Skype for business crashing on startup in Mac 10.11.6 since June
Hi, Since one automatic update was installed (I know, my mistake for having the automatic updates on), I cannot use Skype for Business for Mac anymore. My OSX version is 10.11.6 El Capitan and I cannot upgrade it because of hardware limitations. I tried the instructions in the following URL with no luck: https://docs.microsoft.com/en-us/SkypeForBusiness/troubleshoot/server-install-or-uninstall/clean-uninstallation I tried the following versions with no luck: 16.27.35 16.27.36 16.27.37 (this one with the installer filename 16.27.0.37) 16.28.72 16.28.98 As you see, there's "normal" and office insider versions. I'm pretty desperate 😉 The only version I was able to successfully use since June is the one I downloaded long time ago: 16.17.0.65 I know later versions should also work because I remember a nice version with animated emojis, probably the 16.26.19? I saw mentions to that version around internet, but I couldn't find it for download. All pages refer to the Microsoft download link, but the file is not available in that location at all. Any ideas? Alternatively, does anybody know the way to get an older version of Skype for Business? Thanks! PS: Here is the stack for the crashed thread upon start. If I'm not wrong all the tested versions show the same error (EXC_BAD_INSTRUCTION): Process: Skype for Business [1126] Path: /Applications/Skype for Business.app/Contents/MacOS/Skype for Business Identifier: com.microsoft.SkypeForBusiness Version: 16.28.98 (16.28.98) Code Type: X86-64 (Native) Parent Process: ???
