Sluggish and Jerky scrolling on Macbook Pro (Retina)

The Problem
Over the past few months or perhaps longer, I have noticed poor performance with scrolling and responsiveness of my Mac when browsing the web and performing normal functions. It was often sluggish or jerky.  At its worst, it was like watching a slide show when scrolling. The problem mostly represented itself when using web browsers, and worst of all in Google Chrome.  No application was completely immune, but some performed better than others.  Sounds like a Software issue right ?  I had attempted small and drastic things to try to solve the issue.   After I completely re-formatted and re-installed Mavericks on my Mac, and the problem persisted. Ugh... Contacted support, and they ran me through the usual PRAM reset and reboot stuff, but no real solution was found.
I finally found an obsecure document that suggested that it may actually be a hardware issue.
I determined that the issue was not due to poor performance of the OS, Software or general CPU/MEM utilization as I had been assuming for months.  After some extensive troubleshooting I determined that the Trackpad was in fact the issue.   Through recording Trackpad coordinates and troubleshooting the scrolling process, it was apparent that "when scrolling" the Trackpad was sending "sluggish/jerky" data to the OS.
The Fix
After I found this, It was simple to find a lesser-known fix for the Mac which consists of Resetting the SMC.  The SMC is the controller for the Low-Level hardware (Trackpad included).  It is the general interface between much of the hardware in your Operating System.  How it was "corrupted" or made to perform badly is anyone's guess.
I ended up resetting the System Management Controller (SMC) which made a drastic difference for the better.
Process for resetting the SMC:
For the MacBook Pro Retina Laptop (Non-removeable Battery)
Shutdown your Mac, ensuring that you Power it off completely.
Connect the Power Cord if not already connected.
On the Built-in Keyboard (Left Side) Press the Following Sequence:CONTROL-SHIFT-OPTION   once pressed, Press and Hold the POWER button (Hold for several seconds)
Release the keys at the same time.
Repeat (if you want,  I did)
Then Press the Power Button to restart the computer.
Hopefully Enjoy smooth scrolling and TrackPad movement.
To reset the SMC on other Mac Models,  Refer to the Apple Support Doc: http://support.apple.com/kb/ht3964
It Works Mostly
I still find that on occasion the issue re-surfaces for a short time, and is generally assiciated with high utilization of CPU.  But in all,  it's like having my brand new Mac back.
NOTE:  Please be sure that you troubleshoot and determine that this is the most likely issue.  Resetting the SMC is a LOW-RISK process, but Apple recommends that you only do it if absolutely necessary.
I Hope this helps someone else out.   After the countless hours of troubleshooting I have done on this, and in finding the ultimate solution,  I felt compelled to write it up on the forums for others to find.   Enjoy.

PRAM contains settings for a number of things. Resetting it cannot hurt and "might" fix the problem. As I indicated, if that does not help, take it in for service.

  • Keyboard Cover and Hard Case on Macbook Pro Retina

    I have just heard that Apple suggests to remove palm rest protector on Macbook Pro Retina.
    Reference: http://support.apple.com/kb/TS4384
    Now, my question is:
    Is it ok to put keyboard cover and hard case on Macbook Pro Retina? Or will it affect the product just like the palm rest protector?
    Thanks

    Thanks for your reply.
    The keyboard protector that I got is Moshi's. They said it's extremely thin, will it be still a problem? Because as I compared with the palm rest protector, it's much thinner.
    Here is the link for reference: http://store.apple.com/us/product/TV901LL/A/moshi-clearguard-keyboard-protector- for-aluminum-macbook-and-macbook-pro
    And, the hard case that I mean is something like Kuzy sold in Amazon (http://www.amazon.com/Kuzy-Crystal-15-4-Inch-MacBook-Display/dp/B008B09LRY/ref=s r_1_4?ie=UTF8&qid=1350354859&sr=8-4&keywords=kuzy+macbook+pro+retina)
    Any further opinion on this issue?
    Thanks.

