I have an imac 10.9.5 running Mavericks. It has a failing hard drive. 1. I would like to copy calibre to an external hard drive so that I can transfer it back to the imac after the hd replacement. I still want to keep the backup on the hard drive. 2. After Christmas, I'll have a new ipad and will want to copy everything to the ipad, while retaining the information on the imac and the external hard drive. You can never have to many coping I suppose.
I did look through all the previous questions but never found a complete explanation for my gestalt impaired brain. Having all the mac explanations bundled together will certainly help. Thanks for any help you can offer. Feel free to answer just 1 or 2 if you find that easier.
