How about
function highlight_text($text, $highlight) {
return preg_replace('/(' . $highlight . ')/i', '<span
class="highlight">$1</span>', $text);
}
Case should be retained and the search is case insensitive

That's not where the issue is.
Eregi_replace conducts a case insensitive SEARCH but how the REPLACE
operates has nothing to do with it.
If you use ereg_replace, then it is most obviously not going to replace
"MacOS" with "<span class=highlight>macos</span>" or even "<span
class=highlight>MacOS</span>", because the string searched for is of a
different case.
But thanks for helping.

You're using the eregi_replace function - which does case insensitive
replaces (read the man page).
Change it to use
ereg_replace
