Purple screen on start up
Very strange thing happened within the hour. At one point my keyboard started to type characters in a different language. I shut down computer and restarted. When I restarted a purple screen appeared. To the lower left was a circular arrow. In the middle of the screen was an icon of my Macintosh HD with a small "x" in the corner, on the lower right was an arrow pointing to the right. At first, I couldn't press any of these icons as my cursor was doing the small timer thingy (not beachball). After a couple of minutes, my cursor became the usual mouse arrow. I clicked on the arrow pointing to the right and my computer went to the login screen. I've not yet shut it down and actually I'm afraid to. Anyone know why this might happen and if it is a sign of something wrong?
Thanks-
Dave
HI David,
Sounds like the hard drive needs help. Try booting from your install disk and check for errors.
Restart your Mac while holding down the C key, pressing the power button and inserting your install disk all at the same time. An Installer window will open, but do not proceed with any installations. Instead, from the Menu Bar, select Utilities/Disk Utility. In the Disk Utility window click First Aid, and then click Verify. If Disk Utility reports errors, click Repair. When Disk Utility is finished, from the Menu Bar, select Utilities/Startup Disk. Select MacintoshHD 10.x.x and click Restart.
Troubleshooting Startup and Login Items
If you can, see if you can locate a crash log.
How to locate a crash log:
1. Open Finder.
2. Click "Go" in the menu, then select "Go to Folder".
3. Copy and paste this path into the Finder dialog:
~/Library/Logs/CrashReporter/
4. Click the Go button.
5. Finder opens the folder containing the crash log. Look for a the crash file with a date field that looks like the most recent.

I have bought macbook pro 15" i7, 4gb ram, 500 gb hdd in the month of March year 2011. I have used it just for watching movies, surfing net and writing script on final draft software. Just two week back I started using final cut pro to edit my short film but suddenly the screen of my macbook turns black and it shuts down. After few minutes I pressed the start button but it took lots of time and open with blue-purple screen. It also get heat very soon. I don't know what the problem is. Please help.
Boot from the install DVD and repair the startup drive
Then run hardware test

Ok so this started around a week ago. I got home one afternoon put my phone down went back to it and pressed the home button and it seemed that it turned itself off so I tried turning back on, didn't work so I hooked it up to my laptop tried turning it on again it came on but I got a WHITE screen. So after that I decided to leave it for a bit I went to it after it started working fine...until 4 days later. I was on instagram and all of a sudden the screen starts flickering like crazy and then it turned itself off, I did what i did last time and just left it for a bit it came back on working fine. And then about 2 days ago I was listening to music and the screen froze then started flickering (getting quite annoyed at this stage) and then turned off, this time I tried turning it back on straight away only this time it worked. And that brings us to this morning, i was on facebook and about 5 minutes later it starts flickering and freezing once again and then turned itself off. So i hooked it up to my laptop I then got it to turn on for like 6 seconds then the screen started to dim and turned off. That brings us up to now about 10 minutes ago i tried turning it on, it turned on but I got a PURPLE screen and it just stayed like that until i turned it off. Does anybody have any idea what is going on? I think its the screen itself but i'm probably wrong. All help is appreciated.
I am also having the same problem.. Its too much annoying and its unfortunate nobody at apple support has anyclue of what is happening?
... This is happening almost most of the time keeping my phone down most of the times. -
N8/C7 PURPLE SCREEN ISSUE AND HOW TO SPOT IF YOU H...
MODS THIS IS NOT A POLL OR IN ANYWAY SHAPE OR FORM A VOTING THREAD IT IS A THREAD TO WARN USERS ABOUT THE PURPLE SCREEN ISSUE AND HOW TO SPOT IT IN THEIR PHONES CLEAR AS DAY , I HAVE BEEN INFORMED FROM THE DIRECTOR OF COMUNICATIONS AT NOKIA VIA TWITTER THAT THIS THREAD IS OK AND THE TEST IMAGE IS FINE TO LOAD UP
The following has been added by vandelay (Nokia administrator) :
Please note that there is normally a slight variation in the purple color level in each display
unit. This is related to the display manufacturer's optical tuning process. However, some Nokia C7 and Nokia N8 users seem to be experiencing a
slightly higher level of purple color tint on their device screens.
