Is the iMac really capable of high power use?
My 3 month old iMac is in the shop because of random shutdowns - mostly when I use Adobe Photoshop CS3 (but also when I am just reading email or browsing the internet). The "Apple Tech" informs me that perhaps the software I am using is too much for the iMac (set up with 2GB of memory, 20" model). Is it just me or did I misunderstand the ads and sales folks when I read and was told that this iMac was for me and my 10 megapixel digital camera coupled it photoshop (and the list goes on)?
Yet, Apple support told me to take it in so that it could have its power supply or logic board replace because one of those is possibly the problem.
Anyone else have an iMac behaving like a lemon when you put the pedal to the metal?
I don't have this problem with a 1.5 year old Mac Book running the same exact program.
At work I have 2 computer labs of 2.16GHz iMacs/2GB RAM running CS3 apps daily without any problems. It sounds more like manufacture defect to me.

Which iMac usb port is high power?
Which iMac USB port is high power?
I'm not sure this is the case, at least on the newer iMacs. Some ports will adequately power some devices (most notable the USB Suerdrive) while others won't. Or, this has been the case recently, anyway; USB with Apple devices seems hopelessly arcane anyway, which makes no sense at all!)

Is the iphone 4s capable of data transfers using 4g or is 3g the only option with this phone?
The iPhone 4S supports HSPA+, which is defined as "4G" by the ITU. It does NOT support LTE as it lacks the hardware to connect to an LTE network.

HT201343 Controlling the iMac desktop from a different room using mirroring (mouse/keyboard)?
How are you meant to control the imac desktop from a different room using mirroring (mouse/keyboard)? Is there an app for that? Or a solution?
Tried the trackpad out in the lounge and it worked, it's a little less responsive, but a far cry better than using McTivia with usb bluetooth mouse and/or keyboard. I guess the airplay mirroring is at the stage of an add on gimmick. Perhaps in the future AppleTV versions will come with bluetooth support to allow for serious use of the mirroring, especially with gaming. Thanks people!

Should the FW 400 port be sending power to the FW HUB When the Mac is off?
The title says it all. I am using a refurbished 2007 Aluminium 20 inch IMac and after I shut down the Fire Wire ports still power the FW 400 Hub, is this normal? I have just stopped cutting power supply with surge protector because I was having trouble getting the Imac to start and leaving its' power supply on made the start up faultless. Could the "shut down" instead of "log out" be the cause?
Hey JustSomeGuy, thanks for solving the problem. The "cause" you were curious about is the choice when stopping to choose "shut down" instead of"log out", I'm not sure what the second one[log out] would do when I wanted to start the iMac again.
PS: my USB peripherals don't get enough power when the iMac is off to have them show lights indicating power, but I believe you are right. When I had the iMac in a surge protecter, so it was cut off completely from power it had BIG problems with starting up, for some reason the iMac must have access to power to always start up as it should. -
How Long Does the iMac's Battery Last
Hi. How long will the iMac's battery last if you use it 8 hours (how about for 16 hours) a day and shut it down when you go to bed.
Thank you in advance.
Gbu.As long as you leave the machine plugged into a live power source, even when it has been turned off it will still draw a bit of power to maintain PRAM and the clock chip, and will not use the battery.
The battery is used only when there is no othe source of power available. And, it is not recharged in the iMac. -
Anyone have trouble with sharing internet by Airport from the iMac?
I was using my 20" iMac as a transmitter for our internet connection and we started to see the strangest problem. The iMac would continue to indicate that it was transmitting, but the signal would disappear on the end of the 12" powerbook, TiBook and iBook that were using it.
The iMac was not going to sleep - was set to never sleep - continued to have a working connection, continued to indicate it was transmitting, but the shared connection wasn't visible on the list of either powerbook.
Turning airport off and on in all the machines didn't help, stopping sharing and restarting it didn't help. But then suddenly the signal would show up again sometimes in 10 minutes, sometimes in an hour.
Tried using all different sorts of levels of encryption, including no password - same problem.
We're currently using an Airport Extreme base station with no problems, and have used a linksys router with no problems. The hardware test indicates no issue with the iMac airport and the iMac is capable of joining and maintaining a connection with the airport express base station or the linksys router without a problem.
It seems to only have a problem when it is hosting the wireless network. (This issue is in addition to the slowness of the iMac airport connection, but that's a different thread)Never had an answer to this - just stopped using the Airport on the iMac. For now, I'll mark this as answered.

