I have installed a OSX 10.7.5 and I want to install a clean copy of OS X mountain Lion on my mac.

I want to install a clean copy of Mountain Lion not an update from my current version which is 10.7.5.
I do not want to keep my old program files. I already have my personal info backed up.
Thanks

If you don’t have it yet, get Mountain Lion from the Mac App Store but do not install it yet (orredownload it if you did install it)
Create a bootable install drive for OS X Mountain Lion, make one manually with a USB drive oruse the LionDiskMaker tool to automate the process with a USB or DVD
With the boot installer drive connected to the Mac, reboot and hold down the Option key
Choose the “Mac OS X Installer” startup volume from the boot menu
Select “Disk Utility” and choose the hard drive you wish to format, click the “Erase” tab, and then pull down the “Format” menu and select “Mac OS Extended (Journaled)” as the type, name the drive if you wish
Click the “Erase” button and let the drive format – this is the point of no return
When finished, quit out of Disk Utility and now select the “Install Mac OS X” option from the menu
Choose your freshly formatted hard drive and install Mountain Lion
When the Mac reboots you will have a clean installation of Mac OS X 10.8 to work with.
I did this last week and its working fine

Open the Users & Groups pane of System Preferences and disable automatic login, and then go into the Security & Privacy pane and set the computer not to log out after a period of inactivity.

Open the Mac App Store on the other Mac and in the Quick Links sign into your account. See if the Mountain Lion purchase is among hidden apps in the iCloud area of your account info.

My Mac is a OSX 10.5.8 and i want to upgrade to Lion v10.7.2 Do I have to also get Snow Leopard? Can the be purchased together?

Yes you have to purchase Snow Leopard first. Once you have it installed then update it to 10.6.8 using the 10.6.8 Update Combo. Once you have updated and thorougly tested your system then purchase the Lion upgrade from the Mac App Store and follow the on-screen prompts.
At the very minimum make sure your computer meets the System Requirements for Lion and make sure you have all your applications up-to-date. As you may (or may not) know PPC based apps will NOT run under Lion so please check your apps to see that they will run under Lion. Please look at the article link below for instructions on how to tell if they will or not.

I don't have the option of installing a clean copy of Snow Leopard

I'm new to Mac and have been exploring different programs that would fulfill the same functions as the programs I had been using on Vista. Unfortunately, my computer got a little wonky somewhere along the way and I want to remedy it by erasing the hard drive and installing a clean copy of Snow Leopard. I've looked in my owner's manual as well as several websites online. They all tell me to select something either from a tab or an Options menu but there isn't one. When I reach the Select Destination window, I have the option to customize what is installed (i.e. Quicktime, Rosetta, etc.), go back and continue. Is it not possible or something???

it's possible but there is likely no need to do this. what exactly is wrong with your computer? a simple reinstall of snow leopard on top of your current system will cure many ills and will preserve your data and applications. and many problems can be solved without reinstalling at all.
but if you insist on doing a wipe and install boot from the SL install DVD and start disk utility from utilities menu at the top. erase your hard drive using the erase tab in disk utility. then quit disk utility and proceed with the install. and if you do reinstall I suggest you back up your data first. otherwise it will be completely wiped when you erase your hard drive. and you should always back up anyway.

I have my new HD in a USB enclosure connected to my MacBook Pro and I want to put a fresh copy of Mountain Lion on it. But I do not have an install DVD as I got ML as a download from the App Store. What do I do?

I have my new HD in a USB enclosure connected to my MacBook Pro and I want to put a fresh copy of Mountain Lion on it. I'm told that I need to boot from the Installation Disk to start. But I do not have an install DVD as I got ML as a download from the App Store. Can I download ML from the App Store again, but this time directly to my new HD?

Create a data recovery/undelete external boot drive
You can also use Carbon Copy Cloner to clone your present setup to it and boot from it.
Most commonly used backup methods
However, SOME external enclosures are not bootable, you will soon find out.

I downloaded Mac OS X Lion and when I go to install, it says file cannot be verified, may have been corrupted during download. How do I determine if it is corrupt and how do I get a clean copy of Lion, since I have already paid for it?

Download again, move the existing file out of the applications folder first.

I bought the CD of iWork's and have installed pages from it - to use version in Lion do I have to buy the app?? If I do, do I have to delete the other pages??

All you need to do is run Software Update to make sure you have the iWork 9.1 update. It will update your existing installation of the three applications. If you're not running the latest versions & Software Update says your software is up to date, make sure the applications are where the installer initially put them. The updaters are very picky. If the location is not where the updater is programmed to look or if the folder doesn't have the name the updater looks for, it will not work. The applications cannot be renamed or moved. Even if you think you'll never need all three of the applications, you cannot delete any. They must be in the iWork '09 folder in Applications. That iWork folder must be named iWork '09. If it doesn't have the '09 Software Update won't find them & the updaters won't work.

