That has been my favorite Apple fuckup in recent history, because I still see a lot of tifs from designers, photographers and other artsy types, who have traditionally been the folks keeping Apple alive. It's kind of Apple since the iPhone in a single poorly thought out patch."What's that? All your .tifs are now giant black squares? Well, you shouldn't be using .tifs. It's an ancient yukky format and it was either patch our shitty operating system against 'malicious tifs' or fuckin' rewrite your shit so that your data is gone and we all know how you'll fare in that discussion."
Buddy of mine compared this to that moment where the cops come in, turn on the lights, shoo away the DJ and say "awright, party's over, everyone go home or we'll crack skulls" causing the crowd to disperse from the warehouse and nurse their high at Sheri's. I had those. All six of 'em. They were sold at 36x24. I paid $5 ea to scan them in at 600 dpi then sold the lot on eBay for $150. They're $60 each now. And I have 600dpi of black. All six of 'em.
I use ImageMagick to do things like that, it's remarkably lightweight (nowhere near the disk space required for photochop), but still very powerful. And not that you asked, but after I've built all my image frames from the data, I stitch them together into .mp4's with ffmpeg. Video data products are so obviously the future, but don't tell all the old men who still get printed journals delivered to physical mailboxes.
It's so too late, dude. Apple rewrote them. And when I looked at my time machine backups on Apple, it rewrote those, too. Theoretically I could have attempted to mount time machine stripes on my Windows machine and hope for the best but the act of looking for them in OS X destroyed anything that wasn't destroyed.
