I have a mac running windows... no bootcamp or any other virtualization program... how can i go back to mac os?

A friend of mine played this cruel prank to me... he erased everything on my mac and installed windows 7 on it... at least he backed up my data... but whatever i just want to go back to mac and i've tryed everything and it doesnt work... please help!

Shootist007's advice relies on several assumptions. In order for that to work, you would need to have a recent Mac with Lion installed, or a somewhat recent Mac with Lion and the latest firmware update installed.
Also, there's probably an easier way. How did your "friend" (whose a** deserves a good kicking) back up your data? If he used Time Machine to back up the entire system, you can simply erase the hard drive and restore that system. See:
http://pondini.org/TM/14.html
If he made a "clone" of your old system, simply boot from the clone, erase your internal hard drive and clone everything back, using a tool like Carbon Copy Cloner or SuperDuper.
If reinstalling the system is necessary and you're not using Lion, you'll want to boot from your Mac OS X install disk by inserting it and restarting, then holding down the 'c' key until the Apple logo appears.
Edit: Oh, and you should start making your own backups. If you don't have any backups of your own, it's entirely possible that your "friend's" stunt could have destroyed valuable data. What happens if the drive he backed up to wasn't much good and fails before you get the data restored? You need to have a minimum of two complete, separate backups.

I have an old mpg video file, taken with a very early model "smart phone", that opens and plays fine in my newly "rebuilt" iPhoto library. I cannot open, edit it or share it with any other software. How can I fix it, to be able to do anything with it?

Detail:
I've recently purchaced a 4TB Thunderbolt drive to store my "vast" music and photo libraries. iPhoto had an issue reading the moved library, so I bought and used iPhoto Library Manager to "rebuild" it. Apart from much of the original data such as date taken & camera used etc, it appears to be working well. The aforementioned mpg video was taken some 9 years ago, using an early model "iMate" smart phone, and opens and plays fine on iPhoto, but I cannot open it with anything else, (I've tried iMovie, VLC players, Wondershare and Handbrake) nor can I share it. I just want to edit it, and share it with family.
Any help would be appreciated...

No - not iMovie, VLC, Wondershare or Handbrake... Quick time starts with a "CONVERTING", then I get
I've looked at the "tell me more" links, tried downloading some of the movie players there. I'm begining to think the file is corrupt.
Thanks for getting back to me again though - appreciate it...

Once you are in Recovery Mode, it's too late to do any backup. I am afraid you are going to lose your data.

By upgrading to 10.7.5 or later.
Upgrading from Snow Leopard to Lion or Mountain Lion
You can upgrade to Mountain Lion from Lion or directly from Snow Leopard. Mountain Lion can be downloaded from the Mac App Store for $19.99.
If you sign into the App Store and try to purchase Mountain Lion but the App Store says your computer is not compatible then you may still be able to upgrade to Lion per the following information.
A. Upgrading to Mountain Lion or Mavericks
To upgrade to Mountain Lion or Mavericks you must have Snow Leopard 10.6.8 or Lion installed. Purchase and download Mountain Lion or Mavericks (Free) from the App Store. Sign in using your Apple ID. Mountain Lion is $19.99 plus tax. The file is quite large, over 5 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.
     OS X Mountain Lion — System Requirements
     OS X Mavericks- System Requirements
       Macs that can be upgraded to OS X Mountain Lion
         1. iMac (Mid 2007 or newer) — Model Identifier 7,1 or later
         2. MacBook (Late 2008 Aluminum, or Early 2009 or newer) —
             Model Identifier 5,1 or later
         3. MacBook Pro (Mid/Late 2007 or newer) — Model Identifier 3,1 or later
         4. MacBook Air (Late 2008 or newer) — Model Identifier 2,1 or later
         5. Mac mini (Early 2009 or newer) — Model Identifier 3,1 or later
         6. Mac Pro (Early 2008 or newer) — Model Identifier 3,1 or later
         7. Xserve (Early 2009) — Model Identifier 3,1 or later
To find the model identifier open System Profiler in the Utilities folder. It's displayed in the panel on the right.
Are my applications compatible?
         See App Compatibility Table — RoaringApps.
B. Upgrading to Lion
If your computer does not meet the requirements to install Mountain Lion, it may still meet the requirements to install Lion.
You can purchase Lion by contacting Customer Service: Contacting Apple for support and service - this includes international calling numbers. The cost is $19.99 (as it was before) plus tax. It's a download. You will get an email containing a redemption code that you then use at the Mac App Store to download Lion. Save a copy of that installer to your Downloads folder because the installer deletes itself at the end of the installation.
     Lion System Requirements
       1. Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7,
           or Xeon processor
       2. 2GB of memory
       3. OS X v10.6.6 or later (v10.6.8 recommended)
       4. 7GB of available space
       5. Some features require an Apple ID; terms apply.

My friend accidently downloaded iOS6 for me and now i restored everything and its says i have to join the dev program but i dont want to, how to i restore to my old software before iOS6 come out?

Tell this "friend" and their parents that it is up to them to fix the device or buy you a new one.
Then as tonefox suggested, find a new friend.
In the future, your friends keep their hands off your devices... it's not that difficult of a concept.

Do as the manual says and restore the iphone

HT1414 My iphone asked if I wanted to update and I hit yes. It said to plug into ITunes so I did. My only option is to "restore". It didn't ask if I want to backup first. I don't have service on phone. How can I go back to "not" restoring?

