MacBook Pro :: System Randomly Disconnects Usb Device / Port Fails To Recognize IPhone
Dec 15, 2010
I have had several issues with the USB on my brand-new Core i5 macbook pro. It randomly disconnects USB devices. I've had the issue with multiple USB devices - same story with each one. Further, iTunes will only recognize my iPhone if it is in the port nearest the magsafe connector. The other port fails to recognize my iPhone entirely. Anyone else having a USB issue on their base 15" that was released today?
Furthermore, any suggestions of what to do about it? I'm having a hell of a time restoring my iPhone with this issue... And the Apple Store is over an hour away-I planned a special trip to buy this laptop.
I just bought a MacBook. So far I am loving it. Unfortunately a very strange thing happens. Whenever I download something with the Macbook every other device at my house becomes unable to connect to the internet until the download is finished. It doesn't matter if it is a WiFi device or not. The connected devices are: a WinXP Netbook, an ubuntu9.10 desktop PC (please notice this is connected with an Ethernet cable, it's not wifi), a WiFi and a Samsung Bluray reader. To complicate things even further, I noticed that even the MacBook itself cannot do anything else (such as browsing the web w/ Safari and/or Firefox). I tried to download large files such as a movie from iTunes store and the iPhone SDK. The download rate is about 600Kb/sec.
I have a 6Mb/sec DSL w/ AT&T and the modem is a 2WIRE 1701HG. Granted, it's pretty cool to have a laptop that can hose wireless networks. These are some info from my network: 2WIRE 1701HG Gateway Channel: 10 (2.457 MHz) Authentication: WEP-Open Encryption: WEP (tried also with WPA) Channel: 10 (2.457 MHz) Wireless Mode: 802.11b/g Maximum Connection Rate: 54Mbit/sec Power Setting: 4 SSID Broadcast: Enabled

I have a external SATA drive that was used on my old Windows laptop. The interface for the drive is USB 3.0. Whenever i try to view my files on the drive, the drive randomly disconnects, and notifications pop up saying that the drive was not ejected properly.
Also the drive has been reformatted to a Mac format, but it still continues to do this.
Info: MacBook Pro with Retina display, OS X Mavericks (10.9.4)
I own a few external harddrives, however one in particular (western digital 2tb) will randomly disconnect and a window will show about "device removal with the red little stop sign shape" then it will randomly connect again (and sometimes i have to physically unplug it and plug it back in), does anyone know what is going on here? None of the cables are being touched, it's really strange, the only thing i can think of, is maybe i have a loose usb cable and need to replace it? or maybe a faulty usb port?
I recently purchased the $1699 Macbook Pro a couple of weeks back and now it seems that my airport randomly turns off. I can't even get it to turn back on; I have to restart my macbook to get it working again.
I have had my new iMac 21.5" for about 2 weeks now. Yesterday I picked up a 500 GB LaCie USB Drive to be used for my Time Machine drive. I have the drive connected directly to a usb port on the iMac. Sometimes when the iMac goes to sleep, when I wake up the iMac I get the dreaded "This Drive Has Not Been Disconnected Properly" warning.
I have made sure that the "Put Hard Disk(s) to Sleep Whenever Possible" option is not selected under the Energy Preferences. I have tried multiple usb ports, same issue. This isn't a constant issue, it just happens sometimes. Is there anyway to tell Time Machine to mount and unmount my drive when needed?
Randomly, my computer seems to be disconnected from my wi-fi network. It is not a routeur problem since every other devices still work when the computer doesn't.

My brand new imac randomly disconnects from the internet. We have a BT hub - wifi. I have googled this issue and see that it is relatively common and it is incredibly frustrating. It is fairly simple to reconnect each time but it is driving me mad having to. It generally happens when the computer is asleep but sometimes in the middle of doing something.
Tonight I've been transfering all my files over from my old MacBook and everytime I try to connect my IPhone 3GS by USB to my Mac a message comes up straight away saying "A device conected to your computer is drawing too much power, apple has disconected this device to prevent damage occuring to your computer"
I have tried to connect my phone numerous times while it has been conected to the power cord and also running on battery.
It also took my new Mac a good half an hour to recognise my external hard drive was connected and let me use it..
I have had this problem once or twice with the same IPhone and my old mac so im thinking it may be a problem with my phone considering it is 2 years old now?
But then again, my old mac that is nearly 4 can still connect to my phone when my new MBP can't.
So, after getting it hooked up and connected to my router, which is set to only allow only 4 devices to have access to it (my comp, iphone, wii, and gf's laptop), i find that my gf's laptop (which is the only device using a corded connection) is the only machine able to get online without problems now.
I can pick up my WiFi network occasionally after a restart, but then it usually goes out after a random amount of time... anywhere between 10 minutes to an hour or 2.
I've been having problems staying connected on my Powerbook G4. The wireless works perfectly but the ethernet does not. I've been using the dorm ethernet jack to connect. The problem is that my computer can't maintain a consistent connection through ethernet so it randomly connects and disconnects. I called my campus' IT department and they told me that it must be my computer because they're system said that it didn't detect my computers IP address. I called Applecare and the person told me that it must be something wrong with either the network card or the ethernet port. Anyway, he gives me a case number so I can go get a repair. Unfortunately an Apple Store is far away from where my school is so I went to my school's bookstore instead.
The bookstore is an authorized service place. I drop the computer off to them and they sent it to Apple. I got a call today from the bookstore guy saying that the Apple technicians discovered that "liquid" had gotten into the motherboard and refused to service my computer. I was really angry when I heard this because I keep absolute care of my laptop. I know for a fact that no water has ever been around my laptop. I'm guessing it must have been negligence on the bookstore's part. I declined the $1300+ repair estimate so now its on its way back to me. I have a brother that works at the Apple Store and he just suggested going directly to an Apple Store this time. Will they just refuse warranty repair again?
I have a problem with an external hard drive WD Elements, fails to recognize the password I entered. you have a tip on how to retrieve it? even if it leads to the formatting of HD ...
I have a preamp connected to the audio in/out jack on my macbook pro 13" 2012. when i plug the audio in from my preamp the sound only shows it as a headphone output and does not list it under input. i also have no button "use audio for:"

