KisMAC - Welcome
KisMAC will scan for networks passively on supported cards - including Apple's AirPort, and AirPort Extreme, and many third-party cards, and actively on any card supported by Mac OS X itself. Cracking of WEP and WPA keys, both by brute force, and exploiting flaws such as weak scheduling and badly generated keys is supported when a card capable of monitor mode is used, and packet reinjection can be done with a supported card (Prism2 and some Ralink cards). GPS mapping can be performed when an NMEA compatible GPS receiver is attached. Data can also be saved in pcap format and loaded into programs such as Wireshark. KisMAC Features KisMAC
How do I change my MAC address? Although physical MAC (Media Access Control) addresses are permanent by design, several mechanisms allow modification, or "spoofing", of the MAC address that is reported by the operating system. This can be useful for privacy reasons, for instance when connecting to a Wi-Fi hotspot, or to ensure interoperability. Some internet service providers bind their service to a specific MAC address; if the user then changes their network card or intends to install a router, the service won't work anymore. Changing the MAC address of the new interface will solve the problem. Similarly, some software licenses are bound to a specific MAC address. Changing the MAC address in this way is not permanent: after a reboot, it will revert to the MAC address physically stored in the card.
Set the primary display on a dual-screen Mac setup If you are running a dual-display setup, you can easily adjust the primary display monitor in Mac OS X. When would you want to do this? For example, if you have a MacBook Pro 13″ hooked up to a larger external display, and you want the external display with it’s higher resolution to become the primary display, and your MacBook Pro with it’s smaller resolution to become the secondary display. This is just a matter of settings adjustments and it only takes a minute to configure, though it’s not particularly obvious at first glance. Let’s walk through how to set the primary screens: You will obviously need an external display to use this feature.
A MAC address is a unique identifier assigned to your network card, and some networks implement MAC address filtering as a method of security. Spoofing a MAC address can be desired for multiple reasons, and it is very easy to spoof your MAC address in Mac OS X 10.4, 10.5, 10.6, and 10.7. For the purpose of this article, we are going to assume you want to spoof your Mac’s wireless MAC address. How to spoof your MAC address in Mac OS X
