Mac startup key combinations. To boot your Intel-based Mac into any of the macOS built-in startup modes, you must press and hold one or more keys detailed below after turning on the computer. Press the keys immediately after hearing the startup sound, unless otherwise specified. Manually restart: Power (⎋) Boot from CD/DVD: C.

When you first start using a brand-new Mac or performed a clean install of OS X, you are presented with Setup Assistant, allowing you to create the first user account and specify some initial information, such as keyboard layout and locale.
Under certain circumstances, it can be advantageous to re-run the Setup Assistant. Using some command-line trickery, we can do just this without having to erase and reinstall OS X.
What Setup Assistant Does
Setup Assistant is designed to run on the first boot of a fresh install of OS X, which is why you'll only see it when booting up a a brand-new Mac or one that has been erased and had OS X reinstalled.
Besides options for keyboard layout, time zone and asking if you'd like to register, Setup Assistant also lets you create a new user account. As Setup Assistant assumes the account it is creating to be the first, it is always given administrator privileges.
Why Bother?
There may come a time when you need to set up a second user account on a Mac while attempting to resolve a user account issue. If a Mac has only one user account and it seems to be unable to log in correctly (getting stuck at the login window, for example), having a second account will allow you to access OS X and continue troubleshooting.
By re-running Setup Assistant, we can use the process to create a user account that will automatically have administrator privileges, without having to do so via System Preferences, which we might not be able to access. Embroidery software for mac.
There are other reasons why re-running it can be advantageous, though in my experience, the above has always been the most common reason to do so. Sure, you can create user accounts using a number of commands, but Setup Assistant is just far easier.
.AppleSetupDone
Every time OS X boots, it checks for the existence of a file known as
.AppleSetupDone . This empty file is created after the completion of Setup Assistant. It doesn't exist on a brand-new, out-of-the-box Mac, nor on one that has had a clean installation of OS X.
By removing this file, OS X will assume that Setup Assistant has never been run and will launch it as soon as OS X boots.
How to stop mac background apps from loading. Setup Assistant is also run with root privileges, which is why it can create a new user account with administrator privileges without the need for any authorisation.
Removing .AppleSetupDone
To remove this file, we need to boot the Mac into Single-User Mode. This provides a method of interacting with OS X via the command-line, with full root privileges.
Start up the Mac whilst holding down
⌘-S . After a few moments, you'll see the Mac boot to the command line.
Before continuing, the filesystem must be checked and mounted, so files are't immediately accessible to interact with. To do this, enter the two commands that are displayed within the prompt, one at a time.
The following command will check the filesystem to ensure there are no problems. Enter:
The next command will then mount the filesystem for it to be accessible:
With the filesystem mounted and accessible, it's time to remove the file so OS X will re-run Setup Assistant:
After that, simply enter
reboot and your Mac will restart and boot normally. Only this time, Setup Assistant will launch. Download spotify playlists to usb.
Security Concerns
By now, you're probably wondering why should this be even possible, since someone may use this to gain access to a Mac. Indeed, re-running Setup Assistant would certainly allow for an unauthorised person to create a new account with administrative privileges and gain access to the Mac along with your data.
In terms of security, physical access trumps almost every method of preventing unauthorised access not involving encryption. While a little more complicated with the SSD technology Apple uses in their product lines, access to your data can easily be done simply by removing the Mac's storage device and connecting it to another.
This is where encryption methods such as Firmware Password and FileVault 2 are useful. With a Firmware Password set, it must be entered if the Mac is being booted either into Single-User Mode or to another boot volume. FileVault 2 takes this one step further by performing full disk encryption, preventing any form of access to your data unless authorised by entering your user account password - even if the drive is removed and attached to another Mac.

Patch pro evolution soccer 2013 download. If you own Intel-based Macs, you can run OS X and Windows on one machine. In fact, it’s been possible to run Windows on a Mac for some time — with agonizing limitations. Near-extinct Mac models were loaded with Virtual PC emulation software could do Windows, too, but the program was painfully slow. Even if you find an old copy of the software, it won’t work with any current Macs.
Boot Camp software from Apple shook up the computing public upon its apocalyptic arrival in April 2006. Boot Camp graduated from beta, or near-finished, status with the arrival of Leopard. Boot Camp Assistant software is stored in the Utilities folder inside the Applications folder.
Boot Camp itself is free. You have to supply your own single-disc or downloadable full-install version of Windows; an upgrade disc won’t cut it.
It’s also important to note that you can use a 64-bit version of Windows, Windows 7 (Home Premium, Professional, or Ultimate), Windows 8, or Windows 8.1. Consult Apple support to see which Mac models are compatible with which versions of Windows. In its current incarnation, Boot Camp isn’t compatible with 32-bit versions of Windows.
Other requirements follow:

If you don’t run into snags, the entire installation should take about an hour.
Windows 8 and Windows 8.1 are optimized for a touchscreen environment, though you can use it with a standard mouse and keyboard. For now, Macs don’t support touchscreen computing.
To install Windows 8 via Boot Camp, you still must have a legitimate Windows 8 license from Microsoft and a Win8 installation disc, assuming that you have an optical drive. If you don’t have an optical drive, you may be able to create a Windows installer from an ISO file downloaded from Microsoft on a USB flash drive that’s 8GB or larger.
Because snags are possible, back up all your important information on the Mac’s startup disk.
