Formatting HD and re installing OSX SL

Hello,
My MBP been busy over the past 2.5 years, the HD is full of junk from redundant apps installations.
I wish to format the HD and then install SnowL.
I do have TC backup at work and another TM backup at home.
What are the steps?

Installing a fresh version of OSX and restoring everything is rarely required on OSX, and usually doesn't accomplish anything good.
If you have redundant apps, uninstall them. Unlike Windoze, unless they have "helper" apps running, they won't cause any problems just being there, other than taking up some space.
About your only realistic alternative is to erase, reinstall OSX, then use Setup Assistant to transfer everything but apps. That will get you a fresh copy of OSX and the default Apple apps; then you'll have to reinstall iLife, iWork, etc., and all 3rd-party apps.
See Using Setup Assistant on Snow Leopard or Leopard, especially the green "Second Chance" box.

My iMac is getting really slow. It used to boot in about 30 seconds, now it's over 3 minutes. I am thinking I may backup photo's Videos and such and format the hard drives and re-install OSX. Any thoughts on this?

This computer used to boot up in about 30 seconds, now it's minutes, programs are starting to freeze, or take a long time to boot. I suspect it's bits and fragments from programs that I have used and deleted over the years, but are still floating around inside my iMac. I really don't want to re-format and re-install OSX but the lack of performance is finally starting to irritate me. (Haveing switched from windows in 2009, I can tell you, I used to reformat and re-install windows about every 3 months because I liked that fresh fast boot up feel.) Any advice is welcome. Here's a printout from a program that lists everything using my system.
Thanks.

In addition to Mike's suggestions, you only have 4GB of RAM and Mavericks does use more RAM than other versions. You may also want to look at the apps that startup on login and the possiblity of upgrading RAM.

How do I uninstall snow leopard and re-install OSX leopard?

How do I uninstall snow leopard and re-install OSX leopard?

Sorry to hear that, Snow Leopard runs as fast or faster than either Tiger and Leopard did on my Jan 2006 Early Intel iMac on 2GB of RAM?
Before you blame Snow Leopard, run the Extended Apple Hardware Test and check the SMART status of your Hard Drive to make sure that you do not have another problem.

i guess you could put the aiport utility app on your iphone, click on the aiport express there, it will show you how many devices are connected to it and the mac addresses of those devices.

Do I really need to erase and re-install OSX?

Hello all, 2 days ago when downloading an update to the OSX Operating System there was an error in the installation, bundle ended up in trash. Now I get an error message with most of my third party software like MS Word, Entorage, Firefox that there is a "conflict in the shared library". Also, it looks like when I empty trash that update bundle is still there.
I tried repair disk permissions and AppleCare tried a few things but disk could not be repaired so the suggestion was transfer all critical files and erase and re-install OS.
Is this sound advice? Any thoughts?
Much obliged in advance,
JT
PowerBook G4 Mac OS X (10.4.7) Aluminum 17"

Tiger 10.4.6 is out on DVD for $114 @ Amazon if that helps.
TechTool Pro 4.5.1 is shipping now from MicroMat which is (I think) up there with Disc Warrior now with a 'few' more features, and regularly updated.
Do you not have a FW backup drive with room on it for an emergency and backup OS on it? That would be first thing I would be doing is backing up and having an emergency boot drive. Needed to find one for family member and it is either FW800 320GB $207 from OWC or slightly smaller.
No matter what, yes, transfer the files. Maybe even boot Tiger DVD, Disk Utility, Restore, and do a volume copy.
Only once have I seen Apple offer a CD with the combo updater ($25) unfortunately it was obsolete the next day due to bugs in USB support in 10.2.4/.5 and, didn't even come with a few other "goodies" like latest QuickTime and other nice or essential software updates.
I tend to run fsck before installs or updates, to run Applejack and clear out swap files and cache folders (which does seem to help, too) and maybe Disc Warrior and/or TTP4. And only then download the combined updates to another drive or partition. Not easy when it weighs in at 140MB, but delta updates seem more like "hit or miss."
I assume you can use FireWire Target Disk Mode or something.

