Screen brightness resets after every start up

Hi all, haven't been here in about a year. My imac's brightness has been resetting to the darkest point every time I shut down then subsequently start up (next day, whenever). I always had it set at it's highest point, which is what I preffered, and now I have to set it with the keyboard EVERYTIME! Not the end of the world but a little irritating. I don't know if it's related but also lately my normally smooth running imac has been hanging up on me with the spinning beach ball of death and I routinely have to initiate a "force quit" but don't have to actually force quit any app. for the imac to resume as normal. All I have to do is close the force quit window, wierd. 3rd party culprit?
Thanks guy's.

Sounds strange.. Have you done the usual maintenance people around here suggest... repair permission.. clean caches? That's what I would do considering your other problems.
May want to try a Utility like this:

Also, you may want to consider creating another account.. set that account to open upon boot... and see if the screen problem persists. If it doesn't, then it may be an issue with a preferences file...although I'm not sure screen brightness is controlled by a preferences file.. worth a shot though.

  • Blue Screen 15 seconds after every start up

    As it says, I get a blue screen (don't think its the screen of death) that only appears for a second or less once windows 7 has a chance to load. I think it says something about hardware, it could be telling me to check it. I can't get enough time to read it. AFter it appears the Mac just shuts down.
    I'm running a stock 2.8Ghz quad mac pro from last november. Just after the install it was fine, installed a driver for my wacom tablet and the windows support software that Apple suggested I download. I think it could be a funky driver. I saw somewhere online about a bad driver being supplied which caused something similar but that was from a few years ago.
    Any ideas?

    x: is the booted system, you have to change it to c: this is the system partition of boot camp
    at the command prompt type:
    c: [enter]
    cd [foldername] to change directory and cd.. to go back
    to move files type:
    move [filename] [foldername] if the level of the folder is the same as the file
    to move the file one level up type:
    move filename ../
    to rename the file type:
    rename [filename]
    when this is working for you and you are able to boot your system, you need a USB mouse since the touchpad is deactivated because of the missing drivers
    then download the newest Boot Camp drivers, after the install everything is working again.
    you can see the files when you are in OSX, but you can´t rename then, you need a NTFS Driver for OSX first, which allows you to write to NTFS Partition.
    Good luck!

  • Screen Brightness reduces after Mac OS Update

    I had updated my Mac OS to 10.6.3 from 10.6 on my macbook pro. I noticed after rebooting of my system, the screen brightness has reduced considerably. I reset the PRAM and noticed my brightness return back to normal lever but again reduced after login page appeared. Can someone provide me with a solution to the problem..

    Hi there,
    I experienced exactly the same when I updated one of my Macs recently. I was running the update & the screen reduced it's brightness as it usually does before it goes to sleep & then once it had restarted as part of the installation process, the brightness was more or less at it's minimum setting. I increased it to it's usual setting & this was then retained as usual. You shouldn't notice any further reductions in brightness as I believe this is just due to the screen's powersave process kicking in during the installation.

  • After iTunes Update (10.3) mouse and keyboard settings reset after every system reboot

    Since I updated to the iTunes version with cloud support (after Jobs' Keynote where the iCloud was introduced) my mouse and keyboard settings (see image) are being resetted on every system reboot.
    image: this is how I want my settings, but they're resetted to system standard when I reboot my MBP
    I don't know if there is a connection between the update and the resetted settings.
    Does anyone know a solution to fix this problem?
    Thanks
    Kris

    I solved it clearing PRAM and booting in safety mode as written in this article:

  • Dashboard resets to it's condition as of March 27th after every start-up

    As said in my subject heading, the dashboard on my Macbook resets to it's condition as of March 27 every time I restart or turn on the laptop. No matter what, every time I restart it, my widgets change and the information on my sticky notes on the dashboard are lost. Does anyone know how I can solve this issue?

    What condition was your computer in on March 27th? Does this issue appear if you open up a new account? Have you tried repairing permissions and restarting the computer afterwards?

  • After Mavericks, at start up, initial screen brightness too high and starting sound too loud, different than I left on previous shutdown. Didn't happen before the update.

    I've tried sudo nvram SystemAudioVolume=%80 for the sound, but it works just once... returns next startup's.

    The first thing to do is use smartctl to test the drive. Start with the short test ( smartctl -t short /dev/sdX ), and if it passes run the long test ( ... -t long ... ).

  • Brightness resets after restart

    recently the brightness has started to reset every time i restart. im not sure why... anyone have an explanation?

    There's a trick that some have reported to work. Go to System Preferences, change the screen resolution to something different, then back again. My guess is that this forces the PRAM settings to be saved, when for unknown reasons another change doesn't.

