Check before you upgrade to Mac OS 10.15 "Catalina"

In a few weeks Apple will release a new version of Mac OS 10.15 "Catalina" that will only run 64-bit software. The current Mac OS 10.14 (Mojave) will be the last version capable of running 32-bit applications.

Before you upgrade to Catalina I recommend to first veryfy wat app's will stop working after you install Catalina. Rolling back to the previous installed version of the Mac OS will be a very hard and costly to reverse.

The easiest way to verify the compatibily of your current setup is to install the free Go64 app from St. Clair Software. The app Go64 identifies the apps on your Mac that are still 32-bit so you can plan to update or replace them in the near future.

To completely remove redundant software from your Mac I recommend CleanMyMac. This is a great application to easily uninstall any software you want to remove from your Mac including all the hidden files that clutter our system. It is also an excellent maintenance tool that will help your Mac runninig smooth including general malware removal.

Cleanup your iPhone / iPad WiFi

Many people use Wi-Fi to connect to the internet when traveling, sometimes it doesn't want to work correctly.

Remove the unwanted Wi-Fi network by opening Wi-Fi in the Settings menu. Moreover, then tap the “I” symbol to the right of the network and choose “Forget This Network*. To avoid a constant disruption to connect to a Wi-Fi network, you happen to pass by. You should disable the popup message to join a Wi-Fi network by turning off “Ask to Join Networks.”

Sometimes a Wi-Fi connection needs a bit of help to make it work. Return to Wi-Fi in the Settings menu, tap the “I” and select “Renew Lease.” Besides, you can manually enter a DNS server address. DNS is responsible for directing your web browser to the IP address of the website you want to visit. Some DNS servers are better than others. It is worthwhile to change the DNS server address by tapping the “Configure DNS” section and change from Automatic to Manual. Remove any existing t DNS servers and search domains. Add a server electing the green “+” sign and use one or more of the following suggestions:

  • Google DNS

  • Google DNS

  • IBM Quad Nine fast & private

  • Cloudflare one of the leading web hosting service and is fast & private

Changing the DNS servers also helps to prevent the network operator of spying on your web browsing or redirect you to websites they want you to go. Better yet you can encrypt the DNS traffic with the app.

*Ultimately you can nuke all Wi-Fi and BlueTooth setting in: Settings > General > Reset > "Reset Network Settings.

Never trust a strangers network, whether its a hotel, airport, coffee shop, or Air B&B. There is a chance that someone else on the network will see every website you visit and intercept the passwords you enter or might try to break into your computer.

The best solution is to use a trusted VPN service. This application will rout all your data through an encrypted tunnel to another location on the internet and will put many barriers in place to protect your location and privacy. Be careful about choosing a VPN provider since they can see all your traffic. I did the research and found that Nord VPN is one of the best out there. Currently they have a -75% Offer!

Apple Card

Sometimes you have to use a physical card rather than the Wallet app on your iPhone or Apple Watch, and you need to use a plastic card or even worse hand over to a stranger who takes it to the back of the restaurant.


No numbers

You cant steal what you cant see.

When you activate the Apple Card on your iPhone, you can order a Titanium card (free) that you must activate with the very secure App on your iPhone. One of the first things you will notice on the Apple Card is that there is no other information other than your name. No numbers, expiration date or CVV code.

It's hard to steal a credit card number when you can't see it. The best part is that if the card is compromised, you won't' have to wait for a new card. Just the chat feature in the Wallet App and they will assign a new number to the card. And If you ever lose it, you can freeze it and order a new card right in the Wallet app.

Card numbers

If you can see the card info by selecting the card in the Wallet app on your iPhone and tap the "..." in the upper right corner and then select "Card Information". I used this information for online purchases and subscriptions that don't' support Apple Pay (yet).


Apple firmly believes in your right to privacy. Therefor Apple created a unique architecture for Apple Card that generates things like your transaction history and spending summaries right in the Wallet app on your iPhone. As we expect from Apple, the user interface is straightforward to follow and very informative.


Goldman Sachs will use your data to operate Apple Card. However, they will never share or sell your data to third parties for marketing or advertising.

Fun feature

The virtual Apple Card in the Wallet App on your iPhone will display various colors referencing to the kind of spending you did with this card.

Interesting article in today’s Washington Post, comparing a typical credit card (in this case the Chase Amazon Visa card, which until the Apple Card was my primary card for most purchases) to the Apple card.

It drives home the privacy aspect of the A.C. that makes it a compelling option.

"Despite a federal privacy law covering cards, I found six types of businesses could mine and share elements of my purchase, multiplied untold times by other companies they might have passed it to. Credit cards are a spy in your wallet — and it’s time we add privacy, alongside rewards and rates, to how we evaluate them… When I used my Visa, Chase’s privacy statement reserves the right to share my data for seven different kinds of reasons. The most appalling category is: “For nonaffiliates to market to you.” Who are “nonaffiliates?” Whoever the bank darned well wants. The term just means a company not owned by Chase. Chase would not tell me the specific data it shared from my card or the companies it shared it with… This is where the Apple Card is different. In the Goldman Sachs privacy statement, its answers to most kinds of sharing is “no.” Goldman still shares information with credit agencies about whether you pay your bills. But it says it doesn’t feed transactions to marketers or a sister company that mines card data."

EMP Proof network wiring

EMP proof network

While remodeling our new home, I took the opportunity to install network cables throughout the entire house, outside office and backyard. I installed multiple Cat6A SSTP/SFTP shielded network wires to every room in the house plus some other locations for security camera's and WiFi access points. Why still use old fashioned copper wiring?
