Hi
I have a 2017 iMac 21.5 inch. The hard drive is getting slower and slower with beach balling and taking a long time to open apps, etc. I have bought a Lacie 1TB external hard drive and formatted it, but I am unable to transfer data from Time Machine to this SSD. I want to use the external drive as my start-up disk.
Any advice would be appreciated.

Format the external SSD, Install macOS on the SSD, startup from the SSD, migrate from the Internal drive or Time Machine.
Use an external SSD as your startup disk … - Apple Community
Migration Assistant is the app that does the transfer for you.
Many thanks, that worked.
