Display and Layer Corruption

Installed the new 2014 CC Apps yesterday (very exciting!!) and started doing some real work in Photoshop CC 2014 today...at some point i tried to darken a white layer with "Brighten and Contrast" but saw my white layer get filled with mostly black and gray artifacts, which i wasn't able to eliminate in any way (hiding and re-enabling the layer, hiding the tab and opening it again, minimizing Photoshop and opening it again, etc.)...suspecting an OpenGL display problem, i opened the file in the Save for Web module, but saw the same layer corruption in there...i saved the document, closed and re-opened Photoshop and that document, and the artifacts were actually saved into the layer, eliminating quite a bit of my work.
I am all but certain that this is an OpenGL or GPU related issue...i have long suspected that this particular Retina MBP (mid-2012) has some unresolved GPU issues...have any of you experienced any similar or related issues?

John, when you link to an issue in Adobe Elements 11, how does that relate to my issue in Adobe Photoshop CC 2014, which doesn't have a HandlerTimeline.Framework , which appears to be the cause of the problem you linked to.
in this thread you linked to, someone says it's "a known issue with Retina screens", so are you also implying that this is a screen issue, or an issue with the Retina model of the MBP? does the Retina screen itself have hardware that would cause this, where the non-Retina screens do not have this problem? how could this be? is there a frame-buffer or something like that *in* the screen? i have had mine replaced a few months after buying the rMBP, due to the burn-in issue, and then again when that screen started to develop bad pixel clusters, so i hope this isn't a hardware-resident issue.
wouldn't this be more consistent with issues within the GPU, maybe caused by over-heating or nVidia driver bugs?
do you have a link to more info?

My word files are all corrupted- when i open 'get info' under "More info" they all have 'Photos for Personal Use or Home Display" and Authors: technology

My Word files are corrupted. When I open 'Get Info' then 'More Info' I find 'Photos for Personal Use or Home Display' and 'Authors' : Technology. - Nothing to do with the file I'd just written. My most recent files can't be saved or opened.
Is this Malware or some other kind of attack? I grabbed photos yesterday from what seem to be freely available pictures online. I discovered Firevault and Firewall were both turned off. (I hadn't checked before.) Any suggestions?

Apply the two fixes below in order as needed:
Fix #1
Launch iPhoto with the Command+Option keys held down and rebuild the library.
Since only one option can be run at a time start
with Option #4 and then #1 as needed.
Fix #2
Using iPhoto Library Manager to Rebuild Your iPhoto Library
1 - download iPhoto Library Manager and launch.
2 - click on the Add Library button, navigate to your Home/Pictures folder and select your iPhoto Library folder.
3 - Now that the library is listed in the left hand pane of iPLM, click on your library and go to the File ➙ Rebuild Library menu option.
4 - In the next window name the new library and select the location you want it to be placed.
5 - Click on the Create button.
Note: This creates a new library based on the LIbraryData.xml file in the library and will recover Events, Albums, keywords, titles and comments. However, books, calendars, cards and slideshows will be lost. The original library will be left untouched for further attempts at fixing the problem or in case the rebuilt library is not satisfactory.

Display and lock up problems with 3 week old MBP!!!

Hi all,
I hope that someone here can help with a scary problem that I have experienced with my (otherwise perfect!!) MBP!!
Occasionally, so far always after a boot up or wake up (but never on the login screen!), the MBP will lock up completely and the display will become corrupted as in the images I have posted below (fingers crossed!)!
As I said, it locks up the MBP so that the only action I can take is to force a reboot by pressing the On/Off button for the required amount of time.
I took the MBP to an Apple shop after making an appointment with a Genius (wonderful, lovely Spanish girl, name of Eva!!!!). Sadly, as the symptoms could not be recreated in the shop there was not a lot Eva could do, she did recommend a re-install of OS X, and also suggested that I let them have the MBP for a day so that they could hook it up to something (for a full eight hours!!) or other and test it. Eva did say that she had not seen the problem before (I took my camera to the shop and showed her the pics of the screen), but that it did not look good!!
So, I decided to take it back home and ask for help here!!!!
Any advice would be welcome!!!

