How to Remotely Access Your Mac – Part 2

In the last article of this series “How to Remotely Access Your Mac – Part 1” I described how you can access your Desktop Mac from a MacBook when they are both on the same network. But what if you are at work, or in the neighborhood coffee shop or on vacation half way around the world?

There are ways to set up your Mac so that you can access it. The easiest way to set up remote access is through the use of “Back to My Mac”. This is approach uses software that every Mac has and iCloud. Both Macs must be using the same iCloud account. If either of the Macs are behind a firewall, it must be configured to allow the remote connection.

Rather than go into the details of how to set up and use this method, let me just summarize. A detailed configuration written up by Apple [See Reference 1 below] is available. Basically all you have to do is go into the iCloud Preferences pane on the target machine and select Back to My Mac. On the client Mac, open a finder window and use the sidebar under Shared to select the Mac you want a remote connection to.

I have not been able to test this method myself. More on that in a moment. From what I have read, this method has a spotty history of working. If you can set it up, you might want to try this as it is an all Apple solution, but read the warning paragraph below first!

WARNING – So why couldn’t I try this? Well, the router behind which the target Mac sets must have UPnP or NAT-PNP enabled. In my case, my home router supplied by AT&T Uverse will not allow either of those settings, and that is for good reason. Having UPnP turned on is a security risk. Most security experts agree with this sentiment, so even if your home router allows UPnP to be turned on, it is NOT a good idea to do so.

Podcast – Security Now


Podcasts – I have been listening to the Security Now podcast since it began. It has been published weekly now for over 10 years. The latests episode as of this writing is #626. While they began as short programs of under 30 minutes, they have rapidly grown to around two hours per episode.

The show is presented on the TWiT Network and features Leo Laporte and Steve Gibson. While, as the name implies, the focus is on computer security, they also will talk about Tech in general and Science Fiction from time to time. The more recent episodes cover the security news that has occurred over the past week (almost always something new). They sometimes address questions from their large international audience, with occasional deep-dives into an issue of computer technology or security.

The program is well done and I recommend it to anyone interested in computer security, or who simply uses a computer, tablet or smart phone.

Review of the Anker USB 3.0 to Gigabit Ethernet Adapter


Product Review – A few months ago my home suffered a lightening strike that. among other things, broke the ethernet port on my Mac Mini. While I have been able to use the built in IEEE 802.11 (Wi-Fi) connection, I prefer a hard wired network connection.

A few days ago I found the Anker USB 3.0 to Gigabit Ethernet Adapter on Amazon and thought it would be just the accessory to put my Mac Mini back on the wired network. I ordered it and it arrived yesterday. I was able to install it easily: connect a RJ-45 cable from my Ethernet switch, then just insert the adapter into a free USB port on my Mac Mini.

The new connection was immediately recognized by macOS and I was back to using the wired connection. While I have only been using if for just about 24 hours it has worked perfectly so far.


  • Easy to install
  • Low cost ($13.99 as I write this review)
  • USB 3.0 compatibility, backwards compatible with 2.0/1.1
  • Gigabit Ethernet support
  • Portable if needed
  • Compatible with macOS and Windows
  • Powered by the USB port



  • Does require committed use of a USB port



This is a product that I would recommend to anyone who needed to add a wired Ethernet connection to your Mac or PC. You could also use this to add a higher speed or second Ethernet connection to your computer.

Having Trouble with Wi-Fi on your iOS Device?


I noticed yesterday that my iPhone 5 was not connected to my home Wi-Fi network. I tried to simply select my home network and connect, but that didn’t work. That motivated me to look into iOS Wi-Fi issue more deeply.

From my investigation, iOS has been plagued with Wi-Fi connectivity issues for some time. From the many sources I reviewed, these are the recommended steps (more or less in this order):

  1. Make sure your Wi-Fi router is on and working – I verified this by using my iPad. Do not assume that your network is functioning verify it.
  2. Make sure that your phone is configured for the Wi-Fi network – on your iPhone
    1. go to Settings and make sure that Airplane Mode is off (switch is gray)
    2. go to Settings >> Wi-Fi. Make sure that Wi-Fi is enabled. (switch is green)
    3. go to Settings >> Wi-Fi. Make sure that your Wi-Fi network is the one selected
  3. Forget the current Wi-Fi Network and rejoin it – on your phone
    1. go to Settings >> WiFi
    2. tap on the network currently selected (right under the line with the Wi-Fi enable switch)
    3. then tap on the “Forget This Network” that appears at the top of the next screen
  4. Reboot your phone – Use the power button to shut down, then restart your phone. Repeat step #2 above
  5. Hard Reset your phone – A hard reset does more than rebooting. This clears saved items in memory and clears any caches and other things that are normally saved when you power off your phone.
  6. Reboot your Wi-Fi access point – power it off, then on after 15 seconds or so. Repeat step #2 above
  7. Disable Wi-Fi Networking Services – some sources claim this helps sometimes
    1. go to Settings >> Privacy >> Location Services
    2. disable “Wi-Fi Networking”
  8. Toggle Wi-Fi Assist – some sources say this may help (I recommend that you leave this feature turned off)
    1. go to Settings >> Cellular >> Wi-Fi Assist
    2. change the state of the slider, wait 15 seconds or so and change it back (i.e. ON-OFF-ON or OFF-ON-OFF as the case may be)
  9. Reset your phone’s Network settings – go to Settings >> General >> Reset >> Reset Network Settings (NOTE: This will remove all network settings and passwords)
    1. when prompted, enter your password
    2. confirm that you want to Reset Network Settings
  10. Try connecting to a different Wi-Fi network – Try to access a friend’s or a public Wi-Fi network. This will verify that it is nothing to do with your home Wi-fi network. Logically I would put this as #9, but it most likely requires that you go somewhere to get access to a different Wi-Fi access point, so I moved it lower on the list.
  11. Restore and Setup as new iPhone – restore your phone to the factory settings [1]. This will erase everything from your device. Make sure that you back up to iTunes or iCoud first.
  12. Seek professionally assistance – Time to make an appointment at the Apple Genius Bar, or your carrier.

Sadly, I have tried 1-10 and I have not had any success . . . yet. Later this week I will try #10 – a restore to factory settings. After that, I think it is a trip to the Apple Store. Unfortunately, I am thinking that my iPhone is on it’s last legs and it is time to replace it.
