Problem to install OSMC

I download osmc installaer for mac
i selected the last 2017.07
but when tried to install on SD card (new microSD card SandDisk 16GB HC I)
show this error “an error occured extracting the archive! Please consulte the log file”
But i can’t see the log file on desktop.

I tied also to download last “OSMC_TGT_rbp2_20170803.img.gz” for raspberry Pi2 and use this local file, but it shows the same error.

Thanks
