I fired up Audirvana Plus again, switched on the System Optimizer and started playing a track. This was accepted and the permissions were correctly set:īut I also had to change the group from admin to wheel (this had probably been changed when I’d been trying to fiddle with the permissions in Finder) so: sudo chown root:wheel PrivilegedHelperTools and everything was finally right:

I’d have to type in my password to confirm. Instead of chmod 755 PrivilegedHelperTools I needed to type sudo chmod 755 PrivilegedHelperTools. It turns out that you can force commands to happen by proclaiming yourself to be a super user. I think what was happening was that as this folder is a system folder not even admins can fool with it.

, huh? Except that permission was refused, even though I am admin for the Mac. So it was just a matter of typing chmod 755 PrivilegedHelperTools. There was PrivilegedHelperTools with root ownership, but in the admin (rather than wheel) group, and with the wrong sequence of r and w and xs:

commands to get me back to the root, then cd Library and then ls -l to show the contents of the folder including the permissions. You need to use Terminal and the chmod command. More time with Mr Google revealed a site that explained the relationship. But these are all rwx, nothing to do with 755.

So I find the referred to folder and with the help of Mr Google managed to find out how to change permissions. I said ‘Yes’ and was invited to enter my password, and then a system message appeared: When I double clicked on a track to play, the program told me that the Optimizer had to be installed. So, it was easy to switch on in the Audirvana Plus preferences. But I’m recording it here, in part in case I ever have to do it again.

That turned out to require delving into some nasty deep Mac stuff. So I decided to sort out System Optimizer. Last night, though, I was streaming a couple of 384kbps tracks and DSD128 ones and there were some hiccoughs. I tried to use it but got an error message, and haven’t bothered again for a few months because I was getting clean playback most of the time anyway. The DSD uses the DoP protocols (DSD over PCM - the DSD is disguised as PCM in order to trick the USB circuitry).īut Audirvana Plus also has a cool feature called System Optimizer which gives it priority over a whole bunch of other Mac processes in order to reduced the chances of interruption. It has lots of nifty search functions, and can stream DSD, plus PCM up to 384kHz, to any DAC which supports it. So after doing some research, including using the excellent The Well Tempered Computer as a resource, I decided on Audirvana Plus for the Mac.

, for Music I used a free package called Vox for a while, but then I started reviewing DACs that support Direct Stream Digital streaming and Vox didn’t support this.
