Wow, that was fast and smooth. It seems that OCZ has done a very good job on providing support tools for Mac users. I don't know if that was the case in the previous years but I just flashed the latest firmware to my Vertex 3 SSD in 10 seconds, rebooted and I am up and running again!
All you need is actually go through the very simple steps as described here. Get an empty usb flash drive, restore the image as download from the OCZ site to the flash drive, reboot your mac from the usb stick, go to tools -> update firmware and it is ready.No errors or surprises at all.
The latest version for my drive is 2.25, release notes on the update can be found here. Nice!!
