Software :: Unable To Use Keyboard To Boot
May 15, 2010
There is a strange thing happening with my iMac. I have a Core Duo 2.0 GHz with 2GB of RAM. I'm now using the most recent Apple USB keyboard with the chicklet keys.
I no longer can boot off a DVD or CD using this keyboard. Let's say I insert the install disk or the restore disk and hold down C or D, whichever is appropriate. Instead of starting off the disk, it simply reboots.
I also can't zap PRAM because of this nor can I start off an external HD. I have tried a Logitech diNovo keyboard and some goofy iHome keyboard and the same thing occurs.
All my software is updated and I'm using 10.6.3

I've just bought a Mac mini to use as a media centre, and I picked up the Apple wireless keyboard and mouse while I was at it. It wasn't until I got home that I read the "requirements" section on the side of the mouse and keyboard boxes, where it states that an existing keyboard and mouse are needed for setup.
I have a USB mouse, but no keyboard (my other Mac is a MBP), and nowhere to borrow one from (all my friends have laptops).

Yesterday my screen (30" Apple Cinema) started showing symptoms of graphics card failure, jagged lines across the screen. I rebooted my Mac Pro and it was gone. Then it happened again an hour later, this time the machine didn't boot, I get the Apple logo, and then it hangs up and the screen is shifted to left (I get apple logo on left side of the monitor instead of the middle) and jagged lines all over.
So the first thing I tested was using Target Disk Mode, it works. I can access my Mac Pro's internal HD's by TDM from my MacBook Pro. Then I tested single user mode, it does boot, I can't read what's written since the screen is shifted to left, but if I type (without seeing) reboot and hit enter, it reboots. So I assume the single user mode is working.
What else can I try to 100% make sure it's my graphics card that failed and everything else is ok with Mac Pro? I already ordered a graphics card replacement but I wouldn't like to be surprised if the Mac Pro still doesn't boot when the card arrives. It won't boot from Apple Startup DVD either. Same thing happens, gray logo then kernel panic with jagged lines all across the shifted screen.

So I installed osx 10.4 server on a Power Mac G4 (white/blue)
Went throught the setup screens and did a complete reformat / install.
Just boots to the loader screen. (Where the mac face shows, followed by a question mark) and just cycles over and over.
I can put the DVD in at this point and restart the install.. I did go in and check the disk permissions and disk status and both passed.

In my attempt to install Windows XP via Boot Camp, I accidentally inserted an SP1 disc instead of the SP2 disc that I have. The installation proceeded to the point where it does for most who attempt this: the screen where you are prompted to press ENTER. I could not proceed and therefore restarted the iMac and held down the mouse button upon start-up to remove the CD.
HERE IS THE PROBLEM:I can not boot into OS X because the keyboard shortcuts (those that might allow me to select which partition to boot from and/or reset PRAM) seem to be disabled. Instead, a reboot always ends at a black screen with a blinking DOS-esque cursor, or the prompt: "No bootable device -- insert boot disk and press any key."
I have attempted inserting my SP2 disc at this point, to no avail. My keyboard seems to be disabled, as if the SP1 install proceeded just enough to establish itself as the boot drive without drivers for the keyboard. I've tried using all 3 USB ports, disconnecting other USB devices. Oddly, my bluetooth mouse works to eject the CD on reboot...

How do I make this work with a wireless keyboard? Apparently, if it is possible, I don't know how. I had to use a wired keyboard to get it boot to CD and I wanted to enable 64-bit, but holding those buttons down on the included wireless bluetooth keyboard do not work. Is there a way to make it work or should I just use a wired keyboard?

Is a usb keyboard needed to switch between OS X and Windows in bootcamp when holding down the option key, or should the Apple bluetooth wireless keyboard work as well?

When using Boot Camp to boot into Windows, what key on a Windows keyboard do you press to move into Windows? I use the option key on my Mac keyboard which gives the alternative of Windows or Snow Leopard.

I have an Intel iMac that came with a bluetooth keyboard and mouse. There are a variety of options that can be used when you boot the Mac, such as hold down the C key to boot from a CD/DVD, hold down the option key to choose the boot drive, etc. When you have a BT keyboard, it doesn't connect until it is booted. How do you get the iMac to recognize, say, the Option key?

iMac, Mac OS X (10.7.2)

I have a Mac Mini 2006 with Core Duo 1.66Ghz and an 80GB HDD. I use this computer as a Media Centre PC (not really nesecarry information). The 80GB hard drive has died in this machine. I know this because I took the drive out, formatted it, reinstalled it in the mini and attempted to install snow leopard from a boot disk. It gets to about 60% and then throws an error - clearly the drive is about to die.
In my wisdom, I opened the Mini up and replaced the hard drive with a drive from an old (but dead) windows laptop. When I did so and rebooted, I connected a USB keyboard and held down the option key on boot to boot into startup screen (to select the the boot disk I had made). The SL boot disk on a USB key which is recognised when I boot it on another mac. The mini seems not to recognise the keyboard input when holding down the option key. The mac booted straight into Windows which was on the new drive. It booted into the windows "windows did not boot correctly last time, do you want to start up in startup mode?) screen. The keyboard inputs were also not recognized on this screen.
I thought that there may have been an error because windows was on the drive, so I scrubbed the drive and re-installed it as a completely blank drive in the Mini. Again attempted to get to the startup screen and again the same problem. Only this time I am getting a flashing folder with a question mark (meaning the mini cannot detect any bootable drive presumably). The USB stick is flashing, but to me the Mini cannot recognize the keyboard input from the connected keyboard. Could the USB ports have somehow been damaged? Also through this process, I have reset the P-RAM on the mini as well.

