My MacBook Pro won't allow me to install Mavericks because "The disk cannot be used to startup your computer"

I had this same problem when I tried to install Mountian Lion. I already tried changing my partitions and it wont let me because of something about my filesystem verification failed. I have no idea what to do. Help!

AishaniKumar,
which model MacBook Pro do you have? If you click on the Apple menu, hold down the Option key, and then click on “System Information…”, a new window will appear. Which Model Identifier is shown in the Hardware Overview of that window?

Step by Step to fix your Mac

If you are downloading .exe files, those are Windows programs, and will not run on your Mac unless you install Windows on it. (That is possible, if you need one of those apps.)

Reinstall OS X:
Reinstall Snow Leopard without erasing the drive
Do the following:
1. Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Reinstall Snow Leopard
If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
Download and install the Combo Updater for the version you prefer from support.apple.com/downloads/.

(SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button.

Reinstall Lion: Select Reinstall Lion and click on the Continue button.
Note: You can also re-download the Lion installer by opening the App Store application. Hold down the OPTION key and click on the Purchases icon in the toolbar. You should now see an active Install button to the right of your Lion purchase entry. There are situations in which this will not work. For example, if you are already booted into the Lion you originally purchased with your Apple ID or if an instance of the Lion installer is located anywhere on your computer.

Dvd/cd drive works but won't allow me to install new programs from disk, doesn't recognize the disk,

dvd/cd drive works but won't allow me to install new programs from disk, doesn't recognize the disk, what can I do?

Well I was able to obtain a work around download of Flash and it installed fine but Firefox tells me it needs updating so I go out, thinking I'm "IN" finally to update it and I get that issue of not being able to get the update for it. It's a regular laptop, not a touch screen or one of those new fangled ones for todays world. In fact it's a refurb so it's probably origin date was a year or so ago before all this MS stuff took off fully. So not understanding why I'm feeling like I'm being BLOCKED from getting the updated Flash I need and desire. If I click on the little "X" and tell it to ignore the warning the vid will play just fine but don't want to have to do that every time. Must be a better way.
Again, I'm sorry for posting in the wrong forum, getting this posted in the Flash forum was my desire but the way Adobe has this set up I just couldn't figure it out. I belong to ALLOT of forums and most are pretty straight forward but this one is confusing!

My macbook pro won't go to sleep when I close the lid

I've been having this problem for a couple of years now, and it's getting pretty annoying.
I got this MacBook Pro in April of 2011. Otherwise, it works great. It goes to sleep when I go up to the apple menu and select "sleep." BUT, when I close the lid, it stays on. Heaven forbid I don't have it plugged in, because then the battery will be shot! It also won't go to sleep automatically when I leave it for a long time. Yet another potential battery drain.
How do I fix it so that it goes to sleep automatically when I close the lid and when I leave it alone for a while?
In Energy Saver, I have checked all the boxes necessary: "Put the hard disk(s) to sleep when possible" "Wake for network access" and "Automatically reduce brightness before display goes to sleep."
Am I missing something here, or does my computer just have a defect?

I had the same issue.
I used an external monitor but all of a sudden when I closed the lid my Macbook Pro did not go to sleep!
I solved the problem with a SMC reset.
Try to do it...

I have just purchased my first MacBook Pro and it is pretty fantastic. I own the disks for Microsoft Windows 7 ultimate, and Office 2010 Professional Plus, and need to run them in this Mac. 32 bit discs. Can this happen in boot camp?

I am trying to run Windows and Mac OS on my brand new MacBook Pro. I need to be able to boot to either one. I don't need a lot of hard drive space for the Windows OS. However, the software discs I own for Windows are 32 bit install. Is there a way to run this with what I have? I have the new MacBook 13 in. with retina display. 2.6Ghz i5 with 8GB RAM and 512 GB PCIe Hard drive.

Hi guys! I have a new Macbook Pro purchased from Best Buy yesterday. I had the Geek Squad upgrade the RAM to 8 gigs (They only had PNY brand, I was concerned but went with it anyway). I had them install Boot Camp Windows 7 Ultimate. Today I picked it up and when I started playing with it I learned that they installed the 32 bit version of Win 7 Ultimate instead of the 64 bit version, why, I have NO IDEA.
So, I want to replace the Win 7 installation with the 64 bit version but have read that this can be tricky. What is the proper way to do this? I'm not sure I trust the Geek Squad to do this for me.
I assume I need to reformat the Windows partition, defragment and then install the 64 bit version of Win 7 Ultimate, but am not completely sure. I want to be sure that I do NOT do anything that could affect the Mac side
What do you guys think?
I think you should take it back to the Geeks and tell them what you want, I also think you should backup before you do.
You do not need to reformat or repartition, you need to reinstall Windows from a 64bit copy, 32 & 64 have identical requirements as far as partition and format go, defragmenting has nothing at all to do with your needs.

