had to force shutdown WOD..now it it SO HOT and wont complete a start up.It is a MacBook pro
well i dont know anything about what macbook you have, but if it is one you can easily open up. go ahead and replace the thermal paste with arctic silver 5.
Even if this is a machine that's relatively easy to open that's not something I'd recommend first thing without knowing more information. If the Mac shut itself down that might indicate there is actually a heat issue. If the owner forced shutdown because they thought the machine was overheating when it actually wasn't that's a much different issue.
@ OP I can understand how one might have thought the system was overheating. My MacBook Pro generally runs in the neighborhood of 170 degrees fahrenheit. During some recent video conversions it ran at 200+ for most of a day. Don't know what the temps were that night. It certainly felt hot but never had an issue.
a macbook should never run hot enough that you can significantly feel how hot it is.
