I have a T530, whit Catalina working perfect, this week I buy a cheaper T530i, try to use the same process I do on my first, but my screen split when enter macos (installation and installation done), on external screen work perfect, I try many things found here, other forums and other...
Follow many tips on this forum, I succeed to install Mojave on a thinkpad X230, I think all is working well, only thing I cant put to work is the 3g card ericsson H5321gw, I need to do another little things like remap some keys in keyboard too (language portuguese, dont configure well)...
I spend some time reading this forum this days, I think in try run "hackintosh" in my computer, I have a good pc for my use, since I buy a new ssd this week, maybe I can try do a dual boot with windows?
My specs are:
ROG Maximus VII Impact (Z97)
MSI GeForce GTX 1080 Aero 8G OC