How do I partionera, formatera and re-instal OSX

I had a small nightmare waking up last saturday. My mac mini apple cinema screen didn't wake up. I'm running OS X 10.9.3 w. 2,4 GHz Intel Core 2 Duo/ 4GB 1067 MHz DDR3.
In safe start mode, I can acess programs. But Safari flimmers and I can't watch videos. I know that there's no sound in that mode. After starting the computer again, I can only see my desk and the menu bar. If I click on it, I get the beachball.
I have tested the computer w. apple hardwear test from the applications CD, it took about 53 mins w.o. any faults detected. I also tested the the harddrive in the toolsprogram file. Harddrive is fine.
Safari flimmers and grey sides comes up from the bottom of the page and small loggin windows just blink like a strobe.
I use Firefox to write here, but I'm an old guy and only knows Safari and would like to continue using it. Did I mention that I don't know a whole lot about computers? Copy and paste was hard to figure out after a friend wrote this cmd-c and cmd-v, but I got help from another friend in that matter.
I think something went horribaly wrong when I set it to rest on friday night, like I always do.
Do I just install the OS X Mountain Lion CD and try again?
Will my apple id account still be there?
I have done 2 backups on my music and photos, plus the harddrive.
Happy for anykind of answer, I might not understand how-to but I will figure it out.

Thanks, but I still have the same crapy Safari flimmer, I can't axcess my desktop after restart. After safe start I only use Firefox, Safari is like strobe light. My computer is from -09. I'm currently running Mavericks if that helps. I can't install OS X from my install CD, because of Mavericks.
I'de be damned if I'm going to by a third apple computer.

Selling MBPR, erased drive and cannot install OSX

Ok, so I am selling my early 2013 MBPR so have backed it up, erased the hard drive, but now cannot even reinstall OSX on it.
The MBPR came with Mountain Lion, but I have upgraded to Mavericks. I think this is what was causing the issue maybe?
I get an error message on a grey screen saying: Apple.com/support -3001F (see image)
How can I reinstall this software? I am now having to load from an old backup which is a pain in the ***, just so I can reinstall OSX.
I followed these instructions:
Re: Wipe/Factory reset of my MacBook Pro Retina that I just sold?
    Sep 20, 2013 4:49 PM    (in response to rmreid09)
Follow these instructions step by step to prepare a Mac for sale:
Step One - Back up your data:
       A. If you have any Virtual PCs shut them down. They cannot be in their "fast saved" state. They must be shut down from inside Windows.
       B. Clone to an external drive using using Carbon Copy Cloner.
          1. Open Carbon Copy Cloner.
          2. Select the Source volume from the Select a source drop down menu on the left side.
          3. Select the Destination volume from the Select a destination drop down menu on the right
              side.
          4. Click on the Clone button. If you are prompted about creating a clone of the Recovery HD be
              sure to opt for that.
               Destination means a freshly erased external backup drive. Source means the internal
               startup drive.
Step Two - Prepare the machine for the new buyer:
          1. De-authorize the computer in iTunes! De-authorize both iTunes and Audible accounts.
          2, Remove any Open Firmware passwords or Firmware passwords.
          3. Turn the brightness full up and volume nearly so.
          4. Turn off File Vault, if enabled.
          5. Use Boot Camp Assistant to remove a Windows partition, if there be one.
          6. Disable iCloud, if enabled: See.What to do with iCloud before selling your computer
Step Three - Install a fresh OS:
     B. Lion and Mountain Lion (if pre-installed on the computer at purchase*)
         Note: You will need an active Internet connection. I suggest using Ethernet if possible because
                   it is three times faster than wireless.
          1. Restart the computer while holding down the COMMAND and R keys until the Mac OS X
              Utilities window appears.
          2. Select Disk Utility from the Mac OS X Utilities window and click on the Continue button.
          3. 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.
          4. Set the format type to Mac OS Extended (Journaled.) Optionally, click on the Security button
              and set the Zero Data option to one-pass.
          5. Click on the Erase button and wait until the process has completed.
          6. Quit DU and return to the Mac OS X Utilities window.
          7. Select Reinstall Lion/Mountain Lion and click on the Install button.
          8. Upon completion shutdown the computer.
     C. See What to do before selling or giving away your Mac
*If your computer came with Lion or Mountain Lion pre-installed then you are entitled to transfer your license once. You must remove the computer from your list of registered hardware. If you purchased Lion or Mountain Lion from the App Store then you cannot transfer your license to another party. In this case you should install the original version of OS X that came with your computer. You need to repartition the hard drive as well as reformat it; this will assure that the Recovery HD partition is removed. See Step Three above. You may verify these requirements by reviewing your OS X Software License. See Terms and Conditions if you need to transfer an Extended Warranty that is still in effect (Transfer of Plan.)