i would go back and show them these pics, also try doing stuff that is graphics intensive, my guess is that you have a bad video card, doing things that heat it up should get it to happen
one thing that you can use stress the vid car is the opengl example programs included with XCode (its included with the programs on the CD that came with the computer), so i recommend opening a few of those, and then doing a few `yes>/dev/null` in the terminal, also make the window semi-transparent, and put it on top of quicktime playing some movies, that should help stress the video card and put extra heat on it
if you can get that to consistently cause the problem then take it back to Apple

External display and sleep issues

A 15-inch MacBook Pro worked fine with an external display and keyboard prior to the 10.5.2 update. After the update the external display goes dark when the laptop is closed. Hitting the external keyboard momentarily wakes up the external display but then it almost immediately goes back to sleep. It's as if the MBP thinks it's in battery mode and not plugged into an AC outlet.
All Energy Saver settings are to keep the display awake. Could this be a corrupt driver or some other issue?
Thanks.

Theres been a lot of disscussion about this and it's a BIG problem. Check this out:
http://discussions.apple.com/thread.jspa?messageID=6597635&#6597635
http://discussions.apple.com/thread.jspa?messageID=6669894
A lot of us are having the following problems after the graphic update:
-not waking from sleep (waking, but display staying dark, restart is only solution)
-not being able to use in clamshell mode (with external monitor)
-not being able to run external monitor at full resolution
I've also had some weird bugs like the settings and calibration of my external somehow coming over to my MBP monitor after disconnecting the them.
I hope Apple can fix this.

ITunes Won't Quit And Appears Corrupted

When I quit itunes it restarts again with the dot under the itunes logo but the iTunes window doesn't open until I click the icon on the dock. Also in the middle of the size value in the size column the value starts with a number then in place of a decimal point I see a reverse video "?" then the rest of the number. Also the files will not alphabetize correctly no matter which column I choose to alphabetize. The program seems to work erratic and sluggish as well. The way I fix it is to restart the machine but this doesn't always work. Even after I get iTunes to display and work correctly and it's sitting open the problem described above will reoccur. I think a file like a PLIST is corrupted and am willing to trash it if I knew which file so long as I don't lose all the time I've sent in getting the right artwork and building playlists. I've been using this wounded iTunes program for a couple months now and am getting really frustrated with it. Any suggestions to fix it?
Thanks In Advance For Your Help!

Looks like I figured out the answer to my problem. I've been using the Logitech squeezebox products on my network. With their squeezebox server program that is installed on the mac they grab the location of the iTunes library to stream the music to the various squeezeboxes on the network. My corruption problem with my iTunes library coinsided with installing the latest version of the Logitech squeezebox server 7.7.1. While my iTunes library was acting up so were my squeezeboxes. They would quit playing the music or has long delays before playing. Checking on the Logitech forums they reccommend when experiencing problems after an update to do a clean install deleting all the old Logitech files sprinkled throughout the hard drive. After doing so the my squeezeboxes started working again. I also noticed my iTunes library was no longer corrupted.
I will continue using the squeezebox products because they are, and I have a hard time saying this, better than the Apple Expresses or anything else Apple has created with regard to streaming. They really shine when you buy the iPeng iOS app that will let you stream your music library to your idevice not just on your local network but anywhere around the world wherever you have an internet connection!
Remember on the 3G network this will eat away quickly at your data plan allowances.
Hope this helps

Saving image and layer separately with transparent background

I have a photo with a layer and I am trying to save two images (main photo and layer) with transparent background. I am able to save the main photo with transparent background but somehow not able to save the layer with transparent background despite selecting the option while saving as PNG. Any help will be appreciated?

OK... I'm probably not being clear.
When I import the PDF, I get a typical architect's line drawing as shown below. So the background is displaying as white. In Corel, when you save a GIF or a PNG, you can specify that -everything- that is the 'background colour' is rendered as transparent. IOW: there's no need to erase the 'white' pixels; they are auto-magically converted to transparent.
But in PS (CS4), no matter what I try, the rendered PNG or GIFs show as white, rather than transparent.
Is there a way to have this same behaviour in PS? Or do I first have to use the erase or background erase tools to get rid of the white?

