OS 10.11.4 broke all of my applications...

I just updated my Macbook Pro and my Mac Pro to OS 10.11.4. On my laptop, everything seems to be fine. On my Mac Pro, none of my applications

will open. I get an error that says "You can't open the application "Disk Utility" because it may be damaged or incomplete." I get the same message on all the applications I try to open. I am beyond p i s s e d. There is absolutely NO excuse for this kind of thing to be happening in this day and age. If anyone know WHY this d a m n update did this and what I can do to correct it, your input is greatly appreciated. Thanks in advance.

Mac Pro, OS X El Capitan (10.11.4), 24 GB, Radeon 4870, Blu-ray

Similar problem here. I updated to 10.11.4 and Safari is completely hosed, uses 99% of cpu, so I closed it and went to Chrome. Something is badly wrong with this update.

On a whim I tried the 10.11.4 update from the App Store and lo and behold everything seems to be working properly, Applications and Utilities in place and working. As I said in my previous post I felt as if the update (from the combo updater) seemed to go quickly, but I wasn't watching very closely, but I think that it didn't do a complete job with the install. I noticed with the App Store update the installation part of the the update process seemed to take quite a bit longer.

WW,


Consider creating a separate partition on your mac and install 10.11.4 on this partition, then install each third party application one at time on the new partition assuming everything remains stable noting which app if any causes instability. Finally copy your personal data to the new partition and test for a few weeks if no issues have occurred. If everything functions and remains stable after that test period you could delete your old partition and then expand the new "test" partition to fill the entire volume.


just an idea...

P.S. Running factory supplied fusion drive here on my Retina 5K, 27-inch, Late 2014 with zero issues with the .4 upgrade or a clean install.

For any that may be confused...

...this post refers to the full installer of 10.11.4 which would be required for installation on a new test partition on an existing OS X 10.11.x, etc machine if not clear.

If I remember correctly this is the first time since 1986 that an OS update gave me problems. So, once every 30 odd years is not bad statistics. Still, I found no resolution to the problem. I even erased my disk, restored from a bootable backup, but now the updater downloads, installs, but at the end of the process I am left with 10.11.3 - This is amazing.


This is why I was looking for the full installer so that I can install on a clean empty disk and then use the merge with an "older" mac - an option that I remember that was once available.


Thanks anyhow,

Shuka
