Mac Mini :: System Overheating And Shutting Down
Jan 14, 2010
I've googled to see if I can find a solution to this but not had any luck - wonder if you could help. My Mac Mini is 1.5Ghz PowerPc G4, 512Mb RAM, running Mac OS X Version 10.5.8. I bought it second hand a couple of years ago and in the past while it's really been playing up a bit. It first started overheating and shutting down when I was doing really resource intensive stuff - for example, opening a large amount of RAW image files. However, it's now started taking to shutting down when I'm doing normal browsing, using Spotify etc The machine also tends to hang a lot, and I can't really stream videos very well either. The vents at the back of the Mac definitely aren't blocked and there's plenty of space around the machine to let the air circulate.

My Macbook is 1.5 years old (13in, white, 2 GHz). About two weeks ago, it would randomly shut off. It would restart fine, but shut off sooner. Sometimes, it wouldn't even restart. Now, it's at the point where when I power it on, it rarely restarts past the white apple start-up screen.
My thought is that it is overheating. Are there any more ideas? What can I do to save my macbook?

I've got an early 2005 model Power Mac G5. Bought it from a hospital and it's really clean inside. Lately it's been shutting down spontaneously without warning. I thought it might be an issue with overheating, but I'm not that familiar with normal heat levels for a CPU. I installed iStat nano and checked the temperatures. I took a screen shot of the widget. Temperatures are in Fahrenheit. Can anyone tell me if I'm on the right track? What do I need to do to solve this problem?

over the past few weeks my blackbook has been shutting down more and more frequently from what I can only believe is overheating. I just checked my computer upon startup with SMC fan control - it starts up at about 70 C and at about 3500 RPM. Yet, after a few minutes, the fan immediately drops down to 1100 RPM or and fluctuates between 800-1400. I try to force the fans to spin with SMC Fan control, but nothing happens. I've looked all over the web and I can't find anything definitive. I know that macbooks tend to overheat. What can I do?

I don't know if it is a fan or a drive that starts up and runs really fast and loud, then the computer shuts off. I always thought it was the fan, but now am not sure. I have moved it to a place where it is exposed to more air, but that has not seemed to help. Does anyone have an idea or solution to this problem? The nearest Mac dealer is about 80 miles away, so if I can fix this on my own, I would like to try.

I'v just noticed, after installing iStat menus, two different CPU usage measurement graphs. Core 2 duo, so apparently one for each core or chipset, whatever . But the weird thing is, that sometimes, while watching movies, burning dvd etc. (sample "high usage" situation), when the CPU temp. goes around 60 celc. and fan spins at 6200 rpm, one of the "core graphs" shows nothing, like the core is shutting down (screen attached). It's annoying, because the whole system slows down, I can't do anything, and after like 5 mins it gets back to normal (after closing for example the movie). Any solution for this or should I just get used to it?

My Macbook's been overheating and shutting itself down the past two days, usually when on YouTube. Having installed the Fan Control system preference, I can see the fans aren't running at all. My first thought is that they might be broken, but this happened for a little while last year, too, and the fans started working again after a while. Also, it's been miserably hot in my area the past week, and I wonder if that's contributed to it, too (even though the laptop's in an air-conditioned room). Anyway, should I wait and see if the fans begin working again, take it to a repair shop (warranty's expired, so I'm not keen on that), or maybe buy a cooler pad?

So this past week when my mini hasn't stayed in sleep mode, it shuts itself down about a minute later after being in sleep mode. I haven't changed any of my settings in a year and a half, normally it would stay in sleep mode until i come back to it and logged on again. When it does shut down i just cannot power back on i have to unplug the adapter then replug it in for it to start up again. I've searched google and on here for possible ideas. I wouldn't think it to be overheating since I'm not running any applications when i put it in sleep. It might be the power supply since i have to do that process to get it to work again. Let me know what could be causing this or ways to troubleshoot this problem.

Over the last few months I've noticed a trend with my dual 2GHz G5 at home, it often locks up and the fans go full-throttle. It sometimes happens when I'm using it and often when I leave it idling for a while. I've noticed that the CPU A and CPU B temperatures start around 120 degrees F when the machine is first powered up and steadily climbs to around 150. Is that normal? The dual 1.8GHz G5 I have at the office doesn't run hotter than 110 degrees. The fans haven't failed. Is there a coolant link? Is there anything I can do to diagnose this, or do I simply need to call AppleCare?

I currently use an iMac i7 with Windows XP SP3 installed on the Bootcamp partition. I've noticed recently that when I'm on the Windows side for a long period of time the iMac gets quite hot and the fans are raging with a loud roar! Obviously, this does not happen on the Mac OS side. I got quite concerned, so I restarted it in Mac OS to check the iStat. The CPU fan was over 2000rpm and some of the temps just reached over 60 degrees C. So I decided to keep it in Mac for the time being and everything decided to calm down to the 'normal' temperatures. I've searched Mroogle / Google for solutions and it appears people are using smc Fan Control for Windows to increase the fan speeds. I'm not sure if this is the right path to go down where I can override the fan speeds and just put up with the fan noise... but is there another solution? Are there any drivers released to help deal with this issue or is it a windows problem?

