Macbook no longer recognizes my midi keyboard

Hello folks. I'm having this problem where my macbook no longer recognizes my midi keyboard (M-Audio Radium 61.) I've had it working fine in the past through this midi to usb converter, and now the usb converter still lights up and shows data flowing when I have it plugged in, but for some reason the computer just doesn't seem to see it. The macbook also doesn't see this aggregate device I had working the other day too. But it sees other aggregate devices that are made up of the same outboard audio interfaces I have. Sunday was the first time I had my whole setup working with the keyboard running into Reason, out to Ardour via Jackpilot and out through my audio interface via the aggregate device (which is actually just made up of the inputs and outputs of my M-Audio FastTrack Pro because for some reason the computer sees them as separate devices... different point of contention...) Anyway, so now today was the first time I tried to set it all up the same way again since Sunday and I can't get them working. Any thoughts?

Since I upgraded to 10.9.5, my macbook no longer recognizes my external hard drive. How do I fix this? External hard drive is a 1TB Toshiba formatted for mac. Worked fine until latest upgrade.

Solved the problem by dumping my external HD onto another computer. Re-formatting and re-installing the data. Not what I wanted to do but it solved the problem.

MacBook no longer recognizes any devices that require the USB port (mouse, iPod, etc.)

After doing my latest software update, my MacBook no longer recognizes any devices that require the USB port (mouse, iPod, etc.). I've restarted the computer and that didn't help. Any thoughts on what to try? (I've already restarted the computer.)

Try using the procedures in this article to eject the disk.
Best of luck.

My iPad no longer recognizes my Zagg keyboard. Turned it off and on several times. One suggestion in manual is a dead battery. Where is a battery on a Zagg case? The iPad battery is fully charged.

My iPad 4 no longer recognizes my Zagg keyboard. Turned it off and on several times. One suggestion in manual is a dead battery. Where is a battery on a Zagg case? The iPad battery is fully charged and Bluetooth is on and the Zaggkeys PROfolio is listed but says NOT CONNECTED. What else should I try?

Well, you shoud tap the line where it says not connected, and it should prompt you to enter something. Regarding Zagg products, http://www.zagg.com/keyboard-cases/index.php?gclid=CIPgv7O_oL0CFQ8OOgodvnoA1w&ef _id=Uo5AsQAABFW6AX3n:20140320063435:s

Can GB08 recognize Specific Midi keyboard voices (Roland XP-10)

Hello all,
After searching the posts, I think I know the answer, but would just like to verify (set-up listed below):
Can GB08 recognize my specific keyboard (Roland XP-10) and its unique voices? I can play and recieve midi properly, but am limited to GB's voices. I specifically miss my fiddle...I guess I could simply play into a real instrument track through the line-in, but that kind of defeats the whole midi idea.
Christoph wrote in another post:
"No, GB doesn't know these synths, would be asking a bit too much. So you'll have to find the sounds using GB's internal synths or any external instruments (AUs or soundfonts) that you can find."
I have tried manipulating the instrument generator, but to no avail. I am still perusing the manual and discussions in hopes of finding a "duh" revelation, but any light you folks could share would be greatly appreciated. I am still trying to learn about AUs and soundfonts. I'm an old musician, but a GB newbie (was using cakewalk before).
Thanks in advance,
D
Roland XP-10 connected to MacBook pro via M-audio midisport 2x2 USB. MBpro recognizes the midisport 2x2 for what it is, but can it see the Roland out there on the other end....

I'd love some help trying to figure out why my 2008 MacBook no longer recognizes my external drive and now is not downloading photos from my iphone....?

After many years of having no problems at all on my Macbook, I recently figured I should finally upgrade my OS. I did that about three weeks ago, updating to Snow Leopard (10.6.8). I used Time Machine at least once after the OS upgrade but now Time Machine no longer recognizes the external drive I have used for all these years to back up. The MacBook does not "see" it. (Disk Utility does however.) The computer then also stopped recognizing another La Cie back-up that I have and now... my iPhone cannot download photos? Yikes.
I have, of course, shut down numerous times, used different cables (that worked for some) and the two USB drives. I even used a firewire. Nothing worked. I also tried to "Repair disk" on Disk Utility. It didn't work either, giving me an error (that I didn't save, sorry).
I read many other discussions on the file format of the external drive and of course I'd be happy to reformat the external drives--however, it is obviously a tad nerve-wracking to reformat drives before having an accessible back-up. Suggestions? I do not remember what file format they have but am pretty sure it's not the Mac file system someone mentioned. The drives are a 2009 WD "My Passport Elite" and La Cie 2007 d2 Quadra,
In terms of other hardware available, we do have another MacBook Air but it has started rejecting both drives as well (without the Snow Leopard upgrade). We have an old Dell but it wouldn't have the disk space to help out much.
Any thoughts on the process involved would be welcome. Any ideas on the iPhone rejection would be helpful as well! It is a 30gig iPhone 4 that has 20 or so gigs free (not clear as iTunes says that there are abour 18 Gigs on the phone but 24 free gigs? I may be bad at math but that's 40 gigs...).
I am checking out iCloud but apparently there are only 55 gigs available?
Will be glad to hear any thoughts. Thanks!

