FIRMWARE UPDATE FOR MONTEREY?
I have been told a firmware update is needed to install Monterey. When attempting to install Monterey, I get this error alert: "required firmware update could not be installed. Compatible internal storage is required in order to update".
My Mac: MacBook Pro (Retina, 15-inch, Mid 2015)
Apparently the firmware update must installed PRIOR to installing Monterey.
