TERMINAL 64 Mac OS

Most users use Disk Utility to erase a disk or hard drive. But some Mac users might need to erase them from the command line on Mac OS. To do that, the only thing you need is a bit of precise syntax to make sure that you are erasing the proper disk.

Here's the configuration file approach for always booting into 64-bit. This is the best way to make your Mac always start up 64 bit as the only thing necessary is to alter one line of a configuration file. You can do that by opening the Terminal and entering the following line. You can also copy/paste it from here into the Terminal window. Mac OS X Server 10.6, Mac OS X 10.6, Mac Pro (Mid 2010) Method 1 - Startup key combination (for current startup only) If your Mac uses the 32-bit kernel by default, but supports the 64-bit kernel, you can start up using the 64-bit kernel by holding the 6 and 4 keys during startup. (Above is the Terminal command for enabling 64-bit mode in macOS 10.13.4.) 3) Restart the Mac When the Mac has been restarted, no 32-bit process will launch, including 32-bit apps, web plugins, preference panes, software components, or background tasks and processes. Terminal provides a command line interface to control the UNIX-based operating system that lurks below macOS (or Mac OS X). Here's everything you need to know about Terminal, and what it can do. For Python 2.7, open the Terminal.app or iTerm2 terminal application and then enter the following: bash / Downloads / Anaconda2 - 2019.10 - MacOSX - x8664.

Here I'll show you how you can erase and format a disk using the command line.

Working with Terminal

Start off by running the following command in the command line: Diskutil list

This is going to list all the mounted drives on your Mac.

Once you have found the proper drive to erase, just copy its identifier so you can use it for the next command. Then pick a name and a system format type. This is the syntax we need: Diskutil eraseDisk FILESYSTEM DISKNAME DISKIDENTIFIER

Let’s say the disk I want to erase has “/dev/disk5s2” as its identifier and I’m going to use Mac OS Extended Journaled (JHFS+) as the system format type and name it “Empty”. The syntax is going to look like this: Diskutil eraseDisk JHFS+ Empty /dev/disk5s2

It’s important to keep in mind that if you run the eraseDisk command, the target disk is going to lose all its data, so make sure you are erasing the proper disk.

If you need different system format types, here are a few references you could use instead of JHFS+:

  • Mac OS Extended: HFS+
  • MS-DOS fat32: FAT32
  • ExFAT: ExFAT

The Terminal is the easiest way to access the Unix promptin Mac OS X. If you're familiar with Unix, youmay recognize its similarity to xterm implementations inLinux and other Unix-like operating systems; if not, theTerminal's non-graphical environment may be intimidating. However, itallows you to use built-in command line programs such asSSH and SFTP, and is required for some advancedMac OS X tasks.
