My old Mac crashes a lot. I’m wondering if it’s because of some bad third-party extension.

Here’s how to list non-Apple kernel extensions (kext’s):

kextstat | grep -v apple

Our new MacBook Pro Retina arrived while we were in Hawaii.

Our old MacBook Pro was getting long in the tooth. It was a pre-unibody, 2007 model, 2.4 GHz Intel Core 2 Duo with 4 GB of RAM, a 500 GB spinning disk drive, and OS X 10.6.8 (Snow Leopard).

The new one has a Retina display, 2.8 GHz processor, 16 GB RAM and a 1 TB SSD and it’s running OS X 10.9.4 (Mavericks).

It’s been challenging to migrate files from the old laptop to the new one, as the old one keeps crashing.