Thanks LowLuster.
So after restarting while pushing Command + Option/alt + r, I get the globe on the screen for Internet Recovery.
Next step is to erase the hard drive (Macintosh HD)
Then reinstall OSX?
I'll give this a go, but I can't see the option for 'Disk Utility to Repartition the drive as One Partition to Remove the Mavericks Built In Recovery HD partition from the internal drive' - all there is is the usual disc utility to erase it?
EDIT: It's now letting me reinstall Mountain Lion after erasing the hard drive, excellent

Computer will not boot up. I have tried running disk utility and re-installing OSX. It says disk locked

I am new to Macs and have bought a 13" Macbook Pro and a IMac 21.5" 14 months ago. I have only used the Macbook pro about 15-20 times and after upgrading to Maverick it will not boot up. I get the white screen and a spinning circle. I have tried Disk utility repair and even re-installing the OSX, but it says disk locked. I do not recall setting any password protections or passwords. I now have a brick with a lit up Apple logo. If anyone knows how I can bypass the disk lock error or reset the laptop, please let me know. This has not been a pleasant conversion from PC's. Even my IMac blacks out from time to time and both happened right after my factory warranty expired.

The internal drive is malfunctioning. 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.

WinXP SP2 format time and overall install time with RAID 0.

Jan-Feb 2003, I built an Intel based system with an asus motherboard, and 2 80GB sata seagate hard drives. It took approx 11 minutes from initial "press any key to boot from cd.." to the very last step of the tour. The formatting time was, I'd say under a minute. It was phenomenal.
I just recently finished building my current AMD based computer with MSI K8N Neo2 Platinum. Among all the other stability issues I am having, it seems Winxp is slow. Is this a function of MSI's raid controller/driver?
Charlie

I remember pre-SP2 boot times were awesome on my system. Even after a clean install SP2 boot time sucks compared to SP1. Gotta live with it i guess. I'd love to get those boot speeds back when benchmarking and tweaking my system. AFAIK it is a SP2 thing and there's not much that can be done about it. If there is someone please post.

I cannot install the latest update for itunes. After installing an ssd with a dual drive kit, and freshly installing osx lion.

After downloading the update and restarting to complete the installation, as the restart process begins it is interrupted by this message: Could not install some of the updates. Then it restarts, and i am stuck with itunes 10.6.3. What could the issue be? Mac Mini mid 2011, 500gb HDD, 128gb Samsung 850 pro SSD, 8gb ram. Running OS on SSD.

First open Disk Utility and try repairing the HD
Next, I would try installing the 10.7.5 combo update

Will I lose iLife if I erase and re-install OSX ML??

Hi, I want to do a clean re-installation of OS X Mountain Lion and i wanted to know if i would lose iLife if I do so. I also wanted to know if i could selectively re-install some apps from a time-machine backup, without restoring my Mac from the time-machine backup. If not, i'd like to know if doing a selective time machine backup from the applications folder would work to restore my Mac from it. Thanks!

The installer removes the old system so their is no weight to carry.
My guess is if a reinstall helps performance then there was something in the upgrade that was not installed correcty.
I installed Mountain Lion on my Mac over the top of the previous version and suffered not ptoblems.

Cannot erase and re-install OSX 10.4.3

I have a Intel 2GHZ Imac, I bought off of craigslist, the person who sold it took it in as a trade, it only had the keyboard and mouse, it did not have the password, it has 10.4.9, so I bought the latest version of tiger OSX 10.4.3, the universal software which is for intel and power pc from the apple store, and I bring it home and put it in the computer and try to boot from the disc by holding down the "C" key and nothing happens, I tried this numerous times, I am not new to macs, I own a G5 tower and a G4 tower and powerbook, I have done this before, but on this computer it is NOT working, what could be the problem, PLEASE HELP !!!

