  2. On a mac instead of doing ifconfig you can run networksetup like below to show all your interfaces and the assigned Mac-Address dennis$ networksetup -listallhardwareports Hardware Port: Wi-Fi Device: en0 Ethernet Address: 78:4f:43:8d:54:d8 Hardware Port: Bluetooth PAN Device: en6 Ethernet Address: 78:4f:43:90:0b:f0 Hardware Port: Thunderbolt 1 Device: en1 Ethernet Address: 82:dc:af:e0:cc:01 Hardware Port: Thunderbolt 2 Device: en2 Ethernet Address: 82:dc:af:e0:cc:00 Hardware Port: Thunderbolt 3 Device: en3 Ethernet Address: 82:dc:af:e0:cc:05 Hardware Port: Thunderbolt 4 Device: en4 E
  3. Tried to capture packets for a NAT address ( is NAT Pool) for my VMWare Fusion session. When on my mac I ran the following command I'm getting some weird error messages. dennis$ sudo tcpdump -i any -v network tcpdump: data link type PKTAP tcpdump: listening on any, link-type PKTAP (Apple DLT_PKTAP), capture size 262144 bytes pktap_filter_packet: pcap_add_if_info(en9, 1) failed: pcap_if_info_set_add: pcap_compile_nopcap() failed pktap_filter_packet: pcap_add_if_info(bridge100, 1) failed: pcap_if_info_set_add: pcap_compile_nopcap() failed pktap_filter_packet: p
  4. Thanks for the tip. Good article
  5. My Mac was infected by an adware called anysearchmanager, but Malwarebytes can't help. I removed it from this article: https://www.securemacos.com/remove-search-anysearchmanager-com-virus-from-mac-os/
  6. So how to locate or update or refresh or rescan iTunes library? Easy-Fast way (not always successful) First quit iTunes app. Re-launch iTunes app while holding down the Option key. Select “choose library.” Go the iTunes folder and choose it. Another method that always works for me (just takes forever) Launch iTunes app on your computer Navigate to File -> Add to library Select the location of your iTunes library (ex: iTunes folder) iTunes app will relocate or refresh all meta data and files you already have to library. Don’t worry i
  7. This is what I did... On the Watch: Go to General --> Settings --> Reset --> Erase All Content and Settings Let the Watch reset back to basically the state that it came in when it first arrived. Pair the Watch again to the iPhone: Open the iPhone app and pair it to my Apple Watch. Restored my Watch from the back-up. Put my Watch on the charger. Opened the Apple Watch app and applied the update from my iPhone.
  8. Anytime I try and upgrade my iWatch it says it can't because there is no internet connection. I verified I have internet connection. I also went to airplane mode and just had WiFi and Bluetooth, validated my internet (WiFi) worked and still won't upgrade. Any ideas?
  9. Very True yet the number of viruses, adware and spyware for other operating systems is typically much higher than the Linux based Mac OS. The facts are: There is no anti-malware software that can detect 100% of the malware out there. There is no anti-malware that can detect everything targeting the Mac. The very best way to prevent the most attacks is for you as the user to be aware that the most successful malware attacks rely on very sophisticated social engineering techniques preying on human avarice, ****, and fear. Internet popups saying the FBI, NSA, Microso
  10. Unfortunately everything changes. Today Mac OS is not so secure. This article describes Safe Finder virus from Mac http://macsecurity.net/view/124/
  11. You can change the system preferences for JoinMode and JoinModeFallback to be the following: JoinMode (String) Automatic Preferred Ranked Recent Strongest JoinModeFallback (String) Prompt JoinOpen KeepLooking DoNothing Do this using the airport command: /System/Library/PrivateFrameworks/Apple80211.framework/Versions/A/Resources/airport Run the command to see the options, up the top you'll see a section on how to sec preferences. $ /System/Library/PrivateFrameworks/Apple80211.framework/Versions/
  12. Check out this link from Cisco http://www.cisco.com/c/en/us/td/docs/wireless/controller/technotes/8-2/b_Enterprise_Best_Practices_for_Apple_Devices_on_Cisco_Wireless_LAN.pdf Navigate to WLANs > Security tab of the WLAN and check both FT and non-FT authentication. Example 802.1X and FT 802.1X, or PSK and FT-PSK. Non-802.11r clients which have the updated wireless LAN drivers for '802.11r-compatibility' can now join this 802.11r-mixed-mode WLAN. It is important to note that laptop clients with newer wireless LAN chipsets and updated chipset drivers with 11
  13. For system administrators, OS X roaming helps your Mac stay connected as it moves between different places within your office wireless network. Trigger threshold The trigger threshold is the minimum signal level a client requires to maintain the current connection. OS X clients monitor and maintain the current BSSID’s connection until the RSSI crosses the -75 dBm threshold. Once that threshold is crossed, OS X initiates a scan to find roam candidate BSSIDs for the current ESSID. Consider this threshold in view of the signal overlap between your wireless cells. For example,
  14. iOS Roaming Trigger threshold The trigger threshold is the minimum signal level a client requires to maintain the current connection. iOS clients monitor and maintain the current BSSID’s connection until the RSSI crosses the -70 dBm threshold. Once crossed, iOS initiates a scan to find roam candidate BSSIDs for the current ESSID. This information is important to consider when designing wireless cells and their expected signal overlap. For example, if 5 GHz cells are designed with a -67 dBm overlap: iOS uses -70 dBm as the trigger and will therefore remain connected t
  15. Sometimes its helpful to know what ports on your Mac are in LISTENING status. So here are a few commands that I found helpful in my quest to find what ports are open. $ netstat -atp tcp | grep -i "listen" tcp4 0 0 *.irdmi *.* LISTEN tcp4 0 0 localhost.49155 *.* LISTEN tcp4 0 0 localhost.49154 *.* LISTEN tcp4 0 0 localhost.49153 *.* LISTEN tcp4 0 0 localhost.49152 *.* LISTEN tcp4 0 0
  16. Download your ISO first Open the Terminal (in /Applications/Utilities/ or query Terminal in Spotlight) Convert the .iso file to .img using the convert option of hdiutil hdiutil convert -format UDRW -o /Users/dennis/Downloads/ubuntu-14.04.3-desktop-i386.img /Users/dennis/Downloads/ubuntu-14.04.3-desktop-i386.iso Reading Master Boot Record (MBR : 0)… Reading Ubuntu 14.04.3 LTS i386 (Apple_ISO : 1)… Reading (Windows_NTFS_Hidden : 2)… ...............................................................................................................................................
