Mojave is now running on cMP 5,1 Intel 6 core 3.46GHz, Radeon 7950 (Metal compatible), 32GB RAM. It needed a firmware update prior to install.
After that was done, Mojave installed just fine. I made sure to disconnect all RAID and single media drives just in case.
Done installing.
Firmware has been updated to Boot ROM Version 138.0.0.0.0
Only thing not working is Airdrop sharing. Apparently cMP 2012 are not compatible.
AirDrop system requirements
That's a real drag Apple!
Working on a short and small multicam project in FCPX 10.4.3 with 4K footage in a 1080p Timeline. I'm letting FCPX transcode the XAVC Long GOP and h264 originals to ProRes422.
Slowly working with the originals until all the transcoding is finished in the background. I can perform basic editing in Multicam mode without much problem although it is pretty sluggish each time I stop/play or try to scrub.
After transcode and waveform generation is completed, everything is very responsive. Moving quickly through the first cut. No weird behavior, no hangs to report.
Exporting a h264 one pass TC screener via Send To Compressor was at first about real time: 15min. Timeline compressed in 15min. After the second and third export for screener 2 and 3 the time went down to 8-7min so half real time. Not too bad.
Just tried a few BruceX exports and got 44sec. Not great, not too disgusting either.
