Q: Planning to go in for a Macbook Pro mid 2012 model having Mavericks for editing video in FCPX...is this model for me:Apple Macbook Pro MD101HN/A 13-inch Laptop (Core i5/4GB/500GB/Mac OS Mavericks/Intel HD Graphics), Silver

FCPX demands macOS 10.10... minimum.

No, haven't said that!

Just mentioned the min. specs for FCPX in reply to your post mentioning 10.9.

For sure you can upgrade a MBp 2012 to 10.10, 10.11 or 10.12…

take into calculation extra $$$ für Ram, 4GB is … weak. No fun with longer/complex projects.

What Karsten said; in the US, a 16 GB RAM upgrade costs about $100.

Also…if feasible, spend some time on an equivalent machine to see how comfortable you are with the 13 inch display before completing the purchase.
