For example, if you want to easily install favorite command line tools on a Mac like cask, htop, wget, nmap, tree, irssi, links, colordiff, or virtually any other familiar unix command line utility, you can do so with a simple command. Homebrew downloads and builds the package for you.

Several tools are available for Macintosh System Administrators, mostly in the form of command-line shell scripts to be run from the Terminal application. Please read the comments in each script for descriptions and directions.

Running BOINC as a daemon or system service

Answer As OSX is based on UNIX you need to type in the following command from a terminal prompt ifconfig -a This has been tested on: OSX Mavericks, Yosemite, EL Capitan. This command should also work for other versions of OSX Please Note: This is a “QUICK SUPPORT” article. The information contained herein is provided. Create a new file from a template or theme. Shift + Command + P. Expand or minimize the ribbon. Command + Option + R. Open a file or item. Close a file or item. Quit the current application. Hide the current application.

Make_BOINC_Service.sh is a command-line shell script to set up the BOINC Client to run as a daemon at system startup. It can be used with either full GUI installations (BOINC Manager) or the stand-alone BOINC Client. (If you don't use the boinc daemon that came with the GUI installation, you should check the /Library/LaunchDaemons/edu.berkeley.boinc file that the Make_BOINC_Service.sh script generates for double slashes (//) and remove them if necessary.)

When run as a daemon:

• The BOINC Client always runs even when no user is logged in. However, it still observes the Activity settings as set by the Manager or the boinc_cmd application (Run always, Run based on preferences, Suspend, Snooze; Network activity always available, Network activity based on preferences, Network activity suspended.)
• Quitting the BOINC Manager will not cause the Client to exit.
• Most projects have upgraded their graphics to version 6 and will display graphics properly on BOINC version 6.2 and later even when running as a daemon. However, older style (version 5) application graphics (including screen saver graphics) are not available when the Client runs as a daemon.
• The BOINC Client may not successfully detect the presence of a GPU, so BOINC Project applications may not be able to use the GPU.
• The following apply to the full GUI installation (BOINC Manager):
  • You may need BOINC version 6.2 or later to work properly as a daemon.
  • Normally, BOINC Manager starts up automatically when each user logs in. You can change this as explained below.
  • If you wish to block some users from using BOINC Manager, move it out of the /Applications directory into a directory with restricted permissions. Due to the Manager's internal permissions, you can move it but cannot copy it. See Client security and sandboxing for more information.

Disabling auto-launch of BOINC Manager

By default, BOINC Manager starts up automatically when each user logs in. You can override this behavior by removing the BOINC Manager Login Item for selected users, either via the Accounts System Preferences panel or by creating a nologinitems.txt file in the BOINC Data folder. This should be a plain text file containing a list of users to be excluded from auto-launch, one user name per line.

An easy way to create this file is to type the following in terminal, then edit the file to remove unwanted entries:

After creating this file, run the installer. The installer will delete the Login Item for each user listed in the file. Entries which are not names of actual users are ignored (e.g., Shared, Deleted Users.)

Using BOINC's security features with the stand-alone BOINC Client

Beginning with version 5.5.4, the Macintosh BOINC Manager Installer implements additional security to protect your computer data from potential theft or accidental or malicious damage by limiting BOINC projects' access to your system and data, as described in Client security and sandboxing. We recommend that stand-alone BOINC Client installations also take advantage of this protection. You can do this by running the Mac_SA_Secure.sh command-line shell script after installing the stand-alone Client, and again any time you upgrade the Client.

Although we don't recommend it, you can remove these protections by running the Mac_SA_Insecure.sh script.

Moving BOINC Manager or BOINC Data Folder to a Different Drive

It is possible to run BOINC on the Mac with the BOINC Manager application or the BOINC Data folder on a drive other than the boot drive. This is complicated a bit by the need to set up the special permissions for BOINC's sandbox security, but it can be done. These instructions are provided with no warranty; use them at your own risk.

Here are instructions for moving both the application and the data (you can move either or both):

Syntax Tool For Mac Os

Shortcut: instead of typing a path in the Terminal application, you can drag a folder or file from a Finder window onto the Terminal window. If you do this, omit the quotation marks around the path!

[1] Quit BOINC.

[2] If you only want to move the BOINC Manager application, skip to step [4].

Copy the BOINC Data directory from the '/Library/Application Support/' directory to the desired drive. Rename the original BOINC Data directory or move it to a different directory on your boot drive as a backup safety measure. In any case, you must now not have a '/Library/Application Support/BOINC Data' directory before the next step.

[3] Create a symbolic link to the new BOINC Data directory in place of the old one. Enter the following in the Terminal application:

Substituting your new path for {newDataPath}; for example: '/Volumes/newDrive/myData'.

[4] If you only want to move the BOINC Data, skip to step [5].

Copy BOINCManager.app from '/Applications/BOINCManager.app' to the desired drive, and move the original into the trash. (The Finder may not show the filename extension '.app').

Create a symbolic link to the new copy in place of the old one. Enter the following in the Terminal application:

Substituting your new path for {newAppPath}; for example: '/Volumes/newDrive/myApps'

[5] IMPORTANT: you must create symbolic links. Macintosh aliases created with the Finder will not work!

