Slow and Spinning Rainbow Wheel For Simple Actions

My computer is slow. BASIC actions are slow. File: Open LONG WAIT. SPINNING. Clicking between open windows doesn't make the window I clicked active for MANY seconds! File: SAVE. WAIT. SPINNING.
Imagine how it was speedwise with an Apple II clone. That's what's happening. I used to blame MS Word, which is the worst, but everything is a struggle and unproductive.

Any ideas???

Launch the Activity Monitor utility. Select the CPU tab near the bottom and see what it reports while you're experiencing slow behavior. Also select the "System Memory" tab and see what value you see for "Page outs". The "Disk Activity" tab may also show you something interesting.
If you see high CPU usage, you can identify the culprit(s) by setting the list at the top to "All Processes" and clicking the "% CPU" heading until the highest CPU user is at the top.

  • Spinning rainbow wheel for long periods on File Open commands in Acrobat and Office 365 programs

    Hardware & Software:
    MacBook Pro (17-inch, Mid 2009)
    77GB of free hard disk space
    8GB RAM
    Running OS X Yosemite (Version 10.10.2)
    Over the last few days, when I try to execute a File Open command from Adobe Acrobat or Office 365 programs (even from an innocuous location such as Documents), I get the spinning rainbow wheel for long periods of time (10 seconds to minutes) before I am able to select a file to open. I copied messages from Console after a File Open command for each of Adobe Acrobat and Excel (the selected location was Documents), given below:

    Can anyone give me an idea of what these messages mean and how I can solve this problem?
    If I'm not in the correct Community for this question, could someone kindly tell me where I should re-post?
    Thanks.

    Yes; I have previously connected to an iMac at this location using File Sharing.  However, in my attempts to solve this problem last week, I had already unchecked File Sharing in System Preferences.  Tonight, I also deleted the folder from the window in the File Sharing System Preferences page, then rebooted.  The problem still persists.
    I try not open files across a server line, i.e., I try always to copy a file to the local computer and open it there.  I may have gotten careless and tried to open a file from the Windows server with either or both Acrobat and Office 365.  Although this was an SMB share, is it possible that these programs are now trying to connect to the Windows server on a File Open?
    I had about decided to quit chasing this problem; we spend about two weeks every two months at this Boston location, and I'll be returning to my Florida home this weekend.  So I decided I would see what the situation was when I returned to my native habitat, although I may be chasing this problem again in our trip to the Boston area in April.
    The other thing I wondered (I guess I can't quite let it go), is whether there is a command line in Terminal that would kill all AFP shares.
    In any case, thanks for your help; you're very knowledgeable.

  • Spinning rainbow wheel for some minutes when apps use file open dialogue

    OSX 10.4.4
    Powerbook, home Cable via Airport.
    Whenever an application such as Firefox or Word (the worst) uses the File browse and open file dialog (Finder like window) I get a spinning rainbow wheel for up to two minutes.
    I have tried everything I know to hunt this down, but it happens even when newly booted.
    Finder on the other hand is fine.
    Any clues what I could look at?

    My personal experience is that the whole iDisk/WebDAV/Finder thing is hopeless. I keep thinking it will get better, but it doesn't. I've been waiting since Jaguar, and it keeps being "one step forward, two steps back." I have given up on keeping the "official" iDisk on my hard drive. Instead I disabled the local iDisk, keep my own folder with items for my disk, and just use the freeware Goliath when I want to put something from my local files into my iDisk. You will amazed and how much faster Goliath is, and there will be no more agonizing pauses when you try to open or save something.

  • Slow Macbook Pro with frequent spinning rainbow wheel!

    My Macbook Pro suddenly is very slow especially when using Google Chrome. I usually get the spinning rainbow wheel for most tasks and on chrome it often says "waiting on cache" or "waiting on app cache". I don't think it's just chrome because I have had problems with other applications as well. I've tried repairing disk permissions multiple times as well as deleting browsing history and nothing has solved the problem so far. I had a similar problem earlier in the year when I had to go to a store to get theBRACKET,HDD,FRONT,WITHIR/SLEEP/HDCABLE fixed. Any tips or suggestions would help! Don't really want to have to go back to a store to get this fixed again. etrecheck is below

  • Spinning rainbow wheel

    I got my macbook pro last tuesday. This morning I woke up realizing I didn't plug in my charger so my battery was completely dead. I turned on my laptop and I see a white loading screen with the spinning rainbow wheel for the first time. In the last hour I've seen the rainbow wheel at least three more times. When I do see it, the wheel disappears in 1-2 seconds. It doesn't last long at all but why am I seeing this wheel? The wheel appeared twice when I opened the APP store both times. What exactly can I do???