Nokia Care's technical experts told me that the easiest way to spot this problem is to just look at the black idle screen of the device - if there is a clear purple color tint on the idle screen, you should have the device inspected at a Nokia Care point. They will repair the device the device under warranty if there is a clear defect in the device.
So seeing some purple on the test image does not necessarily mean that your screen is faulty, but we hope that it helps some people to decide whether they should visit a Nokia Care point.
(end of vandelay's addition)
as you may or may not have read many n8s and c7s have a purple tint issue
this can easily be spoted by saving the picture below to your pc , transfering it to your n8/c7 , then viewing the image in your gallery
if the image shows purple squares in some areas then iam afraid you have one of the screens that is showing defects in gradiation of colurs and the greyscale
there are also many n8s out in the wild that dont have this problem , i have 3 n8s , my gfriend has one , hers is perfect and shows the test image with no purple tint at all my three n8s all have purple tint and some display it worse then others
the test image can be viewed on any brightness and it should display just as it does on your monitor screen ,my gfriends n8 displays the image perfect under all brightness levels yet my three n8s show the purple tint heavily on low brightness and not as much on full brightness
the test image can also be viewed via tv out and hdmi out and again if you have a defect screen you will see the image perfect on your tv yet on your n8 screen you will have purple tints
here is the test image for you to load to your device and view via the gallery
as stated above if you have one of the screens with defects in colour gradiation you will see some of the squares as purple
this shouldnt be happending as there n8s out there that display the test image perfectly
from all my research on this in the last month and my time studying ICT systems support in which i have a diploma , it seems clear to me that nokia have used at least two screens in the build of the n8
many phones bought between october launch and december dont have the problem yet there are still some that do but not as many as now , phones bought from the end of december up untill current date seem to have the issue moreand its now nearly impossible to find one without the purple tint issue
this leads me to believe that from the start nokia were using at least two screen in the n8 , then one started to run out around december and by the end of december a huge majority of n8/c7 handsets have the troubles, if not all of them shipped after december
infact ive been to every phone shop in lakeside , chelmsford , colchester which included : carphone warehouse , o2 , vodafone , orange , three , phones4u , tmobile all n8/c7 handsets i asked to look at had the problem not one n8 i looked at didnt have the issue
i have been in contact with nokia care escalation team , all they did is send me very badly refurbed handsets back for my brand new n8s , which across all three handsets had the following faults
#hdmi covers scratched and worn
#no imei number under the hdmi cover on one of them
#torx screws on battery cover very worn
#plastic top caps not fitted right
#one had a huge gap between the silver screen surround and the main chasis of n8
#they all still had purple tint issue
so nokia sent me three refurbed handsets for my brand new n8s , i obvously complained as they were so new i could have taken them back to the shops with the reciept but now nokia had changed the imei numbers my reciept was useless , i said i should be sent three brand new n8s , they again sent me badly refurbed handsets just as bad as the 1st lot and again all three of them had purple screen issues
i complained again and this time supervsior took over the case and agreed that 3 new n8s should be sent to me as mine was so new , she got them sent out and this time they were new but they still have the purple screen issue
thats a toatal 12 n8s direct from nokia and all of them have had the issue so i cant recomend going to a nokia care point or nokia care uk as the refurbs i was sent was a complete joke and looked like they were just used handsets that had been through a rough time
through this month of me talking to nokia and sending emails and getting these phones swapped back to a condition of the phones that i sent them , they have said they are investigating it and taking it seriously however after some of their actions towards users (myself included) on these forums it doesnt seem like they are taking it very serious at all , they have known about it for a month now and we still have not had an offical response from nokia themselves

there are many more threads about this issue across the net and if you google n8 screen problems or n8 purple screen problems you will come acroos many many pages of unhappy users from all across the globe
i just hope nokia sort this out soon
ho do you users with the problem feel about this issue and how do you think nokia should resolve it
id be happy for a screen swap at a nsc or via warranty postal repair as long as it could be done quickly and the user wasnt without their phone for too long after all this is nokias mistake and not the users that bought the phone so all fixes should be at minimal disturbance to them
heres hoping when you test the image your not as unlucky as me and many other n8 owners from across the globe , its a brilliant phone but this screen issue lets it down alot especially during watching films and stuffsorry to hear you guys are having troubles too , its a shame sucha great device as the nokia n8 has had an issue like this arise , it is effecting alot of n8/c7 handsets and is quite a widespread issue across the globe
