Nice find! I’m jealous!! 
Let’s try this again. Here is another build that should at least fix the python path issue (hopefully) http://devel.alephobjects.com/software/cura/packages/test/Cura-17.10-MacOS.dmg
Latest build (17.10-MacOS) runs well under 10.10.5 on both the MBA and MBP. Many thanks to hemocaynin and amcdawes who have more familiarity (and time) to dig into the code than I (and of course the AO Crew, - Nick, Steven/MC, Orias and the others in the background).
I just completed a 2 hour +, 95% Rocktopus (100% just a tad to large) to go along with my original 80% version in HIPS (Jet from Amazon), using “my” standard settings:
240 HE
100 Bed
2.85mm
90.0 flow
All Other Settings Unchanged (Cura Mini HIPS Medium Profile)
Preheat bed to 80 (just to speed things up) while heating HE to 250
Extrude 20mm to insure no issues, hit print & pre-wipe with 3M medium pad
Final pre-wipe when the HE has cooled to ~162 and away it goes!
Thanks again to all,
Chazz
I had been using my printer extensively the last few days and so didn’t install this newer version till just now. I deleted that python link I made, and it loaded up just fine. 
On Windows, if you switch Machines through the top menu bar, the options on the left disappear. You need to then resize the window manually to make them show up again
Having that dual hex v2 selection available is just cruel.
Is there a place we can make suggestions for the software?
One thing I’d love to see is dual dimensioning in Cura. While I freely admit that metric is far superior to imperial dimensions, I still think in inches/pounds/etc. If something is 2" I can picture that immediately - if I see 67 mm, it takes a second or two to figure out roughly how long that is and it usually involves converting it over to inches.
In the CAD world, dual dimensions are usually handled something like this:
1 in [25.4 mm]
Its just a thought. I am not even sure if this is the place to post something like this, but it would be helpful in the software.
I miss being able to extrude smaller amounts than 10mm.
I also wish the nozzle temp and bed temp would not reset to 0 when a print is canceled. I can see it being reset if control is exited, but if I cancel a print to fine tune the z stop or bed level, I often press print before realizing the temps have been turned off and I am way under temp to print. Then I have to do another cancel and reset the temps and wait for them to heat up, and then purge the filament to get past the notch ground in by the hobbed bolt before I can print again.
The only other issue is, every once in a while, after going into control mode, the tabs for basic, advanced, plugins, and start/end gcode disappear, and I have to restart Cura. I’ll pay more attention next time to better describe what condition leads to this issue.
Otherwise, it’s operating well
kaldyn, what version of Windows are you using?

Hazdaz, the best place for making suggestions is code.alephobjects.com or more specifically: https://code.alephobjects.com/maniphest/task/create/?projects=Cura . There is some discussion on adding in imperial measurements at some point in the future.
saramos, what situations would you use <10mm extrusions? What were you trying to accomplish in those situations? Thanks for the other feedback too.
I use the manual extrude to ‘prime’ the nozzle before a print. I suppose I could just add a start gcode to do this, but the amount needed varies based on what’s previously been done on the printer (first print, restart, second print). I just got used to doing it with the manual controls under ver 15. I would do 1mm extrudes until ABS started coming out the nozzle. Then I’d start the print.

I do the exact same thing.
