Clean install Lion first?

I just want check it is best to do a clean installation or write over SL with Lion, before I install my upgrade from CS5 to CS6 standard?
Please kindly advice me. It would be nice to say why and why not?

It's not a bad idea to do a clean install before doing a major operating system update. It's not required but it makes sure you're getting reading of accumulated "crud" on your computer.
However, most important, if you choose to do a clearn install, make sure that your hard drive, and especially, all your software is backed up. It wouldn't be a bad idea also to deactivate the Adobe software.
It's not necessary to reinstall CS5 after doing such a clean install unless you want to be able to open version-specific files (e.g., Adobe InDesign). You will need your CS5 serial number if installing a CS6 upgrade.

Clean Install Lion Dsik Mount Problem - "(Illegal Seek)"

I'm trying to create a bootable USB so I can clean install Lion on my mac. However, when I try and burn the .dmg file onto my USB I get an error message along the lines of "Unable to create "installesd.dmg - (Illegal seek)".
The USB (4GB) is Mac formatted. I have tried using my Mac formatted iPod (60GB) as well but that doesn't work either.
Does anyone have any ideas?
Thanks

Hi Arun, have you migrated any data into your clean Lion installation yet? I'm curious to learn about the startup speed of such a clean installation.
While i simply updated from Snow Leopard i'm experiencing a significantly slowed-down startup. I wonder whether it's worth to start from scratch and first update to Lion and then manually install all my applications and data.
Thank you.

Clean install Lion and CS5.5 resulting in some programs in 5.1 version

I've formatted my drive and clean installed Lion (without 10.6 first) and directly Adobe Creative Suite 5.5.
But the stange thing is that some versions are not 5.5 but 5.1.
These are Bridge, Contribute, Encore, Fireworks, Illustrator, Onlocation and Photoshop!
What could be happened, but better.... how to solve this so I have my 5.5 versions.
Tnx

This is correct. No all applications were upgraded to 5.5.
There's nothing wrong at all.

Can i clean install Lion into my Macintosh HD drive and leave Bootcamp as it is?

I would like to clean install Lion into my Macintosh HD drive and leave the bootcamp drive without getting affected from it...
is it possible or do i have to do the install on all the drive?

If you have the Lion installer application in your Applications folder, then I suggest you make a copy in your Downloads folder because the installer deletes itself automatically after the installation. By saving it you can make your own USB installer:
Make Your Own Lion Installer
1. After downloading Lion you must first save the Install Mac OS X Lion application. After Lion downloads DO NOT click on the Install button. Go to your Applications folder and make a copy of the Lion installer. Move the copy into your Downloads folder. Now you can click on the Install button. You must do this because the installer deletes itself automatically when it finishes installing Lion.
2. Get a USB flash drive that is at least 8 GBs. Prep this flash drive as follows:
Open Disk Utility in your Utilities folder.
After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
Click on the Erase button. The format process can take up to several hours depending upon the drive size.
3. Locate the saved Lion installer in your Downloads folder. CTRL- or RIGHT-click on the installer and select Show Package Contents from the contextual menu. Double-click on the Contents folder to open it. Double-click on the SharedSupport folder. In this folder you will see a disc image named InstallESD.dmg.
4. Plug in your freshly prepared USB flash drive. You are going to clone the InstallESD.dmg disc image to the flash drive as follows:
Open Disk Utility.
Select the USB flash drive from the left side list.
Click on the Restore tab in the DU main window.
Check the box labeled Erase destination.
Select the USB flash drive volume from the left side list and drag it to the Destination entry field.
Drag the InstallESD.dmg disc image file into the Source entry field.
Double-check you got it right, then click on the Restore button.
When the clone is completed you have a fully bootable Lion installer that you can use without having to re-download Lion.
However, if you don't do this you can always redownload the installer by using OS X Lion- About Lion Recovery or by reinstalling Snow Leopard 10.6.8.

Clean install lion when already on Lion?