it would be great to hear from as many users as possible about this and what they think about it as a user of the c7/n8
jimmyireland about your post mate
yes it was written by me and yes it ws deleted not once but 3or4 times actually
the mods said it was because i had set up a poll and voting system , so i read through forum rules and posted it again with what fitted their guidelines and even put in big caps that it was not a poll but a thread to help users identify a problem and discuss it which is what the forum is for , it was deleted again , i then posted it again with just the test image and how to spot the problem and again put big caps that the post fitted their guidelines and was just to help users , it was again deleted and i was banned by mods for 2 days saying that i had broke forum rules and posted a poll and that the test image wasnt a proper test image
i then asked other users to post the image but when they tryed nokias spam filter kicked in with a message saying that their post contained spam and that they should write it again and try posting again
to be honest it really looked like they were trying to cover up the issue , fair enough my 1st post could be considered a very very rough poll but the posts i made afterwards were edited to fit nokias guidelines and they still removed them ad banned me and then other users posts were marked as spam
so i tweeted alot of people and even nokia have said that as long as the post doesnt contain polls/votes then it will be fine to postand that mods shouldnt delete it , which was excellent news and hopefull this thread will stay and users can load the image and test their screens and then discuss the issue here so nokia can see users discussion in one thread , it will alo help awareness of the issue
hence this post that isnt a poll but a thread to help users identify wether their n8/c7 has a screen with a defect in the gradiation of colours
as stated in original post not all n8s have this problem my gfriends doesnt and it displays the test image perfectly on all brightness settings , yet my n8s show the image as very purple on low brightness and the brighter the screen goes the less the purple is shown , it is still there just not as visible as it is in the lower brightness settings
as i also mentioned many n8s between october and mid december are fine although some still have the problem , yet from mid december till current date the amount of n8s with purple issue is much much higher and it now seems very very rare that you will get a brand new n8 from the shops without this screen issue which leads me to believe that from launch nokia have used at least two screens in the builds of the n8 , some great screens and then the ones with dodgy purple tint , from the threads across the web it seems like the good screens nokia were using either run out or they have failed to source the same screen or the manufactuer of the screen has changed something
iam not a nokia hater and iam not here to cause trouble or loose nokia sales etc
i love nokia have used them for years and used symbian since the 6680 , iam always helping users across the web with their nokia problems and am an avid user on nokia users please check my profile and feel free to check my posts and how many times ive been thanked for being helpfull
http://www.nokiausers.net/forum/members/buxz777.html
as you can see i love nokia and spend alot of time using their devices , speaking highly of them and helping their users with problems, i also love good customer services and customer relations
i understand that big companys have build issues iam a gadget lover and trained in ict supprt iam not silly and understand that these things happend and building these phones with such complicated electronics and some could end up with issues , it could happend to anyone , sony , apple , samsung , blackberry , lg etc etc
however its how the companys react to these issues and relate to their customers that have spent 100s of pounds on their devices that is important , issues do arise , its how the company looks after its customers thats important
i think alot of users think the same , they dont expect nokia to click their fingers and go heres a fix but they do expect nokia to investigate the issue and they do expect nokia to relate to its customers and not ignore them or the issue which is what it looks like when posts are deleted and users are banned for posting informative posts that help users identify a problem
things like sending users really bad refurbs for brand new n8s also dont help users confidence in nokia statement of going to nokia care about the problem as all i got was second hand looking n8s that still have the problem they were sent off with and the originals were in much better condition
like i say iam not here to cause trouble and i love nokia the n8 is the best phone ive ever had and its almost my dream device and everything ive wanted on a device for years its the ultimate convergance device and agadget lovers dream , however when you see your gfriends and some of your mates n8 screens display the test image perfect then your n8 display it with a very purple hue it does dissapoint you and you do hope that nokia will take notice and fix the issue with the least amunt of hassle to the users
cheers jimmy and sorry about the long post just wanted to clear some things up
now lets get back to discussing the issue and what other users think about it
have a great evening -

The other day my imac suddently crashed while I was working on it. Upon restart, I received no chime, but did notice the fan was running through open holes on the top.( I could not however, hear the hard drive or anything else)After about a minute of a completely black screen, the monitor turned a deep shade of purple.