  17. With the introduction to El Capitan they removed the disc burning ability from the Disk Utility which is where most of us went to burn an image. So from El Capitan (10.11) and newer (or until they change it again) the below will be the way to do it. But no worries, they didn't take it completely away, more of relocated it. Open Finder and click once to highlight the image you want to burn. Then click Burn Disk Image "blah blah blah" to Disc... the Burning process will begin.. as long as you have your blank media in the drive.

  18. There comes a time that the DNS server(s) do not have the name to address resolution you need so just add it to your local hosts file. Mac OS X 10.2 or later Edit the /private/etc/hosts file. For more information on how to use the hosts file, open Terminal and type: man hosts Note: Editing this file requires root privileges. I suggest typing while in Terminal sudo nano /private/etc/hosts It may be a good idea to flush the DNS Cache that is running by then typing the following after you save the hosts file dscacheutil -flushcache
  19. Switching operating systems is a scary and can be exciting adventure. It can also be a major pain in the butt. I am not author of any book but hope I can help fill in some blanks. If you want a recommendation on a book, for beginners I strongly recommend a book called Teach Yourself VISUALLY Mac OS X Leopard It has proven itself to people of all ages on getting up and going with there move from Windows to Mac. Here are some basic things you may or may not know. Open Applications... In Windows you click the Start button - Click on Programs - Select Your Application In Mac OS X you click
  20. I am curious as to what I should do when I can not click on FInder (it just makes a sound everything I click on it like something is in the background waiting for me to answer it but I can't seem to find anything). I can not open a new window and I'm not able to click on the apple to do a restart. Someone said to open terminal and type something like: sudo -h shutdown now but i can't get to Terminal. You could click on spotlight and type Terminal and it will find it for you at which time you could just double-click on. As far as shutting down or restarting your system you could do either wi
  21. One way to store or group files on a Mac is to create a Disk Image. A Disk Image is a file which has the properties of a separate hard drive or CD. It has a size limit and options for encryption to keep your files safe and secure. This how-to will work with Mac OS X. Steps Create a New Folder and place the files you would like in your disk image into this new folder. Right click (or CTRL-Click) the folder and select "Get Info" and note the size of it's contents. Open Disk Utility (Applications > Utilities > Disk Utility) Click the "New Image" icon to create a new dis
  22. Your bad kitty will run faster and smoother after it sheds a few gigabytes. A slimmer cat is a faster cat, and we'll bet dimes to DIMMs that you can shed several gigabytes from your Mac's hard drive without missing them. If you installed the default Mac OS10.4, for example, you've got 1GB of foreign language translation support, 2.1GB of printer drivers, and 9.9GB of bundled software. Once you've removed the biggest offenders post facto by following the steps below, take an hour to browse your hard drive for such junk as sample or stock images in Photoshop and sample songs in GarageBand (they
  23. Tweak processor priorities and RAM usage where available Mac OS X is a masterfully multithreaded system with the ability to run and manage hundreds of tasks simultaneously, including tasks that you've initiated (a Final Cut Pro render, a Photoshop filter, a spell-check in Word -- anything) as well as oodles of background daemons, enless Spotlight indexing, and other noise. It's your Mac, so you get to decide which apps get processor priority and when -- it's known as niceness in the Unix world. Make iMovie nicer as it chews on your epic film while you write your acceptance speech in Word, or
  24. The Mac is rightfully revered for the beauty, power, and simplicity of its graphical user interface. Indeed, it was the release of the first Macintosh that brough the concept of pointing and clicking to the average computer user. But in addition to the point-and-click ease of the OS X Finder, your Mac sports on of the most powerful command-line interfaces on the planet: the Terminal. Mac OS X comes with hunderds of Unix programs - and you can get them all through the Terminal. As much as we love the ease of the GUI, the power of the Terminal is hard to beat. It allows you to do many things fas
  25. nmap is the key... If you do not have nmap installed, then I suggest installing it. The best way to get this installed is using a program called fink. Note: You'll need to enable root user for nmap to work and know root password Once installed, open a terminal window and type fink install nmap (you'll have to type in your password just like you do when you install any program) Now that nmap is installed, run the following command nmap -sP -T Insane You should get an output like: You can also run Check out the GUI version of nmap for your Mac called Zenmap
