I knew it was going to come but didn't know when. With the dropping of support for MacOs 10.14, I can no longer run the latest version of Lightroom Classic on my mid-2010 MacPro with its 48 GB of RAM, upgraded GPU, 5 internal hard drives (including 2 SSDs), eSATA interface, etc. What to do? I'm not looking forward to the painful and expensive process of getting a new computer. I suspect I'm not alone.
Hello, 2009 Mac pro user here.
Two things: the mac OS update, and your intel chipset.
You can bypass the mojave/catalina restriction by using dosdude mohave patch. It allows Mojave/catalina updates on unsupported macs.
http://dosdude1.com/software.htmlWhen Apple moved from el captain to mohave, then to catalina, the assumption was that everyone was working off SSDs, not spinning platters. So read Dosdude's suggestions how to handle that. Apple changed their filesystem to work more efficiently with SSDs. in english that means a headache for those of us who don't drop $5K a year on new computers.
The 2nd part is the chipset. My 2009 doesn't support this on chip instruction sets called SSE 4.2. I think it uses 4.1. Software like Capture One started requiring this in 2020, as did Photoshop and lightroom 10 I believe.
These were the new minimum, intel requirements for Adobe 2020 products:
"Intel processor with 64-bit support; 2 GHz or faster processor with SSE 4.2 or later"
I think your 2010 does support that, so you may just need DosDude to hack your machine to catalina and it should buy you some time.
For others erasing this, here are some work arounds the SSE4.2.. I may try this with my 2009 mac pro:

In a nutshell this patch:
"MouSSE traps illegal instructions in both privileged (kernel) mode and unprivileged (user) mode, and emulates the POPCNT, PCMPGTQ, and CRC32 instructions. As of this writing, PCMPGTQ and POPCNT are the only problematic instructions used in the AMD drivers. (And, apparently, the only two currently used in World of Warcraft.)
MouSSE is fully reentrant, and automatically runs on all CPUs/cores/threads."
The good news is that these new M1 pro and Max chipsets.. if they wander into mac mini pro or max soon, this would be and ideal replacement . the current M1 mini is no slouch, with an even better HDMI 2.0 vs the new mac pro HDMI 1.4. However since I'm video editing curious, having video encoders/decoders in chip seems invaluable.
I hope this helps you squeeze another year out of your mac pro. however realize.. we are really pushing these machines... I already swiped out a faulty ram riser on mine. I also use the windows boot for, uhm... "productivity apps" like battlefield!
. Great machine, but the writing is on the wall, and the ceiling.. and the floor!
