Since upgrading to Mavericks I am finding that I am lucky to get 2 hours (when connected to WiFi) of use from my macbook Pro.

Since upgrading to Mavericks I am finding that I am lucky to get 2 hours (when connected to WiFi) of use from my Macbook Pro.  I have turned off Bluetooth ( which was not an issue previously), uninstalled Chrome, again not an issue before I upgraded, and have not seen any improvement.
I was using an older OS system (Snow Leopard) on my 2010 Macbook Pro.  I am wondering now if the upgrade was an unwise move?

jbuckworth,
which apps do you run under battery power? Are any of them identified as “apps using significant energy” when you click on the battery icon in the menu bar? If you have a 15-inch or 17-inch model, are your apps using the discrete GPU (which consumes more power than the integrated GPU)?
How many charge cycles has your battery accumulated?
How long have you had Mavericks installed? Is Spotlight still reïndexing your boot drive? (It does that whenever your OS is upgraded, because so many files change in an OS upgrade.)

  • Since upgrading to Maverick I cannot send/share photos through iPhoto. Dropbox says "not connected to server". All other online email activities work just fine.

    Since upgrading to Maverick I cannot send photos while in iPhoto.  Dropbox says I am not connected to server.
    All other internet email activities work just fine.

    And again why do you think Dropbox is involved in any way?  There is no connection of any sort between iPhoto and Dropbox
    THis sounds like you either need to (my personal suggestion) change your email client to Mail in the iPhoto preferenceemail if you want to use the iPhoto client under the accounts tab delete your account and re-enter it

  • Since upgrading to Mavericks, 10.9.1, pictures that come attached to emails no longer display.  There is only a blank space that after about 1 minute, has a small box with a question mark.  How can I go back to attached images?

    Since upgrading to Mavericks, 10.9.1, pictures that come attached to emails no longer display.  There is only a blank space that after about 1 minute, has a small box with a question mark.  Double clicking on the box will open the image in a separate window.  It's very slow and tedious for multiple images.  How can I go back to attached and displayed  images?  If I click on "Forward", the images appear instantly in the email to be forwarded.

    Scott,
    My problem seemed to fix itself.  Or, by shutting down the computer one night, instead of putting it to sleep, may have reset something.  Since updating to Mavericks, I always (or usually) let the computer sleep overnight or anytime I'm walking away from it.  A few days ago, I was updating notes for my kids about how to find all my stuff and how to turn on my computer, so I wanted to rewrite the start-up procedures for the iMac, just in case they ever need to.  Well, I shut it down one night so the following morning, I could write down each step.  Lo and behold, the images, etc. are all there again!  Solved, but I'm not sure why.

  • Since upgrading to mavericks, JPEGs that I open in Preview are scrambled.  PDFs work ok.

    I use a mid 2011 Mac and since upgrading to Mavericks I cannot open jpeg files using Preview, they simply appear as a scrambled mess.  The actual jpeg files are ok as I can open them using other applications.  Note, I can view pdfs using Preview, its just the jpegs that are the problem.  Any ideas?

    Thanks etresoft, I reinstalled Mavericks and Preview works perfectly now.
    Cheers!!

  • I upgraded from snow leopard to mavericks only to find that my backup files of all my CS3 indesign, illustrator, photoshop wo't run, how do I uninstall mavericks and get my old system back

    I upgraded from snow leopard to mavericks only to find that my backup files of all my CS3 indesign, illustrator, photoshop wo't run, how do I uninstall mavericks and get my old system back.  I retired from graphics a few years back but still have old clients I do work for and maintain files for.  Would not have upgraded if I had known of the incompatability.

    You did not due any due dilligence to investigate if your legacy apps would run, you should upgrade your apps. However if you feel you have to downgrade back to SL then click