I've checked the power, etc... but have had no luck getting the machine to boot or for the purple screen to disappear. I've tried re-starting a few times but get the same scenario over and over...
Is it safe to assume that this is a motherboard issue? Any ideas on salvaging this machine?
thanks

you may be able to open up the bottom and use the Power Management
Unit Reset (button) that is hidden next to the airport wireless card location.
There are a few expensive parts that could also be to blame for this issue;
and a trip to the repair shop for a diagnostic may be warranted.
The PMU reset is a small button; there are some instructions in the service
manual I happen to have a copy of... that won't help you much! I saw in
another post in Discussions, where someone had linked to an XLR8 take-
apart page for the iMacG4, maybe it has this button clearly marked. The
button is rather hard to see once the metal plate is removed from the iMac
and it is small, too. I've not yet had to reset mine; but remember a few
discussions at MFIF referring to that as a cure for some issues.
The PDF service manual page is #108+, for details on PMU location/reset.
The image is most helpful; and the orientation is not mentioned in this
manual I have. Looks like the button has a little picture on or above it
that looks like a tiny battery; you press this ONCE. Twice will do bad.
The little picture is part of a row of small details under a plastic cover,
near the Airport Card slot where the contacts are for that to connect.
Here is a quote from the procedure page of the manual; please note
there are other tests and things not mentioned that a service tech could
perform to better diagnose that machine's problem. [Pg 108-109]
"The PMU Chip"
The PMU (Power Management Unit) is a microcontroller chip that controls all power functions for the computer. The PMU (location shown below) is a computer within a computer. It has memory, software, firmware, I/O, two crystals, and a CPU. Its function is to: • Tell the computer to turn on, turn off, sleep, wake, idle, etc. • Manage system resets from various commands. • Maintain parameter RAM (PRAM). • Manage the real-time clock.
•Important: The PMU is very sensitive and touching the circuitry on the logic board can cause the PMU to crash. If the PMU crashes, the battery life goes from about five years to about two days if the PMU is not reset.
•Refer to the next topic, “Resetting the PMU on the Logic Board” for the procedure. Many system problems can be resolved by resetting the PMU chip. The PMU reset button is located on the right side of the board, refer to the picture (not here.)
"Resetting the PMU on the Logic Board Resetting the PMU"
(Power Management Unit) on the logic board can resolve many system problems. Whenever you have a unit that fails to power up, you should follow this procedure before replacing any modules.
1. Disconnect the power cord.
2. Remove the user access panel from the bottom of the computer. 3. Press the PMU reset switch (shown below) once on the bottom side of the logic board and then proceed to step
3. Do NOT press the PMU reset switch a second time because it could crash the PMU chip.
4. WAIT ten seconds before connecting the power cord and powering the computer on. If the computer powers on, go to the next step.
If the computer does not power on, there is something else wrong with the computer, refer to the symptom/cure, “No Power” in this chapter.
There could be a hardware failure, and if you cannot boot from the
Apple Hardware Test (on supplied CD or boot DVD) you should take
the computer to an authorized Apple service providor for testing, etc.
Best of luck in this; & thanks to Apple for the information posted above. -
Dead Hard Drive and Purple Screen
Hello all.
