Why does my computer revert back to old setting on restart
i have an imac running 10.84. whenever i restart my machine everything resets to an old setting - iI cant seem to effect a permanent change when I want to - for instance if I remove apps from thedock and even delte them they reappear at next restart. If i delete an old email account it reappears at next restart. So do all my bookmarks in safari - I cant add a new one or delet an old on a permanent basis . Its driving me nuts! I have turned time machine off thinking it could be that but there is no difference. I wonder if its to do with icloud backup somehow but cant figure out how . Any help much appreciated!
Back up all data.
This procedure will unlock all your user files (not system files) and reset their ownership and access-control lists to the default. If you've set special values for those attributes on any of your files, they will be reverted. In that case, either stop here, or be prepared to recreate the settings if necessary. Do so only after verifying that those settings didn't cause the problem. If none of this is meaningful to you, you don't need to worry about it.
I've tested these instructions only with the Safari web browser. If you use another browser, they may not work as described.
Step 1
If you have more than one user account, and the one in question is not an administrator account, then temporarily promote it to administrator status in the Users & Groups preference pane. To do that, unlock the preference pane using the credentials of an administrator, check the box marked Allow user to administer this computer, then reboot. You can demote the problem account back to standard status when this step has been completed.
Triple-click anywhere in the following line on this page to select it. Copy the selected text to the Clipboard (command-C):
{ sudo chflags -R nouchg,nouappnd ~ $TMPDIR.. ; sudo chown -R $UID:staff ~ $_ ; sudo chmod -R u+rwX ~ $_ ; chmod -R -N ~ $_ ; } 2> /dev/null
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window (command-V). You'll be prompted for your login password. Nothing will be displayed when you type it. You may get a one-time warning to be careful. If you don’t have a login password, you’ll need to set one before you can run the command. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
The command will take a noticeable amount of time to run. Wait for a new line ending in a dollar sign (“$”) to appear, then quit Terminal.
Step 2 (optional)
Take this step only if you have trouble with Step 1 or if it doesn't solve the problem.
Boot into Recovery. When the OS X Utilities screen appears, select
Utilities ▹ Terminal
from the menu bar. A Terminal window will open.
In the Terminal window, type this:
res
Press the tab key. The partial command you typed will automatically be completed to this:
resetpassword
Press return. A Reset Password window will open. You’re not going to reset a password.
Select your boot volume ("Macintosh HD," unless you gave it a different name) if not already selected.
Select your username from the menu labeled Select the user account if not already selected.
Under Reset Home Directory Permissions and ACLs, click the Reset button.
Select
▹ Restart
from the menu bar.

Why does LabVIEW 2009 revert to the old icon editor?
Hi,
I have noticed that sometimes when I am trying to edit the icon in LabVIEW 2009, I get the old style icon editor from LabVIEW 8.5 days instead of the more advanced new one with layers, gliphys, etc. Once the old style editor shows up, there doesn't seem to be a way to go back to the advanced editor. Has anyone seen this behaviour? I have version 8.5 of LabVIEW still installed, should I remove it? Do I need to restart my computer?
Thanks.
BobHere are some of the errors I see ...

Why does my computer keep disconnecting from my wifi?
Why does my computer keep disconnecting from my wifi?
Some users with various Wi-Fi problems have reported that they were given the following instructions by Apple Support, sometimes with success. After completing the procedure, you'll have to recreate all your settings in the Networkpreference pane. Make sure you know how to do that before you begin. Taking screenshots of the preference pane may be helpful.
Step 1
Back up all data.
Triple-click anywhere in the line below on this page to select it:
/Library/Preferences/SystemConfiguration
Right-click or control-click the highlighted line and select
Services ▹ Reveal
from the contextual menu.* A folder should open with an item named "SystemConfiguration" selected. Move the selected item to the Trash. You may be prompted for your administrator password. Reboot and recreate the network settings.
*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combinationcommand-C. In the Finder, select
Go ▹ Go to Folder...
from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.
Step 2
Reset the System Management Controller.
Step 3
Reset the PRAM. -
Why does the "Computer Name" sometimes change?
Not a big deal, just curious, why does the "computer name" sometimes change?
The name will be the same, but it will add a number....2,3,4...I always change it back so it doesn't have a numeric value next to it, but just wondering why it happens.
Thanks.Can also occur after your computer is put to sleep and then wakes back up or after your computer is force quit and immediately restarted. Sometimes the router 'believes' the computer is still connected when it actually isn't. When that computer re-establishes a connection the router 'tells' the computer that a computer with that name already exists so it has to change its name. By default a computer running MacOS adds a number (or increments its number) when this happens.

