If you own a Bearifi BearExtender Turbo AC1200 USB adapter, or one of our legacy Mac products, and you are trying to install on Mac OS 10.11 or newer, you may find the install does not work because SIP protection is enabled on your Mac

SIP protection defined by Apple as "technology in OS X El Capitan and later that's designed to help prevent potentially malicious software from modifying protected files and folders."

It locks down the system extensions folder which makes it so driver applications like ours cannot write to that folder unless you disable SIP protection.

For any concern that disabling it makes your Mac vulnerable, it makes it as safe as it was in Mac OS 10.10 and earlier. You are essentially just allowing applications to write to your system folders again. As always, never run any application from a source you don't trust, and always use antivirus software.

How to disable SIP protection

To use any of our Mac installers on most 10.11 and newer Macs, you will need to first disable SIP protection before installing the software. If you already installed the software, uninstall it. Then take these steps to disable SIP protection:

1. Click the Apple menu.
2. Select Restart...
3. Hold down Command key and R key to boot
into the Recovery System.
4. Click the Utilities menu and select Terminal.
5. Type csrutil disable and press return.
6. Close the Terminal app.
7. Click the Apple menu and select Restart...

Now install the software desired and you should be able to use your product.
