How to Force iMac to Boot EFI

Shut down your iMac from the Apple menu. If you are trying to reboot into a special mode because your iMac is locked up, shut down the computer by holding the power key for five seconds.
Press the power key briefly while holding down the Option key. This provides a list of available disks with bootable Mac systems. Click on an alternative startup disk to boot your Mac from that drive, such as an optical disc or an external drive.
Repeat Step 1 if this does not produce the desired result.
Hold down 'S' and press the power key to launch into single-user or 'safe' mode. This provides you with a Unix prompt and instructions you can use to repair your boot volumes. These commands perform similar repairs to what can be done within the Disk Utility application, but this process will allow you to repair an iMac that cannot be booted.

How to Reimage a Macintosh Computer (6 Steps)

Attach an external hard drive to your Macintosh that has at least as much storage capacity as the space used on the drive you are imaging. You can skip this step if you already have a second drive with enough free space.
Launch the Disk Utility application from the Applications/Utilities folder.
Select the drive you wish to image by name in the list on the left-hand side of the Disk Utility window. This list will also include drives by their serial number. You should usually ignore these in favor of the named drives; however, select the drive by serial number if you want to create a single image of a drive with two or more partitions.
Choose 'File' > 'New' > 'New Disk Image from...', which will display the name of the drive you have selected.
Select the external drive in the Save dialog. If you wish, select a compression format and encryption method. Compression will create a much smaller disk image which still contains all the information on your original drive. Encryption will require a password before the disk image can be opened; if you lose this password, you will not be able to access the contents of the disk image.
Click 'Save' to create the disk image. Disk imaging can take a long time, especially if you are creating a compressed or encrypted disk image. You can continue to use your Macintosh during this time, but it will run more slowly due to the disk access required by the imaging.

How to Drain a MacBook Battery

Unplug the power cable from your MacBook and run the computer from the battery. Plugging in the cable will recharge the battery, so avoid doing this until you have fully drained the battery.
Click the 'Apple' button on your MacBook's desktop and click 'System Preferences.' Click 'Energy Saver.' Select 'Battery' from the 'Settings for' drop-down list. Select 'Better Performance' from the 'Optimization' drop-down list. This will disable many of the MacBook's battery-saving settings.

How to Find a Macbook's Manufacture Date (4 Steps)

Click on the 'Apple' icon located on the desktop, in the upper left hand corner of your MacBook's Finder window.
Scroll down to 'About This Mac,' then click on the 'More Info' button at the bottom of the window.
Note the 'Hardware Overview' pane on the right side of the window. Locate the 'Serial Number (system):' toward the bottom of the list. Locate the serial number for your Macbook in the 'Hardware Overview' window that opens. The serial number is composed of characters and letters, and contains the manufacture date.
Note that the first two characters in the serial number signify the location where your computer was manufactured. Examine the third character in the string, which is a single digit. This is the year your MacBook was manufactured. For instance, if the numeral is '8,' your computer was made in 2008; the numeral '0' would signify that the manufacture date is 2010, since the MacBook was not released in the year 2000. Now look at the fourth and fifth characters which signify the week that the MacBook was manufactured. The digits '12' for instance, would mean that the notebook was made in the 12th week of the year, which is the third week in March.
