SHOULD MACINTOSH COMPUTERS BE SHUT DOWN EVERY NIGHT?

Should I shut down my iMac every night?

My Mac's sleep 24-7 and I only shut them down when I'm gone for more than a day or two.
Mac's can easily go beyond 45 days without being shutdown or restarted.

    my imac (intel core i5, OS 10.10.1) shuts down every night and will not "wake up" next morning -- it never used to do that -- if I hold down the start button more than twice for many seconds, then it will finally boot up and works fine all day – I’ve tried shutting it down and unplugging it, and that does not work -- I’ve run disk utilities checked permissions, and run anti-virus and get no adverse results – I cannot figure out what is different that causes this problem

    From previous experience 3 indicates a shutdown initiated by the SMC (System Management Controller) — hardware responsible for many low-level functions including power, sleep, lights, and fan activity.
    Try resetting it:
    Power or other problems related to unexpected system sleep, shutdown, lights or fans call for an SMC reset. Read all the steps.
    Before Resetting the SMC
    Try each of the following steps in this order before you reset the SMC. Test the issue after completing each troubleshooting step to determine if the issue still occurs.
    Press Command + Option + Escape to force quit any application that is not responding.
    Put your Mac to sleep by choosing the Apple () menu from the upper-left menu bar and then choosing Sleep. Wake the computer after it has gone to sleep.
    Restart your Mac by choosing the Apple () menu from the upper-left menu bar and then choosing Restart.
    Shut down your Mac by choosing the Apple () menu from the upper-left menu bar and then choosing Shut Down.
    Resetting the SMC for Mac Pro, Intel-based iMac, Intel-based Mac mini, or Intel-based Xserve
    Shut down the computer.
    Unplug the computer's power cord.
    Wait fifteen seconds.

  • My mail program takes a long time to open and the whole system takes almost 2 minutes to shut down at night What should I do?

    Hi, Recently my system has been slow to boot up in the morning & slower still to shut down at night.
    Also my mail program is slow to open. I do have emails archived but my trash is always deleted & I'm trying to keep my "sent" folder not too full
    Occasionally any programs I'm working in (Photoshop, InDesign, Illustrator, etc) takes time to process whatever task I'm doing. (This happens maybe once or twice a week, not often)
    thanks

  • Sleep or shut down at night?

    Hi, it just occurred to me that in summer with frequent lightning storms especially during the night, might it be a good idea to shut the computer down and disconnect the power adapter at night?
    I tend to use the computer plugged in during the day, with short periods of battery use, and then at night I leave it plugged in and just close the lid. Even with old PC's I did this without a problem, but with my new MBP I don't want to take any chances!
    Thanks,
    Karen

    Thanks.. re. shutting down at night, I thought there was an issue of wear and tear from starting up so often.. otherwise it would certainly be simpler to shut down and not worry about nighttime power surges.
    I don't worry about wear and tear, because although technically it might be better to run your computer at full power 24/7 to avoid premature wear from thermal and power cycling, realistically nearly every Mac user either sleeps or shuts down their laptop at least once a day whether that's at night or merely to transport it (since it is a laptop after all) and therefore powering off is the norm, and it is not causing mass early laptop deaths.
    We are also weighing leaving the computer plugged in versus the potential damage from a lightning strike, and we're saying the potential damage from sleeping or shutting down at night is assumed to be less severe than that of a direct lightning hit.
    Re. sleeping the computer all night and draining the battery, I do that once a month to calibrate the battery, but isn't it recommended to not drain deeply too often?
    You are right that is is recommended to not do deep discharges too often. But an overnight sleep does not drain the battery that far, maybe a few percent. What I didn't mention is that if your battery is new and fully charged, it will probably last around a week in sleep mode. One night off the charger isn't going to drain the battery unless, as I mentioned, it's an old battery with a fraction of its original capacity.

  • How do I uninstall iBooks on my iPad?  After the update the app shuts down every 30 pages or so. Super frustrating.

    How can I uninstall iBooks on my iPad?  After I upgraded the operating system, the app shuts down every 30 pages or so. It is super frustrating. Never had a problem before.

    With iOS 8 it's now a built-in app, it can't be deleted/redownloaded.
    You've tried closing the app (and other apps) via the iPad's taskbar and done a soft-reset to see if that improves things ?
    Closing an app :  iOS: Force an app to close
    Soft-reset : press and hold both the sleep and home buttons for about 10 to 15 seconds (ignore the red slider), after which the Apple logo should appear - you won't lose any content, it's the iPad equivalent of a reboot.

  • 1020 shuts down at night - requires soft reset

    I am on my second 1020 .  First one had a faulty audio jack.
    This one shuts down at night inexplicably.  I wake up to check email in the morning and the screen is black.  No buttons do anything.  My only hope is to soft reset.  I charge overnight using the charger that shipped with it.  Twice it has happened while charging.  Once it happened while not charging.  I've had one other likely unrelated crash - while on a call I hit the camera button by accident and the screen turned a rainbow of colored pixels.  Had to soft reset.
    I emailed Nokia support - nothing.  I'm assuming I should take this 1020 back as well but I can't keep dealing with faulty phones.  I tried removing a bunch of apps from my start screen and didn't seem to make a difference.  All I have is basic stuff - phone, email accounts, facebook, store, xbox music.
    any suggestions or best to assume some faulty hardware, perhaps memory?  It has had a shut down 4 of the 5 nights I've owned it.

