I am using sys9.2 and Rei 3.6 on 10.7, so I guess our setup is pretty similar.
Therefore:
YES it works..and pretty good tbh.
N3DS work:
1. Copy ntr.bin to the root of your SD card
2. Copy BootNTR.cia to anywhere on the SD card
3. Install BootNTR.cia with a cia Manager of your choice
4. Start NTR CFW by launching it from your homescreen
5. If it says successful, return to homescreen.
( else -> reboot NM3ds and restart from 4.)
6. Press X+Y on your N3ds and select 'Enable debugger'
PC work:
(after you enabled debugger on N3ds)
1. Start ntrclient
2. enter connect('N3DSIPADDRESS',8000) (e.g. connect('192.168.1.111',8000) )
3. enter remoteplay();
Start NTRViewer.exe
If this quick stepos were not sufficient, look on the guthub page, there it is explained with more details.
Kind regards, Sno0t