24-inch Cinema Display and Mid-2010 Macbook Pro - Cinema Display still flickers after updates

I currently have a 15-inch Macbook Pro (mid 2010) hooked up to my 24-inch Cinema Display. I have updated all the firmware for both the Cinema Display and the Macbook Pro but still get intermittent flickering. Moreover, I have cleared the PRAM and VRAM. I have done ever possible update I can find, the system is fully functioning. Help?

I am having this exact same problem. 2010 iMac with NVIDIA GeForce 9400 256MB. I have it hooked to a 30" display through a DisplayPort to DVI-D adapter. The 30" is fine, but I have graphical corruption constantly on the main iMac screen.
This all started as soon as I updated to Yosemite a couple days ago.

Messed up color display and resolution because of mini-DVI to video adapter

Once I connected the mini-DVI to video adapter to the tv and got weird colors on my screen for a while but then it worked out, then after a while I disconnected the cable and turned my computer off. After that, everytime I turned my macbook on, the color is fine for two seconds and then it turns into a weird offset color, really bright colors, kinda sketchy and just a few colors, and a weird resolution and display obviously, but then I just connect my Mini-DVI to video adapter and disconnect it again (quickly) and the color returns to normal. How can I make the normal colors stay and not have to connect the mini-DVI to video adapater everytime I want to see the normal color display and resolution??
please help!

Open the Universal Access pane of System Preferences, click on Seeing, turn off the White on Black, VoiceOver, and Zoom options, and drag the Contrast slider all the way to the left. If the issue persists, create a new folder on the desktop, drag half of the items from the Library/Preferences/ folder of the item in the Finder's sidebar with the house icon into it, and narrow down the files until you've isolated the one responsible.

Dual display and VRAM usage.

Hi, back in the days I wanted a 12" iBook but couldn't afford one, last autumn thought I decided to get a Macbook Pro, the update came and...
.. it had 128MB vram.
I want to use dual screen and maybe even occasional gaming, I couldn't decide if this where sufficient for my needs or not so I waited for the june update.
The mid-07 MBP arrived and, it had 128MB vram AGAIN!
Why oh why Apple? Oh, don't answer that, it's because you're in bed with Intel and want to force feed us useless highest end CPUs. But all I care for is the VRAM, why do I have to pay a ****-of-a-lot for a 1/11th faster CPU?
Anyway, I tried to decide if I should "bit the sour Apple" and get the mid modell or just get the low one because that one is much more price worthy. A few days ago I ordered the low end one.
But then I've seen on barefeats that he says that a 30" ACD display would use 128MB vram of the 256MB vram modell, are vram always splitted between displays in OS X?
You see, if the extra 20" 1680x1050 display only use 1680x1050x(3 or 4) bytes that is ok, maybe even if it's double buffered (is it?), because then I will probably have like 100MB vram left for all my windows and for desktop usage that is probably ok. But if the vram is shared between displays and my 20" which I will use most only get 64MB vram that's quite low.
I know I can turn of the sleeping capabilities of the MBP and shut the lid and only use one screen but that's a quite lame solution.
I hate how Apple does this, and it seems to worry a lot of people. Some get the more expensive modell and hate that they had to do it, some doesn't, and some don't buy a machine at all .. I would probably have stayed in the last crowd.
256MB vram can't have cost them many tens of dollars, why not have that in all modells? Why is the middle one even needed? Just make 2.4GHz CPU and option in that case.
Anyway, does anyone know how much vram my screen will have available? Will 128MB work for me with all the regular desktop apps I will have running? Or should I really go with the 256MB one? The tricky part is that my MBP might be shipped today or similair.
I've called Apple support three times but noone of them knows how this works so they aren't for much help.
(Dell vostro 1500 sells here in Sweden for less than half the price of the mid MBP and comes way more balanced, you can even get a 1680x1050 screen. Sure it has 2.0GHz CPUs or whatever but I don't care about that. Where is the old "omg MHz myth"-Apple? Please understand CPU speed isn't everything. Instead of leading the MHz myth fight it ;D, start calling the CPUs T7300 and so on aswell ;D)

Hi Johan, actually the VRAM used by OS X is likely to be quite a bit more than just your screen resolution multiplied by 3 or 4, since each open window is composited offscreen for the shadow effects and for things like zooming (Ctrl-Mousewheel) and the "Genie effect".
I'm pretty sure the total VRAM isn't divided in half for each of the two displays though, as it will be allocated from the video driver on an as-needed basis. In practice, with both displays active and a few windows open, you should still have maybe 80-90% of your VRAM available for applications.
Games and other VRAM-heavy applications are a special case as these will typically use as much VRAM as you can give them, and swap out to system RAM via the PCI-X bus when they need more (and unlike swapping to disk, swapping into VRAM from system RAM is still pretty fast).

