iMac 27" 2017 not booting after blade upgrade
Hi out there, please help me: I put a new blade into my iMac 27 2017 letting the old 2TB HD of the fusion drive stay. Now I can choose whatever volume I want but boot process stops after 20 sec and I get this sign (see att.). I hope somebody can help me. All the best for 2021 for all of you
