Screen (iMac) resets to brightest on reboot
I noticed on two iMacs (an 2006 white iMac and a more recent aluminum/glass) that when the screen brightness is set to 0 (dimmest), it reverts to the brightest level after turning it off and then back on. I do not believe this was a problem until the 10.5.9 update, and the problem still exists in 10.6.1 (even after performing a clean install).
Is there any chance that this problem will get fixed any time soon? I'd rather leave my screen on 0 rather than 1, because (IMO) it is brighter than it needs to be even at 0.
Hello Mac OS XP,
this bug came with Snow Leopard.
Do not adjust the brightness slider to the very left end, but just a little bit more to the right.
This will keep the brightness even after restart.

Help. My iPad email screen went blank. I have rebooted, reset and deleted and reinstalled my email accounts to no avail. Any other suggestions?
Restore from iTunes. It is hard to say if you want to backup or rather revert to an old backup. I would recommend to save the previous backups to a safe place and then backup the current state and later test the backups incase your iPhone comes back to proper life.

Have a Droid Razr M that is stuck in the reboot screen. I tried a hard reboot and a factory reset, and it still gets stuck in the reboot screen. How long should I wait for the reboot to occur until it starts back up? I tried the steps for a factory reset given on this site, but it still does not want to work. Any help would be greatly appreciated.
Hello otter314!
Let's take a look into this to see if we can figure out what happened. When did this begin? What's the software version of the device? Do you remember what was happening with the device right before this started? Please supply me with some additional information, I'm happy to help with a resolution!

Currently my iMac has a lot of trouble booting up. Every time it launches it seems to be installing an update (progress bar below the apple sign). It will get halfway and reset itself, or get halfway and go to grey screen then reset itself or just hang on the grey screen.
I can sometimes get it to go to recovery (still has progress bar but gets all the way to 100%). From there I've been able to reset and get in normally. But while operating it will randomly reset itself and the process begins again. I've been though the loop twice. On the first pass I repaired the HD and on the second I reinstalled Yosemite.
Resets have occurred while the computer has sat idle and while web-browsing. The second reset occurred while streaming some video and before resetting it just went to black screen and looped the last second of audio like a CD skipping.
The iMac was partitioned a while back for Bootcamp but has since been restored.
I have noticed the progress bar on boot up for some months but assumed this was a new OS feature.
Any ideas about what to check next would be most appreciated.The progress bar during startup in Yosemite is normal. It replaces the old spinning gear.
Try these in order testing your system after each to see if it's back to normal:
1. a. Resetting your Mac's PRAM and NVRAM
b. Intel-based Macs: Resetting the System Management Controller (SMC)
2. Restart the computer in Safe Mode, then restart again, normally. If this doesn't help, then:
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the Utilities 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.
3. Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the Utilities menu. Repair the Hard Drive and Permissions as follows.
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 click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
4. Reinstall Yosemite: Reboot from the Recovery HD. Select Reinstall OS X from the Utilities menu, and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible
because it is three times faster than wireless.
5. Reinstall Yosemite from Scratch:
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.

"Desktop & Screen Saver" settings not saving upon reboot.
"Desktop & Screen Saver" settings not saving upon reboot. Settings are always set back to factory default upon computer startup. Need help! Please!
Back up all data.
This procedure will unlock all your user files (not system files) and reset their ownership and access-control lists to the default. If you've set special values for those attributes on any of your files, they will be reverted. In that case, either stop here, or be prepared to recreate the settings if necessary. Do so only after verifying that those settings didn't cause the problem. If none of this is meaningful to you, you don't need to worry about it.
Step 1
If you have more than one user account, and the one in question is not an administrator account, then temporarily promote it to administrator status in the Users & Groups preference pane. You can demote it back to standard status when this step has been completed.
Triple-click the following line to select it. Copy the selected text to the Clipboard (command-C):
sudo chflags -R nouchg,nouappnd ~ $TMPDIR.. ; sudo chown -R $UID:20 ~ $_ ; chmod -R -N ~ $_ 2> /dev/null
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window (command-V). You'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning not to screw up. If you don’t have a login password, you’ll need to set one before you can run the command. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
The command will take a noticeable amount of time to run. Wait for a new line ending in a dollar sign (“$”) to appear, then quit Terminal.
Step 2
Boot into Recovery by holding down the key combination command-R at startup. Release the keys when you see a gray screen with a spinning dial.
When the OS X Utilities screen appears, select
Utilities ▹ Terminal
from the menu bar. A Terminal window will open.
In the Terminal window, type this:
resetpassword
That's one word, all lower case, with no spaces. Then press return. A Reset Password window will open. You’renot going to reset a password.
Select your boot volume ("Macintosh HD," unless you gave it a different name) if not already selected.
Select your username from the menu labeled Select the user account if not already selected.
Under Reset Home Directory Permissions and ACLs, click the Reset button.
Select
▹ Restart
from the menu bar. -

