HT1199 My Mac shuts down on its own and it is slow

Hello,
My Mac is slow. It sleeps and in order to start it again, i have to force shut it using the power button and restart it.

I've requested your thread be moved.
https://discussions.apple.com/docs/DOC-3036 is a common reason why you might have slowness, if you installed MacKeeper. Any System utility that touches System Cache can slow you down.
If you are backed up, we can explore other reasons:

Is it possible that you or someone who knows your iCloud sign on went into the Find My iPhone app and erased your device via iCloud? Because that is what that message is saying.
Have you tried to sign on with your Apple ID and password?
Was it online prior to this incident happening?

My iPad shut down on its own and now will not turn back on ?

My iPad turned it self off earlier today it had 13% battery the last I remember looking, so I thought it ran down more than I thought. So I put it on charge and it still wouldn't turn back on, so I left it for a couple of hours, but when I came back it turned on long enough for me to put in my password before it turned off again, it has charged as it now had 58% battery. However I am now trying to turn it back on and it won't do anything more than show the apple logo?!?!
Help!!!!

First try a Reset ( No Data will be Lost )
Press and hold the Sleep/Wake button and the Home button at the same time for at least Ten seconds... (But can take Longer)... until the Apple logo appears. Release the Buttons
If no joy... Try a Restore...
1: Connect the device to Your computer and open iTunes.
2: If the device appears in iTunes, select and click Restore on the Summary pane.

Beer might have gone into MacBook Pro from the back, shut down on its own 5 minutes later. what to do?

I'm currently working in Myanmar and no chance to going into a Mac service provider or store. I was using my Macbook Pro (mid 2010) when beer was spilled onto the table. I lifted the computer instantly and as i did not see liquid on the machine and also it had a protective cover i was sure no liquid got in. I removed the cover and it was dry but then 5 minutes later it shut down on its own and it would not turn back on or charge. I left it for an hour or so and then it turned back on and was charging but then since i thought that may be it was because some liquid got in, I turned it off again immediately and disconnected from power source.
what is the best way to proceed knowing i won't be able to bring it in to a technician anytime soon?

without on hand diagnostics, nobody can tell you the correct answer on that. No.
5 minutes later it shut down on its own and it would not turn back on or charge.
bad news
Liquid spills, why your MacBook chassis is a one-way valve for spills
After a substantial spill many people will turn their notebook upside down and shake it, not only does this not work, but it spreads liquid havoc throughout your machine and makes things often as bad as possible.
The keyboard itself acts like a one way valve in the case of a substantial liquid spill. While liquid pours into the bottom chassis easy, it does not come out easily at all, and in the case of any spill, most of it will not come out by turning it upside down. Disconnect all power and contact Apple for diagnostics and repair.
Do not attempt to, after a spill, ‘dry out your MacBook’ and test it
After a spill most people invariably try to “dry out” their notebook by various methods, including hair dryers and otherwise. This both does not work, and after a substantial spill of any magnitude, even if the liquid was water, residue is left behind.
There are additionally many very tight places inside your notebook where liquids will linger for a very long time, and cause corrosion or worse.
Immediately unplug your notebook and contact Apple for in shop diagnostics and parts replacement.
In the case of very minor spills people will “dry out” their notebook and feel success that their notebook is working ok, however invariably in nearly all instances after 4-14 days an error / fault pops up and is usually followed by more.
In case of a spill, damage estimates are impossible,.....anything can be fixed, without question.......the question is cost.
contact Apple for in shop diagnostics and cost estimation ....possible parts replacement.

My iPad air keeps shutting down on its own!

My iPad air keeps shutting down on its own, and this is the second IPad Air doing this. I really don't want to go trade it in for another. Does anyone have the same issue and is there a way to fix it? And yes I've done the manual reset and computer reset.

