Upgraded to OS X Yosemite - Slow machine

I upgraded my MacBook Pro on friday the 17. October to OS Yosemite, but the last thing I did was to make a backup by Time-Machine.
The first experience with OS X Yosemite was my machine was very very slow. The startup and every command or startup of an application was so slow that it was unusable. SO I started to look into forums here on Apple and other sites around internet. Many things where written about slow machines (and many surely worked fine but who writes a comment - Works fine?). Some indications where FileVault=on (when no SSD disc) and many indications on graphics (external screens). All this might be true but I also experienced when I used OS X Yosemite all applications running on a single screen on my local MacBook Pro (2008 model previously happy running Maverick), it seemed OK but still some slower than Maverick. When I started several screens and put my applications into these several screens the machine was very much slowed down. Even so I must admit I lost patience on OS X Yosemite as there was to much OS hanging (cursor loops) and seems to be locked into kernel processes so it was very slowed down. So I restored Maverick, and now it is fine.
I hope this can help to solve the "slow down" issues on OS X Yosemite so we again can upgrade these fine machines :-)
Good luck everyone!

I have stated before it was´t necessary as reinstallation of OS X Yosemite was doing the job. But after a week usage it started to do its delays and problems again, so I started your process of "solving Yosemite memory leaks and CPU usage". Then My Yosemite was O´Kai again so I´m happy. But I wonder for how long now?
Anyway Thnx for your guidance!

  • Upgrade to Yosemite Slowed down computer substantially

    Hi All,
    I recently upgraded my MBP (mid-2009) to Yosemite.    I noticed that people have been using EtreCheck to determine what is the root cause of these Yosemite upgrade slowdowns.   My issue is that I am having difficulty interpreting the output file.   Any help and recommendations would be appreciated.
    Here is the file:

    Hi, I have a macbook pro 17" 2.4ghz intel core 2 duo 2007, will upgrading to Yosemite slow me down or create problems with my Iphone or other app ?

    Yes, i do not suggest upgrading right now. There is some software malfunction or glitch that spontaneously shuts down this specific model. I upgraded and it was a pain to downgrade and make my mac usable again.

  • I can't use Time Machine now that I have upgraded to OS X Yosemite

    Ever since I have upgraded to OS X Yosemite, I have not been able to use Time Machine to backup my hard drive.  When I back up using my wireless network, the connection is dropped at some point in the backup process.  I tried a direct connection to the Time Capsule and got a blinking yellow light on the Time Capsule.  What can I do to rectify this situation (other than buying a knew Time Capsule)?

    I-Photo won't open even though I have upgraded to OS X Yosemite and downloaded the I-Photo upgrader.
    But have you run the the iPhoto Library upgrader? It is installed in Applications > Utilities. Launch it and direct it to your iPhoto library.
    Which version of iPhoto did you upgrade from?
    The upgrader is only necessary, if you have been  running iPhoto7.1.2 or earlier.

  • My MacBook Pro has been running slow since I upgraded to OS X Yosemite. Any solutions?

    I have a MacBook Pro Processor 2.5 Intel Core i5. Memory 4GB. Since I have upgraded to OS X Yosemite it has been running extremely slow. Any solutions to getting it back up to speed?

    If you enabled FileVault when you upgraded, it will take a few hours for the conversion process to finish, and during that time performance will be reduced. Otherwise see below.
    Launch the Console 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 Console in the icon grid.
    The title of the Console window should be All Messages. If it isn't, select
              SYSTEM LOG QUERIES ▹ All Messages
    from the log list on the left. If you don't see that list, select
              View ▹ Show Log List
    from the menu bar at the top of the screen. Click the Clear Display icon in the toolbar. Then take one of the actions that you're having trouble with. Select any messages that appear in the Console window. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message by pressing command-V.

  • MBP Early '11 nearly unusuable after upgrade to OS X Yosemite

    I am having problems with my mac getting even close to the boot times it had before upgrading to OS X Yosemite. It also is having problems with disconnecting from the wifi and always has problems loading up programs, folders, and etc.