Display screen keeps resetting every 5 miutes
Our business computer is an Imac G5 10.4.11 Tiger. The display screen keeps resetting every three minutes. It just flashes and resets itself. I don't loose anything but it's very annoying. I've reset the pram & nvram with no luck. I've also done all the repairs off the start up disk. Any thoughts?
<Post Relocated by Moderator>Hey Michael,
I brought my Imac up to the Apple Store where we purchased it from. They had Friday & Saturday and called Sunday saying it was done. My wife brought it home and we plugged it in only to find it's still has the same problem. My wife said they went through the entire machine from top to bottom.
I called the store today and had to schedule my complaint with a service tech. I brought the machine up there myself and went through the steps (It kind of scares me when I know more than the kid helping me). I understand they have to learn somehow, I own a door & window company and totally see things from both sides. I asked for a supervisor, explaining I wasn't upset with the other staff person, I was just upset with the computer. I explained to them that I had removed the cover and looked at the capacitors with three of them bulging. I explained I had posted here for some answers and that I'd researched the issue. They told me all about the problems they had with this year and the capacitor issues were only covered for a three year period (I happened to be six months late) They then proceeded to tell me that it would cost me $900.00 to fix. I had to take a deep breath and keep my composure after that one.
My biggest complaint is they had problems with the machines logic board capacitors, but never told us it may become an issue. No letter or even the courtesy of telling us when it was serviced. I own a brand new 20" Imac, the 2005 Imac 20" (problem child), and around 10 other Imac's dating back to 2003, 4 Ipod Touch's, and 4 Iphones. Needless to say I have invested a large sum of money in Apple products. These are the only machines I've ever had since I can remember and I'll always support Apple products. It just really ****** me off when they had my machine in for power supply repairs a couple times and never said a thing to us about possible problems down the road. Now they want me to sack up $900.00 for repairs when I can get a new one for around $1200.00.
I know that these issues arise in every kind of industry. I deal with them all the time, but if I know there's a flaw that will kick my rear end down the road, I''l head it off as fast as I can to avoid angry customers. I also don't have the volume Apple has when it comes to sales, so my issues really have no validity, they have to cut it off somewhere. Is there any other route I can take to try and get this $2600.00 computer fixed without kicking my rear?
By the way, thanks for answering questions, I do it on a couple boards in my industry. I know how people beat you up on certain issues without knowing your doing it for free. I know where your coming from and want to say Thank You for your time!!! -
Sign into iCloud pop-up message on iPad2 won't disappear off screen, have reset password multiple times but it is saying incorrect. Please HELP unable to use iPad as message appears every few seconds, iPad was working fine until now.
After the restore did the phone work properly for a while? Say, a day or so?
If so it is possible you have an app that doesn't let go of memory properly. I reboot my iPhone ( hold sleep/wake and hole till you see the apple logo) every few days. This resets the memory. The iPhone OS has doesn't seem to mange memory very well yet. So a reboot will help with that. I have had my phone almost slow to a stop before I started rebooting. Always reboot after installing a new app. Also do you close all pages in Safari when you are done? This is a good practice. Safari will run in the background and use processor time and drain your battery quicker. Create a new blank page then close all others when you are done browsing for a while. I have also found that certain web site that have animated images like weather maps will turn the phone into molasses. As soon as i close that page it gets faster.
If all of the above have no effect then as Tamara said it is time for a trip to the Genius bar.
Good luck -
I have a the first generation flat panel (i've owned since they came out - an original switcher from pc) - 800mhz powerpc on 10.4.6. Suddenly my imac reset?!? My safari bookmarks are gone! My screen saver and background are back to a default! My itunes is like it's new...all 18.6 gig of music is toast...it's like i'm opening itunes for the first time!!!
I used finder to locate my music and found it, but is there a way to go back in time? what happen? what do i do now, what would anyone suggest...I want at the very least to get itunes rolling like it was doing an hour ago!!If you tried to change the name of your home folder by renaming it in the Finder, you didn't do it properly. Open the Users folder on your hard disk and locate both the folder with the house icon and the folder which contains your music and other data. Give the folder with the house icon another name, and then give the folder with your data the name the folder with the house icon used to have; when done, log out and back in.
To change the name of your home folder properly, you need to change the home property for your user account in the NetInfo Manager as well as renaming the folder in the Finder; don't delete or alter any other accounts, properties, or groups.

