and add a space at the end. Then drag and drop the file MacTeX.pkg to the Terminal window to complete the command. Push Return.
- openssl md5
The Mac will compute an "MD5 checksum". The correct sum is shown at the top of the downloading page here.
Change the word md5 to sha256 or sha512 in the previous command to check the Sha256 and Sha512 sums, also shown on the linked page above.
What to do if the Checksum is bad
Many users report trouble after downloading with Google Chrome,
and possibly other browsers. We strongly recommend downloading with
Safari. Users with problems also report success after downloading
via the torrent network.
