MBP 2011 usb problems

Hello guys!
Not long ago I purchased MBP 15" i7 2.0Ghz model and I got problems with usb ports on that machine.
Every USB device that is connected to machine keeps disconnecting.I cant transfer any large file from external devices.
Patriot supersonic flash device is broken due disconnects.I think its burned cos of that constant disconnects.
I have checked ports with many other USB devices and problem persists on all other ones.
So I made conclusion that USB ports are broken.

Macbook Air 2011 USB Problem

Hi, I recently bought a Toshiba portable hard drive that uses usb 3.0. For some reason, my mid-2011 macbook air 13" is unable to connect to the drive with the USB3 to microUSB3 cable. However, the hard drive worked on a late 2010 macbook air 11", other macbooks and pcs using the usb3 cable. The Toshiba portable hard drive did work with my 2011 air with my friend's USB2 to microUSB2 cable so I decided to buy one on Amazon. Unfortunately, the cable that I bought from amazon did not work with my macbook air but it did work with my other pc.
My question is: Does my macbook air have a usb problem and should I go to apple store to get it fixed?
Thanks!

There have been more than a few threads on this subject of the USB 3.0 Toshiba Canvio problems. Here is an ongoing rather current discussion of the issue.

[HELP] Installing Windows 7 on MBP by USB using Boot Camp

Hello!
Im using boot camp to try to Install windows 7 on my MBP. The problem is my cd/dvd driver is broken and I cant use DVD to boot from. I tryed to install by USB but when Im about to restart and boot try to boot the windows that I installed on the USB it says: 'No bootable device -- insert boot disk and press any key'
I have read that Apple changed in boot camp that if you have a DVD you cant use USB function to boot from in USB. I have fixed this problem by using this method from a video in youtube: http://www.youtube.com/watch?annotation_id=annotation_587318&feature=iv&src_vid= I3MNnbtfyzs&v=KmHxkahbK-g
But after I changed this I stil get problem when I boot that my laptop dont recognize the USB.
I need a help to solve this problem. Im using a MacBook Pro 13 (late 2011) OS X 10.8.5

I dont have the opportunities to repair my internal optical drive. Im looking for other solutions for this problem, there I can install the windows without the optical drive.

Macbook pro late 2011 starting problem

I'm running OS Maverics 10.9.3 version on Macbook pro late 2011. Few days ago the OS got much slower than normal system. Then i installed the the new OS but it was good for few hours. Then after few hours it became slower again. Then I changed the HDD and installed the new OS. But I found the same problem again. Then I removed all backup files from the HDD. After removing all items it became to work normally. But after 15/17 days later when i'm trying to turn on the macbook a flashing folder icon appears then i pull down the display for a while. When the lights gone then i turn on again and it works normally. I tried the internet recovery option by pressing the (ctrl+R) button but it takes much time. But nothing happened. What is the problem?

Try this:
Boot into recovery (OPTION key down) and select the recovery partition.
From the 4 option menu select Disk Utility.
Run Disk Utility>First Aid, Verify and Repair.
If it says the disk cannot be repaired, replace it with a new HDD.
If it says it is good, take out the disk, place it in an enclosure and connect it to the MBP via USB.
If it boots the MBP, then the internal SATA cable is faulty and should be replaced.
Ciao.

My MBP 2011 can't detect microphone, why?

My internal microphone works perfectly fine but when I insert an external microphone, my MBP fails to detect it. When I go to System Preferences>Sound>Input, nothing changes in the "Line In" area when I plug in my microphone. When I try to speak into my microphone, it's not picking up any sound at all. My headphone port works fine.
NOTE: My MBP 2011 went in for a logic board replacement/repair 2 weeks ago at an Apple Store. Is it possible this microphone issue is caused by a logic board problem?

This because line level is not Mic level, line level requires about 60 dbv/dbu or more or less of electrical gain (depending on voltage in to load specifications, db short for decibel is not necessarily a measuremet of SPL, sound pressure level, it is a mathematical equation reducing complex equations to a unit of measurement to use in math expressions...very simply put) than a microphone can generate.
You would need a mic pre-amp/mixer to provide a line signal, a mic can not provide anywhere near this level.
This is a very simplified explanation of the electrical therory at work here, and I don't think you are probably interested reading quite complex math equations that "crunch these numbers.
If you do an online search you will find a plethora of pre-amps that will boost this level up to line level, or you can look in to something like the Griffin iMic USB interface which will allow you to use a mic level signal into your USB port easily and affordably.