If someone has me in their address book as Doe John and sends an email to me at my email address (johndoe@mail.com), Mail.app does not recognize me and asks me if I want to 'Add to Address Book'. The same happens if a sender has a minor change in the Name (such as even a dot in the name) of any recipient, regardless of the fact that I have the correct name in the address book. Mail fails to recognize the recipient even though the email address is identical, and will ask me if I want to 'Add to Address Book'. One would expect Mail to use just the email address and recognize the contact as already being in the Address Book.
I have a mid-2010 iMac. Recently, it has failed to mount DVDs, either video or data, on a reliable basis. I have been able to work around it by restarting my iMac, but that doesn't always work.
Info: iMac, OS X Mavericks (10.9.4), mid-2010 model
Since doing a clean install of Mavericks (which solved a ReportCrash loop problem), everything has been fine except..for some reason the 3.5mm headphone port refuses to acknowledge the existence of headphones when plugged in. The internal speakers do not cut out. No sound comes through the headphones. If I go into Systems Preferences/Sound/Output there is no option for headphones sound, just internal speakers.
I have tried everything (deleting .plist files and rebooting, booting in safe mode, PRAM resets etc etc). I have also tried various sets of headphones (mono, stereo and three ring headphone plugs). They all don't work on my MacBook Pro, they all do work (and make the internal speakers cut out) on my MacBook Air. It's not the headphones.
The port will happily recognize, charge and download my iPod nano. I am convinced this is an OS problem, as the port has not suffered any shocks, and it happened directly after a clean Mavericks install. It was working fine on Mavericks before the clean install.
I just got an iMac that had iTunes on it. When I plugged my iphone in it would just ask if I trust this computer. I said yes and there was no icon that recognized the device. Now, I just have a iTunes icon in the dock that will just bounce once when it is clicked. I have a 10.8.6 version. Do I need to find a new iTunes donload? Do I send the iTunes to the trash? Also, this did not come with the disk.
Ever since receiving my iMac back from the genius bar my external hard used by time machine randomly ejects. Apple Care had no answers for me. They told me I would have to research it then I would be able to fix it?
When I plug my iphone into my Macbook pro I get the chirp so I know it is charging but I don't get any icons showing the phone is connected nor do I see it on Finder. I also have an Air and my iPhone works great for that. I can't seem to find the setting difference that allows my Air to see the iPhone but it doesn't allow my Macbook Pro to see the iPhone.
Info: MacBook Air, Mac OS X (10.6.8), missing icon
My Macbook Pro will not recognise my iphone 5s when I plug it in with a USB cable, yet using the same cable with my ipad it is fine. (Also iphoto will not recognise the phone)
i have an ipad, iphone, 13" macbook pro and mac mini all which run fine. i bought new family macbook pro today but cant get my phone 4s to sync its data ie pics, music, contacts etc?
I get this strange message every so often, sometimes more often than other times. It says:
USB port drawing too much power. The device that is plugged into it will be deactivated.
There are only two things plugged into the USB-The keyboard and mouse. When I get this message, the mouse freezes. If I jiggle the mouse cable where it is plugged into the USB, it comes back and everything is fine until this message comes up again.
I currently have an external hard drive that has 2 FW400 ports that I use for Time Machine. I want to get at least 2 more external hard drives; one for storage of photos/videos and the other for another backup drive that I can rotate offsite with my current one. My internal hard drive is full and all of my USB ports are in use (however I do have a USB hub). I also have a Mini-DV camcorder that requires a FW400 port.
So, I'm trying to figure out what type of external hard drives I want to build/buy. I'm a little confused about daisy chaining firewire devices and hope someone can offer some clarification.
1. Can you daisy chain with a device that has only 1 of each type of FW port; 1 FW400 and 1 FW800? Or, does the device need to have 2 of the same type of port; 2 FW400's or 2 FW800's?..............
Image Capture no longer shoes my iPhone 4S as a device when plugged in. I've used it successfully for over a year but now it is playing up. I've changed cables, restarted the machine, my hubby has done a disk check. IPhoto recognises it still and the phone charges when plugged in. Have tried both USBs.
My Macbook pro is not charging. If I move the cord (specially at the Macbook charging port) it charges. But again if the cord is slightly disturbed then it doesn't charge. The problem got worse as my Mac randomly shuts down (especially when I remove the mag at the Macbook charging port). I dono what to do. Apple care (Genius) is far from my place.There is no visible physical damage on my mag charger. Could anyone suggest what I should do? I checked the battery status in system profiler and it says NORMAL. The details are as follows:
