Mac Won't Download Application

We attempted to download Catalina from the Mac App Store but that time we were confronted by a message that the requested version of macOS couldn't be found.

Thank you for your prompt reply!

I read the link to the previous discussion thread that you suggested, and this is what I did that seems to have fixed my problem:

From nbar's recommendation I did:

Open Finder, from the menu bar Go.. > Go to Folder...

copy and paste the following path: ~/Library/Preferences/

Deleted the following item:

com.apple.appstore.plist

Mac Won't Open Any Apps

This item was not there:

com.apple.installer.plist

Then from Carolyn Samit's recommendation I did:

Mac Finder Won't Open

Open Finder, from the menu bar Go.. > Go to Folder...

copy and paste the following path: ~/Library/Caches/

Deleted the following folder:

com.apple.appstore

So actually, thank you to all three of you!

Safari User Guide

Safari can download most types of files, but if you have trouble with a file, try these suggestions.

Mac App Update Won't Finish

• If Safari is still downloading the file, wait for it to finish. You can’t open a file while it’s being downloaded.

• If the download is paused, resume it. Show the downloads list by clicking the Show Downloads button , then click the Resume button for the paused download.

• If you see a message that the app can’t be opened because it’s from an unidentified developer or wasn’t downloaded from the Mac App Store, you can open the app by overriding the settings in Security & Privacy preferences.

• Sometimes a download is incomplete because the file was damaged. Try downloading it again.

• Make sure you have the app needed to open the file. If you do, the file may have been corrupted during the download. Delete it, then try downloading it again.

• The downloaded file may be a compressed archive or disk image that contains the file you want. If the file is from a trusted site, double-click it to decompress it.