  • Poor battery life and high temperatures on MacBook Pro Retina 15"

    I'm having never-ending problems with poor battery life and high temperatures on a MacBook Pro Retina 15"
    I took it in for service and they told me it needed a new logic board and replaced it.  When I asked why they were vague about the reasons, they said "it just needed one, it failed some test".  I now have the computer back and it runs the same way it always did.  I bought this laptop because it was supposedly capable of high end video editing in 1080P (or so Apple's website claims) and also photo editing. 
    "The processor, graphics, all-flash architecture, memory, and display in the 15-inch MacBook Pro give you unprecedented mobile video editing capabilities. Super-responsive flash storage delivers up to nine streams of 1080p ProRes (HQ) content for multicam editing in Final Cut Pro X,3 while the latest quad-core processors on the 15-inch MacBook Pro decode multiple streams of video, and a powerful GPU renders millions of pixels onto the screen. With flash storage that offers up to four times the performance of a traditional hard drive,1 you can even edit four streams of uncompressed 8-bit 1080p HD video, right from the internal storage on your 15-inch MacBook Pro with Retina display.4"
    However, when I'm just browsing the web and emailing it runs quite warm and battery life is quite poor.  Sometimes doing those same activities I would say it gets so warm it's almost uncomfortable to have on your lap and the fans are running fast enough to become noticably noisy.  I'm also driving only one screen at and a time and I heard that the MacBook Pro can supposedly do three screens.
    If actually try to do something like video editing with final cut pro the laptop gets really hot, the fans are on full blast and battery life drops to only an hour or two.  I think when I rendered just a 3 or 4 minute clip once I got less than hour of battery life.  I will have to time again.
    Anyway most people (including the sales guys) are telling me no way this is not normal.  When I play with demos in the store browsing the web they are not getting warm or hot to the touch.  My friend's 2013 MacBook Air is also NOT getting warm to the touch doing the same activities.
    I installed iStat Pro so I could check the temperature and fan speeds.  I'm seeing temperatures of 70+ on the GPU, 85+ on the GPU diode and 65+ on the CPU heatsink along with elvated fan speeds above 5K which becomes noticeably noisy.  I understand that might be normal for the most processor intensive tasks but it really doesn't seem right for just light web browsing and e-mailing.  (I also may have viber and skype open but that shouldn't matter).  CPU usage is usually running between 2-10% as this is all happening to.
    Furthermore, straight from the specs:
    Intel HD Graphics 4000
    NVIDIA GeForce GT 650M with 1GB of GDDR5 memory and  automatic graphics switching
    I am assume "GPU" and "GPU diode" are temp measurements on the discrenete NVIDIA video card, especially since MacBook Airs from the same and newer generatio do not have this reading.  Since Apple Claims the graphics "automatically switches" it seems all the harder to believe the GPU is reaching 85+ when in theory it shouldn't even be activated.  I mean, shouldn't the INtel HD Graphics 4000 be capable of simple web browsing and e-mailing?  Especially with only one screen activated (be it it the internal or an external)?
    What should I do here?  When I asked the repair guys "OK well what is the normal operating temp range for the various sensors" they said "Sorry Apple doesn't provide that info". 

    Yes I have.
    Just web browsing and basically doing nothing I'm hear a lot of aduible fans, I'm getting 85C+ on GPU diode, 65+ on cpu heatsink.  I since installed anohter program that shows me not just the CPU heatsink but the cores and the cores are at 90C+.
    Seems like a lot of heat for doing nothing.  Not only that but I have these problems with no external monitor while on battery power too.
    I don't know what to do.  They already replaced the logic board.  Others seem to get advertised battery life out of Apple products and not have products that get **** near hot enough to burn you while just web browsing or watching a movie let alone advertised tasks like Photoshop and Final Cut Pro.

  • RAM issue on Mavericks 10.9.3 and 2013, 13 inch macbook pro retina.

