Now if I could actually get a link to download v5.2.5 r869 I would try it. Currently the client I have a link for is ps-pulse-mac-5.2r4.1-b787-installer.dmg and that one crashes (this is the one PulseSecure send out via email when you request to download the client).
I went back to 5.0.3 r44983 at the moment since that is working for me.
@EntropyWorks: are you able to login to the support site (my.pulsesecure.net) to download the latest client? Or you may be able to ask your IT team, or if you are evaluating the software, work with your account team to obtain the 5.2R5 client
