Mac Pro :: Ejected External HD And All USB Devices Stopped Working

Mar 15, 2012

I've got a 2008 Mac Pro running Snow Leopard, and there seems to be some problems with my USB "system". When I eject an external hard drive, my usb mouse and keyboard will stop working for a short while, sometimes requiring that I unplug and plug them back in. Also, when I try to set my default audio input/output device to my USB interface, it resets every single time I turn the computer on and off. Not sure if these are related, but it seemed relevant.

MacBook Air :: Minidisplay Port To DVI, Not Recognizing DVI Monitor

Feb 25, 2012

I have the latest model of the MacBook Air 13" (mid-2011 model). As recommended by the Apple Store rep, I bought the minidisplay to DVI adpater to connect my 20" Viewsonic VG2030wm. Unfortunately, the MacBook Air 13" is not recognising the monitor. It doesn't detect it at all.

I know the monitor and the DVI cable work because it works with my original MacBook Air (2008 model) that uses a micro-DVI to DVI adapter. My last resort is to take the new MacBook Air, the Viewsonic monitor, cables and adpaters to my local Apple Store to see if they can figure out it out. However, I won't be able to go until two days later when I have access to a car.

OS X :: Air Port In Mac Suddenly Very Slow - How To Fix It

Nov 2, 2010

so for about 6 months I've been using my iMac's ethernet connection as an Air Port for both my iphone and roommates pc around the house. recently I was using my phone and the wifi all of a sudden was horrible, playing a quicktime video that took 2 seconds to begin before was literally impossible to play, and when switched to edge it was much faster.

I thought that something was acting up with my iphone and shrugged it off but my roommate soon complained the internet was being really slow on her pc. So I checked my Mac and it's internet connection was fine. The Air Port was on, I reset it, switched channels but same performance.

MacBook Air :: USB Port - Is It Multi Usable

Apr 28, 2008

I have a brand new MacBook Air which currently has a Superdrive attached to the USB port. I'd like to get a mac compatible digi camera and my wife wants an ipod. Can I simply disconnect the drive and connect the camera/ipod at will or do I have to buy a hub? On my old XP machine it seemed to me the ports were dedicated to their peripherals.

MacBook Air :: Trackpad, Keyboard USB Port Not Working?

Dec 21, 2008

I have a 2 Gen MBA and today suddenly the keyboard, trackpad and even the USB port stopped working, I tried connect an external mouse but it didn't work, even other USB devices are not working !! I tried the display port it is fine, but I am not sure about the audio port. I tried the SMC reset but it did me no good.

I had bought the MBA from Apple UK but currently I am in INDIA for my winter break from UNI. I don't have my OSX discs at the moment they are back in UK, I tried calling the Applecare but they are closed being a Sunday, and I don't want the local Apple Authorised Service center to touch my air as I don't trust them (The appointment of these repair centers in INDIA is not upto the highest standards !)

The keyboard and the trackpad are working in the Apple hardware test, I was able to move around the cursor and even use the keyboard to select the various options, so I believe the hardware is fine.

So any suggestions what can I do in the meantime, I will call Apple Care in UK tomorrow. I am not back in the UK till the 26th January.

MacBook Air :: ITunes Said IPod Should Connected To A USB 1.1 Port For Better Performance?

Dec 10, 2010

I was finally converted and have been using my new macbook air for a few days. (13.3" baseline w/ 4GB RAM)Everything is fine (I even installed Windows 7 via bootcamp and no slow down on starts up on both OS) until I connect my 80GB iPod.iTunes said "The iPod is connected to a low-speed USB 1.1 port. For better performace, you should connect it to a high-speed USB 2.0 port, if one is available on your computer."Not only it said it is slow, I have tried copying stuff from my iPod onto the MBA HD and it REALLY is slow. (47 mins estimated time for a 2.6GB file) All softwares are up-to-date coming out of the box.

MacBook Air :: Strategies For Dealing With MBA Single USB Port

Dec 14, 2008

I wanted to know how some of the rest of you who also have MacBook Air computers have been dealing with the fact that these machines only have one available USB Port. The single most inconvenient aspect of this is that, due to the mere 80GB hard drive I have installed in my MacBook Air, I use an external USB hard drive to store my iPhoto Library on and then when the time comes that I want to copy photos to my iPhoto Library, there's no way to do so because the SD card in my camera has to be plugged into my MacBook Air via USB.

