I have a 27¡± late 2015 iMac running High Sierra. (I just bought a 2019 MacBook Pro running Catalina FWIW)
Just the other day, my iMac told me I "didn¡¯t have the necessary permission¡± to make changes with my HDD,
and several other inconveniences.
The HDD is the most important, of course. But I am the only person to use this computer, so I do not need
this level of security.
I read about problems with Preview, so I dragged Preview onto the desktop, and rebooted. I also took
Preview out of Container (I forget the proper name, but I did it correctly), rebooted, and that didn¡¯t help.
I went through several pages of advise to help.
The closest advise seem to lie within terminal.
I like this idea because while this latest denial of permission happened just the other day, I have had trouble
moving things to the trash, and several other things like that should not be a problem.
(I also used Disk Utility from an external hard drive to run Disk Repair).
So, I would like to have this latest problem resolved, along with the lesser permission problems.
Also, I am experiencing the same problem with my MBP.
I am NOT a guru. I treat Terminal with respect. I have used it in the past, and will again.
I do not want to back up my iMac, as I am afraid i would duplicate this problem.
I am sure I have omitted necessary information. So, just ask.
Thanks,
Doug
