Mavericks is extremely slow. NetFlix used to stream just fine until I loaded the "upgrade." What is the problem with this OS?

Mavericks is extremely slow. NetFlix used to stream just fine until I got the "upgrade." Everything is slower now, and I have plenty of RAM. Any insights?

Hello Sunny James,
I would be concerned too if my iMac was running slowly after upgrading to Mavericks.  I found a couple of articles I recommend to help isolate and troubleshoot this issue.
I recommend reviewing this article first for possible causes of the slowness:
OS X Mavericks: If your Mac runs slowly

You can further isolate the issue by determining if it is only happening in your user account or if it is happening system-wide:

  • I originally bought an iMac 17 which crashed. Have now bought a second-hand iMac20. This has less preinstalled software, no iDVD, no iPhoto, Garageband, no iWeb.  Can I use my original discs to restore these options to my new computer? Problems with this?

    You might be able to depending on the age of the disc and the model of your newer used iMac. Only way to tell is to pop in the DVD and see if you can install the iLife programs.

  • HT3702 I have almost $300 worth of charges on a game that I just downloaded from iTunes.  I have never had a problem with this, I do have a 5 year old using my Ipad, but $300. I was told that you need to authorize with a passcode again before additional p

    I have so many charges that just came in this morning, I have tried multiple times to get in touch w/ Apple by chat, online and phone with absolutely NO LUCK.  I purchased a stupid game for my 5 year old, but somehow I have $300 in charges this morning..  Who can I get in touch with?  I thought that you needed additional authorization to charge anything else?  If I cannot get help, I will cancel all of our iTunes and everyone can buy a gift certificate with $10 on it for all future use.
    Does anyone have a phone number where I can talk to a live person? or a chat that actually works?

    You can try contacting iTunes Support and see if they will refund or credit you : http://www.apple.com/support/itunes/contact/ - click on Contact iTunes Store Support on the right-hand side of the page, then Purchases, Billing & Redemption. The contact methods that are available vary by country (and possibly by time of day), but you might get options on that page.
    You can turn off in-app purchases on your iPad via Settings > General > Restrictions > In-App Purchases 'off', and depending upon what version of iOS that you have on it you may have a Require Password option on the Restrictions screen that you can set to 'Immediately' (there is a default 15 minutes during which it doesn't need to be re-entered).

    when i attempt to open Firefox Mail, I get a popup (yellow background) with the heading "There is a problem with this message". We are sorry, but Yahoo Mail has encountered a temporary problem, referring to Temporary Error 4. It goes on to suggest that I might solve the problem by going to Yahoo Help Page.

  • IPhone 6 and 6 plus camera extremely slow when using flash

    I have noticed that the iPhone 6 and 6 plus camera is extremely slow when using flash, it is definitely slower than iPhones 5 and 5s.
    Any explanation/solution for this?

    I Have done some more testing and it seems turning off HDR resolves the issue

  • Hi, I want to use my Capsule just as a back up via wireless. How do I set this up without connecting it with an ethernet cable to either a router or the iMac??

    Hi, I want to use my Capsule just as a back up via wireless. How do I set this up without connecting it with an ethernet cable to either a router or the iMac??

    I misunderstood what Time Capsule is and had hoped for a wireless backup device that didn't have to be connected to the router.
    The TC is a wireless backup device.. it does not need to be connected to the main router..
    The problem is the computer.. not the TC.. the computer has only one wireless card.. if your current internet is by wireless.. then you must choose.. internet or backup.
    But my other suggestion will work.. get a wireless USB stick compatible with Mac OS.. there are plenty and cheap.. since you are in the same room as the TC they will work fine.. plug it in and load the driver.. taint hard.
    You should do the first backup by ethernet though.. wireless is too slow.. once you have that, you will do fine.
    Search ebay for wireless n usb.. Mac compatible..
    http://www.ebay.com/itm/New-EDUP-Mini-Wireless-11N-300M-USB-LAN-Card-WiFi-Adapte r-Nano-Card-Soft-AP-/150864362939?pt=US_USB_Wi_Fi_Adapters_Dongles&hash=item2320 377dbb#ht_3553wt_1165
    As you can see.. they are getting smaller and neater.
    I have no idea if it works .. haven't tried one.. but I have used USB wireless stick on the Mac to overcome this issue.
    You will need to set static IP .. not hard but you need to set specifics if you do buy one post again for the setup.

  • [32282.000367] firefox:2114 freeing invalid memtype c02f2000-c0302000 I get this from system log using latest version of Firefox: What kind of problem is this?

    I get this from system log using latest version of Firefox:
    [32282.000367] firefox:2114 freeing invalid memtype c02f2000-c0302000
    What kind of problem is this?
    Anyway Firefox seem to be working correct. I would like to be sure that it'snt a security problem.

    Thanks a lot for your swift response. And sorry if it was a bit too hectic to go through my detailed query (which I did because it was misunderstood when I asked previously). As I've mentioned above, I was informed that updating to 5.0.1 would '''require''' me to '''delete''' the current version and then install the new one. And doing so will involve losing all my bookmarks. I guess I should have been more specific and detailed there. By losing, I didn't mean losing them forever. I'm aware that they're secured in some place and deleting and installing the software doesn't harm its existence. What I meant that if I install the new version, I'd have to delete the old one. And after installing the new version, I'd have to transfer them (bookmarks) back from wherever they are. Get it? When it updated from 3.6.9 to 3.6.13, and from 3.6.13 to 3.6.18, I didn't need to follow that process. They were already present on their own.
    BTW, I'm having no problems with 3.6.18 but after learning about the existence of version 5.0.1, I'm a bit too eager to lay my hands over it.
    Thanks for your help; hope this wasn't extremely long.

