External hard drive not recognised by MacBook 2020

I've just bought a new MacBook 2020 for my son and a Seagate external hard drive for back ups. I've just plugged in the hard drive for the first time and it doesn't show up in the Finder or in the Disk Utility. The device lit up when I plugged it in, so there's power and I can see it on the System Report in About This Mac. How do I get the Time Machine to recognise it?

MAC not connecting to external drive? An external hard drive that I had been using to hold backups for my MacBook Pro does not show up in the Finder sidebar when I connect it to my new MacBook Air. It also does not appear in the list of available disks to select in Time Machine. I've ensured that Hard Drives is selected under Finder Preferences. The device does appear in the USB list under System Information. How can I get Time Machine to recognize this drive?

Time Machine USB Hard Drive (Seagate GoFlex) Not Accessible on M2 MacBook Air Hi Folks, I recently upgraded my aging Intel MacBook Pro to lovely new M2 MacBook Pro. While most aspects of the migration has gone well, something that has not gone well is using my Time Machine drive on the new laptop. The drive is a Seagate GoFlex. My problem is that this hard drive is completely inaccessible on the new laptop. By this I mean: The drive does not appear in the Finder The drive does not appear in Disk Utility The drive does not appear in the Terminal diskutil list command I am able to connect other external hard drives. I am also able to connect this hard drive to a Dell laptop running Windows 11 and I can see it in the Disk Management app, although it cannot read it since I'm pretty sure it is formatted as APFS. I'm largely sure this issue is due either to MacOS Ventura, or using Apple Silicon, as the drive was working fine with the old Intel MacBook Pro that was running MacOS Big Sur. Has anyone else encountered a similar issue that they were able to fix? If not and no other options are available, does anyone know how I can at least reformat the drive so I can continue to use it? It looks like I should be able to format the drive using the Dell but that surely can't be the only solution, can it? Cheers in advance for any suggestions.

Hi,

If a USB device doesn't work with Mac.

If it doesn't help, try resetting SMC which could solve the issue.
