MacBook :: Laptop Doesn't Recognize External Keyboard And Mouse
Mar 21, 2012
When my laptop stopped recognizing my external keyboard and mouse I searched the discussions and found an answer that has worked, but only temporarily. It was to do a PRAM reset 3 times and when I do this the keyboard and mouse work fine. But when I disconnect the mouse and keyboard and then later reconnect it will not recognize them. I have repeated the PRAM reset 3 times each time this has happened (4 times) and they work fine but then there is always a problem when I disconnect and reconnect.Â

I have an HP printer hardwired to my iMAC and have been sharing the printer, wirelessly through the home network, with an older Powerbook G4. I've added a third laptop (Mac Pro) which also shares the Wireless network, but can see the Printer online. I get a message that the Printer is not Online.
why the third laptop can't see the printer online?

my mac book pro is not recognizing my WD 500 GB external hardrive. I checked and double checked to make sure the external was mac compatible before I bought : and it was. It also is not recongizing an WD external hardrive I borrowed from a co-worker. Here is what I have done and checked so far.Â
- I checked to see if the externals worked on other Mac Pros( just to double check mac compatibility)-Â they showed up on on 4 different Mac books.
- I checked to see if there was something wrong my usb ports. So I incerted my 4 GB flash drive in the USB port, and then my co-workers 4GB Flashdrive- My computer recognized both the devices.
- My computer was very full ( that is why I bought a bigger hardrive to back up my files) so I thought maybe there just wasnted even enough free space for my computer to recongize the devices. So I freed up 70GB of hardrive space on my mac book. - still nothing.
- I also checked to make sure I had the suggested software updates to run the drive, before I bought it. Â

So my friend was using his MacBook and went to do something else. He came back and the screen was black, he hit space and nothing, tried the trackpad and nothing. He restarted by holding the Power button, and it go to the log-in screen, but he can't type anything, or use the trackpad. He has tired restarting several times and no luck. He also tried an external Keyboard/Mouse and that didn't work.
He did plug in a Flash drive and the light turned on, so the USB ports are at least getting power, but nothing is working.

I've started installing XP onto my iMac, and it's at the screen where it asks what partition it should be installed on. In order to select a partition, I'm supposed to use the arrow keys on my keyboard, but my keyboard doesn't seem to be recognized by the installer, as well as other keyboards I've tried. So now I can't install windows. How can I get it to work?

so just like the title says I'm having some trouble as I did a recent upgrade to snow leopard and I have been beach balling a lot. I read that I should do a fresh install and heres where I ran into problems. My external HD is not appearing in finder. It used to work just fine before and it works fine on all of my roommates macs. I tried rebooting to see if it would fix the problem and all that happened was it made my bluetooth module say it was unavailable. Anyone have any ideas on what to do?

Have a iMac G5 with built in BT. I used it downstairs yesterday and took it back to the spare room where it usually is used. Fired it up today and I find that the BT mouse is fine BUT it ignores the keyboard. I tried; Replacing batteries. Checked that the suspect keyboard worked on my mac mini (it did). Tried my other BT keyboard on the iMac same problem. So, why does it recognise the mouse but not the keyboard? I do not have a USB Keyboard, so now I cannot Log in to fix it! I am guessing that the pairing has gone BUT surely it would simply see the keyboard as a new one and start setting it up. Something is stopping keyboards working with BT, very strange - could a loose BT module cause this? Or will I have to buy a USB Keyboard now to use my iMac?

I am using Apple Remote Desktop to control a Mac OS X Snow Leopard system with a Mac OS X Snow Leopard system. On the computer being controlled, I launch Windows 7 through Parallels Desktop Mac version 6. Once the VM is launched, for some reason it doesn't seem to recognize the keyboard as it will not allow me to Ctrl-Alt-Delete. I can use Ctrl-Alt-Delete through the keyboard menu, but I cannot enter in my Windows password.

Using Migration Assistant, I'm trying to transfer back-up files (whole system) from my Western Digital, External HDD to a new-to-me iMac which I've just purchased used. The External HDD has all my files (hopefully!) from my recently stolen iMac. As you can imagine, the circumstances are a bit unexpected and unsettling.
I've followed Apple's instructions for using MA with an external drive, but get hung up like others before me when it comes time for my new (used) computer to locate the disc from which to transfer the files. I've read the replies to others who have posted with similar difficulties using Snow Leopard, but resolving the issue seems to be just out of reach. Â
Original computer is now unavailable (stolen); it last ran on Snow Leopard, 10.6.3 to 6.8.New computer is used, and also runs on 10.6.8.Both computers are iMac 2009, tho slightly different versions, if that has any bearing on things.I created a temporary account on my new-to-me computer to make the data transfer, so that there wouldn't be an accounts conflict, as others have suggested.Western Digital External HDD, "My Book, Studio Edition," 1TB. I'm using the FireWire 800 port on the iMac. If I need to erase the hard drive on my "new" computer, I'll need a little instruction and hand-holding on that one.Â

my laptop (macbook pro) doesn't turn on, because the battery doesn't work (may be because of moisture), and the 7 battery lights on the left side are off, and when I plug the charger in, the light on the magnetic socket turns on so dim ..

my GF and a glass of Wine. Cat hits wine and wine hits MBP. The Mac shut off instantly, we acted pretty quick and mopped up and turned upside down. I then took back off and over the course of the next 5 days I have stripped it down completely including the Key board and cleaned as best as I could. I've put it all back together and it starts up, a reassuring tone rings out, then apple sign appears with a loading bar beneath, this takes a while then it reaches the Lion log in page.It still recognizes me, or rather my name as the user but refuses my password which I know is correct.The keyboard isn't backlit but keys are typing something (can't see characters, just dots). Screen brightness works.No back light on keys although this may be normal at this point, not sure.Â

I just bought 2 - 4 gb memory to ugrade my 2 - 2 gb memory on my macbook pro 13" early 2011. Installed them and rebooted. The About Mac still shows 4 mb memory and looking farther it shows it has 2 - 2 mb memory. Also, now when I close the lid on the computer and it shuts down completely and not just go to sleep. i do not know if the two are related.

I started having problems with Yosemite and lion (installed in the same hard drive, different partitions) so i erase all and instal mavericks, the macbook is late 2009 stock but i don't have startup disk, when i install mavericks it tells me that wont boot and it went an error trying to install, so i am able to boot with the alt key but my mac doesn't recognize de boot disk, when i try to select the startup disk on preferences it tells me: "You can’t change the startup disk to the selected disk. The bless tool was unable to set the current boot disk.", what i can do, i can boot with the alt key but it doesn't boot automatically.