My mid 2009 MBP 13 sleeps immediately when it reaches the login screen if the keyboard fails to illuminate, this is also the case when I have actioned automatic login. I know that this won't happen on any occasion when I see the keyboard illuminate.
I have found that if I boot the machine turned upside down the keyboard will almost always illuminate so I won't have the sleep isue. This isn't a practical solution. So I was wondering if anyone could see what was going on based on the logs. This is the most recent failure.
kernal log:

I have Mac Mini 1.66 Intel 2006 OS X 10.4.11 with CD-R and DVD Player that won't boot properly into single user mode using a IBM PC keyboard. I have tried the alt-s, windows key-s and control-s key combinations. from the mac keyboard hints sheet located on this web site.
I have also tried to boot with key combinations from the mac mini manual with no success. I have also tried to simply insert the install CD/DVD for MAC OS X 10.4 that came with the computer and start the computer with various key combinations and the cd/dvd drive will not boot.
What do I need to do to be able to accomplish these tasks with the PC/ Windows keyboard.

I seem to be having problems syncing up the mouse and keyboard on the new iMac with boot-camp. For some reason the keyboard is not working at all, and reinstalling boot-camp drivers does nothing. The mouse is recognised however scrolling does not work.
I had this problem before and downloaded microsoft sidewinder mouse. This solved the problem before, but now it doesn't do anything.
I was wondering if anybody knows exactly what the drivers are called for the keyboard and mouse, and how to get the mouse scrolling working? Also once I get the keyboard synced, how do I change the settings so that (for example) the volume controls work.
This is really confusing me, because I'm pretty sure when I installed Windows the scrolling WAS working, but then when I went back to it (admittedly after linking the formatted drive with Parallels) it simply doesn't work properly.

If I use Target Mode or Boot Camp on my iMac, I need to hold down a key during startup to activate them. But my wireless keyboard doesn't get recognised by the iMac till late on in the startup process, so it doesn't realise I'm holding down the key until way too late, and just boots up normally. Is there a way around this, or do I need a USB keyboard?

I finally went from Leopard to Snow Leopard (SL) by doing a clean install. But I found I was not able to boot from the install disk by the normal procedure -- restarting and pressing the Option or C keys. Before the SL install, I had a volume structure problem on my HD and tried to use the Leopard install DVD to repair the drive. I was unable to do that by using the normal boot up procedure.why I can't boot from the optiical drive by pressing the designated keyboard key(s)?

I did a password reset on my Macbook by using this process:
1. Reboot
2. Hold apple + s down after you hear the chime.
3. When you get text prompt enter in these terminal commands to create a brand new admin account (hitting
return after each line):
mount -uw /
rm /var/db/.AppleSetupDone
reboot
Everything went smoothly and it brought me back to the welcome screen where your supposed to create your account and what not. But went I tried to type into the input fields (name, address, email etc.), it wouldnt type anything. Every time I try to type it would make a noise as if it knows im trying to type but nothing shows up.
Seems as if the keyboard is locked or something. I know that the keyboard works because it worked fine before I did the reset n plus when I reboot hold apple+s, I can type in the terminal just fine. With that being said, does anyone know how to unlock my keyboard?

I have an Intel Mac mini (purchased in 2005 or 2006) with a fresh install of OS X Leopard on it. I recently changed the Startup Disk in the OS X system preferences to be the CD/DVD drive, and everything has gone downhill since there.
I inserted a CD and attempted to boot from it right after changing this setting. I noticed the CD drive spun up the disk, but after waiting several seconds a black screen appeared, saying "No bootable device — insert boot disk and press any key".
There were two problems here: first, the CD never ejected from the computer, and second, there was no response to any key press.
After restarting and shutting down a few times I got the Mac to spit out the CD somehow. I restarted, inserted the same OS X Leopard disk used to install the operating system earlier that day, and got the same "No bootable device" error.

Just partitioned 150gb for bootcamp on my 1TB HDD. I installed XP Media Center OEM without a problem at all. I then put the snow leopard disk in and it autoexec'd and then looked like it was installing stuff. Then it went to screensaver and would not respond to keyboard or mouse input.

I intend to purchase a wired keyboard on my BTO iMac and I understand that there are two USB ports, one on either side of the keyboard. Are these ports USB 2.0 as they are on the rear of the iMac?
