I hope someone is able to help me, I have a MacBook Air and I can’t get it to recognize my Arduino when I try to program it.
Welcome @hoytfreak
I'm sorry but I'm a W7 guy so I can't help you about the Mac, I hope some others here use that platform.

There are Mac users on this forum, but as ZeFerBy, I'm a Windows user, with a sprinkling Linux, so for Apple help, I'm of no use.

I am a Mac user, your description is a bit ambiguous and vague!
Which Arduino are you trying to program?
Does the IDE startup OK?
When you try to upload the program, does Tools/Board show the right Arduino?
If the above is true, what available ports does the Tool/Port show?
I have an uno and the ide opens fine but it won’t communicate with the Arduino
My guess is that you have a USB problem. If you are using a new Arduino clone then the USB driver that comes with the Arduino IDE won't work and you need to install the USB driver from the zip file below.
The reason is that most clone manufacturers have changed from the FTDI USB to serial chip to the CH340g chip. This driver is imperative if you try to program Nanos.
You might have to run the install a couple of times before it is recognised. If I remember correctly, I had to do that when I tried to install the driver for the first time.