Flat Screen imac iMac won't boot up, will not boot from DVD
My 24" imac flat screen will not boot. I only get a blank gray/white screen. Reset the PRAM and tried to boot from the DVD. I held the C key down when I powered on but the system will not boot from the DVD. If I wait long enough, the DVD will eventually be ejected. I have had HD issues and Disk Warrior indicated that the drive was damaged. Will a dead hard drive cause the system to not boot from the DVD? Is there any way to get the system to boot from my DVD?
Hello PMcDer,
Welcome to Apple Discussions!
By what you are describing you're correct in believing your drive is probably gone. The sad news... if Disk utility can no longer see the drive, your ability to retrieve any data off of it is getting slim.
There are a couple of options for data retrieval.
1. If you still have Apple Care have them fix it. But make sure they know that you do not have a backup.
2. If you do not have Apple Care, have an Authorized Apple Tech replace the drive and make sure that they will give you back the old drive. This may prove to be a challenge. Or you can replace the drive yourself. It is not easy for some but take your time and you'll have no problems. Lots of youtube videos on this as well as on-line tutorials.
3. You could try a Hard Disk Utility program like Disk Warrior to see if it can help, but it's not free.
4. You could pay someone big bucks for Data recovery in order to get the data of the drive for you.
If you decided to do the HDD swap yourself. You could purchase a 3.5" firewire enclosure that you could put your old drive into once you do the swap. Plug it into the iMac and prey that it recognizes it. Then "MAYBE" you could copy the data over to the new drive, but that is a stretch. -

I have an ipad4. Wifi keeps cutting out after the upgrade even after I forget the network and resign on or reset all network settings. I deleted iCloud drive from my iPad, turned off Bluetooth, reset network settings, and rebooted my iPad. Since I upgraded to IOS8 this is the longest wifi has consistently been working for me. Which is approximately an hour now. Anyone else find that this worked or have figured out if this or anything out there is a permanent fix?
Hi CollinGCC78,
It sounds like you have been on the right track in troubleshooting this issue. If you are still having issues, you may want to double-check the steps outlined in the following article, in order if possible (apologies for replicating any steps you have already taken):

Blue Screen Crash Running Windows Update on Reboot
I installed Windows 7 and Boot Camp Support Software. Installation went smoothly and no problems. When I run Windows Update, it requires a system reboot; however, each time I boot into the Windows partition, I get the dreaded blue screen of death. Then on reboot, Windows runs startup repair and restores the last installation. I think the problem might be that I am installing too many updates at a single time but not sure if it's something to do with the Boot Camp partition. I deleted the Windows partition and reinstalled Boot Camp but the problem persists. Windows 7 works fine, but can't seem to install updates.
Did you get the Apple drivers installed off your OS X DVD?
Is that what you mean by "reinstalled Boot Camp" ?
Did you get Apple Software Update (in Windows of course) up to Boot Camp 3.2?
Try getting those installed before Windows updates more.
No need to 'delete' Windows partition, just do a custom clean format and install what you meant?
No need to deal with Boot Camp Assistant again, all that does is set aside and create a partition to begin with. -
