Macbook Pro issues with WRT120 in 11n mode

WRT120 in N mode have the following problems
- When MBP wake from sleep, the wireless scan takes awhile (10s?) to find the router but doesn't connect. Forcing a connection to the router works.
- Occurs on 2 MBPs. A 2011 model and a 2008 model
- I can confirm the radio is in N mode by inspecting System Report->Wi-Fi->SSID->PHY Mode.
- Security is WPA2 Personal with TK2 or AES
Usability problem is bascially opening the MBP screen to wake up from sleep results in no network connection unless user force the connection.
WRT120 running the latest firmware (v1.0.07 build 2 released in 6/28/2012)
If I set to G mode (Mixed or B/G mode) with WEP. The wake from sleep scan finds SSID right away and connects perfectly quickly

I'm running latest OSX Lion on both MPBs and there are no additional driver updates.
The wireless chipsets are interesting.
- 2008 MBP has a Atheros WiFi chip
- 2011 MBP has a BroadCom WiFi chip
- WRT120N has a Atheres chip
There does seem to be quite a few problems with OSX Lion and WiFi connections. There are lots of online postings. This problem seems to be on Apple's end so I may have to wait for Mountain Lion to see if there is a fix.

Retina 13" macbook pro issue with defective USB ports?

I have a late 2013 13" macbook pro with retina display. I'm having persistent issues with both USB ports. Connected peripherals like keyboards or external USB drives either will not be recognized at all, or will take a very long time (minutes) to be recognized by the system.
I'm running the latest version of Mavericks OS X 10.9 (13A2093) at the moment, which includes the keyboard/trackpad firmware fix that addressed initial issues with this series of laptops.
I took it to the local Genius Bar a few days ago and the Apple Genius was able to get an external USB drive to mount (eventually) on each port, but now it seems that waiting several minutes for the external device/drive to be recognized does no good.
Is anyone else experiencing similar issues?

Here is an example of devices you should see in the Device Manager. Can you check what you have?

My macbook pros issue with battery.

I have a 13-inch macbook pro thats model was probably released around mid 2012. Last week I found my macbook to be completly off, I tried the power button, it didnt work, even though It was plugged in. But the charger was not even lit. I checked on another computer and it seemed to be working fine. I've learned that the battery was dead so I replaced it with another macbook pro I had that broke a while back. I replaced it and it worked, for a while. after an hour or so, It ended up not being recognized. I've tried using SMC and other methods which tell me to press the power button after, but every time i try to plug in the magsafe, it just turns it self on, and the battery is still not charging or being recognized in that matter. I'm all out of options. :I

I guess I'll have to get it checked then tommorrow, thanks anyway

Macbook Pro - issues with Display

I've been linking my Macbook Pro to my display but when I need to unplug my computer from the display, I put my computer to sleep first and then unplug all the cables. Then, when I try to turn my computer on from sleep mode (again, not connected to the display), it won't turn on and I have to restart my computer.
Also, is there a key where you can either use both displays (display and laptop display), vs just use the display itself (black screen on laptop display).

i have got the same **ing problem today,
as everyone here did, i heard the sound ,but the screen just stay black forever,
i try some methods, but they don't work.
I wonder if i need to send it to the apple store. I think apple should update some hardware for as during the repair.
My MBP was brought one year ago, and i love it very much.
Luckly, i have back up most of the important things.

HT4796 New MacBook Pro - issues with transferring info from old computer

transfer of data from a windows computer to a new MacBook Pro seemed to be proceeding smoothly with an original estimate of installation time of about 4 hours. Seems to have frozen up with 1 hour 22 minutes left - help!
Program has been running for 8 hours

Welcome to Apple Support Communities
If you are migrating using an Ethernet cable, unplug and plug it, so this transfer should continue. If this doesn't work, restart both and start the transfer again.
There are different ways to transfer files from another Mac or PC. The only way to transfer files from a PC is by using Wi-Fi or Ethernet, the worst for Migration Assistant because they fail and are the slowest ways

Macbook Pro 2009 has gray screen, safe mode won't work

I have a Macbook Pro 2009, with a new hard drive installed in August of 2013. I opened my computer a couple days ago to a gray screen with a prohibitory sign and a spinning gear that will not disappear. I have no backup and tried to backup my hard drive to an external drive in Recovery Mode, but I got an error message and the backup did not work: the image could not be created. So I decided to try Safe Mode, but the Macbook will not enter safe mode. Is there any way to get onto the computer just to backup a handful of files onto an external drive before I format my drive and start over? Am I doing something wrong by trying to enter safe mode? (I held down the Shift key after the chime and released it when the Apple logo and the gear appeared) Any help is appreciated. I've read all the topics in the forums I could find on this issue, but none of the directions seem to help. Thank you.

