Permissions differ after installing SSD

I recently installed a 512gb Samsung 830 series SSD into my Early 2011 13in Macbook Pro. Prior to this, I have verified disk permissions multiple times and never had any permissions differ.
Since I've installed this SSD, I've run disk permissions several times and there is usually at least a couple permissions that differ. I repair them of course, but my question is how serious could this be?
Overall, I'm happy with the performance of the drive and I haven't had any problems besides the permissions differing.
Any suggestions to fix this? And is it a serious issue? If it is, I'd like to return the drive when I still can.
Thanks for your help.

No problem, Apple has changed things in OS X and thus certain permissions will also appear to be repaired.

  • P67A-GD65 : Boot sequence keeps changing after installing SSD

    Hi,
    Before I had the SSD, all was fine and running on IDE.  After installing SSD and changing mode to AHCI, the boot sequence keeps changing after reboot.  I did not reset the CMOS after installing the SSD.  I had disabled all boot except for the SSD (which is connected to SATA Port 1).  And I did save by pressing F10 after changing the sequence in BIOS. 
    Appreciate your advise. 
    Thank you.

    I have the same problem. The board decides to try and boot from some other device, even though the SSD is detected. Very annoying.
    I'm using the sata cable that came with the board; e.g. brand new.
    system:
    P67A-GD53, bios 1.E, i5-2500K, 4x4 GB Corsair Vengeance, Corsair AX850W, OCZ Vertex LE

  • Warning:  SUID File (11 Files) and "Permissions Differ" - No Install Disc

    Hello,
    Have had my black macbook for about 3 1/2 years now (leopard) and having problems with it being really sluggish and freezing up. Additionally, the fan is coming on a lot and being really loud. I have checked activity monitor (all processes) and nothing is running over 12...Question is are the "warning suid files" and "permissions differ" the source of these problems? I can't find my original install disc (have one for my i mac but no good I hear.) Guessing I need to go to the genius bar to fix this issue...Thanks, PoorGradStudent

    Hello and welcome to the discussions, Those warning are normal and nothing to worry about.
    While your at the genius bar see if they will run a diagnostics test on your laptop. Note, if your problems only show up after it has been on for an hour, get there an hour early and warm it up.
    No use in have them look at it if you can't replicate the problem.
    Cheers,
    Glynn

  • Disk permissions problem after installing Leopard

    Hi!
    I performed a Repair Permissions after installing Leopard. Firstly, I noticed that this procedure took a lot longer than before the upgrade. I also received the following error messages -

    What does all this mean? How can I fix it?
    Thanks.

    You suggest I reinstall all of Leopard and then update to 10.5.1?
    No. Download and install the standalone 10.51 updater without reinstalling the entire OS.
    I found 2 Remote Desktop updates (Client and Admin) - version 3.2. Are these for Leopard?
    Use the client version.
    How will this help my problem?
    Those are status messages. You don't have a problem.

  • Apple Raid Card panic on Mac Pro Early 2008 after installing SSD as an enhanced JBOD.

    I recently installed a SSD drive in my Mac Pro to replace an aging, original boot drive.  I have an Apple raid card with 3 other hds attached - all in an enhanced JBOD configuration.  After installing the SSD from OWC (3G Electra SATA II Compatible) everything appeared to work fine.  But after 36 hours I received a apple raid card kernel panic alert.  See below for diagnostic crash log.  OWC support says that their drive should work fine - now I am not so sure.  Anyone out there with suggestions/solutions is most welcomed.

    RE: Mac Pro Replacement Graphics cards

    3) "Mac Edition" cards ...
    ... show all the screens, including Boot up screens, Safe Mode, Installer, Recovery, debug screens, and Alt/Option boot screens. At this writing, these choices include:
    1) Apple brand cards:
    • Apple-firmware 5770, about US$250** works near full speed in every model Mac Pro, Drivers in 10.6.5
    • Apple-firmware 5870, about US$450
    2) "sold in the Apple store" cards
    • NVIDIA Quadro 4000, about US$1200
    • NVIDIA Quadro 5000, about US$2500
    3) "Mac Edition" cards -- REQUIRE 10.8.3 or later:
    • SAPPHIRE HD 7950 3GB GDDR5 MAC Edition, about US$480** Vendor recommends Mac Pro 4,1
    • EVGA GTX 680 Mac Edition, about US$600
    The cards above require no more than the provided two 6-pin aux power connectors provided in the Mac Pro through 2012 model. Aux cables may not be provided for third-party cards, but are readily available.
    If you are Meet ALL of these:
    • running 10.8.3 or later AND
    • don't care about "no boot screens" etc AND
    • can re-wire or otherwise "work out" the power cabling, THEN:
    You can use many more cards, even most "PC-only cards"

