Hi, how I format the drive and install a fresh copy of Lion?

Hi, I have a Lion installed on a Mackbook Pro 2011, I had Leopard, then Snow Leopard and then Lion, but with so many instalations without formating the system is not working well, I am using an iMac at work with a clean install and is much more stable.
How can I format the hard drive and install a fresh copy of Lion???

Install or Reinstall Lion from Scratch
If possible backup your files to an external drive or second internal 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:
Select Disk Utility from the main menu and click on the Continue button.
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 Erase tab in the DU main window.
Set the format type to Mac OS Extended (Journaled.) Click on the Erase button and wait until the process has completed.
Quit DU and return to the main menu.
Reinstall Lion: Select Reinstall Lion and click on the Install button.
Note: You can also re-download the Lion installer by opening the App Store application. Hold down the OPTION key and click on the Purchases icon in the toolbar. You should now see an active Install button to the right of your Lion purchase entry. There are situations in which this will not work. For example, if you are already booted into the Lion you originally purchased with your Apple ID or if an instance of the Lion installer is located anywhere on your computer.

How to format and install a fresh copy of Mac OS 10.6.4, with another MacBook CD, because i lost the one that came with mine, thanks.

Dear user, can i format and install a fresh copy of Mac OS 10.6.4, with another MacBook CD, because i lost the one that came with mine, thanks.

As you need to be on 10.6 to be able access the App Store to download Lion, either get replacement discs via Applecare (you'll need the MBP's serial number to get the right ones) or get the SL retail disc. I would recommend the Original disc replacement set (assuming they were 10.6) as they carry not onlyApple Hardware Test for your model, but the iLife apps other bundled sftware that isn't on the retail disc.
Once you've installed, and used Software Update to get to 10.6.8, you can then get Lion if you're feeling masochistic.

I have purchased a mac mini only to find I am unable to run Logic pro 9 , is there any way this can be achieved? It has been suggested that I partition the drive and install a copy of an older operating system to run the Logic Pro, is this feasible?

Only with a whole lot of effort and instability. As the new Minis have
hardware (HD4000, USB 3.0, etc.) that is totally unsupported in old OSes.
The only option would be to see if it would work by installing in a virtual machine
running 10.6.8. I'm sure there will be some performance hit but whether it would
be enough to be unusable is the question.

Welcome to Apple Support Communities
Open a Finder window, and your external drive should show up in the sidebar, under "Devices".
A different way is to go to Finder menu (in the menu bar) > Preferences > General, and tick "External disks". If your external drive is detected by OS X, it will show up at the top right corner of Desktop, so double-click it to access to the content.

How to format new HD and do a fresh install on used computer

i just bought a new-to-me used mac pro with a new hard drive and i want to install yosemite on this drive. i haven't done this before so i am at a bit of a loss.
the hard drive is not formatted since it is a new hard drive and there is no data on it. i do have access to my old mac pro which does have internet access.
how do i format this hard drive if it is in a new computer with no OS on it?
also is this the correct URL for installing yosemite on this computer?
thanks in advance

i mean, is this as simple as downloading the yosemite installer to the desktop of this machine, connecting the two machines via firewire cables and double-clicking on this installer dmg?
Pretty much. However, with an unformatted drive, I'm not certain what will happen if you try to start up the new-to-you Mac Pro in Target Disk Mode.
To boot it into Target Disk Mode, hold down the T key during restart. If you have a monitor connected, you'll see a bouncing FireWire symbol on the screen.
Connect the two Macs with FireWire and the TDM Mac will show up as a Hard Drive on the other, normally-booted Mac. Run the installer and choose the drive that is on the TDM Mac. If it doesn't show up, try opening Disk Utility and see if you can see the drive--I kind of doubt this will work. If you do see it, you can Partition it as Mac OS Extended (Journaled) with a GUID Partition Table (Options button on the Partition Tab).
FireWire Target Disk Mode is what you'd search for.
If TDM doesn't support an unformatted drive, you will have to use Internet Recovery to format the drive, or do as previously suggested and put the drive in your other Mac Pro and format/install there.

