Slide navigator in keynote blacked out and locked - how do I access it again?

Opened a presentation in keynote and have obviously tapped something as have locked the slide navigator bar on the left side somehow! It's currently blacked out and I can't access the slides or move it to access the key buttons underneath it so am stuck on the presentation I have open. Help!?

If you forgot (or don't know) your passcode, restore the device from backup on the last computer it was synced with when the passcode was turned on... this will remove the passcode. If you do not have access to the last computer it was synced with, you will have to force it into recovery mode & restore as a new device.

Safari is showing everything greyed out and locked, how do I change that?

I'm having a problem where Safari periodically locks and greys the screen. It wil continue to update / refresh but I can't inter act with it. The onjly way I've been ab l to clear this is to reset my ipad. Obviously dont want to keep doing that all the time. Top of screen shows a closed padlock. Not sure why or how it got there. Ideas??

Try clearing Safari's cache : Settings > Safari > Clear Cache (and Clear History)
If that doesn't work then try closing Safari completely and then re-open it : from the home screen (i.e. not with Safari 'open' on-screen) double-click the home button to bring up the taskbar, then press and hold any of the apps on the taskbar for a couple of seconds or so until they start shaking, then press the '-' in the top left of the Safari app to close it, and touch any part of the screen above the taskbar so as to stop the shaking and close the taskbar.
A third option is a reset : press and hold both the sleep and home buttons for about 10 to 15 seconds (ignore the red slider), after which the Apple logo should appear - you won't lose any content, it's the iPad equivalent of a reboot.
The padlock symbol means that you've got rotation lock on. Depending on what you've got Settings > General > Use Side Switch To set to (rotation lock or mute notifications), then you can lock the rotation by the switch on the right hand side of the iPad, or via the taskbar : double-click the home button; slide from the left; and it's the icon far left; press home again to exit the taskbar. The function that isn't on the side switch is set via the taskbar instead : http://support.apple.com/kb/HT4085

Solution for a course going to a black screen and locking up after a while (20-30 slides for me)?

The LMS is Saba and I'm using Captivate 6. I am testing the course in production. The course goes to a black screen and locks up. The first time was at slide 28 of 55 which is a widget and the second time was at slide 20 of 55 which is a multiple choice test item. I'm not sure if the type of slide I'm trying to advance to matters but I want to give as much info as possible. The issue seems to be random since I was first able to get to slide 28.

With LMS issues you should always test the same project in SCORM Cloud before you blame the project. If SCORM Cloud shows the same issue, fine, blame the project. If SCORM Cloud has no issue with it, get in touch with the LMS vendor. It may be that they need to update some component of their SCORM Player software.

Screen problems - black screen and lock-up (plus HDMI issues)

Hi, I'm not sure if these are related to the same fundamental issue, but they are both serious problems that need resolution.
I have a new mid-2012 MBPretina. I am on all the latest updates (10.8.2).
The first problem is the most recent, and the most serious problem. Since I updated the Java a couple of days ago I've been experiencing random black screens and lock-ups. Essentially, what happens is that sometimes when I perform an action (opening an app, clicking a link on a webpage, performing other kinds of in-app actions, etc.) the computer screen will go black. About half the time I can, through my own memory, try keyboard combinations to quit or force quit the most recently used app (the one where the action was just performed), and I will get some glimpse of the underlying apps, while the menubar and other areas will remain black until I move a window on top of the black space. Sometimes no key combinations work and I am forced to perform a hard restart with the power button. This is a serious issue, obviously, since I will lose current work/progress in my apps. I'm not sure if this is because of the new Java update, or has to do with something else, but it started happening shortly thereafter, over the last 2 days. I work most of my waking day on my laptop, and this "black screen of death" has happened about 5 or 6 times a day.
The second problem I have been experiencing since I starting using my MBPr with external HDMI displays in August/September. The problem is that I will plug the MBPr into an HDMI display, the screen will temporaliy go black, and then bring me to the login screen (as if it's crashing, albeit softly). This happens about 1 out of 4 times nowadays.
How can I fix these problems, especially the first?

UPDATE:
Clearly there's a problem because a third of the way through a clean reinstallation from scratch it black screened again. Hmmmm.
Now this is not good. Problem is I can't rule out potential updates from Apple that might have caused this either.
The search for solutions continues.

