I need to buy a Mac laptop for multi-shot capture, but not proccessing, only capture.
Is a MacBook Air i5, 8Gb RAM enough for Phocus and MS capture?
If not, what's my minimum requirement?
Many thanks.

I don't use laptops when shooting so my recommendations may be suspect.
You need a Mac with a dedicated, discrete GPU to run Phocus. That means a MacBook Pro i7 with a dual graphics setup, as far as I can gather. My brief search showed me that nearly every MacBook has an integrated graphics unit which I do not believe works well with Phocus.

From experience, one can certainly run Phocus on a Macbook air. The dedicated processor is not absolutely necessary, especially if only capture is intended and no post-processing.
What I do not know is whether multishot is possible on these machines. I don't have a multishot back.
Thanks for the replies.
A few queries elsewhere have suggested that the MacBook Pro would be necessary for MS capture.
A new range of Mac laptops is imminent. That might change things.
In the meantime, I think Hasselblad could be more specific about requirements, making a decision easier, don't you?
Thanks again.

Some processing must be done in the background when capturing 4-shot images. My old backs take five exposures (black calibration + 4-shot) but produce one MS image.
Hasselblad's GPU recommendation may only be needed for on-screen viewing.
You may need to call Hasselblad tech support for a definitive answer.
From the Hasselblad website, downloads, Phocus 3.0.4 Read Me PDF:
Graphics adapters-
You should be aware that the Phocus viewer utilizes the processing power of the GPU - therefore using a Mac with a high performance GPU is definitely an advantage. All current Mac's using discrete GPU's should give good performance, we do not recommend using a Mac that only incorporates an integrated Intel GPU.
Chris,
Many thanks for the clarification.
So, which if any of the laptops here would satisfy Hasselblad's GPU criteria?

Since this is just for capture, I want to spend as little as possible and refurbished is good enough for me.
Thanks again.

Quite frankly, I doubt that the requirements are that high for capture only. They date back to a time where integrated graphic coprocessors were a lot less powerful than today. As I said: I use focus on a macbook air just fine, although some post processing operations are indeed a bit slow. The only difference is that I do not have a multishot back.
Can't you just borrow a macbook air to test how it really is?

I wish... :)
Thanks for the reply.

Where do you live?
Have had a reply from Hasselblad saying that, for capture purposes, MacBook Air is ok with my 39 MS and Phocus.

All's Well That Ends Well.
Denis,
Good, now you have a recommendation from on high...
I shoot in client's factories or showrooms and I bring lighting so I have access to electrical power. I use iMacs for tethering when "out in the field".
While I have not looked at MacBooks for several years, I did not like the change I saw in brightness and contrast (and maybe a change in color also—it has been several years since I looked) as I changed my viewing position when looking at the MacBook display.
Happily, I found iMac displays very tolerant of off-axis viewing. I can have three or four people gathered in front of my 21.5 inch iMac and no one is seeing an odd looking image. (I find 21.5 inch iMacs easier [lighter] to take on location and more stable when put on the lightweight folding table I bring with me on location.)
