Best Practice -- Shut down or leave her running?

I have a mid 2010 27-inch iMac which I use every day at home.
When I get up in the morning, I start the iMac to check email, calendar, etc. before leaving for work two hours later, I shut computer down.
When I return home several hours later, I will restart the iMac again, surf the web before dinner, maybe play a game after dinner. Before going to bed, I will shut the iMac down again.
The above process repeats every day. I question is this: which is a better practice? Starting and shutting down the computer during the day, or turning it on once in the morning and shutting it down once in the evening, or not at all?

I would just put to sleep...
you can use a setting that also puts the Hard Drive to sleep so that wont be spinning constantly whilst your iMac is asleep.
It uses next to no power
When you want to start using it again it there, rather than waiting for it to boot with shutdown

I think I finished installing Mountain Lion, and am at the "log in" page with my name and the Lion icon, but I cannot do any of the functions on screen. That is, I cannot log in, sleep, restart, or shut down. I am running it on an Early 2009 Macbook Pro

That is, I cannot log in, sleep, restart, or shut down. I am running it on an Early 2009 Macbook Pro, which is said to have the capabilities of running Mountain Lion.

As the last post suggests, call Apple and order a replacement original disc for about $17. They will ask you the model and serial numbers.
Your retail version of Snow Leopard OS 10.6.3 will not work on that Mac as it requires a minimum of OS X 10.6.7 to boot and operate.
Another alternative is to again borrow another Mac to install your retail Snow Leopard into an external HD or partition, upgrade it to 10.6.8 and then clone it back to a partition on your MBP.

Macbook Air 11" shuts down after few minutes running

My Macbook Air 11" from mid 2012 shuts down after few minutes running, it is a laptop with very light use. The first time this happen was trying to upgrade to OS X Mavericks, after this I read it was maybe an overheating and definitely the case was hot, after this I placed the computer right in front the AC to finish the upgrade, finally I successfully upgrade the OS but the problem continue. I bring my Mac to service and now they said it is a Video Card problem, it doesn't make to much sense for me. Can somebody let me know if this could be a Video Card problem?

At what point is the shutdown occuring? As soon as you launch the install app?
If so, I would trash the install app file, and re-download it.
First, you might try running a Repair Permissions & a Verify Disk from the Recovery Partition. It is always a good idea to do this before any major software update/upgrade.

Shuts down after ~10 mins running on battery

For a year, my MacBook Pro ran fine. At the beginning of the previous school year (around September of '07), my notebook began to shut off before the battery was fully drained. Gradually it began to shut off sooner and sooner, until it finally shuts down not even ten minutes after unplugging it. The battery is only at around 90% when it kicks the bucket. When I try to turn it back on, the computer makes a noise as if it is going to turn on, but quickly drops dead again. Plugging it back into the power remedies this and runs normally, but what's the point in having a notebook if I can't work on it unplugged...?
Anyways, while at college I took my computer to the IT desk. Replacing the battery once didn't help, so we tried another battery... we must have done this four times with no avail. They decided to send my Macbook Pro to Apple and after a few weeks I got it back. For a few days it worked fine while running on the battery, but then it started malfunctioning again until I got back to square one. I didn't take it back to IT because I desperately needed my computer to work on assignments.

Please help, this problem is very annoying.

There are several things you can do I understand.
1) Check the battery condition using a program like the widget iStatPro (free). If the battery health is less than 80% then Apple have a free replacement program for this.
2) Switch the machine off and disconnect the power supply. Remove the battery and leave out for several minutes - to allow complete discharge of all electronic components, I think. Then re-instal the battery, etc and restart. I'm not 100% clear on all steps in this procedure but it provides a reset which sometimes resolves problems at least temporarily.
3) Disconnect all peripherals and see how it works. One of these might be calling for more power than it should.

