Intel Mac :: How To Completely Reformat HD To Reinstall From Backup

Apr 6, 2012

I installed windows through bootcamp and partitioned my hard drive to about a 300Gb/600Gb windows and mac respectively. After a while i decided to remove the windows partition. As I was repartitioning the Hard Drive through disk utility my mac froze and went to a gray screen so I restarted it. Disk utility says that the process finished however it does not recognise the 300Gb I used for windows. i.e. Disk utility says there is one partition, and that the total capacity is about 1Tb.

However the spaced used and space available adds up to 600Gb, its like the mac thinks that it is repartitoned to just 1, but not allowing me to acces that 300Gb. so my question is how do i completely strip back the hard drive to basic factory settings (iv backed up all my data to an external drive) so I can reinstall the mac operating system and repair the drive to make use of its full capacity, then re install from my backed up external drive.

OS X V10.7 Lion :: Cannot Turn Off Encryption And Reformat Disk

Jun 19, 2012

OS-X Lion I now have two useless FW800 external disk drives because I cannot turn off encryption and reformat the disk. (30 years ago, in DOS, this was called a "low level format".) I think I need to use Terminal commands diskutil eraseDisk or diskutil partitionDisk but nether of those commands work. Apparently, I cannot format the command correctly or diskutil cannot remove an encrypted partition.

MacBook Pro :: Cannot Get Lion Back On After Reinstall?

Apr 14, 2012

Tried to reinstall op system on macbook pro (mid 2010) that came with snow leopard from a time machine backup and it didn't accept my password. I had upgraded to lion, guess that's part of the problem. So I reinstalled again without my time machine backup and can't figure out how to get lion back on, along with the rest of my time machine backup now that i'm back in snow leopard? Tried to use migration assistant but it said i didn't have the correct op. sys. to continue.

MacBook Pro :: Reinstall Lion Using Time Machine?

May 18, 2012

I am going to replace my hard drive (and add RAM) on my Macbook Pro (mid-2009) myself. I have Lion (10.7.4) currently, and have backed up via time machine on an external drive. I don't have Lion on a usb, and from what I read, Lion Recovery via internet isn't applicable for my macbook (pre 2010). Is the time machine backup a bootable drive? If so, then am I all good so long as my backup is completed prior to replacing the hard drive? If not, how do I create a bootable drive so I can get back to "normal"?

MacBook Pro :: Will Lion Reinstall Wipe My Documents?

Jun 28, 2012

I woke up, went to my late 2011 MacBook Pro and it took forever for the display to wake up, and it kept showing beach ball. After some minutes, the login prompt came up but with the beach ball still spinning. After waiting for like 3 minutes I decided to shut it down by pressing the power button. The computer restarted and it's giving me a screen to re-install Lion from a backup or from the app store. I shut it down to see if it will work fine, but I keep getting the same screen re-install screen. Now what I want to know is will re-installing from the app store wipe away my documents? And don't have a backup to re-install from.

MacBook Pro :: Unable To Reinstall OSX Mountain Lion

Jun 2, 2014

I recently returned from a weekend long trip.  My mom had used my Mac Book Pro (December 2012) on the guest account.  When I opened it on Monday it was unresponsive, and the screen only showed the dock.  I rebooted, but the result was a white screen with a flashing folder with a question mark.  I followed instructions on the forums, and used command r.  Now I am stuck.  I didn't back it up with time machine, so that option (Of the 4) is out of the question.  I'm using the safari one now.  I can't modify or delete my disks for the Disk Utility Option, and am unable to select a disk to reinstall Mountain Lion on.  Long story short, I seems my computer is having problems with the disk.

MacBook Pro :: Sporadically Unresponsive Even After Clean Lion Reinstall

Jun 8, 2012

My MBP 13" (summer 2009) has been getting slower and slower for a while. Finally yesterday it was just hanging on the spinning rainbow and completely unresponsive. I had to hold down the power button to restart, but even then it was frozen, no matter how many times I restarted. I had everything pretty much backed up, so I deleted my HD and did a clean reinstall of Lion.

Even that had hiccups: at first I was getting the error message that the HD couldn't be deleted because the disk couldn't be unmounted. Finally when booting from a Lion DVD I was able to delete and clean reinstall. All seemed well last night but today I am still noticing some problems. There is a few seconds delay when opening any new folder in Finder, opening a program from the Dock, or clicking on a menu item.

Sometimes the cursor gets frozen on an arrow or other special cursor, after mousing over a link or seemingly for no reason at all. When typing, I'm getting sporadic delays: three times while typing this message, the computer froze up for about 5 seconds, and then the text finally appeared. I'm also seeing similar delays in scrolling.

Sometimes scrolling works, sometimes I need to wait a few seconds for a webpage to become responsive. This is alarming to me considering that there is almost nothing installed on the computer except Lion and a few light programs (Evernote, OpenOffice). I haven't put anything back on the computer from the backup since the clean reinstall.

MacBook Air :: How To Erase Data To Make Space Available To Reinstall Mac OS X Lion

Mar 13, 2012

My MB Air is not booting (I get the ever gray Apple logo screen with the spinning wheel, and nothing happens) Following instructions I found online, I tried the disk utility repair disk and permissions and, apparently, there's nothing wrong.  Still, the system won't boot! 

I'm now trying to reinstall Mac OS X Lion, but the system requires about 0.5 GB of additional free disk space to install! 

Is there anyway I can access the OS terminal screen (command line interface), so I may delete a few files, creating additional disk space?