  • Cannot Access Disks on Time Capsule Since Upgrading to Mavericks

    Hey folks...
    So I've had this set up for several years, and it's worked out well. I have a time capsule with an external (self-powered) harddrive connected to it via USB. I usually access it via ethernet as the connection is more speedy than wifi, and my laptop generally remains stationary. For what it's worth, I'm using a Macbook Pro (mid-2010), with the original time capsule (500gb) as well as a connected Western Digital (1tb) external harddrive.
    Since upgrading to Mavericks, however, I have not been able to consistently access the remote disks, either by wifi or ethernet connection.  The time capsule shows up under my "shared" section of the finder window, but the drives (which are usually visible and accessible from within the time capsule) are not there. Strange enough, when I go into my Airport Utility for Time Capsule preferences, the disks are visible under the "disks" section.
    The time capsules' firmware is up to date, as well as the laptop's. I have tried reseting the time capsule as well as my computer in addition to simply unplugging/plugging it back in. I was able to access the disks on a fluke once in the last few days, but after moving the computer away from it's standard spot, the disks are once again no longer accessible.
    I had Server 2.0 but am unable to use it since upgrading the OS and haven't purchased Server 3.0. Any suggestions for solutions? Could residule configurations having to do with the Server functionality be affecting it? I'm guessing it is something to do with Mavericks.  Thanks for any help or feedback.
    Mitchel

    I don't have a guaranteed solution to your problem, just some suggestions:
    1) Try powering down the Time Capsule for at least 15 minutes, then plug it in again and see if it works better.
    2) If you suspect that heat might be a problem, try raising the Time Capsule to give better air flow below it.  I have mine on an inverted plastic-coated-wire basket of the type used to organize kitchen drawers.
    3) If AirPort Utility can "see" the Time Capsule, you should be able to use the "archive" function (in the Disks panel, Disks tab) to write the disk's contents to a drive connected to the Time Capsule's USB port.
    4) In the worst case, you should be able to access the files on the Time Capsule's disk by opening up the Time Capsule, removing the disk drive, mounting the drive in an external enclosure, and attaching the enclosure to your Mac.

  • Since upgrading to Mavericks, my Canon MP980 printer no longer works. I've tried deleting the printer and adding it again. the process ends with my mac saying the software is not currently available from the software update server.

    Since upgrading to Mavericks, my Canon MP980 printer no longer works. I've tried deleting the printer and adding it again. I've downloaded the driver software from Canon. My Mac dropbox tells me "the selected printer software is available from Apple", but when I click to download it, the process ends with my mac saying the software is not currently available from the software update server.

    Open Finder and click on Go > Go to Folder. Then type
    /Library/Printers/Canon
    and press Enter. This will show the BJPrinter and iJScanner folders. You could try moving or trashing this folder and then installing the driver that you downloaded from Canon again.

  • Macbook pro running painfully slowly since upgrade to Mavericks and worse since Yosemite

    Hi, since upgrading to Mavericks my previously excellent 2011 Macbook Pro is running painfully slowly, and things have only got worse since the upgrade to Yosemite. It takes anything up to 10 minutes to get fully functional from opening the lid on standby, can take a good 5 minutes to connect to wifi, and I am getting stuck with constant spinning beach balls. I've cleaned things up, and deleted anything unnecessary so I have adequate space on the HDD but this doesn't seem to make any difference, and I'm not running any particularly memory hungry software. It was working perfectly before these upgrades and I'm really wishing I could just downgrade back to Mountain Lion now! I'm no expert so could really use some help. Do I just need more RAM or is this something more complicated?
    I've run Etresoft and here are the results (I note there is some adware listed on Safari, but I don't use it ,using Chrome and Firefox instead):

  • Problems downloading movies since upgrading to mavericks

    Ever since upgrading to mavericks when it was first released, I have had nothing but problems downloading movies in iTunes. What normally would take no more than 30 minutes to download a movie and iTunes extras has now turned into waiting more than 3 hours with no less than 4 error messages saying iTunes cannot download the movie and I have to relaunch iTunes or reboot my entire system. It is getting quite annoying and I can't seem to find a solution.
    Any help would be greatly appreciated.
    Thank you in advance.

    I upgraded to Mavericks on two computers and have display problems too! I have CC on one Macbook Pro (2011) and CS6 on another (2012) and I'm now almost positive my display problems are triggered by InDesign. I don't have to be doing anything special, and I don't have to be working in InDesign at the time, but InDesign has to be open and I get things like this:
    Once it turns magenta or green, that's when I have to boot the system. I can still work with the glitchy display before it turns colors and if I'm still able to quit InDesign while it's glitching, the display goes back to normal. Same on both computers and the 2011 one has a new logic board in it.
    At first I thought it had something to do with connecting my hard drive or my external display, but the display issues happened with both computers with nothing hooked up. Those are ruled out now. I took my 2012 computer to Apple and they told me it was a software issue and all my hardware is ok. Obviously they didn't fix the software issue because it's still happening.
    This is not normal and needs to be fixed soon!

