Slow boot after updating to 10.7.2

Hi there,
Since updating from SL to Lion, I have noticed a slower boot up than usual, but now even more so since updating to 10.7.2. Furthermore once it is at the login screen, it fails to find the bluetooth magic mouse meaning I have to switch it off and on for it to be recognized. Once the mouse connects, there are no further issues with bluetooth.
Is there a way for me to check what is being used during startup, or some way to edit the startup process?
Mac is a 24" 2008 model, Core 2 Extreme with 4GB RAM.

Hello:
I don't know about the "slow," but try this for the mouse problem:
Trash a preference file (com.apple.bluetooth.plist) and restart.
Reset the PRAM and SMC
Make the mouse a favorite

  • Mac won't boot after updating to OSX 10.6.4

    I am on my 3rd Mac that won't boot after updating to OSX 10.6.4. One MacBook Pro and two iMacs. I fixed one but the last two are getting the better of me. HD is not fried. Have tried every keyboard shortcut on startup, Disk Warrior via. Target Disk, repairing permissions in single user mode. The machines will not boot off of a CD or DVD and it will not boot up in safe mode. Something in the startup files is preventing startup. I am suspecting Sophos antivirus. I tried to uninstall it and trash it but I think it's still blocking something. Any help would be appreciated.

    Got it! Not sure if removing Sophos had anything to do with it but here's what I did.
    1) boot dead machine in Target Disk Mode (iMac)
    2) boot good machine off Snow Leopard disk (MacBook)
    3) install OS to dead machine- I found this next part very curious. When the install was complete the MacBook restarted as the iMac.
    4) ran software updates
    5) shut down MacBook then shut down iMac
    6) rebooted iMac- all was good
    I actually did this twice because a co-worker had the exact same problem on her MacBook Pro. Got both fixed today.
    Thanks everyone for your help!

  • Very slow boot after installing 10.10.3

    insanely slow boot after installing 10.10.3, it takes 10times longer compare to 10.10.2, using MBA 2014

    Open System Preferences, select Startup Disk, and make sure your internal drive is selected as the startup disk. Then click restart!
    This worked for me, personally with the same issue.
    Good luck!

  • Slow Boot after 10.4.3 Update

    Hi,
    I'm experiencing a really slow boot time after updating to 10.4.3.
    This only effects my Dual 2.3 G5, the iMac G5 boots as normal.
    It seems to hang for at least 2 minutes on the grey screen before completing the boot and launching the login window.
    I booted in verbose mode <apple> V , to see where it seems to be hanging and this is what is on screen at the time:

    Nov 23 16:07:04 localhost kernel[0]: UniNEnet: Ethernet address 00:11:24:86:33:46
    Then after almost 2 minutes it moves on with the rest:

    Hi,
    I have the same problem. My iMac also hangs for about one minute at the same place;
    "Nov 23 16:07:04 localhost kernel[0]: IPv6 packet filtering initialized, default to accept, logging disabled

    but with a different MAC address ofcourse.
    I 've run the maintenance scripts and repaired permissions using Onyx but it did no difference.
    Any other ideas?

  • Mac Mini won't boot after update

    I have a Mac Mini that won't boot after the most recent software update. Since the Mini has only a bluetooth keyboard and mouse, a number of the usual options (hold down shift, etc.) won't work. I've tried a reset, also no luck. At the moment, I can't locate my Tiger install CD either.
    When holding the power button on during boot, I get a series of flashes from the status light on the front (a set of very rapid flashes, followed by a slower set, followed by a slow set) but no startup chime, or fan, or video. My display and power source are both known-good (work fine with my Powerbook)
    Any suggestions, other than buying a hardwired keyboard/mouse?

    Welcome to Apple Discussions!
    The 'newer version of OS X" error occurs because the installer on the DVD you have booted to has by default been set to update the version of MacOS on the hard drive, which of course it can't do because the version of MacOS it is installing is newer. The only way to install in this situation is to select a different option. However, that isn't what you want to do at this point, because as it says, you'll loose your data if you do an 'erase and install'.
    Instead, you should see menus at the top of the screen when it's booted to that install disk. Click the Utilities menu, select Disk Utility, and then click the top entry for the internal hard drive on the left. Once done, click on the 'Repair Disk' button (not Repair Permissions). This will test the drive to make sure it's OK. If it reports errors, and then reports 'error or exit' with the drive not repaired, you will either need a 3rd party application such as Alsoft's Disk Warrior, or to perform an erase and install (which of course you don't want to do at this point because your data is not backed up).
    If the Repair Disk process completes with no errors, next select Repair Permissions, and let that process complete, then reboot the system as normal to see if you can now access the drive.

