FLAC On A Mac


I know this topic appears here often but it seems to change every time I try to do a download.
I have a 7 year old MacBook Pro that i recently changed to OS to El Capitan after endless badgering from Apple to do so.  I previously had both XLD and Decibel on my OS for converting FLAC to Mac Compatible formats for the few downloads that I had ordered from HD Tracks.  
  I hadn't listenedto these downloads since the afore mentioned conversion.  i just ordered a new download (24 bit) from Presto Clasical and now I am getting messages that both programs will not work because they are from unknown developers.  Why these developers have become strangers to Apple after happily coexisting with them is another story but can someone tell me what the current best program for playing these files is>  My Internet search is unhelpful as everything seems to be recommending these two programs

"Oppo will play WAV, not AIFF." That is not correct. I owned an Oppo 105 and 105D and both play AIFF fine. I did this using the digital inputs on both the front and the back with no issues. Seen many other Oppo owners do the same.  

What do you mean by "monitor"? Hardware, software? The only monitor I know of is a pair of small speakers used in a studio.

For mac music software, Audirvana+, Amarra & Pure Music are the top ones. You can trial them all & decide for yourself. JRiver was made for Windows, and just recently released for Mac to mixed reviews. I haven't heard it so no opinion. Cheers,

I took the Oppo data from their web site, which mentioned playing WAV and didn't mention playing AIFF.  In my experience when a component doesn't mention compatibility with a format that means it won't play that format.  I am glad to be corrected.  Actually, I added a VIDEO monitor to my OPPO, and am playing the flac files on it just fine  Problem solved, set me back $100.00 but what the hey, I'm happy

Since Apple has legal interest in AIFF and some companies don't pay any fees to Apple they get uncomfortable mentioning AIFF compatibility. Ran into that with a few portable digital players too. Cheers,
