1. Hello,

My MacBook is not allowing me to access my extensions,

I tried:

On your Mac, select a file, then choose File > Get Info, or press Command-I.

2. Click the triangle next to Name & Extension to expand the section.

3. To show or hide the filename extension, select or deselect “Hide extension.”

and also tried

In the Finder

on your Mac, choose Finder > Preferences, then click Advanced.

2. Select or deselect “Show all filename extensions.”

If you select “Show all filename extensions,” all extensions are shown, even for files that have “Hide extension” selected. If you deselect “Show all filename extensions,” then file extensions are shown or hidden based on their individual “Hide extension” setting

neither worked,

Are you saying across the board that file type extensions are not showing for any file type?

If this is a corrupt plist you can —

corrupt plist, delete the com.apple.finder.plist