My Macbook Pro won't allow me to update from Quicktime 10.2 to 10.7

I need QuickTime 7 on my mac to play some files for work, and already have QuickTime 10.2 on it, which my Mac won't allow me to uninstall. And when I try and install 7.7, I get an alert telling me that 'This version of QuickTime 7 can't be instralled on this disk because QuickTime X is already present. Please use Software Update to install the appropriate version of QuickTime for you Mac.'
Yet when I use Software Update, there is nothing to update.
Any ideas?

My MacBook pro won't allow me to double click to open files or select the music I want to play, how do I fix this?

When going to open a file or select a song to play in iTunes or opening links I used to be able to double click on my track pad to open files or links, now I have to tap once with two fingers to open the "right click" option on a normal mouse pad to be able to select it. How do I fix this in order to be able to just double click the track pad to open the folder or link?

Hi kylec4544,
I'm sorry to hear you are having this issue with your MacBook Pro. If you are having issues opening things by double clicking on them, you may want to double check to make sure the double click speed hasn't accidentally been set too high, as noted in the following article:

My MacBook Pro won't charge when I plug it in. the green or orange light won't even turn on. The computer is dead already, so I cannot mess with my settings. What do you suggest?

I have a Mac Book Pro with the serial number: C0*******TY3 and the model no: A1278. I wanted to charge it this morning, and it won't charge meaning that the light even won't turn on, and also my computer is dead, so I cannot change anything on the system preferences. What should I do? I will make an appointment at the Genius Bar, but what do you thing the problem is here?
<Edited By Host>

First see the MagSafe troubleshooting tips:Apple Portables: Troubleshooting MagSafe adapters and check to see that all looks ok. You might want to try using another charger in case the charger is faulty. If that doesn't help, take the MacBook Pro and charger to an Apple store genius bar and have the technicians test the system to see where the fault is.

My Macbook Pro won't shut down after installing Lion. Anyone have a suggestion to fix this?

Just installed Lion, and it won't shutdown!
The only way it'll shut down is if it drains the battery.
Help!
J

Lots of other people are complaining about their Macs taking long times to shutdown. Some solved it by reinstalling Lion from scratch (without using a Time Machine backup and simply copying all their files on to the new install).
Others discovered old software that is no longer compatible with Lion (I found Mac The Ripper in mine, plus many others on day 1). I uninstalled some apps using App Cleaner (google it, it's free and it's awesome).
I was having a hard time shutting down my macbook pro, now it's back to normal.
Try finding applications that are not compatible with Lion. Their icons should be greyed out and with a diagonal line crossing it. Make sure you erase these applications and library related files, which is very simple if you use App Cleaner. And make sure you look into sub-folders inside the Applications folder, as I missed a couple because they were not immediately visible.
Hope it helps. If it does, let us know.

'09 MacBook Pro won't start up after installing new hard drive and restoring from an external hard drive.

I am in the process of replacing my hard drive and have run into a problem. I reinstalled OSX 10.6.3 using a DVD I bought off Amazon. That went well and I then restored my hard drive using an external and Time Machine.
After that, things still looked good but I couldn't log in to my user (and access my MacBook) because my password wasn't working even though my hint was correct. Yes, I am POSITIVE my password was correct; I even tried a couple other passwords to humor myself. I then gave up and decided to restart the computer.
Now my MacBook won't start up at all. It goes o a gray screen with a still loading symbol for a couple minutes and then goes to a solid light blue screen. I've tried starting up while holding command+R and I tied holding just command and neither worked.
Did I install the wrong OSX because I didn't use the same DVD that came with the laptop? Is there something wrong with my hard drive already?
Please help =[

You probably bought the wrong RAM that has different pin assignments, so it won't fit in the slot. Return it.
I bought 4GB Memory online for my MacBook, so I could get it to run twice as fast.
Doubling the memory does not make your computer run twice as fast.
