I have a new iMac 2009 - 24' - 2,93Ghz, running the latest OS.
When I start, the brightness is at maximum... I set it to minimum, only to find it at maximum again when I re-boot the computer ! I tried setting it via settings as well... it just dosent stick !
On the flip-side, the volume retains its last settings.
the monitor's default brightness setting is far too bright for my eyes, so the first thing I did was to open the System Preferences pane and reduce the brightness setting. That worked fine until I shut the computer down. On rebooting, the brightness returned to its default highest setting. On my older iMac G5, the brightness setting always stayed put. It isn't a huge problem since adjusting the brightness setting does work, but I don't want to have to adjust it every time I reboot my computer.
I spent two hours yesterday on the phone with Apple support trying to fix the problem, even going so far as to reinstall the system software with no success. The woman on the phone finally suggested that I return the Mac for a replacement.
Has anyone else here with a 2009 iMac experienced this problem? Is it possible that it's hardware related? If so, could this be the tip of the iceberg suggesting a potentially larger problem down the road? I would have guessed it might be a software glitch. (The new iMac has thrust me, finally, into Leopard; until last week I was using Tiger on my older G5.) I bought the 3-year Apple Care with it--since the new iMacs have only been out a week, should I wait until the next Leopard update and see if that fixes the problem?
All of a sudden, every time I reboot, my screen's brightness is all the way up. So, I go to 'Preferences' and bring it down to only happen again the next time I reboot. Not a terrible problem, I hope, but not sure why the settings of this doesn't remain as I left it last. Perhaps I have picked up something OR I have a fault which could get worse?Anyone seen anything like this?
View 3 Replies View RelatedMy wife has an iMac (I don't know any other way to identify it e.g. model number), and she has this 3rd party calibration software that I'm trying to use. I am not used to a Mac, and I cannot find the display settings for the monitor. There are no buttons on the monitor, and when I go to preferences, I can only find the brightness control. I've googled this and cannot find a clear, simple answer. I have used every version of Windows (currently on 8.1 on my PC) and it's easy for me on that platform. I suppose it's just that I don't really know how to navigate Mac OS.

I am calibrating my system with spyder2 and it wants me to set my brightness back to the default. What is the default setting for the brightness?

My problem is this: within the last month the brightness setting has shifted from bright to dull all by its self.

I use my MacBook pro on battery most of the time and every time I go to turn up the keyboard brightness its in a different place. I want to set it to be at a specific brightness when its plugged in and when its running on battery, at a lower brightness but the same every time. I want to be able to have settings for the led brightness.
View 1 Replies View RelatedHere's something I've wondered on and off for a while, just remembered it now so I'll ask.
The enduring issue I've had with all of Crudbooks (well, among many other issues - but they've usually been different for all models/refreshes of Crudbooks) is the screen brightness on AC and battery. It doesn't seem to intelligently switch in the way that for example Windows does. Or to put it more specifically, it doesn't seem to remember brightness settings for AC and battery modes that well.
It is of course the matter of a few seconds to adjust the brightness but I wonder if there's a way of doing it automatically. A potentially basic question, but something I've never bothered to find the answer to. Any takers?
What setting do you use on your new MacBook Air? I'm currently at an older non-LED MacBook, and when working with the LED-screens on the newer MBPs I kept noticing that I couldn't really find a proper backlight settings. The top 3 where OK but everything was almost too bright, while lower settings made everything look very dark and greyish.
I played around with the Airs a bit in the store, and I think they were very similar in that regard. But it's hard to say because of the store lighting and not being able to use it in various situations with different lighting.
I need to change the color and brightness for a video file for a presentation and cannot figure out how to change them permanently when I open the video file in Powerpoint. When I open a video which I have altered the AV settings on in another program, the settings revert to the initial settings. Can I edit the color and brightness settings permanently in Quicktime 7?
View 1 Replies View RelatedUnder normal office lighting, I find anything other than 100% brightness seems too dark. But I've been getting huge amounts of eye strain so am wondering whether to turn in down some more, say to 50-75%, but worried that will strain my eyes even more. What do you guys have your 13" set to, assuming good ambient lighting?
View 10 Replies View RelatedI went to Best Buy yesterday and they just got the new imacs in and had on display side by side. The 21.5 display was not as bright and vibrant as the 27 display. The apple and best buy guys could not tell me why the difference. The settings were checked and found to be the same for both machines. I was going to get the 21.5 but now not so sure. I definitely like the brighter 27 better. Is this normal? Why is the 27 brighter? Has anyone else noticed the difference?

