Hello experts !
Every time this error appears when I want to install some programs downloaded from the Internet. Sometimes it appears and sometimes not. Any solution for this error ? Why I cannot open all the programs to install them ?
Thank you !
“New App” can’t be opened because it is from an unidentified developer.
Your security preferences allow installation of only apps from the Mac App Store and identified developers.
