I have OS X EL Capitan Version 10.11.6

Yes my computer is old but works great.

MacBook Pro 13 inch Late 2011

I had the hard drive switch out

I have 2 memory module 1333 Mhz DDR3

have 724.86 free of 998.98 GB

I have enough room for new version , but will not let me.

Why do I have to get a new computer when my works fine.

I do not know much about computers ,

all I do is emails and pay bills and buy thing on the internet, but my version on Safari, is way out of date and I can't get the new one

can anyone help me with out buying a new computer ??????
