  You really should get in the habit of shutting down for the night. Cures many ills. Nothing really stands out here to me.

  really biff? I've heard things on both sides (shutting down at night and not doing it) I was told that the computer does *stuff* overnight and should be left on..you think I should totally shut down each night? Is that good for iMac?
  (thanks for answering this..I know you have a lot on your plate..didn't want to bother you directly)

  I may add if you say I should shut down each night I shall

  Once a week let it run overnight- alternatively, run cocktail or onyx or any one of a host of applications. The cron jobs don't need to run every day. The issue is less a shutdown overnight, as it is a frequent reboot.
  Regardless of personal experience, Apple suggestions or whatnot, reboot daily. You won't be sorry.

  I will!! Starting tonight..just thought poking the button to turn it on each morn was a harmful thing..I am RE-THINKING even as we speak..

  You can always use the energy saver control panel to schedule shut down and startup times.

  Question..does doing that (setting up to shut down by itself)mess with the *screen lock* set up at all?

  meant to say, what you describe is slightly odd but then every so often machines will get corrupt preferences, etc, and do random shit..
  I'd be tempted to do some good old fashion house cleaning before worrying to much..
  run cocktail, as biff says, delete all the apple prefs you don't mind resetting, etc..

  my imac has been known to shutdown all by itself, not very gracefully, maybe 10 minutes into use in the morning. one minute fine, next minute *blink*.
  it's not done so for quite some time now, but it was thought that it may have been a dodgy cap or something.. who knows.

  Eek. I used to shutdown religiously, now not so much. I think i'll go back.

  veedot, they're right that your iMac shouldn't do that...
  i've a niggle that your graphics card is trying to drop a hint.
  just to make yourself feel better, why not run the Hardware check that's part of your OS X install disk? (put in disk, hold down D key while booting.)
  me, i'd also stop using the screensaver. imo they're nice, but they do 'exercise the pixels' when there's no need, and after having a couple of displays die a premature death, i've quit using them.
  i hope it's all good, and i'm overthinking this..

  I agree with you about screensavers,mick, and don't use 'em..
  I've run Techtools Hard drive tests and another,deeper diagnostic program and the hardrive is coming up ok..thanks for the advice.I set 'er up to shut down and turn on again..I'm monitoring to see what happens..
  welcome back..:happy:

  Random iMac shutdowns continue
  Users continue to report an issue in which various iMac models randomly shut down during routine operation. As described by one user: '..it randomly has shut down on me at least 12 times since I turned it on. I can restart it and it'll stay on for a long time. But then, randomly it'll shut itself off again.'
  This problem has been reported by several other users, but one user has a unique situation in which his computer restarts at the slightest vibration, indicating a hardware fault of sorts in the power system, potentially due to faulty wiring.
  It is possible that a batch or two of iMacs have faulty wiring that have caused, or at least contributed to, these random shutdowns and restarts. In the case of the iMac that's sensitive to touch, it's very possible a loose connection in the power system causes the thing to disconnect and shut down. Additionally, one user reports that setting the computer to restart after a power failure causes the system to restart instead of shutting down, adding further evidence that this is a hardware problem.
  Some users report that getting their iMacs' power supplies replaced by Apple resolves the issue.
  As previously reported, some users have also had success with the following fixes:
  Reset SMC
  Turn the computer off
  Unplug all cables from the computer, including the power cable and any external device cables.
  Wait 30 seconds.
  Plug the computer back in and connect the keyboard/mouse, then turn it back on.
  Re-seat RAM The problem could also be improperly seated RAM modules. Try removing the RAM modules then firmly seating them back in place.
  As described in Apple Knowledge Base document #303083:
  'If the computer detects no SDRAM (Synchronous Dynamic Random Access Memory, also referred to as RAM) or the RAM installed does not meet the appropriate specifications, the screen will remain black but the power LED on the front of the computer will blink once per second to signal the error. This error condition may be due to physically damaged RAM, installing the incorrect type of RAM, or not having RAM installed.'
  If the problem continues after performing the aforementioned fixes, the next step is to take the computer in and get the power supply inspect and serviced.

/Mac Cleaner /iMac OverHeating: How to Fix It

I have a Mac device and I use it for pretty much everything. I use it for work and I also use it for recreational purposes. Recently, I have noticed that my Mac is overheating. Sometimes I touch my device and it literally feels like I'm in hell. Also, my device shuts down by itself all the time. What can I do about this overheating issue?

Part 1. Introduction to iMac OverHeating

Is your Mac device heating up too much that it's too hot to touch it? Or is the fan too noisy that you feel like it's overworked? Well, if you're experiencing these you're actually noticing the results of your Mac device' overheating. This problem is common among a lot of Mac users.

