Earlier today, I needed to reformat my external HD, so I erased all contents (which included ESO).  Now, however, upon attempting to reinstall ESO, I'm unable to do so.  I keep getting this message:
“'setup' can’t be opened because Apple cannot check it for malicious software. Software needs to be updated. Contact the developer for more information."
Can ESO still be installed on a 2017 MacBook Pro?  If so, is there a way to update the software so that it runs properly?