How do I clean install lion when i'm already on lion?

Your best bet would be to create a Lion Boot Disc which is actually quite easy with the OS X Lion installer and Disk Utility. The problem is that since your are already running Lion, I don't think it will allow you to re-download it to make the boot disc. One option would be to clean install Snow Leopard, download the OS X Lion installer from the Mac App Store and make the boot disc. It would be easier to use another computer that already has Snow Leopard installed and fully updated to make the boot disc. All you would have to do is sign into the App Store on the other computer and Lion should be under purchased, just don't forget to log out if the other computer is not your own. Regardless, here are the instructions on making a Lion Boot Disc:
Performing a clean install of Lion is easy once you create a Lion Boot Disc. How do I create a Lion Boot Disc, you ask? That's easy too! Just follow these instructions: http://www.macrumors.com/2011/07/18/make-an-os-x-lion-boot-disc/
The fact is that the Lion installer is packaged around a bootable disk image that can easily be burned to a standard 4.7GB DVD. With the boot disk you can run disk utility to erase your Mac, and then clean install just like you could with every other version of Mac OS X. Just don't forget to backup all your data!!!

Clean installing Lion- have some questions.

I'm gonna clean install Lion on my macbook pro and have some questions regarding the same...
should I update to 10.7.2 and then clean install or will i have to update again anyway after a clean install?
is it true that downloading mac app store apps again from the app's page reincurrs the charges?
any best/worst practices i should consider while reinstalling Lion? I'm gonna perform a clean install.
most important... how do i initiate a clean install?!
Thanks for your time, in advance.
Neerav

Thank you, that definitely suggests that it isn't actually doing anything useful!
I switched it off, cleared the PRAM and re-formatted the drive unencrypted (I found the option, it was in the dropdown for filesystem).
That appears to have been the issue, as the download and install immediately identified the disc name, which it wasn't doing before. Guess it was having an issue with my encrypted drive. I guess it's handy I'm not a secret agent or an political dissident I shall run unencrypted...

Remove Data & Clean Install Lion

Hi folks
I recently received a replacement iMac from Apple Care, when it arrived it had the wrong configuration but I did not discover this until after I had migrated all my data back. I am getting ready to return this to Apple and I am wanting to remove all my data and clean install Lion before I return it.
What is the best way to make sure all my data has been removed and re-install Lion (it came installed with Lion). Sorry if this has already been asked but just want to make sure my data has been wiped.
Thanks

Restart, holding down the CMD+R keys, select Disk Utility, and erase the HD, then select zero out data. When finished, reinstall Lion. This assumes that you've backed up your data to an external HD so you can restore it when the new machine arrives.

Best way to clean install Lion?

Right, i've posted a lot today, but i'm hoping this should be the last time:
There's two ways of clean installing Lion (that i've seen), which one is better?:
1. Putting the install.dmg onto a sd card/memory stick, holding alt whilst restarting, booting from that memory stick,

2. Starting in Lion, going into recovery mode and using that disk utility to erase hard drive and then to re-install Lion,

Thank you very much.

It really is difficult to say, the USB Flash drive is slower, but the master boot block for the recovery partition may be damaged. Your mileage may vary depending on the health of each.

What is the best order to upgrade to Lion after putting in a brand new hard drive in my MacBook Pro? Restore first? or install Lion First?

I have a 2008 macbook pro with brand new 500GB hard drive and 6GB new RAM. My old hard drive is backed up on external drive, via time machine. When the shop put in the new hard drive (there was nothing wrong with old one, it was just stuffed to the brim), they loaded snow leopard from a disk, but I haven't put anything from the old drive back on yet....I haven't even configured my mail and am just reading mail from ipad and phone these days.
Question: Should I install Lion before I restore all the old backed-up stuff, or is it important to have anything, ( like maybe preferences) already on the computer when I download Lion. I want to be selective when restoring from time machine, because my old hard drive had a lot of ancient software and junk on it that had migrated from every computer we've ever owned, and that is many, many.
So, I'm just stuck on the best way to proceed. Also, should I install the latest update for 10.6.8 before I download Lion? I see today that some new updates have become available; java, security, safari, and apple software installer.
Thanks