LisaLoParo,
no, you’re not doing anything wrong in trying to boot into Safe mode.
I can think of three possible alternatives to Safe mode to try:
If you have an external disk, you could boot from the grey Mac OS X Install DVD which came in the box with your MacBook Pro, and try copying files from your internal disk to the external disk;
If you have a bootable external disk, you could boot from it using Startup Manager, and try copying files from your internal disk to the external disk;
If you have access to a FireWire 800 cable and a second Mac with a FireWire 800 port, you could try booting your MacBook Pro into Target Disk mode so that it can be used as an external disk from the second Mac, and try copying files from your MacBook Pro to the second Mac.
You’d only need to try one of these three alternatives; if you try one of them and it doesn’t work, then you’d get the same result by trying either of the other two. Good luck.

Hi,
I just bought a new Macbook Pro 15" with SSD 256 Gb and its almost a brand-new (the 4th time to use the device) a while ago i was trying to connect to my home wireless network it said that the connection is timed out so i clicked the airport sign on the top it said that your airport is not configured then I restarted the system but it didn't restarted it showed the grey screen with the apple logo and the spinning wheel for more than 10min so I tried the force shutdown by pressing the power button till it switched off I waited for 5min then pressed the power button to start or boot the system and again the grey screen with the apple logo and the spinning wheel, I waited for more than 20min nothing changed, any solution please?
Your help is really appreciated"

Thanks a lot i followed the instructions for safe mode (i found out that i was pressing the C button after restarting) i did whats written there but the repair couldn't be performed so in addition i needed to re-formate the HD so i erased the volume and then repaired the disk--> quite disk utilities --> start the installation from the installation DVD.
Thanks really appreciating your help

Why does my macbook pro only start up in safe mode?

Last night i updated my macbook pro, and when it restarted it stopped at the logo with the spinning wheel, and it kept spinning for 20+ minutes. I shut it down by holding the button, and it will not start up again, every time the wheel just keeps spinning. I tried holding down shift, and starting it in safe mode, and that seemed to work. But that is the only way it will boot up, and I am limited to what I can do. How can I start my macbook pro up with out safe mode. I do not have my installation disk with me, and I do not have any of my stuff backed up, but I plan on purchasing a external hard drive within the next week to back up everything, incase I have to wipe my hard drive. But I will only do that at last resort...

MacBook Pro 3,1 15' 2,2 Core 2 Duo Late 2007.
I used the same buss speed (667 mhz) and the same type DDR2. Same number of pins.
I also checked what happened with 0 ram in slots, and then it started blinking constantly.
So it must see the RAM but the RAM seems useless for some reason...

MacBook Pro 17" with Intel Core 2 Duo startup freeze with 10.6.8?

With my MacBook Pro 17" with Intel Core 2 Duo, 2.33 GHz startup freeze with 10.6.8 - I had problems after several SW upgrades. Startup ends every time in a freeze or a crash, nothing is running, i am not able to type in the password. it starts in beginning with thin colored disrupting lines on the display and this get more and more and than freeze the system.
"Save Boot", startup with shift shows no problems, display is ok, no freeze. So something must new in the video-driver. Is there any driver what I can delete or any new software to help in this issue?

try to boot off the cd installazzione, when the screen appears to follow thePACKING screen viewing. If you've already looked in the manual are your problem?

New Macbook Pro 15' with Retina Display Keeps Freezing Completely

Last week I got a Late 2013 Macbook Pro 15' with Retina Display (currently running OS X Mavericks 10.9.1) . However since last Thursday it keeps freezing. It usually happens 2-4 times in a day. The entire computer will freeze completly, I'll be unable to move the cursor with the trackpad and the keyboard freezes up as well. The only way to ameliorate the problem is by shutting down the computer by pressing down on the power button and then turning it back on. When my Mac starts up again it works completely normally. Is anyone else experiencing this issue? I recently read that this was happening to some 13' Mac's (until Apple fixed it) however I haven't been able to find information regarding the same problem on a 15' Mac. Thanks in advance!

Mine isn't new model of retina mbp.
Now I'm re-installing 10.9 and I want to try it for some times.
However my mac is out of warranty and if it is a hardware problem there are no solutions for me (logic board change costs $1.000 or so).
After reinstalling 10.9, if I'll not resolve, I want to try to change thermal grease for GPU and CPU...

MacBook Pro i5 with retina will not recognize WD Passport even though I successfully used it to transfer programs and files from my older MacBook ten days ago. It receives power from the USB, but when using Time Machine I receive the message that there is not an external device connected.

If the modem is also a router, either use the modem in bridge and run pppoe client on the TC.. that is assuming ADSL or similar eg vdsl. If it is cable service.. and the modem is a router, then bridge the TC.. go to internet page and select connect by ethernet and below that set connection sharing to bridge.
Please tell us more about the modem if the above gives you issues.

