External HD for MAC

I have some portable external hard drive available and want to be able to use them for Mac, both for transfer files and back up. At the moment, it can be read by my iMac but not read, what format do I need to format the HD to? And what is the easiest way to do it?

Format the drive to exFAT, HFS, or APFS in disk utility.

I don't recommend FAT32.

Thanks, do you mean format it in a Mac or a PC, you mean disk utility in Mac, you mean the one you need to restart to enter?

Press Command+Space bar then start typing Disk Utility.

You'll be able to format it from there.

You can open Disk Utility from a Finder window.

Thanks, I can format the drive, but I am trying to partition it in disk utility so I can use part of the disk for Time machine backup, but the "partition" button is grey and I cannot select it in disk utility? Any solution for that

Thanks all, problem resolved, it was just sth. that I have to click "view" to change to "view all devices" first to be able to erase all the drive rather than the original single volumn.
