OpenGL replacement for OS X Mojave

Apple has deprecated Open GL for all OS versions beginning with 10.14. It is dead slow on my MacBook Pro running Mojave. Unusable. 
Is there any chance that a different rendering framework can be used?

    Preferably not. Supporting metal will effectively double the amount of support required for all 3D rendering. So even though the move from Apple is understandable, it's a complete nightmare for developers that support multiple operating systems.

    I am a Mac only user and have no problems with the performance. Ok, it is not the fastest application, but it is as slow (of fast) as ever. I had not problems with Majave and also not with the current Catalina.

     

    I run Cura on a MacBook Pro 15 (2018), a MacBook Pro 13 (2018) and an iMac, all with the same performance.

     

    But if Apple has deprecated OpenGL, I'm worried about what will be with Cura in future versions of MacOS. I hope the developers will find a solution for that.S witch to Windows or use Windows is a VM is a no go for me 🙂

    Deprecating is of course not removing it all together. As long as they keep openGL in there, we will do our best to keep it working. But if they were to actually remove it and there is no alternative that works on all operating systems, i fear the worst. It make take us months of dedicated work to port it.

    Or linux... Can actually linux boot an a mac computer? (never had a mac...). Is Cura compatible with linux?

    Just noticed when I clicked on send that my post actually has nothing to do with the topic, sorry.... But I am to interested in the answer to delete my message 😛

    Is there a way to check what renderer Cura is currently using? A Radeon 560X with 4 gigs of vram should be able to handle the task with no problems.

    Could you say what version of Cura you are using? Also, please go to Help -> Show configuration folder and locate the file cura.log that should be in the folder that opens. If you could upload that file and post a link here, I can see what is going on with the renderer.

    Perhaps porting Cura to Vulkan is a possibility as that is supported by all platforms.

    Given the number of questions why the layer view does not show a play button, there are still a fair number of users with hardware that does not even support OpenGL 4.1, let alone Vulkan.

    Sorry it took me a while. Here's a dump:

    Your Cura is using hardware-backed OpenGL rendering:

      • UltiMaker Cura 5.3 stable released
        In this stable release, Cura 5.3 achieves yet another huge leap forward in 3D printing thanks to material interlocking! As well as introducing an expanded recommended print settings menu and lots of print quality improvements. Not to mention, a whole bunch of new printer profiles for non-UltiMaker printers!

      • Here it is. The new UltiMaker S7
        The UltiMaker S7 is built on the success of the UltiMaker S5 and its design decisions were heavily based on feedback from customers.
         
         
        So what’s new?
        The obvious change is the S7’s height. It now includes an integrated Air Manager. This filters the exhaust air of every print and also improves build temperature stability. To further enclose the build chamber the S7 only has one magnetically latched door.
         
        The build stack has also been completely redesigned. A PEI-coated flexible steel build plate makes a big difference to productivity. Not only do you not need tools to pop a printed part off. But we also don’t recommend using or adhesion structures for UltiMaker materials (except PC, because...it’s PC). Along with that, 4 pins and 25 magnets make it easy to replace the flex plate perfectly – even with one hand.
         
        The re-engineered print head has an inductive sensor which reduces noise when probing the build plate. This effectively makes it much harder to not achieve a perfect first layer, improving overall print success. We also reversed the front fan direction (fewer plastic hairs, less maintenance), made the print core door magnets stronger, and add a sensor that helps avoid flooding.
         

         
        The UltiMaker S7 also includes quality of life improvements:
        Reliable bed tilt compensation (no more thumbscrews) 2.4 and 5 GHz Wi-Fi A 1080p camera (mounted higher for a better view) Compatibility with 280+ Marketplace materials Compatibility with S5 project files (no reslicing needed) And a whole lot more  
        Curious to see the S7 in action?
        We’re hosting a free tech demo on February 7.
        It will be live and you can ask any questions to our CTO, Miguel Calvo.

      • UltiMaker Cura Alpha 🎄 Tree Support Spotlight 🎄
        Are you a fan of tree support, but dislike the removal process and the amount of filament it uses? Then we would like to invite you to try this special release of UltiMaker Cura. Brought to you by our special community contributor @thomasrahm
         
        We generated a special version of Cura 5.2 called 5.3.0 Alpha + Xmas. The only changes we introduced compared to UltiMaker Cura 5.2.1 are those which are needed for the new supports. So keep in mind, this is not a sneak peek for Cura 5.3 (there are some really cool new features coming up) but a spotlight release highlighting this new version of tree supports.
