Do you know what drivers/software are missing or is it maybe just an user error? It hasnt been clear to me which software/drivers op is talking about.. and if i read it correctly the drive is already 6yo old. And you can also ask why apple doesnt provide support for their own software to work with their own released os’s. why always blame other companies when even apple doesnt support their old os?
2. Why is it always to blame hardware companies when e.g. Apple releases a new os which drops support for current existing hardware? Why not blaming apple changing the code that current existing working drivers wont work anymore? as you probably know, macos has needed several times special drivers for other hardware to work - e.g. something so simple and worldwide thing like writing for ntfs which should be as a standard and all os should provide it without needing to get extra softwares...
Did apple even bother to check when they realease a new os, how many working hardware wont work and need a new special drivers etc? Think about Microsoft and windows. If MS would release a new os dropping always support for existing hardware/software, it would be a catastrophe... Still, there are million differend variants (built computers) and releasing a new version of Windows doesnt usually break anything. How is even possible that MS is able to do this when sometimes apple doesnt seem to be able to control their own hardware/software?