After installing Mountain Lion on my Mac I have no Internet. Safari doesn't work.

After install Mountain Lion on my Mac I don't have Internet. Do not know what has happened.

Try a PRAM reset and an SMC reset.

I have bought a new imac late 2012 and I want to wipe clean my 2008 mac and install Mountain Lion on the old computer for my kids to have

I have bought a new imac late 2012 and I want to wipe clean my 2008 mac and install Mountain Lion on the old computer for my kids to have.
What do I need to do?

Boot your Mac from the System Install DVD that came with it, and erase the HD using Disk Utility. Then, reinstall the OS from the disc. Give the disc to your kids since it must always accompany the Mac it came with.
After the OS installation is complete and the Mac restarts to begin its new owner setup procedure, just shut down the Mac. Your kids can take it from there.
If you purchased Lion or Mountain Lion from the App Store, you cannot transfer it. The Apple ID you used to purchase it is required to maintain and / or reinstall the OS. Unless you want to supply your own Apple ID to your children for their use, they must purchase their own copy of Mountain Lion using their own Apple ID.
If they do not already have an Apple ID and you want them to have Mountain Lion, you will need to create one on their behalf. This does not change the above procedure - just give them the Apple ID and password you create in addition to the Mac and its discs.

Hi, I have a PPC Running OSX 10.5.4 and I want to delete the User "Guest"and "Shared"Folders on my HD, they won't let me change the permissions and I keep getting errors that say the permissions should be 0 and are 501 and having files i can't delete that

Hi, I have a PPC Running OSX 10.5.4 and I want to delete the User "Guest"and "Shared"Folders on my HD, they won't let me change the permissions and I keep getting errors that say the permissions should be 0 and are 501 and having files i can't delete that go on and on ad infinitum... I think it's a virus or a corruption? Can anyone tell me or help me and let me know what I'm dealing with here or wether I'm mistaken and should leave it alone?
I'd appreciate it.
Thanks,
Matt

Why do you want to delete those? What have you done so far to do that?
I doubt that Mac has a virus. On the other hand, your attempts to deleted those folders may have caused corruption.
Two other comments:
1) Is there a reason that Mac hasn't been updated to OS X 10.5.8?
2) You've been misled by the poor field labeling on this Web site into trying to type your entire post into the "subject" field. In the future, just put a short summary of your post into that field.

I have an iMac (OSX 10.9.2) and a Macbook (same). I want to copy photos from one to the other. how?

I'm sorry. I got a little off-the-wall there.
I want to have the same iPhoto files on both machines. A few days ago I spent several hours swapping photos back and forth until I had one event with identical picture files on both. Yesterday I scanned some old photos into the Macbook. Today I wanted to copy them to the iMac. I could not remember what I had done a few days ago, so I spent a couple of frustrating hours trying to either remember or find another way, to no avail. I have no idea what I did right before; I only recall that it was pretty easy.
I didn't write anything down. I used to do that, but what I do is so intermittent that by the time I want to copy pictures again either (a) the app has been updated and the old way doesn't work (b) I've lost the paper with the notes on it or (everything seems fine but it just doesn't work. So I gave that up.
Yes, I do want both iPhoto libraries to be the same. The Macbook is the one with the scanner and I download from my camera on the iMac, so I need to be able to move photos from one to the other, I think.

Buy Mountain Lion on friends mac, install on my wiped MBP?

Can I buy Mountain Lion on a friends computer under MY apple id and install it to a completely wiped mac book pro? I would do it by using the wireless download/install when lion in bought under my apple id (if that is possible). When I run reinstall it asks for mountain lion and my snow leopard cd will not work regardless of attempts.

You said that he is running Leopard, and the App Store needs Snow Leopard, so he has to upgrade to Snow Leopard.
First, open  > About this Mac and check Version. If it's 10.6, he has Snow Leopard, so he doesn't have to purchase it. Check if the computer is supported > http://support.apple.com/kb/sp575 Buy Snow Leopard > http://store.apple.com/us/product/MC573/mac-os-x-106-snow-leopard Then, make a backup, insert the DVD and upgrade.
The disc will install 10.6.3, so go to  > Software Update to update to 10.6.8, which has the App Store, so login with your Apple ID and purchase Mountain Lion. Note that you will only be able to purchase Mountain Lion if his Mac is compatible > http://www.apple.com/osx/specs
Also, he can't use the Mountain Lion copy that you downloaded onto it because it's registered to your Apple ID