    I have a 2013 macbook pro retina. Intel I5, 8gb RAM, 250gb SSD. Now I am a student and don't throw very intensive programs at it. Just the basic stuff. And a few casual games here and there. SO my problem is I don't understand why swap has been enabled (although only a bit) and so much of my 8GB RAM is always being used. I thought that Mavericks was supposed to be more efficient in terms of memory. If anyone can help/explain this to me it would be greatly appreciated.

    Mavericks is designed to use all available RAM, allocating as you go along. See http://www.apple.com/osx/advanced-technologies/ for details.

  • Mac os x yosemite 10.10.1 still lags and bugs while using macbook pro retina 13inch i5 mid 2014

    i just got macbook pro retina and i upgraded to yosemite 10.10.1 its still have bugs and lags a lot , does anybody feel the same ,
    its not smooth at all ..

    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.
    4. Reinstall Yosemite: Reboot from the Recovery HD. Select Reinstall OS X 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.
    5. Reinstall Yosemite 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.
    How to Clean Install OS X Yosemite
    Note: You will need an active Internet connection. I suggest using Ethernet if possible

  • IMac and iPad air vs MacBook Pro retina

    Hello there
    With the new products being released, I was wondering what combination people have gone for.
    At present I have an iPhone 5s, iPad 2 and windows laptop but really want a mac.
    What combination have others gone for??
    I am considering iMac and iPad air, or Retina MacBook Pro with potential retina ipad mini.
    Problem with the iPad mini is, is there a real need with the iPhone and rMB Pro?
    Cheers
    Jonathan

    My old 17" MacBook Pro finally died, since I like a large dispaly and Apple no longer makes a 17" laptop I decide on a 27" iMac. I travel quite a bit and since my iPad 3 has replaced the laptop while I'm on the road I decided my money was better spent getting a higher end iMac rather than a MacBook. Even around the house my MacBook was pretty much left on the desk since I always grab the iPad when going portable.
    I wouldn't compare the iPad with an iPhone. And the only way to really choose between the iPad mini and an Air is to go to a store and hold them. Myself, I again prefer the larger screen.

  • Question on using bootcamp and windows on 15" macbook pro retina (late 2013)

    So i just bought a new macbook pro 15" retina (late 2013) and i want to play games on it like LOL, WOW, and SC2. i was wondering if i really need to play them on bootcamp using windows 7.

    Open Boot Camp Assistant (in Utilities) print out the instructions, setup Windows on its own partition, insall and run Windows natively, not much difference than on any laptop.

  • Noisy iTunes and fan problem on MacBook Pro Retina Early 2013

    Hi guys, FYI bought today my new Retina 15-inch, Early 2013, 2,7 GHz Intel Core i7, 16 GB 1600 MHz DDR3 and have the issue of sudden changes of the speed of the fans without apparent cause.
    iTunes also is unusable, all songs are noisy (like a radio transmission). Played with VLC they are fine.

    I had almost the same problem, so I tried to turn off "Automatic graphics switching" and everything is working well again. Intel integrated card is just enough if you want 8 hours of battery.

  • Average lifespan of a Macbook Pro Retina ?

    I am just wondering what would be the average lifespan of daily use , wear and tear on a Macbook Pro Retina ? I have known macs to be the most durable things on the planet. I have just purchased a referbished october 2013 13" i5 , 8GB RAM , Iris Graphics … (no nvidia option for the 13" was looking for small size mac packed with power, then limited to my money stash) , 512 GB SSD storage model to replace my 2012 i3 Lenovo laptop that has 1GB nVidia graphics 8GB RAM,500GB storage , which would be given to my parents for Christmas, because they are needing a new computer, and my late 2008 2GHz Intel Macbook, that had been upgraded to 8GB RAM, which i flashed its firmware, since the RAM was somehow maxing out at 4GB… but now uses the full 8GB, to a friend as a gift at the  art studio I work in.
    I do a variety of artwork , ranging from drawing in manga studio to photoshop and some 3D manipulation, modelling and rendering, creating music, to editing film, which may include rendering 3D character animations. I am wondering if I am going to max out this little beast, or it would follow the average lifespan of a Macbook ? Then if I consider upgrading it in the future to 16GB RAM, looks like I would have to update the entire logic board, since the RAM is soldered on, do the apple stores compensate for this option that is provide logic board upgrades ? What if they change the design of logic boards in the future ? Extra storage is not a problem, because I can always get a bigger external drive, and SD cards are becoming more capable in storing more stuff..

