MacBook Air :: USB Port Suddenly Stopped Recognizing Devices?
Aug 4, 2010
I was playing Starcraft 2 on my MBA and the computer just shut down all of a sudden. Then when I booted back up the USB mouse I had plugged in doesnt work. I've since restarted and plugged in various things and it still doesn't work.
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.
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.
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]
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.

I am connecting a Canon 5D to my laptop trying to use it as a webcam trough camtwist.At the same time I need to output the streaming to a videoprojector.The cam is connected to the mini display port do there is no port available for the VGA cable anymore.†Do I need to use a different port for the projector? Should I buy a video card?Can't connect the camera via USB as that is too slow and it will freeze.
I have the need to connect an external monitor and a firewire cable to my Macbook Air, but with only one Thunderbolt port I am trying to determine if this is possible.¬† Is there such an adapter that would take my single Thunderbolt port and 'split' it into two?
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.
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?
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.
I have a network printer setup at my house, and it suddenly stopped working. Here's my setup.
Mac (printing computer): Macbook Pro, 10.6.3. Router: Generic router. "Server": Acer netbook running Windows 7 Ultimate Printer: Samsung CLX-3170 series color laserjet I use LPD and this is what I type in:
192.168.10.9 (This is the netbook's IP address.The printer's sharename in Windows 7 is CLX3175.This printer was working fine, but it just suddenly stopped working just now. Does anyone have ideas?
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.
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.¬†
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?
My Gmail worked fine for about a year now, then this week it just stopped being able to connect! It tells me that it cannot connect to googles imap servers or there there was an error connecting to port 993! I'm so frustrated, I've tried a restart, and deleting and readding the account but nothing. I even tried configuring it with POP setting over imap. Still nothing!
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.

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.
I am receiving my .me email on my ipad and iphone - both upgraded to ios 5.1, but suddenly stopped receiving .me email on my Macbook Pro (10.6.8). The processor on my laptop will not allow me to upgrade to Lion. I have been receiving .me email on my Macbook for the past month after moving to icloud.
I am trying to download a file from a cruzer micro 8gb thumb drive to the quickbooks program on my parallels VM. The VM is running XP. It keeps telling me to close the application that is using the cruzer. No apps are running except for the finder . This is on an '07 macbook with leopard.I also cannot find the cruzer on the mac os anywhere.
