RUMLogNG problems on OS X 10.11

[NA4M]

After upgrading to OS X 10.11 RUMlogNG began to hang/crash on my system. I've happily run RUMLog and RUMLogNG on previous OS X versions with no noticeable problems.

But under 10.11 recent RUMlogNG versions (v 2+) hang/crash frequently. Typically RUMlogNG will run ok for some time then hang/crash with the spinning beach ball and the OS X Activity Manager shows RUMLogNG "not responding" and I have to do a force quit. After that 1st force quit RUMLogNG will not restart - the RUMlogNG icon unhappily bounces up and down in my tool bar. I have to force quit it again. Then my system has to be restarted/rebooted before RUMLogNG will restart normally.

Anyone else experiencing similar issues under 10.11?

Do you use CAT? When yes, which chipset is used? Could be a driver problem, some important changes were made in 10.11.

[NA4M]

Yes - I run CAT with my K3 and P3. I assume you are asking about USB-RS232 CAT cable chipset? I am not sure of chipset but I think it may be Prolific PL-2303

When I added P3 (before OS X 10.11) to my station my Elecraft KUSB cable would not work with my K3/P3 CAT combination. My KUSB would function only with K3 CAT alone.

I replaced KUSB with a USB-RS232 adapter cable from local electronics store. It worked OK. But perhaps it's not OK with 10.11?

My KUSB did not work with K3/P3 CAT before 10.11 but maybe it will work with 10.11 ??

What do you suggest Tom?

I'm going to install the latest driver I can find for the PL-2303 chipset and see if that helps.

The Prolific will cause trouble. You can check it in the System Profiler under the USB section, when the cable is connected. There is a walk around to use a Prolific under 10.11, you should search for it in the web.
If you have a FTDI chip, make sure you use the latest driver from the FTDI site b

Thanks Tom.

I found a new v1.6 certificate signed OS X driver dated 10-22-2015 on Prolific's web site.
------------
Revision Change:
====================
v1.6.0: Add code sign certificate to driver for Mac OS X security requirement. Only supports Mac OSX 10.9, 10.10, 10.11.

I've installed this new driver and so far OK and hopefully this will resolve my problems - but will need a few days to be sure it doesn't repeat the previous hangs/crashes.

I'll add info here of results after several days running.

Tnx

As of today I've had no more RumLogNG hangs/crashes since installing the latest version of the Prolific chipset drivers mentioned above.

Tnx to Tom for pointing me in the right direction!
