Modifying “Remote Disc” requires an administrator name and password.

Hi, I've had this issue as well and just called Apple support to see if there was any further update, they suggested I check if I was on the latest version of Mojave - I wasn't I was I was on 10.14.2 - I updated to 10.14.3 and it now works the same way it used to. Disc appears on the desktop, drag files to burn, burn, job done.

Same is happening to me. I have a regular external optical drive. I get the authentication error when I try to drop and drag a folder onto the optical disc in the finder folder window. The DVD doesn't show up on my desktop as I have the preference to do so, but the drive shows the drive utility, etc., etc., essentially everything looks okay except the disc never shows on the desktop as a writable disc. I was able to go to the finder, select the folder I wanted to burn, cmd+click, or in my case, a two finder click and ask chose the burn option. It is currently burning.

Selecting all the files to burn and then right clicking on them to choose "Burn" worked for me. I am running macOS Mojave 10.14.2

Remote Disc is not your blank disk. It is for using a CD/DVD drive from another computer.

Well, after months of this issue I got a wonderful APPLE help session today. My disc burner does everything but burn the way it used to except eject and burn. Now when I want to burn songs I need to hold down control while hovering over the picture in playlist (the one with several album covers at the top, I need to have the list all ready to go first and the blank cd in the burner). When you hold down control on the 4 covers, BURN cd shows up... I just hit that and WOW magic... Try something similar. The way that did work...DOES NOT... Good luck

I spoke with an apple chat last week. Nothing fixed yet. If you need to burn anything there is a way around. I am holding out til this is fixed. But you hover over the song or file or photo and select it and somehow there is an option to burn. It’s a backdoor way but I’m holding out a bit longer. I advise chat on line with your issue. Everything gets logged and mass quantity = strength in numbers. Maybe a fix will happen sooner? Let’s cross fingers.

Same is happening to me!!! I last burned PHOTOS to a disc in September. Your post is NOVEMBER so it happened between i last logged in and now. I'm trying to burn photos to a disc. what a pain in the ***! C'mon Apple! fix it! :) dang. I need this feature. ok. please update if a new answer or if someone gets it working!? -Barbee

I tried to edit my above. The above tells how to fix photo problem I didn't even know I had until I read it. It worked great to go to finder and photo's find what I wanted in a file and command click... THANK YOU!!!

Pictures are explained up higher by someone else. CD: make playlist, Put blank cd in disc burner, in playlist hover over the mixed album covers at the top (that is where it says burn to cd. Hope that helps.

I spoke with Apple Tech Support. There is an issue with blank discs in Superdrive running Mojave. Try highlighting the file you're trying to copy, go to File/Burn Disk. That might work for you. Not for me. They are aware and anticipate a fix in the near future.

What OS are you running, for starters?

Good that you contacted them. Hope they fix it soon.

Not sure why you replied to me.

I have same issue. You suggested work around thankfully worked for me. Thanks :)

Same issue here and the workaround did not work for me. Please update this thread whenever Apple has fixed this bug.

Thank you for posting this!
