Tried the LSMinimumSystemVersion key and no go, same message. I already have 1.8.5 and TL 1.44 running on it, was just curious why your not recommending this code signed version for...

FYI
I was a little surprised (and thankful) that I was able to modify the boards.txt file in the app and gatekeeper didn't seem to mind. I even transferred the modified app to a mac mini running...

Installed the 1.49-beta1 from msg #43 and was a little confused.

Sorry, missed this thread and just installed the 1.49 beta #1 yesterday.
For any help I might provide should I install the version at #43 above or wait for 1.49 beta#2 or ? Will betas be code...

@TheWell
There is a wiring error in chipaudette's picture you used.

I can report that today after doing nothing more than having the Mac sleep overnight, not turned off, Catalina, Arduino 1.8.10, and Teensduino 1.48 seem to be happy again. Perhaps all the...

Just made the mistake of updating Mac to 10.15. I looked around in the forum first but missed this thread. dang!

The @Theremingenieur and @Balum methods don't work for me. I can't get the...

On Mac 10.14.6, Arduino 1.8.10, T1.48b2 the monitor window looks reasonably disabled and allows copying when unplugged, Yaa!! Have to admit that feels kind of weird copying from a dead window, but...

works for me on a Mac also.

thanks

Commenting out the differences in startup.c between 1.8.9 and 1.8.10 seems to fix the problem.

No idea what it's meant to do or any other effects.

@Kurt,
Thanks, thought I was being ignored. But wait !! Another clue !!

DemoSauce.ino runs on 1.8.10 if I set optimize to "Smallest Code" !

This also makes the rest of my programs work that...

I have narrowed down a T4 crash with Arduino1.8.10 TD1.48b1 a little more. After re-installing Arduino1.8.10 and TD1.48b1 the issues I was having in many programs went away (as should be expected if...

At message #47 I said 1.8.9 works with 1.48b1. That not quit a correct statement. The 1.8.9 used 1.47 for it's initial TD installation. It works correctly with the 1.48b1 TD not necessarily the...

Here's the Teensy verbose output showing the port closing at the very end:(edit, or I guess never opening)

Just re-downloaded and re-installed both. Now Arduino1.8.10 shows a more reasonable 855MB and the library callouts look better

/Applications/Arduino.app/Contents/Java/arduino-builder -dump-prefs...

Yes, I installed all the libraries. However, looking at the Arduino file size its only 599MB where 1.8.9 is 785.6MB.

Did you try to compile myT4WavDisplay.ino or some other sketch?

and here's the output from above in same setup which crashes the T4:

Aside from the monitor speed stuff, on Mac 10.14.6 I've had several issues with programs compiling and or running differently between Arduino 1.8.10-TD1.48B1 and 1.8.9-TD1.47, on both T4 and T3.6. I...

That 'Serial' means serial over USB I think. You still use the serial port. Perhaps you need to press the button on the Teensy to get it to show up in the ports for the 1st time per the...

That is what's available now with Teensy 4.0.

I don't understand how the CS pins work on the T4. On T3 there was one SPI bus but many CS pins to choose from for each peripheral.

On T4 there are three SPI buses but only one CS pin for each.
