Adjustment brush not working on Power Mac w/ Snow Leopard

Running Lightroom 2.5. I've done permissions repairs, run DIsk Warrior and a re-installed - nothing works. Works fine on my laptop with Tiger. Power Mac 2.66 Ghz Quad, 6 Gigs of Apple Ram, OS - 10.6.2. The brush is visible, lays down a point, but makes no visible change to the image. I'm totally frustrated with this.
Anybody else having this problem? Any ideas?
Thanks,
Rich Quindry

Sorry,
My post above should have read Mac Pro. I recently switched and keep getting the names mixed up. Doesn't help that they look the same.

Adjustment brush not working on new Mac with Snow Leopard

Just purchased a new computer a couple of weeks ago. Not sure if something is incompatible or something else. I'm can't remember if the brush ever worked on the new machine. Also updated to Snow leopard 16.2 during this period.
I see the adjustment brush and can change it's size and feathering, flow and density are set at 100%, masking is off, it set down control points, but that's it. It makes no visible changes to the image in any mode. If I put exposure at 4 stops and place it on a mid-tone there is no change to the image, either in Lightroom or upon export.
I've run permissions checks, trashed the preferences and repaired the drive with Diskwarrior all to no avail.

Should I try a fresh install of Lightroom??

Lightroom adjustment brush not working

My adjustment brush was working fine, I took a break, and when I came back the brush won't do anything. The pin appears but the image doesn't change. I've tried adjusting size, feather, and flow all over the scale, and I've pushed the exposure down as far as it will go so I can see if anything happens. None of the regular exposure, highlight, shadow... settings are doing anything. It is showing up in the history bar but no change to the image.
I have tried closing and reopening the program and restarting the computer. It's been several days and I still can't get it to work

Safari Download not working on Power Mac G5

I am running 10.3.9 system software with 512MB ram. It is the model with all the hardware in the monitor (19" I think) , it has no tower.
I cannot install the new snow leopard system software or updates to several software programs including safari.
My questions are, is it time to just buy a new Mac Book for 999.00 or are there cheaper upgrades that can be done (More Ram) and keep the existing model.
I currently have the new macbook pro and love it, but the other MAC is for family use?

Hi Dave,
Time to buy a new Mac for family use. You can't upgrade on the old model to Snow Leopard because it requires an Intel Mac.

Isight is not working anymore after updating to snow leopard

it used to work very well. i updated snow leopard 5 days ago. i try to use skype and photo booth, it is never working again. do people have the same problem?
thank you for your information

Thanks for the info - however surely this has something to do with the snow leopard software update - not a hardware failure or is that just a coincidence?
My iSight was working fine before I upgraded to snow leopard? Is there a software fix coming?
Welcome to Discussions, lightwright
... this has something to do with the snow leopard software update ...
You may be correct that the problem has something to do with your SL update, but, as previously explained, many of us successfully use iSight every day after upgrading to Snow Leopard, so the problem is not SL itself. If you believe that your problem is with your update, you should consider reapplying the update using the method suggested above.
If you continue to have iSight problems after properly applying the SL update, consider all relevant troubleshooting suggestions in http://support.apple.com/kb/HT2090
However, if your iSight problem continues, and if iSight now does NOT show as a USB device in your Mac's System Profiler, yours is most likely a hardware problem. In that case, contact Apple or an Apple-Authorized Service Provider for service.
If, after properly applying the SL update and using the Troubleshooting suggestions, iSight IS recognized in System Profiler but still does NOT work with any of your video-enabled Apple software, your disk may contain some pre-SL software that is causing problems. Either erase the disk and apply only Apple software to see if that fixes your problem, or seek help from your Apple-Authorized Service Provider.

Lightroom 5.5 for Mac Adjustment Brush not working

Hi all, since updating to Lightroom 5.5 for Mac Adjustment Brush has stopped working entirely. I can open the menu and it does display the brush within the menu. When dragging the tool into the image it changes to the mouse arrow which doesn't have any function. Any ideas? Thank you very much for your help. Chris

And- do you actually press or hold down the left-mouse button and drag the cursor on the image? as you would a paint brush. A 'Pin' will appear where you start the brush stroke.
And- Is it possible that you have the switch at the base of the brush panel sliders turned off ? (The toggle switch on the same line as "Reset" and "Close")
Pressing "O" only turns the overlay mask on/off to give a visual indication 'Where' you have applied the brush.
Pressing "SHIFT+O" changes the colour of the MASK overlay- Red, Green, Grey, Clear
"O" does not affect any editing of the image.