    I recently installed Tiger, and then applied the most recent updates. The 2008-002 Security Update caused the kind of behavior you are describing to the point where even the attempt to save the html of a small web page would cause my system to hang for anywhere from a couple to a couple dozen minutes (and sometimes even cause the Finder to repeatedly crash). Finally I did an Archive and Install and things returned pretty much to normal, although I do find that I get more spinning beachballs in Tiger - to which I recently moved up - than I did in Panther (usually when saving a file within a web browser, so maybe the Security Update simply exacerbated a problem that was already present).
    Anyway, do you know if this started happening after installing that 2008-002 S.U.?

  • I have a new MacBook(2012). Being a new Mac user, I do not know what to do when Safari doesn't open at all. The icon just bounces up and down and when the cursor is on the top main menu bar it is the spinning rainbow wheel.  Any ideas for help?

    When I try to open safari the icon stats bouncing and then nothing happens other than the cursor turning to a spinning rainbow wheel when it hoovers on the top main menu bar. I have shut down and restart several times. My safari worked yesterday and then today this, but with. I indication of a problem. I can't even get the browser window to open so that I can clear caches or reset anything. When I opened my computer this time I don't even get a bouncing icon. No recognition of selecting the program at all. If I go to spotlight and try to open safari from here I still get no response. Can you help?

    Hi ...
    If you have moved the Safari application from the Applications folder, move it back.
    As far as the cache goes, there's a work around for that when you can't empty the Safari cache from the menu bar.
    Go to    ~/Library/Caches/com.aple.Safari.Cache.db.  Move the Cache.db file to the Trash.
    Try Safari.

  • My computer is extremely slow, with the rainbow wheel appearing with every click. It is one year old, and has all the most recent updates. Why is it so painfully slow?

    My computer is extremely slow, with the rainbow wheel appearing with every click. It is one year old, and has all the most recent updates. Why is it so painfully slow?

    That sounds horrible. There are a number of reasons it could occur.
    The first thing to do is ensure you have adequate backups, because what you describe can be a symptom of impending disk failure.
    To help determine the possible causes of this behaviour read the following. None of what follows is intended to fix anything, but it will provide the additional information required to advance troubleshooting. There are four separate parts to it; read everything first.
    Boot OS X Recovery by holding ⌘ and r (two fingers) while you start your Mac. At the Mac OS X Utilities screen, select Disk Utility. Select your startup volume (usually named "Macintosh HD") and click the Repair Disk button. Describe any errors it reports in red. If Disk Utility reports "The volume Macintosh HD appears to be OK" in green then you can be reasonably (though not completely) assured your hard disk is in good working order.
    When it finishes restart your Mac and test again for operation. If it's still not behaving as you expect it should, please post the results of EtreCheck in accordance with the following instructions:
    Apple Support Communities contributor etresoft wrote a very useful app to quickly gather certain system information that may help point to a cause of this problem. Read about it here. It contains a link to download EtreCheck. Don't download it from anywhere else (such as may be found by following the results of an Internet search).
    Click Open - etresoft contributes to this forum frequently and can be considered a trustworthy developer.
    It will take a moment to run as it collects its data.
    Copy and paste its output in a reply.
    Do not be concerned about anything that says "Problem" or “failed” or anything else that may appear in red.
    EtreCheck was designed to remove any personal information (such as your computer's name and serial numbers) but if you see anything that looks like an email address or any other personal information that should not be divulged to others, please delete or obscure that information when you post the reply.
    When you are finished with EtreCheck, quit the program. It occupies very little space, and you can keep it or drag it to the Trash as you wish.
    After completing the above please determine if the problems also occur in "Safe Mode":
    Safe Mode or "Safe Boot" is a troubleshooting mode that bypasses all third party system extensions and loads only required system components. Read about it: Starting up in Safe Mode
    You must disable FileVault before you can start your Mac in Safe Mode.
    Starting your Mac in Safe Mode will take longer than usual, graphics will not render smoothly, audio is disabled on some Macs, and some programs (iTunes for example) may not work at all.
    Merely starting your Mac in Safe Mode is not intended to resolve the problem, it's to observe its performance without certain additional components.
    To end Safe Mode restart your Mac normally. Shutdown will take longer as well.
    System performance problems for reasons that cannot be isolated to any other cause justify an SMC reset. Be sure to read the procedure carefully and follow all the steps exactly as written, even if they seem inapplicable or trivial.

