I am considering buying the Q2, but I'm worried the file sizes will be too big for my 3-year-old MacBook Pro with only 16GB of RAM.  I use the subscription based Photoshop for processing because I am used to it.  Should I worry about the Q2 images slowing down the computer to a crawl or locking it up?  Please advise.

Should work, I've done some Q2 and SL2 DNGs on my 2012 Macbook Pro 16GB, 1TB SSD and external 6TB drive and CC2020 without problems. I'm sure higher specced computers will be faster, but this was quite adequate.

Jim, I use a 2017 MacBook Pro with 8 GB of memory for on-location processing.  I've processed Nikon D810 36.3 mp files with Photoshop 2020 and Phase One IQ4 150mp files with Capture One 20 and, converted to .tif, with Photoshop 2020.  You will not have any trouble with a Q2 47.3 mp.  Just make sure you have a big enough disk, either internal or external.

I think this concern is unwarranted. I’ve processed Q2 DNG’s on a pretty new MacBook Air, a 10 year old iMac and now a 2019 iMac. The latter is the fastest mostly because my library resides on an external G-Drive with USB-C I/O. I don’t find any of the solutions particularly challenging. The 10 year old iMac struggles because the I/O is USB 2.0. Slow. Good luck, but I don’t think it’ll be a big problem. As in all applications with photos more RAM is always better.

If you send me your email via PM, I‘ll send you one or two DNG-files shot with my Q2. Then you can check yourself if it works good enough for you. 
Cheers, Thomas.

Not sure about Mac, but i run either Lightroom or now Capture One with Libreries of thousands of photos.
Lightroom uses more memory than CaptureOne, now i have 14GB of 32GB of RAM full, with Lightroom it was some GB's more.
I have usually at least 2 browsers open, email progamm and some other stuff.
As long you don't have also Photoshop and Illustrator open your MacBook should work fine for fiel operations.
At home you may want to have a recent Imac with 32GB RAM, SSD and a fast processor/video card.

I haven't run into any editing speed challenges with Lightroom on a 2018 iPad Pro. (Not even a Mac.) It's pretty snappy, in fact.

Also note that you can (and should) compress the DNGs once you get them on your Mac. You can do that with the free Adobe DNG converter, or with a Lightroom hack post-import. I really wish Adobe would allow compression on import, and on the iPad, but it's better than nothing.

The DNG compression is lossless, by the way. You don't lose any information, and it takes the 85MB files down to 40-60MB, depending on content.

@JimD -

I am using a 2013 MacBook Pro with 16GB of RAM and 500GB of storage and it is running just fine.  I  am using Lightroom for post processing and storing my RAW files on a 2TB external hard drive with a second 2TB external drive for a backup.

I have not had my Q2 long enough to amass a large library of the 47MP RAW files, but I do currently have just short of 92,000 RAW files made with my M 240 and M-P 240 which are 24MP in size.

Many thanks to each of you for your helpful comments.  It's reassuring to know that the Q2 file sizes are not going to be a problem for my laptop.  I have an M-9, an M-10 and the original Q.  I must say that there's something about the M-10 that makes it my favorite, but I do think I will go ahead and also add the Q2 to my kit.  The Q2's extra resolution for enlargements is very appealing.  Regards, JimD

These "later" macs have the Ram soldered on the main board, you can not change that. 

The photos of Q2 are less than 100MB so there should be no issue there. Even if you are running heavy apps, most of the time you have GB's free. And if it comes close to being "full", the mac will buffer on the main disk, which is "flash" memory, so the buffering is almost at the light of speed...