Logic Pro 9 and Access Virus TI2 on a MBP 2011

Hi,
I am struggling for over a month now to make my Access Virus TI2 and MBP 2011 to work together
but I keep getting a communication error in Logic Pro 9.1.5:
A communication error has occurred. The Virus TI does not respond to request messages or the transmitted data is corrupt.
I am having my setup as simple as it could be. The Access Virus TI2 is connected to the MBP through USB.
I have contacted Access Music, they claimed the error to be result of the USB communication between the two machines. They suggested me I use a usb hub. I bought one and now I am using it but there is no change. The error persists.
I was wondering if someone else is having the same setup and if he faces the same problem. If yes, how did you resolve it?
Thank you

Mini DisplayPort - VGA and MBP 2011 not working

Hi,
I can't get my 13" mbp 2011 to connect to VGA screens. I've bought a mini DisplayPort to VGA converter (an Apple one, not a no name) and if I connect a display over VGA the screen stays black. My mbp recognizes the display, I can see the display's model, resolution etc but no signal. I've tried multiple screens, none work.
I don't have other converters so I can't test if HDMI screens for example do work.
Anyone else having this problem?

I have a 2011 13" i7 and am having the same issue when connecting it to my LG TV through the HDMI adapter. However when I connect it to my HP external monitor it works but it's VERY blurry... so blurry that it hurts the eyes to look at it for more than a few mins.
My previous MBP (2010 13") works fine however with both the TV and monitor. I even reconnected it just to make sure and they both work flawlessly.
I only have 14 days total to return this new MBP and 5 of those days are used up so if I can't get this fixed by then I have no choice but to return it and go back to my old MBP.

After SMC reset, MBP 2011 with Yosemite OS cannot restart

My MBP 2011 which I recently upgraded the OS to Yosemite has been giving me endless problems when it restarts or reboots. when the power button is turned on, it starts up with an apple icon with a loading bar below it. The bar progress rather slowly and somewhere before reaching the halfway mark, the whole computer shuts down and restarts by itself. This process can actually go on for like 24 hours without a single break and the last experience I had was thaynir has been restarting and shutting down for the past 72 hours!!! Finally, I did a SMC reset by removing the battery cable, pressing the power button without the battery (5secs) and got the unibody assembled, plugged in the MagSafe and tried turning it on.
to my utter shock, after the SMC reset the MBP now cannot be turned on, no lights indicated at the MagSafe and it is completely dead. What do I do??? Please help folk!

You need to take it to your local Apple Store and have it checked by a Genius. Thats the best and safest option available to you now.

Defect MacBook 2011. Problems with the video chip.

I was faced with the legendary defect MacBook 2011. Problems with the video chip. Heard about what Apple makes replacement chips for free. My friend a year ago made the change in the service center. Is this true now?

Since Apple says that some copy protected DVD's will not function with Disk Sharing, you may need to "clone" the DVD, using the MBP, to a flash drive, and use the flash drive to perform the installation of the software.
Another alternative is to download and install the Trial version from the Microsoft Office For Mac website, and then use the activation code provided with the DVD to activate the full version install of the trial.

MBP 2011 Screen brightness changing regardless of the ambient light

As stated in the subject my brand new MBP 2011 screen brightness changes on its own, yes i know about the ambient light sensor, but my screen is going from med brightness all the way to minimum brightness even though the ambient light is constant. yes I know i can turn it off, but why build in an ambient light feature that just makes the screen go to mimimum brightness when in a well lit room??
or do i have a faulty one??

I too have this problem on my spanking new MacBook Pro. Called AppleCare and they said they weren't aware of this issue.
Meanwhile, this is my 1st mac. Had it for a few weeks now. Decided to open iTunes for the 1st time. The whole MacBook Freezes, no mouse interactivity, reboot required. This happens EVERY time I start iTunes which I no longer do. Apparently it's a known issue which Apple has patched(unsuccessfully). But hey c'mon, I mean iTunes? This is one of the core apps which SHOULD be tested extensively against the hardware. When you consider Apple PROVIDES the hardware, this is simply unacceptable. Unbelievable even. I simply can't believe how poor this is from a major company. But hey my MacBook Pro LOOKS GOOD right, so who cares if it's a technically malfunctioning piece of junk.
Here's my theory. Is part of Apple's patch deliberately reducing screen brightness without user authorisation when the MacBook starts to overheat, all because they know they've been incompetent/negligent with their QA testing and the hardware can't handle the software? If so, why have users not been informed?
I'm from Australia and we have this so-so comedian called Chris Lily who fans have taken to calling a genius, the joke amongst non-fans being the word genius has been dumbed down over the years to be almost meaningless. Anyway, maybe a certified Apple 'genius' can explain the reasoning for the apparently deliberate brightness reductions?