For some strange reason if i attach my 2 apple cinema displays to my iMac to make a triple screen set up msn messenger video chat does work but it uses the apple cinema display inbuilt webcam and not the iMac webcam. Its annoying as i have to turn sideways to get into the video call view.
So i have a set up like this: an apple cinema display thunderbolt, then in the middle an iMac new then to the right of the iMac another apple thunderbolt cinema display. WWhen i use MSN messenger to make a video call it uses the inbuilt webcam on the far right apple thunderbolt cinema display and not the inbuilt webcam in the iMac in front of me, its annoying any ideas please.
If i unplug both side cinema displays MSN messenger uses the inbuilt camera on the iMac like normal but when i use extra screens it uses the webcam built into those and not the iMacs webcam.I would try with another client like skype or something
and if it's only msn messanger which have the problem it may
be more of a question for ms's forum? -

Using the IMac 27 only as display for MacBook Pro
Hello,
i like to use my iMac 27 only as display for my MacBook Pro.
I have the connecting cable.
I must start the iMac, he is booting and then i can plug in the cable to my MacBook. Now i have the second display for using with my MacBook.
Now my question: Is it possible to use the display without booting the iMac-system?
Thank you for help!
Best wishes

Fellow Mac enthusiasts,
I am currently playing Xbox 360 on an old CRT moniter next to iMac, using a vga adapter. The Problem is I dont have any sound. So in theory couldnt i plug in the the digital audio cable that comes from the 360's Sound ( same size as the audio in port on the iMac/iPod headphone size) into the iMac's audio in slot, usually used for microphones, but just plug it in and use a program to just play the sound? Get what im saying?Hi Gamedude6
Yes just be sure that you are using a 3.5mm stereo jack in the Mac like the one in the link below.
http://www.maplin.co.uk/images/Full/ck27_2003cat.jpg
Then have a look at this handy little app. call LineIn from MacUpdate for passing the audio from input thur to output.