Windows Explorer shuts down when trying to run Quicktimes

We are using Quicktime 6 Player on PCs running Windows 2000 Professional. Whenever you try to run a Quicktime movie from the Explorer browser, it shuts down along with Quicktime!!!
In addition, we cannot copy or move Quicktimes from one folder or drive to another without both software packages shutting down. The Quicktime movies are varied and are themselves not bad files. The only way I have found that allows me to run, copy or move Quicktimes is to work within Start/Run/Browse and doing a bunch or Right Clicking!!!
We are all up to date in regards to Windows Updates, so I am at a total loss as figuring out what the fix is. Any ideas? gsarahs

Naveen,
The reports where developed in the current version.
There isn't any other version installed on the machine.
I only have Crystal Reports Developer XI installed on 1 machine in the office. The reports are loaded in the Business Objects Management Console and available for other office staff to run from the Business Objects Viewer. The reports run OK from the viewer.
I have tried un-installing Crystal Reports Developer XI and re-installing it already - the problem still occurred.
There are a number of faulty reports, some query 1 database others only 1 database, some have SQL tables others do not, most of them have subreports, formula fields, parameter fields, and group name fields, 1 also has a running total field.
Most of the reports I have created are similar but have different selections.
Thanks for your help, hope we can find a solution.
Ann.

Late 2008 Macbook Pro shutting down at 94% while running on the battery

So I called Apple about this issue last week, since I tried calibrating my battery to improve it's health. And when my battery life got down to 94% or lower... my laptop just shut down. For no reason. When I called Apple, the guy I talked to before said it sounded like my battery was defective. He hooked me up to a tech guy, and when I told him what was up, he said that all the numbers on my battery sounded normal, and that he thinks that my logic board is failing. I'm not entirely sure what is up. These are the numbers I am getting now, one from iStat Pro, and the other from System Profiler:

I had my laptop plugged in all day, but I unplugged it for like, 2 seconds because the LED light on my 85w Magsafe Adaptor was out again... just from bumping it. It was at 82% battery health yesterday, and was fully charged. The battery, as well as the adaptor and laptop are a little over 2 years old. My battery health has been declining since January... it was at 86% health at the end of January, near the beginning of February... then a few weeks into February, it went down to 84%, then 81%... up to 82%, and now down to 79% health. What on earth is going on? Do I need to get a new battery along with a logic board replacement?

Software update to 10.6.8 fully?
Reinstall 10.6 only then Software update fully?
You can do that by backing up data off the machine and disconnecting, then c boot off the 10.6 disk, just reinstall OS X over the more recent copy, then reboot holding shift key down (precaution) then Software update fully to 10.6.8.
then you'll have to check all third party software to make sure it's running, some install kext (kernel extension) files into OS X which get booted out by the overwrite install method, so install those again from fresh sources.
If that doesnt' fix your issue then it's a firmware or hardware issue..
run a hardware test

For the "D" you need a internet connection previously (don't move if on wifi) and hold that D down for quite some time.

System shut down during F110 payment run

During the F110 payment run, the PRD system shut down. There were 259 items in the proposal and according to the status 42 posting orders were generated and completed. What is the process to handle this problem? Can the payment run be re-started?
It appears that clearing documents were created for some open items before the system shut down but no checks are showing in the check register. Has this happened to anyone before and what steps should be taken to resolve this?

Is it a matter of...
1. deleting the output of the payment run,
2. deleting the proposal
3. canceling the the payment check by check using FCH8 if any occurred
4. reseting and reversing the clearing documents created using FBRA before the system shut down
5. start a new payment run

Best practices for checked exceptions in Runnable.run

Runnable.run cannot be modified to pass a checked exception to its parent, so it must deal with any checked exceptions that occur. Simply logging the error is inadequate, and I am wondering if there are any "best practices" on how to deal with this situation.
Let me give a real-world example of what I'm talking about.
When writing I/O code for a single-threaded app, I'll break the logic into methods, and declare these methods as throwing an IOException. Basically, I'll ignore all exceptions and simply pass them up the stack, knowing that Java's checked exception facility will force the caller to deal with error conditions.
Some time later, I might try to improve performance by making the I/O code multithreaded. But now things get tricky because I can no longer ignore exceptions. When I refactor the code into a Runnable, it cannot simply toss IOExceptions to some future unnamed caller. It must now catch and handle the IOException. Of course, dealing with the problem by simply catching and logging the exception is bad, because the code that spawned the I/O thread won't know that anything went wrong. Instead, the I/O thread must somehow notify its parent that the exception occurred. But just how to do this is not straightforward.
Any thoughts? Thanks.