  • Slow computer after update to 10.7.4.

    After updating to 10.7.4., my MacBook Air (2,13 Ghz Intel Core 2 Duo, 2 GB 1067Mhz) my became very sluggish. Logging in lasts 5 minutes, all programmes are very slow, internet is slower, even typing is something difficult. Do you have any suggestions to remedy this situation ?

    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.
    ☞ If you’re running Mac OS X 10.7 or later, open LaunchPad. Click Utilities, then Console in the page that opens.
    Step 1
    Select "system.log" from the file list. Enter "BOOT_TIME" (without the quotes) in the search box. Note the timestamps of those log messages, which refer to the times when the system was booted. Now clear the search box and scroll back in the log to the last boot time when you had the problem. Post the messages logged during the time something abnormal was happening. That time might be before or after the boot.
    For example, if the problem is a slow startup taking three minutes, post the messages timestamped within three minutes after the boot time, not before. If the problem is a system crash or freeze, post the messages from before the boot time, when the system was about to crash or was failing to shut down. In either case, please include the BOOT_TIME message at the beginning or the end of the log extract.
    Post the log text, please, not a screenshot. If there are runs of repeated messages, post only one example of each. Don’t post many repetitions of the same message.
    If the log doesn't go back far enough in time, scroll down in the Console file list to /private/var/log/system.log.0.bz2. Search that archived log, and if necessary the older ones below it, for the same information.
    Important: Some private information, such as your name, may appear in the log. Edit it out by search-and-replace in a text editor before posting.
    Step 2
    Do the same with kernel.log.
    Step 3
    Still in Console, look under System Diagnostic Reports for crash or panic logs, and post the most recent one, if any. In the interest of privacy, I suggest you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if present (it may not be.) Please don’t post shutdownStall or hang logs — they're very long and not helpful.

  • My MBP doesnt boot after update / Prohibition sign flashes twice and then goes straight to OX Utilities

    Hello all,
    I thought I would never be here, but I am.
    After updating iTunes and Memory Clean in App Store (nothing unusual) my MAC stopped booting properly.
    MBP / early 2011 / Mountain Lion
    It shows the Apple logo flashing twice the prohibiting sign (cancel circle), after that it goes straight to the OS X Utilities.
    Note:
    - It recognizes the HD and the Recovery partition.
    - Verify permission shows a lot of /Applications/iTunes issues, but I have repaired like 5 times and still showing issues.
    - Hardware test passed OK.
    - Repair disk, no issues.
    - Shift (safe mode) doesn't work (lot of flashing ? folder, apple logo, etc).
    - PRAM restarted, twice.
    I can't reinstall or launch the ML installer, when I go trough the install process which mandatory requires Internet connection and AppStore login, it states: This item is temporarily unavailable. Try again later.
    Please help me, I'm desperate this is my production machine and I'm travelling.
    What I'm missing?

    You cannot reinstall Mountain Lion from the App Store, but you can install Mavericks which is free and will run on your computer. Here's what you do:
    Install or Reinstall Mavericks or 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.
    OS X Mavericks- Erase and reinstall OS X
    OS X Mountain Lion- Erase and reinstall OS X
    OS X Lion- Erase and reinstall Mac OS X
    Note: You will need an active Internet connection. I suggest using Ethernet if possible
                because it is three times faster than wireless.

  • Macbook pro won't boot after update to 10.6.8

    Hi everyone,
    Yesterday I bought an used macbook pro (15 inch early 2008). When looking at it, it was in good shape and the previous owner just did a fresh install of snow leopard. I took it home and whas happy with it. In the first two hours of using it, everything was fine. After installing the update to 10.6.8 my macbook needed to be shut down.. After shutting down it started up again but the screen stayed black. I had no idea why. So I rebooted it by pressing the power button. The same problem remained, it seemed to start up (I could hear the harddrive and fan) but it didn't boot into Mac Os. After a couple of attempts, it now shutsdown immediatly after pressing the powerbutton (3 seconds after). No chime or nothing.
    At first I thought this would only be a software problem, because the problem started immediatly after updating. So I put in my snow leopard dvd to boot into that, but I can't even get it to boot into the install dvd. Because it shuts down immediatly after pressing the power button. Then I started suspecting an hardware failure, which would be a very big coincidence to show up immediatly after booting up. These are the things I have tried so far, to no avail:
    - Plugging of the power cord and removing the battery, then pressing and holding the powerbutton for at least 5 sec
    - Holding the option, command, P and R keys during boot.
    - Replacing the memory
    - Replacing the hard drive
    - Unplugging the super drive
    - Starting up holding the d key
    At a certain point I was hoping that It would be an harddrive or memory problem. I replaced both with examples I know for sure they are working. But still the same problem; macbook shuts down  almostimmedialty after pressing the power button.
    There is no warrany anymore, and technical support would cost me 49 euros per incident.. to probably hear that the macbook is beyond repair. I feel i have just thrown away 300 euro's for an nightmare experience. Does anybody now anything to try, i'm really desperate here

