This post is made for test purposes and issues with Google indexing The "real" post is found  here  !! The use case was that we on our yacht have a security alarm which is using 2 G, service terminating during 2024 ?, so it was time to check for some other solution...........

In a former post I used a nice Python program to get the installers but as you know there are no Python installed in later Mac OS. The program used in this post is the fantastic Open Core Legacy Patcher . (No Python dependencies.) This patcher is made for supporting old Mac:s with new OS:s , which is not officially supported, but here we just use it for getting the USB installer.

Updated 2023-06-01 ! My old boat/travel WiFi router didn't behave so I was forced to look for a new one with these  must functions;     Built in SIM 4G/LTE capabilities      WAN failover      Powered with 12V DC      Bridge public WiFi:s, or my phone, to LAN I did a lot of Googling and ended up with Teletonika RUT 240 (TR)..... This post will cover a setup summary for the RUT 240 model, but it's useable for other Teltonika models too since they have a common firmware. Check these posts ! Teltonika router as security, burglar, alarm !                                 Bridged Teltonika router as source for router or mesh network

Updated 2023-05-04 ! This post focus on  Shelly 1 (S1), a really a nice automation device with great versatility, but much of the content is also valid for some of  Shellys other devices  using the gen1 API. Setup for the later version,  Shelly Plus 1 , is found here  !! S1 is a WiFi switch, 16 Amps, with dry contacts and t he function "without Internet" + that the S1 can use a 12V DC source makes it perfect for an "use case" in a  boat /mobile home. It's compatible with Alexa , Google  or HomeKit using HomeBridge  or as a "native" HomeKit device using  Mongoose firmware (Flashed via a standard WEB browser !)

Updated 2023-05-03 ! In a  former post I made a writing about Shelly 1 (S1) and this post will handle about the successor Shelly PLUS 1 (SP1)  but much of the content is also valid for some of  Shellys other devices  which uses the same software/API. To keep it simple, SP1 is a WiFi switch, 16 Amps, with dry contacts but compared to the S1 the hardware and the software is updated.  The function "without Internet" + that the SP1 can use a 12V DC source makes it perfect for an "use case" i n a boat/mobile home .

Updated 2023-05-01 ! I really recommend flashing, via WEB-browser, the device with Mongoose software to avoid Homebridge.   HomeBridge is used for this setup and to make it appear in the Apple Home app. The main advantage with the Shelly devices are that they are WiFi enabled and therefore You don't have to use a hub, this compared to z-way/zigbee and some other solutions.  First install Shelly1 (S1).

Updated 2023-06-11 ! The use case is that I had an old iMac, max OS is High Sierra, that crashed and it didn't work with an Internet or Time Machine restore. The other MAC:s I have are running Catalina or Big Sur and if you try to download and older OS , via app-store, you just get an error saying that the running OS don't accept the download of an old OS. The universal way to create an USB installer seems to be using the command " createinstallmedia ", requires OS X 10.7 Lion or later, but you need the respective OS install app ! A new, better ??, without Python dependences is found here .

In former posts, Big Sur (11.7) and Monterey (12.7),   I went through how to update an old MacBook Air 4.2, (mid 2011, SSD, 4 Gb memory) which has a Non-Metal GPU. In this post I will update a MacBook Air 6.2 with SSD, Mid 2013,  to Ventura(13.5) with the same patcher  but the latest version 6.2 !!  This is despite that  max OS  for this Mac is  Big Sur Awesome !! ! Supported models are found here .

Since I'm not a programmer, and probably never will be 😉, I really like Node-Red(NR). NR is also a nice way trying to learn some JavaScript via the function nodes. I also appreciate hardware, MCU s, like ESP32 and Raspberry Pi Pico but find it a little hard to code in MicroPython or C++. Somewhere ?? on the WEB i found some applications that can export NR json code to C++ and run it on several MCUs. As you understand I had to check it out...
