Best Operating system for old pcs and Mac

I was struggling with my MacBook Pro Mid 2009, so malicious program deleted UEFI from my pc, can’t install (since I purchased more than 6 years) OS X El Capitan one it(stupid and you can’t
update to future versions to run most advanced XCode to program on swift).
now it’s time for most secured Linux distribution called Manjaro XFCE.
guess what the latest can run your pac, and manjaro saves you if you committed mistakes by installing the new kernel and become dead simply by booting from same flash memory and get
all your files back to you once you click on browser of files (mount).
so you can get the hard disk entirely formatted safely by manjaro.
try open latest of firefox or VLC player, you got your pc frozen (why since they are not
compatible with old pcs or macs) so the following:
go to start menu click on add or remove programs. remove both of them VLC player, and FireFox
then install Chrome(called Chromium) and install MPV video player and SMplayer to run all
video files.
check it out, now you got most advanced operating system in the world(which is Linux)
and most updated, and anti hacking and most secured from viruses as well.
don’t forget to install brightness controller to adjust brightness and color of your screen.
listen to warning and don’t install anything you warned about.
to run windows programs; don’t forget to install “Wine” to run all windows programs.
WISH YOU ALL GOOD LUCK IT’S THE BEST OF PROGRAMMING ENVIRONMENT AND I TESTED
KDE AND SEVERAL DISTRIBUTIONS(LIKE UBUNTU OPEN SUSE…ETC) FOUND THIS ONE
THE BEST(MAJARO XFCE) AND HAS NO HARDWARE PROBLEMS