Adjustment brush not working in camera raw cs6

The adjustment brush in Camera Raw PS6 is not working properly. The slider makes a slight change but I can do no local adjustments. All other parts of Camera Raw seems to be working. I have restored the computer. Is there a toggle I do not know about?

A lot more information about your hardware and software is needed.
BOILERPLATE TEXT:
If you give complete and detailed information about your setup and the issue at hand,
such as your platform (Mac or Win),
exact versions of your OS, of Photoshop (not just "CC", but something like CC2014.v.2.2) and of Bridge,
your settings in Photoshop > Preference > Performance
the type of file you were working on,
machine specs, such as total installed RAM, scratch file HDs, total available HD space, video card specs, including total VRAM installed,
what troubleshooting steps you have taken so far,
what error message(s) you receive,
if having issues opening raw files also the exact camera make and model that generated them,
if you're having printing issues, indicate the exact make and model of your printer, paper size, image dimensions in pixels (so many pixels wide by so many pixels high). if going through a RIP, specify that too.
a screen shot of your settings or of the image could be very helpful too,

Adjustment Brush not working correctly

Since moving to LR 5.6 the adjustment brush has not worked correctly.
I am unable to adjust the size of the brush using the scroll function on my Mac mouse.When I try to do this I can see the slider moving indicating the size of the brush but nothing actually happens.When I try to adjust it using the slider itself again nothing happens.
Has anyone else experienced this problem or can you offer some advise please

The ACR plug-in files for PS-CS6 and PS-CC are in different folders, but the camera profiles and lens profiles are in a common folder. Since updates to ACR are typically handled by the product, itself, not direct-link downloads that you must have saved for ACR 7.1, I don’t know what the error means in relation to CC having a newer ACR.
What version of ACR did you have installed for CS6 before you tried to update to ACR 7.1? Are you trying to downgrade from a higher version of ACR on CS6?
The first thing I would try is install ACR 8.3 RC for PS-CS6, using the CS6-specific link at Adobe Labs.
If you really need to go back to an earlier version of ACR, then the Adobe-approved method is to uninstall PS, entirely, then re-install it to get the older version.
It may be that you have to uninstall both CS6 and CC and then install CS6, first, and get it updated the way you want it, then install CC, again, and update it how you want it. That seems like a lot of work, though.
Why are you wanting to install ACR 7.1 for CS6?
If you plan ahead, then the way you can switch between different versions of the ACR plug-in, is to save your Camera Raw.8bi file each time you upgrade (I rename mine so the extension is the version: Camera Raw_8bi.71 and leave them in the same folder), and just replace whatever version of the ACR plug-in with that one you want.

Apple Mouse not working on Power Mac G4 MDD, works on other computers

I cannot get my standard Apple optical USB mouse to work properly with my Power Mac G4 (MDD). When I plug it in, the lights on the mouse work but the cursor does not respond. No movement, no clicking. However, when I plug the mouse into another one of my Macs, it works fine.
The Power Mac's System Profiler recognizes it as "USB Device," the mouse is unresponsive, and there are no mouse options in the System Prefs (keyboard & mouse). My Power Book's System Profiler recognizes it as "Apple Optical USB Mouse" and it works perfectly.
I am running 10.4.6 on both machines but I have had the problem with multiple versions from 10.3 up. I also bought another USB mouse (a Kensington) and had the same issues.
I've run through the standard USB troubleshooting like trying devices one-at-a-time and trying each USB port (on the Power Mac, the keyboard, and the back of a Cinema Display) as described in KB #300543 and KB #58033 but to no avail.
One thing that did stand out in #58033:
If the device shows up in System Profiler, even if the device doesn't work, the issue is usually due to software. Your best solution is to try updating the drivers, creating a new user, or reinstalling the system software.
Is there any way to update an Apple driver? I've only seen software for 3rd-party mouse drivers. I would try to create a new user but it doesn't seem to be possible using only keyboard shortcuts. And I would like to avoid reinstalling the system software!
Thanks for reading.

