Repairing permissions before and after updating software

What is the reason to repair permissions before and after updating software? This may sound like a stupid question to many of you, but I am new to computers and I am trying to learn how and why of some of the things of my PowerBook. I installed some updates without repairing permissions. Did I install some software updates the wrong way? Thank you.

This is a topic which will draw as many emphatic for and against responses as overnight shut down or not, defrag or not, optimise or not, and so on.
I agree with Neil. I believe that OS X has progressed sufficiently that repair permissions has become redundant and so I do not do it on any regular basis.
Some folk may refer you to an Apple Support Article 303602. That Article in its 4 May 2006 version, titled "Top 10 Tips to Keep Your Mac in Top Form" suggested Repair Permissions should be done "after upgrading or installing new software". The Article was however revised on 15 May 2006 to be titled "Top Tips to Keep Your Mac in Top Form" and the item on Repair Permissions [along with two other recommended maintenance tips] was removed. It is my view that the conclusion to be drawn here is that Apple no longer considers Repair Permissions to be a required maintenance procedure.
Many users have adopted a "Repair Permissions" mantra for a cure-all over several years. I dropped it sometime in 10.3.
But, to each his own.

  • Should I repair permissions before or after updating to Mac OS X 10.7.2?

    Hi,
    Should I repair permissions before or after updating to Mac OS X 10.7.2? or should I fix permissions before and after the update?

    This is not a routine maintenance. Upgrades can be screwed up if the system that is upgraded is screwed up. I believe in a "better safe than sorry" approach. If you repair permissions and the hard drive prior to an upgrade then if there be a problem perhaps that problem will not propagate to the new upgraded system. If there are no problems doing the repairs is harmless.
    When it comes to the topic of permissions repairs there are many opinions but not much fact. In other words there doesn't appear to be a formal analysis of whether repairing permissions is only useful when a permissions problem arises. But there is a lot of anecdotal evidence suggesting that a repair both before and after a major system upgrade can reduce the risk of problems.
    This is my opinion on the matter. I do not generally disagree with Niel or MacJack, but as I said I prefer to be safe rather than sorry.
    Here's my general approach:
    How to Install Lion Successfully - You must have Snow Leopard 10.6.7 or 10.6.8 Installed
    A. Repair the Hard Drive and Permissions:
    Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. Then select Disk Utility from the Utilities. 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 installer. Now restart normally. 
    If DU reports errors it cannot fix, then you will need Disk Warrior (4.3.) if DW cannot fix the drive, then you will need to reformat the drive and reinstall Snow Leopard.
    B. Make a Bootable Backup Using Restore Option of Disk Utility:
    Open Disk Utility from the Utilities folder.
    Select the destination volume from the left side list.
    Click on the Restore tab in the DU main window.
    Check the box labeled Erase destination.
    Select the destination volume from the left side list and drag it to the Destination entry field.
    Select the source volume from the left side list and drag it to the Source entry field.
    Double-check you got it right, then click on the Restore button.
    Destination means the backup volume. Source means the internal startup volume.
    C. Important: Please read before installing:
    If you have a FireWire hard drive connected, disconnect it before installing the update unless you will boot from this drive and install the update on it. Reconnect it and turn it back on after installation is complete and you've restarted.
    You may experience unexpected results if you have installed third-party system software modifications, or if you have modified the operating system through other means. (This does not apply to normal application software installation.)
    The installation process should not be interrupted. If a power outage or other interruption occurs during installation, use the standalone installer (see below) from Apple Downloads to update.  While the installation is in progress do not use the computer.
    D. To upgrade to Lion:
    Purchase the Lion Installer from the Mac App Store. The download will start quickly. Lion is nearly 4 GBs so a fast internet connection is essential. Download time could run upwards of 4 hours depending upon network conditions and server demands at the time.
    Boot From The Lion Installer which is located in your Applications folder.
    Follow instructions for installation.

  • Oracle Alert: Access before and after update values of a table column

    We have a requirement where a notification needs to be sent when 'END_DATE' attribute (column in a table X) is set, in an Oracle Applications form.
    I have defined an Event based Oracle Alert which fires 'On Update' of the table X.
    Could anyone please let me know as how to access the value of 'END_DATE' before and after update (i.e :new.END_DATE and :old.END_DATE) in the sql query of the alert.
    The need to use the before update and after update values of the attribute 'END_DATE' is that if we add the condition END_DATE is not null, the alert is sent even if any other attrbutes are updated in the Oracle form which is not the intended behavior.
    Appreciate any help.
    Thanks

    Hi
    use selectionlistener for your first table then add clientlistener and serverlistener so that you will get the rows on click in back bean.
    then get second table vo and and create and add row for that view object. add partial target to refresh your second table from back bean.
    on click of save call commit operation.

