I have a big issue with new Osx MOJAVE and Lightroom CC ver. 2.0 on a Macpro with ssd/32gb/6 core + Dell 4k 32 inch. and double graphic card AMD FirePro D300 2gb ram. The scrolling gallery is very very slow at all screen resolution, isn’t possible to work fine. Does anyone have the same problem? No problem before upgrade to Mojave with the same system/Lightroom version. I tryed to uninstall/reinstall Lr with two reboot but the problem isn't solved. I'm very disappointed, it's crazy that with my old Macbook the speed is ok and with an expensive/professional system it's impossible to work.
