Oh, so this is an mac intel issue then.

I'm gonna make the suggestion do just remove support for Intel Macs for 
RTEMS 6.0.

I mean, what is the number of developpers who:

1) Will release a product based on RTEMS 6 (out in 2024 hopefully)
2) Have enough money to buy an Intel MacBook
3) Do not have enough money to upgrade 4 years later, especially with 
the 3x compile speed improvements the M1/2/3 brings?

My guess is zero. And there is always the possiblity to use a free 
Ubuntu MV on these obsolete macs.

I know the senior RTEMS developpers are very very busy, so I (selfishly) 
would prefer if they use their time for something more productive :)

Here at Precidata for example, we've put our product developpement with 
RTEMS on hold for the past 5 months, because of bug #4923 (STM32h7 FPU 
corrupted on return from IRQ).

So may I humbly suggest to forget obsolete developpement platforms and 
focus energy on new targets?

Thanks for your answers and all your work.

Cedric
