Fusion 360 update fails with macOS 10.15.3 Catalina - OpenSSL?

[dave.kingma]

The auto update feature of Fusion 360 is not working on my Mac running macOS Catalina v10.15.3. A copy of a portion of the autodesk.webdeploy.streamer.log file is included below. It seems there is a problem with the SSL. I checked the native SSL versions on my machine, although it looks like Autodesk runs Python3.5 from their directory structure, so I'm not sure if it's relevant. However, if I enter "python" on the console, I see that the version is 2.7.16 and it is running LibreSSL 2.8.3. If I enter "python3" on the console, I see that the version is 3.6.0 and it is running OpenSSL 1.0.2j 26 Sep 2016. I've seen other posts regarding old versions of Python with Autodesk, but I'm not sure this applies here. I am reluctant to uninstall Fusion 360 and try and install again, mainly because I'm afraid that I will get the same SSL error and will not be able to download the application. My current version of Fusion 360 is 2.0.6258.

I am seeing the very same behaviour

The same error occurs with Mojave Mac OS V 10.14.9  (My Mac note book)

For the team at Autodesk - Fusion, are you able to provide some feedback here please? I have seen some previous posts and discussion re the open SSL issue that date back to the beginning of 2019. At tht time it seemed as if a solution was some time away and as far as I can tell it was not resolved?

Am I now doomed to remain at my current version of F360 without the benefit of addiditve manufacturing etc?

[Anonymous]

Well, I ran out of patience and went the brute force route - removed and restored F360 - I now have the latest version of F360 - remains to be seen if the next update will download properly, fingers crossed.

However the chsnge of licence type issue remains. I now have start up licence - again! Despite the fact that the AD web site states that this will not happen! No doubt I will get a terse email telling me to change licences again soon.

[dave.kingma]

That is encouraging. What process did you use to remove Fusion 360? Some of the posts say if you don't remove all remnants of the program, you'll have problems installing again. I went to the location of the log file and found a handful of directories with long alphanumeric names, and found a couple of Fusion 360 executables within those directories with different version numbers - 2.0.6026 and 2.0.6258. My docked icon pointed to an alias just above those directories. There were two of the alphanumeric named directories that had just Helpers directories or 0 byte applications. Should I get rid of all the directories and start fresh? Or is there an uninstaller? I couldn't find one.

Thanks,

Dave

You can find the instructions for an auto clean and a manual clean here 

I did the manual clean on my i mac and an auto clean on my notebook. Both methods worked fine. BTW, after the reinstall, the licence update process has finally worked as well. (on my notebook at least, with check the i mac tomorrow)

Good luck!

[dave.kingma]

Thanks! Yes, I did the manual clean and re-installed with no issues other than there was a directory Autodesk said to delete that was not there; however, there was one that was closely named. I didn't delete that directory and it didn't affect the re-install.  Back up and running!
