The older MacBooks & MacBook Pro’s didn’t offer USB boot support. The first Mac was the MacBook Air which came out in January 2008.

It’s been a while that I’ve had to worry about it but I do believe the 2007 & 2008 models are the last ones that required boot up from either the internal optical drive or an external FireWire drive (prepped with Mac OS-X as a bootable drive).

You’ll need to find the original grey CD that came with the system or the retail copy of the OS-X CD to gain access via the optical drive or leverage a friends Mac using Target Disk Mode via a FireWire connection.

There are five different logic boards for the MacBook Pro (Retina, 15-inch, Mid 2015).

1. 2.2 GHz
2. 2.5 GHz
3. 2.5 GHz with dual graphics
4. 2.8 GHz
5. 2.8 GHz with dual graphics

Can I replace a bad 2.2 GHz board with a 2.5 or 2.8 board?

Swap an integrated graphics for dual graphics?

There are some differences between the IG models Vs the DG models logic boards as the IG models only have one fan and the DG models have dual fans.

I would stick with the same graphics model (IG vs DG) your system is as being the simpler direction. If you have a IG model you still can upgrade it to a DG model. But you’ll need the second fan as well as a different heat sink and gasket.

Freezer section of my fridge will freeze then hours later I will find it thawing out

Then maybe a few hours later everything is frozen again

Yes food thawed

I put a coin on a cup of frozen water

The next day it was at the bottom of the cup

Hence the ice melted and the coin sank so I know for sure it thawed
