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!Â
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!Â
Is there anyway I can access the OS terminal screen (command line interface), so I may delete a few files, creating additional disk space?Â
Info:
MacBook Air, Mac OS X (10.7.3), OS reinstall
I have this iMac, and now I mostly use my macbook pro. So what I want to do to this one is delete everything (of course I will back up what I need) and then reinstall Lion, so first it can be faster. And second imac run bootcamp on it so I can play some PC Games.
Today I took my MacBook to the apple store for an erase and reinstall due to about 20gb of space was missing on my HD. My latest backup was done the day before I went back to Apple to reinstall Lion. After I restored my data from the backup, the address book app and the app store app are both missing. My address book data is on iCloud so I'm not that concerned about the data but I would like to get the app back on my MacBook.Â
I want to reinstall Mac OS X Lion with saving my programms, docs and photos. What should I do then? I know that Time Machine backups data with the system. But Ineed to backup my files and then on clear system I want to restore this backup. Please reply with the steps which should I do. And where should I download original Mac OS X Lion image?Â
PS I bought MacBook Pro with pre-installed Lion. Â

I bought an imac 2 years ago, and updated it to leopard when that was released. I no longer have the discs i used for Leopard, only the original mac os x 10.4 discs.I am very soon going to be selling this machine and need to wipe everything so that all is left if the operating system in the form you would expect as if you had just bought a new mac.How can this be achieved, i tried disck utility> erase, but only erase free space was 'highlighted'.
I was having problems with the external drive where I store my Time Machine backups, so I tried plugging and unplugging the drive but could not mount the drive. I ran Disk Utility and tried to verify the disk, which told me the disk needed to be repaired. I tried to repair the disk only to get an error message that Disk Utility could not repair the disk and it needed to be reformatted. So I tried to erase the disk with Disk Utility only to get the error message "Volume erase failed: Media kit reports not enough space on this device for requested operation". I am not sure what else to try at this point and could not find any similar questions here. Â
The drive in question is a 3TB USB Seagate Backup + Desk Media, formatted as Mac OS Extended (Journaled). It's divided into two partitions, one of which (2.2 TB) holds only Time Machine backups of my desktop and laptop and the other of which (800GB) is formatted similarly with some files stored on it. I was able to verify and repair this other partition. I'm running Disk Utility 13 on an iMac (2.8 GHz Intel Core 2 Duo) running OSX 10.8.5Â ...
I want a brand new OSX installatetion. What is the best way to completely erase my SSD (to make it brand new) and reinstall MAC OSX (i can use internet WPA secure Wi-Fi to reinstall MACOSX Lion). On macbook air late 2011.
I have a Macbook Pro with OS X Lion. I want to reinstall Lion without losing my data. I dont have a TimeMachine or backup hard disk. Can the Command+R option with Reinstall thing will wipe my data ? Is there a way so i can have a fresh OS X Lion and and preserve my files ?
I managed to interrupt the computer when I selected the "Erase Free Space" option. I had 0GB left on the computer and had to cancel almost all of the applications. I Googled and found that /var/root/Library/Caches/TemporaryItems should locate the file when entered in Terminal, but whenever I try that, it just says "Permission denied." It only asked for a password once, and when I tried entering it, it said that there was no such file. I located a few other temporary files and deleted those, and also tried making empty folders on the desktop to empty the trash. It freed up 6.7 GB, but there's still a lot of space missing. I'm not sure what else to try or how to get the space back.
The Macbook of a friend of mine doe not boot anymore after an abordet Itunes-Upadte yesterday evenig.How ever, the Save-Boot-Log tells me, that "The System bootstrapper has crashed: Trace/BPT trap: 5" I assume that i have to reinstall OS X to get the Macbook run again. This is where i'm sure, whether the Install via Recovery-Partition -> Reinstall Lion does a complete Clean-Install (all Data that's been on the HDD will be gone) or does "only" some Repair-Install-Stuff which preserve the personal Data and Software on the HDD. Nevertheless i'm going to Backup (CCC) the broken installation to be on the safe side anyway.

Every time I try to erase music from my USB Key or Phone.
You can see that the music or files have been erased, but it doesnt free up and space. When you pop the USB Key into the stereo or play music on the phone, all the files are there.
I have to go through the Disk Utility option to erase stuff, but this erases everything. When you erase on the PC, everything is fine.
Prior to Lion, whenever I open a window at bottom it would show # of items and space available in that window. Now all that info is missing in Lion. How can I get it back? Looking at options under Finder, I don't spot a way to restore like "15 items, 7GB available" as I used to see.

Out of the blue tonight, my Mac Mini running OS X Lion will no longer secure erase my empty space. Whenever I try to do so, I get the following error:Â "Secure Erase Free Space failed with the error:Â Some information was unavailable during an internal lookup"Â I've rebooted to no avail. I also did a complete shut down and boot up, but the error persists.
I just received my new MacBook Pro. It came with 250 gb of hd space. I had to do an erase and install on it because of an issue that came up while using the migrant assistant. So, after doing the erase/install it says that I only have 216 gb of space left? And thats without the applications CD that I have to put in which will be about 4 gb. I believe when I first turned the computer on before doing the erase/install it had about 235?
I'm having a pretty serious problem. I attempted to erase the free space on my HD, as I do from time to time, except this time it appeared to hang/freeze at the end, when it gets to the part where it creates a temporary file. I waited for several minutes and it didn't move. I tried clicking the skip button, but that did nothing either, so I force quit Disk Utility.
The problem is, it left the disk at "Zero KB" of free space, effectively making my computer inoperable. I was in the process of studying for a huge exam tomorrow, and am currently flipping out.
If it matters, I'm on a Macbook Pro 2.33 GHz Core 2 Duo, running 10.4.
I really don't want to have to reinstall the OS and import the old files, but my real fear is that I will have to do a fresh install of the OS.

I have a 2007 Blackbook with Snow Leopard installed. I tried to install Bootcamp but it said that I had to do an erase + reinstall first. I booted my mac up from the OS X disc, got past the language menu, then got a pop up stating "MAC OS X Cannot Be Installed." I can't click on Disk Utility or anything else on the menu bar. How else can I erase my HD?

I cannot understand why I am unable to reinstall my Mac OS X installation disk 1 after performing a 7 pass erase. I kept the installation disk in the computer because iMac would not allow me to eject it. Plus I needed the installation disk in my computer to perform the erase in Disk Utility. did I erase the entire installation disk?
I was given this macbook by my boyfriend and wanted to erase all his data and stuff. I have the mac boxed set for snow leopard for this macbook but I am not sure where to begin, how to start from scratch.
Does anyone have how to claim more space on the MBA without having to do a full reinstall? Also anyone using bootcamp + vista recommend a partition size?
