I am starting this thread to make people aware of some issues with mountain lion gm and certain ocz ssds. As you all know mountain lion gm was released to developers not long ago, and people with non-apple ssds may have some trouble when upgrading to mountain lion. My friend and I have done some testing with 3 ocz ssds over the last week and 2 of them simply won't work correctly with mountain lion, these 2 being the ocz petrol 128gb and the ocz octane 128gb. In both situations, will it be through an upgrade or a fresh intall, you cannot boot into the OS after installing on to these devices (unless in safe mode). You basically just get a boot loop every time you turn the computer on. The other tested ssd was an ocz agility which worked flawlessly. The link below is from the ocz forums and they are fully aware of the issues, http://www.ocztechnologyforum.com/fo...Octane-1TB-SSD but it could be some time until either ocz or apple does something about it, which if you are like me, is very bad news, I purchased the ocz petrol only 2 weeks ago, it works great with lion, but my guess is that with mountain lion apple are trying to make it harder to install their new os with non-apple hardware. So this thread is just a warning that if you intend to upgrade to mountain lion in a few days time, there is a good chance that if you are using non-apple ssds, you may experience some problems.
