Version 16.0 Update

This is the first time anyone has reported this. I wonder if there is something about the particular design you are trying to save. Could you send me the BCAD file in question and let me know what kind of change you are attempting to make?

The only other thing I can think to mention is that double clicking on a BCAD file will not open that particular design. You have to either choose File >> Open design from BCAD file or drag and drop the file into the main BikeCAD window.

As far as I am aware, everyone impacted by this has been able to resolve the issue by uninstalling older versions first. Another option would be to run the 32 bit version. Let me know how you get along.

Thanks for letting me know about this. I have not been able to replicate this issue at my end. There were not meant to be any changes related to this in moving to version 16.0. Your dialog box dimensions and locations are stored in a file called: dialogs1.xml. This file should be found in the folder called: BikeCAD_16.0_configuration. As this file does not seem to be doing anything for you, you could delete it. BikeCAD will create another file next time you open and close the program. I wonder if, since your dialog box information is not being stored, there might be any other things that are not being stored. For example, are you able to go to View >> Customize >> Save current bike as default template? Doing that should save the model that you are currently viewing so that it will appear as the default design when you launch BikeCAD. I wonder if BikeCAD might not have permission to write to your BikeCAD_16.0_configuration directory. This is why I'm curious to know what other customization options can be implemented.

I believe you may be the sixth person reporting issues with Mac OS 11.0.1. Many of these users have also had trouble with other software since upgrading to this version of Big Sur. As far as I can tell, the issue is beyond my control. However, I believe the problem might have been resolved with the latest Mac OS which as of December 14, 2020 is 11.1.

I'd be curious to hear from other Mac users about their experiences.

I'm sorry to hear you went through all that and still have no luck.

First thing to be aware of is that your license of BikeCAD entitles you to install the program on up to three of your own computers, so if you have access to another computer, that could be one solution.

While I assume the issue is related to these latest Mac updates that will hopefully be resolved in a future update, it is strange, because I know of some other users that are running BikeCAD on Mac OS 11.1 without issue. You said you uninstalled BikeCAD before re-installing it. When running BikeCAD for the first time, a directory called BikeCAD_16.0_configuration will be created to store customization data. When you uninstall BikeCAD, this directory doesn't necessarily get deleted as well. In case the problem has to do with some sort of corrupt configuration file, it could be worth deleting this directory. I would not worry about uninstalling BikeCAD again. You've already tried that, and this is a separate possible cause. If you delete the BikeCAD_16.0_configuration folder and then try to launch BikeCAD, BikeCAD should look for the configuration directory. If it does not find it, it should extract a new folder. It would be nice if once the new folder is extracted BikeCAD works as normal.

A final possibliity could be to install the Java Runtime Environment (JRE) on your machine and then run the Linux version of BikeCAD which should run on any computer that is running the Java JRE.

I'm sorry I have no definite solution for you, but I hope this can get resolved soon.

Have you updated from Mac OS 11.0.1 to Mac OS 11.1? I believe the issue may be confined to Mac OS 11.0.1.

Installing the Java Runtime Environment on your system and running the Linux version of BikeCAD would remain an option to try. However, another thing to consider with this BikeCAD_16.0_configuration folder is the possibility that after deleting the configuration folder your system is not fully extracting all the files that are meant to go into the new version of the BikeCAD_16.0_configuration folder. To thoroughly investigate this possibility, I've uploaded the contents of this folder to: https://www.bikecad.ca/myConf.zip . Could you download this file and try extracting its contents in place of what you have there now? Before you launch BikeCAD are there any glaring differences between the folder automatically extracted and the one you've downloaded?

Sorry to hear that didn't help either. Those two extra files are created by BikeCAD to store the directory of the most recently opened or saved design as well as a list of most recently opened designs. So I don't think we've found our issue yet.

To continue to dwell on this configuration folder might seem like beating a dead horse, but there's another thing to check. What if after launching BikeCAD, you choose the Primary dimensions icon instead of the Wheels icon? When the Wheels dialog box is launched, BikeCAD must check the BikeCAD_16.0_configuration/WHEELS folder to find any Standard wheels. When you launch the Primary dimensions  dialog box, it does not need to check the configuration directory for anything. I'd be curious to see if you can change things in the Primary dimensions dialog box without issue. If you can, there could be some problem with permissions in the configuration folder.

While I don't think running BikeCAD on Mac OS Big Sur is a problem for most users, I'm at a loss to suggest any other possible fixes for your particular situation. The one remaining option, and I think it's a good one, is to install the Java Runtime Environment on your Mac and run the Linux version of BikeCAD through that. The Linux version should really be called the universal version because it can run on any OS that has the JRE installed on it.
