I accidentally changed permissions of all the files of my system drive (10.8.5)

Hi,
By mistake, I accidentally changed the permissions for all the files of my entire system drive. On the root of my system drive, I've put on "Read and Write" for Admin, staff, and everyone, and applied this change to all the files of my entire drive.
Since I did that, I experiment issues with some applications which worked perfectly before that : when I try to open some applications (not all, just some), it tells me things like "something is wrong in the installation of the application", or "can't open the following application", or it simply just doesn't open it.
I have to mention I have no Time Machine or backups of my drive, as I bought my mac three days ago and spent the two last days installing plugins and applications on my drive (for audio production). So I can't replace my drive with a backup of the system before I accidentally changed all permissions.
Also, I repaired permissions on my drive with the disk utility, but all the app that doesn't work are from external developpers (not apple).
Is there any way to "repair" this without having to reinstall all the app that are causing problems ? It would be a pain for me as I just spent 48hours installing everything...
Thanks for anyone that could help...

You need a backup, preferably more than one. This is an example of why.
Try setting up another admin user account to see if the same problem continues. If Back-to-My Mac is selected in System Preferences, the Guest account will not work. The intent is to see if it is specific to one account or a system wide problem. This account can be deleted later.
Isolating an issue by using another user account
If the problem is still there, try booting into the Safe Mode using your normal account. Disconnect all peripherals except those needed for the test. Shut down the computer and then power it back up after waiting 10 seconds. Immediately after hearing the startup chime, hold down the shift key and continue to hold it until the gray Apple icon and a progress bar appear. The boot up is significantly slower than normal. This will reset some caches, forces a directory check, and disables all startup and login items, among other things. When you reboot normally, the initial reboot may be slower than normal. If the system operates normally, there may be 3rd party applications which are causing a problem. Try deleting/disabling the third party applications after a restart by using the application un-installer. For each disable/delete, you will need to restart if you don't do them all at once.

HT4889 I have accidentally created another account when using Migration Assistant to a new MBA. How do I now 'migrate' all the files from both accounts into one to save myself having two accounts, both of which are me? Help?

I have accidentally created another account when using Migration Assistant to a new MBA. I have read that I probably should not have skipped migration in the initial set up and the problem would have been avoided but, alas, here I am. Does anyone know how I can 'migrate' all the files from one of the accounts that has been created to the other, so then I can delete it and have a single user on the computer seeing as I am the only person using it? I have read starting again, if this is the way to go, where is the best place to start 'starting again'?

Yes definitely should see it but its not coming up (I don't think) when I log out of 2nd user and into the main account. Opening finder in the 2nd account, I can obviously find the public folder because thats where I dropped all the files, but when in the main account, it can't be found. The only public folder that comes up is the folder for that account (main account) and it does not display files I'm looking for. Frustrating....
EDIT: Have found it through a round-about way but all music and photo and movie etc files have a red stop sign disallowing them from being transferred. Can you guess what the next question will be?

A form template .xsn file cannot be accessed. You may not have the required permissions to open the file

Hi there,
When a workflow task is assigned to a user, he cannot open a particular task. and
sees this error in browser:
A form template .xsn file cannot be accessed. You may not have the required permissions to open the file
The ULS Log for Correlation ID has these errors:
The XSN is null and its not a cross server issue. Most likely a permission issue
The XSN is null after attempting to get it from SiteAndWebCache
Please note:
- This user can open all other forms in the same location.
- If I increase his permission to Site Owner, he can open this form - but we cannot allow this.
- He was able to open it earlier - I made minor changes in the form and republished the workflow - since then he is having the trouble.
Any help will be appreciated!
Thanks.

Hi ran009,
Please check if that user has contributor permission on the list that the workflow associated and have Edit item permission on related task list/item.
Also check if the workflow form or other workflow files has been checked out or not. If yes, check it in and test it again. Check Wayne Fan’s post in this thread if you have trouble to check the check-out/in status of the task form.