My iMovie 9 will not install after formatting hard drive and installing Mavericks what are my options?

I have not used my iMovie ever since I formatted my Hard Drive and installed Mavericks. I went to put the disk in from when ilife was originally shipped with the computer and it just spits the disk right back out of the superdrive. Is there anything I can do to not have it just spit a disk out without asking for user input. Any help would be greatly appreciated, I don't want to buy the new version.

Here are the original specs of your computer. The specs state that the original hard drive was 320GB. You have since replaced the factory drive with a 1TB (1000GB) hard drive. The HP recovery routine seems to have issues with hard drives that deviate from the original size. The partition issues you are experiencing may be a result of this. As for the rest of your issues, it sounds like the SP3 install went bad.
If I were you, I would consider reinstalling the OS using your recovery discs by doing a complete "destructive" reinstall/recovery. Afterward, I would post the size of both the c: and d: partitions... and go from there.

I recent la format the drive and create a case sensitive jornal and put a password. How I undo it if I just see the whole drive as the recovery disk

I want to format my computer and I start to do that but I fondo a copy of the boot folder on the drive, not the recovery drive. I formated and make it case sensitive jornal with a password. Then I put a password in main too. So the drive the entre drive become my recovery drive.So I have two recovery drive I think.I learn almost all the diskutil comando and I don know how to fin it. The disks are not showing the one with the passwords.

Hi Kappy,
Just wondering if you had any advice for my situation . . .
My time machine backup was backing up to a drive that was "Mac OS X Enteded Journaled, Case Sensitive." I had no idea what this meant, or that it would even cause issues.
I took my computer to the Apple store yesterday, and they wiped it clean. When they tried to restore it from the Time Machine backup drive, it would not work. Their guess is that Time Machine cannot restore from a drive that is "case sensitive."
Any thoughts on how I can convert my time machine backup data from a "case sensitive" state, to a "non-case sensitive" state? I've tried to just drag and drop the files from the case sensitive formatted drive to a new drive that I have that is formatted non case sensitive, but I get the following error message:
"The volume has the wrong case sensitivity for a backup"
I just really want my data back - I thought TimeMachine was the way to go (and was supposed to work) but unfortunately it is not.
Any help you can provide would be greatly appreciated.
Thanks,

How to format external HD and install software on it? Help, please?

When install programs on my Mac there is only one option for installation - on the internal HD, the other drive plugged in the computer appear with exclamation mark - ie they are not available for installing anything on them.
I want to be able to install some small programs , or a web browsers on external drive , just to see how they works, etc.
How to format an external HD or USB flash drive (if its size is enough)
so it is possible for install a program on it instead on the internal hard drive?
Thanks to all!

That's the theory. Note that you'll wipe the external drive in the process, so if there's anything you want on it, get it copied elsewhere first. It’s always wise to back up any important stuff on your MacBook of course before doing anything like this (but not to the drive you’re about to use!)
With the drive connected, open Disk Utility, highlight the external drive in the sidebar (that's the drive itself, usually listed by the manufacturer's name and the size of the drive). Select 'partition' in the tab bar, ensure the drop-down on the right is set to 'Mac OS Extended (journaled)', give the partition a name in the box above that (like 'ext HD' or whatever). Click on the 'options' button below the diagram and select 'GUID Partition Table' (very important - it won't boot SL with any other setting). then click the 'apply' button.
Once that's done, close DU and insert the 10.6 install DVD in the MacBook (or whatever the Mac is). After the licence agreement there’ll be a picture of Macintosh HD, but underneath should be a button saying ‘show all disks’. click that and select the external drive, then click install and follow the instructions.
Note that if you do this with the grey install disk that came with the computer, you will only be able to boot that computer with it, as it’s model specific. If the install DVD is a black retail one, it should theoreticaly boot any Mac (but note the licence conditions).
Once the install is complete, boot from the external HD by either selecting it under ‘startup disk’ in Sys Prefs, or by holding down the alt key during restart and selecting the drive from that screen. You can then install any progs you want and try them out from there. (don’t forget to reset the startup disk when you want to reboot from the MacBook).
If you don’t have a DVD, or you want a duplicate of your existing system, go with the clone idea, using CCC (not because it’s better than SuperDuper, but because it’s free if you don’t mind putting up with a few ads while it’s working!)
Hope that does the trick for you.

