Just got a refurbished 27" Imac I5 with the Radeon 4850 yesterday.This happened twice yesterday, so today, when I powered on I had my blackberry ready to record.As you can see theres a large green band (yesterday it was accompanied with a red one) that spans the vertical aspect of the screen. The bars disappear after 30-1min.I've tried searching and haven't found anyone with a similar problem. http://www.youtube.com/watch?v=mGK3LYb23mc
I've an early 2008 macbook Pro with geforce 8600 graphic cards.Since a few days i've problems with it, during a session my screen become a little green and pink and I've sometime the kernel panic message.When i restart, i've green and black bars on the screen, the apple is not in the middle and the mac freeze.I can't start with the recovery, even on the usb recovery disk, because after the choice of the recovery, the mac begin and freeze.I've ever try to begin in single user mode with fsck -fy command, sometime it resolve the problem but now nothing at all.
currently i have a blackbook and imac core duo, 17 ". My macbook beats the imac in everything except graphics. Before i got my imac i seriously considered a g5 dual 2.0, but the money wasnt there. I see an apple refurb dual 2.0 for 1599, and im sure i cud get one a lot cheaper used here or on another board. How much of a performance increase will i see IN APERTURE going to the PM, if any? i would need a good increase to justify it, and eve then im not sure my parents would be ok with me spending a few hundred bucks to upgrade
I recently read somewhere that I can actually change the graphics card on my mac. If so where can I buy the ATI Radeon 4850 graphics card? and how much will that set me back?And could I get this upgrade done by my local nextbyte retail store?If it is possible to have nextbyte upgrade my card would they send it off to apple? I really just need this card so I can play aoe3 on all settings high and be able to handle games like cod4, quake and all those graphic hungry games.
Twice in the last couple of days, these white and gray vertical bars/lines would appear on my IMAC screen. In between those times, my screen just went black, but I can tell the IMAC was still on, because it wasn't a pitch black as if the computer was off. Each time, the only way I could get the screen to appear back to normal was to turn off the computer and turn it back on?
This is not good. This is my second MAC. The first one after a year and a half, just poofed up in smoke. (Seriously, that is exactly what happened. I was sitting there, and all of a sudden the screen went black and a puff of smoke appeared from the back.) And now after owning this second one for almost two years, I've suddenly started getting these vertical white and gray bars and the black screen.
Anyone have any idea? I was simply looking up info on a website when these events happened.
Apple has been kind enough to replace my few week old iMac i7 with a new, refreshed model.I've heard that the graphics in the new iMac are discrete and separate from the motherboard.Does this mean the graphics card will be replaceable, albeit in a rather clumsy way?
My friend has the 24" white, 2.16Ghz iMac - spec http://www.everymac.com/systems/appl...nch-specs.htmlHe is currently running a fully updated install of Tiger, and running EyeTV v2.5.3 and VLC (unknown version). Here are the problems being exhibited:1/ When EyeTV is running, it will sporadically, and unpredictably, crash without explanation.2/ Many times, the iMac will not even boot - it gets so far @ the grey screen, and then the "Please restart your computer" screen pops up:3/ Also, when using either VLC or EyeTV, sometimes there are patterns of green *horizontal* lines, spanning the area of the video playback window (NOT the entire iMac screen) - this happens a LOT.I have booted in safe mode, verified the volume in Disk Utility, repaired permissions, and it still exhibits these same issues. Also, EyeTV will freeze when displaying video, quite often.
I did not use any program that would activate the camera, but the green light does not turn off. I tried restarted the computer and it is still on. I tried opening Photo Booth, and it said the camera is already in use by another application, but no other application is open.
I also have the same problem with the green text underline. I don't know how to get rid of it. How to get rid of the Downlite. The instructions are too complicated for me.
Is something like this decumented? I can still see everything on the screen, it's just extremely tinted green, and it's like that since the moment it boots up, even the first grey startup screen is green. I've tried calibrating
I shut my mac down 1 week ago. Apparently, it chose to restart. I am looking at an incomplete green status bar. I turned the computer off and back on. The status bar is stuck at 1/3. What can I do? I have no time machine backups.
I own a 17" g5 imac and today I was just browsing on Firefox and all of a sudden the screen became checkered with thin pink and white lines. It is most noticeable on the menu bar and anything that is grey or white in color. It is not checkered on the blue background behind my desktop photo. I have an external monitor plugged in as well and the same thing is happening to that monitor.
I have a powerPC imac G5 OSX 10.5.8 1.5GB DDR RAM ATI Radeon 9600
Here is a screen shot: Haven't reformatted it yet. Hope there is a better solution. Purchased it used about a year ago. No warranty.
We just bought a new iMac this afternoon. Haven't been able to connect to the internet, although the assistant says the connections are working fine. The ethernet light is green. Safari continually shows a message that says, 'your computer isn't connected to the internet."
Suddenly yesterday when I powered mi iMac I had some horizontal green bars on the startup screen then it powered normally. But it happened two times, now every time I power on my iMac the screen stay black, and i can use my computer, everything else is working normally (i still can use Alfred to turn off my computer).
I already tried resetting the Command+Option+P+R, it didn't work. Also the Safe mode.
New iMac at first of year has always locked up with green squares (1/4") randomly on the open window. I have to do a hard boot to unlock the screen. This may happen 5 or 6 times a day but I'm finding no pattern. It happens in any software, mail, internet browser, extra programs and only using what I need at the moment, including mail and internet, hasn't worked. I've run disk utility - repair disk and repair permissions multiple times to no avail. I've reinstalled the OS Mavericks and Adobe Creative Suite programs (Photoshop & Premiere Pro), no improvement.
