Re: [Qemu-devel] Mac keyboard not supported

[Fabrice Bellard <fabrice@bellard.org>]

For the problem of the Mac keyboard, I think SDL should be fixed first 
to return correct SDL keysyms.

An interesting patch was submitted some time ago to use the scan codes 
directly, as we do on PCs (scan codes do not depend on the keyboard key 
mapping). If it is reported to work on most Macs, it should be the 
default because it avoids the problem of translating keysyms to scan codes.
