LEGO officially stopped supporting NXT in 2015, however, as of 2019, the original NXT programming software is still available on the official LEGO MINDSTORMS web page.
The original NXT programming software and EV3 desktop programming software are both 32-bit, so cannot run on macOS 10.15.
The new EV3 programming software based on Scratch does not work ...
LEGO Mindstorms all use flash storage which does have a limited number of write cycles, so the answer is technically yes in some capacity, but it's probably not something you need to worry about.
A LEGO Mindstorms NXT 2.0 uses a Atmel AT91SAM7S256 microcontroller. This board has 256 KB flash memory, which is roughly the size of the latest firmware image.
The NXT is no longer for sale by Lego, and I don't think they offer technical support for the NXT platform anymore. However, the EV3 software does support NXT. If you can't connect the software to the brick, it might be a driver issue. You can download the official NXT "Fantom" driver from the downloads page of the Mindstorms website - just scroll down until ...
I've found a very old NXTasy thread that answers this question definitively.
Flemming Bundgaard, from LEGO, ran two or three test-to-failure runs with my NXTTools utility repeatedly setting the brick into firmware download mode and downloading the standard NXT firmware to the brick. In each of his tests the brick failed, if I recall correctly, after ~...
If you want two things to run at the same time place the first just in front of but not touching the start block and the other just below the first. Click on the joiners (grey ovals on the end where blocks join) and press wire from here and tap on the first code. Do the same with the second.
This isn't exactly sending direct commands to your robot, but LEGO Education recently released a python stack for the EV3 brick.
I haven't tried it; but as I understand it, it's an alternative firmware which should allow you to have python scripts running natively on your EV3 brick, allowing for full autonomous robots programmed in python.
I’ve had a quick look through the MindSqualls code and it looks like you can. I cannot test this however as I don’t have two kits.
Note: I believe it is preferred to NxtBrick class rather than McNxtBrick class as the latter is for a special program used for precise control over the NXT motors.
Veering off a little bit is normal. Can it be reduced? Yes. There are several possibilities to consider, one of which is the programming. Put a pin in the hub of each wheel to serve as a marker, spin the wheels so the in the same position. Write a program to go straight for 20 revolutions. Hold the robot in the air, run the program, and examine the ...
According to the dexter website, there is sample robotC code which means, yes you can use the Dexter WIFI sensor with robotC. Maybe there are robotC libraries for it in the download section on that website.
This forum thread also loosley states that you can use the Dexter WIFI sensor with robotC
Hope this helped.
