This does appear to be stable in OS X 10.9 - thanks for the heads-up. For the driver, does 'restart having the device disconnected' mean 'restart *with* the device disconnected? Steve

I too have experienced instability with Waveforms on an older version of OS X – everything beyond 3.6 crashes here in launch. I see that the new Waveforms 3.9.1 comes with an optional driver ''For OS X 10.13 or earlier version'. Is this intended to fix the instabilities discussed in this thread, or is it for some other purpose? (I'm still on OS X 10.9 for a variety of reasons that have nothing to do with Waveforms.)

I understand. At least WF 3.6.8 works here. At some point soon I will actually get a physical Analog Discovery 2 (the relevant project's been on the back-burner for 18 months), which will allow me to test whether this is anything to do with running WF in demo mode. At present though it's looking as if more recent versions of WF aren't compatible with OS X 10.9 ('Mavericks'). (I'm stuck with Mavericks for reasons of not rocking the boat with more mission-critical stuff, like all my costly Adobe software that runs under an OS X 10.6 virtual machine in Parallels, plus FrameMaker under Windows 7, ditto.)

Ah, right - sorry.

Sorry, don't understand what you mean by 'insight'.

I'm sorry it's taken me a long time to get back to this. WF 3.7.19 also exhibits the same crash on launch behavior here. I've appended the initial section of the crash dump below. It's maybe important to note that I'm only running WF in demo mode. The highest revision that is stable here is 3.6.8. Waveforms 3.7.19 crash dump.rtf

The Digilent website states that Waveforms v 3.7.5 works with OS X 10.9. However, it always crashes on launch here. v 3.6.8 works just fine.

Thanks!

I've got more info. I think at least part of the problem occurs at save-on-quit: when a cmd-Q or File->Quit command is issued, at least one instrument window closes before the context save. That instrument is therefore not saved, and so not re-displayed on open. Steve

If I spot any causative factor that makes the issue repeatable I will let you know. Steve

I ought to add that this problem is intermittent, so not necessarily repeatable. I've not found a set of circumstances that precipitates it. Steve

Is this issue being addressed? I am definitely seeing lost instruments on a context save/restore, and I need to make a purchase decision. It might be specific to my setup: 2013 MacPro/Mavericks (OS X 10.9.5) with a simulated Analog Discovery 2 in Waveforms 2015 v 3.2.6. I appreciate that you are working on Waveforms 2016, but if there is a bug, I don't expect you want to carry it over into the new version. I'm entirely happy to run tests and/or diagnostics here if that would help: I'm excited about the Discovery 2 and am happy to help. I spent half my working life on electronics of one sort or another, so generally know what I'm doing. Thanks. Steve (BSc MBCS MISTC CITP)

Ignore the screenshot, which was done with 3.1 - I am now definitely using 3.2.6. I tried to attach a screenshot of the 'About' box to prove this, but I get a message saying I'm only allowed to upload 30 kB. The missing instruments aren't opening outside the screen area, as they don't show up in the Window menu either. Steve

It might be this issue only shows up when the workspace is saved as separate windows. Steve

Right - it's happened again, definitely with Version 3.2.6 for Mac. With multiple instruments open, including a scope, waveform generator, pattern generator, logic analyzer and static I/O, only the scope and waveform generator were reopened after save and restore. There are definitely some bugs here, perhaps in combination with changing the window type from tabbed to separate. Steve
