Hi, I have MacBook Air (early 2015). I replaced it’s SSD with a MacBook Air (2013) sm0512f SSD. Now I’m encountering some issues: My devices goes into waiting state after I open the lid.My device goes into waiting state after I wake it up from sleepSometimes it does just go into a hang while browsing my drives files I literally have to restart my system 3 times. Is this because of El Captan? Will changing my OS work?? Or because of sm05112f isn’t compatible with macbook air2015? Really appreciate your help! Regards
Sadly you can’t use the older SSD in your system. The SSD’s firmware on the older SSD is not compatible with your system. In addition you’re limiting your systems performance. The newer SSD is a full PCIe implementation unlike your older SSD which is running in mSATA mode. I would recommend you get the correct Apple SSD for your system or you could install this 3rd party SSD which just came out (Feb): OWC SSD upgrades for MacBook Air 11" & 13" Mid 2013, 2014, and 2015
The SM0512F SSD works with a MacBook Air 13,3“ early 2015 and High Sierra 10.13.5
