I just licensed the full CC (all adobe products) and installed on my MBP and Lightroom Classic will not start. Icon appears, splash screen appears then immediately disappears. The cloud version of Lightroom works. Photoshop works. Same version of LR Classic works on my 2013 Mac Pro (6 core, 64GB, 1 TB, Promise Pegasus 2 8 bay raid (location of catalog)). No error messages are given.
15 inch 2016 model with touch bar: 2.9 GHz i7, 16GB 2133 DDR3, Radeon Pro 460 w 4Gb
High Sierra 10.3.4 everything 100% up to date
4TB OWC Thunderblade connected via TB3
I have done the following - all failed
Uninstall and re-install LR Classic
Log out of CC, reboot, log in
Start in Mac safe mode
Changed power setting removing graphics switching (forcing use of the Radeon over the Intel graphics card)
Searched forums, searched google and searched online help and found nothing substantial. Many windows users seem to have similar problems. Nothing has worked. Any and all help greatly appreciated.
I run Intego 10.9 on both machines (virus protection etc). My desktop has 2xD700 GPU's (runs fine there). I have also detached the Thunderblade and rebooted and tried JIC that made a difference. I attempted to find the AutoBahn setting in the preferences - found it but there was no true/false (to disable GPU on the MBP).
