There is a way to do something close - it involves adding a bookmarklet to Safari and selecting that once you're on the page.
However, this will either open only the hyperlinks you've selected (i.e. highlighted) on the page or it will open all hyperlinks found on the page if you haven't highlighted any. In other words, it doesn't work in the Command + click manner you want.
If you're interested, here's the process to set this up:
- Visit any page using Safari
- Press CommandD to add a bookmark to the page you just visited
- In the highlighted field that appears in the window, change the text to something like Open all hyperlinks
- Press OptionCommandB to edit bookmarks
- Find the bookmark you just added and right-click on it
- Select Edit Address... from the context menu
- This should highlight the URL. Press Delete to remove it
- Now paste the following code where the URL was previously:
- Press Return to accept the code
To make this work, open any page in Safari and then select the bookmarklet. One of the following things will happen:
- if you haven't highlighted any hyperlinks on the page, the code will proceed to open all hyperlinks in a separate tab
- if you've highlighted x number of hyperlinks, then the code will proceed to open those selected hyperlinks in separate tabs
