[QUOTE="Tom75, post: 1816111, member: 279482"] Thnaks guys for the valuable input, this idea with the external drive sounds good. mu external Thunderbolt 3 setup is a "Akitio Thunder3 Quad X" and I have several 4 TB drives in there which are empty and could be used for this purpose. Just a question to take this idea further, because I didnt know that I can simply install an OS and boot from an external drive: Do I actually need to install an OS on that external disk? I have not thought about that but could I simply connect the external drive to my old iMac with the damaged hard HD and, start it and just do a normal time machine restore to external drive Nr1. Or I could maybe even just install a recovery bootable version of an OS on that external drive? Anyway when I have done the timne machine restore or installation I can boot from this system and then when I am actually in there I can simply copy my pictures folder etc to the external drive Nr2. After that I dont basically need this system or recovery anymore, do I. So then I would be able to start up the new iMac with the migration assistant and I would not have to worry about the pictures folder since its already safe. I just want to be 100% sure when I do such that I dont mess up anything and I got now already very good ideas from you guys so I am sure it will work somehow, I just need to find out the best way. What do you think about the above idea? I also heard from a friend that the TimeMachine restore will detect the smaller drive and ask you which parts you want to restore to the new smaller drive? is that correct? Regards, Tom [/QUOTE]
