Sounds like a boring and dumb plan, but I'm on COVID protocol and bored and Ive been watching Halt and Catch Fire and feeling nostalgic, so I am going to build all my main photo and music libraries in Tiger. That's why I needed the new HD. First stage is complete WD 500 Blue booting 10.4.11 perfectly. Stage 2 will be to export all photos out of a Catalina photos library for use in iPhoto 08 and iTunes 9.2.1. I have 2 main libraries that I maintain in iTunes, a 120GB and a 560GB, the 120 is the core library of can't live withouts like Floyd and Leppelin and Lana. Stage 3 will be admiring my modern digital life inside my favorite OS of all time on a 16 year old laptop that feels as fast as my M1 running Tiger. I love me some Intel Tiger...
