Hello Lee.guirado,
I understand that you're having trouble with the installation of several apps on your Mac. In order to isolate and resolve an issue like this, the information outlined below (and in the rest of the article linked, as well) can help restore proper functionality to your Mac.
If you're seeing unexpected behavior on your Mac try these steps first:
Try searching Apple's knowledge base for the specific symptom or alert message you're seeing. There might be simpler steps you can take to resolve the issue.
Try starting your Mac in Safe Mode. Restart your computer. Hold the Shift key when you hear the startup sound. Release the Shift key when you see the Apple logo appear. This starts your Mac in Safe Mode. Safe mode performs a directory check of your startup disk, and removes some cache data. After your Mac finishes starting up, restart your Mac normally (without holding the Shift key) and see if the issue is resolved.
Make sure your software is up to date. The issue you're seeing might be addressed by installing available updates.
Check to see where the issue happens. If an issue appears before you see your desktop, it's less likely that it's related to a user account or setting. If an issue happens with a website, see if pages from other websites load correctly first. There might be an issue with the site and not your Mac.
How to test an issue in another user account on your Mac