    No not exactly - that particular phone did better by ensuring I killed all app background tasks (check settings periodically as apps turn them back up after updates and running for 1st time), and using the back button to back out of apps instead of hitting the home button.
    However - that phone got stuck in a funky state where it thought the phone had a headset plugged in even when it didn't.  So it was returned, and I'm not on my third 1020.  The reboots on this one are worse then the prior 2 in frequency - happens once or twice a day at least.  The only benfit of this one is that it doesn't lock up like the other one did.  It will reboot and come back gracefully. Background tasks and backing out of apps hasn't helped this behavior.
    What is baffling is how all three of my phones despite being set up the same have had very different  behaviors in terms of random restarts.

  • Itunes shuts down every time i try to sync with my iPhone

    itunes shuts down every time i try to sync with my iPhone

    Well reading some other discussions i have found to try deauthirizing and reauthorizing, that didn't work. I guess i could remove iTunes and reinstall, but i hate to do that. Maybe I should take all the music off and sync and then try putting  it back on? Worked before i put music on there, but then there wasn't much to sync at that time. Anyone know of other possible causes that would make iTunes stop working?

  • Recent freezing and shutting down every down 10-15 minutes and hard to log in to internet very slow

    My son has 2009 Macbook white version and recently (last week or so) freezing all the time, cannot log on to internet, and shuts down every 10-15 minutes. Is there a download (free hopefully to clean it up for any spyware or maleware). He is a student and very busy in University and cannot be without the computer?

    He will need something to back up onto like an external hard drive. The disks are necessary if the hard drive needs to be repaired, you can't repair the boot volume so you need to start up from an install disc and run Disk Utility from there. When you talk to him have him resettle SMC and pram, sometimes unexpected shutdowns can be corrected that way. The freezing is another issue, I'm concerned with the health of his hard drive. Another thing to ask when you talk to him is how much total space and how much free space does his hard drive have?

    Aperture 3 shuts down every time I try to use it after only using it for one minute. Aperture closes then a pop up screen asks if I want to reopen Aperture. If somrone at Aperture didn't keep pushing a stop button for it to close,Apple wouldn't need to ask the stupid question"Do you want to reopen Aperture?" to begin with. Anyone out there having the same annoying problem?? I like Aperture or used to anyway,but if this nonsense continues, I will be forced to buy some other editor besides "No hanging fruit - Adobe photoshop CS5" or "I don't like you so I'm shutting down - Aperture".

    Hello,
    sorry to hear about your troubles, but we will need to have more technical information about your problem to be able to help you:
    There may be several reasons that can cause Aperture to crash on start up:
    You may have imported an image (or video) in an encoding that Aperture does not support, or that is larger than 2 GB, or that is corrupted and Aperture cannot process it
    Your Aperture Library or Preferences may have been corrupted
    Or you are having a system wide problem with your machine.
    Or you may simple be running out of disk space.
    It would help, if you could post the crash log from your last crash. Also, more details on your Aperture Library: Is it managed or references? how large is it? Is it on your system drive or on an external drive?
    What have you done, shortly before the trouble started? Have you imported new images or videos? Did you install any plug-ins or any new software, lile Final Cut?
    Try, if you can get Aperture to launch, if you defer the generation of Previews: Hold down the SHIFT-key immediately after you start Aperture to prevent preview generation for that session. If a damaged image in your library is preventing normal opening, this may allow you to start Aperture. If this succeeds, try to identify the broken image or video among the images you recently imported and remove it from the library.

  • Shutting down every 30"

    I have been using my Mac Air with Spotify and connecting it to the stereo system. It started shutting down approximately every 30 minutes. When it does it even closes all the programs. I think that I have all the settings so that it shouldn't shut down with the power cord connected? I have the Energy Saver setting on NEVER. Is there somthing I'm missing?

    I've had FIOS for about two years and this just started happeneing to my HD set top box. I've gotten three different answers for when to expect delivery of the new box. POOOOOORRRR customer service! I don't expect this to resolve the issue. If it doesn't, I will demand that the outside box be replaced next. I also have three standard set top boxes in the house that are not affected. Verizon seems to be skirting the issue rather than actually trying to solve it. My box shuts down every 5-10 minutes now. And often gets stuck in a restart cycle and won't come back up.

    Safari crashes and shuts down every time I visit Grays Online. Site usually flicks off in under a minute. Anyone else with this problem?

    The website may need more memory than you have available if you are running iOS 5.1.1 on the original iPad. Try some basic troubleshooting steps. Maybe quitting all apps might be the best thing to try.
    Reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons.
    Quit ALL apps completely and restart the iPad. Go to the home screen first by tapping the home button. Double tap the home button and the task bar will appear with all of your recent/open apps displayed at the bottom. Tap and hold down on any app icon until it begins to wiggle. Tap the minus sign in the upper left corner of the app that you want to close. Tap the home button or anywhere above the task bar. Restart the iPad.
    Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button.
    Go to Settings>Safari>Clear History, Cookies and Data. Restart the iPad. Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button.
