cura 2.7 will not run on Mac OS X 10.8.5

[RoboDLC 1]

A fresh install of cura 2.7 will not start on Mac OS X 10.8.5 running on a Core2 Duo MacBook.

When I open the app, nothing happens, no error no startup screen nothing.

Is there something that I'm missing?

Thanks,

DLC

There is nothing here:

$User/Library/Application Support/cura//cura.log (OSX). So I tried running it on the command line and got the trace:

Any clues here?

Pff, not really. It seems to crash when trying to acces a function from a support library that we use.

Did you also have issues with previous versions?

Nope.  I have only run cura on my PC up until now.  My only laptop, for traveling demos is my Mac.  Cura 2.7 is the first version I have tried to install on it.

Edit #1:

I just tried cura 2.6.2 - Same thing happens.

One more detail in both cases:

Initially the "C" appears on the dash board as the OS verifies the install, then it warns me that this is the first time it has run an internet download of cura.  when I give the the "OK" it crashes silently, no error screen, no log file.  Every attempt to start it past that point is a silent crash.

Edit #2:

Cura 2.6.2 will open and run if I open the app container, go to MacOS and double click on "cura". A terminal window opens and tons of info and a few errors are thrown out. Then cura actually starts and asks me to define a printer.

Cura 2.7 will NOT work if I go this path, I get a similar error as I posted above in its terminal window.

Hopefully something I am saying helps.  Does no one else out there have this problem?

Thanks,

DLC

I will uninstall for now. Maybe a later version will work. Or, maybe not so much on a Mac.

Thanks all

I have just downloaded Cura 2.7.0 onto my iMac running El Capitan (10.11.6) It would not run as has been mentioned in previous posts...

I renamed 'Cura' to 'Cura 2' in the Applications folder and, voila, everything starts as it should.

Don't know why but it's working so I'm delighted.

Cheers,

Dave

Consider upgrading the Mac to 10.12, the current release.

Cura 2.7 and previous run fine on my iMac, aside from criminally slow launching.

I had the same issue on a MacBook Pro running OS X 10.12.6.

Tried 2.7 and 2.6.2 with no luck.

Then copied them to my apps folder and renamed them Cura2.7 and Cura 2.6.2 and both worked.

Go figure?

I have OS X 10.8.5.

I have installed python and some libraries just to code with.

This is the error I get trying to install the latest Cura

Your macOS is too old to run the latest Cura version. Minimum requirement is 

• Mac OSX 10.11 or higher, 64 bit

 

And 10.11 is also sometimes too old (some users reported problems). 

 

So update to a newer macOS (currently we have 10.14.2, so your 10.8.5 is really old) or use an older version of Cura.
