Drive not found in Make MKV

Post by jens123 » Thu Nov 15, 2018 2:17 pm

Hi,

I used a LG external BD drive on my MacBook Pro for some time without any problems. Now after two month without use the drive isn't found by Make MKV. In OS X the drive and the disc is found without problems.

This week I did a clean set up of the MacBook and directly testet if the drive is found by Make MKV. This was successfull. But after installing all the software I usually use now the drive is not dectected from Make MKV anymore. I didn't use other software than before.

Does anyone have the same problem or anyone a solution how to solve this problem? I really don't know which of the software could be the problem.

Did you restart the computer after installing all the software?

The usual issue is that some software (sometimes the operating system itself!) takes control over the drive, and it no longer gets reported as an optical device when MakeMKV asks.

Sometimes unplugging the drive and plugging it back into the computer resolves this problem. I've had this myself last night and this solved it

I know this is an old(er) thread, however I have recently started to have this same issue with my MBP

I get the following error in MakeMKV
MakeMKV v1.14.3 darwin(x64-release) started
The program can't find any usable optical drives.

however in System Profile I see the following