    You haven't enough memory for all the junk you are trying to run concurrently. I suggest you clean up the act. The following applies to Mavericks and Yosemite.
    A. Install or Reinstall Lion/Mountain Lion from Scratch
    Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
    Boot to the Recovery HD:
    Restart the computer and after the chime press and hold down the COMMAND and R keys until the 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.
    Erase the hard drive:
      1. Select Disk Utility from the main menu and click on the Continue button.
      2. After DU loads select your startup volume (usually Macintosh HD) from the
          left side list. Click on the Erase tab in the DU main window.
      3. Set the format type to Mac OS Extended (Journaled.) Optionally, click on
            the Security button and set the Zero Data option to one-pass. Click on
          the Erase button and wait until the process has completed.
      4. Quit DU and return to the main menu.
    Reinstall Lion: Select Reinstall Lion/Mountain Lion and click on the Install button.
    Note: You will need an active Internet connection. I suggest using Ethernet if possible
                because it is three times faster than wireless.
    B. Install Mavericks, Lion/Mountain Lion Using Internet Recovery
    Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
    Boot to the Internet Recovery HD:
    Restart the computer and after the chime press and hold down the COMMAND-OPTION- R keys until a globe appears on the screen. Wait patiently - 15-20 minutes - until the Recovery main menu appears.
    Partition and Format the hard drive:
    Select Disk Utility from the main menu and click on the Continue button.
    After DU loads select your newly installed hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
    Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed. Quit DU and return to the main menu.
    Reinstall Lion/Mountain Lion. Mavericks: Select Reinstall Lion/Mountain Lion, Mavericks and click on the Install button. Be sure to select the correct drive to use if you have more than one.
    Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
    This should restore the version of OS X originally pre-installed on the computer.

  • I,just,upgraded,my,Mac,to,Yosemite

    I,just,upgraded,my,Mac,to,Yosemite,and,now,get,a,gray/white,screen,with,no,Apple ,logo.,,Doesn't,completely,restart.,,Tried,holding,"Option",and,"Command,R",whil e,restarting,with,no,change.,,Have,a,bootable,drive,hooked,up,,too.,,Please,help !?
    <Edited by Host>

    Take each of these steps that you haven't already tried. Stop when the problem is resolved.
    To restart an unresponsive computer, press and hold the power button for a few seconds until the power shuts off, then release, wait a few more seconds, and press it again briefly.
    Step 1
    The first step in dealing with a startup failure is to secure the data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since the last backup, you can skip this step.
    There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
    a. Start up from the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.” The article refers to starting up from a DVD, but the procedure in Recovery mode is the same. You don't need a DVD if you're running OS X 10.7 or later.
    b. If Step 1a fails because of disk errors, and no other Mac is available, then you may be able to salvage some of your files by copying them in the Finder. If you already have an external drive with OS X installed, start up from it. Otherwise, if you have Internet access, follow the instructions on this page to prepare the external drive and install OS X on it. You'll use the Recovery installer, rather than downloading it from the App Store.
    c. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
    d. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
    Step 2
    If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use the technique in Step 1b, 1c, or 1d to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
    Step 3
    Sometimes a startup failure can be resolved by resetting the NVRAM.
    Step 4
    If a desktop Mac hangs at a plain gray screen with a movable cursor, the keyboard may not be recognized. Press and hold the button on the side of an Apple wireless keyboard to make it discoverable. If need be, replace or recharge the batteries. If you're using a USB keyboard connected to a hub, connect it to a built-in port.
    Step 5
    If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
    Step 6
    Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to start up, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can start up now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
    Step 7
    If you've started from an external storage device, make sure that the internal startup volume is selected in the Startup Disk pane of System Preferences.
    Start up in safe mode. Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Post for further instructions.
    Safe mode is much slower to start and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
    The login screen appears even if you usually log in automatically. You must know the login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
    When you start up in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, the startup volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 11. If you ever have another problem with the drive, replace it immediately.
    If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then restart as usual (i.e., not in safe mode.)
    If the startup process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
    Step 8
    Launch Disk Utility in Recovery mode (see Step 1.) Select the startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
    This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then restart as usual.
    Step 9
    If the startup device is an aftermarket SSD, it may need a firmware update and/or a forced "garbage collection." Instructions for doing this with a Crucial-branded SSD were posted here. Some of those instructions may apply to other brands of SSD, but you should check with the vendor's tech support.  
    Step 10
    Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
    Step 11
    Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
    Step 12
    This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a startup failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
    Step 13
    If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

  • Yosemite slow on Macbook Air

    Help! Seriously....
    I updated to Yosemite the other day and since then my Macbook is extremely slow...
    It is really annoying, especially because I have no clue what the reason could be.
    I would really appreciate if anyone has an idea how to fix this.
    Apple doesn´t seem to know the answer! (What a let down...)
    Thank you very much for taking your time!
    Some of the problems:
    + The fan is running much more often now
    + MacBook gets very warm
    + Battery drain is extremely high
    + Animations and scrolling inside OS not fluent anymore
    I have already tried the following:
    + new install
    + verify disk permissions
    + SMC-Reset
    + PRAM Reset (Cmd+P+R)
    Here comes my report, I really hope anyone can help me with that.
    I am really disappointed of Apple... What a let down!

    Had the same problem, finally realized that the FileVault Encryption was struck at 19%. Speed back up to normal after I disabled FileVault using terminal command - sudo fdesetup diable
    To check whether the FileVault is the culprit, go to System Preferences --> Security & Privacy --> FileVault to see if encryption is in progress.. For me the blue bar was less than a quarter with status 'estimating time remaining'..
    Then open Terminal and type in: sudo fdesetup disable
    It will then ask for the admin password (to be it asked twice), then it was disabled... Back to normal life again..
    Here is my terminal log for reference:
    Last login: Tue Oct 21 23:05:13 on console
    Gowthams-MBP:~ asgowtham$ fdesetup status
    FileVault is On.

