Q: Does Mac EFI 2015-001 Update change the OS set by default for my MBP?

Hello,

 

I have MBP 17 late 2011. It comes with Lion, and I updated it to Mavericks. I don't want to update to Yosemite or El Capitan.
And I want to keep my clean install sequence - the OS downloaded by default is Lion.

 

So my question is a little bit dumb may be, but I want to be sure.

 

Does Mac EFI 2015-001 Update change the OS set by default for my MBP or not?


Thanks in advance.

MacBook Pro, OS X Mavericks (10.9.5)
