I was using Macbook Pro (13” Display with 2.5 GHz processor) without any problem until I started using Mackie Onyx Satellite Firewire audio interface with my laptop. When I connect it first time I did not receive any problem. I was using it form last month without any problem but yesterday when I cheked my iStat Pro application, I found my CPU temperature was almost 67 degree Celsius while it was giving just 15 to 25 degree Celsius. iStat Pro is a software which is used to get information about your Macbook. iStat Pro is a highly configurable widget that lets you monitor every aspect of your Mac, including CPU, memory, disks, network, battery, temperatures, fans, load & uptime and processes. iStat Pro can do it all. I made lots of serch on this topic and found that this is popular issue and related to Agere Firewire Chipset. I want to know is there any solution for this issue? Does it create dissimilarity if you utilize a daisy chain setup with an outside hard drive in between the device and the audio interface, or a repeater cable, or something of that scenery?