I am going to buy either a Mac Air or Mac Pro Retina 8GB RAM and 256GB. And as I have to still run Windows I will install Parallels 9. As the Mac are both 64bit machines does that mean I need to install Windows 7 64bit ? And office pro 2013 64 bit too?

I am going to buy either a Mac Air or Mac Pro Retina 8GB RAM and 256GB. And as I have to still run Windows programs I will install Parallels 9. As the Mac are both 64bit machines does that mean I need to install Windows 7 64bit or just install 32 bit? (Going with Win7 as I hate Win8). And I will install Office Pro 2013 64 bit too or 32 bit or is that automatically selected by the underlying OS (I use Word, Excel and Access mainly for a membership database of a local club) ? I am not a power user so would appreciate advice on way to go

Again thank you. If I only use word, excel and access in the Win environment and Mac OS for email and safari for internet do I need anti virus software . Ie my connection to the world is mac only and I use office pro only to ruin the club, newsletters, membership database etc. and of course anything I do there can drag/drop to the mac environ to email. That's my understanding anyway. Next will my existing .pst file copy directly into mac mail or do I have to runs translator as I recall reading something about that ages ago when I started thinking Mac

HT1533 How can I switch back to Mac OS X from Windows 7 Bootcamp?

I'm having problem switching back to Mac OS on my Macbook Air. It's currently running Windows 7 bootcamp without a Mac OS installed with it. I tried booting up on Mac OSX installer disc (Snow Leopard) on the external CDROM drive but it boots to Windows instead. I tried the Boot Camp Control Panel on Windows and Restart to Mac OS X but it could not find an OS X intalled and I tried changing the startup disc to the installation disc on the CDROM and restarted but still goes to Windows.
Please HELP!
Thank you.

The MBA did not ship with an OS on DVD because they don't have an optical drive. There are two kinds of OS disks - commercial release, which for Snow Leopard is 10.6.3 I believe, and machine specific. If your SL disk is gray it isn't going to boot your MBA because it isn't made for the MBA. If your SL disk has a cat on it look at what specific version it is. As I said, I think it is 10.6.3 and while I wasn't able to find out what specific OS version your MBA shipped with, I'm pretty sure it was a version later than 10.6.3 and if I'm right your disk isn't going to boot the computer. You'll need to either contact Apple for a valid replacement installer or find someone with a Mac who can make a valid installer on a USB drive or DVD.

After upgrading to mountain lion i keep getting an error message saying my startup disc is full. it shouldnt be full because there is barely anything on there and i was running windows with bootcamp prior to this with no issues

after upgrading to mountain lion i keep getting an error message saying my startup disc is full. it shouldnt be full because there is barely anything on there and i was running windows with bootcamp prior to this with no issues. my computer now freezes and programs close randomly. The usual command for opening windows with bootcamp doesnt work. once in restarted my computer after it froze and it rebooted in windows automatically. i really just want to know if there is a way to take the upgrade off my laptop because it is very annoying.

Hi Memalyn
Essentially, the bare issue is that you have a 500GB hard drive with only 10GB free. That is not sufficient to run the system properly. The two options you have are to move/remove files to another location, or to install a larger hard drive (eg 2TB). Drive space has nothing to do with SMC firmware, and usually large media files are to blame.
My first recommendation is this: download and run the free OmniDiskSweeper. This will identify the exact size of all your folders - you can drill down into the subfolders and figure out where your largest culprits are. For example, you might find that your Pictures folder contains both an iPhoto Library and copies that you've brought in from a camera but are outside the iPhoto Library structure. Or perhaps you have a lot of purchased video content in iTunes.
If you find files that you KNOW you do not need, you can delete them. Don't delete them just because you have a backup, since if the backup fails, you will lose all your copies.
Don't worry about "cleaners" for now - they don't save much space and can actually cause problems. Deal with the large file situation first and see how you get on.
Let us know what you find out, and if you manage to get your space back.

I have a PC running Windows XP (yes an antique) with CS3 Photoshop and InDesign and lightroom 2 (yes all antiques). I have acquired a PC running Windows 7 with no programs. I also have a MacBook pro with full CS5 suite. The programs were already loaded with I got it as a gift. Question 1. If I find serial numbers used to download programs to the old PC, can those CS3 programs be put on the newer PC. Question 2. I really want to put CS5 suite on PC machines. Is that possible? Especially since my MacBook is showing some hard drive problems.

You should be able to get the CS3 programs installed and running on the new pc since CS3 is spec-ed for Windows 7 Service Pack 1. Downloading the programs does not require a serial number. You can find them here: Download CS3 products but you will need the serial number to activate the programs. You might be able to find that thru your Adobe account online.
You will not be able to install the CS5 Mac version on a PC and you won't be able to trade it to a PC version either due to it being an older version. Trades are allowed only for the latest version (CS6)

HT5639 Will running windows with bootcamp effect my macbook pro's overall speed

Will running windows with bootcamp effect my macbook pro's overall speed ?

Welcome to Apple Support Communities
In some cases, there may be slowness in OS X because of the lack of free space. However, you shouldn't note this and in most of cases, performance is the same in Windows and OS X after installing Windows, more in the case of a MacBook Pro with Retina display.
The only thing you have to worry is to give Windows the necessary space. The MacBook Pro with Retina display hasn't got a lot of storage
