OS X :: IMac Login/Keyboard Malfunction?

Oct 6, 2009

I have a Mac OS X (silver iMac) and starting this morning it will not let me login to my account, which is the single and only account, and the admin. I shut it down last night as usual, and it did so just fine, and it boots up the same as well.

My keyboard, however, is screwing up. Buttons like the "return", "shift" and "control" apparently count as characters, and since my password is a series of dots I can't tell how it's malfunctioning. I can't login at all.

I've tried restarting the computer several times, unplugging it and replugging it, and changing which USB port the keyboard was plugged into. I've also tried typing one key over, on both sides, just to see if it would work. I have no idea what's wrong here - does my computer have some sort of virus? Or is it my keyboard? Is there any way I can reset my computer, or just manage to login? I'm really stressed out here, and willing to listen to anything.

MacBook Pro :: Trackpad And Keyboard Start To Malfunction

Jun 17, 2014

I have been having a number of issues with my unibody MBP for a few months now. I find that after using it for a while, the trackpad and keyboard start to malfunction. So far I have cleaned the hardware as there appeared to be some dust and debris between the internal battery and trackpad, but unfortunately this has not fixed the problem. I have also discounted any software issues, having cleared the hard drive back to stock.  

From further research I have seen that the batteries can swell (design defect?) and cause these issues. It seems to occur when the hardware gets warm during use, and having looked at the battery, it is slightly swollen and misshapen.  

As it appears to be a manufacturing/design defect, is it possible for Apple to replace the battery? Unfortunately I'm not located close to an Apple Store.

IMac (Intel) :: Unable To Login / Bluetooth Keyboard Not Working

Jun 23, 2014

My iMac recently shows a "low battery" warning on the keyboard batteries. 

The iMac's hard drive had just been fixed by a shop and the OS re-installed. To my surprise I didn't need to do anything to get it to recognize both bluetooth keyboard and mouse - it just worked! Wow. 

Until yesterday. I took out the keyboard batteries, charged them, and put them back in.  

Now I get the login prompt where I have to enter a password. The only problem is, I can't enter a password without a keyboard! And it doesn't recognize the keyboard.  

I tested the keyboard with my MacBook Pro - it works just fine. So I believe that somehow the iMac thinks it's still paired with the keyboard, while the keyboard knows nothing about this. And between those two things it doesn't work. 

I restarted multiple times, and tried to start from another partition by holding down option - the problem is the iMac doesn't recognize the keyboard at startup either.

IMac :: AirPort Malfunction After Waking Up From Sleep Mode?

Nov 5, 2009

The AirPort on my new iMac 21.5'' 4670 is having problems these past couple of days. Every time I put the machine to Sleep and wake it up again, the AirPort cannot find any network. My wireless is fine and there are other wireless networks the machine can detect when it functions well. I have to restart the computer to have the AirPort work properly again. I thought it was a temporary issue, but after repeating a couple of times, it seems to be very easily recreated. And sometimes the AirPort does not function even from a restart. I have to restart another time to have it work.

Does anybody else have the similar problem? I hope it's just a software problem that will be addressed in 10.6.2.

(I posted here because it never happened on my other Macs before.)

MacBook :: How To Login If Keyboard Not Working

Oct 19, 2010

About a month ago, I accidentally spilled water all over my MacBook's keyboard, the mac was turned on, and I notices the keyboard wasn't working correctly; one time before that, I was taking a bath and I had my macbook in the bathroom for music, when I went out and tried to use it, the letter "p" on the keyboard wasn't working correctly, I just turned it off and a couple hours after it was working perfectly!

So I did the same thing this time, let it dry for some hours, and it didn't worked, then let it dry for several days and it still doesn't work! So I removed some keys and try to clean the keyboard with comp air and it didn't worked still. I want to know if there's a way i could log in to my macbook without having to type in the password, like using a remote keyboard or something, please, i love my macbook and i really need to use it for homework! (I study high school and need to record edit, etc music,videos and pics!)

OS X :: Keyboard Shortcut For Login Window??

Oct 9, 2006

Does anyone know of a keyboard shortcut to go to the Login Window (fast user switching) like the Win+L combination for Windows XP?

Or perhaps a keyboard shortcut to lock the machine, like CTRL+ALT+DEL for Windows 2000/XP?

I've been searching for what seems like hours, and I can't find anything.

Mac Pro :: Bluetooth Keyboard Not Sync - Cannot Login

Jul 1, 2008

I've been away for a while, and just started up my MacPro to create a DVD for my customer, and the keyboard (bluetooth) is not responsive. So, I can't log in! I don't have a USB keyboard laying around. So I can't get into the system. Does anyone know a way to get the MacPro to open the disk bay and boot off the DVD? I should then be able to tie the keyboard back to the system?

