Apple Seeds Second OS X 10.11.4 El Capitan Beta to Developers

Please be VERY VERY careful when disabling system integrity protection, drivers that have not been optimized and or containing malicious code will not be filtered out by OSX and your machine will be vulnerable... Sorry for the Doomsday message, but fair warning needs to be given.

Out of curiosity, what would be your advice for people who don't use El Capitan and don't have SIP?

(I disabled SIP approximately 30 seconds after installing)

SIP is always the first thing I turn off on my 10.11 installs. I don't like not being in control.

This is usually an issue with the VPN client requiring an update, not a bug in the OS, per se.

My original post in the beta thread.

Seems like the bluetooth and 2.4 GHz wifi instability problems have reared their ugly head again :( also my USB 3.0 to Gigabit ethernet adaptor (using the Asix AX88179 chipset) is now non functional. The kext is not getting loaded on startup and OSX is complaining that it's unsigned, where as on 10.11.3 betas they were working and signature was in good order. I'm guess thats why everyone is having VPN issues because apple messed with kext signing.

Apple has changed the Kext Version signature and as a result Cisco needs to put out a revised lower level driver, if you need Cisco client as a mission critical app NOW you'll need to disable SIP (AKA kext signing\lowlevel driver protection) to get it to work. This method will work and is what I used to get my USB3 to Gigabit Ethernet Hub to work.

Apple is busy.

I'm curious if they'll add Night Shift down the line with 10.11.4 betas or wait till 10.12. Hopefully sooner rather than later considering how much easier it's been on my eyes at night using f.lux

I've been thinking the same thing. I have Flux but it'd be nice to have the two OS's stay consistent in that regard.

Well I'd say be aware of what lower level drivers you install on mission critical machines, be sure that any Kexts you use are from reliable sources. And confirm that said Kexts will not cause system instability because of device conflicts.

For instance I installed an older version of a USB3 to Gigabit Ethernet adapter Kext and it would cause my multi monitor setup to lose connectivity after waking from sleep because the Kext interfered with an AMD graphics Kext. kernal panics would also occur because of this incompablity.

Kext Signing was introduced into Mavericks but was easliy bypassed by using a boot flag Kext-dev-mode=1, why Apple changed it is probably due to security. That part of the post was mainly for people to be careful when changing low level security settings.

In all the years I use OS X, since the first beta of OS X (10.0b) I have never had any malware on any of my Macs, you are overreacting, OS X is one of the most secure Operating Systems, SIP is rubbish, I switched it of even faster than the person you replied to = less than 30 seconds.:p
Now, if we talk about windows-that's a complete different story.

Please Please reinstate the full screen "Places View" in Photos, like it was in iPhoto.

Someone else the same problems...? Wanted to install, but after reading this post I think I wait.

I've yet to have any major problems.

Even with the latest beta that was released today, don't go to this website [removed] I tried it and the website locks up Safari.

I got to ask...

1) why would you try this at all?
2) why list the website in this forum?

Apple is busy.

Thats why we give them so much money.
