Just had apple replacing the display on my rev b air due lose hinges, I think this new display much brighter then the old display. It is just a psychological thing? or does the screen actually losses brightness over time/usgae?

I found the setting under Displays to automatically adjust brightness, but is there a way to set this different for Battery or Power Adapter? I would like to keep this option on for using the Battery, but would like the display at a constant level when using the Power Adapter.
View 3 Replies View RelatedRecently, after about 5 minutes of use (not sitting idle), my MacBook's screen will go very dim. I hit the buttons on the keyboard to take the brightness all the way up, but it doesn't get much brighter and there's only one thing that I can do to make the screen go brighter: I go into System Preferences and click Display. The second I click that, the brightness returns without me doing anything in the Display section, so after Display comes up, I just close it out and the screen brightness is fine for a while. It seems to do this after the lid has been closed for a while and then starts dimming again after opening the lid and using it for about 5 minutes. Is there a way to fix the auto-dim mode without disabling it? MacBook (white) is running Leopard 10.5.8 with all the latest updates.

View 1 Replies View RelatedBasically what I want to do is sync my Apple Cinema Display's brightness with my MacBook ambient light brightness control. So when the brightness of my MacBook changes because of ambient lighting, my secondary monitor changes with it. Is this possible? Is there a software that does this?

View 2 Replies View RelatedThe reason I am asking is that I am using a Spyder colorimeter to calibrate my monitor and it is asking me which controls exist on the display:
-brightness
-contrast
-backlight
My thinking is that F1 and F2 control the backlight level and not the "brightness" level, if you get what I mean.
Since I have purchased my MBP the screen changes in brightness from time to time. Its been about a little over 7 weeks of ownership and I have noticed it for awhile but now it bothers me a little. I use my MBP 15 i7 4gb ram HD AG in class/school majority of the time. In class I use my MBP at about 1/2 brightness (compared to full) in this fixed setting I have had the brightness flicker between bright to slightly dull and back. I have not dropped my MBP nor any other sort of damage so that's out of the question.

View 1 Replies View RelatedI don't know much about RAM and how it really works but here's my question: (i have new unibody 13" MBP w/ 4GB RAM) When i do a fresh restart i have anywhere up to 2.5-3GB free with basically NO applications open. But as time passes, web browsing, sleep, etc the amount of free RAM available goes down to <2GB even when i exit all apps...
1. Is this typical? What's the explanation for RAM being eaten up over time? Is it advisable to do a fresh restart every couple days or so just to free up RAM again?
2. Is it even common with 4GB of RAM for half (2GB) of it to be used all the time? (I'm guessing yes, but just wondering what's the explanation) For those who only have 2GB of RAM, do they always have 1GB being used? Or would even those 2GB's always be taken up?
I recently purchased a unibody macbook pro 2.8Ghz (awesome machine by the way) and was wondering whether would the LED screen get dimmer over time like the previous non unibody models?
When I had my powerbook and non unibody macbook pro, I had a habit of keeping the brightness at full and realize after a while it starts to get dimmer and dimmer. A good fren alerted me to try and keep the brightness at 50% to conserve battery life was wondering do u any of u notice the same dimming occuring on ur UMBP?
Every time I close my MBP screen I have to re-enter my WEP password for my wireless network. This is very frustrating and I'm not sure if it is just an issue with keychain or if it is something else. If it is keychain I have no idea how to fix it as I have tried everything I know.
View 2 Replies View RelatedThe 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.
I have setup the 23i cinema display with mac pro. I have connected the USB and firewire cable to mac pro.. and keyboard is attached to back of the display. For some reason I cannot seem to adjust the brightness of the display from the keyboard (though I can do it from the side of the monitor). Neither can I see the brightness slider bar in the display settings. Also while the display is the the power led in the front blinks 3 times, then there is a little pause, and blinks 3 times again. How to fix this brightness control issue with the display. I have reseted PRAM and NVRAM... still nothing has changed. Also note I do not have and options tab for some reason.... (I have tried to plug the display's usb into the back 3 usb of the Macpro... still nothing)
View 1 Replies View RelatedI have a 24" LED Cinema Display and can no longer control the brightness settings in OSX I believe when I applied the recent java/bluetooth updates the slider disappeared upon reboot. I did some searching and can't come up with a way to get it back. I'm using a 15" Unibody MBP, and the brightness slider for that screen is available and does work. I also tried setting the keyboard shortcuts on my main keyboard (external) to turn up/down the brightness but they won't function at all.
I have tried zapping the PRAM, repairing permissions, and disconnecting/reconnecting the display, as well as booting with no external display and nothing has made the slider reappear. I also logged-in as a different user and the slider is not there for the Cinema on that profile either. I really, really hope I don't have to reinstall OSX to get rid of this but I'm out of ideas. The worst of it is that I turned down the brightness to less than half (when it worked) becuase I had a headache and now it's stuck there!
I have just realised that the Brightness slider in Display Prefs on my Mac Pro is missing. Running SL 10.6.2 with an Apple 24inch ACD connected.

