Clone problems

[1974darrenh]

I'm normally a “Windows" man but someone has given me an iMAC Retina 5K 27 inch 2017, running Ventura 13.7.8

Im trying to upgrade it to an SSD but all the clone processes fail.

Firstly I used “Disk Utility" which fails and shows a “OSStatus error 49157.

I then tried “Carbon Copy" which I thought was working, but when I tested the new SSD, it wasn't showing in the startup disks so I couldn't select it to boot from.

Has anyone got some advice or recommendations of other software I could try? As I said, I'm a newbie when it comes to MacOS stuff.

Thanks in advance.

Does the iMac boot to Ventura now?
Can you get logged in to an account and be in the finder?

Tell us about the SSD.
Is this an external SSD?
If so, does it connect via USB or thunderbolt?
Or... is it an internally-installed SSD?

Tip for erasing the SSD:
If it won't erase to Mac format, then...
...Try erasing to a "PC format" first.
Try exFAT. Does that erase it?

Once you've done that, do THIS:
Now erase it "back to" a Mac format.
Use APFS, GUID partition format, and BE SURE that it's "case INsensitive".
DON'T use "case sensitive".

Does that work?

If so, then try CCC.

BETTER SUGGESTION:
Since you're a PC person (perhaps not well-versed in Mac?), I'll offer another app to try:
SuperDuper.
SD is FREE to use for the job you need.
It's also one of the easiest-to-understand and use apps out there.

You can get it here:

SuperDuper!

Let us know how you make out.

It boots to Ventura and I can log in (only on the installed hd, not the new SSD)

The SSD is external. My intention is to clone the old drive to the new SSD then install that in the iMac as the main bootable drive.



Thanks. I'll try your tips and get back to you.
