OS X :: Terminal Command To Disable Ambient Light Sensor?

Sep 16, 2010

My end goal is to create a script that will disable and enable the Ambient Light sensor when I plug and unplug my MacBook Pro from power.

To do this I'm pretty sure I need a terminal command to enable and disable automatic dimming as the ambient light changes.

MacBook Pro :: Disable Ambient Light Sensor (auto-dimming)?

Apr 28, 2007

I've noticed that the ambient light sensor in the MBP can be somewhat sensitive. Sometimes an action as simple as moving my hands up to the keyboard (from the side) triggers the "auto-dimming" feature of the screen and it slightly reduces the brightness of the screen, then quickly returns. This is rather bothersome.

I've got the option under Keyboard and Mouse "Illuminate keyboard under low-light conditions" unchecked, but the screen still dims if you cover the speakers. I've also got the option under Energy Saver "Automatically reduce the brightness of the display before sleep" unchecked as well.

I'm at a loss here. Is there not a way to disable this auto-dim feature? A Google search didn't turn up much of anything. Surely there must be a way...

PowerPC :: G5 - What Does The Ambient Light Sensor Do

Dec 6, 2008

[URL] I went here. I have found out the iMac is a 2nd gen iMac G5. It has an ambient light sensor. I put my hand over it and it doesn't appear to actually do anything.

What is it supposed to do?

Do new ones have it? I have a 20" aluminum one as well, but don't see a sensor.

MacBook Pro :: Ambient Light Sensor Is Too Sensitive?

May 12, 2010

I've been using my mum's MPB C2D quite a bit, in anticipation of my own i5 arriving, and one thing that gets on my nerves is the ambient light sensor. It seems to be really sensitive, to the point where it will change the screen brightness when there has been no real changes in ambient light. If you move your hand over the sensor at the top of the screen, or even if someone walks past and casts a shadow it can change for a few seconds. Also, just moving the laptop around and the sensor changes the screen.

Obviously this setting can be turned off, but I'd like the feature if it wasn't so sensitive. Other than that, I love the MBP and can't wait for mine!

MacBook Pro :: Ambient Light Sensor Not Working?

May 16, 2010

As of today, I noticed my ambient light sensor doesnt seem to work. I tried disabling and re-enabling it in system preferences, but that hasn't done the trick.

Is there some test I can do to see if it's working or not? I know it worked two days ago, because i took the i7 15" MBP outside and it automatically switched to max brightness. Today I took it outside and the brightness didn't switch at all and I couldn't see the screen it was so dark.

Since the last time it definitely worked, all I've done is install Windows 7 64-bit with Boot Camp and hooked up the MBP to an external 20" monitor with a minidisplay-DVI adapter.

Way To Show Just Ambient Temperature Sensor Reading On An IMac?

May 12, 2012

Is there a very simple way to show just the ambient temperature sensor reading on an iMac? Not for geeky or engineering purposes. Just to know the temp that the machine and the human are in.iStat widget shows it but really tiny, buried in all the other data,and only if you launch Widgets.Ideally, it would just work in the background and the temperature would show up in the menu on the right side. Maybe next to the time. Alternatively, as a little floating window on the desktop.Yep, just want to see the room temperature using the iMac thermometer.

Info:
iMac, Mac OS X (10.6.8)

PowerPC :: Ambient Light G5 2.0 Imac Shut Off?

Oct 28, 2009

So I've done all I can find on the internet on helping my broken computer. It used to have the noisy fan issue and then it would shut off. Now after being off for 12 hours, it may shut off in 2 minutes, maybe in 30. I have reset the SMU by unplugging for 10 seconds and then plugging in while simultaneously holding the power button, then turning it on. Ive also reset the PRAM, but it still seems to shut off. Is it a bad power supply? I dont ever hear the fans blowing hard anymore.

If anyone has basic things to do, I'm all ears. I know last step is probably just reinstall OSX.

I'm on 10.4 right now.

OS X :: MacBook Air Ambient Light Kernel Panic

Mar 19, 2010

A MacBook air that I just got up and running again after replacing the hinges along with the whole top half of the computer. I did a clean install of snow leopard, and was so happy to be using the air again.

After changing some settings and loading a couple off apps in my room with the lights off (so I could see the backlit keyboard), I flipped on the light switch in my room, and was immediatly shown the the kernel panic screen, and was forced to shut down.

I figured this was just a random occurance, so I booted back up, but was in kernel panic as soon as snow leopard booted. Went through this a couple more times, then shut the lights in my room back off, rebooted, and was able to boot up just fine. I then took a flashlight and ran the beam across the ambient light sensor, next to the camera, and was instantly in kernel panic again.