Can somebody please help? My new iPad (3) has been blacking out and restarting every min...

Ok so before i went on a vacation, i switched off my iPad that's left with 24% battery.
2 days later, i switched it on and the screen just freezes. So i pressed the home and lock button together and reset it.
After this, for every min i used, the iPad just black out and restarted on its own.
It probably restarted for more than 100 times already and i can't restore it or whatever since its just keep disconnecting from my iTunes.
I shut it down, reset it, close all the apps, none help.
Does anybody know a solution to this?
Please help.
Thanks a million

How do I fix my messages if I sent a REALLY long message to someone and the messages just blacked out and won't open to show my conversations or anything?

I sent my friend a really long message of moons and spaces to **** her off for fun, and my messages froze, blacked out, and now they're blank and I can't click anything. I did it before on another day, and this never happened. Is this because the messages are still sending? Can I just backup and wipe my phone to fix it?
I need help ASAP I need my phone.

Sounds as though the messages app has crashed. Follow the below steps:
1. Double tap the home button, locate the messages app in the screen that appears and swipe up to force close it (assuming you're running iOS 7 on your device).
2. If the above doesn't work, then press and hold both the lock (on/off) switch and the home button at the same time, until the display turns blank, and the apple logo appears. Once the logo appears, release the buttons and wait for your device to power back on.
If neither of the above work, you may well need to complete a restore on your phone via iTunes.

MacBook Pro blacked out/disk locked

Hello and thank you for reading this. I really have no idea what to do next, as I think I have exausted most options.
My Macbook Pro recently blacked out and I haven't been able to get it to boot/load (?) for several days now. It just stays in the grey screen with the apple on it and flickering wheel, and won't go beyond that. I installed Lion on it a couple of weeks ago.
I bought it in September 2009, and have had it updated every time I have been prompted to do so.
My only concern is that I have been eating away the memory with various media.
After reading some posts here about how to do a recovery, I tried the following:
I have been able to get into Disk Utilities and Mac OS X Installer, but I am not getting anywhere with the choices.
When I try to re-install Lion, it tells me my disk is locked, and I can't go any further.
When I try to restore the system with my Time Machine back-up (USB 1terabyte external hd), it goes as far as 'Select Destination' and brings up a screen saying 'Searching for disks...' but nothing comes, most probably because my Mac HD is locked.
I performed a 'disk repair' in Disk Utilities. The first time it said that it could not be repaired in bold red letters. I tried it again today, and this time it said the disk was repaired successfully in green letters. But, it did not give me the option to restart, so I did so after quitting Disk Utilities. Back to square one!! Same grey screen as I had before. I don't know what else to do...
I am now using my old Macbook.
I will attach pictures of the various screens in my next post if it helps.

Ok, so I tried the Safe Boot, and a grey progress bar appeared. After it filled, it disappeared and left me with the same grey screen as always. I left it going like that for ten minutes, and then gave up.
I have just booted though the Power/Option key and selected my Time Machine Back-up disk. Through there, I clicked on Disk Utility and tried to erase my Macintosh HD.
I wasn't sure which format to select, so I went with the default, which is Mac OS Extended (Journaled).
It brought up a message:
Volume Erase failed
Volume Erase failed with the error:
File system formatter failed.
I could only press 'OK'. I then tried to do same format, but with encryption. Same sort of message.
Just tried to do a Restore using Time Machine Backup as the Source, and Macintosh HD as the Destination, but again, this message popped up:
Restore Failure
Not enough space on /dev/disk0s2 to restore
So, I think my luck has finally run out...

I like and use Top Sites but it has become unsuable with this constant blacking out and reloading the thumbnails. My MBP has not seen a problem at all.
I have been searching every other day for over a month trying to find a fix in Windows Safari with no joy. I want to resolve, not switch browsers. Please offer up a solution that only refreshes the Top Site thumbnails once a day or as some controlable interval. Started about two versions ago, now on ver 5.1.5. Windows 7 64bit.
Safari 5.1.5 for Win64 bit, Windows 7!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I think I solved the wifi connection problem, just by switching off completely the router! sounds trivial, but in this case it worked!!!
the funny behaviour of the trackpad/cursor still persists. any suggestion???
thanks again

Why does my Macbook Pro Suddenly will suddenly black out and freeze I can't do anything and I am always forced to force off my mac.

