Clean install of Lion on MacBook Pro

Hello - I have been using Lion for a while now, with no problems, but am now having permission problems with such actions as emptying trash, downloads, upgrading certain apps, using Dropbox, etc. I think it has something to do with my user settings, but have tried in as many ways to repair this, to no avail. I am backing up my files on a Time Capsule - and the only things I am really wanting to keep are my iTunes files and my iPhoto files. (I upgraded from Snow Leopard to Lion.)
My questions:
1. Once everything is backed up to TC, what is the best way for me to do a clean install of Lion?
2. How do I then go about reinstalling my apps/files (iTunes, iPhoto, movie files, documents, etc)?
Also, is there anything one needs to be aware of when installing Lion in regards to user name, administrator, etc?
Thanks in advance.

New hard drive, clean install of Lion, but MacBook Pro is still freezing

Hi everyone,
Even the folks at the Apple store don't seem to know what's going on with my MacBook Pro.
My hard drive crashed a few weeks ago. I bought a Western Digital Scorpio Blue and replaced it myself. The MacBook didn't seem to like it (lots of freezing, going really slow, etc) and so, after reading online that many MacBook Pro users did not like the WD Scoprio Blue, I returned it and bought a 320 GB Hitachi. Before replacing the WD drive with the Hitachi drive, I used SuperDuper! to make my external hard drive a clone of the WD hard drive. I replaced the WD with the Hitachi, booted from the external, and then restored all my stuff to the Hitachi. The computer still didn't work so well, so I did a zero-out erase and a clean install of Lion. I dragged my files over individually (only about 100 GB of word documents, music, and photos). For the first two days, everything worked perfectly. Then I started getting these error messages:
Word: Word cannot save or create this file. The disk may be full or write protected. Try one of the following. *Free more memory. *Make sure that the disk you want to save the file on is not full, write-protected, or damaged.
Chrome: Your profile could not be opened correctly. Some features may be unavailable. Please check that the profile exists and you have permission to read and write its contents.
Dragging files to trash: The operation can't be completed because an unexpected error occured (error code -50).
Fireforx: Close Firefox. A copy of Firefox is already open. Only one copy of Firefox can be open at a time.
In addition, the computer kept freezing. I also had problems with Mail and iTunes. Disk verify, permission verify, S.M.A.R.T. utility all said that the hard drive was working fine though.
So, I brought the computer to Apple. They did a zero-out erase, reinstalled Lion, and did what they called a "software repair". They said it should work fine. I just got home from the store, booted up the computer, and it's barely working. All sorts of error messages, safari won't work, it keeps freezing, and I was only able to open disk utility once. I verified disk, and it came up with no problems. I verified disk permissions, and when I tried to repair disk permissions, it kept saying it was "unable" to.
I don't know what it could be. It's not the hard drive...I've run disk utility, S.M.A.R.T., and an app that checks the hardware associated with the drive. All of these programs say the hard drive is absolutely fine. I've also reset PRAM. Another thing worth noting is that I'm currently booting/working off of my external, and it works absolutely perfectly.
Any ideas? One of my friends suggested I go back to Snow Leopard, but I don't see what difference that would make. Please help! Anything would be very much appreciated! Thanks!!

The theory is that you have a weak bit in one of the modules, and sometimes (rarely) it flips over. The trick is to try and catch it.
If you move the modules, the weak bit will be at a different Address in memory. Different things will be loaded into the word with the weak bit, and the symptoms may be different.
It may not do anything at all. But it is so easy to try, it is worth a shot.
On a multi-module memory, you need to keep your wits about you when doing this, or you put them back the way they were originally. So you should pick a direction and always move them your "regular" direction.

How to clean install os x on macbook pro late 2013 using usb (offline) (without recovery direct download)

hi,
Im trying to clean install OS X from last month using inbuild recovery partition method. Due to slow internet connection Im unable to complete the installation. I tried many times using this intallation process but it failled to complete the installation. My internet connection is steady but due to "time out" the whole installation process is skiping. So Im not able to use my brand new macbook pro late 2013 from last month beginning. Please provide an alternative solution to install os x.

For several years now, Apple has acted as if everyone on the planet has high speed Internet access. That is obviously not the case for many people, and for them installing or reinstalling any OS X version since Lion has been a problem.
I can only suggest that you take your MacBook Pro to a location that has a faster, publicly accessible Internet connection and download it there. An Apple Store would be ideal, but if that is not an option, a public library may offer high speed Internet, as do many hotels, coffee shops, or similar locations where you may have to pay a small fee.
When the download completes, you can copy the Install OS X Mavericks icon to another folder or an external storage device such as a flash drive, where it will remain available to use again, as often as you wish. Do that before proceeding with the Mavericks upgrade, otherwise the installer will erase the file.
The installer icon resembles the following
(Launchpad)
The following will also appear in /Applications:
Copy that to another location, such as Documents, by holding an option key while you drag it there.
Of course, every time Apple releases an OS X update you will need to download another, rather large file.

