Pros: After looking into the "compatible" drives and seeing there are sleep issues etc. I've also had an issue with one well regarded brand in my Mac Pro. I decided I didn't want the headaches. It's my wife's computer and I just want it to work right the first time and every time so I bought Apple. I dropped it into my laptop and it booted into the OS upgraded to Catalina, no problems. That's how replacement parts should work.

Cons: A bit expensive compared to other brands for the size of storage.

Overall Review: I would recommend this for a trouble free upgrade.