I recently updated to 10.4.4, by reformating my drive and putting everything on fresh. I then put just the stuff I use back on. Didn't have any problems along the way, till today. I had the computer set to sleep after an hour, and when I got back from lunch I hit the spacebar to wake it up. There was a Solid purple screen, so I waited awhile then hit the reset button. Then it came up with the question mark folder. I started from the OS disc and ran Disk utility, it sees the other drives but not the main one. The drive doesn't make any unusual noise. Any thoughts?Is the drive "grayed out" in DU or just not present?
I then put just the stuff I use back on.
Did this include any system stuff?

Grey Screen at start-up - Troubleshoot harddrive and/or logic board?
Hi everyone. Sorry for the lengthy post, but hopefully you can help me - I've spent a lot of time on the boards already, but hoped you could clarify some things.
The problem is my Powerbook will not get past the grey screen at start-up. It will not boot off the 10.5 install disk and I can't eject the install disk to run the hardware test disk. Removing 3rd party ram, resetting PRAM, NVRAM, attempting to boot in 'safe' mode haven't helped. The harddrive is softly clicking/searching.
So some questions:
1) Is it possible that an interrupted time machine backup will bork the drive to the point where it wont boot? (See back-story below). I wouldn't have thought so, but prove me wrong.
2) Should I be able to boot from the install disk if the harddrive is stuffed?
3) If it is hardware, it's either the logic board or the drive. Is there any way to determine what it is (eg: is it possible to do a remote hardware test?)
Edit: Just tried mounting the drive in target disk mode using an iBook, but it wouldn't mount. Powerbook displays a black screen.
Oh, and I should point out that this is well out of warranty and any fixes would have to be cheap : ). Basically I need to determine if it's the drive or the logic board, preferably without having to buy and install a new drive when it may not be the problem.
Any help or advice would be appreciated.
Cheers
- Ben
Here's the back story if it's any help; recently upgraded to 10.5, created a base install disk image of all installed and registered apps (in the event that my drive failed). Copied data etc from the previous system over. It ran fine for a few days. This morning I ran time machine for the first time, left the computer for a while, came back and the screen was black (as if it was just displaying black, as opposed to off). Thinking it was just a display issue (which I've seen before), I put the system to sleep (power button, then 's'), woke it up again; still black. So I forced a shut down (wouldn't allow me to do a normal shut down, because dialogue boxes must have been preventing it) and on boot I got the grey screen.
-------Hi Ben W. I don't have a good answer for you, but based on your information and what you've done, I think I would try starting the machine after disconnecting the harddrive. That requires taking the top off first, for which instructions are on ifixit.com.
I can conjecture that a blown HD is preventing normal operation, perhaps sucking the power down, disrupting the optical drive, etc. This is purely conjecture, but costs you nothing but your time. If this turns out to be the case, I figure the optical drive should start responding again (hold C key during reboot, etc). -
Issue: One day I unplug the power, the screen freezes and I get frozen music sound. I shut down, start up, I get 3 beeps (1 short 2 long), which indicates a Video failure according to the Thinkpad Laptop beep code list.
How I solve the issue day-to-day: I turn the heat up - I disconnect the battery and hard drive and plug in the power then turn it on. I will wait until the underneath is searing hot with a blanket blocking the fan's flow of air, I mean way hot because any
cooler and it won't start. Plug stuff back in, Hard drive first, Battery second, turn off with power button hold, unplug power, replug power.
I turn it on, no beeps, it goes past the first Lenovo screen, then gives me a prompt because it "didn't shut down properly" and continue regular startup. What happens next is the Windows logo appears,
and just as the animated windows logo starts to move (you see 2 small colored dots on the screen), it freezes. I see this every time, I know naturally that it means that the laptop is still too hot to go past that point, so I shut it down and try again. After
about 5 - 10 tries it will go past the splash screen and into the login area, then it's all fine.
Sometimes when I unplug the power from the back by accident it will freeze. By accident I mean that the connector wiggles it's self out easily. This unplug freezing thing started happening about 1 week before the 3 beep black screen problem started rolling,
so I'm putting 2 together.
