OS X V10.7 Lion :: Can Reinstall It Without Erasing Disk
Apr 27, 2012
I did the upgrade from Snow Leopard to Lion. I've been having random issues like it seems to go to sleep (all monitors go black) and when I close the lid; the light goes on (but doesn't blink like normal sleep). Or during wake-up from sleep, after everything appears, it does the same thing. The only thing I can do it hold down the power button, wait, and restart. Today I'm on my 4 1/2 crash/reboot. (.5 because during a reboot, it locked up again.) I was thinking that maybe a re-install might fix something, but I'm not sure. When I originally did the upgrade, I had a DisplayLink driver installed which Lion moved to the Unsupported folder; don't know if this is part of my problem or not.Â

After backing up my data and then swiping my hard drive using Disk Utility, my OS seems to have been uninstalled as well. Is there a way to recover the deleted information and go back to the last working configuration? I'm on a MBP IC2D 2.16 w/ Lion.

I was restoring my MacBook pro to its factory setting by erasing the disk and reinstalling OS X lion via internet. But it is failing telling me that my network is very slow while I used the best network in my area. How should I get an OS X lion to my CP? Is it possible to get it from another MacBook pro? Or is it possible to recover the erased OS X Lion without or with external disc?

I have a 640GB external USB hard drive that I use for time machine currently. I would like to go in and add a partition to load movies to and plug it into my PS3. Can I use disk utility to create a new partition without erasing the stuff already on the disk?
And then is it possible to format a partition larger than 32GB as FAT?

I tried to install Mavericks and it told me my disk had been damaged and needed to be repaired. I took it into the Genius bar, he wiped my disk and told me when I got home to plug in my backup harddrive and click restore and it should be resolved. But I did the restore, created a new profile and everything and I can find my backup folder because my harddrive is plugged in, but don't know how to get everything from that folder back onto the computer, and back in its rightful place. i.e. pictures back in iPhoto, songs back in iTunes

Lion is just too much for me. Can I download to my previous Snow Leopard by using a SL disk to perform an archive and reinstall? Will this keep my files, folders, programs, and settings intact?

I installed Ubuntu on my iMac, and it made 2 new partitions: DISK0S3 and Linux Swap. Here's what my disk utlity looks like: When I try to remove Linux Swap, it says that the partition (map is too small. When I try to remove DISK0S3, nothing happens and it keeps running forever before I press +Q to quit.

For some reason when I'm trying to erase a CD in Disk Utilities, after clicking the "Erase" tab, every button under it is disabled. Including the "Erase" button. I tried various CD-R's, what's the deal?

I just got my new i5 iMac. I have migrated my data to the new computer. Can I erase my time capsule so as to start fresh? If I can, do I erase it with disk utility? Is this even a smart thing to do?

I've been backing up my Powerbook G4 for a few months using Time Machine to an external firewire drive with two partitions; one for the backups, and a much larger one for all my music, video, pictures, etc. I got a new mac mini over the weekend and I want to format the Time Machine partition without erasing the one with all my other files so I can start backing up the Mini.
Is this possible using Disk Utility? If so, how?
Both computers are running Leopard.

Files remain after "erasing" disk iMac 10.6.x. I'm trying to reinstall leopard and for some reason 2 folders and 2 files (totaling 90mb) were left on. I'm thinking this is just preprogrammed files for my HD but just want to make sure this is the case and not some lingering 'infected' files.

A friend suggested backing up only my necessary files on my Lion based MBP, wiping the disc clean (erasing), and then installing Maverick. He says it will clean out any old junk and make my MBP run really fast. Â

Since I activated FileVault 2 on my Mac boot drive without initializing it, I'd assume that the same thing could be done for any other drive. I've got some external drives with hundreds of GB of data which I'd like to encrypt. Disk Utility lets do it by erasing the drive and encrypting the data written afterwards.
Is there any hidden feature that allows one to convert the drive without erasing it first, like the FileVault utility did for the boot drive (even when working on it!)?

