IMac :: Using 21.5" Airport Graphics?
Jul 12, 2010
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.

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

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.

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?

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.

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.

How can I tell?
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.

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.

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?

I'd like to start by saying excuse the stupid questions, I'm still very new with using macs. I'm a long time PC user, but I've recently made plans to replace my PC with an iMac. Specifically a 21.5" with an Intel i3 processor. This mac comes with 4gb ram, and a Radeon 5650 HD graphics card.
Now I'm a fairly big gamer, and I like my hardware to be as high-end and up-to-date as possible. If I were to plan on upgrading the graphics card, ram, and processor, could this be easily done at home?
I'm asking because of the unusual structure of the iMac. i.e. the lack of tower, and all the hardware being merged with the screen. I'm assuming it would be a lot easier on a mac pro because it actually has a tower that I can easily open/customize.
Lastly, granted that the above is possible, are the generic graphics cards, processor, and ram chips compatible with iMacs? Or would I need to buy a special iMac compatible version from an Apple specialist shop?

I just got an i7 27" iMac, and while its wonderfully in every way imaginable, I have an issue with my graphics card or drivers or something.
Two examples proving an issue:
I run world of warcraft and look in the video settings and I can't set anything to max at all, also a red bar assuming my graphics card is way out of its depth or something.
Also tried to run Left 4 Dead 2 from steam and in the menu I get some images come up as pink checkered squares and it always freezes when loading a match.

My 3 yr old IMac G5 (no isight) seems to be real sluggish in graphics dept. I never used to have problems watching hulu videos, now they stutter. When I play warcraft, the game struggles to keep up if I'm in an area where there is lots of players. Would a new graphics card help? Is it replaceable on my IMac model?

I want to use a windows Driving Simulator on my iMac, probably using Bootcamp. The system requirements are
Graphics - Any 64MB 3D graphics card or above*
*NVidia GeForce FX or higher / ATI Radeon 9500 or higher. Laptop versions of these chipsets may work but are not supported. Other integrated graphics chipsets are not supported.
I have an 20 month old iMac with a ATI Radeon HD 2400 XT. Will that do? I have absolutely no idea about this stuff!

It only took me a year to figure it out, but I've confirmed that the problems I've been having for the past year with the screen freezing (thought the computer was freezing) are owed to a bad graphics card. The card I have in my 2.16GHz 24" iMac (purchased Sep '06), NVIDIA GeForce 7300 GT, is indeed ready to die. I found some articles that said the graphics card is easily upgradable in my iMac. If true, which replacement card should I buy? And is this something I can install myself, simply by removing the cover, pulling out the old card and installing the new?

If there's no refresh this coming week, we're pretty much going to be forced into settling for one of the 27" iMacs (we're on our third) and hooking up a second (probably 24") monitor to do color sensitive work.
Does anyone out there have a dual-monitor setup running with the 27"? I was wondering if you notice any sort of graphics performance hit with the second monitor attached.

Im having my first ever problem with a Mac, bummer! I have tried Googling an answer, but didn't find anything specific enough for my situation.Last night I installed the SL Graphics Update, hoping to be able to run Starcraft 2 on a higher setting.
Anyways, I installed it, and now the computer wont boot. It is stuck on the gray screen with the spinning symbol. It appears to be installing the software update, since it shows a gray progress bar, but then once that finishes, it just stays on the gray screen with the spinning symbol and goes nowhere after that.
I have a Macbook Pro available to use, if I need to target the disk. Not sure how to do that though, just found that idea in my google search.
I have no problem just being able to grab my important data off of it, and starting on a fresh install. I just dont want to lose my huge library of pictures and music.

We're running an IMac G4, 700 Mhz, 768 Mb Ram with OSX 10.3.9. We have been having a problem with freezing/crashes for a long time, accompanied by distorted graphics and have been unable to get to the bottom of it. A screenshot of what happens is linked below. The pattern is that we will start working on something, then the graphics will become distorted in a small area. Then sometimes we'll get away with working for a bit longer, or sometimes it goes wrong right away. The graphics distortion spreads, and either the computer freezes and has to be restarted or we get the grey error box saying to restart. We've tried: adding more ram - it still crashes even with simple apps. using macaroni to schedule maintenance tasks unplugging hardware to see if there's a conflict. Have also tried clearing the PRAM on reboot, which seems to increase the chance of it working for a while.

Sometimes when i log-out it takes a lot longer than normal it shows the blue screen and spinning gear then it seems like the computer just freezes like the graphics have messed up. Then a few minuetes later the login window will appear as normall like nothing has happened.
Do you think i should take this imac back or do you think its just some software bug?

it appears my graphics card on my old iMac G5 is toast. I took it to the Apple Store and they said they'd have to replace the whole logic board for around $680. After searching around this forum, that does appear to be the only fix. My question is this: is the graphics card on the newer iMacs soldered into place as it was in the older iMacs (G5 and I believe the first gen Intels as well)? Because, if so, that is really lame and may affect my computer replacement decision.
