When I try to connect the Apple SuperDrive or an external DVD drive and try to read a CD-ROM, I can see the drive in Disk Utility but the drive won't mount the disc. It gives the error, "Could not mount "name of disc". (com.apple.DiskManagement.disenter error 49153.)
I have content on this CD that I would like to preserve. It is a problem that the drives won't mount so I can access the disc in Finder.
MacBook Pro 15", macOS 10.15
I have the same problem with the error com.apple.DiskManagement.disenter error 49153
i ran first aid to an external drive that has been working flawlessly for the past 3 years just to see if There are any errors or if there are issues I need to fix. I regretted this right away as after running first aid (and the machine saying there’s nothing wrong with the external drive) that drive wouldn’t mount no matter what I do. Similar issues as others, greyed out, repair and other first aid options work but won’t mount on my desktop or laptop computers. Of course Apple techs says it’s the machine’s fault that it decided to clonk out at that very exact moment I ran first aid. This is an 8Tb drive and many years’ worth of work. The only reason I’m not freaking out is I have a cloud service (not apple’s!) provider that sent me a copy of that drive. Best investment in my life. But c’mon Apple, don’t undermine my intelligence by saying it is the fault of the drive.
It would have been helpful for Apple to have posted a warning along with the Catalina upgrade/downgrade, allowing those of us with important data archived on HFS disks to copy it to other media beforehand.
I'm getting the same error (com.apple.DiskManagement.disenter error 49153) using a brand new Apple SuperDrive as well as on generic external DVD Drive (also new) when trying to mount old CD-R disks. These mount without problems on an old MacBook with an internal reader as well as on a recent MacBook Pro with these external drives. The only difference I can see is that the MacBook Pro is still running Mojave and the problem occurs on an iMac Retina 5K (late 2014) with Catalina (up-to-date). Note that this occurs only with old CD-Rs that I burned on a Mac (Mac OS Standard file system); I'm able to mount CD-Rs that are not Mac formatted with both drives.
I keep getting com.apple.DiskManagement.disenter error 49153
none of my external drivers working anymore.
APPLE, please fix it.
The exact same driver with same format, works on another laptop. Also ran on catalina.
The problem seems only appear in MacBookPro (15-inch, 2018).
With upgrading to macOS Catalina Version 10.15.2, my SuperDrive will now read Movie DVDs and play movies. It will also read Music CDs and allow them to be played and viewed in Apple Music. However, I still get the same error message when I try to mount a CD-ROM disc. This feels like a security issue with Catalina. We need Apple to fix this.
I actually found a workaround but not sure it will work on your guys. In my case, I have to log off the account and re-log in. ( note, even restart isn’t working for me, it must log off. I knew it is wired so I’m not sure it will work with others)
Where is Apple Support when we need them? So many people having this error message. I upgraded my OS to Catalina only last week and my Mac Superdrive which has always worked no longer appears in finder, and when I try to mount using disk utility I also get the error message: com.apple.DiskManagement.disenter error 49153.
Not good enough Apple! Where are you?
I finally got Apple to fix this issue on my Mac Pro (Late 2013) after I upgrade to Catalina. Under Finder, Preferences, General tab, make sure "CDs, DVDs, and iPods," is checked. Guess it defaulted unchecked when I upgraded.
Digging deeper, it turns out that I can mount CD-Rs formatted as "Mac OS Extended" (HFS+) and all the ones that will not mount are formatted as "Mac OS Standard" (HFS). Looks like Catalina has dropped support for old HFS volumes, bummer if you have a bunch of old CD-Rs.
I have the same issue with the same error code(com.apple.DiskManagement.disenter error 49153.). Even DVDs from Photodisc in Mac OS standard are not mounting. Could this be a preferences issue?
MacBook Pro (Retina, 15-inch, Late 2013) 2.3 GHz Quad-Core Intel Core i7
I have the same problem, I can mount music and movies, but I can't mount an old English/French dictionary on CD-ROM. I've just upgraded to Catalina 10.15.3 beta, but the problem persists. I get the same (com.apple.DiskManagement.disenter error 49153) message.
I've just used the Feedback Assistant to notify Apple of the problem.
Having the same issue. I have MacPro (early 2013, trash can). Upgraded to Catalina and now my SuperDrive not recognized. Also have a new MacBook Pro running Catalina and won't work. Have and older MacBookPro (2013), running High Sierra and it works. So clearly this is an Apple OS issue AND NEEDS TO BE FIXED! Where is the Apple fix people? Called Apple to trouble shoot. Reseting RAM and other steps did not work. Had to send diagnostics and await an answer in three days! Agent admits there's an issue and sometimes it's correctable . . . but not with me. GEEZ! All my photo libraries from 15 plus years no longer accessible.
I was same problem. In my case helped open disk in another laptop (Macbook Air with Catalina). On first laptop error again but on second laptop opening correctly. I was insert disk again to mine macbook after this operation and it worked correctly.
I was having the same problem. I could see the drive in Disk Utility, but the drive wouldn't mount the drive. I noticed that when I physically disconnected the drive, the drive continued to appear in the drive list in the Disk Utility. I rebooted my machine and the disk was able to mount.
If you open Activity Monitor, search for "fsck" then force quit it, it allows the disk to mount as read-only. Then you can transfer the files onto another hard drive, re-format the original disk and you're good to go.
