I recently upgraded my 15 inch 2018 MacBook Pro which has 32 GB of RAM and a 2.6 GHz 6-Core i7 processor. I use the laptop mainly with Adobe Lightroom and Photoshop. I don’t do anything more taxing. I bought a 16 inch MacBook Pro M1 Max with 64 GB of RAM.
I noticed a major speed improvement right away. I have one large Lightroom Catalogue with many collections and smart collections. On the 2018 MacBook Pro, the smart collections have been slow to load. On the new machine they are sometimes instantaneous and sometimes very quick. The difference is dramatic. Editing in Lightroom is quick and responsive. Photoshop handles large files quickly and easily.
The screen is amazing. I see detail I did not see before. Some photos that I thought were in focus now seem slightly out of focus. The dynamic range is wonderful. This is the best screen I have ever seen.The keyboard is very nice. The built in speakers are louder than I expected on a laptop. It’s early days but so far I love the new M1 Max. Apple really delivered.
