Can't load once installed using new macbook w/Yosemite just shows "Verifying"

edit

Same problem reported here:
https://ask.libreoffice.org/en/questi...

As I described in more detail there, LibreOffice 5.1.5 ran for me after 15 minutes of verifying. (OSX 10.10)

Had the same problem as others where Verifying would never finish (5.1, 5.0 versions). I'm on Mavericks. Presumably it's a bug in the verifier, which runs in a process CoreServicesUIAgent. If this process is not killed (e.g. in Activity Monitor, or Terminal) then it will consume all RAM and kill the machine. I let it run to this point once before I realized it was fatal. Maybe this bug is fixed in newer OS?

Turning off Security for apps (From Anywhere) eventually worked, but I had to fiddle around as well.

Same problem with Mavericks on an early 2008 iMac with 4GB RAM. Two attempts to verify failed each time, crashing OS X, which simply froze up.

Downloaded LO 5.1 again and re-installed. Only started Firefox/Thunderbird alongside LO to minimise load on system. Verification took 20 minutes but eventually worked, just as I was about to give up hope.

Turning off gatekeeper is a workaround, not a solution. I have also the same problem with LO 5.1.0.3, but not with 5.0.5. It does finish the verification, but it takes a very long time. See https://ask.libreoffice.org/en/questi...

Probably to do with gatekeeper, as explained here: https://www.libreoffice.org/get-help/...