    Here is information on my upgrade from my previous work machine… which is a pc to the mac… as I also had/have a late 2008 macbook, which was actually good bait lol, was impressed by how it ran for an 2008 model of a computer..
    1)Lenovo Think Pad/idea pad (21/10/2011 - release date)
    £800
    Intel i3 CPU 2 cores/4 threads. 2.3 GHz
    Intel Intel® HD Graphics 3000 +
    Nvidia GeForce GT 520M
    RAM 8GB
    Storage 500 GB (normal hard drive)
    Heavy to carry with bad back from home and to the studio and back.
    New Machine:
    2)Apple Macbook Pro
    £1099
    (xx/10/2013 -release date)
    Intel i5 CPU 2 cores/4 threads. 2.6 GHz
    Intel® Iris™ Graphics 5100
    RAM 8GB
    Storage 512GB flash storage (SSD)
    lighter than late 2008 Macbook and easier to carry...
    The two old machines are still running and looked after them well, and giving them away as gifts… to those who don't have computers. I always worked with them on a desk surface, so they would not overheat when rendering still 3D artworks and animations, so it should last on average life span then...

  • MacBook Pro Retina? Or iMac?

    I'm starting online classes for my university, I will be doing online classes for two to three semesters to rack up scholarship money and then transfer to a university up here(my family just moved from NC to AK for job opportunities and I came with). I can afford either of these laptops, but I'd like not to spend a ton of money.
    I need my computer to handle gaming, web surfing, a TON of Skype(like 6+ hours of Skype a day), streaming, etc.
    I typically do a lot at the same time, an example is, I'll be on Skype, playing a game with them through Steam. I need something that can handle all of that.
    I don't want a 27" iMac because I believe that's too big and I don't need a screen that big. So I'd be deciding between the 21.5" and either of the MacBook Pro Retina models. I currently have a 13" MacBook the aluminum model and it's really hard doing all of this. I can't play certain games and Skype at the same time without the game lagging extremely bad. I do like the portable aspect of the Retina and I will eventually end up going to actually class and it would be nice to be able to bring everything with me at once. But if I get the iMac I would keep my MacBook instead of giving it to my parents and have both a desktop and a laptop. If I got the Retina I would give the MacBook to my parents to use and when my brother graduates from college in two years the MacBook would be my present to him. It's in amazing shape and would save him a ton of money!
    Any suggestions would be appreciated!
    Thank you!

    Hi, I am from Hong Kong. I have bought a customerized late-2012 iMac 27", but it hasn't been to my home yet
    For your case, you will use it for school and games mainly, but not video editing or graphic designing, right? Therefore, I suggest you for buying iMac 21.5" with high sepc one with the following reasons:
    First, you have a laptop - MacBook Pro already. Even though you said if you bought RMBP, you would give the old one to your parents, why don't you try to have a Mac desktop - iMac at home? (MacBook Pro+iMac = GREAT !!) That's my personal formula.
    Second, although Retina MacBook Pro has a awesome display, please be reminded some games may not support with such a high pixel screen. Thus, the performance may work poorly. On the other hand, for iMac 21.5", it has a 1920x1080 screen, which is suitable for most of the game. Unless you want to learn video editing, photo editing and graphic designing, I won't recommend RMBP to you.
    Last but not least, comparing the storage parts, all RMBP models use SSD for storage, but iMac use SATA or Fushion Drive only. It seems RMBP is better than iMac. However, when you consider the minimum volume of iMac, it is 1TB for both SATA or Fushion Drive, which is much greater than the RMBPs with at most 512GB SSD. As a game player, you may download several large-file games, says 2GB to 20GB. A larger volume harddisk will be better. What's more, if you choose the Apple's new technology-Fushion Drive, you will experience the efficiency of opening Apps or Games.