I purchased a high-end iMac specifically to handle high-demand video editing needs. But this happens when checking email or browsing the internet too. Here's a listing of the system from a "Panic (system crashes) log" from the "Activity Report."
On my mid 2007 Aluminum 24" Intel Imac shows nothing but a white screen when powered on even though according to the diagnostic LED lights which are all powered on and green the logic board, video card, and everything else are speaking back and forth to each other perfectly fine. Does this mean the LED screen is bad or (from what I've read) is it a possibility the hard drive is bad? I know the optical drive is bad and will not spit out any discs. The #1 reinstallation disc for the OS is stuck inside right now. Before I order a new screen, inverter, and optical drive I figured I should ask in here to see if it is just bad hard drive or something else. Wouldn't the LED diagnostic lights tell me if the hard drive was bad?
I'm thinking of getting myself a Mac. I have not decided on much more than this. Well, a few things have been sorted. I'm either going for a MB 13" as a nice little e-mail and surfing companion or I'm getting the next iMac. If I would go for the latter then it would have to serve as a gaming platform as well and preferably for a couple of years.
Since gaming will be a good part of the duties performed by the dear little thing I must ask what we could expect in terms of graphics cards?
I'm aware that Apple often use last generation GC in their computers so a GeForce GT 120M is probably out of the question.
During the boot-sequence the screen of my Imac 27" flashes green (once), then returns to normal. This does not happen when I boot my Windows (Bootcamp) partition, so I assume this is some kind of OSX driver error. This started to happen only after I installed the latest patch (10.9.3). How to get rid of it ?
I recently had the 2.8Ghz 24inch imac with 2Gb memore and 320Gb hard drive with the ati graphics but had a display problem so returned it but my current pc is so slow i need a new computer now so i'm looking at the 24inch 2.66Ghz model but what sped difference will i see in sped from 2.8-2.66 and will the nvidia graphics be better, worse or the same as the recent ATI graphics and is the memore a bigger improvement with now 4Gb ddr3
with this talk of new imacs and mac mini's I thought it would be fun to speculate on what gfx card they may choose to include in the high end model. After a little searching around on what mobile cards are around my bet is on the Geforce GTS 160m. They seem to be going almost exclusively with Nvidia with the exception of the 4850.
I have a question about Mail. Whenever I try to forward an email, it forwards the text, but not the graphics! I am using Mail, Version 4.2 (1077). I've gone through the preferences, and cannot find a fix for this.
I was wondering if anyone could tell me how/if it is possible to upgrade my iMac 24" with an integrated nVidia Geforce 9400 to the dedicated GT 130 with 512megs. The nVidia website ([URL]) claims that the 24" model offers two potential upgrades (with one being the 120 and the other the 130), but doesn't specify exactly how this works. Does anyone know how to install this card? and what it would involve? I've heard the iMac is all but unupgradeable, but then I saw that claim on the nVidia website.
24" 3.06 NVIDIA GeForce 8800 GS Late 2008 I think?
BTW, the reason I am asking is because I am interested in this new Steam software that Valve is putting out and I want to know how well my Mac will do with the games.
Okay, everything's been working fine (except for that annoying high-pitched noise) but recently AirPort or whatever all that is has been really, really annoying.
All throughout today and yesterday I've never had a good connection, I'm right next to my router (it's not a problem with the router) and when I'm connected via Ethernet it's fine but I can't always be connected like that.
I'll try loading a website then the whole connection drops, multiple times. And when it's fixed, it happens again. and again. It's really quite annoying.
Also, I know NVIDIA GeForce 9400m is a GPU and all, but is there any way to upgrade the graphics? 9400m is absolutely terrible. Horrible. I can't believe they even put them in there to begin with. My brother's $500 dollar laptop can almost do better.
I started a thread a long time ago on using the iMac as a video editing machine, and the general consensus was that the only thing holding back the iMac from being an absolutely fantastic editing station was the graphics.
Now here's a question for the pros: now that the graphics have been updated for the 27inch (from Radeon HD 4850 to 5750) are some of these problems solved?
I'm planning on doing a lot of work in Avid, Final Cut, and Pro Tools, and I want to get to know After Effects well.
Will 8GB of Ram be enough for me?
Most of my editing will be off of footage from my 5D Mark ii.
Working in Excel today, I was highlighting groups of cells with color when the entire screen suddenly had a pale grey-green tint. Can still see colors beneath, but everything tinted (not just the Excel window, but the entire display). White, of course, is most dramatic. The Dell monitor beside it is fine.
I've recalibrated color a half dozen times (have always had to do that to get the Dell and iMac screens as similar as possible). It's impossible to get white on the Mac. Rebooted several times, including hard boot, zapped the PRam, ran Permissions Repair and Disk Repair from the startup CD. Installed Temperature Monitor to see if there's a heat problem, but I could not find normal temp values anywhere on the Web, so that was something of a bust. Temps attached below in case there's an educated set of eyes out there....
Ran some online tests, too, for color distortion, dead pixels, that kind of thing, but nothing reveled.
I've been all over the Web looking for some guidelines, but most posts at apple and elsewhere seem to focus on later-model iMacs with the yellow lower screen problem when new (It's not that) or panic screens of wild colors, stripes, and the like. This is just a grey-green tint that covers the entire screen, rendering whites grey-green and colors muddy.
Am having a problem with the screen getting "messed up" is the best way that I can describe it. Happens with all different apps running but nearly always shows up when trying to edit a photo in iPhoto. When I make an adjustment there (like sharpening) the photo will turn all red and the system will lock up. This does not always happen, but just most of the time. In other apps, it can result in just messing up that page or the entire screen. I can replace the Graphics card myself if that is what the problem is but is there any way to test it before laying out the $250?
