Atheros Installer for 10.14 and 10.15 2.0

Disable SIP before running the installer.



Change Log:

• Added the Atheros Support for macOS Catalina.
• Added macOS detection for necessary file installation.
• Backing up the original IO80211Family.kext for macOS Catalina to desktop.

Known issues:

• No 5GHz network detection.
• Rebuilding system caches with SIP enable ends up with errors, so you need to disable SIP from recovery partition.
• After each major macOS Catalina update you may need to run the installer.