I had Partitioned my Macintosh HD, so now it has two, Macintosh HD and Macinyosh HD 2, but the question is, my computer has an minor update OS X 10.8.2 to 10.8.3, i wan to move all the files as BACKUP to the Macintosh HD 2, but how? Thanks.

As long as the Macintosh HD 2 partition is just the same size as Macintosh HD to avoid problems in the future, then you can clone one to the other using Carbon Copy Cloner, then use Disk Utility to Repair Permissions on both and if you need too you can hold the option key down while booting and select the #2 partition to boot from.
However you need to set CCC to maintain a pure clone, or else by default it will save the changes between clone updates and overfill your #2 partition.
Also the #2 is merely a bootable backup alternative and for retrieving the rarely occuring deleted files, don't use #2 for storage or anything you want to save pernamently.
In addition you also need external clones and backups, as the machine may fail or get lost etc.,

Do all the computers require the same apple ID to share all the files?? Can i have two apple accounts on one device

Neither of those Apps allow you to (easily) add iWork documents created or edited on the device to your online storage, you need to be using a webDAV server to be able to do that. In fact pretty much all you can add from the iOS device is photos and video without resorting to convoluted workarounds, intermediate apps or emailing finished documents to yourself. You can on the other hand view most of the content of dropbox/sugarsync through those apps, which in a lot of circumstances is useful, but without it working in both directions these apps are far from an ideal solution.
E.g from the sugarsync website
Yes, this may not be of too much interest to the OP, I was only trying to clarify the situation with iCloud.com/iWork for you.
However that being said, there may be areas of interest for Computer to Computer syncing, given the recent changes made to iCloud.com/iWork. I wouldn't suggest iCloud sharing for archived documents, but for perhaps up to a couple of dozen documents in progress, iCloud sharing is now quite viable. If there is any chance at all of these documents being accessed on an iOS device then iCloud would become a preferred option to dropbox or sugarsync.

Is my website really lost? All the files are in my .Mac account but what?!

I have read several of the threads on the topic and have become quite disillusioned by the thought of having to start from scratch again. HELP!
I originally created my personal website, web.mac.com/username (I've moved the files to a different directory), several months back and had been using the previous edition of iWeb for its creation and maintenance. Since then my former computer, a MacBook, experienced a head crash that left me only with a backup that had been done 3 months prior. Since then, as I have inched my way through updating all of my work files, I have held of on doing anything with my website. I now want to edit it and with the upgrade (10/25/07) to a MacBook Pro and the new iWeb '08, I get that sinking feeling that this isn't going to end well.
My first issue (concern) has to do with how little conclusive and specific information is provided when it comes to the difference between a HomePage site and your other pages, namely when one has created their personal site using the web.mac.com avenue. Why is this process so ridiculously complicated? It really need not be and I wish someone took note of that.
As an avid user of MS FrontPage I was a little leery of using iWeb but was turned on by its ease of use and professional appearing pages and capabilities. However, after having invested all the time in making and publishing the site I am now concerned with the discussion and the seeming reality that I will have to start from scratch. All my files are sitting in my .mac account (I must admit in several locations as I got a bit zealous with ensuring that all the files were there in virtual triplicate) and yet from what I understand there is no way to get iWeb to point to those files so that you can simply begin the editing process again. Is that correct? When I go looking for 'Domain' files or anything of the sort that have been mentioned in discussions on and off this forum, I just don't see it. Is there no way to simply hop back on the train and edit my site again instead of starting from scratch? I'm just annoyed at opening iWeb only to see 'Site' and no other files! If there is a way that someone can share with me how to not have to redo everything, I am not against paying for the 'secret' as I think that the inability to simply 'import' or do anything that seems reasonable here is a bit frustrating. Can you begin again without starting from scratch?
I suppose if I am told that I can't then I will certainly have to turn my back on iWeb as even though MS FrontPage is not the best WYSIWYG, I can at least do directory management and things with manual code that iWeb has yet to incorporate (I do use iWeb Enhancer on my iWeb site to overcome this annoyance). I really need assistance as I would like to edit my website for the first time in over 4 months and as I said before will bail on iWeb if I have to start from scratch. Anyone willing to assist me, I again would be very appreciative. If there is a way, just let me know, I'm savvy enough with these types of things for the consultation process to take very little time at all.
HELP!!!