Memory Size & The Impact of 64-bit Applications
The iPad Air, like the iPhone 5s, ships with 1GB of LPDDR3 memory. Apple frowns upon dissection of review samples but I think it’s a safe bet that we’re not talking about a PoP (Package-on-Package) configuration but rather discrete, external DRAM here. It’s also probably a safe bet that even the iPad mini with Retina Display will ship with 1GB of memory as well.
Something I didn’t have time to address in my iPhone 5s review was the impact of 64-bit applications on memory usage. I actually ran some tests after the 5s review hit but never got the chance to share the data, so I figured now is as good a time as any to do just that.
Unlike traditional desktop OSes, iOS doesn’t support paging to disk (or in this case, NAND). Application data can either reside in memory or the associated process is terminated and has to be reloaded the next time you request it. It’s a decision likely made to both maintain user experience and limit the number of program/erase cycles on the internal NAND.
The good news is that iOS was architected to run on as little hardware as possible and as a result tends to be quite memory efficient. There are also power implications of going to larger memories. The combination of these two things has kept Apple on the conservative side of increasing memory capacity on many iDevices.
The move to a 64-bit platform however does complicate things a bit. Moving to a larger memory address space increases the size of pointers, which in turn can increase the footprint of 64-bit applications compared to their 32-bit counterparts. So although there’s clearly a performance uplift from app developers recompiling in 64-bit mode (more registers, access to new instructions), there’s also an associated memory footprint penalty. Since the iPad Air and iPhone 5s don’t feature a corresponding increase in memory capacity, I wondered if this might be a problem going forward.
To find out I monitored total platform memory usage in a couple of scenarios. Before measuring I always manually quit all open apps and performed a hard reset on the device. Note that the data below is reporting both clean and dirty memory, so it’s possible that some of the memory space could be recovered in the event that another process needed it. I hoped to minimize the impact by always working on a cleanly reset platform and only testing one app at a time.
I looked at memory usage under the following scenarios:
1) A clean boot with no additional apps open
2) Running Mobile Safari with 4 tabs open (two AnandTech.com tabs, two Apple.com tabs, all showing the same content)
3) Infinity Blade 3 (64-bit enabled) sitting at the very first scene once you start the game
4) iOS Maps in hybrid view with 3D mode enabled, with a WiFi assisted GPS lock on my physical location
5) Google Maps in the same view, under the same conditions. I threw in this one to have a 32-bit app reference point.
In general you’re looking at a 20 - 30% increase in memory footprint when dealing with an all 64-bit environment. At worst, the device’s total memory usage never exceeded 60% of what ships with the platform but these are admittedly fairly light use cases. With more apps open, including some doing work in the background, I do see relatively aggressive eviction of apps from memory. The most visible case is when Safari tabs have to be reloaded upon switching to them. Applications being evicted from memory don’t tend to be a huge problem since the A7 can reload them quickly.
The tricky part is you don’t really need all that much more memory. Unfortunately as with any dual-channel memory architecture, you’re fairly limited in how you can increase memory capacity and still get peak performance. Apple’s only move here would be to go to 2GB, which understandably comes with both power and financial costs. The former is a bigger concern for the iPhone 5s, but on the iPad Air I would’ve expected a transition sooner rather than later.

Mac Pro shut down on its own, then on boot up it beeped steadily for 2 min?

I put my 2009 Mac Pro to sleep then the next day I find it completely shut down! I boot it up and then I hear a steady beep (every second) for about 2 minutes. After 2 minutes the beeping went away.
Any idea what caused Mac Pro to shut down on its own? And what does the steady beeping mean? The beeping is coming from inside the Mac Pro's speakers, not from my BOSE 5 computer speakers.
I don't think there was a power outage as the UPS is fully charged, and I asked a neighbor across the street.

I wasn't clear in my description, it's a steady continuous beep, it's a rhythmic beep -- it'll do this for 200 beeps or about 2-4 minutes.

Mac mini shut down on its own, will not restart, grey screen, spinning wheel. Unplugged everything, will still not restart. Did safe boot, will not restart after safe boot, only grey screen with spinning wheel.

Mac mini shut down on its own. Could not restart, chime, grey screen and spinning wheel. Unplugged everything but monitor, still only chime, grey screen and spinning wheel. Started in safe boot, shut Down, will not restart.
This happened a couple of months ago, unplugged everything and it restarted, now that won't work.