  • HT1338 My Mac book Pro is running very slow and the rainbow ball is appearing all the time. Any suggestions for clean up??

    My Mac book Pro is running very slow and the rainbow ball is appearing all the time. Any suggestions for clean up?? I have the OS X Lion system.

    As well as what a brody asked :
    - do you need more RAM? (run Activity Monitor and see how much free RAM - green - is available)
    - do you Restart fairly regularly, e.g. at least once a week, to clear out any swap or temporary files?
    - do  you need to do maintenance, e.g. clearing out caches and unused logs, etc?

  • IPhoto opens but then the spinning rainbow wheel appears and I can't do anything. I have opend iPhoto with the Option key pressed and rebuilt the library and it still happens.  I want to at least access my photos and copy them to an external drive.

    iPhoto opens but then the spinning rainbow wheel appears and I can't do anything. I have opend iPhoto with the Option key pressed and rebuilt the library and it still happens.  I want to at least access my photos and copy them to an external drive. Anyone have ideas on how to get to them?

    Make a temporary, backup copy (if you don't already have a backup copy) of the library and try the following:
    1 - delete the iPhoto preference file, com.apple.iPhoto.plist, that resides in your
         User/Home()/Library/ Preferences folder.
    2 - delete iPhoto's cache file, Cache.db, that is located in your
         User/Home()/Library/Caches/com.apple.iPhoto folder. 
    Click to view full size
    3 - launch iPhoto and try again.
    NOTE: If you're moved your library from its default location in your Home/Pictures folder you will have to point iPhoto to its new location when you next open iPhoto by holding down the Option key when launching iPhoto.  You'll also have to reset the iPhoto's various preferences.

  • Spinning rainbow wheel & all blue wheel. What gives?

    I'm usin a Mid-2012 MacIntel tower that is a 2.8ghz Quad-Core Xeon with 20GB of 1066 DDR3 RAM, OS 10.8.2 and using the AIR Radeon HD 5770 with 1024MB of RAM. So, In my mind this is a pretty fast system but recently the spinning rainbow wheel has been appearing as well as the spinning all blue wheel. The system is really dragging. I've done SMC resets, zapped the PRAM and thinking of doing a PMU reset. I've checked activity monitor also. What I see is that Safari Web content, Safari, iTunes, mds, and something called kernel_task are using the most RAM. The kernel_task is eating up 1.31GB!! Even if I quit Safari and iTunes, I'm getting a lot of spinning wheels and just slow responses. I click on something and it actually highlights almost 10 seconds later. I've tested my RAID and internal drives and they appear fine. All are Serial ATA. This only happend after installing Mountain Lion. Is there anything else I can do other than go back to the old school days of running one program at a time. Can I quit out of this kernal_task operation or is that a bad move?

    Check your
    Safari > Preferences > General ...
    ... and make sure you are removing History Items: After one Day
    Safari and many other Browsers will carry around every stinkin' website you visited for months, and their RAM foot print grows to be enormous. Stuff older than that can be searched for more easily than scrolling through your History.
    If you use topsites, choose LARGE views, then fewer fit in the window and it will not works so hard or use so much memory keeping track of them.
    In 10.7 especially, Applications whose windows are closed are left running, chewing away at your RAM used. Try to remember to Quit unused Applications rather than just closing their windows.
    RE: The display you showed in the screenshot. Click on the %-CPU column to sort by biggest CPU hog at the top. Sometimes that is very enlightening. Things in double-digits may need to be looked at.

  • IBook freezes on Apple logo white screen, NO spinning rainbow wheel

    Hello,
    I bought my iBook 12" 1.33Ghz used in May. It has worked flawlessly until two nights ago when I was surfing the web via Airport. Everything started to take forever to load, the spinning rainbow wheel appeared several times, and applications took minutes to switch between. Since the iBook had been on for a few days, I thought it was time to do a reboot to fix whatever was backlogged in the system. It didn't want to respond, so I force quitted all programs. I could click on the blue logo and hit shut down or restart, but they didn't do anything towards a shut down. I finally held the power button to force a shut down. Ever since, when I power up, I get the Apple chime, a gray screen (for less than a second) and then the white screen with the gray Apple logo. There is NO spinning rainbow wheel, as others with similar sounding problems have mentioned. I've cleared the PRAM and PMU, but they didn't help anything. Holding Shift on startup does not do anything differently. It still just freezes on the Apple logo for hours. I did not get a Mac OS X startup disk with my computer. What else can I do to troubleshoot this? Please help, this is my first Mac, and up until 3 days ago, I had all but sworn off PC's, now this thing is acting up too!
    Also, I'm guessing which version of Mac OS X I have, is there anyway to confirm without booting? Holding option is the only thing I have found to give me a different startup process, and the mouse pad is very sluggish and there's a watch logo for 20 seconds or so on it.