  • Triggers before and after update

    Hi
    I would like to add triggers before and after update for the following code. I would be thankful if someone give some guidance
    update per_all_people_f a
    set start_date = (select min(effective_start_date)
    from per_all_people_f a1
    where a1.person_id = a.person_id)
    where person_id in (1114,115);Thanks
    anna

    Hi
    I was unable to answer you. I agree with Peter . Also i want to add
    that in HRMS you should check what triggers are already on that table and be carefull with creating your own one. With your own trigger you can influence on some application logic you know.
    ( And i hope that is a table first of all :) - but as i know _F at the end of table name means table  )

  • Everyone:  This time repair your permissions before and after 10.4.8 update

    Hello All,
    Just a reminder for all those who are updating to OS 10.4.8.
    While many people do ignore all the recommendations that we provide and still come through fine, please do consider observing the following to minimize your problems.
    To insure the best chance of success, please consider downloading the Combo Updater for your computer instead of using Software update.
    For PowerPC Mac's, this would be:
    http://www.apple.com/support/downloads/macosx1048comboupdateppc.html
    For Intel Macs, this would be:
    http://www.apple.com/support/downloads/macosx1048comboupdateintel.html
    The benefit of using the Combo Updater, is that it replaces all system files that have been changed since the last major release (in this case since 10.4.0).
    So, if you have any system files that have become corrupted, the Combo Updater will very likely over-write those, and spare you the headaches that come from updating an operating system that has problems that just haven't come to the surface yet.
    In many cases, you can have problems that have not come to the surface, and the "Delta" or Software update method will bring them out to bite you. The reason for this, is because the Delta / Software Update version only changes files that have changed since 10.4.7. And, it works more in a "patch" fashion. So, if there is a problem in one of the files being patched, then the update will cause you some major headaches.
    Going with the larger "Combo" update over-writes almost all the System files with clean versions instead of just making patches. So, it is frequently much more successful.
    Now, with that said, before you update, you should make sure your permissions are all set properly. If your permissions are wrong, then your update will likely have trouble.
    So, go into "Disk Utility" in the Applications --> Utilities folder and repair your permissions.
    Start by selecting your hard drive on the left window of Disk Utility. Then, go down and click on the "Repair Permissions" button. Once it's completed, then exit Disk Utility.
    Now, it is also extremely important to make sure all running programs are closed before you install any system update. So, go ahead and restart your computer.
    Restarting will make sure that all programs are closed, and that nothing weird is stuck in memory before you install.
    If you have anti-virus programs running, then disable or deactivate them first (you don't want them interpreting this as unauthorized modification or it might prevent certain files from being updated).
    Now, with your computer freshly restarted, install the Combo updater you downloaded.
    When prompted, click on the "Restart" button when prompted.
    Now, the computer will startup, but sit at the spinning wheel for several minutes. It will eventually restart again on it's own. And, finally, it will start-up all the way and you'll be back at your desktop.
    Now, immediately go back to Disk Utility and repair permissions as you did in the previous step. You will likely see several permissions that have been repaired. In my case, I had dozens of CoreAudio, Widgets, and other permissions that needed repair. Once permissions have been repaired, go ahead and restart one last time. This makes sure that everything is set and then cleaned-up.
    Once it reboots, begin using it and enjoy.
    Now, this may sound like a lot. But, it really is simple. It just reads like a lot of stuff.
    And, of course, you are free to ignore this and just install it however you like. Many people have their own ideas here. And, many people say you don't have to do anything to prepare. But, for those that have had huge problems in the past, these extra steps will usually save you the major headaches that tons of people inevitably have with every new update.
    Anyway, I hope this helps to save at least a few of you any problems. If you don't agree with the ideas above, just ignore it and do as you like.
    But, if you want a little extra piece-of-mind and a better chance at success, then please consider exercising this extra caution.
    And, for the record, I have updated my machines to 10.4.8 (within minutes of the update being available) and it is working perfectly smooth on my systems.
    I hope you find this helpful.

    mhunter, thanks and good that you take the time and effort again to remind everyone that it does take an effort to do a major OS update, to ensure maximum stability.
    So far my 10.4.8 Update is a-okay, and I have had many trouble-free updates since installing 10.4
    I too practice rigourously and "religiously" before and after an OS or Security Update, but I normally use Software Update, equally successful:
    1. Before Startup, UNPLUG all external devices, left only keyboard, mouse and internet connection, unless they are all wireless.
    2. Startup, disable NAV if any, Repair Disk Permission. Restart again, Repair Permission again.
    3. Do Software Update
    4. Restart, Repair Permission
    5. Shutdown, plug everything back
    6. Startup Mac, use Mac
    So far these steps have been keeping all my macs both at home and at work very very stable and healthy.
    Maybe, just maybe if everyone here, all mac users were to follow these steps, yes they can be a hassle, yes they can take up some time, but then there will be less less complains and "blasts" at Apple, just because perhaps themselves have been too careless or negligance in performing updates.
    Cheers

