I just installed v5.40 (IDE and IPE).  Got the IDE to work, but the IPE does not un-gray the Device and Tools buttons.  The Device and the tools selections are correct, but the Accept and Connect buttons are grayed out.  I am using the Microchip Curiosity 2.0 PIC MZ EF board with the Curiosity/Starter Kit Pk0B4 debugger interface.
 
This board and software worked with v5.35.  What's wrong?

Sanity check.
You ARE exiting the IDE before running the IPE?

Oh yes! Power cycled the board many times.  Nothing obvious (I hope).

Hi,
So, you confirm that with MPLAB X IDE  v5.40 you can debug and program your board ?
If so it means your curiosity board firmware has been updated and there is no reason why MPLAB X IPE would not connect to it as both IDE and IPE use the same DLL BUT.....it is mandatory to exit MPLAB X IDE before to launch MPLAB X IPE. Only one can actually work at anytime either (exclusive) or the other.

What is this answering?
Certainly not my question, which is the same as RISC's.

This is the question I was answering.
 
More tests (all are run on MacOS).  I restarted the Mac so there is no hidden residual IDE.  Started the IPE v5.40 and see the same thing (no green dot next to the device).  Exited IPE v5.40 and started IPE v5.35 without touching any of the hardware or connections.  The v5.35 worked perfectly.

Hi,
I'm not seeing this on Windows 10 but I can't comment for MacOS. 
Is your MacOS OS version listed in MPLAB X v5.40 as supported officially ?
If so you should probably go for an official support request

@BillP,
 
I have an observation but not a solution.
 
When I started using v5.40 with my PICKit4, the real deal not a PKOB4 started kit, I encountered some significant strangeness. What resolved it for me was to use the IPE menu: Tools->Hardware Tool Emergency Boot Firmware Recovery
 
This method reverts the Atmel controller in the PICKit4 to a USB CDC serial device and allows the Microchip firmware to be loaded like it's the first time.
 
This process will show you how to get the PICKit4, SNAP, ICD4 and PICKit4 OnBoard device programmers in this recovery mode.
 
I have done with using the Windows OS, but I want to be clear:
 
I do not know that this will solve your issues with the MAC OS, PKOB4 and IPE tool.
 
Having no MAC OS to try this on I do not know what will happen. The worst case is that you will need a Windows OS with MPLABX v5.40 installed to run it the way I know works. Best case, it fixes your problem. Being a pessimist I suspect this will not be helpful.
 
If you try this please let us know what happens.

This post is just for information in case others see the same problem.  This issue is not important to me.  MPLAB X IDE v5.40 works just fine to develop applications and download to the Curiosity board.  I rarely use the IPE and if I need it, I can use IPE v5.35.

Hi,
 
This post is old but i'd like to share what i did to make MPLAB IPE work (I was also able to debug and program using MPLAB X IDE but it was impossible using MPLAB X IPE): 
I went into MPLAB X IDE, i selected "use specified toolpack" in pickit 4 settings in "project properties".
I then changed the USB cable and the USB port, opened MPLAB X IPE and everything was finally working fine.
I went back to the former USB cable and the former USB port and it was still working...