How To Wipe Hard Drive and Install Mavricks.

Hello,
So I want to erase my hard drive completely and install mavricks back on to it. From reading other articals some said that if your computer originaly came with Mountain Lion (mine did) that you DON'T need a install disk. So now im lost in the confusion. What I want to know is how to completely Erase The HD and istall Mountain Lion Again. The way Apple told me to do it was after I click erase on the HD (throught DU) a window would pop up and ask if I want to reinstall Mountain Lion. Is that true?
(One more questing aside from the topic is, can you install a OS from Flash Drive.)
Thanks

How to format my mac and install fresh copy of Snow Leopard

Hi guys,
When i bought my mac, it was coming with Mac OSX 10.5.6 Leopard.
I want to remove everything and start my mac from beginning again using Mac OSX 10.5.6 Snow Leopard directly. is it possible?
I already bought the Snow Leopard DVD.
Can i just directly re-install and format my mac using this Mac OSX 10.6 Snow Leopard DVD?
Or i need to format it first using old Mac OSX 10.5.6 DVD,then after that upgrade to Mac OSX 10.6?
Please help me guys..
Thanks a lot..

Definitely yes.
I know that you know that there are two kind of installs for Leo: upgrade and erase and install. In principle, there would be little difference between the two. Many here say that upgrading, versus erasing and installing, is the superior procedure provided that one's prior installation is in very good condition. Others feel differently. I say just do what you prefer. My bet is that percentage-wise those getting good installs from an erase and install, particularly if all apps are reinstalled, rather than migrated, is higher than for upgrade--but probably not appreciably higher.
The processes leading to the final outcome should lead to a good outcome in either case. But, things can go wrong either way. I am not going to try to elaborate much on the specific ways that things could go wrong either way. But, for the most part, they would have to do with the way migration works and the migration technique used (if used), in the case of erase and install, and the existence of problems in the system existing prior to installation in the case of an upgrade.
To erase and install,
1. Start up from your Sno DVD, and start the installer.
2. Choose your language
3. Use the menus at the top of the next screen to start Disk Utility.
6. Erase your drive Mac extended (journaled).
7. Quit Disk Utility and continue your installation.
To do an upgrade install,
1. Start the installer from your Sno DVD either from your desktop or by starting up to the DVD.
2. Choose your language.
3. Continue your install.
Whichever kind of install you choose, you should be well backed up.

How to format my G5 and install FCP?? Plz help URGENT

Hi Everyone,
Since I installed FCP suite my compressor never worked, So I decided to format my mac and reinstall Tiger and FCP.
Can some one give me a quick steps on how to format my mac. Never done it before..
Thanx so Much

I know how it sounds but blieve me I tried everything. I gathered the process of reinstalling Tiger is not as bad. Just insert the DVD and follow instruction.< </div>
Umm, well, the Scorched Earth Method is drastic and cannot be undone. But,m yeah, it's easy.
By the way is there a prefrence on how to install FCP or just put cd's and follow wizard. eg. Is there a sqequence on what to install first.< </div>
Put them in and follow the instrucitons.
Thnx alot for ur reply David.< </div>
No problem, we just hope you don't get BAD advice here.
I hope compressor works after this < </div>
There is no reason at all to believe it will work after reinitializing your system. None at all. There's hop, but no rationality.

Would I be able to install a fresh copy of Lion on my macbook? I just replaced the harddrive and don't want to restore my old os.

I just replaced the hard drive on my macbook. The OS on my old hard drive is OSB Tiger and would like to install OS Lion on my new drive without having to restore the old OS and then upgrade to Snow Leopard in order to upgrade to Lion. Any suggestions would greatly be appreciated.

