How to start an extra external hard disk as a working disk on my Mac mini?

My MacMini has a 250 GB ssd Disk.

When working using Photoshop and Bridge lately

it starts saying that there is no space enough on the disc.

So now i bought a 2T Samsung ssd external drive

to solve the problem.

What do I have to do to make this work?

Look through the Adobe documentation for Photoshop and Bridge. There are ways to move some of caches and libraries to an external drive which can consume large amounts of space.


Also, you can additionally move your music and video libraries to an external drive.


These days for anything more than just simple email, web browsing, and streaming, 256GB drives are pretty anemic and doing anything else than that really needs a minimum 512GB drive.

Aside of the ''how to'', and while the 2T should be a good solution, perhaps longer term you should consider a foldable USB4 M.2 SSD enclosure and have the option to swipe in M.2 PCIe Gen4x4 SSD (look like memory card). I run Final Cut and Davinci projects all from this now, and it's really snappy. This way, 2TB are now affordable, but later you can use 4TB or more as prices eventually come down (depending on tariffs I guess...). You can get these on Amazon (enclosure: mine is from CAbleMatters) and my NQ790 is from Lexar. (Just make sure the combination chosen works.
