for some reason none of the Arduino boards I own show up when connected on version 2.3.2 of the programming software. What makes it stranger is that the boards show up and work perfectly fine on older versions of the software. this is the case on both my windows and MacBook computers. is there something wrong with my boards or software I'm using?
Just to make sure.
You're running both IDE 1.x and IDE 2.x on the same system(s)? IDE 1.x recognises them and IDE 2.x does not?
Which boards do you have problems with? Please name them because "all of them" does not mean much to us 
I have an Arduino uno, a few nano boards, a teensy 4.0 and an Adafruit itsy bitsy. when I plug these boards in using the new software they don't show up as plugged in, but when I use the older version of the software they work.
Which computer are you using now? I ask because, although the information that the problem occurs on both computers is very relevant, for the next phase in the troubleshooting process I think it will be best to consistently use a single computer in order to avoid confusion. Knowing which operating system that will be used will allow us to provide you with the appropriate instructions.
So that I can be sure I understand, please provide a detailed description of what you mean by "don't show up". Are you looking for them to "show up" somewhere in the Arduino IDE user interface? If so, where exactly are you looking?
When I plug the boards into the old software, they show up in the serial port section. when I try to use the new software, the serial port tab shows nothing. I am able to use my boards on either computer as long as I use the old software.
Please answer the first question I asked in my previous reply:
I'm not sure I understood correctly what you mean by "serial port section". Please add a forum reply here that provides a more detailed description to help us to understand it.
If you don't know how to describe it using words, you can make a screenshot and attach that to a reply here.
I'm using my windows computer, but I got it working on my mac too. under the tools tab on the software where you choose the type of board and the port, I'm supposed to see the connected boards, but in the new software the port selection is empty.
Have you tried uninstalling the newer software, then reinstall it to a different directory?
Windows can be fickle at times, not cleaning up registry entries properly and could leave a corrupted entry in the register, which gets picked up when installing to the same path.
As an aside, look out for background programs that run. I have had trouble with a VPN stopping Arduino 2.x not working properly, whenever it is switched on. Just make sure you kill all background tasks as a test to see if anything is interfering with the program.