Hi BDAqua,
I just did the repair as you suggested. T ran the disc repair, and twice it cam back, the volume macintosh seems ti be okay, I also ran the verify and permissions repair, both came back okay.
I was actually hoping that they would find something, so they could repair. I shut the computer down, and restated with out holding a key, and I started up great. I'm baffled. I have moved 20 GB to an external hard drive, as I only had 10% open space.
I have Tech Tool 6, would you recommend to run a repair check on that, or just leave well enough alone.
I agree with you on the new Mac's, I have problems with no disc for back up, until they realize their mistake I will stay with Snow a Leopard. This is the first problem I have experienced, so I can't complain. Their last programs are not as perfected as under Steve, prior to his handling over the reins, hope this is not going to be the future we can expect from Apple.
I will wait to here back as to your suggestion regarding the Tech Tool check
Thanks for all your help.
Gratefully,
Cheri

Macbook Pro 2010 upgraded from Mavericks to Yosemite keeps shutting down on its own

I upgraded to OS X Yosemite about a month ago, I have a macbook pro 2010, and in the last two weeks it started shutting down on its own. At first when i'd wake it, the fan would come on loudly and then it would shut down. In the last couple of days, I would make sure all programs were shut when it wasn't in use and then put it to sleep but every time i'd return it would be shut down and need a hard restart. If i just pressed the on button lightly it wouldn't start. And when i turn it on the fan comes on immediately. I'm a publisher so I'm working in indesign and illustrator a lot but I keep a constant look out for my memory and this isn't the problem. I'm working to a deadline here and can't afford to lose my computer for 3 days in the mac store (I live in Barbados) to get it fixed. Any advise?
Thanks

MacBook Pro won't boot and shut down on its own.

Hi, I am running a Macbook Pro. My problem is that the OS froze during use, and I could not move the cursor. As which point I force shut down by holding the powerswitch. From that point onwards I could not get the machine to boot, it keep getting stuck at the grey screen with Apple icon. After loading at the grey screen for 15-20 mins it shuts down on its own.
I've tried to reset SMC (shift-control-option + power button) and PRAM (Command-Option-P-R) but it dint work. Please help. Thanks.

It appears your problem occured after you upgraded to 10.8.2, but if you did it right after the SSD and RAM switch then it's hard to tell exactly what is causing the issue.
I advise returning back to factory, hold command option r boot and wipe everything and reinstall 10.8
..Step by Step to fix your Mac
If the problem continues, then make a warranty/AppleCare call, hopefully you didn't strip the screw heads or leave any other tell tale damage inside.
If your fine on 10.8.2 for some time, then switch the RAM and do a hardware test extended or Rember or Memtest to make sure the new RAM is not the issue.
If that's fine then Carbon Copy Cloner to the external SSD and hold option key down to boot from it and test that.
Then do the internal SSD switch and test that.
Take your time, Mac's are so finicky and you can't just slap this or that and expect it all to immediatly work like it should.

Is it normal for an ipad to shut down on its own?

the problem is my ipad suddenly shut down on its own having 70% of the battery charged and it would´t turn on again. i went for help to the mac service on my city, im from mexico, and the guy there just turned it on using the home button and the power button, and said it was normal, it happend to all ipads, iphones and ipods, i did not consider it normal, i own 2 ipads, 1 ipod touch, 1 iphone 3gs, 1 iphone 4, and i know other iphone users that have never had this problem, but the guy just said its normal. so i want to know of he told me the truth.

It happens occasionally- it's happened to me once (so far) and if you search these forums you will probably find a couple of threads a day from people who have had the same thing.

Is the little LED on your adapter's MagSafe plug glowing when it's connected? What color?
It sounds as though your battery is drained and the adapter isn't charging it. Try resetting the SMC:
http://support.apple.com/kb/HT3964
That may start the battery charging again.

Computer shuts down on its own even with full battery life.

I purchased a new battery for my 13 inch aluminum MacBook. Installation was fine and dandy but even with a full charge, if I don't have my power adapter connected, the computer will shut down on its own without warning. Is there a fix for this?

Have you reset the SMC?
