It is quite simply insane that Apple, the it-just-works company, the company with more resources than literally any other on earth, has let it come to this. These hackish, kludgy workarounds for something so basic as rotating a video in one of its core software products that ties in with hundreds of millions of shipped devices.
Apple really and truly doesn't care about its software anymore, and even more so its Mac software.
Ok, who's going to the the first "Level 9" to tell me and others "if you don't like it, just use something else"? My response is a) I guess I'm still clinging onto the days when Apple built software with care and competency, and b) If you use products in the Apple ecosystem, they are supposed to tie together, and supposed to work together, and it ain't just that easy. Obviously. Many people once willingly paid extra for Apple hardware because the software was so much better; Apple proves time and time that they've forgotten/forsaken that. They no longer care about delighting customers, only locking them in.
So yeah, you (still) can't rotate the videos in Photos? C'mon. Ridiculous.
And yes, I've sent Apple feedback, down that worthless black hole.
