I don't see the point of keeping OS X Yosemite 10.10.5 on my MacBook Pro, Core i5, software is so old SSL certificates are out of date, I can't update neither the stock software or any application - eviltoast

MacBook Pro, Core i5, 2.8 GHz (I5-4308U), model A1502 (EMC 2875), Retina Mid-2014 13", MacBookPro11,1, RAM 8 GB, VRAM 1.5 GB, Storage 512 GB SSD

vlc, tor, brave, firefox… are apps that I cannot download. Neither can I use mac’s app store, because software is too old.

What would be the point of not nuking this OS X?
