Important note for MacOS El Capitan & MacOS Sierra

Due to changes in the latest OSX operating systems from Apple, Mac users whose Macs are running MacOS El Capitan or MacOS Sierra must follow the steps below before installing KnowIT otherwise the KnowIT installer will fail and KnowIT cannot be installed.

This only applies to MacOS El Capitan and MacOS Sierra  If the Mac is running MacOS Yosemite or earlier then these steps are not needed. 

This is split in to two parts, for Macs running with one hard drive partition and for Macs with more than one hard drive partition.

FOR MACS WITH ONE PARTITION

  • Boot your Mac in to recovery mode

To do this, turn off your Mac completely and then hold down Command & R whilst the Mac boots up. 

Instead of booting in to MacOS it will boot in to the recovery environment which looks like this.

  • Open up Terminal: From the Utilities menu, click Terminal.

 

When the Terminal window appears type in the following:

csrutil disable

Press Enter.

A message will appear to confirm the command was processed successfully.

  • Restart the Mac and install KnowIT

Click the Apple icon in the top left-hand corner and then click Restart.

Once the Mac restarts log back in to your KnowIT online portal and follow the steps to install KnowIT on to the Mac again and the installation should now complete successfully.

 

FOR MACS WITH MORE THAN ONE OPERATING SYSTEM

  • Boot your Mac in to recovery mode

Make sure the Mac is turned off completely. 

Turn it back on and hold down Alt whilst the system boots up. 

Select the OS X 10.11 recovery partition from the list.

This will boot the Mac in to the recovery environment.

  • Open up Terminal

From the Utilities menu, click Terminal.

When the Terminal window appears type in the following:

csrutil disable

Press Enter.

A message will appear to confirm the command was processed successfully.

  • Restart the Mac and install KnowIT