Errors:
I got a Blue Screen of Death the first time I started it up with the overheating ritual, but I never got it since. It was 0X7B.
I got another Blue Screen of Death about a week ago, but came as it was on already and I had been using it, and said something about disabling Cache or Shadowing in BIOS. I never got it since.
Event Viewer events found:
1. Kernel-Power, Summary page.
There are critical events for a few things like Kernel-Power, Event ID 41, Task Category (63). There are 19 of them, each day 1 or 2 of them but mostly 1, so this maybe corresponds to my daily ritual.
"The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly."
2. Kernel-Processor-Power - Event ID 37, task category (7)
"The speed of processor 1 in group 0 is being limited by system firmware. The processor has been in this reduced performance state for 71 seconds since the last report."
3. LMS - HCMI - Event ID 2, Task Category: none
"LMS Service cannot connect to HECI driver".
I came across a very sluggish performing control panel for Nvidia before and after this problem, and I tried installing a newer version, which I had to jump through a few hoops to do, like uninstalling first, not just updating. At first it said that the
driver wasnt for the system, which was wrong. I made it work somehow, but it was still sluggish. I rolled it back to an earlier driver, and now it works fine. No sluggish performance / slight freeze window thing going on.
MSCONFIG.exe, Boot Advanced Options: I have tried twice to change this 1 setting, check box "Number of processors" and change to 2 processors, because I do have 2 processors. I have been able to change
this in the past, but it does not save the setting now, and I believe this option was selected before I started having problems, and settings did not disappear then.
What could this be. The small round BIOS battery? The video card like everyone presumes? (I.E. the entire motherboard replacement), Software? The wiggly power input area? (Not enough power getting in?), Firmware of some sort? The BIOS software being wrong?

Screen will start to pixelate and error message appears to restart
I have a iMac G5 17". It will boot up, apple start up screen, Mac OS X screen, and then finally Desktop. but about 20 seconds the screen will start to pixelate and kinda "wig out" then it will tint a dark grey and a error message in multiple languages will appear saying " Push the power button to restart". at this moment the screen is completely frozen. all I can do it power it off.
What could this be? Maybe a bad hard drive? Screen? Power source?Hi...
Better to post your topic in the iMac G5 (PowerPC) community here > iMac (PPC): Desktop Computers: Apple Support Communities
This is the iMac (Intel) community. -
My old 17" MBP (2005) often crashes, freezes or shows grey screen at start up. Also track pad often does not work. I have re fomatted the HD and reinstalled system but to no avail. Genius bar says possible faulty HD, but I suspect logic board. All checks out OK on the Apple Diagnostic bench. Can a Logic board go intermittant?? Any Ideas any body??
Ive repaired 1000s of laptops over the years (translate: diagnose and replace parts).
Its not that old, Ive owned 100s of laptops (most were free) ....some I still have are nearly 13 years old and still perfect, ....some extremely expensive ones died in under a year.
other than becoming obsolete at some point, there isnt really any "will spoil on" data like Milk for solid state computer parts, ....alas.
You can have a $5000 laptop die in 4 months, and a junker one keep kicking after 10 years.... Ive seen that firsthand countless times.
Common logic dictates that "very expensive = long life" in computers,..... but all the repair people will tell you just the opposite.
I know you have a gripe, I get that all too well honestly . -
IMac will not boot up/purple screen
Hello people,
We've got a newer 27" iMac bought in 2010. Anyhow, yesterday we experienced a power outage. We installed a surge protector on the house but it didn't do our iMac any good. The iMac will cut on but goes to a purple screen only showing the speechless box. We can't get it to do anything else besides moving the courser. Does anyone any ideas as to what is going on and how to correct it?
Thanks in advance for and help or advice,
RayLook in your owners manual, it has instructions on what to do if your machine doesn't boot.