    After installing the update to 10.6.8
    What update was that?
    So I put in my snow leopard dvd to boot into that, but I can't even get it to boot into the install dvd.
    Did the previous owner also give you the discs that originally came with the computer?  Those are what you need to troubleshoot with.  You also need disc 1 to run the Apple Hardware Test.
    There is no warrany anymore, and technical support would cost me 49 euros per incident..
    Apple Store and AASP diagnostic testings are free.  Suggest that you take full advantage of it.  This way you can find out exactly what is wrong with your computer.  Post back here with the diagnosis and someone will post DIY repair sites.

  • MBP retina slow booting after repartitioning and cloning OS X

    I bought a Macbook Pro retina 15" (512/16GB) few days back. OS : Mountain Lion 10.8.4
    I wanted to partition the SSD to have Windows 7 in Boor Camp (120 GB), then a partition with ExFAT (260 GB) for shared data between Mac and Windows and lastly Mac HD (120 GB) with Mountain Lion OS X.
    After searching in the net, I got this link :http://forums.macworld.com/index.php?/topic/139815-successful-setup-os-x-lion-bo otcamp-win7-data-partition/page__st__14 and followed the steps as described the steps in pane # 21.
    So to state again what I did,
    1. Used the disk utility to resize the Macintosh HD to 120 GB.
    2. Make another partition of 260 GB in the remaining space. So I now have three partition, the first with Mountain Lion, the second (260 Gb) and the third (120 GB) free.
    3. Booting with the recovery option, cloned the Mac HD from first partition to the last partition.
    4. The system was booting fine with the newly cloned Mac HD (last partition).
    5. Then again booting with the recovery option erased the first partition and formatted with ExFat to make it Bootcamp.
    After these steps the system is booting fine with the cloned Mac HD bootable drive but booting is very slow. It takes a minute to show up the apple logo. How can I fix this ?
    Should I do a fresh installation of OS X in partition 3 ? Please advise.
    Thanks and best regards,

    I solved the problem of slow booting.
    Selecting the Mac HD from the start up disk option solved the problem. There was only one option : Mac HD , so I thought it is selected by default. But after selecting it manually and restarting, now boot takes only a few secs. Thanks.

  • IMac 24" Intel Core 2 black display on boot after update to 10.6.7

    Help!
    After updating software to 10.6.7, my iMac won't display anything but a black screen after booting, the system seems to be working because you can figure out that the list of users is there to start up (keyboard & sounds) but no display. Things I have already tried: Reset PRAM and SMC and nothing. It's black.
    I will appreciate any kind of help.
    Thanks to all

    I'm having the same problem. I took my iMac to a genius bar and they couldn't help. Apple needs to address this.

  • Mac Mini 2011 slow down after updating to Yosemite

    Hi all!
    After updating my Mac Mini (half 2011) from Mavericks to Yosemite, it became extremely slow and unresponsive. I have to wait a lot of time for apps to open and commands, like clicking a button, to be executed executed. File Vault, that I read is a common cause of slow down, is NOT enabled.
    What should I do? In these cases, for my Windows PC, I insert the OS DVD and format: what's the equivalent operation for a Mac?
    Thank you in advance for your help!

  • Flame won't boot after update (1.4)

    Hello,
    I was running nightly FFOS 1.4 on my Flame for last month.
    Today, after update and reboot, phone boots into recovery mode.
    It looks like fastboot (I can see only ThunderSoft(r) logo) but I can't see phone listed with fastboot command.
    It does, however, respond through adb.
    Commands like adb shell are not limited.
    What should I do now? I rather ask for help now, since I have already broken my zte -.-
    This time I didn't do anything strange to it so.. Will be glad for any response. Thank you

    fastboot mode: power button + volume-down button for 10 ~ 20 seconds
    recovery mode: power button + volume-up button for 10 ~ 20 seconds
    firmware update is much easier in linux rather than windows.
    flame phone should be in unplugged and power-off state.

