Tks RayIf you avoid music and video, and putting your image files on an external, you should have plenty of space. I run a 1tb rMBP. Take away image files only and I'm down to 160gb used. That's includes Lightroom, C1 and a smattering of small video files. Images catalogued are 40,000 with 2,880 preview sizes.
Tks PeterYou'll have lots of room if your photos are stored on an external drive. Your looking at about 4.5 GB for Lr & Ps. I've done the same and have 200 GB free on my rMBP with 256 GB of storage.
If flying, my only suggestion is to be very aware of weight limitations with carry-on luggage. I carry a lot of camera gear weight so have now opted for lots of memory cards and processing when I get home. Of course this may not work for your needs.

Tks, good point,No, 256 GB is not plenty. I've had a 13" MacBook Pro with 256 GB for ~2 years and then upgraded to one with 1 TB. With 256 GB I was constantly running out of space, even if I just kept some photos and some on there. All of this could have been mitigated by always carrying around an external drive, but what's the point of that? I'd recommend at least 512 GB.
Tks for the feedback,One of my MBP has 512 GB and right now the only software I installed was LR. I have about 23GB of Raw files with probably some of Apple stuff. If you shoot videos that number will add up quick. If you get a Mac with 512GB storage, you really are getting around 499GB. I haven't upgraded to the current OS. So possibly that number will be at least 2-3GB less.
Tks for the feedback,I make my living shooting and have a 250GB Samsung SSD in my MBP. I use multiple G Technology externals for RAW files, edited images and business documents plus another for Time Machine. I usually stay about 80GB used on the SSD and have never had a problem with it. I may step up to a 500GB drive when I replace the MBP but I don't think it's essential.