Having just bought the OWC 60GB SSD I wonder if the 50USD Maxconnect 2.5" adapter is worth the money.
My other (and cheaper) option is the Icy Dock adapter 3.5" case, I only wonder if the additional connectors etc in the Icy doc cause any speed losses on the SSD?
As sexy as the Maxconnect is ... looks aside, is the Icy Dock any good in terms of speed or does it actualy slow down the SSD.
I have a 24inch LCD ACD display connected to my Mac Pro. This display all used to work OK, but now, read on. I had to send this 24inch LCD ACD display away to have the panel replaced. Since it has returned when I look in About This Mac/Displays it shows that I have an iMac connected as the display and now the brightness cannot be controlled. If the 24inch LED ACD is connected to my Macbook it all works as it should
My 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'm a longtime IT guy but a Mac n00b. My wife just got a 13" MBP and we really like it. I have an external drive that I've been using for Time Machine. When I did the initial time machine setup several weeks ago it said that the computer had around 100GB to back up (lots of photos). It took a while but finally completed. No problems. I looked at the external drive and the amount of disk being used jibed with what I knew it should be using. Fast forward to yesterday. I happened to look at the external drive and instead of 100+GB being used, there was only 14GB on the disk being used. Whoa. I *HAD* stopped a time machine backup earlier in the day because we were doing some things and I didn't want any other processes going on. Could stopping a TM backup (from the TM menu bar menu) cause something like this? I would certainly hope not. It should not have been deleting files at all--we are FAR from using up the entire disk.
I manually started a TM backup last night and it backed up ~ 100GB (I watched it's progress in the menu) and all was well. After it completed I went to the drive via the Finder and verified that disk usage was what I should expect. I just cannot figure out how it went from around 100GB used down to 14GB used and then back up to around 100GB. Frankly, it concerns me quite a bit. Does this make any sense to anyone out there?
On one of my Macs I've still Snow Leopard running and I'm using Time Machine for backups.
Question: After upgrading to Lion on that Mac, will I be able to continue "incremental" Time Machine backups OR will I have to make a complete Time Machine backup of the entire hard drive?

View 2 Replies View RelatedI have dual ACD's. How do I make it so that both screens have the same brightness? If I adjust the brightness in the display settings it adjusts the main screen, but then not the other one. How do I make them the same?
None of the issues discussed in the apple support page on this issue seem to apply to me (except one below regarding not completing the 'prepare for backup'). It still takes way too much time (a night is not enough) to prepare for time machine backup, even though there was a backup recently, and it is not a one-time event but a recurring problem, and there are no big changes to my files or disks.And of course because most days it does not complete the backup before I have to leave to work, the condition on 'not interrupting the backup' cannot be respected. This looks like plain poor design.The only thing that helps is to connect my laptop directly to the Time Machine by Ethernet but it is very inconvenient.

I will be purchasing the new Core i5 15" MBP in a few weeks and have been reading a lot of good things about it. With all the good things I see a few bad. I was wondering if anyone with the new MBP could answer these questions?
1. Is the Display better than the last generations? ( In particular the high res)
2. Someone said in another post boot time is slower than the 2009 C2D MBP? Can a few people confirm this?
I have read a few people say the new screens are less brighter than previous models and this has me very concerned? Of course I hope they actually turned up the brightness setting before making such claims.
