I recently acquired a 2010 13" MacBook Pro. When attempting to boot to a Leopard installer on a USB drive, I am greeted with a kernel panic. There is no specific error message but instead prompts me to restart.
However, I tried booting from a hard drive in my early 2008 MacBook (with clean install of Lion) and it runs. However, there is extreme lag due to the high CPU usage. Task manager indicates kernel_task is using 150%+ of the CPU. This Lion install is near clean and runs perfectly on my MacBook. Upon successfully getting into Lion, I was greeted with a "problem report for mac os x". I can't copy paste it because of the lag (and I'm using a different machine to type this question) but one of the lines in the details suggests CPU issues...
panic(cpu 0 caller 0x001A9C68): Kernel trap at 0x4c76a81c, type 14=page fault, registers
. The next lines detail the registers and following that is a backtrace. I don't know what register and backtrace are.
Also, the computer is quite hot and there is no load. I performed a PRAM reset because, initially, the issues booting and no audio prompted me. Audio works now when it turns on.
I'm concerned the CPU is failing on the motherboard but I'm curious about what you [the community] think. Does this involve reflowing/replacing the CPU? How can I fix this?
I took photos of the kernel panic log window and the task manager. Upon request, I can post those.