I've found three solutions for dealing with this problem.
1) Copy the photos from the SD card to my MacBook Air's internal drive first, the disconnect the SD card and connect the external hard drive that has the iPhoto library on it, then copy the photos to the iPhoto library from the MacBook Air's internal drive.

2) Use a USB Hub to provide a means of connecting both the external USB Hard Drive as well as the SD card via a USB card reader. The one major problem with this approach is, to the best of my knowledge is, that it would have to be a powered USB Hub (in order to provide the power required to run two external hard drives - SD card & USB HD). This means that my ultra thin, uber-portable MacBook Air is now tethered to a power outlet.

3) The third and final method I've come across that I've most recently been playing with is through using the Eye-Fi Wi-Fi SD Card. This awesome little device, which Time Magazine has just listed as one of it's top 10 gadgets of the year, is truly incredible, you can read more about it here. This device would totally and completely solve my problem if it were not for one major detail, it's not compatible with RAW images (which for obvious reasons, I would much rather be using than JPEG). This one simple fact is most likely going to wind up being the deal breaker.

MacBook Pro :: It Suddenly Not Recognizing WD Passport

Jun 10, 2012

I have a MacBook Pro- purchased in September of 2011- that has now stopped recognizing my WD Passport. The Passport works fine with my wife's PC laptop, but is not showing up on the MBP. The light on the Passport flashes, but that's all. It does not show up in the Finder and Time Machine is unable to perform backup.

I have first restarted the MBP and then shut down and then turned the MBP back on. Neither time did anything. I have an older SimpleTech external that it now recognizes again- after appearing not to. After multiple attempts and using both USB ports, sadly have gotten nowhere.

MacBook Air :: FYI Failed Boot Of Knoppix DVD Required SMC Reset To Revive USB Port?

Feb 9, 2010

I had hooked up the MBA SuperDrive and wanted to see, just for fun, whether the machine could boot from a Knoppix DVD. (Knoppix is a Linux distribution that can run straight off the DVD without touching the harddisk.)

I tried and it seemed to work fine, until I got stuck on a blank screen. Oh well.

I switched off the MBA by holding the power button for >4 secs and it shut down. Rebooted, and noticed that the SuperDrive didn't make any noise. Once in OS X, I didn't get an icon for the DVD. Hmm. Hitting 'eject' didn't do anything.

MacBook Pro :: Mix USB 2.0 And 3.0 On Same Port Is Whole Port Slowed Down?

Jul 3, 2012

I have just ordered a new MacBook Pro and it does not have enough USB ports for my needs.If I have a USB 3.0 hub and I mix USB 2.0 and USB 3.0 peripherals on it, will the whole hub/computer USB 3.0 port be slowed down to USB 2.0 speeds?I am thinking back to Firewire, if you have Firewire 800 and 400 devices on the same chain, the whole chain slowed to Firewire 400 speeds.I don't think this is the same with USB but wanted some reassurance..

MacBook Pro :: FW400 Port Not Recognizing Any Peripherals

Aug 27, 2010

I recently bought a used (early 2008) MBPro 15" 2.5 SR to do some video editing. Unfortunately it will not recognize my Sony DV camera, or an external HD connected via FW400 or my 12" PB booted in target disk mode. The camera and the hard drive both mount instantly on my 12" PB and a friends 15" PB. Also, when I check the Firewire status under System Profiler all it says is: Warning: Unable to list FireWire devices (in red). This is regardless of what is connected to the port or if nothing is connected to the port. I have tried rebooting the PRAM and changing the Firewire port's network preference to OFF as recommended by this post: [URL]

MacBook Pro :: Stopped Recognizing All 4Gbs Of Ram - Down To 2Gb

It went from having 4Gb yesterday (or the last time I checked it anyway) down to 2Gb. I'm using a Macbook Pro Unibody bought in July 2009. System Profiler says that it only has RAM in one slot. What's going on and how can I sort it? After Effects is also saying that it can't multi-process - I was able to previously so I'm confused on that too.

MacBook Pro :: USB Port, Drawing Too Much Power - A USB Devise Is Currently Drawing Too Much Power And The Port Will Be Deactivated

This is my first post on the forums, although I'm planning on looking around in here once in a while, to see what people are posting.

For starters, I just wanted to tell you about this little problem I've been having with my MacBook 1,83GHz.

Sitting at my desk at work one morning, peacefully drinking my coffee, I suddenly received a rather discomforting error-message from my shiny new (about 1 month old) MacBook;

"A USB devise is currently drawing too much power and the port will be deactivated.".