Without Snow Leopard you cannot purchase or download Lion, so you haven't much choice unless you wait until Apple releases their USB flash drive with Lion later this month - $69.00.

Formatting a new hard drive and installing os in it. Help!

hi mi name is john.
i recently bought an i book (its an ibook, it only says that on the front screen) on ebay came with a crack screen which i replaced when i started it a folder with a flashing question mark appeared. i researched and found out i it was a hard drive problem. i thought. i replaced it with a 120 GB hard drive. when i started it again the same happened. i also have a macbook pro woking fine i try to use the remote install it didn't worked over the airport i haven't try the fire wire to usb. i also bought original install and restore cd with 10.4.9 os for it. but it doesn't boot from it,
i looked on the support forum i tryed everything in this forum http://support.apple.com/kb/TS2570 even Reset the NVRAM / PRAM, except for the erase and install because i cant use the start up disk as i told you it doesn't boot from cd. i press the c key and nothing happens it just keeps flashing. by the way the ram is 250 mb i don't know if thats a problem because the drive is 120 GB, it also doesn't strat up with the cd of my mac book pro 10.6.6
it just doesn't start up from the cd. i know i have to prepare the drive to formatted as HFS+ (Extended), but how i do that now. if i have everything put together.

Welcome to Apple Discussions.
Lots of issues here.
when i started it a folder with a flashing question mark appeared. i researched and found out i it was a hard drive problem.
Not so much a hard drive problem as a case of no valid operating system found. The underlying reason could be a hard drive issue but maybe somebody just wiped it and didn't put one on.
i replaced it with a 120 GB hard drive. when i started it again the same happened.
Still no operating system until you format the drive and put an OS on.
i also have a macbook pro woking fine i try to use the remote install it didn't worked over the airport i haven't try the fire wire to usb.
A system from an Intel MBP, especially 10.6, will not run a G3 PPC computer.
i also bought original install and restore cd with 10.4.9 os for it. but it doesn't boot from it,
If this is a grey disc that is only intended to work on the computer model with which it was supplied. You need retail version discs which are black in color and harder to find (and more pricey).
i looked on the support forum i tryed everything in this forum http://support.apple.com/kb/TS2570 even Reset the NVRAM / PRAM, except for the erase and install because i cant use the start up disk as i told you it doesn't boot from cd. i press the c key and nothing happens it just keeps flashing.
Because it's the wrong kind of disc.
by the way the ram is 250 mb
Tiger minimum RAM requirement is 256MB, but that really is a minimum.
i know i have to prepare the drive to formatted as HFS+ (Extended), but how i do that now.
You need to find a retail version (black) set of discs. Tiger would be better, but you need more RAM. Panther would be okay but there's definitely limitations in terms of available software.
Operating systems you'll have to find on the used market. Expect to pay nearly $100 for Tiger, probably less for Panther.

How to format the whole hard drive?thanks in advance.

I tried to install the whole system again, how to erase the old data and programs and install the new os?

Prepare Your Mac for Sale
Boot from the OS X Installer Disc One that came with the computer. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select the startup volume from the left side list then click on the Erase tab. Set the format type to Mac OS Extended (Journaled) then click on the Options button. Select the one pass Zero Data option and click on the OK button. Then click on the Erase button.
Note: You can skip the Zero Data option if you are not concerned about removing sensitive personal data from the hard drive. If you choose to skip this part of the process then it is possible for others to recover data from the hard drive. The Zero Data procedure will prevent others from getting access to your personal information.
This process will take 30 minutes to several hours depending upon the size of the hard drive. After formatting has completed quit DU and return to the installer. Now complete the OS X installation. At the completion of the installation do not restart the computer. Instead just shut it off. The next user will be presented with the Setup Assistant when they turn on the computer just as it would if new out of the box.
In the future you need to provide your OS version information and hardware configuration in your forum profile. Sort of difficult to tell you how to erase your drive and install OS X when we don't know which version of OS X you will install.
