Is there a solution to the verification race condition on mac?

[bunk3m]

Very strange story similar to tanjao and Michael re "Installing on iMac".

I used 2.6.9-1 on my MBP about 10 days ago without problem.

I noticed in the list the release of 2.6.11-1 so I downloaded it today 
and installed it as I always do. (drag and drop the app & files into 
Applications).

I opened Gnucash and got the verification window which never goes way. 
My MBP fans start screaming.  So I start up htop and I see a process 
starting to using 200-300% of the processor and eating up more and more 
memory.  When I killed the Gnucash app, it was approaching 8GB RAM and 
15GB Virtual memory.

So I deleted 2.6.11-1 and reinstalled 2.6.9-1.  Unfortunately 2.6.9-1 
now has the same behaviour.

I restarted the MBP and tried to start 2.6.9-1 again hoping I could 
complete some accounting entries and the race condition starts all over 
again.

I'm on a 2015 MBP; OS 10.10.5; Quad i7.

I noticed this issue has been outlined by a couple of people so was 
wondering if there is a solution?

Thanks in advance.