  • REFInd with MacBook Pro, Retina: invalid loader file!

    I'm trying to dual boot Arch and OSX on a MacBook Pro, Retina, 15".  I've been following the Direct EFI booting (rEFInd) guide, but I've also read through a lot of the related docs.  Because many instructions on the web seem outdated based on recent improvements in rEFInd, I will post what I have done so far since this info may be relevant.
    1. I resized my harddrive.  I installed arch on an ext4 formatted partition (/dev/sda4 with 128M gap before, ie.., sector "+128M" in cgdisk).
    NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
    sda 8:0 0 233.8G 0 disk
    ├─sda1 8:1 0 200M 0 part
    ├─sda2 8:2 0 116G 0 part
    ├─sda3 8:3 0 619.9M 0 part
    ├─sda4 8:4 0 17G 0 part
    └─sda5 8:5 0 99.9G 0 part
    2. Running OSX, I installed refind (refind-bin-0.8.0) using the --nodrivers option. 
    sudo ./install.sh --nodrivers
    Installation appeared to be successful. 
    3. I updated the refind.conf file.  The "scan_all_linux_kernels" is uncommented by default, and I uncommented the also_scan_dirs line so that these two lines appear as shown, with everything else default:
    scan_all_linux_kernels
    also_scan_dirs boot,ESP2:EFI/linux/kernels
    Result: rEFInd loads on boot, but no option for Arch appears (only the Mac option). 
    4. I decide to try a manual menuentry, so I set the scanfor line like this:
    scanfor internal,external,manual
    Then, I write in an entry for Arch Linux (and comment all other menu entries):
    menuentry "Arch Linux" {
    icon EFI/refind/icons/os_arch.icns
    volume 0FC63DAF-8483-4772-8E79-3D69D8477DE4
    ostype Linux
    loader /boot/vmlinuz-linux
    initrd /boot/initramfs-linux.img
    options "rw root=/dev/sda4 rootfstype=ext4 libata.force=noncq"
    I verified that vmlinuz-linux and initramfs-linux.img exist and are in the /boot directory in my main arch partition (/dev/sda4).
    Result: I get an Arch menu entry, but when I click on it I get this error message:
    Starting vmlinuz-linux
    Using load options 'rw root=/dev/sda4 rootfstype=ext4 libata.force=noncq initrd=\boot\initramfs-linux.img'
    Invalid loader file!
    Error: Not Found while loading vmlinux-linux
    I also tried these lines for volume, each in turn:
    volume 4:
    volume linuxmain
    ("linuxmain" is the partition label I gave the partition with cgdisk)
    For completeness, `diskutil list` on the Mac gives me:
    /dev/disk0
    #: TYPE NAME SIZE IDENTIFIER
    0: GUID_partition_scheme *251.0 GB disk0
    1: EFI EFI 209.7 MB disk0s1
    2: Apple_HFS Macintosh HD 124.6 GB disk0s2
    3: Apple_Boot Recovery HD 650.0 MB disk0s3
    4: 0FC63DAF-8483-4772-8E79-3D69D8477DE4 18.3 GB disk0s4
    5: 0FC63DAF-8483-4772-8E79-3D69D8477DE4 107.2 GB disk0s5
    Note that I've tried the above procedure both with the stock refind (refind-bin-0.8.0.zip) and the arch specific refind (refind-bin-gnuefi-0.8.0.zip).  In all cases I made sure all the refind files were removed before re-installing.  I've already spent a lot of time on this, and I'd really like to get Arch booting, so any help is greatly appreciated!

    I had this problem myself which got me going round in circles for ages.  The Arch Official rEFInd package contains v.0.7.9 (and is flagged out of date).  Apparently there is an Arch specific problem with v.0.7.9 and the most recent (until today) v.0.8.0.  The only way I could get it to work was to use the v.0.7.8 gnuefi binary from sourceforge.  I've been in touch with the developer who has released v.0.8.1 today which he thinks fixed the bug, but I've yet to test it....  Let us know how you get on.
    When the package gets updated I would hope for it to be built from gnuefi, not the tianocore EDK2010 as it is currently, nor even 2014 which all seems unduly burdonesome....