Macbook Pro 13" with Retina Display for Photography work

Hi All,
I'm looking at buying a Macbook Pro 13" with Retina Display with the following specs.
2.6GHz dual-core Intel Core i5
Turbo Boost up to 3.1GHz
8GB 1600MHz memory
256GB PCIe-based flash storage
Intel Iris Graphics
Built-in battery (9 hours)
I need to use this mainly to edit RAW images as I'm a photographer and will be using this whilst onsite during a photoshoot. I have been advised that due to the graphics card, when using software like Photoshop, the laptop might slow down as it won't be able to handle the large files.
The only one that has a good graphics card is the MacBook Pro 15-inch: 2.5GHz with Retina display - with the following specs.
2.5GHz quad-core Intel Core i7
Turbo Boost up to 3.7GHz
16GB 1600MHz memory
512GB PCIe-based flash storage
Intel Iris Pro Graphics
NVIDIA GeForce GT 750M with 2GB
My issue with this model is the size and most of all the price. it costs 1000 more than the 13". Have any of you had the chance to use photoshop on the 13" version and how did you find it?
Thanks

Go step by step and test.
1. Reset SMC.     http://support.apple.com/kb/HT3964
    Choose the method for:
    "Resetting SMC on portables with a battery you should not remove on your own"

Pink color cast on macbook pro 15" with retina display

Hi,
I just got my very first apple computer a few weeks ago, but I had a annoying pink color cast of the display.
I changed my first deivce but even the 2nd had the same issue..
I noticed, that even the Apple logo shines in a pink cast, so it seems to be an issue of the display light itself.
Trying to calibrate the display with a spyder did not work, i got a very strange green color cast what seems to be clear, if the main problem is not the display itself,
but the display light.
I went to the Apple Sore in Hamburg and I found out, that all new macbook pros 15" with retina display had the same issue, but not older macbooks or some macbook pro 15" with retina display from clients.
As a photographer, I find this pink cast very annoying and I gave back my 2nd macbook pro 15" with retina display..
Is there a way, to get a macbook pro 15" with retina display without a pink cast, where the Apple logo shines in pure white instead of a pink color cast?
I don´t want a pink apple logo, nor a display with a pink cast..

WOW 0_o
Go back and get another one.. They will certainly try and make your day better by offering free items, try to get Apple Care free.
In all my time as being a technician I am going to have to put you on a list I have prestigiously placed for situations like these.
List of multiple repeat post-replaced failures.
Basically.. It's a list of all the people that have had to get a computer / part replaced and received the same issue again after the replacement.
HERE IT IS:
3x Logic board replacement (Warranty). I had to replace three logic boards for this one poor sod that had the same issue over and over again. In the end Apple gave him a whole new computer.
"" Same as above but happened to my friend the other day ""

FaceTime on macbook pro retina with Mavericks

I have just bought a 15" macbook pro retina with Mavericks and FaceTime has never worked. My account works fine on my iPad and iPhone but macbook version just won't connect and says 'FaceTime call failed. Can anyone help?

Hello there, alparkinsonpm.
The following Knowledge Base article offers up a few good steps for troubleshooting FaceTime on your Mac:
FaceTime for Mac: Troubleshooting FaceTime
http://support.apple.com/kb/ts4185
If you encounter issues making or receiving FaceTime calls, try the following:
Verify that FaceTime is enabled in FaceTime > Preferences.If the issue persists, or if you see the message "Waiting for Activation", try toggling FaceTime off and then on.
Verify that the Date, Time, and Time Zone are set correctly:
From the Apple () menu, choose System Preferences > Date & Time > Date & Time.
Enable "Set Automatically".
Click the Time Zone tab and confirm the closest city is correct.
Verify that both parties are connected to an active broadband Internet connection.
See Mac OS X: Troubleshooting a cable modem, DSL, or LAN Internet connection.
Consult Using FaceTime behind a firewall for necessary ports to open in firewalls, security software and routers.
If you encounter issues using a Wi-Fi network, use standard Wi-Fi network troubleshooting to resolve interference and other issues.
Verify the phone number or email address being used is the correct one activated for FaceTime.You can verify that you are using a valid Apple ID at appleid.apple.com. You can also create an Apple ID or reset your password from this website.
Verify that both parties have installed the latest software updates for their Mac and/or device. See:

Macbook pro runs really slow after sleep mode

My MBP ( MacBook Pro (13-inch, medio 2012), 2,5 GHz Intel Core i5, 8 GB 1600 MHz DDR3, Intel HD Graphics 4000 1024 MB), runs very slow after sleep mode. I notice that when I wake it up, my memory usage is nearly 8 GB. After a restart it is back no a normal level, between 2 and 5 GB depending on how many programs I am running. Any ideas what causes this? My IOS is Yosemite 10.10.2
Kind regards