Good afternoon Lyssa,
Phew. First of all, thanks in advance...these blogs are always comforting help!
So, to answer your questions: For the age of the hard drive.Well, I added memory a couple of years ago (RAM and hard drive). Being a mom leads me to eat up a fair amount of gigs with photos of my kids and, in fact, I think I entirely replaced the original drive, so it is a couple years younger than 2008 since I did that in March 2010. If there is some way to verify that (whether or not I replaced the entire drive), I'm all ears. I have 311 Gigs free, so it is not a space issue. I verified the startup disk on Disk Utilityand nothing showed up.
Question 1- What formats...
The La Cie is format Windows NT Filesystem 3G ....At the time that I bought it I was still using a PC as well as a Mac and was told by afriend to use this format...
The WD is Mac OS Extended (Journaled). I again tried to repair the WD last night and this is the error message: "Error: DiskUtility can’t repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files."
Also, Time Machine tried again to back-up and gave me this error: "Files can't becopied onto the backup disk because it appears to be 'read only'. You may needto repair or reformat the disk using Disk Utility. If the disk can't berepaired, you must use a different disk for backups. Open Time Machinepreferences to select a different backup disk."
Question 2. Other cables...
I used two other cables with the WD and that didn't change anything.
Question 3... Fire Wire from the La Cie
Yes, I used the Firewire cable from the La Cie and it is indeed present, though still not visible in Finder. Since it is not Mac OSExtended I know that I can't use Time Machine with it.
So, in summary...
I can plug in the La Cie and it is functional on the MacBook, visible on Disk Utility but not visible in Finder. The WD drive is not visible and not functional. So we can think it is indeed the WD that is not working.... Also, the iphone photos did, in the end, get downloaded, so it is not something more general.
Causes...
I forgot to mention that there is a "lost+found" file on the WD which apparently points to a UNIX /OS issue?
Some kind of "insurance"?....
I'm curious about how people avoid this kind of issue. You just regularly replace back-up drives and hard drives before problems come up? Time Machine is great and saves many of us from disasters, however, knowing that your Time Machine back-ups are vulnerable makes the whole system insecure. No way to have alarms ring before the drive goes out?
As for ways ahead...
It seems that I ought to be able to copy off of the WD to the MacBook then erase it and reformat it and start over again. However, I haven’t been able to see its contents except on random occasions. If you have any ideas on how to copy the Time Machineback-ups from the WD, again, I'm all ears!

Macbook no longer recognizes Spdif cable

All of a sudden my macbook no longer sends anything through the built in optical output. Analog audio works just fine but it doesn't seem to recognize the optical cable anymore. It worked fine earlier this week, but now somehow it's dead. Theres no light from the cable and in the audio pref pane it says it's outputting through headphones and there obviously is no sound.
Does anybody know anything about this problem? I have never had problems with optical output before so I'm clueless.

My comuter does not recognize my midi keyboard

how do i make it recognize my midi keyboard

How are you connecting the midi keyboard to the computer? USB? Firewire?
What type of midi keyboard are you using? I use a Yamaha MOTIF ES 8. On my keyboard, there is a setting for my midi out port. For instance, I am connecting to my computer via a USB port. I have to set my keyboard midi out to "USB". Additionally, have you installed the midi driver for your keyboard in your system preferences? You need to let the computer know what midi channels you are transmitting and recieving on.
You might try setting your global midi I/O to "omni". That will transmit data on all 16 midi channels. OR...
Many people default the I/O to channel 1.
These are just some thoughts. I don't know if they are helpful. Good luck.

Macbook No Longer Recognizes External Hard Drive

Recently I bought an external hard drive (Toshiba Automatic Backup Portable Hard Drive) to backup my Macbook (Mac OS X 10.6.8). I found that in order to have my Mac recognize the hard drive, I needed to partition it by formating it to MS-DOS (FAT). I had no problems after that and began to back up my computer. However, the next day, I plugged my external hard drive back in and the icon no longer shows up. I went to Disk Utilities and found it there, but it said that it was not mounted. Then I went to System Profiler to see if it was under "USB" but it did not show up. I have tried shutting down and restarting my computer a few times but each time is no different. I even added a USB 2.0 Hub but even that didn't work. Is there anything else that I could do? I have files already on there and some I do not really want to lose. Is there any uncomplicated way that I could be able to make my mac recognize my hard drive again?

ellybook7,
In OS X you can read from an NTFS disk but not write to it - at least not without thrid-party software such as Paragon's NTFS for Mac.
I'm not sure what was working FINE in Mountain Lion that wouldn't work in Mavericks.

MacBook No Longer Recognizes WD External Hard Drive

I've trying to back up to my WD 1tb external hard drive, but my MacBook (2009) doesn't recognize it, which is strange because I've never had this problem before. I tried opening Disk Utilities but it doesn't show up there, either. I guess it's possible this is an issue with the drive, but like I said, I've never had a problem with it before and it seems to turn on fine when I plug it in. Currently running OS X 10.9.5. Really sorry if this is vague, I'm pretty lost and really desperate because I had a lot of important files saved on that backup disc. Any thoughts or advice would be really appreciated!

The WD hard drive itself is probably fine, the enclosure has likely failed. WD externals are notorius for cheap enclosures failing. Try a different cable first. You can take the drive out and install it in a better enclosure, like one from OWC.

My MacBook no longer recognizes any devices

Hello! I need help
I was using my laptop like normal. I was actually downloading pictures from some old discs i had (CDs) and I put one in and my mac didnt read it. Now I have a CD stuck in my mac and I can't eject it. I push eject button and nothing. After about ten minutes, the mac finally reads the CD and it pops up in the finder under devices but it is grey and I cant click on it. Then after another ten minutes the eject button shows up next to it, and I click in and nothing happens ):
My mac just freezes up. I also plugged in my Android and it did not read it either.
I think that its no longer recognizing any devices..what do i do?!
HELP ME PLEASE!
thanks!

My MacBook no longer recognizes its own screen!

Recently I started using an external monitor along with my MacBook's screen in order to have a larger canvas to work with. Recently the internal monitor on the macbook stopped working, even when I unplug the external monitor and reset it. Occasionally it will display a white light for a few seconds before going black and displaying nothing. Is this a common problem that can be fixed within the computer? Or should I look into getting a new screen?
