new HD on iMAc

[Stari Karp]

Hi!

I am sorry if FreeBSD Questions is not correct for my question but:

I have installed FreeBSD (now is 11-RELEASE) on iMac 11,1 where is also
OS X on but I do not using it years. Now I have a problem with hard
drive and I decided to change my HD with new SSD drive(I didn't buy
yet).
Is it possible to installed just FreeBSD on the computer, please? Now I
have dual boot and I use rEFit.
Thank you very much.
