For about 10 years I use the CD ripper (R15) on the iMac under macOS10.6.8 with BootCamp and Windows XP.
I use the external CD drives PLEXTOR PX-W 1210A and Yamaha CRW-F1.

Last week I installed the version R16.6 MAC on a new iMac with the following result:

1. When the CD Drive is open, the drive is no longer recognized. Only when the CD is inserted manually, the drive is recognized.

2. The Eject button can no longer be used to close the drawer.

3. Under Windows XP I could adjust the ripping speed. The ripping speed is no longer adjustable. The drive is fixed at maximum.

What do I have to do to be able to set the ripping speed?
