Does this fit a 2012 Macbook Pro 15'?
Hello I am going to purchase an SSD sandisk and am not sure if one size fits all...
Yes, most 'internal' SSD's are the same size. You need to research about enabling TRIM when doing the swap. Apple enables this feature on it's SSD's that ship with their Macbooks, but needs to be enabled in aftermarket (Non Apple SSD) swaps. Backing up using iCloud and doing a clean install of the OS on the new SSD works well for me. Migration Assistant was not an option i recommend.