  • Disk Permissions differ after a day

    Hi,
    Just in the past couple of days my computer has been running very slowly. It has been taking 15 minutes to log in, so I fire up Disk Utility, Verify permissions and there are a heap of differing permissions. I repair permissions and the machine runs fine. The next day the computer is back to being slow. I go through verifying permissions and there are a heap of differing permissions again.
    My Hard Drive is farily full, I have 2 partitions, the Macintosh HD partition is running at 7gb free and the extended partition has 32gb free. I don't know if a full disk would be causing these errors.
    Here is a log of the disk utility.
    Any help would be greatly appreciated.
    Thanks

    I have no idea but repairing permissions or not would not likely have any impact on the computer's login time (do you actually mean login as in entering your username and password or do you simply mean boot time?)
    If your computer runs slow look for other possible causes such as incompatible third-party software you have installed or corrupted caches and/or preference files. See the following:
    Kappy's Personal Suggestions for OS X Maintenance
    For disk repairs use Disk Utility. For situations DU cannot handle the best third-party utilities are: Disk Warrior; DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption; Disk Warrior 4.x is now Intel Mac compatible. TechTool Pro provides additional repair options including file repair and recovery, system diagnostics, and disk defragmentation. TechTool Pro 4.5.1 or higher are Intel Mac compatible; Drive Genius is similar to TechTool Pro in terms of the various repair services provided. Versions 1.5.1 or later are Intel Mac compatible.
    OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) If this isn't the case, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep. Dependence upon third-party utilities to run the periodic maintenance scripts had been significantly reduced in Tiger and Leopard.
    OS X automatically defrags files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive. As for virus protection there are few if any such animals affecting OS X. You can protect the computer easily using the freeware Open Source virus protection software ClamXAV. Personally I would avoid most commercial anti-virus software because of their potential for causing problems.
    I would also recommend downloading the shareware utility TinkerTool System that you can use for periodic maintenance such as removing old logfiles and archives, clearing caches, etc.
    For emergency repairs install the freeware utility Applejack. If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the commandline. Note that AppleJack 1.5 is required for Leopard.
    When you install any new system software or updates be sure to repair the hard drive and permissions beforehand. I also recommend booting into safe mode before doing system software updates.
    Get an external Firewire drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
    1. Retrospect Desktop (Commercial - not yet universal binary)
    2. Synchronize! Pro X (Commercial)
    3. Synk (Backup, Standard, or Pro)
    4. Deja Vu (Shareware)
    5. Carbon Copy Cloner (Donationware)
    6. SuperDuper! (Commercial)
    7. Intego Personal Backup (Commercial)
    8. Data Backup (Commercial)
    9. SilverKeeper 2.0 (Freeware)
    10. MimMac (Commercial)
    11. CloneTool Hatchery (Shareware)
    12. Clone X (Commercial)
    The following utilities can also be used for backup, but cannot create bootable clones:
    1. Backup (requires a .Mac account with Apple both to get the software and to use it.)
    2. Toast
    3. Impression
    4. arRSync
    Apple's Backup is a full backup tool capable of also backing up across multiple media such as CD/DVD. However, it cannot create bootable backups. It is primarily an "archiving" utility as are the other two.
    Impression and Toast are disk image based backups, only. Particularly useful if you need to backup to CD/DVD across multiple media.
    Visit The XLab FAQs and read the FAQs on maintenance, optimization, virus protection, and backup and restore.
    Additional suggestions will be found in Mac Maintenance Quick Assist.

  • Many permissions differ after recent updates

    I have just updated to iTunes 8.2.0, Garageband update 5.0.2 and Quicktime 7.6.2 on my 24"iMac running 10.5.7 and the number of "unrepairable" permissions has risen from 30 (which has been the constant number since installing 10.5.7) to an eye watering 8.
    This worries me.
    Is this what anyone else is seeing?

    Just in case anyone wishes to know what the "unrepairable" permissions were here is a list. As most if not all have a symbolic link they can probably be safely ignored. I have, however, sent the list to Apple in case it is of use to them when tidying things up in future releases:-

  • IMovie slow to load after installing SSD

    Hi everyone, I have just installed an SSD in the spare optical drive bay of my Mac Pro and added RAM.
    (Specs below.) I did a clean install of SL.
    Before I did this I was booting from the 320GB drive that came with the computer and I have all my photos and video on a 2 drive RAID 0.
    Before iMovie would launch in 11 seconds for the first launch and 6 seconds thereafter. That included loading projects and events.
    Now it takes about 1 second to launch but 40 seconds to load the projects and events every time.
    I have ditched pref files and retried but no good.
    Any suggestions?

