I understand that you want to set up SheepShaver on your newer Yosemite iMac.

1. As adespoton notes, SheepShaver will not run MacOS 9.2.2. It will run System 7.5.2 through MacOS 9.0.4.

I have been using SheepShaver under Yosemite, made the jump to High Sierra yesterday. Everything I try to do within SheepShaver's emulation works as before, as far as I can tell, but when I try to save or transfer files to "Unix", ...

I don't think it makes a difference whether the .cdr images are created in Disk Utility in Yosemite or El Capitan. The problem could be the format of these CDs. You can try to again create a .cdr image from a CD that worked before. If that image can be mounted in SheepShaver, ...

I am having a similar problem with Sierra.