OS X :: Using Bluetooth Keyboard At Login Screen

May 2, 2010

My MacBook Pro's keyboard just went dead after I dropped it () and now I can't log into the machine to try and salvage it. I for some reason can't get the MacBook Pro to recognize the Apple Wireless Keyboard I have. I had it paired with an iMac but I've unpaired it since and my MacBook Pro won't find it so I can use it at the login screen. I have bluetooth turned off in my account but hopefully that doesn't carry over into the login screen. Any ideas other than buying a wired USB keyboard just to log in so I can turn on bluetooth? It's an early 2006 2 GHz Core Duo MacBook Pro for what it's worth.

Mac Pro :: 2014 USB Keyboard Not Working For Login

Jun 27, 2014

I have a Mac Pro 2014 with two thunderbolt displays and an apple USB keyboard.  Whenever I boot up the computer the keyboard doesn't seem to work at first.  Often I get hung up on the log-in screen pushing keys to no effect until the bluetooth keyboard dialog comes up.  Then after that sits fruitlessly looking for a non-existent keyboard for about 30sec the USB keyboard will start to work.  In total I'd say this delays logging in by about a minute.  During this whole time the USB mouse and Wacom tablet work.  After logging in everything works fine. 

Also this might be related, if the computer goes to sleep it can take several attempts to wake it up before I'll get a login screen.

MacBook :: Keyboard Not Responding So Unable To Login

Dec 22, 2009

I have a first gen 13 inch MacBook aluminum. It was dropped on the corner a few months ago but has preformed fine ever since. I have been using it up until yesterday without a problem. Although yesterday I noticed the airport wireless icon was reporting and exclamation point icon and it was having trouble finding and connecting to networks my iPhone was connecting without a problem. Today I boot up and the boot time is very slow and sometimes hangs.

It takes 10 minutes to get to the login screen and when it does I can move the mouse but the keyboard won't respond. So I can't type my password to login. The mouse moves but when I click a button nothing happens. I booted in safe mode and off the os x disk with the same issue. However I used key commands to do that and selected a boot disk using the keyboard and the mouse to do that so I know the work. Can I bypass my loginscreen somehow? I'm most concerned about my data and I plane to get a hard drive first thing tomorrow.

MacBook Pro :: Keyboard In Login Screen Not Working?

Jun 21, 2012

I just received a 13inch MBP i7. I setup a user account during the installation. Everything worked good until I logged out. Now, when in the login screen after a reboot, the keyboard does not respond (can't enter my password). 

I know it is not a hardware issue as I can type fine when logging into my Guest Account. 

Here is what I tried to fix this: 

- reset NVRAM
- Disk Repair
- Repair Permissions

MacBook Pro :: Mbp Is Makin Harddisk Malfunction?

Sep 2, 2009

I baught a refurbished mbp a year ago... The keyboard lights were not working, so I took it to a mac store. I live in kuwait so there arnt any official mac stores just authorised reslellers (who btw are rippin peopl off with profits over 100%) anyway so they told me that the hard disk was not working!

I told them that I just baught the mbp and it has to be working! They fixed it or something and returned it to me with no charges.A year later my mbp decided to use the malfunction card it stoped working. All I'd get when I turn it on is a white blank screen and a mouse cursor.I took it to a shop to fix it. He told me the hard disk isn't wokring and cannot be fixed. He replaced it.A month later instead of a blank screen I get a blinking folder. I take it back to the shop and he says the new hard disk malfunctioned again, so he replaced it.week later blank screen I take it to the shop same problem hard disk needs to be replaced.Keep in mind that by shop I mean multiple mac associated and non mac shops, I took many opinions b4 accepting that my harddisks and the info on them were indeed lost.Now I am thinkin my mbp is causing the hard disks to malfunction! Is that posible?

MacBook Pro :: Mail Malfunction On It And Desktops

Mar 24, 2012

My wife and I both have had a mail problem that has come up intermitantly for over a year. It's happened on both Snow Leopard and Lion; on our desktop, my MB Pro, and my wife's MB Air. About once a week our mail server (AOL) rejects the password, giving the following message:We use the correct passwords, but it keeps rejecting, with this error message continually popping up. When this happens, I go to Aol.com and check my mail. The password always works, and the messages are all there. So there's nothing inherently wrong with our web mail accounts, and our passwords are right.Sometimes the problem will last a few minutes, other times several hours. And then, for no apparent reason, we open our Mac Mail app again, and it works just fine.

App Store :: Unknown Error (4) Malfunction

Jun 13, 2012

I recently got hired into a Tech position and inherited the current iMac machine running Mac OS X Lion 10.7.3 (now updated to .4 build). I was in the process of De-Personalizing the machine from the previous person who worked in this office, but when I proceeded to try and install some important updates for Final Cut X and entered my Apple ID and Password, I was given an Unknown Error dialog box. Hitting OK I then noticed the 'Unknown Error (4), please try again later' dialog box. This is rather frustrating. 