  • I have a 2008 imac with snow leopard.  i installed update 10.9.3 not realizing it's best for Maverick's users.  Now my Itunes 11.2.2 won't burn playlists to CD.   Anyone else with this problem?  CAn I uninstall the 10.9.3 update?

    i have a 2008 imac with snow leopard.  i installed update 10.9.3 not realizing it's best for Maverick's users.  Now my Itunes 11.2.2 won't burn playlists to CD.   Anyone else with this problem?  CAn I uninstall the 10.9.3 update?  Also my HP scannerwill not save the displayed scanned document since this update!  it just saves gray.

    If you have your old system backed up then erase the drive and restore your backup. If you don't have a backup then backup your entire Home folder. Erase the drive and install Snow Leopard after which you can restore your Home folder from the backup.
    Clean Install of Snow Leopard
    Be sure to make a backup first because the following procedure will erase
    the drive and everything on it.
         1. Boot the computer using the Snow Leopard Installer Disc or the Disc 1 that came
             with your computer.  Insert the disc into the optical drive and restart the computer.
             After the chime press and hold down the  "C" key.  Release the key when you see
             a small spinning gear appear below the dark gray Apple logo.
         2. After the installer loads select your language and click on the Continue
             button. When the menu bar appears select Disk Utility from the Utilities menu.
             After DU loads select the hard drive entry from the left side list (mfgr.'s ID and drive
             size.)  Click on the Partition tab in the DU main window.  Set the number of
             partitions to one (1) from the Partitions drop down menu, click on Options button
             and select GUID, click on OK, then set the format type to MacOS Extended
             (Journaled, if supported), then click on the Apply button.
         3. When the formatting has completed quit DU and return to the installer.  Proceed
             with the OS X installation and follow the directions included with the installer.
         4. When the installation has completed your computer will Restart into the Setup
             Assistant. Be sure you configure your initial admin account with the exact same
             username and password that you used on your old drive. After you finish Setup
             Assistant will complete the installation after which you will be running a fresh
             install of OS X.  You can now begin the update process by opening Software
             Update and installing all recommended updates to bring your installation current.
    Download and install Mac OS X 10.6.8 Update Combo v1.1.
    Or you can:
    Try these in order testing your system after each to see if it's back to normal:
    1. a. Resetting your Mac's PRAM and NVRAM
        b. Intel-based Macs: Resetting the System Management Controller (SMC)
    2. Restart the computer in Safe Mode, then restart again, normally. If this doesn't help, then:
         Boot to the Recovery HD: Restart the computer and after the chime press and hold down the
         COMMAND and R keys until the Utilities menu screen appears. Alternatively, restart the
         computer and after the chime press and hold down the OPTION key until the boot manager
         screen appears. Select the Recovery HD and click on the downward pointing arrow button.
    3. Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the Utilities menu. Repair the Hard Drive and Permissions as follows.
    When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
         Reinstall the 10.9.3 update: OS X Mavericks 10.9.3 Update (Combo).
    4. Reinstall Lion/Mountain Lion, Mavericks: Reboot from the Recovery HD. Select Reinstall Lion/Mountain Lion, Mavericks from the Utilities menu, and click on the Continue button.
    Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
    Reinstall the 10.9.3 update: OS X Mavericks 10.9.3 Update (Combo).

  • I had a Tascam US 122 usb interface, but it didn't work with OSX Mavericks. What model would work with this? Would the US-144 mkii work with my system?

    I had a Tascam US 122 usb interface, but it didn't work with OSX Mavericks. What model would work with this? Would the US-144 mkii work with my system?
    Thanks!

    You didn't mention the kind of track in GB you are trying to create, but if you are connecting the keyboard with a guitar chord to the Tascam, you will need to set up a Real Instrument Track in GB to hear anything. If your keyboard has a midi out, use a midi cable to the midi input of the Tascam, create Software Instrument Track, and you will hear something. But with a guitar chord, it won't send the right signal to a Software Instrument Track. The headphone jack in the Tascam monitors the signal coming back to it out of GB (if you choose the US-122 as your monitor in GB's preferences), so you wouldn't hear your keyboard if the track is not set up correctly. It could be the drivers, but since you didn't mention the type of keyboard or the type of GB track, I thought that might be a possible answer as well.

  • My Bluetooth USB wireless transmitter for my portable speakers has quit working.  Preferences says, "The selected device has no output controls", it used to work just fine.  Can anybody help?

    My Bluetooth USB wireless transmitter for my portable BT speakers has quit working.  Preferences says, "The selected device has no output controls", it used to work just fine.  The internal and a pair of wired external speakers work fine.  Can anybody help?

    Just tested something and it worked.
    If I put the headphones all the way in, the mac recognizes it as a digital output.
    But if i don't put it all the way in, it recognizes it as headphones and works perfectly.
    It's probably this crappy headphones.
    If anyone has the same problem, try this out.

  • I have a mid-2009 MBP and I've been using my BOSE Companion 20 with it for about half a year now. It was fine until recently, when i want to adjust the volume using the pod on the BOSE Companion 20, it will cause like a surge in volume, spiking it up

    I have a mid-2009 MBP and I've been using my BOSE Companion 20 with it for about half a year now. It was fine until recently, when i want to adjust the volume using the pod on the BOSE Companion 20, it will cause like a surge in volume, spiking it up and down. It will not stablise itself! It's very fustrating. Anybody with the same issue?

    I have the BOSE Companion 5 speakers and have had the same problem. I've searched everywhere and gotten nowhere. My speakers are way past their warranty, so calling Bose would probably get me no where either. Only thing I can think of is that the speakers overheat which causes the spikes in the volume. I've tried unplugging them for a few minutes and then plug them back on. The problem does go away, but after about 5 minutes, same problem.