To say that "everyone says" is a bit like saying "just because." iWeb doesn't instruct, prompt, or even suggest you make a copy of your Domain file. I'm not sure if that policy has changed in the past few months since I last used the program. However, if this file is so important wouldn't one think that it would also be available on the server with all the other files one uploads or backs up to iDisk?! And so for the user of the program to 'not know' or 'know because everyone says' to make a copy of the Domain file is a bit confusing. Again, as I am often careful with website files, that was also the reason why I had made so many copies of the files within the website. I liked using iWeb (and again hope to in the very near future) but because of the limitations I mentioned before, I was only using it to for my personal site. Having used a plethora of other programs I just wanted to be able to keep using iWeb for my own stuff and then as the functionality became available would then use it for others. I should clarify, use it to 'publish' other sites. I'm certainly not going to get into an argument over it and if you'd like to have the last word, that's fine too, I just think that this is a real issue and that if the program worked like others that one could import the files back in, it wouldn't be a problem at all. However, at this present moment I have all the pieces of the puzzle except for the key. I have all the files but am missing a so called Domain file that I didn't even know had existed until this issue reared its head. Again, I'm annoyed at how difficult an otherwise simple issue to address would be. It's almost like saying that I should have known that the hidden 'exe' or 'dmg' file should have been one I thought about when doing any kind of back up and that despite having all the content files, they mean nothing. I will continue to search for the Domain file as I am hopeful that when my IT guy (Network Administrator) backed all my contents prior to the crash, he took every single file and that one should be among them if it is the location as had been previously mentioned. When my Mac crashed, it's as I said, a head crash on the hard drive and so there was no coming back from that. It was truly irreparable as I sent it off to a very reputable data recovery company to save it to no avail. However, I had done a full backup three months prior and am hopeful that the file is somewhere on my work server. If not, as you have pointed out, I'm screwed. And so while I still say that the program is to be blamed for some of its odd idiosyncrasies, I also accept that we'll have to agree to disagree on the issue.

I recently upgraded my old powerbook to an iMac. I've dumped the files of my backup drive into the new iMac. Is there a way to have access to all the files (new and old computers) when logged on as the same user vs. logging in and out to access each?

Sure-glad to help you. You will not lose any data by changing synching to MacBook Pro from imac. You have set up Time Machine, right? that's how you'd do your backup, so I was told, and how I do my backup on my mac. You should be able to set a password for it. Save it. Your stuff should be saved there. So if you want to make your MacBook Pro your primary computer, I suppose, back up your stuff with Time machine, turn off Time machine on the iMac, turn it on on the new MacBook Pro, select the hard drive in your Time Capsule, enter your password, and do a backup from there. It might work, and it might take a while, but it should go. As for clogging the hard drive, I can't say. Depends how much stuff you have, and the hard drive's capacity. As for moving syncing from your iMac to your macbook pro, should be the same. Your phone uses iTunes to sync and so that data should be in the cloud. You can move your iTunes Library to your new Macbook pro
you should be able to sync your phone on your new MacBook Pro. Don't know if you can move the older backups yet-maybe try someone else, anyways,
This handy article from Apple explains how
How to move your iTunes library to a new computer - Apple Support''
don't forget to de-authorize your iMac if you don't want to play purchased stuff there
and re-authorize your new macBook Pro
time machine is an application, and should be found in the Applications folder. it is built in to OS X, so there is nothing else to buy. double click on it, get it going, choose the Hard drive in your Time capsule/Airport as your backup Time Machine and go for it. You should see a circle with an arrow on the top right hand of your screen (the Desktop), next to the bluetooth icon, and just after the wifi and eject key (looks sorta like a clock face). This will do automatic backups of your stuff.