Horizontal shifting bars on MBP 15 after disconnecting 24" LED cinema display and waking up from clamshell mode.

I use my MBP 15 (late 2011) with 24" Apple LED Cinema display in a clamshell mode. After disconnecting external display, and opening display, it shows horizontal shifted bars, so it becomes completely unusable. Have to hard reset laptop. Any hints on how to resolve this? Thanks.

Ok, more information for anyone that might care. The wake-up seems to be the familiar dark wake in order to go into hibernate mode. Except now, it's a death wake. Looking at the logs, I see that it happens exactly 70 minutes after sleeping, even though hibernatemode = 0 (which shouldn't hibernate at all!)
So my power settings look like this:
Currently in use:
standbydelay         4200
standby              1
halfdim              1
hibernatefile        /var/vm/sleepimage
darkwakes            0
gpuswitch            2
disksleep            10
sleep                10
autopoweroffdelay    14400
hibernatemode        0
autopoweroff         1
ttyskeepawake        1
displaysleep         2
acwake               0
lidwake              1
standbymode is 70 minutes, what a coincidence. I'm going to try setting it to 0 and see what that does.

How do I use my iPad as the display and input device for my Mac Mini?

I plan to have the following stereo configuration:
Integrated amplifier with USB input that supports up to 24/192 audio, the Peachtree Nova 125
Mac Mini with USB connection to amp, wifi to the Internet, housed in the equipment cabinet with the integrated amp, no other music source. No display or keyboard connected to the Mac Mini.
I would like to use my iPad as the display and to control the Mac Mini to run Pandora, iTunes, Spotify, podcasts, etc.
Anyone have success with this general configuration?

You need a set of apps (one for iPad and another for computer) like Team viewer or Go to my PC

Can a Mac Pro (2.66 ghz duel core) be upgradable to support Thunderbolt displays and other devices.

Can a Mac Pro (2.66 ghz duel core (4cores)) be upgradable to support Thunderbolt displays and other devices. Does this need to be done through the Graphics card expansion or a additional card to be inserted?

No. There is no way to upgrade any Mac Pro older then the cylindrical 2013 Mac Pro to ThunderBolt.
The requirements of Thunderbolt require a totally redesigned motherboard and chip set rather any plugin cards. These motherboard were never developed for older Mac Pros.

How to connect a 23" Cinema display and mac mini to an AV Receiver?

I am trying to get my 23" Cinema display and Mac Mini to a Yamaha RX-2700 AV Receiver. I am on first name terms with the guy in Maplins because I tried to get an Xbox 360 working with this display before and gave up in the end. The AV receiver has upscaling capability so I thought I'd try again. I tried connecting a HDMI - DVI adapter to the HDMI Out on the receiver and a HMDI to DVI cable from the Mac Mini to the HDMI in with a optical cable for the sound. The sound works fine but I get no display - the LED on the monitor flashes three times with a blank screen so it can't read the signal. Another option suggested was to use a VGA Converter connected to a VGA - HDMI cable but I would like to find out if that would work before going down that route?
I am looking for some advice about whether this type of configuation is possible with the 23" ACD and if so what do I need to buy to make it work? I love the quality of my ACD to avoid having to replace it with a TV to get my multi media life in order.
Many thanks

How to connect a cinema display and a VGA monitor to mac mini

I bought a Macmini and want to connect to a cnema display and to a monitor that uses VGA connection. I also bought a MiniDisplayPort to VGA adapter but the MacMini only has ONE Minidisplay port. I thought this would be more straitforward....

I'm unsure of the issue, the Mini has both mDP and HDMI outputs, right? If so, the mDP for the Cinema Display an a HDMI to VGA adapter for the 2nd monitor.