    Yes, but the test is based on a 128k file, written many many times. That's fine with that, but video files imported into iMovie's cache area are not 128k large; they are much much larger especially when you're working with HD footage! You can also do another test and that is to completely wipe out your SSD drive and start over. After install, run iMovie 11 again and see. If it loads fast with the events, then you know that's the best that drive can do under your typical usage. However, if the drive still behaves exactly the same before and after a clean install, then something is wrong with the drive.
    I don't believe there's any issues with your optical bay since it supports a SATA connection. You can check under system profile to see what link mode it is in now. For your Sandforce SSD, ideally it should be negotiating at 3Gbps rather than 1.5.
    Personally, I have the same drives RAIDed in RAID 0 on my PC and while it is fast, it does slow down when I did too many big video writes despite what they claim as being trouble TRIM free. But with the slight slowdown, it is still much better and faster than a physical RAID 0 hard drive.

  • Permissions problems after installing new hard drive

    I backed up my old hard drive with SuperDuper!, then installed a new hard drive. When I tried to install my backup on the new hard drive with Disk Utility, it would work fine and then hang. It wouldn't finish, even overnight. So I installed a clean copy of leopard on the new hard drive, and then used Migration Assistant to move everything over from my backup. Worked great, until I actually tried to use the computer. Tons of permissions issues, mail and address book wouldn't run, Skype won't run even after installing an upgraded version, etc. What's weird, is my main account is an administrator account, but logging on as root and trying to remove admin permissions from my main account, the checkbox is greyed out! I also don't have a UID 501 on the system. I'm 502, and my wife's account is 503. I can't fix permissions from the finder, and in certain cases can't get them changed in terminal logged in as root. I don't know how to get my data from my old hard drive (which is running 10.5.1) to my new hard drive (also 10.5.1) Please help me! Thanks.

    Hey Shawn,
    Have you looked at the permissions with "Get Info"? Are they listed as belonging to "unkown user"?
    First of all, see the Apple doc <href="http://docs.info.apple.com/article.html?artnum=306876">Administator user changed to standard.
    After you clear that up, you'll probably have to remove the "unkown user" and add your user as the owner of all your folders. During that process, finder will probably crash. At that point, try running <a href="http://discussions.apple.com/thread.jspa?messageID=5670342#5670342>this terminal command described in "mlaster's" second posting.
    Good luck!

  • Intermittent failure to boot after installing SSD

    I have recently installed new RAM and an SSD in my late 2009 MacBook Pro, running OS X 10.6.8, and it now frequently hangs when I try to start it up. Here are  details:
    In recent weeks I noticed signs that seemed to point to a failing hard drive. I took the machine to a Genius Bar. The genius tried Disk Utility and a quick diagnostic and could not reproduce an error, but he noted many, many I/O errors recorded in a log file.
    He said I probably had a failing disk, but it might be a cable issue. He gave me two options: leave the machine with Apple overnight to run diagnostics and perhaps repair if the problem was confirmed, or just take a chance and replace the drive myself, for less money and less downtime.
    I went to a local computer store, and the salesman there noted that I was using relatively little disk space. He suggested that I swap my failing 160 G disk for a smaller, 120G solid-state drive, which happened to be on sale. I agreed and also bought some new RAM.
    I installed the drive and RAM, partitioned the disk (with HFS journaling), and restored my files with Time Machine. For that day and the next, everything worked perfectly.
    The second day after the installation, the system hung while starting up. The Apple logo appeared, the gray spinner appeared, and it just spun. I tried resetting PRAM. I tried safe restart. I started up from the install disk and ran Disk Utility: no problems found. I repaired permissions. I took out the new RAM and put back the old. In some cases after trying these steps, the system booted fine — once. In others, it would not boot the first time, but would boot on the second or third attempt. I reinstalled OS X and updated software. The problem persisted. I installed some freeware to enable trimming the new disk. No better.
    I have booted many times in verbose mode. During the unsuccessful boots, there is usually a message "Bug: launchctl.c: 3557 (23930):6 ioctl(S6, SIO CAIFADOR_IN6, &ifra6) ! = -1". The next line is the command "fsck_hfs", and the machine hangs. Eventually it sometimes spits out "launchctl: please convert the following to launchd: /etc/mach_init.d/dashboardadvisory.plist". If I let it go for a long time, I sometimes come back to find a long string of I/O error messages, to the effect that media was expect to be there but wasn’t. I think every time I have gotten the launchctl message, it has booted successfully on the next try.
    During the successful boots in verbose mode, everything happens so quickly that it is hard to say what is going on, but I don’t think it is running fsck_hfs. If it boots successfully and I give it a heavy I/O task, like doing a virus scan, everything works fine. If I run Disk Utility off the installation disk, it says the disk appears to be OK.
    I started the machine in single user mode and ran fsck manually. It gave me reports similar to running Disk Utility, and told me the disk appeared to be OK. It then gave me the prompt for a new command. I typed "exit". It responded "logout". And hung.
    One last thing: I just tried a couple of times to restart with the Apple Hardware test. Despite holding down the D key, the test failed to load, and after a long pause, the machine attempted a normal start-up.
    Any insights?

