I have recently purchased my first Apple mac. an imac with OS X 10.7 Lion installed - which includes iMovie11. I am considering purchasing a Panasonic HDC HS900 which handles AVCHD to a resolution of 1080/60p. I have read several posts on various Forums that indicate problems with this resolution being accepted by the OSX10.7 operating program. Although some very loyal Mac users took exception to any criticism whatsoever, and denied any incompatibility. Grateful for an unbiased statement regarding OSX10.7 and 1080/60p editing, before I commit to a purchase.
