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.

Info:MacBookPro, Mac OS X (10.7.3)

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

May 3, 2010

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 :: 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 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.

MacBook Pro :: VLC Suddenly Stopped Playing MKV Files?

Oct 28, 2010

Out of the clear blue sky, VLC just stopped playing MKV files. I was watching a .MKV file just 15 minutes prior. I'll click on a MKV file and it'll just hang... or I'll open up VLC and open the .MKV file from there and it'll hang. Have the most recent version.

I went to preferences and changed the preload so it wouldn't load all the videos in the directory and it still doesn't work.

MacBook Pro :: Charger Suddenly Stopped Working?

Jun 9, 2012

Today when I tried to connect my charger, the charging light suddenly went out after a few seconds. It's never done this before, and now my computer isn't charging. I looked at several problems that were similar to this, and I've tried everything short of replacing the charger. I followed the link to the article that explains what to do in this situation; I checked absolutely everything on my charger that it told me to, and cleaned off the area around the magnetic pins. I tested the charger in several different outlets, with no results. 

I also followed the steps to reset the SMC. That didn't work either. Something else that's important to note is that there is an area on my computer between the MagSafe power port and the Gigabit Ethernet port that is damaged. The plastic covering between these two ports had broken off about a week ago, and there is a prominent gap between them. But, my charger was still working just fine before today. Could this damage still have something to do with why my charger stopped working?

OS X :: MacBook Trackpad And Keyboard Stopped Working Suddenly

Feb 10, 2009

It seems that during my afternoon class, I shut down my macbook and then when I went to use it about 10 minutes later the keyboard nor the trackpad works. Now the keyboard/trackpad is not defective as it works via the OSX install cd and it works in Windows Vista (dual booted) When ever I start up OSX it just comes up and the mouse is in the upper left hand corner, and the keyboard doesn't work at all. I have tried a pram reset by pressing command + option + p + r and that did nothing. When I am in OSX the only way to get out is to hold down the power button till the macbook turns off. What else could be wrong is there anything I can do, the nearest Apple store is about 80 miles away so I am trying to avoid that at this point as it seems like a software issue.

Two or three days ago, the topmost line of my keyboard (contains esc, brightness, expose, dashboard, play/pause, mute, eject, etc.) suddenly stopped working. Strangely, some of the keys have switched functions: expose opens a search bar, keyboard dimmer refreshes the webpage, keyboard brighter selects the web address, play/pause is now shows Spaces, skip forward is expose, and sound increase is dashboard. I reset my keyboard, but nothing changed.

MacBook Pro :: Internal Speakers Have Suddenly Stopped Working?

Feb 5, 2012

I had my computer plugged into some external computer speakers (nothing where I had to downlaod any software, I have used these speakers before), and when I removed them, all of a sudden the built in speakers weren't working.  I tried to adjust the vollume, but I get the volume image with a little "forbidden" circle and cross underneath.  I tried adjusting the settings in System Preferences, but when I got to the audio settings there was only the one "Optical digital-out port".  I then updated my computer, but still no luck.  Lastly I went to Utilities and to Audio Midi Setup to reset everything to the default settings, but I am unable to adjust everything. It's all that lighter shade of grey that tells me I can't select it.

MacBook :: Power Cord Suddenly Stopped Working

Mar 3, 2012

I was charging my macbook.It was charging when I left, upon my return, after about 30 minutes, I found that the light was no longer green. There was no light on at all. I tried restarting multiple times. There are no stuck prongs in my power cord. I tried different outlets. I tested the outlet to verify it worked. My computer will charge fine with other power cords, but just not the one I want it to use? Is there anything else I can try before purchasing a new cord?

MacBook Pro :: HDMI Output To TV Suddenly Stopped Working

May 28, 2012

I have a one month old "late 2011 model" unibody Macbook Pro where the HDMI output just suddenly stopped working with no changes in configuration.I've tried resetting the PRAM and SMC, switched HDMI cables, cold rebooting everything, tried different HDMI ports, different resolutions on the TV and switched audio output settings, nothing works. When I plug the cable in the Mac switches resolutions, recognizes the TV in the Displays preference panel and correctly identifies it as a Toshiba, but doesn't send any audio or video signals to the TV.

Desktops :: Mac Pro Suddenly Not Recognizing Discs / No Mountable Filesystems

Sep 28, 2010

Hopefully this is the correct place to post my question. Yesterday I inserted a movie DVD into the internal drive of my MacPro 3,1 and received the error message, "The disc you inserted is not readable by this computer". I tried several different movie discs, some old, some new releases I just purchased and I get the same message. Data discs work fine but not movie DVDs.

I also noticed that my Mac can no longer mount an ISO or DMG file. I get an error saying "No Mountable filesystems". I have repaired permissions, restarted, disconnected all external peripherals, etc. Pretty much all the basic stuff you try when your Mac isn't behaving as you'd expect. The odd thing is that it just started behaving this way within the last two days. DVDs played fine before and I could mount any ISO or DMG file. Only thing that is different is I ran the most recent security update from Apple when it popped up.

OS X :: Headphone Port On Macbook Pro Stopped Working

Aug 19, 2009

When I plug a set of headphones on my macbook pro, it no longer recognizes that headphones are plugged in. I have tried three different sets of headphones just to make sure that they are not the problem. In Sound/Output section of system preferences, it still says internal speakers even when the headphones are plugged in all the way.

Is there a fix for this I can do myself or do I need to take it in to an Apple Store?

MacBook Pro :: Display Port Stopped Working

I hooked my Macbook mini-display port up to my new Sony 32" TV and it worked fine for a month or so, but then it stopped working. Now when I plug it in the TV says there is "no signal" and the laptop doesn't detect the display. Nothing happens when I plug it in. I have tried two different HDMI chords, but only one mini display chord.

MacBook :: FireWire Port Stopped Working

Feb 27, 2010

The Firewire port on my MacBook has stopped working. Nothing responds and when you look in System Profiler with anything connected the Firewire section shows the spinning indicator for a few minutes before claiming it is unable to list devices. I have also tried all the usual troubleshooting steps including resetting the SMC. But, if I put my thumb under the connected Firewire plug and gently press upwards the port works. It shows in System Profiler and drives mount. I have, of course, tried with different cables to rule that out too.

It clearly seems to be a physical problem with the port somehow. Does anyone have any ideas of exactly what the problem might be, and how easy it is to fix? Maybe a pin just needs bending outwards, or the port loose and can a clip needs pushing back in. If it is likely to be something relatively simple I am comfortable with fixing it myself, but the laptop is a few years old and not covered by AppleCare so I am wearing of an expensive repair bill.