Have you tried other mice on your computer?
I seem to recall a problem like this when Speakable Items is turned on. I'm also going to dig into a little research on this.
Try checking that out. Make sure it is off.
The other things to try are logging in as another user and see if the problem remains. If so, there is a bad preference in your user preferences.
Lastly, if all else fails, try downloading USB Overdrive and see if it takes over the mouse function and provides you with a usable mouse.

Adjustment brush not working LR 5

Why isn't my adjustment brush working when it was working before. New LR version 5...had less than one month

Have you made any changes to your computer or updated the OS?
What exactly is happening when you click on the brush tool icon or press the K key to activate it?
If you press the O key to display the overlay can you see if the brush tool is making a mask when you paint on the photo?
Check that you have not set the brush to Erase ; click B for the standard brush or A for a brush with auto-mask edges.
Make sure flow and density is set to 100 unless you wish to gradually build up the effect (flow) or Place a limit on the effect (density)

Adjustment Brush not Working

in the Develop module my adjustment brush is not working, all the other sliders work, what is wrong?

Are you moving the sliders with the "pin" for your brushed area selected? When the "pin" is selected, it looks like a black circle surrounded by a very light gray circle and then a very thin black circle, like this:
What numbers do you move the sliders to?
Did you accidentally turn off the brush adjustments? The little doohickey highlighted in the red box, shown here, should be in the top position
Lastly, I am asking you to perform a very specific experiment, and report the results, and it does not appear that you have done so, or at least, you have not stated clearly that you have done so.
Please, click on "New" in the brush tool, then set Exposure to -4 and Flow to 100 and Density to 100, and brush. Report what happens.

I have LR 3.4 & 3.6... Adjustment Brush not working

I have LR 3.4 & 3.6... The adjustment brush is not working... I see people are having problems with LR 4 and are removing the preferences thing, but I don't see anything about LR 3 with this happening... I have it on my laptop and it doesn't work... So far the PC upstairs is still working... so not sure what happened on the laptop...
How do I fix it here?

There's no effect when I brush over the area.
I've tried exposure, brightness, teeth whitening and iris enhance... None of the changes they should make are showing...
I will try to remember to get a screen shot of the panel tomorrow when I've got the laptop again.

Adjustment brush not working in lightroom 5.7

The adjustment brush sliders don't appear to do anything anymore in Lightroom 5.7. Does anyone else have the same problem?
I don't need workarounds - this should work.
Thanks folks.

And- do you actually press or hold down the left-mouse button and drag the cursor on the image? as you would a paint brush. A 'Pin' will appear where you start the brush stroke.
And- Is it possible that you have the switch at the base of the brush panel sliders turned off ? (The toggle switch on the same line as "Reset" and "Close")

"O" does not affect any editing of the image.

Adjustment Brushes not working (3.0 & 3.2)

While processing some images the other night, using the adjustment brushes, burn, 3 large white squares appeared on the image for a few moments (5 seconds or so) before disappearing.
Since then, the adjustment brushes have no effect what so ever on my images?
Thanks
James

Hi James
After selecting the Adjustment Brush press O (for overlay) so show the area being masked.
You can then move the sliders e.g. exposure, saturation, clarity etc.) to adjust the masked area (usually shown as a red selection).
You can press O repeatedly to toggle the mask on and off.

LR2 Adjustment Brush not working?

I just got Lightroom 2 and have tried over and over to use the adjustment brush, but I haven't seen ANY results. A black circle with silver lining shows up where I click the picture with the brush. I have heard that clicking "O" makes the adjustment show up, but I've tried it and nothing happens. So, help! Am I missing a simple step or something??

Hi Emily,
One of the mask overlays that you get when pressing 'O' and shift + 'O' is clear and makes it impossible to see the results.
Press O to make the mask active and then press Shift O a few times to cycle through the masks.
If you put the exposure at -2 you should see the area darkening as you brush.