This always happens to me but recently it's happens more and more. Sometimes When I use it to game or do work or skype it will eventually black out and forze. I always have to hold my power button down to force off my Macbook pro. What is the caused of the proble and will focing off my macbook constantly spoil my mac?

In very rare cases resetting SMC has solved this problem.

Screen blacking out and freezing when phone is charging

I have noticed sometimes my phone is blacking out and the only way to get the screen to come back up is to remove my battery. It happens about 2 or 3 times a day. Also, when charging my phone I will press an app or phone number and it goes to a completely different app or contact. Does anyone know how to fix this?

ive had an issue similar to this. my music worked for about a month then kept freezing on me. it wouldnt go back to the main screen or anything in the music player the screen just went black and my phone completely froze. however a hard reset worked for me. when you have an issue like this that can be resolved any other way this fixes it however i would use it as a last resort as a factory direct reset erases everything even backed up information on your sd card because everything is reset to the way when you first bought it out of the store. if you think this will work for you here is the quickest and easiet way i have found to do it:
turn droid 2 off
open keyboard and press x while holding the power button
device will power on
keep holding until a yello triangle appears
press the magnifying glass on your keyboard
use the volume button to select wipe data/ factory reset
use camera key to confirm
tap wipe data/factory reset
then ok
highlight reboot system now
then ok

Firefox 4 blacks out and distorts sections of the screen if I scroll on a website, navigate the bookmarks or sometimes just randomly.

Firefox 4 blacks out and distorts sections of the screen if I scroll on a website, navigate the bookmarks, at the addons/extensions menu or sometimes just randomly. Occasionally this causes it to crash often with the rest of the computer (no crash report). The previous versions of firefox all ran fine.

I seem to have fixed this by setting layers.acceleration.disabled to true (In about:config). I assume this is something to do with graphics hardware acceleration but I am not sure what the wider consequences of changing this setting are. Nothing seems to be going wrong so far though.

My Macbook "blacks out" and then turns back on?

There are times when my MacBook will "turn off" or "black out" and then after a few seconds, it would just turn on again with all the applications I was opening opened up already. Please help? This has happened 3 times now. :/

Looks like you have a 2010 Macbook. Are you running 10..6 Snow Leopard? Things to check. Go to system preferences/energy saver/ schedule and make sure nothing is checked. Also uncheck put hard drive to sleep. Do a pram reset/Command/Option?P/R and hold power button down for three chimes. You could also reset SMC. Hold down the Command?Option?Shift while holding down the power button for about 10 second. You should be able to access the apple hardware test by starting up and holding down the D or Option D on startup. Run the test. If not and you have the install disks you can run it from there by inserting it and doing the same thing. Use disk utilities in the utilities folder to repair disk permissions and verify your hard drive. If it needs repair ,you'll need to use the install disk to do it under utilities at the top of the screen. If you have a newer operating system ,Then the only way to do this is through the restore partition by starting up and holding down the option or option r.You could look in your library system fold logs and see if you see anything under crach report that says thermal. Let me know.

My screen blacks out and computer starts up again due to an error. Anyone any suggestions what could case this?

Hello nattygrimm,
I was looking into the issue you are describing and found a great resource to try and fix the issue without having to re install the OS. It is an article called Mac OS X: How to troubleshoot a software issue found here: http://support.apple.com/kb/HT1199.
I recommend starting here:
The first and easiest test to try is to see if the issue affects a different user account on your Mac. Each user account has customized preferences and other items stored in its home directory. You'll first need to create an additional user if one does not already exist (follow steps a-h below). Then, log out of the current user and test the issue in the new user account.
If this resolves the issue, there may be an issue with a file in the home directory of the original user account.
From the Apple menu, choose System Preferences.
From the View menu, choose Accounts (or choose Users if using Mac OS X v10.2 or earlier).
Click "+" (or click New User if using Mac OS X v10.2 or earlier).
Give the new user a name and short name.
Mac OS X v10.3 or earlier only: Click the Password tab, and give the user a password.
Mac OS X v10.3 or earlier only: Click Security.
Select the checkbox for "Allow user to administer this computer". This makes the user account an administrator.
Click OK, or quit System Preferences.
Work your way down the article as needed.
All the best,
Sterling
