Hello. I'm planning on moving from one mac to another one. The old mac will be erased and given away. I want to put all of my files onto an external hard drive (for preservation) and from that total backup, select individual files to put on my new computer. Basically, I want to save all of my files on the external hard drive, but only put some on the new computer. My biggest fear is forgetting to put a portion of the files on the external hard drive and losing them forever. Thus, I'm wondering if time machine can be trusted to back up every single file onto my external hard drive? Furthermore, I want to know if from that time machine back up I can drag individual files on my new computer. Thank you.
