Prepare for Apple to drop support of old media formats in macOS 10.15 with IINA Video Player

“Unless you follow all the links in our Watchlist items, you may have missed this ominous message in Apple’s release notes for Final Cut Pro 10.4.6: Detects media files that may be incompatible with future versions of macOS after Mojave and converts them to a compatible format,” Josh Centers writes for TIDBits. “That’s right, Apple is dropping support for some media formats in the next major release of macOS because the old QuickTime 7 framework isn’t 64-bit friendly.”

“Thankfully, the industry has now largely settled on H.264 and H.265. But if you used to dealing with transcoding video (or let’s be honest, downloading it from shadowy sources), you’re probably wincing right now,” Centers writes. “And even if you aren’t, you may very well have old videos in obscure formats, as might have happened with video taken with a flip phone.”

“There are many open-source video players, the most popular being VLC, but there’s one that’s both better and Mac-exclusive: IINA,” Centers writes. “It’s free, it’s open-source, it’s built for the Mac (written in Swift even!), and it hit 1.0 at the end of 2018 (I’m reviewing version 1.03).”

MacDailyNews Take: If you haven’t tried IINA on your Mac, or for that matter, the must-have VLC, download them and give them a try today!


  1. Longtime Quicktime 7 Pro user, VLC too.
    Will be sad to see QT 7 go.
    Highly recommend IINA for far better subtitle control than VLC or Quicktime. Very intuitive.

  2. I wonder if the group of people that need QuickTime 7 are the same group that had fall detection turn on automatically on their Apple Watch?

  3. I assume it’s due to Apple going 64bit only?
    End of an era, although in reality it ended some time ago. Hopefully the majority of us have moved on.
    I wonder if Apple are doing this now because ARM Macs will only be able to execute 64bit?
    Either way it makes sense to drop 32bit so you only have to focus and optimise the software and hardware for 64bit. We don’t wan’t to be like Windows and have tones of legacy code.

    1. “ARM Macs will only be able to execute 64bit”
      I think this is very likely. It’s not like Intel’s processors suddenly won’t be able to use 32bit instructions. And, not only is there legacy code, there’s legacy structures INSIDE all Intel chips that deal with processing all the different forms of legacy code they support. This brings with it a lot of overhead and context switching so, right off the top, there’s a chunk of performance that any ARM macOS system won’t have to lose.
