MAC STORAGE IS ALLMOST FULL WANTS TO MOVE PHOTOS TO EXTERNAL HARD DRIVE

It’s easy to do: prepare the external hard disk: format it in MacOs Extended (journaled) or APFS if it’s a SSD (a SSD is faster). Use Disk Utility to do it. Once done, drag your photolibrary to the eternal disk. Test it and if it works allright, you can remove the library from your internal disk. For more info: https://support.apple.com/en-us/HT201517
