In July I downloaded the public beta for El Capitan. Everything seemed to go well and I had no problems until after I downloaded public beta 4. After that I was seeing problems like safari closing randomly. Apps closing or opening without being prompted. Today I restored my macbook air to factory and restored with time machine so far everything seems to be behaving normally. ButI still can't download iTunes 12.2.2.I got the prompt for the update last week and as you can see in the image I've provided it shows it was installed when in fact it was not as you can see 2 other versions saying it was installed yet it keeps showing up in the App store to update which I am doing as I type this. It will reach a certain point and the App store will suddenly close. Well today I was prompted by the App store that OS X public beta 5 was available for download and again it would start to update when then App store will suddenly close.When updating any App I usually start the update and walk away not wanting to use up bandwidth so I can have a faster download. I did a diagnostic on my route and it seems to reworking fine. Anyone else having this problem. I hate not knowing what's causing this and my OCD is rearing it's ugly head. Help before I lose my mine.
