Installing and running macOS on external SSD to replace HDD from 2017 iMac
Hi,
I am looking to install an external SSD on my older iMac (2017) to replace the existing HDD for running MacOS (Ventura 13.7.8). My current HDD is running slow and I have been advised that installing an external SSD instead can speed things up.
My question is what format to use for formatting the SSD in order to make it work with the existing HDD?
Any help is appreciated. Thanks
iMac 21.5″ 4K, macOS 13.7