After making a new Illustrator file from an old one, then saving it as a pdf, the new Illustrator file reverts back to old one. I have been using the pdf to make the Illustrator file again (luckily I've saved it as editable) but I don't always want to add this extra procedure. Does anyone have this issue or any clues on how this happens and how to fix the problem?
when you made your changes and then saved as, you saved your changes to a new file. your original file closes without saving and the open file in illustrator is the new one (in your case the PDF).
evertime you save as you are making a new file without affecting the old file.
you should first save your changes and then save as. but after the save as, the opened file will no longer be the original file.
if you do a Save As Copy. then you will be saving a new file which will be closed and your original file will remain open. -
Why does Calendar keep reverting from full screen each time I exit the app?
I'm using a 2014 Macbook Air. It's running Yosemite.
Why does Calendar keep reverting from full screen each time I exit the app?
On my older Macbook at work, calendar stays full screen whether I exit the app or restart the computer (similar to Mail - which is staying in full screen on both computers).
Please help me adjust settings so I don't have to keep putting Calendar into full screen.

Got to end of trial period for Adobe reader XI and cannot revert back to old version or install another version b/c it says I have a newer more functional version, so now I've got no reader at all and cannot fix. Any ideas how to overcome this?.
YOu need to be clear about the products you are using, so we can help you. In particular there is no trial of Adobe Reader, it is free and keeps running. Sounds like you are using some versions of Acrobat - which?
YOu must properly uninstall the trial, don't just delete files or you may get a mess impossible to recover. -
Why does my computer display a spring coloured wheel that stops me from doing anything
Why does my computer display a spinning coloured wheel that stops me from doing anything, the only way to get rid is to switch off and reload...
These instructions must be carried out as an administrator. If you have only one user account, you are the 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 and start typing the name.
Step 1
For this step, the title of the Console window should be All Messages. If it isn't, select
SYSTEM LOG QUERIES ▹ All Messages
from the log list on the left. If you don't see that list, select
View ▹ Show Log List
from the menu bar at the top of the screen.
In the top right corner of the Console window, there's a search box labeled Filter. Initially the words "String Matching" are shown in that box. Enter "BOOT_TIME" (without the quotes.)
Each message in the log begins with the date and time when it was entered. Select the BOOT_TIME log message that corresponds to the last boot time when you had the problem. Now clear the search box to reveal all messages. Select the ones logged before the boot, during the time something abnormal was happening. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message by pressing command-V.
For example, if the system was unresponsive or was failing to shut down for three minutes before you forced a restart, post the messages timestamped within three minutes before the boot time, not after. Please include the BOOT_TIME message at the end of the log extract—not at the beginning.
If there are long runs of repeated messages, please post only one example of each. Don’t post many repetitions of the same message.
When posting a log extract, be selective. A few dozen lines are almost always more than enough.
Some private information, such as your name, may appear in the log. Anonymize before posting.
Please don't indiscriminately dump thousands of lines from the log into this discussion.
Please don't post screenshots of log messages—post the text.
Step 2
In the Console window, select
DIAGNOSTIC AND USAGE INFORMATION ▹ System Diagnostic Reports
(not Diagnostic and Usage Messages) from the log list on the left. If you don't see that list, select
View ▹ Show Log List
from the menu bar.
There is a disclosure triangle to the left of the list item. If the triangle is pointing to the right, click it so that it points down. You'll see a list of reports. A crash report has a name that begins with the name of the crashed process and ends in ".crash". A panic report has a name that begins with "Kernel" and ends in ".panic". A shutdown stall report has a name that ends in ".shutdownstall". Select the most recent of each, if any. The contents of the report will appear on the right. Use copy and paste to post the entire contents—the text, not a screenshot. It's possible that none of these reports exists.
I know the report is long, maybe several hundred lines. Please post all of it anyway.
If you don't see any reports listed, but you know there was a crash or panic, you may have chosen Diagnostic and Usage Messages from the log list. Choose DIAGNOSTIC AND USAGE INFORMATION instead.
In the interest of privacy, I suggest that, before posting, you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if it’s present (it may not be.)
Please don’t post other kinds of diagnostic report—they're very long and rarely helpful. -
Revert back to Old status if ticket results in error..
Go to transaction CRM_DNO_MONITOR. Select a ticket for display. Let the status of the selected ticket be NEW. Now input all information in standard and screen Enhancement(By EEWB) input fields. Now make an action 'assign' After saving the status will change to Assign. But at the same time there is a screen validation dependant on the status change from New to assign. According to that the validation happens in PBO event of the Screen enhancement where we are getting Old as well as new status. Here it is found that remarks in long text is to be entered while this perticular status change is happening. but the same is not done. So there is a error message that 'you have not entered remarks general'.
When the error occurs the status should change back from assign to New. Since user may go out of ticket without saving Or the error pop up will throw you out of ticket. When the user again opens the same ticket, the status of the ticket is Assign. So there should be a BADI or open routine available after before the update to database happens for the new status. Also this enhancement should happen after Screen Enhancement(By EEWB)'s PBO event. So validation of screen enhancement can be carried out.
In short please provide enhancement or routine or function module which can revert back to old status.Go to transaction CRM_DNO_MONITOR. Select a ticket for display.

