Trying to record on my Mac with not much success.

Have followed Pear recommendations on his post on the subject. but I end up with "Demo xxxx" not found.

I have however been able to Record Screen on quicktime, not sure if that extension is OK to share eventually.

this has helped quite a few people mate
