PSD files are generally associated with Adobe Photoshop, and therefore require the program to open and edit them. However, there are a number of ways to open, view and even edit PSD files without having to use Photoshop, particularly on a Mac. Here are a few methods:
GIMP
GIMP is a fairly well-known photo editing program that is available for free online. It can be downloaded here: https://www.org/. While GIMP cannot natively open PSD files, there is a free plugin that can be downloaded here: https://www.uk/blog/how-to-open-psd-files-in-gimp/ Once installed, this plugin enables GIMP to open PSD files just like Photoshop would.
Inkscape
Inkscape is another free program that can be used to open and edit PSD files, and can be downloaded here: https://inkscape.4/. Inkscape also requires a plugin to enable it to open PSD files, which can be downloaded here: http://blogography.com/archives/2011/08/15/photoshop_psd_templates_for_inkscape_vector_graphics. This plugin will enable Inkscape to open PSD files in the same way that Photoshop does.
These are just a few of the programs that can be used to open, view and even edit PSD files without using Photoshop. There are many others available, both for free and for purchase, so there is sure to be one that meets your needs and budget.
So there you have it – a few methods for opening, viewing and editing PSD files without using Photoshop on a Mac! Give one of these programs a try next time you need to work with a PSD file and see how it goes!
