Mac OS X Lion installation stuck on "Loading Installation Information"
The clock may have been reset. Setting the clock may resolve this problem.

Enter recovery mode.
Select Utilites in the menu bar.
Open the Terminal.
Type: date {month}{day}{hour}{minute}{year}, e.g. date 0804221520 for August 4 2020, 22:15.
Try running the installation again. It should now proceed in less than a minute.

If this does not help, showing the &quot;Istaller logs&quot; may provide hints why it takes too long.