I was wondering if the reason it is not working is because the versions of the programs where purchased under a different Apple ID (the previous employee who worked here).

OS X :: Switched To Dvorak Keyboard But Login Window Remains QWERTY?

May 11, 2010

I have recently gone cold turkey on QWERTY in favour of the Dvorak keyboard layout, to see if it's really all that it's cracked up to be. However one thing really bugs me, and that is when entering my password in the log-in window, the keyboard remains in QWERTY mode. This is especially annoying because I have actually switched the keycaps on my keyboard to the Dvorak format, so I have to rely on my muscle memory to type my password in QWERTY when I'm logging in after a restart.

Does anyone know how to fix this so that the log-in window is in Dvorak format as well? I am the only user of this computer, so if a fix exists that applies to all users, well, that doesn't matter - as long as I can still undo it later on if I decide QWERTY is better after all. (basically, I want to make the Dvorak layout a system-level default rather than just a user-level default)

Applications :: Dashboard Convert - Currency Malfunction?

Basically, it doesn't convert to the right number... It even gives me different values when I put in the same currency on both sides of the equal sign.

OS X :: HD Malfunction: Invalid Node Structure / 'Sibling Error'?

Mar 12, 2009

Two days ago my MacBook (OSX10.4) crashed; VLC player froze when I was watching a tv show. I though 'no biggie, happens now and then' and hard-resetted my 'book. Tried opening the file again with Quicktime, again, computer froze up. Waited a couple of minutes, hard-resetted my laptop again. Only this time, the screen got stuck on grey/lightblue-ish screen during boot-up.

Tried a lot but couldn't get my MacBook up and running again. Started up with the OSX cd popped in and went to Disc Utility. Mac then told me there was a 'Invalid Node Structure' and that 'The volume could not be repaired'. During a third or fourth start-up this changed to Mac saying there was a'sibling error'.

I checked some sources online, figured out this should be something fixable. One possible option was Disk Warrior. Supposed to be *the* tool with problems like these. I replaced my malfunctioning HD, put an old HD in my MacBook, reinstalled OSX and put the malfunctioning HD in a stand-alone case and connected it too my MacBook. As we speak DW is busy rebuilding the directory but it has been doing so for over a day now. I've read online that it can take a couple of days though. My HD is 250Gb with 30Gb empty space when it went kaput.

Now, there seem to be a couple of other alternative options. These lads talk about Tech Tool Pro - apparantly some other program that could help: [URL]

Then there's a couple suggestions/methods mentioned online that either involve booting up in single-user mode and type some code [URL]

Has anyone ever had their HD act up like this? Any experience/recommendations regarding the programs/methods mentioned above? I'm pretty new with Mac (used PCs for ages, switched to Mac quite recently) and I'm kinda at wit's end here :/. I was in the process of backing up my stuff, but there's a boatload of data on that HD that I hadn't archive yet.

MacBook Pro :: What To Do With A Hardware Malfunction Logic Board And No Parts Manufactured Anymore

Jun 14, 2012

Anyone having trouble with Hardware replacement due to stop of manufacturing?I went to the one and only Apple Store in Hong Kong today and after they have checked my Macbook Pro which I bought in 2007. They said my logic board is malfunctioning and there are no spare parts anymore, also there will be no parts manufactured of the Logic board for my Macbook Pro.So due to Apple's policy I am doomed to buy a new lap top as there is simply no parts to fix this Hardware problem What can I do? I expect to have bought a good product but eventually due to a Hardware problem I am stuck and FORCED to buy a new lap top. I really feel up set as I don't have any options offered besides a Apple Care plan!! But that's useless when I don't have a good running Apple Macbook right ?

IMac :: Keyboard Usb Extension - Compatible Of Aluminum Keyboard?

Mar 11, 2009

My desk configuration for my imac includes a keyboard tray. I am contemplating just not using it, however it really does put the keyboard in a more natural place for me to sit correctly. If I want to use the wired keyboard though, I will obviously need some type of usb extension. I have read these came with the old keyboards, but they don't come with the new ones. Does anyone know where I can find one that is compatible with the aluminum keyboard? Would the extenders that came with the old Mac keyboards work (in case i can find one on ebay or something)?

IMac :: IMac's Keyboard Can Be MacBook Pro's Keyboard?

Oct 29, 2009

This is an idea that I have since I bought a MacBook Pro and it's because I love the trackpad and I use it instead of the mouse.

So the keyboard of an iMac can have integrated the keyboard itself + the trackpad in just a single "device".

The place of the trackpad can be where before were a numeric keypad. It can have the other features that have the MBP's keyboard.