My iMac wouldn't turn on. This has happened out of nowhere, it was working really well before. checked my power cord and outlets everything's fine. The iMac has no power at all. no sound or anything, completely dead. It is only 1 year and 2 mos old. Any idea what it could be?
I have purposely been ignoring your responses to my posts about the heat issues in the newer design iMacs, but if you want really want to ague the point...
First, the iMac is marketed as a desktop model Mac. Not a laptop or MacBook.
I have never owned a MacBook, so I can't attest to how much heat the MacBooks generate.
I Have two iMac models. A 2009, 27 inch screen iMac for myself. And a 2010, 21.5 inch screen iMac for my Fiancée.
As a desktop Mac these are hottest running desktop Macs I have ever owned. Period. I owned two beige Macs, a pre-G3 tower, aG3 desktop, a G4 MDD Tower, the original iMac, eMac, iMac G4 and now my current iMacs.
None of my previous Macs have ever, EVER ran this hot. I have never, also, had any component failures in any of the previous Macs I have owned, either. All of my Macs have been upgraded or modded to some degree over the years. About 2 years ago I had to press my old G3 back into service. Both my G3 and G4 models have been heavily modded. The G3 ran without issue for a close friend for over a year until that friend went out a got a Mac Mini.
That's a 1996-97 Mac my friend. And it still is in working order and hasn't had any failures.
The fact I am pointing out here is that heat is an enemy to electronic components.
Whether desktop iMac or MacBooks, tightly packed enclosures of heat generating computer components with fans that do not run fast enough at most times to cool off the interior or exterior, will and does slow roast computer components to premature failure.
I do not know how frequent component failure is in the MacBook line up. So I can't attest to those.
I do not participate in those forums.
This is why at some point in computer history, Super Conputers were liquid cooled. PowerMac G5 systems were liquid cooled because they ran too hot!
I have taken my own precautions to keep my iMacs' heat down as much as possible.
I don't have the money to keep buying a new Mac every 3-5 years when some catastrophic failure happens.
I had to purchase my iMacs used as I couldn't afford the cost of a new iMac with the specs I needed.
My idea, your idea and Apple's idea of acceptable operating temps we can argue all day long.
I feel, personally, that the operating temps are too high and exacerbate operational issues.
I Have been participating in these particular iMac forums for just over a year and have seen plenty of posts of iMac component failures due to both heat and dust, dirt issues from within the iMac.
There can be no other reason for all of these failures. The SuperDrive is, usually, the first to go bad.
It's probably due more to its vertical mounting, but the excessive interior heat isn't helping it.
Next to fail is the GPU. The last to fail, but the most expensive to fix, the Logic Board.
I Have seen plenty of posts in my last year here of all of these failures in iMac less than 5 years old and ,perhaps, a little older. 2008 model iMacs seem to have their issues, too!
Apple is focusing too much on design and aesthetics, rather than longevity of their products, I feel now.
A Mac isn't going to last 7- 10 years anymore.
I don't have stats and numbers. Just common sense.
This is my story and I am sticking to it. For what it's worth. -
i have an imac g4 purchased Dec 2003 runnung OS 10.5.8. It runs fine with airport off, but when I turn airport on it freezes with the black page, "restart by holding power key . . ." I swapped the airport extreme card with the one in my ibook G4 (purchased same date and running same OS). No change in operation.
I am running wifi from verizon. Recently changed from mifi2200 to jetpak 4620 in a 3G location. Ibook running fine, desktop freezes. If I can boot desktop in safe mode and get airport turned off in time. then I can reboot regularly and imac runs flawlessly with no wireless.Have run disk utilities and TechTool Pro rebuild etc, but nothing has worked. How do I fine the culprit?the power logix thing was really sad. apple changed so much after 10.4.8 that there wasn't a viable way to patch the software.
That statement is precisely why I don't believe in blindly updating the OS, especially in a non-standard machine.
We can't expect third parties to support us forever, and it is shameful to break something that works fine, except that we updated the OS....
I think that any upgrade or modification to a machine or the OS greatly increases the risk of trouble or incompatibility with current configuration and "new" system files.
After all, the component or software could only be tested as far as the current OS version when the component or software was released.
Beyond that, we are all "beta testing".
Following a beta tester protocol, and applying updates to a cloned system drive first, is a prudent way to approach updates, and not only for older, heavily modified machines.
After 10.4.8 and moreso with Leopard, the focus is primarily on Intel architecture, not PPC architecture.
Like it or not, we are all updating to the abyss of the extinction of our machines, unless we can be satisfied with the last stable version of OS that works well with our hardware and software.
I wish they would include the latest pkgs at least with software update.
Yes, having individual packages, rather than lump "OS X 10.x.x" updates would be nice.
This way, one could update as one sees fit. That is to say, for example, fix the Quicktime, but leave my Network alone, etc., etc.
In all fairness, Apple does provide for some breakdown of updates, but I believe there is much room for improvement, especially, as you point out, with regard to the core services portion of the OS.
Until then, I'll leave Software Update disabled....... -
I am trying to upgrade two MACs to Maverick. I have been successful with My Power Mac but unable to get my Imac to load. I am running Snow Leopard on the Imac. When I go to the App Store it shows that it has been downloaded. Any ideas? Any ideas
You stated; " I have been successful with My Power Mac "
A Power Mac is incapable of being upgraded to Mavericks. It is a PPC Mac which can only run versions of OS X up to 10.5.8 and no higher. Any version of OS X higher that 10.5.8 requires an Intel processor to run.
Does the iMac meet the hardware requirements for Mavericks?
