Help needed to set-up Seagate SSD external drive.
All going ok till I met the attached brick wall. What do I do next please?
I was setting it up by entering TM on my Mac and trying to add it. I only got to the screenshot I have attached.
The previous screen said: Disc usage limit. Then gave me 2 opions: None and Custom. Guessed both times but both took me to Couldn't unmount disc, so neither None or Custom worked/used.
Should I erase all the data to use my new device for TM machine backups only?
I can see the my new device in Disc Utility and it is mounted. Surely it needs to be mounted.
So confusing. Please advise.
PS. my imac is 2023 and used Sequoia.
