OSX6 posted a topic in General DiscussionSo here I am, admitting to myself that I can't do this alone, posting on a forum for the first time. Hope someone can point me in the right direction. Ever since I upgraded to El Capitan (10.11) I have been plagued with this stage bug/glitch, in which every app downloaded form the App Store requires me to enter my Apple ID and Password to open said app on EVERY reboot. I'm usually greeted with this message when I try opening an app: "Insert app" was purchased using the App Store on another computer. To use "Insert app" on this computer, sign in using the Apple ID and password used to purchase it. Microsoft Office 2016, for example, doesn't remember my activation details and I have to re-enter them every time I reboot. I have had several hypotheses, NVRAM not saving (but iMessage works perfectly and values are retained), Broken Keychain (tried resetting it to no avail), etc. I also installed several OS X versions on my notebook to rule out possibilities. I found that none of the above happened on 10.9-10.10.5. But once I upgrade to 10.11 El Capitan, and the public beta of 10.12 Sierra, the same problem arises. So what could it be? New security features like rootless or something similar introduced since 10.11 and onward? Where could the problem be? It seems like every time I reboot it's a whole other computer. Seems like it since App Store apps and MS Office apps ask for activation. Im using Clover as my boot loader, r3642 to be precise. My notebook is an old Asus U50Vg, legacy BIOS.
