I was prompted to update Native Access on my iMac last night. I obeyed. Then when I restarted the computer and relaunched it, did the signing in bit, it got stuck at a dialog box that just had the logo in it and Release 3.4.0. End of story. It wouldn't go any further.
I then tried all the manual uninstall and reinstall afresh advice, pasted the bit of code into Terminal, gave NI apps access to whole drive, yadda yadda... still the same. I've lost count of how many times I've typed my login in, restarted the computer et al. Bored now. And life's too short for this bobbins. I've submitted a support ticket, but was wondering if anyone else was having the same issue?