Authorization and Deauthorization
See iTunes Store- About authorization and deauthorization for Macs.
See How to Authorize or Deauthorize iTunes | PCWorld for Windows.
In iTunes you use the Authorize This Computer or De-authorize This Computer option under the Store menu in iTunes' menubar. For Windows use the ALT-S keys to access it.
More On De-authorizing Computers (contributed by user John Galt)
You can de-authorize individual computers, but only by using those computers. The only other option is to "de-authorize all" from your iTunes account.
1. Open iTunes on a computer
2. From the Store menu, select "View my Account..."
3. Sign in with your Apple ID and password.
4. Under "Computer Authorizations" select "De-authorize All".
5. Authorize each computer you still have, as you may require.
You may only do this once per year.
After you "de-authorize all" your authorized computers, re-authorize each one as required.
If you have de-authorized all computers and need to do it again, but your year has not elapsed, then contact: Apple - Support - iTunes - Contact Us. -

Change Outlook Calendar background color but its reverts back to old on restart
Dear Support,
I am trying to change Outlook Calendar background color but its reverts back to old on restartHi,
Let's take Outlook 2013 for example, go to FILE tab ->
Options -> Calendar -> Display options
-> Select the Default calendar color and the checkbox for
Use this color on all calendar ->
OK.
In case the Navigation Pane is corrupted, we may try starting Outlook with the switch "/resetnavpane":
Press Win + R and type “outlook.exe /resetnavpane” in the blank box, then press Enter.
I hope this helps.

How do I transfer from time machine adobe lightroom programme to my girlfriends computer (backed up on my hard drive via time machine) with out setting up my full desktop - i need it until i can afford a new computer to restore my old set up completely.
Any ideas, I can access files - i.e. jpegs of old work, but can't edit new photos...
PIf you have a license for Lightroom, you should be able to reinstall it from an installer disc or re-download it from Adobe after explaining the situation and clarifying the license issues. Either will be simpler than trying to extract and install it from a TM backup of a different Mac, I think. If it's anything like other Adobe products, it has bits and pieces all over the place that you'll have to find and put in their right places on your girlfirend's Mac.

Why does my computer freeze and curser dissapears?
Why does my computer freeze and curser dissapears?
I had a similar problem after upgrading to Windows 7. The problem seemed to be that there was a dialog box that opened
that was not visible on the screen and it was blocking the print completion. Try this. Open the Adobe PDF Printing Preferences and clear the field "Rely on system fonts only, do not use document fonts." When I did that it solved my problem.
The unseen dialog box seems to be the fault of Windows 7, in my opinion.
