How to erase my HD and run my imac once again?!

ok...I have no access to Mac desktop or disk utility with command+R I have no DVD of mac softwere to restore it. I can only acces single user mode only and Fsck -fy doesn't do anything. oh and I have windows bootcamp so one partition is has windows. So....can I do anything to erase everything and start my mac computer from the very beginning??!?!?!

If your Mac is new enough to have come pre-installed with OS X Lion or Mountain Lion or Mavericks, you should be able to restart into Internet Recovery (Command+Option+R). Hold those keys until you see a spinning globe. You will need an internet connection to do this. This will boot into Apple's servers for Recovery. From there, you should be able to use Disk Utility to repartition your internal drive into one partition and label it Macintosh HD. Then you should be able to reinstall the most current version of the OS X that came pre-installed (e.g. Lion 10.7.5, Mountain Lion 10.8.5, Mavericks 10.9.4).

How to erase all datas and factory reset in iMac

Boot into the Recovery HD (restart holding down Command+r). Launch Disk Utility and erase the drive (all data will be gone forever so make sure you have a reliable copy of any valuable data). Quit out of Disk Utility when formatting is complete and select re-install OS X (you'll need an Internet connection).

In Preview, when I add text annotations to my PDF (lecture note slides), they look fine until I close it and reopen it, and then they are rotated 90 degrees. How do I fix this and keep it from happening again?

I have the same problem with lectures slides.
Furthermore, sometimes the text box, when doube-clicking, turns the text into a one-liner. Causing the text box to sometimes get 3. times wider than the pdf itself.

By pressing [cmd + I] the Inspector opens up and clicking on the rightmost tab 'Annotations' you should be able find those Annotations again. I do this regularly to find the empty annotations I accidentally create while clicking through slides.

Hello Errappa,
Thank you for using Apple Support Communities!
I was thinking that it would be a good idea for you to call our Account Security team about what may be happening with the account.

New Computer..how to get Ipod up and running

my old computer broke down and I have a new one. No access to old computer. How do I get my ipod up and running with new comp? I get a message saying my ipod is synched with another computer (the broken one)?

Synching to the new computer will wipe everything off the iPod.
If you have it enabled for disk use, mount it as a drive then copy off all of the hidden folders into your new iTunes. The hidden files will have nonsense names, but all the music is there, and iTunes will rename everything if you have it set to copy to your new library.
Otherwise, try these links from another thread (thanks PT):

How to get Adobe up and running?

This download then go back and sign some agreement is stupid and it is not evident that there is anything to sign. I have clicked on agree several times and am still unable to get it to work. This is a Macbook Pro computer and I'm tired of not being able torun PDF's. Please help me get this up and running. there has to be a better way to go about this. Michael Allison

Not sure what you mean by "sign agreement"; do you mean accept the license agreement? To do that you must open Reader by itself and accept the EULA, before you can use it online.
If I misunderstood, please clarify.

How to Erase all Content and Settings and keeping IOS 7.06?

I'd like to participate the iPhone 5 Sleep/Wake Button Replacement Program, however than I'll have to Erase all Content and Settings and I'm afraid I'll loose IOS 7.06.

If this is anything like standard warranty service, the unit you get back will be totally refurbished, which also means having it updated to the latest iOS release. The caveat in the program description hints this:
Note: If your iPhone 5 has any damage such as a cracked screen which impairs the replacement of the sleep/wake button, that issue will need to be resolved prior to the sleep/wake button replacement. In some cases, there may be a cost associated with the repair.
Also important to ask, does your phone have a faulty button in order to qualify for the repair? They also clearly state:
Apple will replace the sleep/wake button mechanism, free of charge, on iPhone 5 models that exhibit this issue and have a qualifying serial number.

How do I delete history and bookmarks on iMac?

On the iPad, I could use Settings to delete history, but there s no such function on iMac. How do I delete bookmarks and Top Hits and history altogether?

Welcome to Apple Support Communities
To do it in OS X, open Safari and go to Safari menu (on the menu bar), so you will find an option called "Reset Safari" or something similar. Another way of removing history is to go to Safari menu -> Preferences -> Privacy, and press "Delete All Web Site Data".

How should I treat a by product which is once again used in Production

Hi Gurus,
I am working in a make-to-stock scenario in discrete manufacturing industry. There is a by product produced at the end of manufacturing process. My approach to this was I created the BOM with -ve quantity of the by product. I thought I use movement type 531(or 262) for by product. But now the matter is that this by product is once again is consumed in foundry. So I am not able to capture that part in controlling.
Can any expert please through some light on this?
Thanks and Regards,

Hi
Define a std cost for this by product through MR21 or CK11n
1. Maintain -ve qty in BOM
2. When you execute std cost for the header material, cost for by product recovery would get adjusted in the std cost
3. During production, when you do GR/GI, your by product would come into stock at the same std cost
4. In foundry process, when you issue this by product, it will be issued at same value
Regards
Ajay M

How is the code compiled and run?

Hi,
im wondering how this code is interpretet/run by flash as3.
Lets say i have a for loop:
for ( var i:Number = 0; i < 12; i++)
runStep1();
runStep2();
runStep3();
Does the as-code run top to bottom and every method runStep1,
runStep2, runStep3 is run in a sequence or does the for-loop just
rush through the methods and doesnt bother if the methods are
totally executed?
//Criss

Hi --
I agree with you on the way Actionscript behaves -- it
definitly doesn't
execute in a way you would expect. One way to work around
this issue (if
possible) is to call one function from the end of another,
for example:
for ( var i:Number = 0; i < 12; i++)
runStep1();
function runStep1() {
runStep2();
function runStep2() {
runStep3();
This appraoch won't always work if you don't always want step
2 to run after
step 1, etc. but it is one approach to this issue.
