Psystar already owes Apple $75,000, documents from the former's bankruptcy proceedings indicate. Psystar recently submitted a filing mentioning Schedule F debts, those to creditors with "unsecured nonpriority claims." Though Apple is on the F list, it is unknown what the money may be owed for. The only other explicit information from the filing is the phrase "litigation pending" under the section citing Psystar's consideration for the claim.

Although Apple and Psystar have been engaged in a bitter a legal dispute surrounding Mac clones, no final judgments have been made, which may make it unlikely that Psystar owes its challenger legal fees. It is thought that the company may instead owe Apple for copies of Mac OS X Leopard, which in many cases were bought directly from Apple. $75,000 could translate into several hundred copies of Leopard at the $129 retail price.

The resolution of lawsuits is on hold until bankruptcy proceedings complete, or a judge rules otherwise.
