Administrator: An administrator can add and manage other users, install apps, and change settings. The new user you create when you first set up your Mac is an administrator. Your Mac can have multiple administrators. You can create new ones, and convert standard users to administrators.
Don’t set up automatic login for an administrator. If you do, someone could simply restart your Mac and gain access with administrator privileges.
To keep your Mac secure, don’t share administrator names and passwords. Standard: Standard users are set up by an administrator.
Standard users can install apps and change their own settings, but can’t add other users or change other users’ settings. Managed with Parental Controls: Users who are managed with parental controls can access only the apps and content specified by the administrator managing the user. The administrator can restrict the user’s contacts and website access, and place time limits on computer use.
Sharing Only: Sharing-only users can access shared files remotely, but can’t log in to or change settings on the computer. To give the user permission to access your shared files or screen, you may need to change settings in the File Sharing, Screen Sharing, or Remote Management panes of Sharing preferences.
For more information, see. For more information about the options for each type of user, click the Help button in the lower-left corner of the dialog. Enter a full name for the new user. An account name is generated automatically. To use a different account name, enter it now—you can’t change it later. Enter a password for the user, then enter it again to verify. Enter a password hint to help the user remember their password.

Click Create User. Depending on the type of user you create, you can also do any of the following:. For an administrator, select “Allow user to administer this computer.”. For a child or other managed user, select “Enable parental controls.” Click Open Parental Controls, then set up restrictions for the user. For more information, see.
Use Sharing preferences to specify whether the user can. If your Mac has Touch ID, a new user can add a fingerprint after logging in to the Mac.
The user can then use Touch ID to unlock the Mac and password-protected items, and purchase items from the iTunes Store, App Store, and iBooks Store using their Apple ID. For more information, see. A group allows multiple users to have the same access privileges. For example, you can grant a group specific access privileges for a folder or a file, and all members of the group have access. You can also assign a group specific access privileges for each of your shared folders.
Choose Apple menu System Preferences, then click Users & Groups. Click the lock icon to unlock it, then enter an administrator name and password. Click the Add button below the list of users. Click the New Account pop-up menu, then choose Group.

Guests don’t need a password to log in. Guests can’t change user or computer settings. Guests can’t log in remotely when remote login is turned on in Sharing preferences.
Files created by a guest are stored in a temporary folder, but that folder and its contents are deleted when the guest logs out. Guest access works with the Find My Mac feature of iCloud to help you find your Mac if you lose it. You can locate your Mac if someone finds it, logs in as a guest, and then uses Safari to access the Internet. Note: If FileVault is turned on, guests can only use Safari and can’t access your encrypted disk or create files. Choose Apple menu System Preferences, then click Users & Groups.

R will ask you to select a CRAN mirror; pick the first, '0-Cloud' mirror, or a mirror site near you. Once it is installed, to load the Rcmdr package, simply issue the command library(Rcmdr) at the R command prompt and press return. When you first load the Rcmdr package, it will offer to download and install missing dependencies; allow it to do so. Suppressing 'app nap': Under Mac OS X 10.9 ('Mavericks') or later, the R Commander may slow down or occasionally hesitate to display a menu as your session progresses. This behaviour is due to OS X 10.9 or later saving power by going into 'nap' mode when the R.app window is not visible. I am aware of several solutions (beyond always inconveniently insuring that the top of the R.app window is visible).
The first solution is simplest. (1) You can suppress app nap via the R Commander Tools - Manage Mac OS X app nap for R.app menu.
Select the radio button to set app nap off in the resulting dialog box. This setting is permanent across R.app sessions until you change it.
(2) You can avoid the problem by running R in a terminal window rather than using R.app. There really is no reason to prefer running the R Commander in R.app, so using R from a terminal should be perfectly fine.
Open the Utilities subfolder inside the Applications folder on your Mac. Click on Terminal.app to open a terminal window. At the Unix command prompt in the terminal window, type R and press the enter (or return) key.
On my Mac, the Unix command prompt looks like this: john-fox-mbp: jfox$. Once R starts up, you'll see the usual initial messages, followed by the R command prompt. As usual, type library(Rcmdr) at the R prompt and press the enter key. After you exit from the R Commander, you can safely close the terminal window, whether or not you have exited from R. (3) You can prevent your computer from napping when R.app is running, even if it's not visible, by right-clicking (or control-clicking) on R.app in the Applications folder in the Finder, and selecting Get Info from the context menu. Check the box next to Prevent App Nap. The change is permanent until you reverse it by unchecking the box.
This solution only works with the snowleopard build of R.app. (4) Enter the following command in a Mac terminal window at the Unix command prompt: defaults write org.R-project.R NSAppSleepDisabled -bool YES This is the manual equivalent of solution (1), and is permanent until reversed. Mac OS X Trouble-shooting Occasionally, the Rcmdr package will fail to load properly in Mac OS X. When this problem occurs, the cause is almost always the failure of the tcltk package to load -The Rcmdr package depends on the tcltk package. You can confirm this diagnosis by trying to load the tcltk package directly, in a fresh R session, issuing the command library(tcltk)at the R command prompt.
If you are running R version 3.1.2, the tcltk package may fail to load with a message like the following. This is due to a bug in R 3.1.2, which assumes that the otool utility is installed on your system, and which fails if it is not. The simplest fix is to install a newer version of R. Error:.onLoad failed in loadNamespace for 'tcltk', details: call: system2('otool', c('-L', shQuote(DLL)), stdout = TRUE) error: error in running command Error: package or namespace load failed for ‘tcltk’ sh: otool: command not found.
If the tcltk package fails to load with a message like the following, then your system has an old version of X-Windows that is incompatible with the version of Tcl/Tk for X-Windows that's distributed with R. The probable solution is to run Mac OS Software Update, as suggested in the steps above - or just install the current version of XQuartz.
