Lightroom v 4.2 overheating Imac
Nov 7, 2012

Hi All,

I am using an old 2006 model Imac 2.16 with 3GB of RAM. Also, I am a long time LR and PS user and am currently using LR version 4.2 and CS6.

I installed LR v4.0 when it first came out and had no issues with it at all. I have processed large volumes of images from 5D2, D300, D700, D3S, D4 and D800 with no issue (albeit the D800 is a little slow on my iMac) and no overheating.

I recently upgraded the software to LR version 4.2 and now I am having severe issues with overheating. I have a heat monitor installed on my Imac. It typically runs at about 35 degrees but as soon as I open LR 4.2 the temp raises to around 50 degrees and my Imac starts to freeze up.

I don't even need to be in the develop module. It overheats in the Library module as well.

This seems to be an issue with LR4.2 only as I have no overheating issue with CS6 or CS5 and non with version 4.0. I can process images in Photoshop all day without an issue.

So, the questions are:

1. Is anyone else having a similar issue?

2. Any suggestions for a fix?

BTW, I do intend to upgrade my Imac but am waiting for the new units to come out in December before making a purchase. Unfortunately, I have a lot of processing to do between now and then.

Thanks in advance for any help you can throw my way.