So I am about to order a 2010 Mac Pro. I am looking for opinions from users who own or have owned any recent model (last 2 years) Mac Pro in terms of how much heat they throw off and how much open air space they need. The reason I ask is my custom desk at home has one of those wooden "compartments" that a tower or workstation computer can slide into. If I put the Mac Pro in there, it will be exposed on the front, but the top and all sides will be surrounded. I am sure you have all seen the type of desk slot I am talking about. Its a bit like putting your mac pro in a coffin. with only one side open. do you think this will be a major problem and cause overheating? Or result in the Mac Pro shutting down? If so do you have any suggestions because my desk area does not have any open room for the computer stand with all open air around it.

I have just been using my MacBook Pro for 2 hours, 9400M, and 2.8GHZ. The macbook pro seems to be overheating. The temperatures on iStat are:
CPU: 59 Degrees
Enclosure: ~ 40 Degrees
If I use 9600M GT, the temperature goes up to 64 - 68. The left palm rest is VERY HOT for both 9400M and 9600M GT.

Ive been experiencing multiple shut downs, particularly while streaming video from the internet. I think it may be overheating..anyone else have this problem? Running a MBP 2.16CD with snow leopard Also, I'd like to add I just experienced something weird. It was a shutdown, but it was like a shadow melting over the screen, then it said you must restart the computer in a few different languages. What's that about?

I have a new macbook, see stats below.
Up till last week everything was fine, I could run 'Second Life', photoshop, email, a browser, download stuff, play Itunes AND watch a movie all at once without any trouble.
But recently the computer has gone a bit weird.
It started getting very hot, much slower and turning itself off.

When I woke up this morning, I went to use my new Mac Mini. For some reason, it will appear on the monitor for about five seconds, and then nothing will show on the monitor at all. Attempting to restart the Mac Mini only finds it doing the same thing.

When I choose sleep from the Apple menu my Mac Mini with 10.7.4 just shuts off without sleeping. Choosing shut-off however results in an ongoing gray screen with a rotating sign (not the beachball), until I press the on/off switch for about 10 seconds.
Resetting the SMC does not help. Programs like DiskWarrior, Apple hardware test do not find any problems.

I have a MacBook which has recently been shutting down when it feels like :/ this all started a week or two ago (well not the shut downs but other issues that I'll get too), basically the fan I think has been knocked as it is bumping the top or something as the whirring is getting loud and it sounds like every now and again it hits something
Also CPU usage seems to be averaging out at 20% for Safari and 100% for HD Video where as it used to be very small amount for Safari and 30 - 40% for HD.

There's speculation that it's L2 cache is bigger than the 3mb used on the slower mac mini core2duo's.

So I purchased a stereo output to composite red/white cables. I then plugged the HDMI and composites cables into the receiver, but the it reads only the HDMI (which should include audio and video), or composite (yellow, red, white). If you have HDMI plugged it, it doesn't read from the composite, and vise-versa. So how exactly can I fix this? Why doesn't Apple have the HDMI contain audio and video (like most things, PS3, 360, consoles)? This is really odd and I cannot really use it as a home theatre system at the moment. I was hoping that it wasn't my receivers fault (2008 fancy Denon receiver, cost a few grand), but if it was to find some kind of converter that takes HDMI and stereo out, and outputs it as HDMI with audio/video.

I'm considering getting the base Mini and using it as a media hub to replace my AppleTV. I've hacked my AppleTV to run Netflix, Boxee, etc., but playback in Firefox can be slow. The only issue is the lack of Blu-Ray in the mini which would mean getting a Blu-Ray drive and cracking the mini open. Seems like a lot of work but it could replace my Sony Blu-Ray DVD player leaving only my Denon receiver, Cable box and Mac Mini.

I'm looking to replace my parent's cable subscription with a mac mini, the Apple TV seems too outdated and restricted. I plan to couple it with OTA broadcasts, but what else can I do? I see things like Boxee and Plex, what are these and how can I best use them? Are there any better software to use? I planned on using Hulu, getting some massive storage and putting seasond and seasons of shows on there. Note, I don't really need HD content as much, they just don't care. I know I can buy off of itunes, but is there a way to get the news? Like a program that will take a RSS feed of CNN or something? Basically I want Hulu to have news. Can all of this tie into front row? What hardware addons can I purchase? like a tuner or somehting. I'll probably get a used Mac Mini to try it out on first.

I will change my current HD to a new SSD HD (the question is not about replacing physically the HD as it is not supported by Apple..).Â
This is the system disk that contains
- OS X Lion
- apps
- user work/personal dataÂ
There is a big external (SATA, RAID1) HD that receives the Time Machine backups... (and contains user files, pictures, ...).Â
Question:Â
- Is there a way (eg via Time Machine) to save the whole system HD on the external drive
- Then boot (from? Lion comes from Apple Store)
- And recover everything - apps and settings... - from the external drive?Â

Just wondering how many of you guys here have been using the new Mac Mini as a Media Centre mac, and what your general opinions of it are? I'm fairly sure there is HDMI, but is the media playback up to par, and how easy is it to use from the couch?

It's been nearly six years since that fateful day in January 2005, when Steve unveiled the $499 Mac Mini and I promptly bought my first Mac.Flash forward to a few days ago, and the hard drive started making some awful noises hard drives should not be making. It was six years, my first real drive failure. It was time.So I ordered a replacement drive and it arrived today, however I am having some difficulties.

I have set up my Intel Mac Mini in the living room to act as an "Apple TV" but every time I start it up it complains that there is no keyboard and mouse connected. I then have to attach a keyboard and mouse before it will continue booting. Is there a way to disable keyboard and mouse completely? I will either control it remotely or use the remote control for Front Row.
