Step 1: Insert the macOS bootable USB drive on a USB port of Mac computer. Step 2: Shut down the Mac and wait for 1-2 minutes. This will make sure the Mac is powered off. Step 3: Hold the Power and Option key simultaneously for 15 seconds. This will bring up the Startup Manager on Mac. Ctrl Home and Ctrl End will go to start and end of document Shift Ctrl Home and Shift Ctrl End will select to start and end of document Note that you need to reboot after creating this file for it to take effect. Also make sure your editor does not append TXT to the end of it! CTRL-E – this is to go to the end of the line in Bash (set this to the ‘End’ key) The first combo will produce: 005 The second combo will produce: 001. Don’t worry, it works in 10.5.x. This also works in the C Shell (’csh’), so if you are used to using it this will work there as well. When you start up your Mac, the system will generally show a gray Apple logo for a brief period followed by the log-in screen or other user interface elements as the rest of the operating system.

Start up from macOS Recovery

Determine whether you're using a Mac with Apple silicon, then follow the appropriate steps:

Apple silicon

Turn on your Mac and continue to press and hold the power button until you see the startup options window. Click the gear icon labeled Options, then click Continue.

Intel processor

Make sure that your Mac has a connection to the internet. Then turn on your Mac and immediately press and hold Command (⌘)-R until you see an Apple logo or other image.

If you're asked to select a user you know the password for, select the user, click Next, then enter their administrator password.

Reinstall macOS

End To Start Mac Os Sierra

Select Reinstall macOS from the utilities window in macOS Recovery, then click Continue and follow the onscreen instructions.

Follow these guidelines during installation:

• If the installer asks to unlock your disk, enter the password you use to log in to your Mac.
• If the installer doesn't see your disk, or it says that it can't install on your computer or volume, you might need to erase your disk first.
• If the installer offers you the choice between installing on Macintosh HD or Macintosh HD - Data, choose Macintosh HD.
• Allow installation to complete without putting your Mac to sleep or closing its lid. Your Mac might restart and show a progress bar several times, and the screen might be empty for minutes at a time.

End To Start Mac Os Catalina

After installation is complete, your Mac might restart to a setup assistant. If you're selling, trading in, or giving away your Mac, press Command-Q to quit the assistant without completing setup. Then click Shut Down. When the new owner starts up the Mac, they can use their own information to complete setup.

Other macOS installation options

When you install macOS from Recovery, you get the current version of the most recently installed macOS, with some exceptions:

• On an Intel-based Mac: If you use Shift-Option-Command-R during startup, you're offered the macOS that came with your Mac, or the closest version still available. If you use Option-Command-R during startup, in most cases you're offered the latest macOS that is compatible with your Mac. Otherwise you're offered the macOS that came with your Mac, or the closest version still available.
• If the Mac logic board was just replaced, you may be offered only the latest macOS that is compatible with your Mac. If you just erased your entire startup disk, you may be offered only the macOS that came with your Mac, or the closest version still available.

You can also use these methods to install macOS, if the macOS is compatible with your Mac:

• Use the App Store to download and install the latest macOS.
• Use the App Store or a web browser to download and install an earlier macOS.
• Use a USB flash drive or other secondary volume to create a bootable installer.

There are two main ways to install PostgreSQL on mac OS X.

1. Downloading the app file from postgresapp.com.

Using Homebrew

Homebrew can be installed by running the following command in a terminal:

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

If Homebrew is already installed, make sure that it is up to date by running:

brew updatehttps://pop-mac-pearl-soft-bubble-the-os-gkxqr.peatix.com.

Then ensure there are no conflicts or errors using:

https://innovationtorrent.mystrikingly.com/blog/daddy-s-girls-mac-os. brew doctor

Homebrew is a powerful package manager with many uses, including installing and running postgreSQL. This can be done by typing the following command into a terminal:

Now that postgres is installed the default server can be started by running the command:

This will start up a postgres server hosted locally on port 5432. The server will be run out of the directory /usr/local/var/postgres.

It can now be accessed by typing the following command:

This will connect to the server and access the postgres database. Once this is done:

• Schemas and tables can be created
• Data can be loaded and deleted from the database
• Queries can be run

The process should look like this:

This shows that the server has been started and can be connected to.

(Optional) Creating a Custom Data Directory

A custom data directory can also be used for a server. To do this, first create a directory to be used as the server location. For example, create a directory called myData in the home directory:

Once the directory is created, the server can be initialized. This means that we configure the directory and add the necessary files to run the server. To do this run the initdb command as shown:

This will fill the myData directory with files necessary to run the server:

Now that the server is initialized and the log file is created, you can start the server from this directory. To do this use the command and substitute in for the specified values:

The “Data Directory” refers to the directory that was just initialized (in this case myData). The “Log file” is a file that will record server events for later analysis. Generally log files are formatted to contain the date in the file name (e.g. “2018-05-27.log” or “myData-logfile-2018-05-27.log”) and should be stored outside of the database that they are logging so as to avoid unnecessary risks. Log files can be dense to read but are very useful for security and debugging purposes:

The command above will generate a log file like the one shown, start the server, and tie the log file to the server. If a log file is not specified, events will be logged to the terminal:

The server will only start if the port is free. If the default server is running it must first be stopped using the pg_ctl -D /usr/local/var/postgres stop command:

Once started, it can be connected to the same way as before using:

Using PostgreSQL App

To run a server through the postgres app, the first step is to download the program. The app can be downloaded on postgresapp.com. Once the app is downloaded and moved into the applications folder, the app can be opened.

Open the Postgres app:

In order to start the server, click the start button.

This will start the server. Details on the server can be found by opening the server settings:

This interface shows all the essential information regarding the server. It also allows the port to be changed very easily. This is useful because multiple PostgreSQL servers can

Note: To change the port in the terminal, the ‘postgres.conf’ file (which can be found in the data directory) must be edited. This looks like the following:

Using Terminal with the PostgreSQL App

Once the app has been downloaded, command line tools can be used as well. Sphere jenga mac os. These tools can be accessed by typing:

For example, the ‘postgres’ database on the server can be connected to using the psql tool with postgres as an argument:

Rather than typing out the full path each time however, the path can be added to a file that will allow significantly easier access to the tools, allowing the tools be accessed from any directory on the computer. To do this, the following command can be run in the terminal:

Once this is done, the ‘postgres’ database can be accessed by simply typing:
