Thanks. I don’t disagree with any of that. I had my own mid-2009 cheese grater until earlier this year, to which I have done a lot of upgrades over the years. But in the end, I needed a better machine and gave it away to a student rather than deal with eBay, Craig’s list, etc. A new iMac more than replaced its functions.
But, yes, I know that there are plenty of older Avid installations still running on old Mac Pros. They are workhorses. However, the software industry has move to 64-bit and that’s a clear demarkation for both macOS and Windows. In that process, the OS versions have finally gone exclusively 64-bit and thus deprecated all 32-bit dependencies. Therefore, app developers have had to follow in the same direction.
Honestly, I have no idea whether or not old Mac Pros have the hardware capabilities to only run as 64-bit machines or whether there are real limitations. Or whether it’s simply Apple restricting the OS installation.
Maybe under Boot Camp, you could install Windows 10 and the newer (Windows) applications you want. I haven’t tried it and haven’t heard of anyone else doing it. There are plenty of cost-effective PCs that will blow the doors off of any old Mac Pro, no matter how upgraded it is. So probably people going Windows have gone that route instead.
My point is that you still have a very useful Mac Pro that can still run software within a couple of years of being current. But you are essentially frozen in time. That’s not a bad thing. Think of it as driving a reliable 10-year-old vehicle instead of moving up to a brand new Tesla 🙂
