Has anyone (besides OWC) reverse engineered the sensors required to make the 2009-2012 iMacs work with 3rd party hard drives? The OWC in-line digital thermal sensor products work great but they cost almost as much as a 120 - 240 GB SSD that are affordable to keep these old machines going. If someone could make and sell these for half their cost or less I think there would be a lot more people keeping these old iMacs going. They’re still useful.