After running a disk checker, I have 30 gigs showing as used but unaccounted for anywhere, all the files I moved to an external hdd are still taking up space

I recently purchased a mac book air with the 128g SDD. After setting it up with all my desired applications I started to download some large media files. Knowing that I'm working with limited HDD space I hooked up a portable 1TB Drive, formatted it for MAC OS Extended (journaled) and moved all of my large files onto the back up drive. After moving all the files in my downloads folder to the trash, and then emptying the trash the space on the SDD "Macintosh HD" did not change. Currently reading at used 91g, available 29g (as seen in the disk utility program with the Macintosh HD highlighted). To find the 'mystery used space' I ran a program called 'DIsk Inventory X' on their opening screen the program shows a smaller capacity with 84g used and 27g free, running the program adds up the value of all the folders and applications on the HD only to discover their is only 54g's accounted for (this is realistic for the files and applications I currently have installed and intend to carry with me on a daily basis)
So my question is why is my SDD only filing up and not clearing the space I move to trash and empty, at this rate I won't have any space left.

sounds like the drive may be defective. remember that hardrives can crash at any time even if new and the drives in the air books are just really big flash drives. sound like you have an appointment for the genius bar to get it replaced.
i have one more possible fix but requires you download a free app called "OnyX". if you are not famliar with the power of this app, be carefull about what you have it do. hit me back up if you choose to go this route. other wise to the apple store you go my friend

How do I delete the files on my hard drive but keep all the applications?

I have an old MacBook Pro. By old, I mean abiut three or four years. I recently upgraded to Lion, but I have so many files that my system is forever showing thte rainbow spinner. I copied everything to an external hard drive, and would like to erase everything but my applications. Is there an easy way to do this?

Ok....Here we go.....
First open disk utility - then hit verify your disk.
Once that's done, verify your disk permissions - hit repair disk permissions if there are errors.
Once that's all done, restart your macbook.
Now you've done all those, delete all the files you've copied over to your backup/external drive.
If you've made folders for them, you can safely delete them. Only do this if you've made copies of those files in your external drive.
most of those files will probably in your document/movies/pictures folder. If you've copied them over to your external then you can delete them. Be sure you have copies before you delete them.
also delete anything in your download folder.
once you've done those, go to the appstore and download ccleaner. it is a small yet effective hard drive cleaner. no advance settings to mess around with. it will just delete your cache files and old log files.
good luck.
PS - to delete some of them you must move your mouse over it, tap once then keep your finger in the shift button then use your arrow keys to highlight them. once you've highlighed those files, right click on them then move to trash.

The Change time of the file is getting modified when no changes are made to the file content

While doing save operation of a MS-WORD file, (in my example "1M.doc" ) with client (Windows 8) and server(either Win 2008 R2 or Win2012 R2). Observing the following scenario.
After Renames are done(eg, xx.tmp renamed to 1M.doc) , all the file handles are being closed one by one.
When the xx.tmp file is closed, immediately followed by Create of 1M.doc, the LastWrite time values between Close and Create are same but LastChanged time values are different. The LastChanged and LastWrite times are noted from
the Close Response and Create Response packets.
No modification is done on the file between this last close and next create. So, why LastChanged time values are different for the file? We are observing this almost everytime with Win8- Win2k8R2/Win2012R2, but not observed
till now with Win8-Win2012.

Hi,
Is only word files have the issue? You could refer to the articles below to troubleshoot the issue:

How do I empty all the files in the "Downloads" folder ?

How do I empty all the files in the "Downloads" folder ? Can they all be deleted at once?

