MacBook Pro :: How To Reformat 15"
Jun 30, 2012
My 2012 15" Macbook Pro (updated to Lion, and assume I have the most recent updated version) is running excruciatingly slow. Takes forever to start-up, and to wake up from sleep. It acts as if it is running a billion tasks at once. I updated to Lion with backing up (I know, I know, I screwed up). I then created another Admin profile, which runs MUCH better. I have run "verify disc" and "repair disc" numerous times and have not seen any improvement. I want to erase the drive and reload the system. In PC parlance, I want to reformat.Â

What is the best way to ReFormat my MacBook Pro ?
I currently have 60 GB of Apps and other stuff, and want to do a clean install of my entire harddrive....
can i just move all my apps over to an external harddrive and then put them back on after my re install ?
Will i have to re type in all the serials for photoshop and dreamweaver, etc....?

I was let down when I found that I had to reformat my MBP 13" after 6 months of use. I also had Bootcamp installed but I found that my MBP would take a long time to boot into OSX and when I did, I had a lot of spinning beach balls. Even my Bootcamp began giving me errors. After using the utilities to find out what the health issues were, I found that my repairs to the hard drive were unsuccessful and I had to reformat.Mind you I had a time machine back up, but I was frustrated that after just six months of owning the MBP I had to reformat. It brought back memories of dealing with Windows. I mean, if I have to do this again in 6 months, I mine as well use Windows since I basically did the same thing then too. (And it was cheaper!)

I lost my silly Disk DVD. I have the ones for my iMac, however they don't work. I get the message (you cannot install os x on this computer).
What I want.... this computer is about 2 years old. I want to reformat it to square one. Like brand new. I already backed everything up.
When I called apple, I mentioned I just purchased Snow Leapord.. they said.. no biggy, just install that and it will replace everything back to square one. Well, that didn't work. I still have all my old programs.

After reformatting my macbook, it seems to be running considerably slower than the "out of box" condition. For example, before reformatting restarting the system was quick. Now, when i want to restart, i have to wait 30 seconds before it restarts.
What should i do?

I bought my macbook off my friend a few months ago and then all the sudden it don't want to load. I get the apple logo then a screen that says I need to restart my mac using the power switch. I don't have any disks to reformat my mac and my friend says she don't have any either. How can I get the disks to reformat my mac?

Just bought a new iMAC 27 and I want to sell my MBP 17". I want to wipe the HD clean so the new owner doesn't get any of my stuff. Can I do it with the SL discs that came with my new iMAC because when I bought the MBP, it came with no discs. Or is there a quick way to remove all personal information? (like delete the admin account a create a new one)

As the title states, I plan on reformatting my mbp. I'm quite new to this so I really need your help. My mbp came with leopard but I later on upgraded to snow leopard. Knowing that I bought it as an upgrade, I should install the leopard cd that came with my mbp. This is where i'm getting confused, should i install all the updates before installing snow or can I immediately pop in snow and install it? And what else should I keep in mind when reformatting? Thanks in advance!

I have a 13" white macbook with leopard on it that I got about 2 years ago. Anyway, the other day I was cleaning stuff I didn't need anymore off it and I somehow accidentally moved the "library" folder that's in the "system" folder in to the trash. I tried removing it but it wouldn't let me, then my mac froze and I restarted and it just showed the Apple logo while flashing an anti-logo and a folder with a question mark on it. I took it to the Genius bar and the guy asked me if I had my files backed up and I said no, but he told me a way I could back them up on my girlfriend's mac using a fire cable and then just reformat it myself. So I bought the cable and put the files on my girflriend's mac. However, now when I'm trying to reformat it from the installer disk, it doesn't seem to be working. It shows the Apple logo and the loading gear underneath and then it switches to that anti-logo (circle with slash through it) and the loading gear continues. I let it run like this all night but still no change. I tried resetting the PRAM and other things. I've held C and held D to run a hardware test and it says there are no problems. I've held Alt/Opt and it recognizes the disk but it doesn't seem to load anything from it.

I'm still relatively new to the Mac world but I was wondering something about reformatting. I've only purchased one application and if I go to reformat in the future, would I have to buy it again?

How do you reformat a MacBook Pro (OS X 10.7.3) 2011s Hard drive? I already backed up all the files I wanted to save. But since I have the new Macbook pro 2011 (only a few months since I got it) it didn't come with an installation disc, but instead already came with all the applications. I'm wondering how to reformat the hard drive so it wipes out everything and I can start fresh and what would happen to all the applications?

Okay so I don't know what happened but before I reformatted my OS X, I deleted my 50GB Boot Camp partition, but when I reformat I notice that it says I only have "200GB" available on my HD instead of "250GB", I'm not sure what happened to the partition I "deleted"I'm still new to a Mac, is there a way to check how much space is used already and etc? I really don't know what happened to the 50GB.

I just got my new MBP finally! I'm just in the process of calibrating the battery (first initial charge). When its charged and I can turn it on, would you recommend reformatting the drive and freshly installing OSX? If so, would anyone be kind enough to be able to point me in the direction of useful instructions? (I have an idea, but dont want to mess it up).

Last month I removed my super drive from my MBP i7 and replaced it with an SSD using the New Modus caddy. This was done so I could place a 1TB Scorpio Blue in the HDD bay. Last night, I left my computer on, and I must have accidentally pulled out the power cord. When I tried to wake it, nothing happened, so I reattached the magsafe and, low and behold, OSX would not load. I restarted with the same result - the grey and black startup wheel spins continuously (not the rainbow beachball) and the OS wont load. In response I attached my external superdrive and ran disk utilities on the SSD drive, which contains the OS. Apparently, the drive is corrupt and cannot be repaired. Disk utilities displays a "B-tree" error and recommends that I reformat the drive after removing any files that I am able to.
is there anyway that I can repair my SSD without reformatting? I thought about swapping my HDD from my old MBP for the Scorpio Blue drive and selecting it as the start up drive so I could try to transfer files, but its not a S-ATA connection. Would Disk Warrior or something similar be more effective at repairing the drive than Apple Disk Utility?

I have an external hard drive upon which I put movie files that I view through a Sony box (like the Roku box). I brought my MacBook in for a repair and connected the same external HD and used Time Machine to make a back up. It did reformat it in order to do so, but since the Sony box isn't a pc or mac I didn't think it would make a difference, but now the Sony box won't recognize HD. Is there a way to reformat it on my MacBook so that I can use it on the Sony box again, or do I need to reformat it with a Windows computer? I had no issues when transferring files only and using the Sony box.