After saying WTF for a while I decided to swap the camera/ALS/mic board over from my old screen bc I figured maybe this new one is just bad. But this resulted in more of the same. I then did a new fresh and clean snowleopard install, but about 5 mins after finishing the install, it went right back to the good old kernel panic screen.

Now I don't really know where to go from here. The computer is way out of warranty, and after what I was quoted from my local apple repair store to repair the hinges and screen that I just fixed, I think I would just get nauseous at the thought of having to bring it to them now.

MacBook Pro :: Disable Sudden Motion Sensor After Upgrading To SSD?

Aug 25, 2014

I put a 1TB Samsung 840 EVO in my MacBook Pro (9,1).  Should I disable the sudden motion sensor?  Does it do anything else other than park the hard disk (like something with the fans)?

MacBook :: Motion Sensor Kills Back Light?

Mar 29, 2010

Here's a new one (for me anyway).

2007 MacBook: 2.16 Ghz, 3GB RAM, Intel GMA etc.

Anyway, all of sudden, any motion I make kills the backlight of the screen. In the right light you can still see things and the computer still works perfectly, just extremely hard to see. Have to do a restart in order to get going again.

MacBook Pro :: Light Sensor Turns Up Brightness Of The Backlit Keyboard

Apr 29, 2010

So I've recently purchased the new 13" MBP, and to my understanding, there is a light sensor that turns up the brightness of the backlit keyboard and screen when in dark environments.

However, the problem with my MBP is that when I turn on the lights in my room, the screen brightness and backlit keyboard both turn brighter, and when I turn off the lights, the screen and keyboard grow dimmer, which is exactly the opposite of what is supposed to happen.

OS X :: Command To Clear Terminal?

Oct 5, 2010

Is there a command to clear the terminal screen that works like 'cls' on Windows? I know about 'clear', but clear just moves the prompt on the top of the screen, leaving the previous output visible if I scroll up.

A friend suggested 'clear_console' (I think he's on debian) but I can't find it on OS X or MacPorts.

I want to run some terminal commands fairly often... yet I don't want to have to type them. I just switched from windows, so I need some help as to how to do this.

In windows I would've just used a batch file to run command prompt commands. I need something that will let me just run it and it will automatically run the commands.

I can use the Control>C command to quit that and return to normal. But it's a waste of time and I can't seem to figure it out. A Genius Bar Genius said to Archive and Install, but I don't think it's necessary. I just want to know how I can find whatever it is that's screwing it up.

OS X :: Cannot Run Sudo Command In Terminal

Nov 29, 2009

I can't seem to run a sudo command in the OS X terminal. Every time I run a sudo command, I get no response, as if the command is not run at all. My sudo appears to be broken somehow. I've got a problem with mounting an NTFS drive that is dirty. I have a command I am trying to run using the "sudo" command, but it is not working.

Code: sudo /usr/local/bin/ntfs-3g /dev/disk0s3 /Volumes/WIN XP -o force

After the sudo, I am prompted for my password, but after that the only response I get is another prompt, as if the command was totally ignored. I have tried many different commands after the sudo, and cannot get a response from anything. I even tried "sudo tcsh", which should open up a new shell, but nothing. "sudo ls" also shows nothing, just another prompt.

OS X :: How To Run A Terminal Command When Logging In

Jul 23, 2010

What is the best way to run a terminal command when logging in? And by �best� I mean �fastest.� I�ve been encapsulating my commands in an Applescript, but it�s terribly slow to load, and I�m hoping there�s some UNIX back-end I can use to speed things up.

Specifically, I want to run a shell script that I wrote. It decrypts some folders inside my Home directory so I can use them (this part works seamlessly, I just need it to auto-run itself).

OS X :: Command For Opening Files In Terminal?

Jun 25, 2006

You'd think this was all pretty basic. It probably is.

I'm trying to open/edit '/usr/local/php5/lib/php.ini' with TextWrangler through Terminal. The TextWrangler part isn't an absolute requirement. The directory exists and I'm assuming the file does as well. (No 404-esq errors during my fumblings and it was a standard installation of PHP5)

Also, is there any way to browse through the above directory using the Finder's GUI? That would be nice.

MacBook Pro :: Can I Screw Up My Mbp With This Terminal Command

May 28, 2010

Just bought a new MacBook Pro yesterday and I'm having trouble getting Time Machine to work with my NAS (WD My Book World Edition which supposedly supports Time Machine after their last firmware update). Time Machine sees it and starts writing to it but then stops recognizing the external NAS drive even though it's still connected to the network and I can access it and its files through the Finder.

So I did some Googling and came across this article and this command line...