PS: when you look into the menu bar commands by mouse, you may note
there are keyboard shortcuts to perform the same tasks; such as they are.
*Edit> Select all* = uses 'Command + A' keys to do this, without mouse/menu.
And, it can be done quickly by keyboard. +(this will select all, for the next step)+
You would have to select the folder to be edited; yet there also are other key
board commands to select items, folders, applications, etc all without a mouse.
Once you choose items in a folder or other location, you can then use a
keyboard command to Move them to the Trash; from there, Empty Trash
with a three-key command; all without use of the mouse.
The keys to *Move to Trash* looks like it is 'Command + Delete'. Some key-
boards have two marked delete keys, so you may have to try both. The
+small delete key+ has an icon with right-facing x in a box.
The three keys, to *Empty Trash* via keyboard instead of menu bar/mouse
appear to be the combination of 'up-arrow, command, delete.'
Understanding some of the iconography of symbols used to indicate function,
or what keys to use, as indicated by icons instead of words, is not too hard.
There are articles and web pages which show various keyboard shortcuts.
Here's an example, from one of several I've bookmarked over a few years.
This one has images and shows what the key shortcut symbols mean.
• Mastering Keyboard Shortcuts: (from myfirstmac site)
http://www.myfirstmac.com/index.php/mac/articles/mastering-keyboard-shortcuts
• Mac OS X keyboard shortcuts:
http://support.apple.com/kb/HT1343
However, if you have anything you may want to keep before mass deleting, be
sure to move it into another folder. +re: The docked folders in Leopard+ 10.5 have
one .PDF in each, about each of the purposed folders. I haven't deleted mine yet.
{And I've added another folder into the dock near the Trash for my own alias items
and the original is on the hard disk drive (one user) or could be put into an account
folder so it would not have permissions or privilege issues with a second account.}
I'd thought about those 'keyboard symbols' after the first posting; but,
had to take an elder parent on several errands that took quite awhile.
PS: there probably are ways to use AppleScript and Automator to handle folder contents.
Good luck & happy computing!

After 10.8.3 update, time machine rebackups all the files in the home

Yesterday evening I have updated my MacBook Pro'11 from 10.8.2 to 10.8.3
Next time machine backup works for the whole night and now I can see that it rebackups the whole home user folder. It shows all the files in my home directory have been changed somehow. As a result, a huge amount of backup history is dropped on the time machine backup drive.
Is it okay? Why TM thinks my 350 GB of personal files have been changed after system update?

Ok, I didn't go in and check every file on the iMac last night when it did a full backup so will take your word for it. Doing this once with the new install seems reasonable to me, and with the large external drives I use is not a problem...well, except for the noise the drives make for such a long time will writing the backup
I am just happy knowing there is a good base for rebuilding the internal drive if I need it.

Is possible search all the files in one folder and get list all with the same extension.??

Hi,
I would like to get, if it is possible, do searching in one determinate folder and get all the files with the same extension, For example, Give the *.pou and get all the files on one list of the files in this folder and sub-folders...
If it is possible i would like to see any example.
Thanks a lot, Fonsi.

Hi Dennis,
I got your advise, I download the openG (i had problems, and downloading directly and install one to one).
Ok, i got but i have one problem, which i can't solve. I entry the promt to search and put the directory to save, later i push 'Do it' and it search the files, show the paths and number, then save in the folder and finally show the window , all ok!.
The problem is with the target path, when i want use the browse, it doesnt run properly. I want select one carpet, and it demands one file, i dont understand why??, i changed the options browse but it didnt work. Also i would like when i put one path if folder doesnt exist, directly create it and save the files, if exist copy it.
Thanks for all!. I attached the file in lv 7.1

I have a mac os 10.5.8, i want to upgrade to mac os snow leopard, can i keep all my files (documents, music on itunes) without backing up all the files first on a external device prior to the upgrade?

I strongly advise against upgrading the OS without first making a backup. Were something to go wrong you would lose all your files without the backup. See:
How to Install OS X Updates Successfully
A. Repair the Hard Drive and Permissions:
Boot from your current OS X Installer disc. After the installer loads select your language and click on the Continue button. Then select Disk Utility from the Utilities menu. 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 (4.0 for Tiger) and/or TechTool Pro (4.5.2 for Tiger) to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
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 external backup drive. Source means the internal startup drive.
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:
Purchase the Snow Leopard Retail DVD.
Boot From The OS X Installer Disc:
Insert OS X Installer Disc into the optical drive.
Restart the computer.
Immediately after the chime press and hold down the "C" key.
Release the key when the spinning gear below the dark gray Apple logo appears.
Wait for installer to finish loading.
E. If updating:
Download and install update(s)
Use Software Update, or
Download standalone updater(s).