I have been requesting help for this for the past HOUR. Firefox is placing ads on my screen at start-up (and they remain there) to get firefox on Android (I don't have a cell phone that uses it), and to go to the firefox site with information on how to use..........I have used firefox for years.........don't need this, and when I go there since it seems to be forced on me, read what is new, and try to close out...........it is back again when I open firefox again. If I keep getting ads from firefox, I will change to another browser!
Firefox 4+ versions use a new build-in home page named <b>about:home</b> with a Google search bar on it (no internet access needed to load that page).<br />
That about:home page only shows some snippets and has a button to restore the previous session if applicable.
If you want a home page without the Restore Previous Session button and the snippets then set another page as the home page like www.google.com used in Firefox 3 versions.
You may be seeing a similar ad on the Google site to install Google Chrome.<br />
In that case use the close X on that ad to close that pop-up and it should stay away unless local storage gets cleared. -
I'm getting the grey screen during start up and can't boot the computer - MacBook Pro with lion.
I did a command r after doing some research but got nervous that it would automatically wipe my hard drive and reinstall OS.
I was nervous because it asked me for language for software use before any options were presented (such as repair via disk utility). It looked similar to an OS install.So I powered off....Is there a risk at command r will result in wiped HD without me actively making that choice?Repair the Hard Drive and Permissions - Mavericks, Lion/Mountain Lion
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu. Select Restart from the Apple menu.
Reinstall Mountain Lion or Mavericks
OS X Mavericks- Reinstall OS X
OS X Mountain Lion- Reinstall OS X
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is
three times faster than wireless. -
Why is my G5 is stopping on the grey+apple logo screen when starting up?
My G5 is stopping on the grey+apple logo screen when starting up and fans run faster than usual after a couple minutes. I have read many of the posts related here, but it seems none are exactly what I am experiencing. Here is what I have done:
+Disconnected all peripheral devices (except for keyboard and mouse).
+Unplugged power cord and plugged back in.
+Unplugged ethernet cable.
+Removed added memory.
+Reset the SMU button on the logic board.
+Reset the PRAM by pressing Command-Option-P-R keys. It makes its second start up chime but I still get the grey screen.
+After opening the disc door with a paper clip, started up while pressing "C" with Hardware Test CD which found no problems.
+However, also started up with Systemworks disc and ran Disc Doctor, but I get an "unexpected problem, Error found: disk error" while "Checking Directories: Catalog Structure". When trying to run Speed Disc, my hard drive doesn't even show up in the window to select it. Nor does it show up in Disk Viewer.
I have not tried to start up from the original Mac Startup or installation disc that came with the computer. I am not at my G5 right now (having to use the internet at work). If I start up with that disc, will I loose any work (if I haven't already) that I haven't backed up?
Also, the G5 manual suggests replacing the lithium battery inside the tower if I am having problems starting up. I have not read to do this anywhere else except in the manual. It mentions having problems with the date and time which I haven't so I doubt it's the battery.
Any suggestions?
Thanks,
Tony
G5 Power Mac Mac OS X (10.0.x)First and foremost you should never use Norton Utilities Disk Doctor or Speed Disk. They will corrupt your hard drive. NUM is not compatible with modern Macs and is no longer supported by Symantec. I highly recommend you uninstall it. You will find instructions here.
You should do the following:
Boot from your Tiger DVD. After the installer loads select your language and click on the Continue button, then select Disk Utility from the Utilities menu . After DU loads select your OS X volume from the list on the left, click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer. Now shutdown the computer for a couple of minutes and then restart normally.
If DU reports errors it cannot fix, then you will need Disk Warrior (3.0.3 for Tiger) and/or TechTool Pro (4.1.1 for Tiger) to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
If this does not fix the problem, then it's possible your system files have been damaged in which case you may need to reinstall OS X. You can do this by an Archive and Install which does not require erasing the hard drive. However, the hard drive must be verified as OK per the preceeding intructions.

In your opinion, Apple, what is the best way to display Executive dashboards using the IPad? Our company purchased IPads in hopes that they would be able to display the our Web-based Dashboards, but they cannot. The dashboards render fine in the Safa
