UPDATE: Issue resolved. Thanks to everyone who responded for their assistance. There appears to be a "lag" in the App Store between the installer being deleted from my MBP SSD and the App Store recognizing the installer was deleted. The link on the App Store now says "Download" instead of "Open." Again, Thanks to all for the kind assistance. I searched for the answer but couldn't find it so here goes .... I downloaded the Mojave 10.14.0 installer, created a bootable flash drive, clean installed Mojave on an external SSD so I could "try it out" before installing it on my production MBP. After creating the bootable flash drive I deleted the installer from my Applications folder and emptied the trash bin, so there should be no remnant of the installer on my MBP. I'd like to update my bootable flash drive to Mojave 10.14.2, but the App Store link shows "Open" instead of "Download." Any suggestions on how I can locate and download the updated Mojave installer? Thanks.