My macbook is about 5 years old. It needs resetting and, having been a student, I've moved about 5 or 6 times and have lost the disk. (Yes I've learned my lesson!) So how can I reinstall without it? I also need to upgrade my OS, probably to snow leopard, so I wondered whether I could erase everything and start from scratch whilst doing this?  If not, what options do I have? Do I need to buy the disk again? I have also got time machine backups, but they're from quite late, when the computer was already running slowly.

Somehow my permissions on my home folder are not right. Ever since SL i've had problems with these somehow. I try to change my entire home folder to: my user: read/write everyone: no access. and i apply to all enclosed items, with me as an owner, but still many folders have the permissions: system: read/write system: read/write everyone: no access how do i fix this? i can't go through all the folders manually and switch them all... how did this get screwed up? Why are there two 'system"? repair disk permissions comes up with nothing. Should i reinstall everything from scratch?

I just need to start fresh.

I accidentally removed Safari and am now trying to reinstall it from the disk. However, I can't check the box for Safari on the Optional Installs disk. I'm running 10.5.8 on an imac. I have now backed up everything (not Safari b/c I had already deleted it) to time machine and looking at doing a custom reinstall from the "install Mac OS X.app" disk.

After then parade to Yosemite I ran into hard drive issues and my 2012 iMac will no longer boot but I ca boot to Internet Recovery. My latest plan was to do an OS reinstall to an external drive then try to recover items w/ target drive. In any case, when I choose reinstall OSX, it tells me I have to verify with Apple...OK...then continue....then it says select a drive to install OSX on but gives me no selection option? Just a blank white line? Both drives (internal and external) show up and can be accessed via disk utilities.

I bought my MBP in 2012 and after more than two years of service, I am starting to feel that it is slow and bloated. As such, I would like to completely wipe the computer and start fresh. Back in my Windows days, I would simply pop the Windows CD in the computer, format the drive and install windows again. Â
But my MBP did not come with a CD or DVD, so I am not sure how to proceed. I am now running Max OS 10.9.2, but the computer came with 10.7.x (I think, not sure). Â
How would I go about doing what I want to do?Â

I have a new MP Quad and I am noticing that I am always having to repair my startup disk. I will notice the system start to slow down, I will have Onyx verify startup disk and it tells me to repair it. I will boot to SL DVD, repair the disk and it will run fine for awhile but eventually end up in the same situation. Do I need to reinstall SL or is this a hardware issue?

I want to restore and recover OSX & Logic 8 and the software i use with it (Apogee Maestro,UAD Quad & Waves plug-ins) to a new boot disk. I have both a back up of the main OS drive on a drive with Time Machine and a disk copy of the main drive (on another) as i had it before the boot disk crashed. My question is which is the best option to take when restoring the OS etc? As I have heard that there is a couple of bugs and issues when restoring via Time Machine. Is restoring via the disk copy a simple procedure? Or, should i reinstall everything completely from scratch and copy back the receipts and authorizations perhaps? Can you point me towards the best link/method to get my setup back on track? i'm using an apogee symphony pci card

I have an Imac 5,1 2.16 Ghz Intel Core 2 Duo running Mac OS X version 10.4.11 and am fairly new to Mac. I made the cardinal sin of not leaving all of the pc world behind me when I made the switch to Mac and one day after examining my software, I noticed what appeared to be an excessive amount of folders containing only 1 or 2 photos apiece, scattered throughout the system. I got the bright idea to "tidy up " a bit so I created a folder where I could easily find it, and moved the single pix there and then deleted the original folders. My mistake was soon obvious, when the slideshows I had created in Iphoto would not work and some pictures were missing.
My problem is this: I bought the computer used and it came with nothing but the main unit , the mouse, and keyboard. I found a fix to the Iphoto problem, but it requires the original system disk which I do not have. I do however have a factory Mac OS X Tiger disc from an old powermac G3 I have. I was wondering if that disc would work to reinstall Iphoto? If so, are there any special instructions to get it to work? And lastly, if it doesn't work what are my next best options?