    Hello! Since you don't have the startup disk your best shot is using fsck. Tom
    when you re-start, hold down the apple key AND the "S" key You'll start up into a command line interface.. it'll look strange but just hang in there. When it's done booting up, you should see something that looks like this: localhost:/ root# at this point, type in 'fsck -f" please note the space before the dash, and of course, ignore the quote marks, then hit return You computer will no go thru some low level checks on your HD. Most likely you'll get a list of a few files that have problems and this procedure will fix them. This should take about 2 or 3 mins, so don't be in a rush. When the line says "VOLUME WAS MODIFIED", this means that changes were made. At this point you should be back at the same localhost:/ root# prompt. run fsck -f again. Wait for it to finish. if you continue to get the "Volume was modified" message, continue to run fsck -f until you'll get a prompt that says The Volume(your HD) appears to be ok, again with the localhost:/ root# prompt. AT this point, type reboot, hit enter and your computer will start up normally. This is not difficult, but you may want to give it a shot when your feel you have a few moments where you can attempt something new and not stress too much.

  • Iphoto not working - i get spinning rainbow wheel

    My iphoto does not work.. It has suddenly stopped!
    When I open iPhoto, the spinning rainbow wheel comes up, and I am unable to do anything - so I have to force quit..
    I'm not sure what to do? I have the extended warranty for my laptop - it is less than 12 months old
    iTunes also wont update to the latest version either.....
    Any suggestions on what I should do?
    Im mostly concerned about iPhoto...

    Hi,
    I've had this issue twice now when importing photo's from my iPhone.
    First time I rebuild library from backup. The backup did not contain the imported pictures so iPhoto worked fine again.
    Yesterday I "retried" to import. So the problem re-occured (duh).
    This time however I noticed there was an "update icon" next to places when iPhoto froze.
    So I decided to disable automatic "Lookup Places". The trick however is to get into a responsive iPhoto.
    For this: start iPhoto while holding the Option (or alt) key, create a new library, open iPhoto using this new library, go to Preferences, Advanced Tab, set Look up Places to " never".
    Close iPhoto, open again using Option (or alt) key (because the new, empty, library has been set to default automatically), select your original library and your iPhoto should be fine again.
    This did the trick for me. Hope this helps.
    Cheers!

  • Spinning rainbow wheel every time I connect phone to itunes....

    I have an iphone (I'm not sure the model but I bought it in January). Did the recent software update and now every time I connect my phone it recognizes it in itunes and immediately starts with "verifying iphone" but in less than a minute if I click on anything in itunes or not it starts with a spinning rainbow wheel and the only way it stops is if I force quit itunes.
    I can't update, change, add, delete anythig on my phone and also as a result the itunes/ipod function on the phone doesn't work and also freezes up.
    Someone suggested I might have a bad file on there somewhere, like an mp3 or what have you, but how would I even go about deleting the music or the files if I can't even connect to itunes?
    Can I do a factory restore without connecting as well?

    I would try a normal restart first and if that doesn't help, try a reset.
    Restart iPhone: Press and hold the Sleep/Wake button until the red slider appears. Slide your finger across the slider to turn off iPhone. To turn iPhone back on, press and hold the Sleep/Wake until the Apple logo appears.
    Reset iPhone: Press and hold the Sleep/Wake button and the Home button at the same time for at least ten seconds, until the Apple logo appears.
    If they don't work you can do the factory reset (without connecting) and when it's complete you'll have to register the phone again with iTunes.

  • Is there any reason or my why cursor is stuck on the spinning rainbow wheel?

    Lately my macbook has been freezing, and I'm thinking that it's being overloaded. Most of the time the cursor is stuck on the spinning rainbow wheel, but it will eventually return back into the arrow. It's currently stuck as the spinning wheel, but I am able to click and access sites. Is there anything I should do to get this checked?
    EDIT: When I open a new tab, the cursor goes back to normal. Is there any reason why it is doing that in the other tab?

    Hi,
    Use the PC KB and hold Windows key + r key at bootup.
    Bootup holding CMD+r, or the Option/alt key to boot from the Restore partition & use Disk Utility from there to Repair the Disk, then Repair Permissions.
    If that doesn't help Reinstall the OS.
