OS X :: Increase Brightness App?
Jun 24, 2010
My Apple ADC Studio Display has decided to stop all of it USB ports from working and as anyone who knows about these monitors you need to connect the monitor to a USB port to get the Brightness control to work, are there any apps out there which can control the brightness of the monitor up or down. I have played around with Calibration but I still cannot change the brightness of the screen. I have searched around for some solutions but all I have found is brightness controls which turn down the brightness but do not allow you to adjust the brightness up

Just got the new MacBook Pro Retina, and I love it except for the fact that the overall brightness was decreased by 20-25%. A couple reviews talk about this noticeable reduction in brightness [URL], and I assume it has to do with the power consumption of the retina display.That said, I've always thought the highest brightness in previous generation MacBooks was barely bright enough as it was, and now with this reduction in default brightness, I'm finding it hard to use. I know I may be in the minority thinking this, but I may have to return the machine if I can't find a workaround. Is it possible to increase brightness beyond the default setting? Is there a command line setting that I can adjust? I'm well-aware of the battery trade-off this will have, but I don't care. I have to be able to see the screen.
Info:
MacBook Pro (Retina, Mid 2012), Mac OS X (10.7.4)

I have a 15 inch aluminum macbook pro, Snow Leopard and recent updates all installed, but i noticed something on my friends 13 inch macbook pro that mine doesn't do.
On my friends, when you press the screen dim/bright button (F1, F2), its a gradual transistion, but on mine it just jumps down a notch.
For example, when you hold down the dim button on my friends MBP, it the screen dims in a similar way as to when you put your finger over the iSight camera, it fades to a dimmer screen.

I've noticed recently that my screen brightness will suddenly increase or decrease by itself. When I press one of the control buttons it indicates that it is 3 or 4 steps higher or lower (obviously allowing for the fact that pressing a control button moves you one step anyway!) I have the 1.8 SDD. I love the machine....but anyone have any ideas about this. It only happens under battery power.

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.

I 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?

I 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?

for my macbook pro, it has a button that will kill the keyboard light, then restore it when pressed again, i need a button, or an app with a hot key, that does the same thing for the LCD backlight, i often leave the machine on and that requires the lid being open, so i have to hold down the dim button until it goes out, then restore it the same way, so thats what im looking for any ideas?

Seeing as I have lost my brightness slider in Prefs/Displays and my F1 F2 Keys do not function as the brightness control
can anybody suggest a brightness App I can use ?
Well other than Shades or Brightness because both of those mess with your colour profile/profiles.

I have heard that it is possible to increase a mac's or any computers ram by adding a high capacity USB memory drive to a open port. With special software the OS would write large infrequently used files to the stick and keep the most frequently used ones in the systems on board ram for greater speed.

This probably seem like a pretty n00bish question but I'm considering getting some SD ram for my macbook and I'm wondering if it makes a difference what kind you get?
I've had a look around and i'm unsure if it matters what format your computer is? As in can I take a ram chip from a pc and put it in my macbook?

My Macbook Air is doing something pretty strange..
This is as far as my brightness will go up. This is using the keyboard brightness thing on F1 and F2. When I go into the system preferences, I can drag the brightness to the top, but as soon as I release the mouse, it automatically flicks back to where it was before without getting any brighter.
Does anyone have any ideas as to the cause?
The model number of my macbook is A1342 if that helps.

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?

I recently bought a new Kensington Slimtype keyboard for my PowerMac G4 (dual 867mhz); it's running Leopard and everything other than this is working beautifully. For some reason, whenever it goes to sleep, it turns the brightness down to it's lowest setting - not a huge problem, I just turn it back up. Just wondering if anyone else is having this problem and if they are, how did they rectify it?

I have a Macbook Pro 13.3 ", only a few months old. When I use this, whether I use the word, web surfing etc then adjust the brightness of the screen itself from strong to weak and back, all the time. This happens both when connected power and do not. And no, it's not that it goes into power saving mode, this occurs during use.

The brightness is turned all the way off on my MacBook pro and the only way to turn it back up is through system preferences. But I cant see it and everytime I push the brightness control keys it makes a beeping noise. And won't do work.

I have a 2012 macbook pro and needed to change the brightness of my monitor for my eyes, the problem is I find it hard to see the tab bar now because it is too dark. I looked on these forums and found how to change the brightness of the tab bar without compromising any of the other parts of the screen, but it is not for my particular year or model " [URL]

I have a PowerPC G4 466 Mhz which has three "PC133" thingies in it, one 128 MB and two 256 MB, totalling 640 MB.
I want to change those to one, two or three 512 MB cards instead, but the manual says something about there being certain restrictions for 512 cards. Translated from Swedish:"If you install DIMM-modules of 512 MB they must have 256 Mb-units". What does that mean exactly and how do I check that they in fact have "256 Mb-units"?

I have a 2007 MacBook Pro 2.33GHz Intel Core 2 Duo with 2 GB of Ram (1x1) and recently upgraded the operating system to 10.5.8.
The problem is that the computer has slowed down considerably especially since I also installed CS5.
I'm thinkin that it is a ram problem and need to upgrade but through my research it states that my computer won't take anymore ram which is unbelievable. Can I install more ram or do something else to make it faster?

When I turn my brightness all the way down, there's still a barely (but clear, still) lit circle at the centre of my screen. I have a 13'' mbp. I can even see my cursor and move it around. This spot, at very low screen brightness, appears kind of yellowish. When I turn the brightness up, it is not noticeable. The circle part has roughly a two inch diameter.
I've had the mbp for about a month, and just noticed this now. I do turn my brightness down quite a bit, but its usually in a well lit classroom and thus its possible I just did not notice this circle that is still barely lit until now.
UPDATE*: I have just discovered that covering the lit apple logo on the screen's exterior (directly opposite the lit circle i suppose) causing the circle to gradually disappear. THe laptop is sitting behind a window (ie light can shine on that apple logo)...what's up with this?
