Bought this to replace the 1TB HDD secondary disk in my Macbook Pro (using the DVD Slot) - Nice and quiet drive at a very competitive price from CCL. (Always check their website price plus delivery against their eBay store with free delivery as they are often different!)
Like most drives nowadays this is shipped un-initialised and the Mac's disk utility is not the easiest to use. So save yourself some time and initialise it with a GUI-ID Partition Map using a windows command line first - before plugging it into the MAC !
