Kindly add the customary "RESOLVED" to the title of your thread for the benefit of all readers.mac_in_tosh ? TomH TX :
Thank you both for your input. Was finally able to successfully install the update! Followed a tip received from MacInWin (Jake) at MacForums. Booted while holding down the option key and choosing Internal drive from the options list.
I'm guessing the security update you are referring to on this thread is 2019-002?
I currently have 2019-001 but have not gotten any update notification for 002 on the app store.
Sorry, I don’t know why you haven’t received the notice yet!Any ideas why I did not get a notice for 2019-002 security update? Thanks.
This update is again showing up as available in the App Store. I thought I just did it ???
I experienced the same thing yesterday after installing the downloadable version.
The "RESOLVED" should be added to the title of your thread, not inside it in a post. That shows readers the problem is no longer one.RESOLVED with much thanks!
