UPDATED INFORMATION
So, while I don’t have any Windows machines here, I do have another Mac, so I disconnected Roon core from my iMac and went over to the other MacBook Pro.
I deleted Roon from the Applications folder on the MacBook Pro, changed the name of Roon in the Library folder to Roon-old, and downloaded the Roon core software for Mac from your Roon site. I created the new Roon core and after authenticating I proceeded to play music to my Blusound NODE from the MacBook Pro. If plays just fine - from the MacBook Pro.
I went to Settings->About and Roon started downloading and then installing new Roon core software. After about 30-second, I got the EXACT SAME error message as I did on my iMac: “There was an error checking for an update”. The MacBook Pro is a 2016 15-inch, 2.2 GHz Quad-Core Intel Core I7, with 16 GB of RAM, running macOS Big Sur Version 11.7.9. Different processor, different OS, so it seems like the hardware is not causing the problem, unless there is some setting in the OS on BOTH machines that is not set up to Roon’s liking. I also made sure there were NO OTHER Roon DMG files in the downloads folder, as was suggested above.
So, on two separate MacOS machines, I cannot automatically load new core software, and I cannot manually load new core software. The first failure is not operator error. The second failure may be operator error, but I believe I’m following ALL the instructions provided to install the software manually. When I install Roon core on a virgin machine with NO core software anywhere on the machine, my manual download worked fine (last year).
I bet, if I buy a new virgin, non-Roon Mac, I will be able to download the updated core software just like I did last year, and can then copy the correct version files over to my iMac, but that seems like a very expensive work around just to get updated software.
The operational problem I have that is very frustrating is that my iPhone and iPad have automatically updated to the new version IOS Roon software, so they won’t operate now with my iMac or my MacBook Pro to control Roon. I can certainly run back and forth between the home office where the iMac is and the family room where the Bluesound NODE and stereo system. I can change songs and playlists on the iMac and then run back and listen to them in the family room, but is that how Roon is intended to work. It also makes it hard to look at all the tremendous metadata that is the main reason I’m paying for the Roon subscription.
Clearly, there is some other bit of metadata that is stored some other place on both Mac computers when Roon core is installed on a Mac. This metadata or file or whatever does not seem to allow the new version software to be installed. Hence, the error message on both machines.
The error message doesn’t just appear by itself, It must called by some line of code when certain conditions exist. Can’t a software programmer find those lines of code that call the error message so they can find out WHAT is causing this error.
Please advise. It looks like I would be listening to Roon over this Labor Day weekend!