  • OS Yosemite Slowed My MAC DOWN!

    I am new to Mac and a brand new user with Apple products.  Since I upgraded to this OS Yosemite, it slowed my computer even slower than my previous windows pc.  As a new user, I am very disappointed and of course I can't return my Mac now since its over the 14 days from Best Buy!  Will apple fix this slow rebooting/booting issue in the very near future?  Will an Apple specialist let me know if I am stuck with this expensive version of computing as if I never left PC Windows.   I am pretty upset right now!

  • Since upgrading from Mavericks to Yosemite Mail, Spotlight,Mission Control and App-Store don´t work correctly. Is it possible to return to Mavericks?

    Since upgrading from Mavericks to Yosemite Mail, Spotlight, Mission Control and App-Store don´t work correctly. Is it possible to return to Mavericks?

    If you have an external drive with an OS X Time Machine backup, then do restore of your last backup. If you have an external drive  with a bootable clone of your previous system, you can boot to that clone and re-clone the OS X on your external drive back to your Mac's internal drive.
    If you do not have either of these available, then the reverting/restoring process becomes much more complicated and involves purchasing an external drive and backing up your current system to that drive, then erasing, reformatting your hard drive and now your only options to installng an OS X version is doing a clean install of OS X 10.6 Snow Leopard, then upgrading, again, to either OS X 10.7 Lion or 10.8 Mountain Lion. OS X 10.9 Mavericks is no longer available for download and Apple has not made OS X 10.9 Mavericks available in any other form to be able to redownload and install.
    Maybe it would be better to explain in detail your issues with Yosemite to see if any of us here can help you with your difficulties.
    I am not running or using Yosemite, so I cannot help you with your Yosemite issues,
    There are others here who can help you with Yosemite.
    Good Luck.

  • May I face any problem (like lagging) after upgrading to OS X Yosemite?

    I have a macbook pro 13 inch retina display (Core i5, Ram: 4GB, 128 GB SSD etc). Is that configuration okay for the upgrade? or may I face any kind of problem (lagging in performance etc) in future?
    thanks!

    I have a 2011 MacBook Pro and with Yosemite the machine runs faster.  The memory usage algorithm is significantly better so the memory pressure is about half of what it was under Mavericks.
    If you install, first thing to do is then open Disk Utility and Repair Permissions then restart.  They seem to be messy  after the install.

  • Illustrator CS5 issues after upgrading to OS X Yosemite

    Hi, I upgraded to OS X Yosemite recently and since then
    my Illustrator CS5 has started playing up.  A few days ago I noticed it
    was taking a long time to save and now it won't let me export files to jpeg
    format. It crashes. Please help!

    Adobe has a forum. I'd look there to see if others are having issues.
    It is entirely possible that CS5 isn't fully compatible with Yosemite. Adobe's preferences is to push/support their subscription Creative Cloud, and making older software work is kinda counter to that. (and honestly I couldn't install CS2 on my windows 8 machine, the minimum compatibility was CS3 for Windows 8, so it's not unknown for Adobe programs to have a limited backwards compatibility)

    I would like to upgrade to OS X Yosemite because my mac is outdated and slow.
    1. How do I get this upgrade? Can I buy snow leopard then download OS X Yosemite once I've downloaded snow leopard?
    2. When I upgrade, will I lose all my files or will the files and software transfer to the new OS X?
    3. Do I have enough space for this upgrade?
    4. Once updating, will it make my mac faster?
    Thanks.

    Yes, you can.
    Upgrading to Snow Leopard
    You can purchase Snow Leopard through the Apple Store: Mac OS X 10.6 Snow Leopard - Apple Store (U.S.). The price is $19.99 plus tax. You will be sent physical media by mail after placing your order.
    After you install Snow Leopard you will have to download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8 and give you access to the App Store. Access to the App Store enables you to download Mavericks if your computer meets the requirements.
         Snow Leopard General Requirements
           1. Mac computer with an Intel processor
           2. 1GB of memory
           3. 5GB of available disk space
           4. DVD drive for installation
           5. Some features require a compatible Internet service provider;
               fees may apply.
           6. Some features require Apple’s iCloud services; fees and
               terms apply.
    Upgrading to Yosemite
    You can upgrade to Yosemite from Lion or directly from Snow Leopard. Yosemite can be downloaded from the Mac App Store for FREE.
    Upgrading to Yosemite
    To upgrade to Yosemite you must have Snow Leopard 10.6.8 or Lion installed. Download Yosemite from the App Store. Sign in using your Apple ID. Yosemite is free. The file is quite large, over 5 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.
