What type of files are you going to edit, RAW I would assume.
I used to have a 60D and my current MBP always was able to efficiently process without delays. I just changed to a 6D with larger files and I can see it struggle (as I may get the multicolor disk when downloading and such) at times.
My MBP has the following specs:
15.5" retina screen (2880 x 1800)
i7 Intel processor @ 2GHZ
8GB RAM
Graphics Iris Pro 1.5
250 GB SSD
SD card slot (nice, as my cameras use this type of card and it makes it much faster to download than using the USB connector from the camera)
What would I do different? as much RAM as I could afford, as much processor as I could afford (at this point, a faster i7) and at least twice the capacity in HD. Many people keep their raws in external HD which is fine, except that takes away your portability. Now, let's be honest, a 1TB external HD is a rather small item nowadays, so that shouldn't be a big issue either. They way I work is by keeping my raws in the laptop and then copy them to an external drive every quarter and deleting such files. Before that, I do backups in time machine anyways.
I have used prescription glasses since I was 9 (I'm currently 46) so I prefer the larger screens. Some people are comfortable with an 11" screen, but to me, that doesn't cut it. But that ends up being your own preference. Keep in mind it's a portable item. You could always get an external monitor for a more comfortable view at home.
You pay a higher premium for an Apple, but you get upgrades in all the software contained with your equipment for as long as the hardware can support the upgrades. If you mainly use it for photography and web surfing then a Mac is a wonderful choice. If you have other requirements, you have to consider those as well. Windows or IOS generates such controversy, that it could very well be added to the list of trouble-topics that we all know and avoid (sex, religion, politics).
Oh and as far as software goes, Lr for everything and sometimes Ps.
I hope this helps, this is what works for me, always keep in mind what you need and evaluate it from the perspective of what would work for you.