  • Error uploading file to web before and after updating

    Hi,
    I'm running adobe muse on a mac 2013 yosemite. I changed from the original version of adobe muse to the 2014.2 version, just to let you all know.
    Earlier today, I woke up and one of my two websites I've created in the original version of adobe muse had lost the information required to upload to FTP Host. I retyped in my information, and it started to upload my website. Eventually it hit the 61% mark, and said that it was "connecting to the FTP host" for a really, really long time. I waited about 20 minutes- nothing happened. So I then decided to update adobe muse to the 2014.2 version.
    After updating, I tried uploading my site to the web again. I put in virtually the same information as before, and now I'm getting an error message saying "Could not sign in. Check your network connection and try again. If this problem persists, try again later."
    Can anybody help me here? My website is hosted by GoDaddy.com, just to let you know.
    Thanks in advance,
    Gavin

    Muse 2014.3 was released last week , please tr y to update Muse and then check.
    Thanks,

  • Cannot connect to itunes store before and after update ios 8.2,  What can i do ?

    I updated to iOS 8.2 about 2 hours age and I get an error saying "cannot connect to iTunes Store" every time I try to update existing apps or download new apps. I restarted my phone, disconnected from wifi, reconnected to wifi...nothing is working. Under iTunes & App Store settings, I signed out and now get the "cannot connect to iTunes Store" message when trying to sign back in. I know my Apple ID and password are correct.

    Based on the numerous posts regarding iTunes and the App Store, there appears to be an issue at Apple's end. Although Apple has not provided any indication on the cloud status page.
    Do not change your settings.

  • IPad 2 cannot connect to Wifi before and after updating  PLEASE HELP

    i have been using iOS 5.1.1 till today.. the connection to wifi stopped working.. it slowly faded away and today i woke up and could not connect to My wifi at all, i have decided to update my iPad to iOS 7.0.4 but the problem is there
    what should i doo ??

    It could be a problem with your WiFi router or your iPad.
    If you are having WiFi problems it is necessary to isolate whether the problem is with your network or your iPad. Note: Do NOT consider your network to be blameless if some other devices can connect to it.
    First, test your iPad on some other WiFi networks: a friends, Starbucks, Barnes & Noble, etc.
    If it works well there then the problem is probably with your network. Try restarting your WiFi router by removing power for 30 seconds. If that does not help check for a firmware update for your router. If none exists which corrects the problem consider replacing the router.
    If your iPad does not function well on other networks it possibly has a hardware problem. You could try Settings > General > Reset > Reset Network Settings to see if that corrects the problem. If not, contact Apple Support or visit an Apple store for evaluation. They can provide a replacement if your iPad is bad.
    If you need more help please give the make, model, and version of your WiFi router and how you have it configured.

  • I regularly use Firefox and noticed lately that it is using a large amount of memory....sometimes up to 500 mb in a session. In addition, it's been slower and tends to hang up a lot. This occurred both before and after updating to the newest version.

    I don't really know what else to detail. What would you like or need to know?

  • Before update and after Update trigger

    Hi,
    I am following the below approach to overcome ORA-04091: table XXXX is mutating error.
    1. In the after update row level trigger i am capturing rowids of changed rows into a table type (of type rowid) defined in a package.
    2. In the after update statement level trigger i am using the data from the table type ( that got populated in the first step) to do my work.
    3. In the before update statement level trigger i am resetting the table type defined in the package.
    Now, can the below situation occur causing the system to fail
    1. A Update to the table occurred causing the before update statement level trigger to fire and reset the table type.
    2. After that row level after update trigger gets executed and captures the required data.
    3. Now before the after update statement level trigger gets executed a new update to the table happened ( to some other row as multiple users are using the application) causing the
    before update statement level to fire and erase the data from the table type?
    I want to know if above situation can occur or is the execution or before and after update triggers atomic?
    Thanks for helping.
    TIA
    Harsha

    A collection in a package is local to the session. And a given session can be processing one SQL statement at a time. So any concurrent updates would be happening in a different session with a different logical collection.
    You may encounter problems if your session is trying to update the same rows that other sessions are trying to update (whether via the original update statement or via the updates issued by the trigger). You could encounter performance problems because of row level locks or you could encounter deadlocks. But your session's collection won't be initialized by some other session's actions (other than DDL that replaced the package itself).

