There hasn't been any physical installation DVDs available for Mac operating systems since Snow Leopard (10.6), with Lion (10.7) and Mountain Lion (10.8) both available via the Mac App Store as downloads only. So, if you wanted a backup install disc in case something went wrong, or in case you wanted to install Mac OS X on your computer without signing into the Mac App Store, you'd have to create a bootable DVD or USB drive yourself using the InstallESD.dmg, which. Unfortunately, that Disk Utility method does not work for the newest Mac OS X 10.9 (Mavericks) that was released as a free download on Tuesday. Technically, you can still use Disk Utility to make a bootable USB drive, but the process is more complicated than it's worth. There are a couple alternatives, though, and they're both fairly easy. Method #1: Using Terminal Since we don't want to use Disk Utility anymore to make a bootable Mac OS X Mavericks install drive, we'll have to resort to the Terminal application on your Mac. Step 1: Download Mavericks from the Mac App Store Before we get to the USB drive part, make sure you.
Either the OS is corrupt and you cannot fix it even in safe mode, or you are trying to conserve hard drive space so you can keep your big multimedia presentation. 2 - Boot the USB drive and install. If you need, type boot options, for example: -v (verbose boot) [default] -x (safe) -s (single user) GraphicsEnabler=yes (enable graphics card How to format USB or external drive in Ubuntu. Taking Screenshots in Mac OS X. Submitting Your App to AppStore.
Step 2: Format Your USB Flash Drive with Disk Utility Since the Mavericks install file is over 5 GB, you'll need an empty USB flash drive that's at least 8 GB in size, formatted as Mac OS Extended (Journaled). To make sure it's good to go, we'll just reformat it. Plug in your USB drive and open up Disk Utility. Though we don't want to use Disk Utility to make the bootable drive, we still need it to make sure the USB drive is formatted correctly. Select your flash drive from the left side in Disk Utility, then select the Erase tab.
Make sure the format is Mac OS Extended (Journaled), keep the name as Untitled, and hit the Erase button. If for some reason it looks like it's stuck on Copying installer files to disk., you might want to try again. I had to do this, and it worked fine the second time. If that doesn't work, try another USB drive.
Alternatively, you can use the next method. Method #2: Using DiskMaker X If you're not comfortable using Terminal on your Mac, is for you. This app has actually been around since Lion and Mountain Lion, and was previously called Lion DiskMaker, but it's recently been updated to work with Mavericks. It's free to download and use, but you can donate to the devs if you want. Step 1: Download & Install DiskMaker X Just download and install it to your Applications folder. Also, make sure you already have the Install OS X Mavericks file there, too, and a properly formatted USB drive before continuing.
Step 2: Run Through the Easy Instructions Now open up DiskMaker X and choose Mavericks (10.9). It will find the installer file in your Applications folder.
Select Use this copy, choose the USB thumb drive option (if that's what you're using), select the partition you want to erase (e.g. Untitled), and hit Erase then create the disk.
Modern versions of Mac OS X no longer need you to. However, that’s not the only issue that can occur with a disk or file system.
Mac OS X contains a variety of tools for repairing disk, partition, and file system errors. These options work like, checking for disk and file system errors and repairing them. You can perform a check from within Mac OS X, but it may sometimes be necessary to use recovery mode to fix problems. In a worst-case scenario, you may have to manually run fsck commands from a terminal in single-user mode. Use “First Aid” in the Disk Utility You can perform a disk health check from the Disk Utility application included with Mac OS X. Apple updated this utility’s interface on Mac OS X 10.11 El Capitan, so it’ll look a bit different from the screenshots below if you’re still using and older version of Mac OS X.
To launch it, you can press Command+Space to open, type “Disk Utility”, and press Enter. Or, you can navigate to your Applications folder, double-click the “Utilities” folder, and double-click the “Disk Utility” shortcut. In the Disk Utility application, select the disk or partition you want to check — the system partition is named “Macintosh HD” by default — and click the “First Aid” button. You can either run the First Aid function on an entire disk, or an individual partition on that disk. It depends which you select in the sidebar. Click “Run” and your Mac will check the disk you selected for errors. If it finds any errors, it will attempt to automatically fix them for you.
You can click the “Show Details” drop-down message to view detailed information about any errors it encounters. You’ll see messages like “Storage system check exit code is 0” and “File system check exit code is 0” here. An exit code of “0” is a good thing, and means no errors were found. Boot into Safe Mode RELATED: One simple way to fix such errors is to.
Safe Mode, sometimes called “Safe Boot,” contains an automatic startup check and repair that can fix these problems. To do this, restart your Mac and hold “Shift” while it’s booting. Sign in with your password and your Mac will then check your disks. This will make the login process take longer than normal, so be patient. When it’s done logging in and you see a desktop, the disk check is done.
You can reboot your Mac at this point. Run First Aid in Recovery Mode RELATED: Ideally, that should be the end of it — especially if you used the safe mode trick above.
However, in some cases, your Mac may find disk or file system problems and be unable to repair them when you perform the above steps. This is because it’s running in “live mode” — examining the disk while the operating system is running from it.
It can’t make changes to that system drive while it’s running from it. The solution is to. From there, you can use Disk Utility in the same way. Your Mac will be able to fix errors on your system drive from recovery mode. To do this, restart your Mac.
Press and hold the “Command+R” keys while it’s booting. You’ll see a progress bar appear, and you can release the keys after you do.
Your Mac will load straight into recovery mode. (If recovery mode doesn’t appear, restart your Mac and try pressing the keys again.) In OS X Recovery, click the “Disk Utility” shortcut to launch the Disk Utility here. Select the drive or partition you need to repair and click the “First Aid” button.
The Disk Utility interface is the same one you’ll see on your Mac OS X desktop, but run it from here and it’ll be able to repair problems with your system drive. Use fsck in Single-User Mode In some cases, even Safe Mode or Disk Utility in OS X Recovery won’t be enough to fix problems. You may need to boot your Mac into single-user mode and run the fsck (file system check) command the old-fashioned way. You don’t need to do this if any of the above steps worked.
This is the thing you should try last, as Disk Utility in the recovery environment may work better and be more capable. To do this, start your Mac in single-user mode. Restart it, and then press and hold the Command+S keys while it boots. You’ll enter single-user mode, which will provide you with a text-mode terminal. Type the following command into the terminal and press Enter to start a file system check: /sbin/fsck -fy The command will run through several phases of checks. When it’s done, you’ll see a message saying “.
The volume name appears to be OK” if everything is fine. If it found problems, you’ll see a “. FILE SYSTEM WAS MODIFIED.” message. This indicates the fsck command found and fixed problems. The fsck command may find additional errors after repairing the first batch of errors, so Apple recommends you run the fsck command again if it found and fixed problems. Run the above fsck command over and over until you see a “. The volume name appears to be OK” message.
When the fsck command says your disk is okay, type the following command at the terminal and press Enter: reboot Your Mac will reboot, returning you to the usual login screen. The above steps should only be necessary if you’re experiencing errors with your Mac. Assuming everything is fine, you don’t need to regularly perform disk first-aid checks. However, if you do want to run a check, you can just do it with Disk Utility from within Mac OS X. You don’t need to reboot into any other environments unless there’s an error on a system drive you need to fix.