MBP 2011 Discrete Video Card Freezes iTunes

I just got an MBP 2011 17" 2.2Ghz i7. I have not run into any overheating issues (as addressed in other topics). However, I have isolated a very odd conflict with iTunes and the discrete video card. I can play games such as Starcraft 2 using the discrete graphics card without incident, so the card itself seems to be working fine. Somehow iTunes brings it to it's knees, though.
If I am using dynamic video card switching or have the discrete card selected and open iTunes, the entire OS locks up for about 10 seconds at a time, with about 1 second in between each lockup where things process. My mouse is free, but other applications are also locked up. If I quit iTunes, the problem goes away within 10 seconds or so. If I switch to using the integrated graphics, I can open iTunes and use it without a problem, no lockups at all.
I have tried completely removing iTunes (including all applicable plists, etc), then re-installing. No change. I have also tried re-installing Snow Leopard entirely and opening iTunes immediately after install. No change, still locks up. The Console app does not report anything relating to the issue that I can see.
I have the problem isolated and repeatable. There is some conflict between iTunes and the AMD Radeon HD 6750 discrete video card. Is this happening to anyone else? Does anyone have any ideas to try? Or is this just something that will be fixed by a new video card driver released by Apple in the near term?

Hi,
I do have the problems to, didn't know it was a problem of iTunes. I thought it might be my ram(changed it myself to 8GB ram to save 160$!), or my harddrive(changed it to 7200rpm that i already had).
Greetings,
TNAJanssen

MBP 2011/MC724 performance decreasing after firmware updating

On the third day after buying a suddenly degraded performance. No additional software installed (except for the adobe flash player).
Perhaps the problem is caused by a firmware update. I've Installed it from the standard upgrades. System Restore from DVD (with full HD cleaning), not solve problem.
Current performance can not even watch videos on youtube.
Who else is having the same problem with apple mbp 2011?
What do I do with it? How to fix the problem?
thank you in advance for your help.
Sasha.

youtube, safari, showing spaces and so on. Heavy freezes. Even during the first boot (after recovery from the DVD) when the music plays, there are freezes and crackling sound.

i am really tensed what do i do pls help me

If AHT doesn't show any issues, your best bet would probably be to take it to the Apple Store. The AirPort (Wi-Fi) card may have been unseated from its original position. If there is a problem with the card Apple should be able to replace it for free.

MBP 2011 15 late edition: missing HD space - hd shows usage to be 237 gb, but if adding up amount used by adding up apps, library, systems and users only 65 gb of use shows up?

"Hacked" is not my terminology, and I don't believe it's intended to be derogatory. What you describe is a perfectly legitimate reason to alter Hosts.
If your Mac still isn't working as expected after uninstalling Intego and Trend Micro, read on. The necessity to have a reliable backup cannot be overstated, since what you describe may be an indication of impending disk failure.
Back up your Mac if you have not already done so. To learn how to to that read Mac Basics: Time Machine backs up your Mac - Apple Support
If your Mac is momentarily unresponsive, consider the following.
Launch the Console app - it is in your Utilities folder. You can find it by selecting Utilities from the Finder's Go menu.
If the log list column on the left is not already displayed, show the log list by selecting Show Log List from Console's View menu. Select Show Toolbar if it is not already shown.
Locate system.log in the list and select it. Many date and time-stamped entries will appear, hundreds of them, and you must find the entries relevant to your Mac's problem.
To do that click the Clear Display button in the Toolbar. All previously displayed log entries will be disappear.
Next: Perform whatever actions cause the Mac to exhibit the slow behavior. If the problem is caused by errors logged by the system, the Console window will show them being recorded in system.log.
One or more of them, along with their time stamps, may reveal the reason for the problem you describe.
Copy and paste those log entries in a reply. If hundreds of the same repetitive messages appear, please edit them before posting. There should be no need for more than a few log entries.
Most of the entries will be cryptic but will contain information you might consider personal such as your Mac's name. If you do not want that information to appear, delete or obscure it when posting your reply. Leave enough information so that the entries can be deciphered.