    I've fixed the problem - I think.
    I forgot I had the program "Little Snitch" installed on my computer. So I went into it and saw that it was blocking most of my connections for all the programs I use on a daily basis. Once I lifted the RULE to those certain programs - BAM - everything came back to life in an instant!

    After updated software on mac mini with os x 10.7.5 and restart the mouse pointer after about 30 sec. converted to the rainbow wheel and I can't control the computer. The rainbow wheel was runnig 8 hrs and I turn off mac mini by power button, then I turn on mac mini with key Shift and p/w, checked HD. My HD has

    Please read this whole message before doing anything.
    This procedure is a diagnostic test. It won’t solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
    Third-party system modifications are a common cause of usability problems. By a “system modification,” I mean software that affects the operation of other software — potentially for the worse. The following procedure will help identify which such modifications you've installed. Don’t be alarmed by the complexity of these instructions — they’re easy to carry out and won’t change anything on your Mac.  
    These steps are to be taken while booted in safe mode.
    Below are instructions to enter some UNIX shell commands. The commands are harmless, but they must be entered exactly as given in order to work. If you have doubts about the safety of the procedure suggested here, search this site for other discussions in which it’s been followed without any report of ill effects. 
    Some of the commands will line-wrap or scroll in your browser, but each one is really just a single line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, and you can then copy it. The headings “Step 1” and so on are not part of the commands. 
    Note: If you have more than one user account, Step 2 must be taken as an administrator. Ordinarily that would be the user created automatically when you booted the system for the first time. The other steps should be taken as the user who has the problem, if different. Most personal Macs have only one user, and in that case this paragraph doesn’t apply. 
    Launch the Terminal 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 Terminal in the icon grid. 
    When you launch Terminal, a text window will open with a line already in it, ending either in a dollar sign (“$”) or a percent sign (“%”). If you get the percent sign, enter “sh” and press return. You should then get a new line ending in a dollar sign. 
    Step 1 
    Triple-click the line of text below to select it:
    for k in /Sy*/L*/Ex*/{,.?}*.kext; do test -f "$k/Contents/Info.plist" && /usr/libexec/PlistBuddy -c "Print :CFBundleIdentifier" "$_" | egrep -qv "apple|Accusys|ArcMSR|ATTO|CalDigit|HighPoint|hp-fax|JMicron|print|SoftRAID|stex" && echo $k; done | open -f -a TextEdit
    Copy the selected text to the Clipboard by pressing the key combination command-C. Then click anywhere in the Terminal window and paste (command-V). A TextEdit window will open with the output of the command. Post the contents of that window, if any — the text, please, not a screenshot. You can then close the TextEdit window. The title of the window doesn't matter, and you don't need to post that. No typing is involved in this step.
    Step 2 
    Repeat with this line:
    sudo defaults read com.apple.loginwindow LoginHook | open -f -a TextEdit 
    This time you'll be prompted for your login password, which you do have to type. Nothing will be displayed when you type it. Type it carefully and then press return. You may get a one-time warning to be careful. Heed that warning, but don't post it. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator. 
    Note: If you don’t have a login password, you’ll need to set one before taking this step. If that’s not possible, skip to the next step. 
    Step 3 
    Repeat with this line:
    ls -1A /e*/mach* {,/}L*/{Ad,Compon,Ex,Fram,In,Keyb,La,Mail/Bu,P*P,Priv,Qu,Scripti,Servi,Spo,Sta}* L*/Fonts 2> /dev/null | open -f -a TextEdit
    Important: If you formerly synchronized with a MobileMe account, your me.com email address may appear in the output of the above command. If so, anonymize it before posting. 
    Step 4
    osascript -e 'tell application "System Events" to get name of every login item' 2> /dev/null | open -f -a TextEdit 
    Remember, Steps 1-4 are all copy-and-paste — no typing, except your password. Also remember to post the output. 
    You can then quit Terminal.

  • After updating software, apple tv no longer accesses mob.tv and wsj

    After updating software, my apple tv no longer accesses MLB.TV and the WSJ.  It shows a spinning icon, sas accesing mlb., but never finishes.
    This happened once before with an upgrade and the solution was to update using a USB wire.  I took the apple tv to the store, and they did this (or they said they did), but the wired connection to MLB NO LONGER WORKS.  It will work as a wi fi, but will not work with wire.  Help!  How can I get mlb back p and running for the 5 days of the year I want it most.

    Is your Apple TV correctly connected to the network (check you don't have an IP address that staqrts with 169)
    Have you checked homesharing is still set up properly, what about your computer firewall, is set to allow access for iTunes, you might try turning it off too.
