Thanks, I'll probably do the upgrade in the Spring and see if prices drop further. My computer is working fine now....However, there is some question as to whether I will need the digital thermal sensor cable??
With a 2.5" SSD - I have found you don't need an OWC temperature sensor for it - I've only had fans ramp on 2015 iMacs with HDDs that were not Apple HDD.
If you're using a flash SSD, you do not need a temperature sensor either, you would simply need to remove the SATA cable if you are removing the HDD as that would cause the fans to ramp.
The only other issues that I have before making the swap is the fact that I don't think I'll be able to do a restore from my Time Machine backups...I believe that since the Fusion is actually two separate drives that the machine will need a fresh installation of MAC OS and won't be able to restore from back-up....am I correct?
OK, just to get an official definite answer I called Apple Support which has always worked great for me.
There is no issue in restoring a Time Machine Backup to the new SSD drive coming from my Fusion Drive....However, the Time Machine Backups will not longer work correctly to restore backups on the new SSD once the OS is restored.
You need to make new Time Machine backups from the SSD drive for it to work correctly which is not a problem.
Once I've migrated my backup to the new SSD from Time Machine, I'm going to wipe the Time Machine drive and use it for the new SSD installation.
Hope this helps someone also looking to do this.
Done!....that was easy...
the hardest part, other than using a couple guitar picks to open it up (and it wasn't too hard really) was figuring out how those damn display cables are connected to the motherboard....
I didn't want to break anything and couldn't figure out exactly how they disconnected...took almost as long to do that as it did to peel open the case.
I already created a new backup from the SSD image in Time Machine....Piece of cake!