i bought this iMac in May 2011. I believe this model doesn't support Memory stick pro.

iMac (21.5-inch Mid 2011)
The brightness goes up when you plug in your MBA, but then over time it just goes up and up. I honestly like my brightness pretty low (rarely more than half, typically at 3-5 notches), but it just keeps on going up and up. I almost never set it above half, but multiple times a day, I notice that it looks pretty high and it's at like 3/4 so I put it it down to about 1/3, but after a while, it's just up again.
Anyone else notice this? What is it, why does it do this? How can I fix it? I don't mind not having auto-brightness (even though I loved it), as long as my screen doesn't keep going up.
Or does it really matter will any brand do or would you recommend a specific brand for an iMac?
View 2 Replies View RelatedI wanted to bump up the ram but was wondering if I would have any problems by just adding 1 extra stick of 4 gb for a total of 8gb(qty.2 2gb+qty1. 4 gb)
I've got a 128 gb usb 3.0 stick from "platinet". I could normally use it for some time but didn't need it during the last months. It was carefully transported now and then but mostly packed away, so it's possible but unlikely that it's damaged.
Yesterday I wanted to use it again and it got recognized on my iMac (OS X, 10.9.4, iMac mid 2007) for only some seconds, then the message appeared that it was not removed correctly. After that, the usb stick wasn't detected anymore on neither my iMac nor two MacBook Airs (also 10.9.4) that we've tried. I haven't tested it on a Windows computer yet.
Disk utility doesn't detect the device either but it can be found with "about my Mac" --> "system report" --> "USB"
I do not care so much about the data stored on it but I would like to get it to work again and not to throw it away.... Is there anything I can do?
I have a 27 iMac, and a 22 inch Viewsonic as the second monitor.
The second monitor is just not bright. I have used another monitor as a second monitor as well. Both are just not bright enough to suit me.
I have fiddled with the brightness controls, to no avail.
Is that a generic problem with second monitors?
They just don't get enough juice or something?
Would another brand monitor help?
Can I clone my hard drive in my iMac and stick it in my Mac mini and expect everything to work smoothly? Or are there specific drivers installed on the iMac drive?
View 2 Replies View RelatedMy relatively new iMac 27" accepts and reads the memory stick on my Canon EOS Sxi, and my Sony dsc-h55 Cybershot. However, my wife has an earlier model Sony Cybershot, with a SanDisk Memory Stick Pro Duo, and the iMac doesn't read it. I put it in, and nothing happens. With the other mem sticks, after I insert it into the SD Card slot, iPhoto starts, and reads the contents of the card. Should it read the SanDisk Stick?

i got a question about adjusting the brightness level on iMac.
i adjust the brightness to lowest but each time i restart or turn the computer back on, the brightness level would set back to highest. Is that for all the imac? is there a way to set it?
Am I the only one having this bug? I have a 2009 24" iMac Radeon 4850 and after installing the 10.5.8 combo every time the machine boots the brightness is set to maximum.
I tried zapping the PRAM and that didn't help.
The other problem I noticed is that my startup network shares, even though checked to "hide" pop up finder windows at boot time. It never did this before (even without hide being checked).
Computer has 2x512 memory sticks. Can I add one 2gb stick since the CPU sees only 3.3gb total? I realize I'm losing dual channel capabilities.
View 1 Replies View RelatedI bought my aluminum imac when it was released in late 2007. I had a 1 gigabyte stick up until now, but I decided to upgrade to 2x2 gigabyte sticks. When I took out the 1 stick and placed the new ones in, my computer would sound like it turned on, but the system really did not boot up. I have tried many configurations to see what the problem with the RAM is, and all I could figure out is that the computer will only boot up if the original 1 gig stick is in one slot. I checked both sticks with this, and they seem to register on my mac when I check the "About This Mac" section. Basically, I get a black screen if I use only a 2 gig stick, or both 2 gig sticks. I can have a maximum of 3 gigs so far, but I really would like all 4 that I paid for. I'm not so sure that it's a problem with the ram, especially because it is recognized by the system, but it can't boot up the system, so I am simply dumbfounded. Anyone have an idea what the problem is? I just recently installed Snow Leopard prior to getting the RAM if that has any importance.