But I just read your next post, and it sounds like you think I should do the back-up first, or am I missing something. I think you are now recommending that:
1. First I should install Snow Leopard,
2. do the combo update of 10.6.8
3. THEN USE BACKUP to restore what I want to carry over to new drive.
4. Then upgrade to Lion.
I would restore SL and do the Combo 10.6.8 update. Then use your backup to load back in what you want. Then do the upgrade to Lion.
So what made you change your mind?
And, just to say again, the hard drive is completely new. The shop installed 10.6.8 from the installation CD, and I haven't even configured email. I'm only using safari. I just now downloaded 4 updates that software updater recommended. It now tells me it is up to date. Is there any reason to do a 10.6.8 combo updater?
Are you recommending to do the back up BEFORE I install Lion, so that there are some preferences and information about old passwords and certain information that Lion will want to know about? Will it make my life easier to back up BEFORE I install Lion?
What changed my mind was your second post. You don't want to carry over everything to the new drive and the install of Lion. You only want selective things and of course your personal files.
For that I "feel" it best to install SL, Update SL to the most current version, Then selectively restore the parts you want and then install Lion on top of that newest install of SL with the selectively restored parts on the new Hard drive.
That should give you as clean an upgrade as you can get.
Of course you could go a completely different route. Make the Lion install USB, Save all your program Install files you want to be installed in Lion along with your personal files. Then Wipe the drive and install Lion clean. Then RE-Install your programs and copy over your personal files.
That is what I would do as I do not like upgrading to a new OS over the top of an older one. I have never found that to be as clean and it always seems to carry over stuff from the older OS to the new one. But that is me.

Clean install lion problems

I am attempting to do a clean install of Lion on my old MacBook Pro (late 2009). The HD was partioned as half OS X Lion and the other half Windows 7. Here is what I have done so far:
1. Deleted the Windows 7 partiton
2. Created a bootable drive with OS X Lion on it
     - Download Lion through Mac App Store
     - Searched throught the contents to get InstallESD.dmg
     - Used disk utility to create a bootable drive
3. Plug the thumb drive into my mac
4. Restart while holding down "option"
5. I get a screen that looks like this:
6. I click on "Mac OS X" (orange one) which is my thumb drive
7. It goes to the normal mac startup gray screen with apple logo and activity monitor spinning.
Here's where it gets weird.
8. After about 3-4 minutes I get a screen that looks like this and it just hangs there:
I thought at first that maybe I messed up creating the boot drive so I wen't back and tried it again and the same thing. I read a few articles that said to try and use Lion Disk Maker to create a boot drive so I tried that as well. Same thing happens.
Any help would be much appreciated!

You are making it more difficult than it need be:
Install or Reinstall Lion/Mountain Lion from Scratch
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Erase the hard drive:
1. Select Disk Utility from the main menu and click on the Continue button.
2. After DU loads select your startup volume (usually Macintosh HD) from the
      left side list. Click on the Erase tab in the DU main window.
3. Set the format type to Mac OS Extended (Journaled.) Optionally, click on
        the Security button and set the Zero Data option to one-pass. Click on
      the Erase button and wait until the process has completed.
4. Quit DU and return to the main menu.
Reinstall Lion: Select Reinstall Lion/Mountain Lion and click on the Install button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible
            because it is three times faster than wireless.