  • Slow editor after update

    Is it my imagination, or has there been a performance hit after update 1? After heavy use, I've had to restart eclipse in order to speed things up, which seems to help for a short time, but eventually the editor slows down again, particularly on large CFC files with a mix of CF and HTML code. Sometimes I have to wait a couple seconds after each editor change before I can do anything, which is problematic when you're trying to move quickly. That's when I just restart and say F###! Everytime this happens, the little tractor track progress icon moves. Not sure what it's doing since it goes away too quick for me to click on it. Could it have something to do with syntax highlighting? I notice that the screen flickers a lot after each editor change, which is also annoying.
    I can't wait until CFB becomes a stable and fast because it's DEFINITELY NOT!

    I think I've resolved my performance issues by increasing the memory size of eclipse... I modified the eclipse.ini file from:
    -startup
    plugins/org.eclipse.equinox.launcher_1.0.201.R35x_v20090715.jar
    --launcher.library
    plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.0.200.v20090519
    -showsplash
    org.eclipse.platform
    --launcher.XXMaxPermSize
    256m
    -vmargs
    -Xms40m
    -Xmx256m
    to:
    -startup
    plugins/org.eclipse.equinox.launcher_1.0.201.R35x_v20090715.jar
    --launcher.library
    plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.0.200.v20090519
    -showsplash
    org.eclipse.platform
    --launcher.XXMaxPermSize
    256m
    -vmargs
    -Xms128m
    -Xmx512m
    (changed: -Xms40m to -Xms128m and -Xmx256m to -Xmx512m)
    So far the performance has been acceptable. I've been using these settings for about a week or so, and so far I haven't had any serious performance issues.

  • Not able to boot after updating to 10.5.1

    Hi all,
    Have been running 10.5 on an external disk having left Tiger on the internal.
    After updating to 10.5.1 the system doesn't boot at all. I get the grey screen with the apple symbol and NO spinning "wheel". I have to re-boot from the install DVD to be able to change the start volume to 10.4.11. From Tiger I have tried to change the start-up volume to 10.5.1 again but still the same problem, in some cases it goes back and starts Tiger even if I set the volume to Leopard.
    Re-installing 10.5 doesn't change anything, the older version behaves in the same way.
    I suspect it must have something to do with booting sequence.
    Any suggestions ?????

    If you're comfortable with opening things up you could take the drive out of its case and plug it into the ide cable inside the G4 along with your existing system drive. (Assuming this is a G4 tower)
    To be on the safe side you could just swap it with your current internal disk and see if it boots as well.

  • AirPort very, very slow & intermittant after update

    I installed the AirPort Extreme Update 2007-001 from today's Software Update, and on restarting, my wireless connection became extremely slow (56k speeds at best) and very intermittant -- it'll work for a minute or so, then lag for two or three minutes with no signal. I've rebooted several times, but it hasn't helped.
    Is anyone else having trouble after the update?
    MacBook Pro, 15"   Mac OS X (10.4.8)  

    The "solution" is at http://www.macfixit.com/
    Problems after updating
    [In many cases, the problems listed below are incidental to the update and can be solved by some of the workarounds listed in our wireless troubleshooting tutorial -- many users have reported success with turning off wireless encryption (WEP, WPA) on their Base stations, for instance.
    If you are having extreme difficulties after applying this update, the workarounds listed in our wireless tutorial have failed, and you absolutely need to restore wireless access, you can try this somewhat risky workaround:
    Download the most recent version of Mac OS X for Intel (10.4.8)
    (http://wsidecar.apple.com/cgi-bin/nph-reg3rdpty2.pl/product=11796&cat=1&platform =osx&method=sa/MacOSXUpd10.4.8Intel.dmg)
    but do not install it.
    Download and install the shareware application Pacifist
    Drag the Mac OS X 10.4.8 installer package onto the Pacifist application icon.
    Click the triangle next to "System" to expand it
    Click the triangle next to "Library" to expand it
    Click the triangle next to "Extensions" to expand it
    Scroll down and find the file IO80211Family.kext. Drag it to your Desktop or another location (you will have to enter your administrator password)
    On your Mac OS X startup drive, navigate to /System/Library/Extensions and locate a similarly named file (IO80211Family.kext). Move it to another location for safe keeping.
    Now drag the file from step 7 (the one that you retrieved from the Mac OS X 10.4.8 install package) into the /System/Library/Extensions, in effect replacing the newer file (installed by the AirPort updater) with and older copy -- you will have to enter an administrator password.
    Restart your Mac
    This workaround is risky because you should not generally mix and match kernel extensions after updates, you will lose some improvements (including security refinements) brought about by AirPort Extreme Updater 2007-001, and new conflicts can ensue. Still, in a bind, it can restore wireless connectivity where other workarounds fail.]
