Goodmorning everyone
I own an imac 27 late 2013 with only an integrated 256gb ssd blade, since the video support spring broke, I wanted to take advantage to add an internal 2tb ssd. I found an ifixit upgrade kit,
but I have 2 doubts
1 the kit requires the replacement of the existing hdd, so will I also need the connection cable to the motherboard?
2 leaving the s.o. on the standard ssd blade and adding a second ssd can create a boot problem?
I thank you in advance

I think the cable for the HDD bay is only present if your unit shipped with a HDD.

So you would need a replacement SSD blade. Replacing the SSD blade is a much more involved process.

It's recommended if the computer is working fine to update Mac OS to the latest version PRIOR to doing the upgrade to get the latest bootrom update.

You can try to find an OEM SSD second hand or get a 3rd party SSD such as OWC Aura Pro X2 SSD.

If you use bootcamp you'll want to get an OEM SSD.

If you get the OWC Aura Pro X2 SSD you must have updated to at least 10.13 High Sierra with the factory SSD installed PRIOR to replacing the SSD. If you don't do this the system will fail to boot.

I just completed an upgrade on my late 2013 IMAC. I bought the 1TB PCIE from OWC (Aura X2) and kept my old HD for storage purposes. I followed OWC's directions (video) to the tee and it was super easy. Took me about 1 1/2 hours because I was taking my time. Using OWC's upgrade kit and had no problem at all with any of it. I recommend that you take your time getting all the old adhesive off using "Goo Gone" .... works fantastic. Then clean all surfaces with rubbing alcohol before reapplying the new adhesive. Well I have to tell you that the results are UNBELIEVABLY FAST. Using the app BlackMagic, I was able to increase my read speed 22X. Here are the before and after results. Honestly, no one should be afraid of doing this upgrade if you take your time.
