Since my Windows laptop died on me recently I've been reviewing the Apple iMac 21.5 inch with retina 4k display, to edit my 25mb RAW images.
However, after some research earlier today I'm not so sure. One forum's members were very critical about the time images take to load from LR.
The last thing I want to do is spend a wad of money on something I regret.
Thanks for any comments.
The iMac will be fine, get a SSD, maximum RAM and a fast processor in the options.
Geoff has provided you good suggestion.
Also, please click on below link for the system requirements for Lightroom.
Also, please make sure that the graphics card is supported.
Hope this helps.