Installing Mountain Lion on MacBook Pro i5 Early 2011

Hi!
I have a MacBook Pro early 2011 i5 13" with 4GB RAM. I'm still running it on Snow Leopard. I'm just wondering if anyone has installed Mountain Lion on a similar machine and can fill me in on the performance after installing Mountain Lion. Is it ok to switch to Mountain Lion or will it slow the machine down significantly? Thanks!

Before you upgrade, make sure all your software supports it based on post July, 25, 2012 reports on
http://roaringapps.com/apps:table
Reports prior to this date are unreliable, as they are likely with beta releases of Mountain Lion to developers. Other pitfalls to realize include:

OS clean install interupted on 2011 Macbook Pro G4. Now computer not booting up

I have a Mac Book Pro G4 (Early 2011) I was in the middle of doing a Yosemite clean install and I I took the memory stick out before the OS finished because I couldn't cancel and I thought it was hung-up. Now it doesn't power up. I get the attached message!
After this message it just restarts, then message appears after 8 secs or so then restarts again... I have the Software Install and Restore disk. It came with two. I tried that but it doesn't automatically open anything. I also tried to open in Safe mode but I don't think it get far enough along to do that... Help!!!!

I had downloaded Yosemite onto my Imac, then followed the instructions to create bootable OS on memory stick, Did that then tried to load that on my Macbook. I then made the mistake of taking it out mid install i think. Now it does what I mentioned above. The computer has tried to reboot with the memory stick in so that doesn't work... ;(

Installer reports "This disk cannot be used to start up your computer"

HT1338 After installing mountain lion, my macbook pro (2010ish) crashes every ten minutes. How can I fix this?

Title pretty much says it all. I installed Moutain Lion today and every ten minutes or so no matter what I'm doing my computer freezes up (iTunes always first) and then the entire computer freezes. What can I do to stop this?
I always have to hold down the power button to reboot, nothing else works to make it unfreeze.

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode* and log in to the account with the problem. The instructions provided by Apple are as follows:
Shut down your computer, wait 30 seconds, and then hold down the shift key while pressing the power button.
When you see the gray Apple logo, release the shift key.
If you are prompted to log in, type your password, and then hold down the shift key again as you click Log in.
*Note: If FileVault is enabled under OS X 10.7 or later, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode. Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. Test while in safe mode. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

I installed Mountain Lion on MacBook Pro and now cannot reach gmail.

My single sentence question pretty much states my problem. I downloaded Mountain Lion operating system at the store and cannot figure out how to reach gmail using Firefox like I have done in the past. If you send info on how to do this to my email account ([email protected]) I will not be able to notice it unless you have a magic wand. I am currently using Firefox all of the time when I go online. If you need a phone number: 360-753-1481.

Can I purchase Mountain Lion and make a flash drive bootable? I do not want to install it on my Macbook Pro. I have Snow Leopard on my Macbook Pro now, and due to my hard drive needing repair I need to boot off of another source, like my flash drive.

Can I purchase Mountain Lion and make a flash drive bootable? I do not want to install it on my Macbook Pro. I have Snow Leopard on my Macbook Pro now, and due to my hard drive needing repair, I need to boot off of another source, like my flash drive. I am in Paris and my Snow Leopard DVD is in Texas.

Mac OS X has a built-in disk diagnostic and repair program called fsck or file system consistency check. Here’s how to verify and repair your startup disk with fsck. As soon as you hear the startup tone, press and hold Command-S on the keyboard. Keep holding down those keys until you see a black screen with white lettering. This is called “booting into Single User Mode.” As the Mac boots in this mode, the screen reports each step of the process. The line should end in root#. Right after the root# prompt, enter the following: /sbin/fsck -fy
If repairing the disk in single user mode fails, it means one of two things. Either your hard drive itself is failing (a hardware failure), or the directory damage on your hard drive is beyond the capability of the built-in repair procedures in OS X.

After I installed Lion, my MacBook Pro can no longer detect my external hard drives or my USB flash drives. What should I do?

Apple figures that having supported PowerPC code for the last 6 years is enough so they dropped it.
Why should they have to support some that old forever? It doesn't make good business sense to support some that so few will use.
If you must play those games, my suggestion is to get an older Mac that will support PowerPC. It is going to be a difficult task to get Snow Leopard to run on a new Mac.

I'm going to install SSD in my Macbook pro, how do I install for example OSX Lion? I dont have any CD as far as I know.

Ideally, you should clone your HD as Bimmer 7 Series explains.
However, if your computer originally shipped with Lion or Mountain Lion, a clone is not necessary to merely reinstall OS X. OS X Internet Recovery will create a recovery partition, download the installer package, and install it on a completely empty SSD or HD.
Even if your computer shipped with Snow Leopard, it may be eligible to download a firmware update that creates the same ability: http://support.apple.com/kb/HT4904

The internal drive has failed.
Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.
Back up all data on the internal drive(s) before you hand over your computer to anyone. There are ways to back up a computer that isn't fully functional — ask if you need guidance.
If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to an empty drive from any of them.) Don’t erase the recovery partition, if present.
Keeping your confidential data secure during hardware repair
*An SSD doesn't need to be zeroed.
