I dropped TTMSFMXNativeNSTextView control to a main TForm and aligned it to the entire client area.
All is working fine, but Cmd+A, C, V are not working, this is unlike the default NSTextView behavior.
We have investigated this here and confirm this is an issue due to an incorrect implementation in the FireMonkey framework. We will look for a workaround for this issue.
