Update Mac From Terminal



Terminal

To update macOS from the command line, first launch Terminal, which can be found in the Applications/Utilities folder. This will open a Terminal window and a command prompt for you to begin typing. What is eDEX-UI for Mac eDEX-UI is a fullscreen, cross-platform terminal emulator and system monitor that looks and feels like a sci-fi computer interface Heavily inspired from the TRON Legacy movie effects (especially the Board Room sequence), the eDEX-UI project was originally meant to be 'DEX-UI with less « art » and more « distributable.

Xcode is the tool developers use to build apps for the Apple ecosystem – MacOS, iOS, and all things Apple.

This guide will walk you through how to successfully install Xcode onto your Mac, from start to finish.

Here are some handy tips to know before you get started:

  • Xcode only runs on a mac. If you are on a PC, sadly you won't be able to use Xcode.
  • You'll need a good, stable internet connection. The latest version is around 8 gigabytes in size.
  • Be sure to have at least 30 gigabytes of free space on your computer. The latest .xip file (v11.4.1 at the time of writing) is ~8 gigabytes zipped. When you unzip it, that's another 17 gigabytes. Then you'll need the command line tool, which is yet another 1.5 gigabytes.

Here's an overview of the steps to install Xcode

  1. Download Xcode
  2. Install the command line tool
  3. Open the new version
  4. Delete files

Note that I have listed some Terminal commands in the steps below. These commands can be typed into your present working directory. This means that you don't need to navigate to any particular folder.

If you really want to, you can first type cd before typing the commands in the below steps. This will return you back to the home folder.

Step #1: Download Xcode

There are two ways to do this. For the latest version and a theoretically 'easy' installation, you can use the App Store. I don't recommend this option.

Update Mac From Terminal

I prefer to use the developer site. This comes with the bonus option of being able to download any version you'd like.

Option #1: Download via the App Store for the latest version (not my preferred option)

Upgrade os x to high sierra. In theory, this should be a seamless and pain-free process. But if the installation fails for any reason on the last step, it is very hard to troubleshoot.

There are a few reasons for failure, and no easy way to know which is the underlying cause. If you do encounter a failure, you will need to re-download the entire file again each time you try to fix the failure. As the latest version is 8 gigabytes, I didn't much enjoy this approach.

But if you're feeling brave, here are the steps:

  • Open the App Store on your mac
  • Sign in
  • Search for Xcode
  • Click install or update

Option 2: Download via the Developer site for a specific version (my preferred option)

  1. Head to the 'more' section of the Apple developer website
  2. Sign in with your iTunes account id
  3. Type in the version that you'd like, and download the Xcode_x_x_x.xip file. Keep in mind that Xcode 11.4.1 is 8 gigabytes, so this will take awhile depending on your internet connection.
  4. Once the file is downloaded, click on .xip to extract it. Your laptop will extract it to the same folder you downloaded it to. This extraction process is automatic. You don't need to do anything more after you click on the .xip file. This step will take a few minutes.
  5. [Optional] Once extracted, rename the application to “Xcode11.x.x” if you are using multiple versions.
  6. Drag application to the Applications folder
  7. [Optional] Set the new Xcode version as the default. Open Terminal and type sudo xcode-select -switch /Applications/Xcodex.x.x.app . Replace x.x.x with the version number. For example: Xcode11.4.1.app. You will need to enter in your computer admin password. I'm pretty sure this will update the default Xcode version for all users on your computer, so best to check with other users first

Step #2: Install the command line tool (CLT)

If you have multiple users on your computer, you will need to update the CLT for each user.

Download .dmg

To update the CLT, go to app developer website and download the command line tool .dmg.

If you have never installed Xcode before, you may be able to update with your Terminal by typing in xcode-select --install instead of visiting the developer website.

But if you have an existing version of Xcode installed on your machine, you'll probably see this error:

This means you'll need to go to the developer website instead.

Installing the CLT

When the .dmg has finished downloaded, double click the file to open it. This will open a little window that looks like this:

Double click the box and follow the prompts to install the CLT. It will take a few minutes to complete.

It may ask you at the end of the installation whether you want to move this to the trash bin. When it does this, it's talking about moving the .dmg file to the trash bin. Since you should no longer need this file. I always say yes to this.

Step #3: Open Xcode

Open the Applications folder and open the new version of Xcode. If you renamed Xcode, make sure you open the correct application

Xcode may prompt you to install additional components. Click install. This will take a few minutes.

While it's installing, check that your default Xcode version is the one you just downloaded:

  • Open Terminal
  • Type brew config
  • You should see “CLT” and “Xcode” versions, as well as everything else. This should reflect the version that you have just downloaded. In my case, I downloaded Xcode 11.4.1.

Once the components are installed, Xcode will launch. You should be able to pick up your old projects and continue where you left off seamlessly*.

