I'm a totaly noob and need some help understanding how to install a new Samsung 840 EVO and updating to the new firmware (april 2015), which fixes the issue with read speeds of old data. I bought a 500GB Samsung 840 EVO and then found out about the issue before installing the drive. So it's been sitting in a drawer unused this whole time. Now that Samsung has just released a good fix, assuming the fix solves the issue for Mac users, I want to finally install the drive. I'm on a Macbook Pro early 2011: 2.2 GHz Intel Core i7 16 GB 1333 MHz DDR3 AMD Radeon HD 6750M 1024 MB OS X 10.9.5 1. Is the issue actually resolved for Mac users? 2. Are there any guides, resources for installing the drive in my Macbook Pro early 2011? I know close to nothing about this. 3. Do I need to use the Samsung data migration software? 4. Do I need to update my OS? 5. People have mentioned having to install separate TRIM software. I don't know what this is. Is it necessary? 6. In forums, it seems like there are directions for installing the firmware. Is there anything I need to do differently since the drive has never been used/installed? Thanks in so much in advance so any insights for this noob!