  • T510 screen brightness dims after startup

    I've noticed this on our company's new T510's we're getting.  When you start them up, the screens look to be full brightness.  But after a few seconds, the screen dims half way or so and you must manually Fn+[Home] to make it brighter.
    How do you change the default way this is set up so that it doesn't go dim after a few minutes?  Thanks.
    Solved!

    Hi and welcome to the forum!
    You can use lenovo Power Manger to create a new power scheme or modify the existing one to change such settings. Switch to Advanced mode to do so.
    Hope this helps.

  • Shortcut for action reset on every start of Photoshop CC

    Hey there,
    I have a problem I didn't have with Photoshop CS6 that now occured on CC since I just subscribed.
    I had set a shortcut for a custom action in Photoshop CS6 which was F2. Since I wanted to use F2 for another function (i.e. renaming layers) in Photoshop, I had changed the action shortcut to F4 successfully when working with CS6. However, on Photoshop CC, each time I start the program the shortcut is reset to F2. I already tried saving my shortcuts, but I assume that doesn't include the ones for actions? I can 'solve' it by manually copying stuff from the CS6 presets folder - which is far from ideal since I then cannot change it to something else in future either (will stick to F4 then).
    Anybody an idea what might cause this, or better: How to solve it?
    I am using the Windows version of PS CC, being on Windows 8.1.
    Thanks in advance
    enoversum

    Ugh, I didn't intend this to turn into a Mac vs. PC contest.  My only implication is this:  Mac users might be forgiven for expecting that their preferences are saved right now, vs. PC users who expect settings to be saved after a successful run and exit of something - because that's how most things work on each of those two systems.  Photoshop's philosophy is more PC-like in this case, even when run on a Mac.
    But that's neither here nor there for helping solve Eno's problem.
    Eno, if you add a new action set, does it still appear in the Actions panel after having closed and restarted Photoshop?  I'm still trying to gauge whether you're having a general failure to save preferences, or just some odd failure having to do with key assignments.
    The file your actions panel data is saved in on a Windows 8 system is here:
    C:\Users\YourUsername\AppData\Roaming\Adobe\Adobe Photoshop CC\Adobe Photoshop CC Settings\Actions Palette.psp
    Do you see its Modification Date getting updated upon exiting Photoshop?
    I'm wondering if somehow you have a permissions problem with that particular file.

  • Photo File Names Reset After Every Synch with iPhoto

    I have iPhone 3GS running iOS 4.0.1
    This only started happening in the last couple weeks: every time I synch-and-delete my photos with iPhoto (6.0.6), it resets the "file name" counter on the photos I take on the phone. I've been using this version of iPhoto and synch-and-delete as my photo saving method since I got the phone and before it would always remember the last photo number taken. Now I am ending up with dozens of photos in my library called "IMG_0001" etc, which is very frustrating when I want to move photos anywhere as a batch.
    Is this a new "feature" for iOS4? I can't find any settings that could be causing it on the phone.

    I noticed the same problem today when I tried to export my iphone pictures from iphoto into a folder with other iphone pictures from last week.
    I have an iphone 4 running 4.0.2

  • My clock is changing after every start of OSX Or WINXP. What is it?

    I had a problem in the beginning with my iMac: It didn't shut down correctly and made weird thinks. I brought is to the Apple Centre and they said that could be a hardware problem. After the inspection they said that every part is OK. Then I had to pay 80Euro because they made something with my software.
    They said that the timezone in some Appz isn't configured correct and that they did this for me. Now I have the same Problem again and it don't matters what i'm supposed to do with it, it doesn't stop.
    That problem began as i connected the mac the last time to the internet for update and turned on the automatical clockconfig over apple.
    I turned it off already but nor OSX nor Windows are remembering the correct time, even if i confiure it well and reboot after that.
    And after this problem the mac begins to do weird things like last time. The Appz aren't working correct and it boots and shuts down not correct and very long.
    If somebody knows something about that, please help me.

  • Settings are reset after every update...

    every time i update my ipod, all of the settings are reset (language, clicker, backlight, everything)... EVERY time...
    why does this happen???
    i've downloaded and am running the latest ipod and itunes software...
    please help!!!

    That shouldn't happen -- first thing I'd try is to restore the iPod back to factory conditions with the firmware updater (choose "restore") and then completely resync. Then make your setting changes and my hunch is they will "stick".

  • Wireless needs to be reset after every restart

    Hi all,
    I'm running 10.2.8, and use a Lucent waveLAN/ieee card with the Sourceforge drivers (WirelessDriverBeta5); they do a good job of connecting me to my wireless network. My one complaint is that every time I restart my Powerbook and want to go online I have to open the wirelessconfig utility in System Preferences and re-enter the setting (hex key, channel, etc.). Does anybody know if this is normal behavior for this card/driver set under Jaguar, or am I missing some silly little thing?

    Anybody out there familiar with the Sourceforge wireless card drivers? Maybe a link to a previous discussion I overlooked?