  • Since upgrading to Mavericks I have to force shut down to close frozen applications

    Hi all,
    Since upgrading to Mavericks I have experienced several times that sometimes when an application close a simple force quit is not enough. The application will disappear from my dock but remain on screen with the spinning ball, and any instances of the application I try to open will also freeze instantly. The only way to clear them is to do a force shut down via the power button on the back of my computer. I have experienced this with Mail, VLC and Finder so I do not think this an issue with a specific program. If anyone is having the same problem or has an idea of how to fix it, it would be much appreciated

    Please read this whole message before doing anything.
    This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
    Step 1
    The purpose of this step is to determine whether the problem is localized to your user account.
    Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
    While logged in as Guest, you won’t have access to any of your personal files or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
    Test while logged in as Guest. Same problem?
    After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
    *Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
    Step 2
    The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login, by a peripheral device, or by corruption of certain system caches.
    Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. Note: If FileVault is enabled on some models, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
    Safe mode is much slower to boot and run than normal, and some things won’t work at all, including sound output and Wi-Fi on certain models.  The next normal boot may also be somewhat slow.
    The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
    Test while in safe mode. Same problem?
    After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of steps 1 and 2.

    Since upgrading to Mavericks, I have been unable to sync devices (specifically ipad mini and iphone 4s) to my MId 2013 Imac . They wil rapidly connect and disconnect, and I'm unable to do anything with the device. This happens with both USB ports.  Any suggestions?
    MacBook Air, OS X Mountain Lion (10.9.1)

    Obviously, syncing an iOS device with iTunes over USB is still supported in Mavericks. Calendar and contact syncing with iTunes is no longer supported. That has nothing to do with your problem.
    Launch the Console application in any of the following ways:

    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
    ☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
    Paste into the Terminal window (command-V). I've tested these instructions only with the Safari web browser. If you use another browser, you may have to press the return key.
    The command may take a noticeable amount of time to run. Wait for a new line ending in a dollar sign (“$”) to appear.
    A TextEdit window will open with the output of the command. Normally the command will produce no output, and the window will be empty. If the TextEdit window (not the Terminal window) has anything in it, stop here and post it — the text, please, not a screenshot. The title of the TextEdit window doesn't matter, and you don't need to post that.
    Step 2
    There are a few other possible causes of generalized slow performance that you can rule out easily.
    Disconnect all non-essential wired peripherals and remove aftermarket expansion cards, if any.
    Reset the System Management Controller.
    Run Software Update. If there's a firmware update, install it.
    If you're booting from an aftermarket SSD, see whether there's a firmware update for it.
    If you have a portable computer, check the cycle count of the battery. It may be due for replacement.
    If you have many image or video files on the Desktop with preview icons, move them to another folder.
    If applicable, uncheck all boxes in the iCloud preference pane. See whether there's any change.
    Check your keychains in Keychain Access for excessively duplicated items.
    Boot into Recovery mode, launch Disk Utility, and run Repair Disk.
    If you have a MacBook Pro with dual graphics, disable automatic graphics switching in the Energy Saverpreference pane for better performance at the cost of shorter battery life.
    Step 3
    When you notice the problem, launch the Activity Monitor application in any of the following ways:
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
    ☞ Open LaunchPad. Click Utilities, then Activity Monitor in the icon grid.
    Select the CPU tab of the Activity Monitor window.
    Select All Processes from the View menu or the menu in the toolbar, if not already selected.
    Click the heading of the % CPU column in the process table to sort the entries by CPU usage. You may have to click it twice to get the highest value at the top. What is it, and what is the process? Also post the values for User, System, and Idle at the bottom of the window.
    Select the Memory tab. What value is shown in the bottom part of the window for Swap used?
    Next, select the Disk tab. Post the approximate values shown for Reads in/sec and Writes out/sec (not Reads in andWrites out.)
    Step 4
    If you have more than one user account, you must be logged in as an administrator to carry out this step.
    Launch the Console application in the same way you launched Activity Monitor. Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
    View ▹ Show Log List
    from the menu bar.
    Select the 50 or so most recent entries in the log. Copy them to the Clipboard by pressing the key combinationcommand-C. Paste into a reply to this message (command-V). You're looking for entries at the end of the log, not at the beginning.
    When posting a log extract, be selective. Don't post more than is requested.
    Please do not indiscriminately dump thousands of lines from the log into this discussion.
    Important: Some personal information, such as your name, may appear in the log. Anonymize before posting. That should be easy to do if your extract is not too long.
