How to Transfer Files to Your Toshiba External Hard Drive on Your Mac. You should know that only a Toshiba drive formatted as Mac OS Extended (Journaled). Or as ExFAT can have files transferred without driver software on your Mac. Mac OS Extended (Journaled) is the native file system your Mac uses. Dec 26, 2017 You’ll now see your list of hard drives. Click your primary drive, then click “Erase” If you’re wiping a mechanical drive, click “Security Options” in the window that pops up. (If your Mac has a solid state drive, you can skip this part: your SSD will already securely erase files thanks to TRIM. You still need to wipe the drive.
The bootable Mac OS X Snow Leopard Install DVD-ROM is important if your Mac ever refuses to boot like normal. If you don’t have a bootable DVD-ROM — preferably a Mac OS X Snow Leopard Install DVD-ROM — call Apple or your Apple dealer to arrange for a replacement.
To boot your Mac from a DVD-ROM installation disc, follow these steps:
- Insert the Mac OS X Install DVD into the DVD drive.If your Mac uses a tray to hold the DVD, make sure that it retracts and that the disc is in.If you have a tray-loading DVD-ROM drive and it’s closed, you can get it to open by restarting (or starting up) your Mac while pressing the mouse button. Continue pressing until the drive tray pops out; then release.
- Shut down or restart your Mac.If you shut it down, wait a few seconds and then start it up the usual way.
- Press and hold down the C key immediately, and keep it pressed until your Mac either boots from the DVD or doesn’t.If it does boot from the DVD-ROM, you see a Welcome screen.If it doesn’t boot, you see a prohibitory sign, spinning-wheel-of-death, or kernel panic alert. . . anything but the first screen of the Mac OS X Installer, the login window, or the Finder. Any of those is your cue to try Step 4.
- If your Mac doesn’t boot after Step 3, hold down the Option key while booting to display the built-in Startup Manager.Use the built-in Startup Manager when you boot from a DVD.It displays icons for any bootable discs that it sees and allows you to select one (including the installation DVD).
- Click the DVD-ROM icon to select it, and then press Return or Enter to boot from it.This technique is quite useful if your usual boot disk is damaged or having an identity crisis during startup.
If you can’t boot from DVD then either you just installed something new that’s aggravating your Mac, or your Mac needs to go in for repairs (usually to an Apple dealer).
To get your Mac up and running again, you can try any of the following:

- Call the tech-support hotline: Before you drag it down to the shop, try calling 1-800-SOS-APPL, the Apple Tech Support hotline. The service representatives there may be able to suggest something else that you can try. If your Mac is still under warranty, it’s even free.
- Ask a local user group for help: Another thing you might consider is contacting your local Macintosh user group. You can find a group of Mac users near you by visiting Apple’s User Group Web pages.
- Try Dr. Mac Consulting: You can check out consulting services or call 408-627-7577. A team of expert troubleshooters does nothing but provide technical help and training to Mac users, via telephone, e-mail, and/or Internet-enabled remote-control software.
- Check whether you have RAM issues: If you have problems immediately after installing random-access memory (RAM) — or any new hardware, for that matter — double-check that the RAM chips are properly seated in their sockets. (Warning: Don’t forget to shut down your Mac first.) With the power off and your Mac unplugged, remove and reinsert the RAM chips to make sure they’re seated properly. If you still have problems, remove the RAM chips temporarily and see whether the problem still exists.Follow the installation instructions that came with the RAM chips — or the ones in the booklet that came with your Mac. But even if they don’t say to get rid of the static spark, you should (by using an antistatic strap available from most RAM sellers or by touching an appropriate surface, such as the power-supply case inside your Mac) before you handle RAM chips.
These advanced steps are primarily for system administrators and others who are familiar with the command line. You don't need a bootable installer to upgrade macOS or reinstall macOS, but it can be useful when you want to install on multiple computers without downloading the installer each time.
Download macOS
Find the appropriate download link in the upgrade instructions for each macOS version:
macOS Catalina, macOS Mojave, ormacOS High Sierra
Installers for each of these macOS versions download directly to your Applications folder as an app named Install macOS Catalina, Install macOS Mojave, or Install macOS High Sierra. If the installer opens after downloading, quit it without continuing installation. Important: To get the correct installer, download from a Mac that is using macOS Sierra 10.12.5 or later, or El Capitan 10.11.6. Enterprise administrators, please download from Apple, not a locally hosted software-update server.

OS X El Capitan
El Capitan downloads as a disk image. On a Mac that is compatible with El Capitan, open the disk image and run the installer within, named InstallMacOSX.pkg. It installs an app named Install OS X El Capitan into your Applications folder. You will create the bootable installer from this app, not from the disk image or .pkg installer.

Use the 'createinstallmedia' command in Terminal
- Connect the USB flash drive or other volume that you're using for the bootable installer. Make sure that it has at least 12GB of available storage and is formatted as Mac OS Extended.
- Open Terminal, which is in the Utilities folder of your Applications folder.
- Type or paste one of the following commands in Terminal. These assume that the installer is still in your Applications folder, and MyVolume is the name of the USB flash drive or other volume you're using. If it has a different name, replace
MyVolume
in these commands with the name of your volume.
Catalina:*
Mojave:*
High Sierra:*
El Capitan: - Press Return after typing the command.
- When prompted, type your administrator password and press Return again. Terminal doesn't show any characters as you type your password.
- When prompted, type
Y
to confirm that you want to erase the volume, then press Return. Terminal shows the progress as the bootable installer is created. - When Terminal says that it's done, the volume will have the same name as the installer you downloaded, such as Install macOS Catalina. You can now quit Terminal and eject the volume.
* If your Mac is using macOS Sierra or earlier, include the
--applicationpath
argument, similar to the way this argument is used in the command for El Capitan.Use the bootable installer

After creating the bootable installer, follow these steps to use it:
- Plug the bootable installer into a compatible Mac.
- Use Startup Manager or Startup Disk preferences to select the bootable installer as the startup disk, then start up from it. Your Mac will start up to macOS Recovery.
Learn about selecting a startup disk, including what to do if your Mac doesn't start up from it. - Choose your language, if prompted.
- A bootable installer doesn't download macOS from the Internet, but it does require the Internet to get information specific to your Mac model, such as firmware updates. If you need to connect to a Wi-Fi network, use the Wi-Fi menu in the menu bar.
- Select Install macOS (or Install OS X) from the Utilities window, then click Continue and follow the onscreen instructions.