Run the script Mac_SA_Secure.sh to set up proper permissions at the new locations. Enter the following in the Terminal application:

where {newDataPath} is as above and {path} is the path to the Mac_SA_Secure.sh script. (As before, you can drag the Mac_SA_Secure.sh file from a Finder window onto the Terminal window instead of typing its path.)

[6] Relaunch BOINC.

IMPORTANT Unit 3earth systemsmr. macs 6th grade. : Each time you run the installer, you will need to repeat this. You may also need to repeat it after upgrading to a new version of Mac OSX. The installer will replace the symbolic link to the Manager with the new Manager, and will replace the symbolic link to the BOINC Data directory with a new initialized BOINC Data directory with no projects attached. You must:

• cancel out of the 'Attach to Project' dialog
• quit BOINC
• move that new initialized BOINC Data directory to the trash
• repeat steps [2] through [4].

Note: according to this discussion, the target drive must have 'Owners Enabled' set.

For safety, always make a backup copy of your BOINC Data before performing these steps.

Selecting which users may run BOINC Manager

Due to new restrictions imposed by OS 10.6 Snow Leopard, there has been a change in BOINC's security implementation. Non-administrative users can no longer run BOINC Manager unless they are added to group boinc_master.

As of BOINC 6.10.5, the BOINC installer asks whether or not you wish to add all non-admin users to group boinc_master. (As before, the installer automatically adds all users with administrative privileges [i.e., users who are members of group admin] to group boinc_master.)

If you need more selective control over which users should be in group boinc_master, you can use the command-line tool AddRemoveUser.

To add user1, user2 and user3 to group boinc_master, enter the following in the Terminal application:

where {path} is the path to the AddRemoveUser application.This also sets a login item for each specified user so that BOINC Manager will start automatically when that user logs in.

You can also use:

This is the same as the -a option and also sets BOINC as the screensaver for the specified users.

To remove user1, user2 and user3 from group boinc_master, enter the following in the Terminal application:

This also removes the BOINCManager login item for each specified user. If any of the specified users had BOINC set as their screensaver, it will change their screensaver to Flurry.

Installing BOINC on a Mac using the command line

In some situations, such as remote or automated installs, it is more convenient to install BOINC Manager via the command line instead of the GUI. But there is no way to respond to dialogs during a command-line install.

Apple's command-line installer sets the following environment variable:

The postinstall script, postupgrade script, and this Postinstall.app detect this environment variable and do the following:

• Redirect the Postinstall.app log output to a file /tmp/BOINCInstallLog.txt.
• Suppress the 2 dialogs (asking whether to allow non-admin users to manage BOINC and whether to use the BOINC screensaver.)
• test for the existence of a file /tmp/nonadminusersok.txt; if the file exists, allow non-administrative users to run BOINC Manager.
• test for the existence of a file /tmp/setboincsaver.txt; if the file exists, set BOINC as the screensaver for all BOINC users.

The BOINC installer package to be used for command line installs can be found embedded inside the GUI BOINC Installer application at:

Example: To install on a remote Mac from the command line, allowing non-admin users to run the BOINC Manager and setting BOINC as the screensaver:First SCP the 'BOINC.pkg' to the remote Mac's /tmp directory, then SSh into the remote Mac and enter the following:

1. What Is Snipping?

Have you ever wanted to capture a screenshot of your Mac’s screen, but don’t know how? It’s a common issue faced by many Mac users every day snip it for Mac. Thankfully, there is a solution — it’s called snipping tool Mac.

If you don’t know how to snip on Mac, keep reading for a full guide about learning to use a Mac.

What Is Snipping?

Snipping tool Mac is a specific way to take a screenshot on your computer (Mac in this case).

Snipping is different than an average screenshot. When you take a screenshot, you’re left with an image of the full computer screen. This includes the entire user interface, from the top-bar to the hot-bar at the bottom of the screen.

When you snip, you can choose a specific portion of the screen to take a shot of. Usually, this is done by clicking and dragging your mouse across the area you want to capture. This lets you take screenshots of smaller portions of your screen, and whole-screen-shots without things like the hot-bar entering the picture.

How to Snip on Mac?

There are a few different ways you can snip on Mac. Fortunately for everyone, none of them are very complex.

Here are a few of the many ways you can learn how to snip on Mac and get the tips to start using a Mac like the Mac Pro you are.

Use Mac’s Built-In Snipping Tool Mac

The easiest way to take a snip on Mac is to use the built-in Mac snipping tool.

Mac’s snipping tool isn’t an application, but rather a keyboard shortcut. Most people know you can take a screenshot by hitting ‘shift + command + 3.’ What most people don’t know is you can also take a snip by hitting ‘shift + command + 4.’

Once you hit ‘shift + command + 4’ your mouse pointer will turn into a crosshair. With the crosshair, click and drag a square over the area you want to capture. You can snip as large or small an area as you desire.

Once you’ve got the area you wish to snip covered, simply release the mouse button and you’re done. You can view your snips and screenshots by hitting ‘shift + command + 5’ to open the Screenshot app.

Shift + Command + 5

By just clicking ‘Shift + Command + 5’ you get the Screenshot app/toolbar.

At the bottom of the screen, you’ll see options to capture the whole screen, a selected window or portion, or even record areas of the screen. Under ‘Options’ there are timer selections, and pointer visibility options among other things.

You can use this bar to take more control over your snips. It doesn’t offer anything radically different, but is great for those who want screen recording.