You can also change the administrator's password from single user mode. I have not tried these instructions. These steps are more complicated..
This page tell you how to get the mac to ask for a new admin & password:
I followed JoseAranda steps and it worked. Walked me through the setup and I created a new account.
restart your computer, hold down Command-S. When you get the prompt, type in the following:
/sbin/fsck -y [Enter]
/sbin/mount -uaw [Enter]
rm /var/db/.applesetupdone [Enter]
reboot [Enter]

Here is the link from which I copied the post.
Here is another solution...
This page will tell you how to get into single user mode.

Basically, you hold down the command-s key when powering on. The command key has a little apple symbol on the lower left. It is between the alt/option key and the space bar. On a PC keyboard, it will be the windows key, I think.
You will need to change the password on some account. ( Do you know Unix. You are in a Unix single user console. ) To find out the users on the system type:
ls /Users
Pick one of the users and type passwd a-user-name and enter the new user password. You need six characters. One of these account will be the administrator.
The root account isn't enabled by default. I am not sure if changing the password on root will enable it.

How do I completely erase, re-partition, and re-install OSX 10.8?

Hi,
I have a new MacBook Pro with a 256 GB flash drive. It did not come with any OSX installation discs, probably because it also doesn't have a CD/DVD drive. Unfortunately I need to erase and re-partition the hard drive. How do I do that?
I must need to download OSX 10.8 from somewhere, put that on an external drive, .....? I have some largeish USH drives, as well as an external hard drive, and an external CD/DVD reader/burner.
Thanks!

First, press Command and R keys on boot, open Disk Utility and erase the disk. Then, close Disk Utility and reinstall Mountain Lion

OK HERE IS WHERE I AM AT HARD DRIVE WENT DOWN UPGRADED TO A 250 GIG AND NOW NEED TO KNOW HOW TO INSTALL OSX ON THE POWERBOOK G4 17

Do you have any OSX disks?
It won't boot from the new hard drive yet because there is no OS installed.
You need to use an OSX disk, put in your mac, then when turn on, hold down the C key (to boot from the CD).
Hold it down for a long time until you hear it noisily reading from the CD drive. Once OSX starts up (from CD) you should go to Disk utility and you will need to format your new hard drive.
Once formatted, you can then install OSX.
Everything is done from the OSX install disk.
If you don't have one, you can buy a retail copy from Apple (not Snow Leopard), or from Ebay. Make sure it is a retail copy, not disks that came with a Mac as they only work with the exact model of Mac it came with.

5 hours to install OSX and now running slow

I'll start from the beginning.... My 15" 2010 8gb RAM macbook pro had a tantrum a couple of months ago when it refused to load past the grey apple screen (it would intermittently flash up a 'prohibited' symbol like on a road sign). After some asking around I decided to reformat the HDD and re-install osx. It seemed to be ok, but then started freezing at points (once or twice a day). I installed smartreporter, which told me there were I/O errors and could be signs the disk was on its way out. Time for a new HDD I thought.
Yesterday I reinstalled my new HDD, began the installation of snow leopard from the disk, and waited. And waited. Went to bed. Got up half way through the night to check and it still wasn't done. 5 hours in total it took before it finally installed. Then it got to the bit where it has the fancy intro video for mac osx and it froze (music still played, just video didn't - this is with 8GB ram!). That was the second sign of trouble. Finally got to the desktop and decided to run safari, and this is where it really went wrong. I tried three times to use the google bar, and every time i typed something the spinning colored wheel came up, so no text was typed. then it wouldn't let me press return, again a colored wheel. Then I tried to close and restart the macbook, and the wheel hijacked every click of the trackpad and stroke of a key, til the point where I just closed the screen over and tried to ignore the osnet of panic.
Now throughout this process I have always assumed it was the orginal HDD that was corrupt in some way. Now the new HDD is in, things are running worse than ever. So what else could it be? Someone mentioned the logic board as a possibility, but I wouldn't know where to start with that...
any help much appreciated!

agree with sig. definitely sounds like a bad drive. I suggest you interrupt the install and 5 hours for an erase and install isn't normal. you may want to run apple hardware tests to see if something else is possibly afoot. reboot with the original leopard disk inserted and hold "d" at the chime. this will boot you into AHT. run all tests.