Clean install Lion vs

Hi all
My iMac (2.4ghz intel core 2 duo / 2GB 667mhz ram / 320gb HD) is about 4 years old without ever having had any issues - it has been running slower lately and the last week have been experiencing networking problems (connecting to xbox live, streaming movies through apps on the mac to the xbox) completely out of the blue that previously didn't exist before (and i havent changed a single setting anywhere). To fix, I believe it's time to clean up and refresh the OS. I want to either:
a) clean install snow leopard or lion and re-install all apps with fresh versions, and manually add my docs (music, movies, work) across from within my time machine backup files.
or
b) clean install snow leopard or lion but run the basic restore from backup.
My questions are:
1. If i go with option b, won't i just be replacing all my currently clogged up settings/prefs/files, thus putting the problems back on there?
2. Will Lion even run smoothly with my version iMac? Would i be better off sticking with snow leopard?
Thanks!! Appreciate any advice or tips!

Thank you for the reply To clarify, the only reason i want to 'upgrade' to Lion is because it is the only boot disc I have access to right now. Asides from that I would much prefer to stick with Snow Leopard.
RAM is definitely an issue, and checking the activity monitor confirmed that. I usually run three programs most of the time on my computer, Firefox, iTunes and Vuze (to stream movies to my xbox), and they're by far the three biggest hogs of the memory! With all three of those open and perhaps mail, i've got 50mb memory free!
I will get some more RAM. But i still want to give the iMac a once over with a fresh install...
You can't have Lion Boot Disc as there is no such thing. Yes you're machine is starving for RAM that's for sure and probably one major reason it's running so slow. If you want to do a fresh install of Lion what I'd recommend you do first is to backup using either Time Machine or create a bootable clone using SuperDuper or Carbon Copy Cloner. You will need an external HD for either Time Machine or the bootable clone. After you have backed up and tested it to see that it works then you can use then upgrade the RAM, I'd recommend doing that before even thinking of upgrading to Lion. After you have upgraded the RAM then do and Erase & Install using your Snow Leopard Install Disc. After installing SL and installing all the updates to bring it to 10.6.8 then you can open the Apple Store, purchase Lion and download and install Lion.

How do you do a Clean install lion

How do you do a clean install of lion? My iMac is 8 yr old and has gotten sluggish. At one point it was suggested that I might want to do a clean install but no one ever told me how to do that since we don't have a disk!

Assuming you already have Lion installed, boot into Recovery Mode (Command-R). From there you can reinstall Lion. Note, however, that a clean install means you first erase the drive you want to do the clean install on, and unless you have a complete backup of everything that's currently on it, you'll lose it all; the clean install will leave you with a fresh operating system but nothing else. To get it all back, make that external clone, then when the clean install is finished on the internal, Setup Assitant will run and you can point it at the external clone to get all your stuff back.

Clean install Lion with Snow Leopard DVD

I want to perform a clean install of my Macbook Pro, currently running the latest version of Lion, upgraded from Snow Leopard via the App Store). When performing a clean install I have to use my Snow Leopard DVD. After this installation is completed, do I have to purchase the Lion upgrade again in the App Store?
I want to add a second hard disk (replacing the DVD with an SSD) in my Macbook Pro 17" (mid 2010). When I mount the root (/) on the SSD and /Home to my current hard disk, is it still possible to perform a restore instead of a clean install?
Any suggestions/remarks are welcome.

Not exactly. Time Machine looks for compatible Drive Partitions, it does not care what folders you have on that drive or what the current working folder is. When doing a recovery, TM will first install a virgin copy of Lion, then it will give you a list of all the backed up data it found on your backup drive so you can decide what gets installed (likely everything). Then you reboot, login and run Software Update.
You do not need that SSD. In fact, I don't reccomend it. All you need is a blank USB or Firewire drive. Jack it into your MAC and install Lion on it. Then you can boot from that drive and do whatever you want to your main disk.
Lion creates 2 partitions. One is small and holds the installer and the usual utilities. Great idea, but if your drive ever fails or has a partition problem your toast. So I always make a DVD. Use Google to find instructions on how to make it.
You don't need to install or boot 10.6 to do any of this.
There are reasons you would need to wipe your disk and start over. But these reasons are very few. Don't make a lot of work for yourself if you don't have to.