    Thanks, sanjampet, I have an old copy of Spring Cleaning, and I'm letting it sift through my files right now.
    I have done some investigation on other forums, and there are some suggestions that the problem is associated with  the make and model of drive that I installed. That is, this might not be an OS X issue so much as a hardware or firmware compatibility issue.
    I bought the device on the recommendaiton of a salesman at a physical store, without consulting the manufacturer's webpages or online reviews. It turns out that many of those reviews are negative. It also turns out that although the manufacturer says that the device is suitable for Macs, the manufacturer does not yet offer a way to update to the most recent firmware unless the device is connected to a machine running Windows or Vista. And there are reports that some units out in the stores were shipped with outdated firmware, which might be the root cause of my problem. Or maybe not.
    So here's the painful lesson: don't buy new hardware without first double-checking the specs, the support, and the reviews.
    If anyone has a more hopeful insight into the problem, please let me know!

  • Problems after installing SSD in 2009 MBP

    I'm using a 256gb OCZ Octane SSD and decided to dual HDD. Im using OSX Moutain Lion with 8gigs of RAM. After I installed the SSD I came upon problems. My mbp freezes on start up: it has the apple and the spinning loading icon and stays like that for a couple minutes before restarting itself and just staying a grey screen. It boots in safe mode and by chance boots if I manually tell it to boot from the SSD. How do I get my mbp to boot from the SSD with the expected speed of the SSD?
    Also, with the 2nd internal HDD how do I find my files that I'd like to keep on it? The HDD doesnt show up in the finder as an accessible volume although it does appear when I open disk utility. My goal is to have boot up, apps, and games on the SSD but music, movies, files, etc on the HDD.
    I have the SSD located in the original HDD spot and the HDD in the optibay. Are those fine locations for my model (5,2)? I read somewhere else online that early models like mine should put the SSD in the optibay and keep the HDD where it is.
    Please help!
    I did do a clean install osx mountain lion but migrated users and apps. would a clean install of everything work better?

  • Optical drive not showing up after installing SSD HD on satellite L75-B7150

    I just installed an ssd drive in my satellite L75-B7150. I had to unscrew the locking screw on the optical drive and slide it out. Now it wont show up in this PC windows 8.1. it does have power and the light led comes on a while with a disk in it but then goes out. It seems to be plugged in ok as far as the power.Could it be a driver problem? there doesn't seem to be any specific drivers for it.The drive probably isn't making contact with the sata connection. Does any one know a trick to putting them in. the optical drive pushes in after the case is snapped together so unsnapping the case wouldn't help me.

    make sure it is selected as the startup disc.    system preferences>startup disc> make sure new hdd is the default startup disc.

  • Magic Mouse stumbles after installing SSD in Lion

    For general information.
    Sunday while spring cleaning my trusty Mac Pro 1.1 2006-2007 running Lion I decided to install Crucial's M500 SSD. It was easy and no issue loading Lion.
    Then the Magic Mouse kept staggering and freezing up. Searched here and throughout the internet. I put back the original hard drive with all my setting and it kept lagging.
    Just now as I was going to post for help I turned my Mac Pro around from the usual postion I put it in and lo and behold the mouse is working fine again. I loved the Mac Pro closer. Mouse was fine. I turned it around where the front of the Mac Pro is less than 8 inches from the mouse and the symptoms return.
    Interesting huh?

  • MacBook Pro slow shutdown after installing SSD drive

    Hi,
    Just got a new 256GB SSD drive and installed it in my Macbook Pro, super super fast might I add. Startup in a couple of seconds, and apps open very fast. The only problem is the shutdown time, it takes over a minute to shutdown, really strange. I've read this post;
    http://discussions.apple.com/thread.jspa?messageID=13097765
    But this does not solve my problem. Any ideas what could be the problem?

    Have you tried booting into your Recovery partition (holding down the Command and R keys whilst booting).
    I don't know why an iTunes update would cause your MBP to shutdown and not turn back on. If you can't boot into your Recovery partition, try running the Apple Hardware Test (if you can - if you can't, it's time for a trip to your local Apple Store or AASP).
