Brand new iMac & Adobe lR Issue

[ItalianBoston]

Hey All. I just got a brand new 2017 5K iMac. Specs are: i7 4.2, 40 gigs of ram, 1tb ssd.

I am running adobe lightroom and when editing photos LR is sooo slow! Anyone else having an issue like this? Anyone know why?

Didn't think my brand new $3k computer would be this slow when editing photos.

I have iMac Pro and latest LR is painfully slow, I confirm.

What version are you both running?

And what cameras? I have a late 2014 5k iMac (i7, 32gb, SSD) and LR (CC) ran OK (not great, but not troublesomely slow) when I was using a D810 (14 bit RAW). Then I moved to a D850 and it's just awful -- the iMac, I mean.

I don't know what to do -- I was wondering how a new iMac would work, so as not to have to go for an iMac Pro.

So you guys -- what cameras?

I'm using LR 7.3.1, and I don't think its related to LR speed but I have Sony RX1R-ii camera

I'm using the latest version of LR and my camera is a Nikon D810. I am seriously thinking of switching to a different photo editor. Anyone have a recommendation?

It seems that the issue here is LR not being compatible and not the iMacs?

I'm surprised (and unhappy) at both of your reports. As I said, LR (latest CC) D810 RAW images aren't unmanageable on my old iMac -- things are a little pokey but not off the charts. But the D850 -- ouch, forget it.

I have a DxO Photo Lab but I don't use it much. I'll spend some time with it this week. I think there's a reasonable free trial for it.

I was thinking about picking up a D850, think I'll hold off until I find an editor that can handle the big files.

Anyone use Affinity Photo? Looks pretty good.
