Ursache Bildschirm Probleme und schließlich zu einer unbrauchbar Maschine führen. Leider ist Apple die Anerkennung des Mangels und die einzige Angebot, das sie liefern den Nutzern ist eine Hauptplatine ausgetauscht werden - die bis $ 700 + USD aufrufen können.
Einige Leute, die lange vorbei sind, werden mit Garantie neue GPU eingebaut. Dieser Prozess ist sehr viel billiger als eine neue Hauptplatine und scheint eine dauerhafte Lösung für den Mangel an.
Um dieses Problem stoßen mehr lesen, siehe -> https://discussions.apple.com/thread/4766577?tstart=0.
Viel Glück,

Does anyone know what the model # is of the current MacBook Pro 15in, 2.3 GHz , 4GB memory, 500 MG HD? Is it MD103LL/A? My MacBook Pro (3 yrs old) was stolen and my ins co found this model at Best Buy for $1799. Want to know if they're same, specs? Thank you!
Yes, it is in the United States and Canada. In other countries, the LL will be something else.

Hello,
I have a Macbook Pro 17'', 2.4 GHz Intel Core i7 (late 2011). I dont know what happened but the screen shows red flickering pixels everywhere where it should be black, and light blue pixels where it should be gray, I had this problem twice, the first time it just disappeared by itself. Now it's been like this for days, I have really no clue.
Anyone with the same problem or solution?
This is how it looks like:
ThanxIs that a camera picture or a screen-shot? Is there any difference? i.e., can you capture the problems in a screen shot, or not?

Should I upgrade to Snow Leopard/ Lion using a MacBook Pro with 2.26 GHz Inetl Core 2 Duo Processor and 2GB Memory? Can my old macbook take it?
thanksYes. You should be fine with Snow Leopard, but Lion requires a minimum of 2 GBs of RAM. If you upgrade to Lion I would first upgrade your RAM to at least 4 GBs if your model supports it. Also, see:
How to Install OS X Updates Successfully
A. Repair the Hard Drive and Permissions:
Boot from your current OS X Installer disc. After the installer loads select your language and click on the Continue button. Then select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer. Now restart normally.
If DU reports errors it cannot fix, then you will need Disk Warrior (4.0 for Tiger) and/or TechTool Pro (4.5.2 for Tiger) to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
B. Make a Bootable Backup Using Restore Option of Disk Utility:
Open Disk Utility from the Utilities folder.
Select the destination volume from the left side list.
Click on the Restore tab in the DU main window.
Check the box labeled Erase destination.
Select the destination volume from the left side list and drag it to the Destination entry field.
Select the source volume from the left side list and drag it to the Source entry field.
Double-check you got it right, then click on the Restore button.
Destination means the external backup drive. Source means the internal startup drive.
C. Important: Please read before installing:
If you have a FireWire hard drive connected, disconnect it before installing the update unless you will boot from this drive and install the update on it. Reconnect it and turn it back on after installation is complete and you've restarted.
You may experience unexpected results if you have installed third-party system software modifications, or if you have modified the operating system through other means. (This does not apply to normal application software installation.)
The installation process should not be interrupted. If a power outage or other interruption occurs during installation, use the standalone installer (see below) from Apple Downloads to update. While the installation is in progress do not use the computer.
D. To upgrade:
Purchase the Snow Leopard Retail DVD.
Boot From The OS X Installer Disc:
Insert OS X Installer Disc into the optical drive.
Restart the computer.
Immediately after the chime press and hold down the "C" key.
Release the key when the spinning gear below the dark gray Apple logo appears.
Wait for installer to finish loading.
E. If updating:
Download and install update(s)
Use Software Update, or
Download standalone updater(s). -
Change SSD on Macbook Pro 17" 2.5 GHz intel Core 2 Duo late 2008
Now I'm using Macbook Pro 17" 2.5 GHz intel Core 2 Duo late 2008. I would like to know if it is possible to change my 250Gb HDD to a SSD? What is the max of Gb?
Yes, it is possible. The capacity of the drive is limited by what the manufacturers of SSDs are producing and, of course, by the depth of your pockets. Expect to spend $600-900 USD for a 250GB or 256GB unit and $1000-$1600 for a 512GB SSD.
