since upgrading to LR 4.1 it keeps constantly freezing up on me and I have to restart my computer. Anyone else having similar issues? New iMac

If it's that new you need to make sure the memory and mainboard are sound. An app cannot freeze your computer by itself. This is a hardware or OS problem.

Software cannot cause a system to freeze.

You most likely have a hardware problem or a bad low level driver.
The most common causes are bad RAM, bad video cards, bad CPUs, bad motherboards and bad power supplies.

Well maybe, but it wasn't doing this before 4.1. and it's a brand new iMac. I know it could be a lemon, but it seems like a lot of people are having similar issues with LR4...

I am on the phone with Apple and they disagree. They say that absolutely software can cause the entire system to lock up. Of course it's hard for me to tell because I don't run much other software on this computer but it's never locked up on me in anything except LR or PSE. Since the updates.

The person you are talking to has absolutely no idea what they are talking about. A software or hardware engineer will tell you that only hardware faults or very low level drivers (part of the OS) can cause a whole machine lockup or reboot.

Photoshop and similar applications stress the hardware more than most -- by moving and processing a lot of data very quickly. This exposes problems with RAM, CPUs, motherboards and sometimes power supplies that most other applications will never encounter. Slow software won't stress the hardware as much, and won't always show the same problems.

And no, other people are not seeing their entire system freeze with Lightroom or Photoshop. At worst they're seeing slowdowns and some crashes (which are being worked on as quickly as we can).

Most likely you have some bad RAM in your system, and that should be easy to replace.

Apple could figure this out by using an oscilloscope on the motherboard and watching for the power fault that causes the freeze. But Apple only has that equipment (and the technicians who know how to use it) at a few central repair sites and not in most Apple stores (the "geniuses" have no idea).

But, they could also swap your RAM out and see if the problem goes away -- which is usually the fastest way to diagnose bad RAM outside of a hardware lab.

Sound's like you haven't read all the Problem Reports about LR 4.1.

A Software can absolutely cause Crashes and System freezes. Caused by bad Programming and Memory missmanagement. ....

It makes me absolutely curious, how you can deny any Problem with LR and shove all the Problems on the Hardware. You can run all sorts of Benchmarks and Stresstests and still the System doesn't crash. While you can crash and freeze your System with LR 4.1. So for me the Problem is caused by LR, and not the System.

No, applications cannot cause the whole system to hang or reboot. Only bugs in the OS, low level drivers, or hardware faults can cause the entire system to hang or reboot. That is true regardless of the application.

An application bug can crash the application or hang the application. A memory management problem (leaks) can slow the system when it forces excessive paging - but it cannot freeze or reboot the system unless there is a bug in the OS or drivers.

In this case, I know from theory and experience that system hangs and reboots are caused by OS, low level driver, or hardware faults. I also know that by far the most common cause is bad RAM, followed by bad motherboards, bad drivers, bad CPUs, and bad power supplies.

LR 4.1 may trigger the fault in your hardware by stressing it, but it is not the underlying cause. You still have defective hardware that can cause problems with other application (like the OP that mentions LR and PSE causing system freezes).

Your other topic just talks about LR 4.1 being slow. But that has nothing to do with a system locking up. There is a big difference between slow and a system freeze.
