Move your Photos library to save space on your Mac – Apple Support (UK)

It is indeed very much recommended to also backup your MacMini + your external drive with your photo’s .

Here’s how to use TimeMachine: Back up your Mac with Time Machine - Apple Support

When you buy a drive, it will be formatted for Windows. The first thing you need to do is erase the device using Disk Utility.

In Disk Utility, click the View button and select Show all devices from the popup menu.

Select the device name of the drive you attached.

Click the Erase tab and use GUID partition map and APFS format.

By default, external drives will appear on the Desktop and in the Sidebar. You can change that behavior in Finder Settings.

How are you handling your photo files? Are you just storing them in a folder in Finder or are you using Photos app?

Either way, once you move your photos to the external drive, you can remove them from the internal drive. If you are using Photos, you would move the entire PhotosLibrary to the external drive and then tell Photos to use that Library in the Settings.

If you've never used an external drive, I would imagine you also have never backed up your Mac. If that is the case, buy two drives, one for photos and one for a Time Machine backup. The Time Machine backup disk should be 3x the size of your internal disk + external photos disk.

A flash drive is not reliable storage. You should only store things on them for short-term functions like transferring from one device to another.

I recommend drives from OWC (MacSales.com) as they have proven reliability, excellent customer support and warranties. 

For your particular model contact OWC's customer support and get their recommendation for the SSD model that would best suit your iMac model, work requirements and budget. OWC is considered by most as the premier 3rd party hardware supplier for Macs.

Just wanted to ask you, would be more simple for me to just move these to a flash drive, then delete them out my Mack Mini M1 2020.

As I noted before, Flash storage is not a long-term solution. It is very unreliable. It sounds like you are trying to archive the photos with the intention of possibly using them again. Storing them on a flash drive will likely result in them being lost forever.

You should get a good quality hard disk drive or solid state drive. You will generally get more for your money with a hard disk drive, but prices on solid state have been coming down. And, if you really care about the photos and don't want to lose them, get another drive to back them up.

Try selecting the text, copying it and pasting into TextEdit or other text editor and then print from there.

OR use the Safari ➙ File ➙ Export as PDF menu option and save the entire thread as a PDF file. Or do a Print to PDF and try printing from the PDF file.

If you speed you want a Thunderbolt 3 NVM3 case with a pro NVME drive and replace it in future in case it dies for speed! if you want massive storage consider the smart NAS in Network for storing priture/videos for long term storage!