Overheating is not just limited to these two signs. Usually, a Mac that overheats will crash or shut down by itself. This issue is not a light one and you wouldn't I want to ignore it. Overheating can actually slow down the performance of your Mac and it can damage your device' internal components over time.

You have to remember though that it is actually normal for Mac devices (or any other device) to heat up when it is working heavily and using up many resources.

However, crashing and shutting down because of heat is not a normal scenario. Consistent overheating of your Mac device during times of regular use is probably a sign that you have an issue at hand.

In this guide, we're going to teach you tweaks to help you with overheating.

Part 2. How to Fix iMac OverHeating?

Imac Shutdown By Itself

Obviously, the results of your Mac device' overheating could be so annoying. Then we'll show you methods to help you fix iMac overheating:

1. Prevent vents are blocked and clean up the dust from your Mac device.
2. Monitoring the spotlight indexing.
3. Checking the device' Fan.
4. Shutting down runaway applications.
5. Not using Fan Control applications.

Method 1 - Easy Measures

Mac Shutdown By Itself

We will go with the easiest solutions first. You have to use your Mac device and place them on flat surfaces. This allows your device to dissipate heat easily.

Why Does My Mac Shut Down By Itself

Aside from that, you have to ensure that vents are not covered. If you want to use your device on your lap or the bed, minimize the way vents are blocked. Your device might be suffocating because the vents are blocked. Next, avoid using your Mac under the sun. Direct sunlight is very hot and of course, it will lead to overheating.

Transcribe a specific scene in the drama. Finally, you have to clean up the dust from your Mac device. You can use a vacuum cleaner to remove dust built up on your Mac. This dust prevents your Mac from keeping itself cool.

Method 2 - Monitoring The Spotlight Indexing

If you think you are not using your Mac device to perform a heavy task and it still heats up, you have to check out the top right corner of your desktop and look at the magnifying glass icon. If a pulsating dot appears within the magnifying glass it actually shows that Spotlight Indexing of data is happening.

This process is actually automatic and takes a few hours to finish. It also uses up A LOT of Mac's resources. What you can do is to plug your device to the power.

Then, place it on a flat surface where vents are not blocked. After which, try to do other things while indexing occurs. Just get back to your device once indexing is finished.

Method 3 - Checking The Device' Fan

Is the fan making a strange noise? Well, there could actually be a physical issue with the fan and this could lead to the device' overheating.

Here are the steps you can follow in order to run a diagnosis on your Mac device:

Step 1 - Connect your device to the power cable. After which, shut your Mac down.

Step 2 - Press down the Power button while holding the D key down. Do this before the actual startup screen appears.

Step 3 - Follow the specific instructions that will appear on the screen. If you are utilizing an older Mac device, you should select the Basic Test.

This diagnosis process will check out the issues you might have with your fans.

Method 4 - Shutting Down Runaway Applications

If your Mac is constantly overheating, try to use Activity Monitor all the time. You can find it in Applications > Utilities. The Activity Monitor allows you to check out which processes are responsible for overheating.

You just have to click the CPU column to allow you to sort processes from the most active to the least active. If you see an application that is not working on a heavy, important task (as of the moment) but uses nearly 90% of the CPU, then it might be a non-responsive app that is eating up too much of your device' resources. Or other files as well. For you to find and end up the purgeable space on Mac, you can turn to this link to learn more details: https://www.imymac.com/mac-cleaner/mac-purgeable.html.

You simply have to close these applications. However, if these apps continuously cause you problems, you have to remove them completely. How do you do this? You need to use a tool called PowerMyMac's Uninstaller to completely wipe out the app.

Here's how to use the tool:

Step 1 - Download iMyMac PowerMyMac and install it. Then launch it on your device.

Step 2 - Choose the module Uninstaller on the left-hand side of the interface.

Step 3 - Click Scan. Wait for the program to scan the entire device.

Step 4 - The results will show a list of applications on your device. Select the application you want to remove.

Step 5 - Click Clean to uninstall the app.

Method 5 - Not Using Fan Control Applications

Guides will tell you to use third-party fan control apps. This tool enables your fans to run fast. This can actually help address Mac's temperature heating up for the short-run.

However, it fails to address the actual issue that causes the overheating of your Mac device. It's also pushing your fans to exert more effort which leads to its wear and tear.

Imac Shutdown By Itself How To

Plus, using a third-party tool to control your Mac's physical properties can void its warranty. When you discover that a hardware issue is present, you would probably shell a lot of money cause your warranty is already void.

Part 3. Conclusion

Your Mac can overheat because of a lot of issues. You can actually fix these by taking practical measures, monitoring spotlight indexing, checking your Mac's fans, not using fan control applications, and closing runaway apps.

Aside from these, you can also remove unwanted applications that might be hogging too much of your resources. For this, you can use iMyMac PowerMyMac's Uninstaller. This tool will help you wipe out unwanted applications without causing issues on your device.
