Used it on a MacBook Pro 2010.
Reboot - not detected, has to force shut down.
Using it after startup is bad, runs like a 7200 RPM HDD, on my previous OCZ Vertex3 SSD, it takes 2.5" for a heavy weight app like Photoshop CS6 to start up (after reboot)
On the Intel 530, it takes >10s (this is after reboot).
It is extremely slow and it was a big letdown. I've since sold the drive off and replaced it with a Plextor M5 Pro instead. Now my operating speeds are back to normal and to what feels like SSD speed.
Hope Intel resolves this soon.
