I am pretty happy with my Macbook 2012 15 inch, I have put 16gb in with a 1tb SSD...
I am just wondering of the graphics card would be letting me down (you can't change it on these).
When editing in C1 the editing previews seem a little fuzzy, nothing I can't work with but still, I am a perfectionist and it just bugs me I am not getting the best I can get out of it, though admittedly I know a 21012 masc is hardly the epicentre of tech.
I switched from a 2011 Mac Mini (16gb) to a Mac Studio (32gb) in 2022, with the same Eizo monitor, and it didn't appear to make difference to the slight fuzziness. But I didn't make any direct comparisons.
At the time when the previews were really fuzzy, and there were a lots of people complaining, there were still far more people saying their previews were fine. On the occasions that they also cited their computer spec, the spec seemed to make no difference. People with maxed out specs seemed to be complaining just as much as those with low specs (like me).
From the limited information, posted over several years across different platforms and several interactions with C1 support, I never identified a solution. And it's difficult to know what people mean by a "little fuzzy". C1 said that the sharpness was "kept low", to facilitate speedy responses from edits, but it shouldn't appear fuzzy.
The only solution ever offered by C1, was to make sure the preview size matched the monitor resolution, but to make all critical edits at 100%. Other people (not C1) have suggested previews at one step down from your screen resolution and others one step up from your screen resolution, which worked for them - but not for me.
Nonetheless, I was still hoping for an improvement when I bought the Mac Studio, and didn't get one. So maybe it's something to do with the monitor, but C1 dismissed this as a possibility.
Although, I don't bother any more (so maybe it is a bit better than the Mac Mini) the solution that I suggested before ie to make an export recipe for a full size (sharpened) export to a TIF or PSD, and edit in soft proof mode for that recipe, resolves the sharpness issue. I used to flick between a soft proofing view and normal view, depending on how anoying I was finding the fuzziness.
Something that is different now a days, is that I now start in C1, but round trip to PS for some adjustments and then finalise the image back in C1. so the critical final adjustments are being made on top of a PSD, which is perfectly sharp.
But overall, I don't think an improved spec computer will "necessarily" resolve the fuzziness issue, but then again, it might :-(
Not a lot of help, but it's probably worth being aware of.
