Where to buy IR Sensor Replacement

Hello all,

I recently purchased your dual hard drive kit for my late 2012 Mac Mini. Your guide was great, the instructions were very easy to follow and I had no issues. I disassembled the machine per instructions, added the extra cable in, reassembled and started the restore from a Time Machine backup process.

And that's when the problems started. Every permutation of restore OS X failed, clean install, restore from Time Machine, restoring the HDD to the new SSD, etc. And I know it wasn't an issue with the SSD as I had that working without any problems in my mid 2007 Mac mini.

So I start to disassemble the machine one more time, and I've pretty much got everything memorized. That is until I forgot to unplug the IR Sensor from the motherboard before sliding it out. Ugh. I swapped the locations between the stock HDD and SSD. Reboot into restore, cue up the Time Machine Restore overnight and it's working AOK.

Two questions: I see you have a guide on how to replace the Mac mini late 2012 IR sensor, but can't seem to find any online, is this a part you sell or do you know where I could get one?

2nd question, is it possible there is a fault with my 2nd cable since even the clean OS X install would fail on new SATA cable with the Dual Hard Drive kit, but everything worked fine on the factory SATA cable? I don't think the cable is 100% defective as it never had issues recognizing the SSD drive, or the now factory HDD hooked up to it? However it would fail at random times during the OS X clean install and also at random times during the Time Machine restore...

Thanks in advance for your time...

can you confirm if you had erased the data off the SSD after it was taken from your old mac mini? also, had you cleanly installed 10.8.1 or later before beginning the migration?

Its odd that it worked in different orientations, as both slots are the same interface, unless the cable wasn't seated properly the first time.

there is a cable here though:

It could be that the replacement cable is fine, it could just be interference problems. The SSD you have will have to have been a 3G drive to work with your 07 Mac Mini, but it could be a revision of SSD that can auto switch between 3G and 6G, can you confirm what speed drive you have? as your SSD may have been functioning fine on 3G, but with the new cable it could be causing interference with 6G data speeds.
