I have a 2015 (purchased in late 2016) Macbook Pro with the following specs :
- 2.5Ghz Core i5
- 8GB of RAM
- Running OSX El Capitain 10.11.6
It downloaded Sierra and is asking me to upgrade to the new version.
I want to do it, but I'm worried that the new Operating System will be too demanding for my laptop or that there are some things that I won't like, and I might want to revert in the future.
If I install Sierra, will I still be able to restore my Macbook to factory settings (including El Capitain) by doing a factory restore (where you hold CMD+R while it's booting, and format the drive to reinstall the OS) or will it always default to Sierra instead?
