15.2 & 15.2.1 fail to start on macOS

PostThu Dec 06, 2018 8:58 am

I succeed at running 15.1.2 with no issues. However, upon upgrading to DR 15.2 or 15.2.1, it simply does not start on 16GB RAM macOS 10.13.6 (High Sierra). I've never had an issue prior to this since 12.x. Could it be the DB? I've always opted to not upgrade/touch the DB. Where should I look in the log for clues? A cursory search only yielded the mention of refraining from upgrading to 15.2 due to stability issues. Once 15.2.1 was out, I thought it may have rectified any such issues.

Which Mac? Which GPU?

Both versions work fine here.

I'm on MacBook Pro 15" 2012 retina and never had a problem starting up.

I experienced the black frame issue as a bug in this version, but no beach balls, crashes, or startup problems.

Hope this helps to pin down the problem.

PS: Do you have Cuda enabled? I have turned off Cuda and enabled "OpenCL" This because there is NO valid cuda driver by NVidia for my MBP, so I turned it off.

I have a MacBook Pro (15-inch, Early 2011) with built-in AMD Radeon HD 6490M and Intel HD Graphics 3000. I'm not sure which graphics card DR is picking up, but I hope it's the Radeon.

I was looking at the Apple crash log, and I did see a mention of CUDA along with some dynamic libraries, which I thought was strange. Here's a snippet toward the bottom of the crash log:

Code: Select all

===========                     =======  =======
TOTAL                              1.4G      797


I also found the following to "force" the higher-performance GPU [URL not allowed] gfxCardStatus, and I then tried to start DR then with no success.

The CUDA System Preference pane that I downloaded after experiencing these issues doesn't help remove any CUDA references as well. Could DR be hardcoded to reference CUDA exclusively? I'll sift through the actual DR logs now since I found the howto page. I'll post back with more progress.

Go to the DVR preferences , tab "memory and GPU" and set it to "OpenCL"

But make sure your MBP supports it. A pre-retina MBP is really outdated for this powerful software. My 2012 MBP is already borderline outdates - I'm just waiting for the new Mac Pro to be released to upgrade.

Alas, DVR (DaVinci Resolve?) simply does not start, so I'm left with a lonely Apple crash dialog. I am however in:

and I see

Given this, it seems OpenCL is being used.

I think I've found the issue although I'm not sure where this leads from here. More investigation is needed. In the aforementioned directory, parsing through

I see:

================================
This application failed to start because it could not find or load the Qt platform plugin "cocoa".

Reinstalling the application may fix this problem.

The Cocoa API is quite vital to macOS, so now I'm going to attempt to satisfy this and determine why it happened. I have some guesses, but I'll refrain until I've exhausted some before I post back. Thanks for staying with me! ;)
