@jalefkowit yes, that's what I do now. I swap bits that are either malfunctioning, broken, or unsatisfactory. That is what I don't get the 'upgrade' thing now.
Even when my 10-year-old MBP actually died, I refused to give up, and found a new logic board on eBay (which, lucky me, had a more powerful CPU soldered in), so I still use it today, and it's even faster.
Maybe I'm just too old for this stuff, or I might have left capitalism without realising it.