My suggestion: don't use Threads and Runnables like this.
Instead implement Callable which can throw any Exception.
Then use an ExecutorService to run that Callable.
This will return a Future object which can throw an ExecutionException on get(), which you can then handle.
This has the additional advantage that you can easily switch from a single-threaded serialized execution to a multi-threaded one by switching ExecutorService implementations (or even by tweaking the parameters of the ExecutorService implementation).

Firefox won't shut down. I am running 3.6.8 on a Mac. I haven't had this problem until recently.

Firefox won't shut down properly. I am running 3.6.8 on a Mac and usually I have to force quit to get it to shut down. This has only begun recently. If I knew how to roll back to a previous version I would and save you the trouble, but alas, I do not.

I'm having this same problem. I am going uninstall Firefox and install Google Chrome. This is ridiculous that there is NO solution Mozilla can provide us! I can't shutdown my Mac because Firefox won't shutdown. I got a script error message, tried to STOP or CONTINUE To no avail.

MBP shuts down without warning when running on battery

I've had my MBP for over a year but rarely used it on battery power. Lately I have been doing so and find that as the battery gets low (I'm not sure how low) the MBP just shuts itself down without warning. No "low battery" message, nothing—just shut down and total loss of unsaved data. I checked the support page about the battery recall, and it doesn't describe this problem, so I am not eligible.
I installed Leopard (fresh format and install) just before this started happening, but I can't be sure it has anything to do with it since I didn't use to use the MBP on battery before.
Is there anything that can be done about this?
TIA

Good morning,
You may wish to perform a reset of your SMC and see if that helps. You can find the instructions on how to perform this in [Apple Support Document 303319 : Resetting MacBook and MacBook Pro System Management Controller (SMC)|http://docs.info.apple.com/article.html?artnum=303319|Resetting MacBook and MacBook Pro System Management Controller (SMC)].
Hope this helps! 

Macbook Pro shuts down intermittently and kernel_task running at 300% constantly

I've bought a refurbished 13" Macbook Pro (early 2011, Mac OS X Lion 10.7.3) last month and it was working fine all along until yesterday, when the MBP decides to shut itself down while I was surfing the web through Safari and that's why my problem begins.
What my MBP had shown over the past two days.
1. Intermittent shutdown, even when the MBP is left there by itself, with or without magsafe adapter.
2. Instantaneous shutdown whenever I plug in the magsafe adapter.
3. Activity Monitor shows that kernel_task is running at >300% of CPU usage when booted in normal mode, fan speed is only 2000+rpm.
4. In safe mode, kernel_task down to <2% CPU usage, MBP will still have intermittent shutdown.
5. Uninstalled all third-party applications, problems persist.
6. Already performed PRAM reset and SMC reset, situation unchanged.
Looking at all this, I definitely should visit an Apple Authorised Service Provider near my place to get this sorted out. However, if anyone has an inkling of what's going on, I don't mind hearing your comments.
Thanks!

Pavilion TX2000: Shuts down when plugged in, runs perfect on batter. Any help?

It's been a pain, but I basically revived a dead Pavilion TX2110us (replaced the motherboard, installed windows 7, recovered missing drivers, ect.) and it's been running great when powered by the battery. Big downside to that is the battery life isn't great. Typically about maybe 2 hours on battery saver settings. However when I have it plugged in to the power source, I'll get anywhere from 5 to 30 minutes before it just powers off on its own. I have tried to configure the power settings and it has seemed to help somewhat, but the problem for the most part still exists. Does anyone know how I can fix this permanently? I would really like to be able to get the maximum performance out of it while plugged in without the worry of everything powering down every so often.

HI Aframie,
Please provide your complete product number only. Instructions on finding your product number can be found here.
I also need the your operating system and whether it is 32 bit or 64 bit. Is this the factory installed operating system or have you upgraded your operating system?