  • Dual 27" Thunderbolt Displays on 13" MacBook Pro Retina

    I'm thinking of buying two Thunderbolt Displays and make my 13" MacBook Pro Retina my main desktop computer. So the question is:Can the 13" MBP handle two chained Thunderbolt Displays without getting slower or will the Intel HD 4000 just melt down?
    I might wait until Apple announces the next generation of Thunderbolt Displays tho as I think this will happen soon (probably when the new Mac Pro is released?)...

    You could try changing the DPI. If you use startx, use this:
    startx -- -dpi 100
    Try experimenting with different DPI values.

  • Photoshop CS6 a little 'jerky' when moving layers & resizing window (Macbook Pro Retina 650m)

    As title says, when I open Photoshop CS6 and simple make a new layer and either use the type tool, it appears to be a little Sluggish/Jerky when moving the layer around.. The same applies when resizing photoshop itself.
    I'm updated to the latest version of CS6 and have tried all the combinations in the 'Performance' section of Photoshop.
    My Macbook Pro Retina is the 3.4ghz 650m and 8GB RAM offering (OS Mavericks). It's really annoying me as even my old laptop could run it smoothly and that was an i5 and much lower-end graphics card.
    The only way I can really describe it (and i'm no tech professional) is when comparing it to silky smooth 60 fps, it looks like it's skipping frames and in term looking 'jerky'. I also use Illustrator and don't really witness the same problem with it.
    I know this may have been asked quite a bit.. But I've never found the solution.. Could anybody advise me on what it potentially could be down too? (Might I add the laptop has just had a fresh install of the OS and a fresh copy of CS6)

    You could check through the GPU FAQ for anything you might have missed
    http://helpx.adobe.com/photoshop/kb/photoshop-cs6-gpu-faq.html
    You say you have tried all settings in Performance, but I wonder what your  cache levels are set at?  If more than 1, then OK.
    There's the general performance FAQ (no doubt lots of overlap)
    http://helpx.adobe.com/photoshop/kb/optimize-performance-photoshop-cs4-cs5.html
    Is this with all image docs, or particular ones?  For instance I have been playing with using ACR to process 32bit HDR files, and it puts a huge load on the system.

  • Macbook Pro Retina crashing when running Safari and iTunes since Mavericks

    Hello everyone.  I am starting a new thread even though there seem to be a lot of various crash reports.  I have noticed several entire system crashes (never, ever happened on my mac before until I updated to Mavericks) when using iTunes and Safari at the same time.  The entire computer crashes and/or freezes up - no keyboard or mousepad response, and no crash report, only option to manually restart by holding down power button. I include an etrecheck report below fyi, but cannot seem to locate anything myself.  I do not use external montiors or any other open apps or extensions.  OI have put this under Mavericks because this problem (as well as others I have had to fix) has only begun since updating the OS.  Apple tells me that I just have to be patient for the other software to catch up to Mavericks - but this is Apple's software!  Any ideas?  Many, many thanks, and Merry christmas.

    If you have more than one user account, these instructions must be carried out as an administrator.
    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.
    Step 1
    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.
    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 after  you had the problem. Select the messages logged before the boot, while the system was unresponsive or was failing to shut down. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message (command-V). Please include the BOOT_TIME message at the end of the log extract.
    If there are runs of repeated messages, post only one example of each. Don’t post many repetitions of the same message.
    When posting a log extract, be selective. In most cases, a few dozen lines are more than enough.
    Please do not indiscriminately dump thousands of lines from the log into this discussion.
    Important: Some private information, such as your name, may appear in the log. Anonymize before posting.
    Step 2
    Still in Console, look under System Diagnostic Reports for crash or panic logs, and post the entire contents of 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 any other kind of report — it will be very long and not helpful.
