Dear Sir Jake Lo can you help me? I want to install OSX 10.13 and My hardware information : MSI X299 SLI PLUS Intel 7820X SAMSUNG 960 EVO 250G M.2 NVMe G.SKILL DDR4 3200 8G * 2 GIGABYTE AORUS GTX 1080Ti thanks.

my monitor does not have an HDMI connector. and I can use dvi normally. ssd fast using apfs, here is my test data: ➜ ~ time dd if=/dev/zero bs=1024k of=tstfile count=1024 1024+0 records in 1024+0 records out 1073741824 bytes transferred in 6.166212 secs (174133132 bytes/sec) dd if=/dev/zero bs=1024k of=tstfile count=1024 0.00s user 0.42s system 6% cpu 6.221 total ➜ ~ dd if=tstfile bs=1024k of=/dev/null count=1024 1024+0 records in 1024+0 records out 1073741824 bytes transferred in 1.894809 secs (566675491 bytes/sec)

This efi compression package there is no APFS driver, you need to add to the installation, otherwise you will not see the hard drive.

Thank you very much, I changed the DVI can be displayed normally, I really did not expect because of VGA