*Note that if you use any proxy tools, such as Charles, you will need to re-install those certificates in your simulator again.

If you encounter any errors while trying to build or run a project, check which device you are trying to launch. The new version may not remember the device you were using before. If so, click on the device and choose 'Add additional simulators' from the drop down menu to add the device you want.

Step #4. Delete the files

If you don't need the older versions of Xcode on your computer, you can uninstall them and get some hard drive space back.

You can also delete the .xip file of the version you just downloaded, as well as the CLT.dmg file.

That's everything. I hope this has helped you successfully install Xcode. Have fun with it!

Most new PCs don't come with DVD drives anymore. So it can be a pain to install Windows on a new computer.

Luckily, Microsoft makes a tool that you can use to install Windows from a USB storage drive (or 'thumbdrive' as they are often called).

But what if you don't have a second PC for setting up that USB storage drive in the first place?

In this tutorial we'll show you how you can set this up from a Mac.

You can download the ISO file straight from Windows. That's right - everything we're going to do here is 100% legal and sanctioned by Microsoft.

If you want an English-language version of the latest update of Windows 10, you can download the ISO here.

If you have a relatively new computer, you probably want the 64-bit version. If you're not sure, go with the 32-bit version to be safe.

Mac

If you want a non-English-language version of Windows, or want to get an older update version, download the ISO here instead.

The ISO file is only about 5 gigabytes, but I recommend you use a USB drive with at least 16 gigabytes of space just in case Windows needs more space during the installation process.

I bought a 32 gigabyte USB drive at Walmart for only $3, so this shouldn't be very expensive.

Stick your USB drive into your Mac. Then open your terminal. You can do this using MacOS Spotlight by pressing both the ⌘ and Space bar at the same time, then typing 'terminal' and hitting enter.

Don't be intimidated by the command line interface. I'm going to tell you exactly which commands to enter.

Open Mac Spotlight using the ⌘ + space keyboard shortcut. Then type the word 'terminal' and select Terminal from the dropdown list.

Paste the following command into your terminal and hit enter:

diskutil list

You will see output like this (note - your Mac's terminal may be black text on a white background if you haven't customized it).

Mac

Copy the text I point to here. It will probably be something like

/dev/disk2.

Next format your USB drive to Windows FAT32 format. This is a format that Windows 10 will recognize.

Update Mac From Terminal Linux

Note that you should replace the disk2 with the name of the your drive from step 3 if it wasn't disk2. (It may be disk3 or disk4).

Run this command using the correct disk number for your USB:

diskutil eraseDisk MS-DOS 'WIN10' GPT /dev/disk2

Then you'll see terminal output like this.

Mac Update Java From Terminal

This will probably only take about 20 seconds on a newer computer, but may take longer on an older computer.

Note that for some hardware, you may instead need to run this command, which uses the MBR format for partitioning instead of GPT. Come back and try this command if step 7 fails, then redo steps 5, 6, and 7:

Now we're going to prep our downloaded ISO file so we can copy it over to our USB drive.

You will need to check where your downloaded Windows 10 ISO file is and use that. But your file is probably located in your ~/Downloads folder with a name of Win10_1903_V1_English_x64.iso.

Mac Update Java From Terminal

hdiutil mount ~/Downloads/Win10_1903_V1_English_x64.iso

Update April 2020: One of the files in the Windows 10 ISO – install.wim – is now too large to copy over to a FAT-32 formatted USB drive. So I'll show you how to copy it over separately.

Thank you to @alexlubbock for coming up with this workaround.

First run this command to copy over everything but that file:

rsync -vha --exclude=sources/install.wim /Volumes/CCCOMA_X64FRE_EN-US_DV9/* /Volumes/WIN10

Then run this command to install Homebrew (if you don't have it installed on your Mac yet):

Update Mac Name Terminal

/usr/bin/ruby -e '$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)'

Then use Homebrew to install a tool called wimlib with this terminal command:

brew install wimlib

Then go ahead and create the directory that you're going to write the files into:

mkdir /Volumes/WIN10/sources

Then run this command. Note that this process may take several hours, you may see 0% progress until it finishes. Don't abort it. It will use wimlib to split the install.wim file into 2 files less than 4 GB each (I use 3.8 GB in the following command), then copy them over to your USB:

wimlib-imagex split /Volumes/CCCOMA_X64FRE_EN-US_DV9/sources/install.wim /Volumes/WIN10/sources/install.swm 3800

How To Update Macos From Terminal

Once that's done, you can eject your USB from your Mac inside Finder.

Congratulations - your computer now should boot directly from your USB drive. If it doesn't, you may need to check your new PC's BIOS and change the boot order to boot from your USB drive.

Update Mac From Terminal Mac

Windows will pop up a screen and start the installation process.

Enjoy your new PC, and your newly-installed copy of Windows.
